Hematologic Malignancies

Novel therapies are poised to dramatically change frontline therapy for acute myeloid leukemia (AML), and they have the potential to replace chemotherapy, a hematologist/oncologist told colleagues at the virtual Acute Leukemia Forum of Hemedicus.

But more work needs to be done, noted Alexander Perl, MD, MS, associate professor at the University of Pennsylvania, Philadelphia. While advances have transformed AML treatment in the relapsed/refractory setting, “we’re just not seeing that substantive improvement” for newly diagnosed patients, he said. “We need to find the disease-modifying drugs that work in the relapsed/refractory setting and move those frontline. That’s where we’re going to see the transformations.”

Research suggests that low-intensity therapy holds tremendous promise, he said, “with the idea that we could make therapy much more tolerable for the vast majority of patients affected by AML, who, as we know, are older patients.”

Dr. Perl highlighted the 2020 VIALE-A study – venetoclax/azacitidine versus azacitidine/placebo – which reported that “in previously untreated patients who were ineligible for intensive chemotherapy, overall survival was longer and the incidence of remission was higher among patients who received azacitidine plus venetoclax than among those who received azacitidine alone.”

Venetoclax promotes apoptosis in leukemia cells, Dr. Perl said. “To a certain extent, you can think of it as putting the rubber to the road in terms of what actually chemotherapy is designed to do, which is to make leukemic blasts apoptose. It does so without DNA damage and with much less toxicity to the patient. Therefore it can be added to any number of regimens – granted, with mild suppression, but with relatively little extramedullary toxicity.”

Dr. Perl noted that the venetoclax arm “showed a higher response rate than azacitidine in pretty much every subgroup that was looked at, whether patients had de novo leukemia, secondary leukemia, multiple mutational complements, various different karyotypes. The response rates on this study are as high as what we often will see with intensive chemotherapy.” He added that “the winning arm on this trial seems to hold up against any low-intensity therapy, and I would argue against many high-intensity therapies in older patients.”

As for other targeted agents, isocitrate dehydrogenase (IDH) inhibitors “are very promising drugs in the relapsed/refractory setting, which is primarily where these drugs are given. In regard to frontline treatment, “data are coming from a very small study, but they’re very encouraging. It’s hard to entirely say that we’re ready to change practice based on this. But it’s very encouraging – the idea that earlier use of a drug-targeting IDH mutation might lead to substantially better outcomes.”

Moving forward, he said, “we could put all of our eggs in one basket and use many active drugs [at] front line. Or we can perhaps be smart about sequencing these drugs one after another, or using more intensive approaches followed by maintenance approaches followed by more intensive approaches.”

This approach is similar to strategies in myeloma patients “who less and less are relying on an autologous transplant for durable control of their disease, and more and more are using low-intensity biologically targeted drugs,” he said.

The Acute Leukemia Forum is held by Hemedicus, which is owned by the same company as this news organization.

Dr. Perl reported numerous disclosures, including relationships with Daiichi Sankyo, Abbvie, and Astellas.

Physicians are gaining a greater understanding of the pathophysiology of chronic graft-versus-host disease (cGVHD) in allo-hematopoietic cell transplantation (allo-HCT), a hematologist/oncologist told colleagues, and novel treatments are being tested.

However, options remain limited. There’s only one Food and Drug Administration–approved therapy for cGVHD that’s failed one or more treatments, and clinical trials remain a crucial option in some cases, said Mary E.D. Flowers, MD, professor of medicine at the University of Washington’s Fred Hutchinson Cancer Research Center, Seattle, in a presentation at the virtual Acute Leukemia Forum of Hemedicus.

According to Dr. Flowers, cGVHD – a product of a graft’s “immunological assault” against the person receiving a transplant – occurs in 40% of patients within a year after allo-HCT. The disorder “is associated with a poor quality of life, disability, and increased mortality after allo-transplantation,” she said. “It’s a syndrome that can be inflammatory and fibrotic. It involves several organs – the skin, the mouth, the eyes, the lungs, the GI tract.”

The median length of treatment after peripheral blood stem cell transplant is 3.5 years, Dr. Flowers said. Seven years after treatment, 10% of those who are alive – and have avoided relapse – will still need treatment. “Corticosteroids remain the first-line [treatment], at 0.5-1.0 [mg/kg], but they do not control at least 40% of the patients with cGVHD.”

In regard to pathophysiology, she highlighted a 2017 report that presented findings about the pathophysiology of cGVHD. The findings, the report authors wrote, “have yielded a raft of potential new therapeutics, centered on naive T-cell depletion, interleukin-17/21 inhibition, kinase inhibition, regulatory T-cell restoration, and CSF-1 inhibition.”

For now, no agents other than corticosteroids have shown benefit in cGVHD as initial therapy, Dr. Flowers said. In fact, several trials closed early from lack of benefit. But trials continue, she said: Results are pending for a completed phase 3 trial of ibrutinib, a Bruton tyrosine kinase inhibitor, plus steroids for initial treatment of cGVHD. Nearly 500 patients were enrolled, she said. And there’s an ongoing phase 2/3 trial of itacitinib, a Janus kinase 1 inhibitor plus steroids as initial treatment.

Dr. Flowers highlighted the case of a patient with moderate cGVHD. The patient was treated with infection prophylaxis, supportive care for oral and eyes manifestations, and prednisone 0.5 mg/kg (at a lower dose because of diabetes) plus a substitution of tacrolimus with sirolimus, a calcineurin inhibitor.

Why sirolimus? At this early point in progression, she said, the patient didn’t necessarily need systemwide chemo-suppression, and calcineurin inhibitors can be “quite effective” in management of inflammation in the liver. “It would be a completely different story once the patient develops severe cGVHR.” In that case, she said, calcineurin inhibitors wouldn’t be appropriate.

The patient’s status deteriorated to severe cGVHD, and sirolimus was replaced with ibrutinib. Other drugs were added to prevent infection and treat bronchiolitis obliterans syndrome.

In general, “the goal of the treatment is get adequate control of clinical manifestations and prevent more severe disease from developing,” Dr. Flowers said.

In response to a question about polypharmacy in patient with advanced disease – “we tend not to peel those drugs off” – Dr. Flowers said she does see new patients who appear to be taking too many medications. “They are on five drugs, and I say, ‘What are we doing?’ ”

Quite often, Dr. Flowers said, she doesn’t add therapies to existing ones but instead looks for substitutes. “A clinical lesson that I feel that I learned over time is: Ask your questions first. What would you like to see in 3 months? Or 6 months? Before you just add another therapy, do you really know what the trajectory of a disease might be?”

Acalabrutinib, a next-generation Bruton tyrosine kinase inhibitor, provides prolonged progression-free survival and better tolerability, compared with standard-of-care regimens for relapsed or refractory chronic lymphocytic leukemia (CLL), according to final results from the phase 3 ASCEND study.

The estimated 18-month progression-free survival (PFS) at a median of 22 months was 82% in 155 patients treated with acalabrutinib, compared with 48% in 155 treated with investigator’s choice of either idelalisib-rituximab (IdR) or bendamustine-rituximab (BR), which were given in 119 and 36 patients, respectively, Paolo Ghia, MD, PhD, reported at the Society of Hematologic Oncology virtual meeting.

The benefits of acalabrutinib were apparent regardless of high-risk genetic characteristics: Those with and without both del(17p) and TP53 mutations had similarly good PFS outcomes with acalabrutinib versus IdR/BR (HRs, 0.11 and 0.29, respectively), as did those with versus without unmutated IgVH (HRs, 0.28 and 0.30, respectively), said Dr. Ghia, professor of medical oncology at the Università Vita-Salute San Raffaele and IRCCS Ospedale San Raffaele, Milan.

The median overall survival was not reached in either arm, but estimated 18-month OS was 88% in both groups, likely because of the crossover being allowed for nonresponders in the IdR/BR groups, he noted.
 

Overall responses

The investigator-assessed overall response rates, including partial response or better, were also similar in the groups at 80% and 84%, respectively, and ORR, including partial response with lymphocytosis, was 92% versus 88%.

The duration of response was not reached in the acalabrutinib arm versus 18 months with IdR/BR, and estimated duration of response was 85% versus 49%.

The median drug exposure with acalabrutinib was approximately double that with IdR and about four times that of BR, Dr. Ghia said, noting that the difference between acalabrutinib and BR is explained by the short 6-month duration of treatment with BR, but the difference between acalabrutinib and IdR is because of adverse events (AEs).
 

Adverse events

AEs were the most common reason for treatment discontinuation in all three groups, but they led to discontinuation in only 16% with acalabrutinib versus 56% with IdR, he added.

The rates of AEs and AEs of clinical interest were generally similar to those reported at the interim analysis as presented in 2019 at the European Hematology Association annual meeting and published in the Journal of Clinical Oncology, despite the additional 6 months of follow up, he said.

Additionally, the incidence of grade 3 or higher AEs, serious AEs, and treatment-related AEs were all greater with IdR than with acalabrutinib or BR. The most common AEs with acalabrutinib were headache, neutropenia, diarrhea, and upper-respiratory infection, which were mostly grade 1 or 2. The most common grade 3 or higher AEs were neutropenia, anemia, and pneumonia, which were reported in 12%, 17%, and 7% of patients.
 

Confirmatory results

“The final results from the ASCEND study confirm the findings at the interim analysis and support the favorable efficacy and safety of acalabrutinib versus standard-of-care regimens ... in patients with relapsed/refractory CLL,” Dr. Ghia said.

“Overall, these final results from ASCENT support the use of acalabrutinib in patients with relapsed/refractory CLL, including those with high-risk genetic features.”

The most common grade 3 or higher AEs were neutropenia, anemia, and pneumonia, which were reported in 12%, 17%, and 7% of patients.
 

Confirmatory results

“The final results from the ASCEND study confirm the findings at the interim analysis and support the favorable efficacy and safety of acalabrutinib versus standard-of-care regimens ... in patients with relapsed/refractory CLL,” Dr. Ghia said.

“Overall, these final results from ASCENT support the use of acalabrutinib in patients with relapsed/refractory CLL, including those with high-risk genetic features.”

This study was sponsored by Acerta Pharma. Dr. Ghia reported consulting or advisory roles, grant or research funding, and/or honoraria from Abbvie, BeiGene, Janssen, Gilead Sciences, Sunesis Pharmaceuticals, Juno Therapeutics, ArQule, Adaptive Biotechnologies, Dynamo Therapeutics, MEI Pharma, and Novartis.

Disparities driven by socioeconomic factors have been shown to affect outcomes for patients with a variety of cancer types. Researchers found that this was also true for patients with multiple myeloma, according to a report published in Hematology/Oncology and Stem Cell Therapy.

In particular, survival was affected by a variety of socioeconomic factors.

Researchers conducting the study queried the National Cancer Database for patients diagnosed with multiple myeloma between 2004 and 2016. Only those 56,102 patients who received systemic therapy as the first-line treatment were included, according to Thejus T. Jayakrishnan, MD, of Allegheny Health Network, Pittsburgh, and colleagues.

Enrollment rates for therapy were calculated using receiving systemic therapy as the incident event of interest (numerator) over time to initiation of therapy (denominator). The incident rate ratios were analyzed using Poisson regression. A multivariate Cox proportional hazards model was used for survival analysis of 50,543 patients, and differences were determined as hazard ratios.

Significant differences

The study showed that therapy enrollment was significantly affected by race and sex (P < .005), with the enrollment rate for women and for non-Hispanic Blacks both being lower versus men and non-Hispanic Whites, respectively.

Advanced age, earlier year of diagnosis, lack of insurance or Medicaid, and higher comorbidity were found to be associated with poor survival (HR >1), whereas being a woman or a non-Hispanic Black (who were speculated to have more favorable cytogenetic profiles), having a higher income, and having treatment at an academic center were all associated with improved survival (each category at HR <1).

“Disparities in [multiple myeloma] exist and are caused by a complex interplay of multiple factors, with socioeconomic factors such as insurance and income playing a dominant role. The disparities not only exact high human cost but also negatively impact the economics of health care,” the researchers concluded.

The study was not funded and the authors reported that they had no relevant disclosures.

Canceled appointments, postponed surgeries, and delayed cancer diagnoses – all are a recipe for exhaustion for oncologists around the world, struggling to reach and treat their patients during the pandemic. Physicians and their teams felt the pain as COVID-19 took its initial march around the globe.

“We saw the distress of people with cancer who could no longer get to anyone on the phone. Their medical visit was usually canceled. Their radiotherapy session was postponed or modified, and chemotherapy postponed,” says Axel Kahn, MD, chairman of the board of directors of La Ligue Nationale Contre le Cancer (National League Against Cancer). “In the vast majority of cases, cancer treatment can be postponed or readjusted, without affecting the patient’s chances of survival, but there has been a lot of anxiety because the patients do not know that.”

The stay-at-home factor was one that played out across many months during the first wave.

“I believe that the ‘stay-home’ message that we transmitted was rigorously followed by patients who should have come to the emergency room much earlier and who, therefore, were admitted with a much more deteriorated general condition than in non-COVID-19 times,” says Benjamín Domingo Arrué, MD, from the department of medical oncology at Hospital Universitari i Politècnic La Fe in Valencia, Spain.

And in Brazil, some of the impact from the initial hit of COVID-19 on oncology is only now being felt, according to Laura Testa, MD, head of breast medical oncology, Instituto do Câncer do Estado de São Paulo.

“We are starting to see a lot of cancer cases that didn’t show up at the beginning of the pandemic, but now they are arriving to us already in advanced stages,” she said. “These patients need hospital care. If the situation worsens and goes back to what we saw at the peak of the curve, I fear the public system won’t be able to treat properly the oncology patients that need hospital care and the patients with cancer who also have COVID-19.”

But even as health care worker fatigue and concerns linger, oncologists say that what they have learned in the last 6 months has helped them prepare as COVID-19 cases increase and a second global wave kicks up.
 

Lessons from the first wave

In the United States, COVID-19 hit different regions at different times and to different degrees. One of the areas hit first was Seattle.

“We jumped on top of this, we were evidence based, we put things in place very, very quickly,” said Julie Gralow, MD, professor at the University of Washington and the Fred Hutchinson Cancer Research Center, both in Seattle.

“We did a really good job keeping COVID out of our cancer centers,” Dr. Gralow said. “We learned how to be super safe, and to keep symptomatic people out of the building, and to limit the extra people they could bring with them. It’s all about the number of contacts you have.”

The story was different, though, for oncologists in several other countries, and sometimes it varied immensely within each nation.

“We treated fewer patients with cancer during the first wave,” says Dirk Arnold, MD, medical director of the Asklepios Tumor Center Hamburg (Germany), in an interview. “In part, this was because staff were quarantined and because we had a completely different infrastructure in all of the hospitals. But also fewer patients with cancer came to the clinic at all. A lot of resources were directed toward COVID-19.” 

In Spain, telemedicine helped keep up with visits, but other areas felt the effect of COVID-19 patient loads.

“At least in the oncology department of our center, we have practically maintained 100% of visits, mostly by telephone,” says Dr. Arrué, “but the reality is that our country has not yet been prepared for telemedicine.”

Laura Mezquita, MD, of the department of medical oncology at Hospital Clinic de Barcelona, describes a more dramatic situation: “We have seen how some of our patients, especially with metastatic disease, have been dismissed for intensive care and life-support treatments, as well as specific treatments against COVID-19 (tocilizumab, remdesivir, etc.) due to the general health collapse of the former wave,” she said. She adds that specific oncologic populations, such as those with thoracic tumors, have been more affected.
 

Distress among oncologists 

Many oncologists are still feeling stressed and fatigued after the first wave, just as a second string of outbreaks is on its way. 

A survey presented at last month’s ESMO 2020 Congress found that, in July-August, moral distress was reported by one-third of the oncologists who responded, and more than half reported a feeling of exhaustion. 

“The tiredness and team exhaustion is noticeable,” said Dr. Arnold. “We recently had a task force discussion about what will happen when we have a second wave and how the department and our services will adapt. It was clear that those who were at the very front in the first wave had only a limited desire to do that again in the second wave.”

Another concern: COVID-19’s effect on staffing levels. 

“We have a population of young caregivers who are affected by the COVID-19 disease with an absenteeism rate that is quite unprecedented,” said Sophie Beaupère, general delegate of Unicancer since January.

She said that, in general, the absenteeism rate in the cancer centers averages 5%-6%, depending on the year. But that rate is now skyrocketing.
 

Stop-start cycle for surgery

As caregivers quarantined around the world, more than 10% of patients with cancer had treatment canceled or delayed during the first wave of the pandemic, according to another survey from ESMO, involving 109 oncologists from 18 countries.

Difficulties were reported for surgeries by 34% of the centers, but also difficulties with delivering chemotherapy (22% of centers), radiotherapy (13.7%), and therapy with checkpoint inhibitors (9.1%), monoclonal antibodies (9%), and oral targeted therapy (3.7%).

Stopping surgery is a real concern in France, noted Dr. Kahn, the National League Against Cancer chair. He says that in regions that were badly hit by COVID-19, “it was not possible to have access to the operating room for people who absolutely needed surgery; for example, patients with lung cancer that was still operable. Most of the recovery rooms were mobilized for resuscitation.”

There may be some solutions, suggested Thierry Breton, director general of the National Institute of Cancer in France. “We are getting prepared, with the health ministry, for a possible increase in hospital tension, which would lead to a situation where we would have to reschedule operations. Nationally, regionally, and locally, we are seeing how we can resume and prioritize surgeries that have not been done.”
 

Delays in cancer diagnosis

While COVID-19 affected treatment, many oncologists say the major impact of the first wave was a delay in diagnosing cancer. Some of this was a result of the suspension of cancer screening programs, but there was also fear among the general public about visiting clinics and hospitals during a pandemic.

“We didn’t do so well with cancer during the first wave here in the U.K.,” said Karol Sikora, PhD, MBBChir, professor of cancer medicine and founding dean at the University of Buckingham Medical School, London. “Cancer diagnostic pathways virtually stalled partly because patients didn’t seek help, but getting scans and biopsies was also very difficult. Even patients referred urgently under the ‘2-weeks-wait’ rule were turned down.” 

In France, “the delay in diagnosis is indisputable,” said Dr. Kahn. “About 50% of the cancer diagnoses one would expect during this period were missed.” 

“I am worried that there remains a major traffic jam that has not been caught up with, and, in the meantime, the health crisis is worsening,” he added.  

In Seattle, Dr. Gralow said the first COVID-19 wave had little impact on treatment for breast cancer, but it was in screening for breast cancer “where things really got messed up.”

“Even though we’ve been fully ramped up again,” she said, concerns remain. To ensure that screening mammography is maintained, “we have spaced out the visits to keep our waiting rooms less populated, with a longer time between using the machine so we can clean it. To do this, we have extended operating hours and are now opening on Saturday.

“So we’re actually at 100% of our capacity, but I’m really nervous, though, that a lot of people put off their screening mammogram and aren’t going to come in and get it.

“Not only did people get the message to stay home and not do nonessential things, but I think a lot of people lost their health insurance when they lost their jobs,” she said, and without health insurance, they are not covered for cancer screening.
 

Looking ahead, with a plan

Many oncologists agree that access to care can and must be improved – and there were some positive moves.

“Some regimens changed during the first months of the pandemic, and I don’t see them going back to the way they were anytime soon,” said Dr. Testa. “The changes/adaptations that were made to minimize the chance of SARS-CoV-2 infection are still in place and will go on for a while. In this context, telemedicine helped a lot. The pandemic forced the stakeholders to step up and put it in place in March. And now it’s here to stay.”

The experience gained in the last several months has driven preparation for the next wave.

“We are not going to see the disorganization that we saw during the first wave,” said Florence Joly, MD, PhD, head of medical oncology at the Centre François Baclesse in Caen, France. “The difference between now and earlier this year is that COVID diagnostic tests are available. That was one of the problems in the first wave. We had no way to diagnose.”

On the East Coast of the United States, medical oncologist Charu Aggarwal, MD, MPH, is also optimistic: “I think we’re at a place where we can manage.”

“I believe if there was going to be a new wave of COVID-19 cases we would be: better psychologically prepared and better organized,” said Dr. Aggarwal, assistant professor of medicine in the hematology-oncology division at the University of Pennsylvania, Philadelphia. “We already have experience with all of the tools, we have telemedicine available, we have screening protocols available, we have testing, we are already universally masking, everyone’s hand-washing, so I do think that means we would be okay.” 

Dr. Arnold agreed that “we are much better prepared than for the first wave, but … we have immense tasks in the area of patient management, the digitization of patient care, the clear allocation of resources when there is a second or third wave. In many areas of preparation, I believe, unfortunately, we are not as well positioned as we had actually hoped.” 

The first wave of COVID hit cancer services in the United Kingdom particularly hard: One modeling study suggested that delays in cancer referrals will lead to thousands of additional deaths and tens of thousands of life-years lost.

“Cancer services are working at near normal levels now, but they are still fragile and could be severely compromised again if the NHS [National Health Service] gets flooded by COVID patients,” said Dr. Sikora.

The second wave may be different. “Although the number of infections has increased, the hospitalizations have only risen a little. Let’s see what happens,” he said in an interview. Since then, however, infections have continued to rise, and there has been an increase in hospitalizations. New social distancing measures in the United Kingdom were put into place on Oct. 12, with the aim of protecting the NHS from overload.

Dr. Arrué describes it this way: “The reality is that the ‘second wave’ has left behind the initial grief and shock that both patients and health professionals experienced when faced with something that, until now, we had only seen in the movies.” The second wave has led to new restrictions – including a partial lockdown since the beginning of October.

Dr. Aggarwal says her department recently had a conference with Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, about the impact of COVID-19 on oncology.

“I asked him what advice he’d give oncologists, and he said to go back to as much screening as you were doing previously as quickly as possible. That’s what must be relayed to our oncologists in the community – and also to primary care physicians – because they are often the ones who are ordering and championing the screening efforts.”

“We jumped on top of this, we were evidence based, we put things in place very, very quickly,” said Julie Gralow, MD, professor at the University of Washington and the Fred Hutchinson Cancer Research Center, both in Seattle.

“We did a really good job keeping COVID out of our cancer centers,” Dr. Gralow said. “We learned how to be super safe, and to keep symptomatic people out of the building, and to limit the extra people they could bring with them. It’s all about the number of contacts you have.”

The story was different, though, for oncologists in several other countries, and sometimes it varied immensely within each nation.

“We treated fewer patients with cancer during the first wave,” says Dirk Arnold, MD, medical director of the Asklepios Tumor Center Hamburg (Germany), in an interview. “In part, this was because staff were quarantined and because we had a completely different infrastructure in all of the hospitals. But also fewer patients with cancer came to the clinic at all. A lot of resources were directed toward COVID-19.” 

In Spain, telemedicine helped keep up with visits, but other areas felt the effect of COVID-19 patient loads.

“At least in the oncology department of our center, we have practically maintained 100% of visits, mostly by telephone,” says Dr. Arrué, “but the reality is that our country has not yet been prepared for telemedicine.”

Laura Mezquita, MD, of the department of medical oncology at Hospital Clinic de Barcelona, describes a more dramatic situation: “We have seen how some of our patients, especially with metastatic disease, have been dismissed for intensive care and life-support treatments, as well as specific treatments against COVID-19 (tocilizumab, remdesivir, etc.) due to the general health collapse of the former wave,” she said. She adds that specific oncologic populations, such as those with thoracic tumors, have been more affected.
 

Distress among oncologists 

Many oncologists are still feeling stressed and fatigued after the first wave, just as a second string of outbreaks is on its way. 

A survey presented at last month’s ESMO 2020 Congress found that, in July-August, moral distress was reported by one-third of the oncologists who responded, and more than half reported a feeling of exhaustion. 

“The tiredness and team exhaustion is noticeable,” said Dr. Arnold. “We recently had a task force discussion about what will happen when we have a second wave and how the department and our services will adapt. It was clear that those who were at the very front in the first wave had only a limited desire to do that again in the second wave.”

Another concern: COVID-19’s effect on staffing levels. 

“We have a population of young caregivers who are affected by the COVID-19 disease with an absenteeism rate that is quite unprecedented,” said Sophie Beaupère, general delegate of Unicancer since January.

She said that, in general, the absenteeism rate in the cancer centers averages 5%-6%, depending on the year. But that rate is now skyrocketing.
 

Stop-start cycle for surgery

As caregivers quarantined around the world, more than 10% of patients with cancer had treatment canceled or delayed during the first wave of the pandemic, according to another survey from ESMO, involving 109 oncologists from 18 countries.

Difficulties were reported for surgeries by 34% of the centers, but also difficulties with delivering chemotherapy (22% of centers), radiotherapy (13.7%), and therapy with checkpoint inhibitors (9.1%), monoclonal antibodies (9%), and oral targeted therapy (3.7%).

Stopping surgery is a real concern in France, noted Dr. Kahn, the National League Against Cancer chair. He says that in regions that were badly hit by COVID-19, “it was not possible to have access to the operating room for people who absolutely needed surgery; for example, patients with lung cancer that was still operable. Most of the recovery rooms were mobilized for resuscitation.”

There may be some solutions, suggested Thierry Breton, director general of the National Institute of Cancer in France. “We are getting prepared, with the health ministry, for a possible increase in hospital tension, which would lead to a situation where we would have to reschedule operations. Nationally, regionally, and locally, we are seeing how we can resume and prioritize surgeries that have not been done.”
 

Delays in cancer diagnosis

While COVID-19 affected treatment, many oncologists say the major impact of the first wave was a delay in diagnosing cancer. Some of this was a result of the suspension of cancer screening programs, but there was also fear among the general public about visiting clinics and hospitals during a pandemic.

“We didn’t do so well with cancer during the first wave here in the U.K.,” said Karol Sikora, PhD, MBBChir, professor of cancer medicine and founding dean at the University of Buckingham Medical School, London. “Cancer diagnostic pathways virtually stalled partly because patients didn’t seek help, but getting scans and biopsies was also very difficult. Even patients referred urgently under the ‘2-weeks-wait’ rule were turned down.” 

In France, “the delay in diagnosis is indisputable,” said Dr. Kahn. “About 50% of the cancer diagnoses one would expect during this period were missed.” 

“I am worried that there remains a major traffic jam that has not been caught up with, and, in the meantime, the health crisis is worsening,” he added.  

In Seattle, Dr. Gralow said the first COVID-19 wave had little impact on treatment for breast cancer, but it was in screening for breast cancer “where things really got messed up.”

“Even though we’ve been fully ramped up again,” she said, concerns remain. To ensure that screening mammography is maintained, “we have spaced out the visits to keep our waiting rooms less populated, with a longer time between using the machine so we can clean it. To do this, we have extended operating hours and are now opening on Saturday.

“So we’re actually at 100% of our capacity, but I’m really nervous, though, that a lot of people put off their screening mammogram and aren’t going to come in and get it.

“Not only did people get the message to stay home and not do nonessential things, but I think a lot of people lost their health insurance when they lost their jobs,” she said, and without health insurance, they are not covered for cancer screening.
 

Looking ahead, with a plan

Many oncologists agree that access to care can and must be improved – and there were some positive moves.

“Some regimens changed during the first months of the pandemic, and I don’t see them going back to the way they were anytime soon,” said Dr. Testa. “The changes/adaptations that were made to minimize the chance of SARS-CoV-2 infection are still in place and will go on for a while. In this context, telemedicine helped a lot. The pandemic forced the stakeholders to step up and put it in place in March. And now it’s here to stay.”

The experience gained in the last several months has driven preparation for the next wave.

“We are not going to see the disorganization that we saw during the first wave,” said Florence Joly, MD, PhD, head of medical oncology at the Centre François Baclesse in Caen, France. “The difference between now and earlier this year is that COVID diagnostic tests are available. That was one of the problems in the first wave. We had no way to diagnose.”

On the East Coast of the United States, medical oncologist Charu Aggarwal, MD, MPH, is also optimistic: “I think we’re at a place where we can manage.”

“I believe if there was going to be a new wave of COVID-19 cases we would be: better psychologically prepared and better organized,” said Dr. Aggarwal, assistant professor of medicine in the hematology-oncology division at the University of Pennsylvania, Philadelphia. “We already have experience with all of the tools, we have telemedicine available, we have screening protocols available, we have testing, we are already universally masking, everyone’s hand-washing, so I do think that means we would be okay.” 

Dr. Arnold agreed that “we are much better prepared than for the first wave, but … we have immense tasks in the area of patient management, the digitization of patient care, the clear allocation of resources when there is a second or third wave. In many areas of preparation, I believe, unfortunately, we are not as well positioned as we had actually hoped.” 

The first wave of COVID hit cancer services in the United Kingdom particularly hard: One modeling study suggested that delays in cancer referrals will lead to thousands of additional deaths and tens of thousands of life-years lost.

“Cancer services are working at near normal levels now, but they are still fragile and could be severely compromised again if the NHS [National Health Service] gets flooded by COVID patients,” said Dr. Sikora.

The second wave may be different. “Although the number of infections has increased, the hospitalizations have only risen a little. Let’s see what happens,” he said in an interview. Since then, however, infections have continued to rise, and there has been an increase in hospitalizations. New social distancing measures in the United Kingdom were put into place on Oct. 12, with the aim of protecting the NHS from overload.

Dr. Arrué describes it this way: “The reality is that the ‘second wave’ has left behind the initial grief and shock that both patients and health professionals experienced when faced with something that, until now, we had only seen in the movies.” The second wave has led to new restrictions – including a partial lockdown since the beginning of October.

Dr. Aggarwal says her department recently had a conference with Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, about the impact of COVID-19 on oncology.

“I asked him what advice he’d give oncologists, and he said to go back to as much screening as you were doing previously as quickly as possible. That’s what must be relayed to our oncologists in the community – and also to primary care physicians – because they are often the ones who are ordering and championing the screening efforts.”

An updated European Society for Medical Oncology (ESMO) clinical practice guidelines were released to provide key recommendations on the management of chronic lymphocytic leukemia (CLL).

The guidelines were developed by a multidisciplinary group of experts from different institutions and countries in Europe and provide levels of evidence and grades of recommendation where applicable for issues regarding prognosis and treatment decisions in CLL. Such decisions depend on genetic and clinical factors such as age, stage, and comorbidities. The guidelines also focus on new therapies targeting B-cell-receptor pathways or defect mechanism of apoptosis, which have been found to induce long-lasting remissions. The guidelines were endorsed by the European Hematology Association (EHA) through the Scientific Working Group on CLL/European Research Initiative on CLL (ERIC), according to the report published online the Annals of Oncology.

These clinical practice guidelines were developed in accordance with the ESMO standard operating procedures for clinical practice guidelines development with use of relevant literature selected by the expert authors. Statements without grading were considered justified as standard clinical practice by the experts and the ESMO faculty.

Below are some highlights of the guidelines, which cover a wide array of topics regarding the diagnosis, staging, treatment, and progression of CLL disease.
 

Diagnosis

The guidelines indicate that CLL diagnosis is usually possible by immunophenotyping of peripheral blood only and that lymph node (LN) biopsy and/or bone marrow biopsy may be helpful if immunophenotyping is not conclusive for the diagnosis of CLL, according to Barbara Eichhorst, MD, of the University of Cologne (Germany) and colleagues on behalf of the ESMO guidelines committee.

Staging and risk assessment

Early asymptomatic-stage disease does not need further risk assessment, but after the first year, when all patients should be seen at 3-monthly intervals, patients can be followed every 3-12 months. The interval would depend on burden and dynamics of the disease obtained by the using history and physical examinations, including a careful palpation of all LN areas, spleen, and liver, as well as assessing complete blood cell count and differential count, according to the report.

Advanced- and symptomatic-stage disease requires a broader examination including imaging, history and status of relevant infections, and fluorescent in situ hybridization (FISH) assays for the detection of deletion of the chromosome 17 (del[17p]) affecting the tumor protein p53 expression and, in the absence of del(17p), TP53 sequencing for detection of TP53 gene mutation, according to the authors.

Prognostication

Two clinical staging systems are typically used in CLL. Both Binet and Rai staging systems separate three groups of patients with different prognosis, although “as a consequence of more effective therapy, the overall survival (OS) of patients with advanced stage has improved and the relevance of the staging systems for prognostication has decreased,” according to the report.

The recent addition of genetic markers has also proved highly relevant to identifying patients with different prognoses and to guide treatment.
 

Therapy

Although CLL is an incurable disease, choice and application of treatment are strongly tied to the length of survival, according to the authors. The guidelines recommend Binet and Rai staging with clinical symptoms as relevant for treatment indication. In addition, the identification of del(17p), TP53 mutations, and IGHV status are relevant for choice of therapy and should be assessed prior to treatment.

The guidelines discuss specific treatment modalities for various stages of the disease, from early stages to relapse.

For frontline therapy, different treatment strategies are available including continuous treatment with Bruton tyrosine kinase (BTK)–inhibitors, such as ibrutinib, until progression or time-limited therapy with ChT backbone and CD20 antibodies. In addition, the Food and Drug Administration and European Medicines Agency have recently approved the combination of venetoclax plus obinutuzumab for first-line therapy of CLL.

Treatment decisions should include an assessment of IGHV and TP53 status, as well as patient-related factors such as comedication, comorbidities, preferences, drug availability, and potential of treatment adherence, according to the guidelines.

In case of symptomatic relapse within 3 years after fixed-duration therapy or nonresponse to therapy, the guidelines recommend that the therapeutic regimen should be changed, regardless of the type of first-line either to venetoclax plus rituximab for 24 months or to ibrutinib, acalabrutinib, or other BTK inhibitors (if available) as continuous therapy.

The guidelines also discuss the possible roles for hematopoietic stem cell transplantation and cellular therapies, as well as the treatment of the various complications that can arise in patients with CLL, and dealing with various aspects of disease progression.

No external funds were provided for the production of the guidelines. The authors of the report and members of the ESMO Guidelines Committee reported numerous disclosures regarding pharmaceutical and biotechnology companies.

How old is too old for a patient to undergo hematopoietic cell transplantation (HCT)? That’s the wrong question to ask, a hematologist/oncologist told colleagues at the virtual Acute Leukemia Forum of Hemedicus. Instead, he said, look at other factors such as disease status and genetics.

“Transplantation for older patients, even beyond the age of 70, is acceptable, as long as it’s done with caution, care, and wisdom. So we’re all not too old for transplantation, at least not today,” said Daniel Weisdorf, MD, professor of medicine and deputy director of the University of Minnesota Clinical and Translational Science Institute.

As he noted, acute myeloid leukemia (AML) is often fatal. Among the general population, “the expected survival life expectancy at age 75 is 98% at 1 year, and most people living at 75 go on to live more than 10 years,” he said. “But if you have AML, at age 75, you have 20% survival at 1 year, 4% at 3 years. And since the median age of AML diagnosis is 68, and 75% of patients are diagnosed beyond the age of 55, this becomes relevant.”

Risk factors that affect survival after transplantation “certainly include age, but that interacts directly with the comorbidities people accumulate with age, their assessments of frailty, and their Karnofsky performance status, as well as the disease phenotype and molecular genetic markers,” Dr. Weisdorf said. “Perhaps most importantly, though not addressed very much, is patients’ willingness to undertake intensive therapy and their life outlook related to patient-reported outcomes when they get older.”

Despite the lack of indications that higher age by itself is an influential factor in survival after transplant, “we are generally reluctant to push the age of eligibility,” Dr. Weisdorf said. He noted that recently published American Society of Hematology guidelines for treatment of AML over the age of 55 “don’t discuss anything about transplantation fitness because they didn’t want to tackle that.”

Overall survival (OS) at 1 year after allogenic transplants only dipped slightly from ages 51-60 to 71 and above, according to Dr. Weisdorf’s analysis of U.S. data collected by the Center for International Blood and Marrow Transplant Research for the time period 2005-2019.

OS was 67.6% (66.8%-68.3%) for the 41-50 age group (n = 9,287) and 57.9% (56.1%-59.8%) for the 71 and older group, Dr. Weisdorf found. Overall, OS dropped by about 4 percentage points per decade of age, he said, revealing a “modest influence” of advancing years.

His analysis of autologous transplant data from the same source, also for 2005-2019, revealed “essentially no age influence.” OS was 90.8% (90.3%-91.2%) for the 41-50 age group (n = 15,075) and 86.6% (85.9%-87.3%) for the 71 and older group (n = 7,247).

Dr. Weisdorf also highlighted unpublished research that suggests that cord-blood transplant recipients older than 70 face a significantly higher risk of death than that of younger patients in the same category. Cord blood “may be option of last resort” because of a lack of other options, he explained. “And it may be part of the learning curve of cord blood transplantation, which grew a little bit in the early 2000s, and maybe past 2010, and then fell off as everybody got enamored with the haploidentical transplant option.”

How can physicians make decisions about transplants in older patients? “The transplant comorbidity index, the specific comorbidities themselves, performance score, and frailty are all measures of somebody’s fitness to be a good candidate for transplant, really at any age,” Dr. Weisdorf said. “But we also have to recognize that disease status, genetics, and the risk phenotype remain critical and should influence decision making.”

However, even as transplant survival improves overall, “very few people are incorporating any very specific biological markers” in decision-making, he said. “We’ve gotten to measures of frailty, but we haven’t gotten to any biologic measures of cytokines or other things that would predict poor chances for doing well. So I’m afraid we’re still standing at the foot of the bed saying: ‘You look okay.’ Or we’re measuring their comorbidity index. But it is disappointing that we’re using mostly very simple clinical measures to decide if somebody is sturdy enough to proceed, and we perhaps need something better. But I don’t have a great suggestion what it should be.”

“Transplantation for older patients, even beyond the age of 70, is acceptable, as long as it’s done with caution, care, and wisdom. So we’re all not too old for transplantation, at least not today,” said Daniel Weisdorf, MD, professor of medicine and deputy director of the University of Minnesota Clinical and Translational Science Institute.

As he noted, acute myeloid leukemia (AML) is often fatal. Among the general population, “the expected survival life expectancy at age 75 is 98% at 1 year, and most people living at 75 go on to live more than 10 years,” he said. “But if you have AML, at age 75, you have 20% survival at 1 year, 4% at 3 years. And since the median age of AML diagnosis is 68, and 75% of patients are diagnosed beyond the age of 55, this becomes relevant.”

Risk factors that affect survival after transplantation “certainly include age, but that interacts directly with the comorbidities people accumulate with age, their assessments of frailty, and their Karnofsky performance status, as well as the disease phenotype and molecular genetic markers,” Dr. Weisdorf said. “Perhaps most importantly, though not addressed very much, is patients’ willingness to undertake intensive therapy and their life outlook related to patient-reported outcomes when they get older.”

Despite the lack of indications that higher age by itself is an influential factor in survival after transplant, “we are generally reluctant to push the age of eligibility,” Dr. Weisdorf said. He noted that recently published American Society of Hematology guidelines for treatment of AML over the age of 55 “don’t discuss anything about transplantation fitness because they didn’t want to tackle that.”

Overall survival (OS) at 1 year after allogenic transplants only dipped slightly from ages 51-60 to 71 and above, according to Dr. Weisdorf’s analysis of U.S. data collected by the Center for International Blood and Marrow Transplant Research for the time period 2005-2019.

OS was 67.6% (66.8%-68.3%) for the 41-50 age group (n = 9,287) and 57.9% (56.1%-59.8%) for the 71 and older group, Dr. Weisdorf found. Overall, OS dropped by about 4 percentage points per decade of age, he said, revealing a “modest influence” of advancing years.

His analysis of autologous transplant data from the same source, also for 2005-2019, revealed “essentially no age influence.” OS was 90.8% (90.3%-91.2%) for the 41-50 age group (n = 15,075) and 86.6% (85.9%-87.3%) for the 71 and older group (n = 7,247).

Dr. Weisdorf also highlighted unpublished research that suggests that cord-blood transplant recipients older than 70 face a significantly higher risk of death than that of younger patients in the same category. Cord blood “may be option of last resort” because of a lack of other options, he explained. “And it may be part of the learning curve of cord blood transplantation, which grew a little bit in the early 2000s, and maybe past 2010, and then fell off as everybody got enamored with the haploidentical transplant option.”

How can physicians make decisions about transplants in older patients? “The transplant comorbidity index, the specific comorbidities themselves, performance score, and frailty are all measures of somebody’s fitness to be a good candidate for transplant, really at any age,” Dr. Weisdorf said. “But we also have to recognize that disease status, genetics, and the risk phenotype remain critical and should influence decision making.”

However, even as transplant survival improves overall, “very few people are incorporating any very specific biological markers” in decision-making, he said. “We’ve gotten to measures of frailty, but we haven’t gotten to any biologic measures of cytokines or other things that would predict poor chances for doing well. So I’m afraid we’re still standing at the foot of the bed saying: ‘You look okay.’ Or we’re measuring their comorbidity index. But it is disappointing that we’re using mostly very simple clinical measures to decide if somebody is sturdy enough to proceed, and we perhaps need something better. But I don’t have a great suggestion what it should be.”

Patients with B-cell lymphoma are immunocompromised because of the disease and its treatments. This presents the question of their outcomes upon infection with SARS-CoV-2. Researchers assessed the characteristics of patients with lymphoma hospitalized for COVID-19 and analyzed determinants of mortality in a retrospective database study. The investigators looked at data from adult patients with lymphoma who were hospitalized for COVID-19 in March and April 2020 in three French regions.

Older age and relapsed/refractory (r/r) disease in B-cell lymphoma patients were both found to be independent risk factors of increased death rate from COVID-19, according to the online report in EClinicalMedicine, published by The Lancet.

These results encourage “the application of standard Covid-19 treatment, including intubation, for lymphoma patients with Covid-19 lymphoma diagnosis, under first- or second-line chemotherapy, or in remission,” according to Sylvain Lamure, MD, of Montellier (France) University, and colleagues.

The study examined a series of 89 consecutive patients from three French regions who had lymphoma and were hospitalized for COVID-19 in March and April 2020. The population was homogeneous; most patients were diagnosed with B-cell non-Hodgkin lymphoma (NHL) and had been treated for their lymphoma within 1 year.
 

Promising results for many

There were a significant associations between 30-day mortality and increasing age (over age 70 years) and r/r lymphoma. However, in the absence of those factors, mortality of the lymphoma patients with COVID-19 was comparable with that of the reference French COVID-19 population. In addition, there was no significant impact of active lymphoma treatment that had been given within 1 year, except for those patients who received bendamustine, which was associated with greater mortality, according to the researchers.

With a median follow-up of 33 days from admission, the Kaplan-Meier estimate of 30-day overall survival was 71% (95% confidence interval, 62%-81%). According to histological type of the lymphoma, 30-day overall survival rates were 80% (95% CI, 45%-100%) for Hodgkin lymphoma, 71% (95% CI, 61%-82%) for B-cell non-Hodgkin Lymphoma, and 71% (95% CI, 38%-100%) for T-cell non-Hodgkin Lymphoma.

The main factors associated with mortality were age 70 years and older (hazard ratio, 3.78; 95% CI, 1.73-8.25; P = .0009), hypertension (HR, 2.20; 95% CI, 1.06-4.59; P = .03), previous cancer (HR, 2.11; 95% CI, 0.90-4.92; P = .08), use of bendamustine within 12 months before admission to hospital (HR, 3.05; 95% CI, 1.31-7.11; P = .01), and r/r lymphoma (HR, 2.62; 95% CI, 1.20-5.72; P = .02).

Overall, the Kaplan-Meier estimates of 30-day overall survival were 61% for patients with r/r lymphoma, 52% in patients age 70 years with non–r/r lymphoma, and 88% for patients younger than 70 years with non–r/r, which was comparable with general population survival data among French populations, according to the researchers.

“Longer term clinical follow-up and biological monitoring of immune responses is warranted to explore the impact of lymphoma and its treatment on the immunity and prolonged outcome of Covid-19 patients,” they concluded.

The study was unsponsored. Several of the authors reported financial relationships with a number of biotechnology and pharmaceutical companies.

In the 1970s, cancer survival was poor for young children and older adults in the United States, as shown by data published in the Journal of the National Cancer Institute.

Great progress has been made since the 1970s, but improvements in outcome have been less impressive for cancer patients aged 15-39 years, as shown by research published in Cancer.

Factors that contribute to the AYA gap

About 89,000 AYAs are diagnosed with cancer each year in the United States, according to data from the National Cancer Institute (NCI). Lymphomas and thyroid cancer are the most common cancers among younger AYAs, aged 15-24 years.

In a report commissioned by the NIH in 2006, many factors contributing to the AYA gap were identified. Chief among them were:

• Limitations in access to care.
• Delayed diagnosis.
• Inconsistency in treatment and follow-up.
• Long-term toxicity (fertility, second malignancies, and cardiovascular disease).

These factors compromise health-related survival, even when cancer-specific survival is improved.

Panelist Kara Kelly, MD, of Roswell Park Comprehensive Cancer Center in Buffalo, N.Y., noted that there are additional unique challenges for AYAs with cancer. These include:

• Pubertal changes.
• Developmental transition to independence.
• Societal impediments such as insurance coverage and disparities in access to specialized centers.
• Psychosocial factors such as health literacy and adherence to treatment and follow-up.

Focusing on lymphoma specifically, Dr. Kelly noted that lymphoma biology differs across the age spectrum and by race and ethnicity. Both tumor and host factors require further study, she said.
 

Clinical trial access for AYAs

Dr. Kelly emphasized that, unfortunately, clinical research participation is low among AYAs. A major impediment is that adult clinical trials historically required participants to be at least 18 years old.

In addition, there has not been a focused effort to educate AYAs about regulatory safeguards to ensure safety and the promise of enhanced benefit to them in NCI Cancer Trials Network (NCTN) trials. As a result, the refusal rate is high.

A multi-stakeholder workshop, convened in May 2016 by the American Society of Clinical Oncology and Friends of Cancer Research, outlined opportunities for expanding trial eligibility to include children younger than 18 years in first-in-human and other adult cancer clinical trials, enhancing their access to new agents, without compromising safety.

Recently, collaborative efforts between the adult and children’s NCTN research groups have included AYAs in studies addressing cancers that span the age spectrum, including lymphoma.

However, as Dr. Kelly noted, there are differences in AYA lymphoid malignancy types with a transition from more pediatric to more adult types.
 

Hodgkin lymphoma and primary mediastinal B-cell lymphoma

Panelist Lisa G. Roth, MD, of Weill Cornell Medicine, New York, reviewed the genomic landscape of Hodgkin lymphoma (HL) and primary mediastinal B-cell lymphoma (PMBCL).

Dr. Roth explained that both HL and PMBCL are derived from thymic B cells, predominantly affect the mediastinum, and are CD30-positive lymphomas. Both are characterized by upregulation of JAK/STAT and NF-kappaB as well as overexpression of PD-L1.

Dr. Roth noted that HL is challenging to sequence by standard methods because Reed Sternberg (HRS) cells represent less than 1% of the cellular infiltrate. Recurrently mutated genes in HL cluster by histologic subtype.

Whole-exome sequencing of HRS cells show loss of beta-2 microglobulin and MHC-1 expression, HLA-B, NF-kappaB signaling, and JAK-STAT signaling, according to data published in Blood Advances in 2019.

Dr. Roth’s lab performed immunohistochemistry on tissue microarrays in 145 cases of HL (unpublished data). Results showed that loss of beta-2 microglobulin is more common in younger HL patients. For other alterations, there were too few cases to know.

Dr. Roth’s lab is a member of a pediatric/AYA HL sequencing multi-institutional consortium that has been able to extract DNA and RNA from samples submitted for whole-exome sequencing. The consortium’s goal is to shed light on implications of other genomic alterations that may differ by age in HL patients.

Dr. Roth cited research showing that PMBCL shares molecular alterations similar to those of HL. Alterations in PMBCL suggest dysregulated cellular signaling and immune evasion mechanisms (e.g., deletions in MHC type 1 and 2, beta-2 microglobulin, JAK-STAT, and NF-kappaB mutations) that provide opportunities to study novel agents, according to data published in Blood in 2019.

By early 2021, the S1826 and ANHL1931 studies, which have no age restriction, will be available to AYA lymphoma patients with HL and PMBCL, respectively, Dr. Roth said.
 

Follicular lymphoma: Clinical features by age

Panelist Abner Louissaint Jr, MD, PhD, of Massachusetts General Hospital in Boston, discussed age-related differences in follicular lymphoma (FL).

He noted that FL typically presents at an advanced stage, with low- or high-grade histology. It is increasingly common in adults in their 50s and 60s, representing 20% of all lymphomas. FL is rare in children and AYAs.

Dr. Louissaint explained that the typical flow cytometric findings in FL are BCL2 translocations, occurring in up to 85%-90% of low-grade and 50% of high-grade cases. The t(14;18)(q32;q21) translocation juxtaposes BCL2 on 18q21 to regulatory sequences and enhances the expression of elements of the Ig heavy chain.

Malignant cells in FL patients express CD20, CD10, CD21, and BCL2 (in contrast to normal germinal centers) and overexpress BCL6 (in contrast to normal follicles), Dr. Louissaint noted. He said the Ki-67 proliferative index of the malignant cells is typically low.

Pediatric-type FL is rare, but case series show clinical, pathologic, and molecular features that are distinctive from adult FL, Dr. Louissaint explained.

He then discussed the features of pediatric-type FL in multiple domains. In the clinical domain, there is a male predilection, and stage tends to be low. There is frequent involvement of nodes of the head and neck region and rare involvement of internal lymph node chains.

Pathologically, the malignant cells appear high grade, with architectural effacement, expansile follicular pattern, large lymphocyte size, and an elevated proliferation index. In contrast to adult FL, malignant cells in pediatric-type FL lack aberrant BCL2 expression.

Most importantly, for pediatric-type FL, the prognosis is excellent with durable remissions after surgical excision, Dr. Louissaint said.
 

Follicular lymphoma: Molecular features by age

Because of the excellent prognosis in pediatric-type FL, it is important to assess whether young adults with FL have adult-type or pediatric-type lesions, Dr. Louissaint said.

He cited many studies showing differences in adult and pediatric-type FL. In adult FL, the mutational landscape is characterized by frequent chromatin-modifying mutations in genes such as CREBBP, KM22D, and EP300.

In contrast, in pediatric-type FL, there are frequent activating MAPK pathway mutations, including mutations in the negative regulatory domain of MAP2K1. These mutations are not seen in adult FL.

Dr. Louissaint noted that there may be mutations in epigenetic modifiers (CREBBP, TNFRSF14) in both adult and pediatric-type FL. However, CREBBP is very unusual in pediatric-type FL and common in adult FL. This suggests the alterations in pediatric-type FL do not simply represent an early stage of the same disease as adult FL.

Despite a high proliferating fraction and absence of BCL2/BCL6/IRF4 rearrangements in pediatric-type FL, the presence of these features was associated with dramatic difference in progression-free survival, according to research published in Blood in 2012.
 

A distinct entity

In 2016, the World Health Organization recognized pediatric-type FL as a distinct entity, with the following diagnostic criteria (published in Blood):

• At least partial effacement of nodal architecture, expansile follicles, intermediate-size blastoid cells, and no component of diffuse large B-cell lymphoma.
• Immunohistochemistry showing BCL6 positivity, BCL2 negativity or weak positivity, and a high proliferative fraction.
• Genomic studies showing no BCL2 amplification.
• Clinical features of nodal disease in the head and neck region, early clinical stage, age younger than 40 years, typically in a male with no internal nodes involved.

When FL occurs in AYAs, the diagnostic findings of pediatric-type FL suggest the patient will do well with conservative management (e.g., excision alone), Dr. Louissaint noted.
 

Two sizes do not fit all

The strategies that have improved cancer outcomes since the 1970s for children and older adults have been much less successful for AYAs with cancer.

As an oncologic community, we should not allow the AYA gap to persist. As always, the solutions are likely to involve focused clinical research, education, and communication. Effort will need to be targeted specifically to the AYA population.

Since health-related mortality is high even when cancer-specific outcomes improve, adopting and maintaining a healthy lifestyle must be a key part of the discussion with these young patients.

The biologic differences associated with AYA lymphomas demand participation in clinical trials.

Oncologists should vigorously support removing impediments to the participation of AYAs in prospective clinical trials, stratified (but unrestricted) by age, with careful analysis of patient-reported outcomes, late adverse effects, and biospecimen collection.

As Dr. Kelly noted in the question-and-answer period, the Children’s Oncology Group has an existing biobank of paraffin-embedded tumor samples, DNA from lymphoma specimens, plasma, and sera with clinically annotated data that can be given to investigators upon request and justification.
 

Going beyond eligibility for clinical trials

Unfortunately, we will likely find that broadening eligibility criteria is the “low-hanging fruit.” There are protocol-, patient-, and physician-related obstacles, according to a review published in Cancer in 2019.

Patient-related obstacles include fear of toxicity, uncertainty about placebos, a steep learning curve for health literacy, insurance-related impediments, and other access-related issues.

Discussions will need to be tailored to the AYA population. Frank, early conversations about fertility, sexuality, financial hardship, career advancement, work-life balance, and cognitive risks may not only facilitate treatment planning but also encourage the trust that is essential for patients to enroll in trials.

The investment in time, multidisciplinary staff and physician involvement, and potential delays in treatment initiation may be painful and inconvenient, but the benefits for long-term health outcomes and personal-professional relationships will be gratifying beyond measure.

Dr. Smith disclosed relationships with Genentech/Roche, Celgene, TGTX, Karyopharm, Janssen, and Bantem. Dr. Roth disclosed relationships with Janssen, ADC Therapeutics, and Celgene. Dr. Kelly and Dr. Louissaint had no financial relationships to disclose.



Dr. Lyss was a community-based medical oncologist and clinical researcher for more than 35 years before his recent retirement. His clinical and research interests were focused on breast and lung cancers, as well as expanding clinical trial access to medically underserved populations. He is based in St. Louis. He has no conflicts of interest.

In the 1970s, cancer survival was poor for young children and older adults in the United States, as shown by data published in the Journal of the National Cancer Institute.

Great progress has been made since the 1970s, but improvements in outcome have been less impressive for cancer patients aged 15-39 years, as shown by research published in Cancer.

Pediatric-type FL is rare, but case series show clinical, pathologic, and molecular features that are distinctive from adult FL, Dr. Louissaint explained.

He then discussed the features of pediatric-type FL in multiple domains. In the clinical domain, there is a male predilection, and stage tends to be low. There is frequent involvement of nodes of the head and neck region and rare involvement of internal lymph node chains.

Pathologically, the malignant cells appear high grade, with architectural effacement, expansile follicular pattern, large lymphocyte size, and an elevated proliferation index. In contrast to adult FL, malignant cells in pediatric-type FL lack aberrant BCL2 expression.

Most importantly, for pediatric-type FL, the prognosis is excellent with durable remissions after surgical excision, Dr. Louissaint said.
 

Follicular lymphoma: Molecular features by age

Because of the excellent prognosis in pediatric-type FL, it is important to assess whether young adults with FL have adult-type or pediatric-type lesions, Dr. Louissaint said.

He cited many studies showing differences in adult and pediatric-type FL. In adult FL, the mutational landscape is characterized by frequent chromatin-modifying mutations in genes such as CREBBP, KM22D, and EP300.

In contrast, in pediatric-type FL, there are frequent activating MAPK pathway mutations, including mutations in the negative regulatory domain of MAP2K1. These mutations are not seen in adult FL.

Dr. Louissaint noted that there may be mutations in epigenetic modifiers (CREBBP, TNFRSF14) in both adult and pediatric-type FL. However, CREBBP is very unusual in pediatric-type FL and common in adult FL. This suggests the alterations in pediatric-type FL do not simply represent an early stage of the same disease as adult FL.

Despite a high proliferating fraction and absence of BCL2/BCL6/IRF4 rearrangements in pediatric-type FL, the presence of these features was associated with dramatic difference in progression-free survival, according to research published in Blood in 2012.
 

A distinct entity

In 2016, the World Health Organization recognized pediatric-type FL as a distinct entity, with the following diagnostic criteria (published in Blood):

• At least partial effacement of nodal architecture, expansile follicles, intermediate-size blastoid cells, and no component of diffuse large B-cell lymphoma.
• Immunohistochemistry showing BCL6 positivity, BCL2 negativity or weak positivity, and a high proliferative fraction.
• Genomic studies showing no BCL2 amplification.
• Clinical features of nodal disease in the head and neck region, early clinical stage, age younger than 40 years, typically in a male with no internal nodes involved.

When FL occurs in AYAs, the diagnostic findings of pediatric-type FL suggest the patient will do well with conservative management (e.g., excision alone), Dr. Louissaint noted.
 

Two sizes do not fit all

The strategies that have improved cancer outcomes since the 1970s for children and older adults have been much less successful for AYAs with cancer.

As an oncologic community, we should not allow the AYA gap to persist. As always, the solutions are likely to involve focused clinical research, education, and communication. Effort will need to be targeted specifically to the AYA population.

Since health-related mortality is high even when cancer-specific outcomes improve, adopting and maintaining a healthy lifestyle must be a key part of the discussion with these young patients.

The biologic differences associated with AYA lymphomas demand participation in clinical trials.

Oncologists should vigorously support removing impediments to the participation of AYAs in prospective clinical trials, stratified (but unrestricted) by age, with careful analysis of patient-reported outcomes, late adverse effects, and biospecimen collection.

As Dr. Kelly noted in the question-and-answer period, the Children’s Oncology Group has an existing biobank of paraffin-embedded tumor samples, DNA from lymphoma specimens, plasma, and sera with clinically annotated data that can be given to investigators upon request and justification.
 

Going beyond eligibility for clinical trials

Unfortunately, we will likely find that broadening eligibility criteria is the “low-hanging fruit.” There are protocol-, patient-, and physician-related obstacles, according to a review published in Cancer in 2019.

Patient-related obstacles include fear of toxicity, uncertainty about placebos, a steep learning curve for health literacy, insurance-related impediments, and other access-related issues.

Discussions will need to be tailored to the AYA population. Frank, early conversations about fertility, sexuality, financial hardship, career advancement, work-life balance, and cognitive risks may not only facilitate treatment planning but also encourage the trust that is essential for patients to enroll in trials.

The investment in time, multidisciplinary staff and physician involvement, and potential delays in treatment initiation may be painful and inconvenient, but the benefits for long-term health outcomes and personal-professional relationships will be gratifying beyond measure.

Dr. Smith disclosed relationships with Genentech/Roche, Celgene, TGTX, Karyopharm, Janssen, and Bantem. Dr. Roth disclosed relationships with Janssen, ADC Therapeutics, and Celgene. Dr. Kelly and Dr. Louissaint had no financial relationships to disclose.



Dr. Lyss was a community-based medical oncologist and clinical researcher for more than 35 years before his recent retirement. His clinical and research interests were focused on breast and lung cancers, as well as expanding clinical trial access to medically underserved populations. He is based in St. Louis. He has no conflicts of interest.

In the 1970s, cancer survival was poor for young children and older adults in the United States, as shown by data published in the Journal of the National Cancer Institute.

Great progress has been made since the 1970s, but improvements in outcome have been less impressive for cancer patients aged 15-39 years, as shown by research published in Cancer.

Factors that contribute to the AYA gap

About 89,000 AYAs are diagnosed with cancer each year in the United States, according to data from the National Cancer Institute (NCI). Lymphomas and thyroid cancer are the most common cancers among younger AYAs, aged 15-24 years.

In a report commissioned by the NIH in 2006, many factors contributing to the AYA gap were identified. Chief among them were:

• Limitations in access to care.
• Delayed diagnosis.
• Inconsistency in treatment and follow-up.
• Long-term toxicity (fertility, second malignancies, and cardiovascular disease).

These factors compromise health-related survival, even when cancer-specific survival is improved.

Panelist Kara Kelly, MD, of Roswell Park Comprehensive Cancer Center in Buffalo, N.Y., noted that there are additional unique challenges for AYAs with cancer. These include:

• Pubertal changes.
• Developmental transition to independence.
• Societal impediments such as insurance coverage and disparities in access to specialized centers.
• Psychosocial factors such as health literacy and adherence to treatment and follow-up.

Focusing on lymphoma specifically, Dr. Kelly noted that lymphoma biology differs across the age spectrum and by race and ethnicity. Both tumor and host factors require further study, she said.
 

Clinical trial access for AYAs

Dr. Kelly emphasized that, unfortunately, clinical research participation is low among AYAs. A major impediment is that adult clinical trials historically required participants to be at least 18 years old.

In addition, there has not been a focused effort to educate AYAs about regulatory safeguards to ensure safety and the promise of enhanced benefit to them in NCI Cancer Trials Network (NCTN) trials. As a result, the refusal rate is high.

A multi-stakeholder workshop, convened in May 2016 by the American Society of Clinical Oncology and Friends of Cancer Research, outlined opportunities for expanding trial eligibility to include children younger than 18 years in first-in-human and other adult cancer clinical trials, enhancing their access to new agents, without compromising safety.

Recently, collaborative efforts between the adult and children’s NCTN research groups have included AYAs in studies addressing cancers that span the age spectrum, including lymphoma.

However, as Dr. Kelly noted, there are differences in AYA lymphoid malignancy types with a transition from more pediatric to more adult types.
 

Hodgkin lymphoma and primary mediastinal B-cell lymphoma

Panelist Lisa G. Roth, MD, of Weill Cornell Medicine, New York, reviewed the genomic landscape of Hodgkin lymphoma (HL) and primary mediastinal B-cell lymphoma (PMBCL).

Dr. Roth explained that both HL and PMBCL are derived from thymic B cells, predominantly affect the mediastinum, and are CD30-positive lymphomas. Both are characterized by upregulation of JAK/STAT and NF-kappaB as well as overexpression of PD-L1.

Dr. Roth noted that HL is challenging to sequence by standard methods because Reed Sternberg (HRS) cells represent less than 1% of the cellular infiltrate. Recurrently mutated genes in HL cluster by histologic subtype.

Whole-exome sequencing of HRS cells show loss of beta-2 microglobulin and MHC-1 expression, HLA-B, NF-kappaB signaling, and JAK-STAT signaling, according to data published in Blood Advances in 2019.

Dr. Roth’s lab performed immunohistochemistry on tissue microarrays in 145 cases of HL (unpublished data). Results showed that loss of beta-2 microglobulin is more common in younger HL patients. For other alterations, there were too few cases to know.

Dr. Roth’s lab is a member of a pediatric/AYA HL sequencing multi-institutional consortium that has been able to extract DNA and RNA from samples submitted for whole-exome sequencing. The consortium’s goal is to shed light on implications of other genomic alterations that may differ by age in HL patients.

Dr. Roth cited research showing that PMBCL shares molecular alterations similar to those of HL. Alterations in PMBCL suggest dysregulated cellular signaling and immune evasion mechanisms (e.g., deletions in MHC type 1 and 2, beta-2 microglobulin, JAK-STAT, and NF-kappaB mutations) that provide opportunities to study novel agents, according to data published in Blood in 2019.

By early 2021, the S1826 and ANHL1931 studies, which have no age restriction, will be available to AYA lymphoma patients with HL and PMBCL, respectively, Dr. Roth said.
 

Follicular lymphoma: Clinical features by age

Panelist Abner Louissaint Jr, MD, PhD, of Massachusetts General Hospital in Boston, discussed age-related differences in follicular lymphoma (FL).

He noted that FL typically presents at an advanced stage, with low- or high-grade histology. It is increasingly common in adults in their 50s and 60s, representing 20% of all lymphomas. FL is rare in children and AYAs.

Dr. Louissaint explained that the typical flow cytometric findings in FL are BCL2 translocations, occurring in up to 85%-90% of low-grade and 50% of high-grade cases. The t(14;18)(q32;q21) translocation juxtaposes BCL2 on 18q21 to regulatory sequences and enhances the expression of elements of the Ig heavy chain.

Malignant cells in FL patients express CD20, CD10, CD21, and BCL2 (in contrast to normal germinal centers) and overexpress BCL6 (in contrast to normal follicles), Dr. Louissaint noted. He said the Ki-67 proliferative index of the malignant cells is typically low.

His clinical and research interests were focused on breast and lung cancers, as well as expanding clinical trial access to medically underserved populations. He is based in St. Louis. He has no conflicts of interest.

When the first reports emerged of “cytokine storm” in patients with severe COVID-19, all eyes turned to cancer research. Oncologists have years of experience reigning in “cytokine release syndrome” (CRS) in patients treated with chimeric antigen receptor (CAR) therapies for advanced blood cancers.

There was hope that drugs used to quell CRS in patients with cancer would be effective in patients with severe COVID. But the promise of a quick fix with oncology medications has yet to be fully realized.

Part of the problem is that the two conditions, while analogous, are “not the same,” said Nirali Shah, MD, head of the hematologic malignancies section in the pediatric oncology branch at the National Cancer Institute.

“You have to understand the underlying pathophysiology, what triggers the inflammation,” Dr. Shah said.

CAR T–related CRS is caused by activated T cells in patients with cancer who often do not have an infection, she explained. In contrast, cytokine storm in COVID-19 is triggered by a viral pathogen that can drive “out of control” inflammation. These differences may explain why drugs work in the first instance, but not in the second, she added. Drugs that inhibit interleukin-6 (such as tocilizumab, sarilumab, and siltuximab) are used with great success to dampen down the CRS in patients receiving CAR therapy for blood cancers. And although trials of these agents in patients with COVID are still ongoing, initial results are disappointing.

The first global, phase 3 randomized controlled trial of tocilizumab in severe COVID-19 failed to meet its primary endpoint of improved clinical status, and it did not meet its secondary endpoint of improved mortality at week 4.

In its recent recommendations, the National Institutes of Health noted a lack of data to support the efficacy of IL-6 inhibitors in COVID-19, and recommended against their use, except as part of a clinical trial.
 

Trimming the tree vs. cutting it down

As researchers have begun to decode the immune process underlying severe COVID-19, they have turned to other cancer drugs to tame cytokine storm.

Louis Staudt, MD, PhD, and Wyndham Wilson, MD, PhD, both at the NCI, think that cytokine storm in COVID-19 is driven by macrophages, which trigger release of multiple cytokines.

For years, the pair have been studying lymphoid tumors. Dr. Staudt is chief of the lymphoid malignancies branch at the NCI, and Wilson is head of the lymphoma therapeutics section. In past work, Dr. Staudt discovered that inhibiting an enzyme called bruton tyrosine kinase (BTK) dampens macrophage function.

When the pandemic began, Dr. Staudt and Dr. Wilson realized that singling out just one cytokine like IL-6 may not be enough. They thought that a more effective approach may be to target macrophages with a BTK inhibitor called acalabrutinib (Calquence), which would inhibit multiple cytokines at the same time.

Dr. Staudt likens the immune response to a tree, with the macrophages composing the tree trunk and the limbs made up of individual cytokines.

“Targeting macrophages is getting at the trunk of the problem,” he said. “You’re only cutting off the limbs with tocilizumab.”

In just 3 days, Dr. Staudt and Dr. Wilson went from concept to approval to launching a prospective, observational study. The study took place at five centers in the US, and included 19 patients hospitalized with COVID-19; the results were published in Science Immunology. Over a treatment course of 14 days, the majority of patients treated off-label with acalabrutinib improved, some within 24 hours. Eight of 11 patients on supplemental oxygen were discharged on room air. Four of eight patients on ventilators were extubated, with two of these discharged on room air. Two patients on ventilators died. No discernible toxicity was noted.

Analyses also showed increased BTK activity and elevated IL-6 levels in monocytes – precursors of macrophages – in patients with severe COVID-19, compared with healthy volunteers.

“We showed that the target of acalabrutinib was active in the immune cells of patients with severe COVID-19,” Dr. Staudt said. “So we have the target. We have the drug to hit the target. And we have an apparent clinical benefit.”

Those three things were compelling enough to launch the CALAVI phase 2 trial, an open-label, randomized, controlled trial, sponsored by AstraZeneca and the NCI, that is being conducted in the United States and internationally. It is testing acalabrutinib with best supportive care versus BSC alone in people hospitalized with COVID-19. The trial is scheduled to be completed on Nov. 26.

Preliminary insights from this trial are expected soon. “These are not insights that we will likely publish, but they are important insights that will lead to the launch of a definitive double-blind, randomized, phase 3 trial, which we hope to launch in the next month or so,” Dr. Wilson said.
 

Targeting inflammation and infection simultaneously

Other scientists are investigating inhibitors of Janus kinase (JAK), a family of enzymes that play a key role in orchestrating immune responses, particularly cytokines. Interest in JAK inhibition to control hyperinflammation in cancer goes back at least 15 years, and drugs that act as JAK inhibitors are already approved for use in the treatment of myelofibrosis (ruxolitinib [Jakafi], fedratinib [Inrebic]) and also for rheumatoid arthritis (upadacitinib [Rinvoq], baricitinib [Olumiant]).

“It wasn’t a huge leap for those of us with a lot of understanding of JAK inhibitors to propose taking them into the clinic to treat patients with COVID-19,” commented John Mascarenhas, MD, the leader of clinical investigation in the myeloproliferative disorders program at the Icahn School of Medicine at Mount Sinai, New York.

Dr. Mascarenhas is also principal investigator of the PRE-VENT trial, which is comparing the investigational JAK2 inhibitor pacritinib plus standard of care to standard of care alone in patients hospitalized with severe COVID-19, with and without cancer. The trial is sponsored by CTI BioPharma (manufacturer of pacritinib), and is taking place at 10 sites in the United States.

In a move that may raise eyebrows, PRE-VENT skipped phase 1 and 2 and went straight to phase 3. Pacritinib has yet to receive FDA approval and has mostly been studied in myelofibrosis, an intensely inflammatory disease.

The decision was based on trials of pacritinib in hematologic malignancies and also on results from a phase 2 study in China that found possible clinical benefit for the JAK 1/2 inhibitor ruxolitinib in 43 patients hospitalized with severe COVID-19, although results were not statistically significant, Dr. Mascarenhas explained.

Recent results from Lilly’s ACTT-2 study have provided further support for the role of JAK inhibitors in treating cytokine storm. ACTT-2 is a phase 3, double-blind, placebo-controlled, randomized, controlled trial sponsored by the NIH and NIAID comparing the JAK 1/2 inhibitor baricitinib plus the antiviral remdesivir with remdesivir alone in patients hospitalized with COVID-19. In September, Lilly announced that the trial met its primary endpoint of decreased time to recovery in patients who received baricitinib in combination with remdesivir.

But pacritinib’s mechanism of action may take things a step further. The drug selectively inhibits JAK2 and spares JAK1, which is important for antiviral activity in the immune system. Also, in vitro data suggests pacritinib may simultaneously reduce inflammation and fight off the virus by selectively inhibiting two additional enzymes and two other receptors.

“The rationale to me is very strong for using pacritinib,” Dr. Mascarenhas said. “I think this approach was bold but appropriate.”

The main safety concern with pacritinib could be bleeding, especially among patients on anticoagulants, Dr. Mascarenhas said. Because some patients with severe COVID-19 tend to develop blood clots, anticoagulation has become the standard of care at many institutions.

Because the trial is just beginning – only a minority of the total planned population of 358 patients has been enrolled – no interim results are available.
 

Right drug, wrong time?

IL-6 inhibition could still have a role to play in COVID-19, but the trick could be in the timing. Most of the trials so far have studied tocilizumab in patients with severe COVID-19, many of whom were already on ventilators. At that point, it may be too late to reverse the damage that has already taken place.

One of the main reasons tocilizumab works so well in CRS after CAR T therapy is that oncologists have learned how to use it early, often within 24 hours of fever onset. Oncologists use the American Society for Transplantation and Cellular Therapy consensus grading system, which helps them identify CRS when it is easier to control.

But applying the ASTCT grading system to COVID-19 is problematic. “Almost by definition, patients hospitalized with COVID-19 have low oxygen levels, which throws off the scale,” said Joshua Hill, MD, an infectious disease specialist at Fred Hutchinson Cancer Research Center in Seattle, who has research expertise in infectious complications after CAR T therapy.

“The key is to intervene earlier to prevent damage to the lungs and other end organs. We don’t have anything magical that will reverse that damage,” Dr. Hill said.

Results from the phase 3 trial EMPACTA trial (sponsored by Genentech) seem to bear this out. EMPACTA is evaluating use of tocilizumab in hospitalized patients with less severe COVID-19 who do not yet require mechanical ventilation. The trial is notable for being the first global phase 3 trial to demonstrate efficacy for tocilizumab vs placebo in hospitalized patients with COVID-19 pneumonia, and for including a high percentage of racial/ethnic minorities (85% of 389 participants), who have been hard hit by the pandemic and have historically been underrepresented in drug trials.

Last month, Roche announced that EMPACTA met its primary endpoint. Results showed that patients hospitalized with COVID-19 pneumonia who received tocilizumab plus standard of care were 44% less likely to go on mechanical ventilation or die, compared with those who received placebo plus standard of care (P = .0348), although there were no statistically significant differences in death by day 28 between tocilizumab and placebo (10.4% vs. 8.6%, P = .5146).

However, earlier administration of tocilizumab raises another issue. IL-6 and its pathway are important for clearing viral infections. Using tocilizumab in the context of an ongoing infection could raise safety issues.

Also, tocilizumab sticks around in the body for a relatively long time. In the treatment of rheumatoid arthritis, it is dosed once a month, and it carries a black box warning for reactivation of tuberculosis.

Whereas results from EMPACTA showed similar rates of infection associated with tocilizumab and placebo (10% vs. 11%), at least one other study has found increased rates of superinfection in patients with severe COVID-19 who received tocilizumab. Overall, though, the drug was associated with decreased risk of death in the latter study.

A phase 2 trial called COVIDOSE is tackling the safety issue. COVIDOSE is evaluating whether low-dose tocilizumab is effective in noncritical COVID-19 patients, with the idea that lower doses could be safer. Early results published as a preprint before peer review indicated that low-dose tocilizumab (ranging from 40 mg to 200 mg) was associated with clinical improvement in 32 noncritical patients hospitalized with COVID-19.

Five patients (15.6%) developed bacterial superinfections, and five (15.6%) died by 28-day follow-up, although there wasn’t a perfect “overlap” between these groups of patients. Bacterial superinfection was not the cause of death in all five patients who died, and not all patients who died developed bacterial superinfections, according to senior author Pankti Reid, MD, MPH, an assistant professor of medicine at the University of Chicago.

Results from COVIDOSE also showed that treatment with tocilizumab did not seem to affect the ability of patients to develop antibodies against COVID-19. The results set the stage for a larger randomized, controlled trial (still ongoing) to determine the optimal dose of tocilizumab.

Still, Dr. Hill urges caution.

Many of these immunomodulators have been used only in the context of a clinical trial, or only for patients with terminal cancer and no other treatment options. In patients with cancer, these drugs have been studied and have shown an “acceptable safety profile,” according to Dr. Shah.

But this is a different situation, and when it comes to repurposing them to relatively healthy patients with COVID-19, Dr. Hill emphasized the need for careful research.

“We’re always very concerned about giving drugs that suppress the immune response if people have active infections,” Dr. Hill said. “Often times we think it makes things worse, and it typically does.”

Dr. Mascarenhas reported institutional research funding from CTI Biopharma. Dr. Hill, Dr. Staudt, Dr. Wilson, and Dr. Shah disclosed no relevant financial relationships.

“It wasn’t a huge leap for those of us with a lot of understanding of JAK inhibitors to propose taking them into the clinic to treat patients with COVID-19,” commented John Mascarenhas, MD, the leader of clinical investigation in the myeloproliferative disorders program at the Icahn School of Medicine at Mount Sinai, New York.

Dr. Mascarenhas is also principal investigator of the PRE-VENT trial, which is comparing the investigational JAK2 inhibitor pacritinib plus standard of care to standard of care alone in patients hospitalized with severe COVID-19, with and without cancer. The trial is sponsored by CTI BioPharma (manufacturer of pacritinib), and is taking place at 10 sites in the United States.

In a move that may raise eyebrows, PRE-VENT skipped phase 1 and 2 and went straight to phase 3. Pacritinib has yet to receive FDA approval and has mostly been studied in myelofibrosis, an intensely inflammatory disease.

The decision was based on trials of pacritinib in hematologic malignancies and also on results from a phase 2 study in China that found possible clinical benefit for the JAK 1/2 inhibitor ruxolitinib in 43 patients hospitalized with severe COVID-19, although results were not statistically significant, Dr. Mascarenhas explained.

Recent results from Lilly’s ACTT-2 study have provided further support for the role of JAK inhibitors in treating cytokine storm. ACTT-2 is a phase 3, double-blind, placebo-controlled, randomized, controlled trial sponsored by the NIH and NIAID comparing the JAK 1/2 inhibitor baricitinib plus the antiviral remdesivir with remdesivir alone in patients hospitalized with COVID-19. In September, Lilly announced that the trial met its primary endpoint of decreased time to recovery in patients who received baricitinib in combination with remdesivir.

But pacritinib’s mechanism of action may take things a step further. The drug selectively inhibits JAK2 and spares JAK1, which is important for antiviral activity in the immune system. Also, in vitro data suggests pacritinib may simultaneously reduce inflammation and fight off the virus by selectively inhibiting two additional enzymes and two other receptors.

“The rationale to me is very strong for using pacritinib,” Dr. Mascarenhas said. “I think this approach was bold but appropriate.”

The main safety concern with pacritinib could be bleeding, especially among patients on anticoagulants, Dr. Mascarenhas said. Because some patients with severe COVID-19 tend to develop blood clots, anticoagulation has become the standard of care at many institutions.

Because the trial is just beginning – only a minority of the total planned population of 358 patients has been enrolled – no interim results are available.
 

Right drug, wrong time?

IL-6 inhibition could still have a role to play in COVID-19, but the trick could be in the timing. Most of the trials so far have studied tocilizumab in patients with severe COVID-19, many of whom were already on ventilators. At that point, it may be too late to reverse the damage that has already taken place.

One of the main reasons tocilizumab works so well in CRS after CAR T therapy is that oncologists have learned how to use it early, often within 24 hours of fever onset. Oncologists use the American Society for Transplantation and Cellular Therapy consensus grading system, which helps them identify CRS when it is easier to control.

But applying the ASTCT grading system to COVID-19 is problematic. “Almost by definition, patients hospitalized with COVID-19 have low oxygen levels, which throws off the scale,” said Joshua Hill, MD, an infectious disease specialist at Fred Hutchinson Cancer Research Center in Seattle, who has research expertise in infectious complications after CAR T therapy.

“The key is to intervene earlier to prevent damage to the lungs and other end organs. We don’t have anything magical that will reverse that damage,” Dr. Hill said.

Results from the phase 3 trial EMPACTA trial (sponsored by Genentech) seem to bear this out. EMPACTA is evaluating use of tocilizumab in hospitalized patients with less severe COVID-19 who do not yet require mechanical ventilation. The trial is notable for being the first global phase 3 trial to demonstrate efficacy for tocilizumab vs placebo in hospitalized patients with COVID-19 pneumonia, and for including a high percentage of racial/ethnic minorities (85% of 389 participants), who have been hard hit by the pandemic and have historically been underrepresented in drug trials.

Last month, Roche announced that EMPACTA met its primary endpoint. Results showed that patients hospitalized with COVID-19 pneumonia who received tocilizumab plus standard of care were 44% less likely to go on mechanical ventilation or die, compared with those who received placebo plus standard of care (P = .0348), although there were no statistically significant differences in death by day 28 between tocilizumab and placebo (10.4% vs. 8.6%, P = .5146).

However, earlier administration of tocilizumab raises another issue. IL-6 and its pathway are important for clearing viral infections. Using tocilizumab in the context of an ongoing infection could raise safety issues.

Also, tocilizumab sticks around in the body for a relatively long time. In the treatment of rheumatoid arthritis, it is dosed once a month, and it carries a black box warning for reactivation of tuberculosis.

Whereas results from EMPACTA showed similar rates of infection associated with tocilizumab and placebo (10% vs. 11%), at least one other study has found increased rates of superinfection in patients with severe COVID-19 who received tocilizumab. Overall, though, the drug was associated with decreased risk of death in the latter study.

A phase 2 trial called COVIDOSE is tackling the safety issue. COVIDOSE is evaluating whether low-dose tocilizumab is effective in noncritical COVID-19 patients, with the idea that lower doses could be safer. Early results published as a preprint before peer review indicated that low-dose tocilizumab (ranging from 40 mg to 200 mg) was associated with clinical improvement in 32 noncritical patients hospitalized with COVID-19.

Five patients (15.6%) developed bacterial superinfections, and five (15.6%) died by 28-day follow-up, although there wasn’t a perfect “overlap” between these groups of patients. Bacterial superinfection was not the cause of death in all five patients who died, and not all patients who died developed bacterial superinfections, according to senior author Pankti Reid, MD, MPH, an assistant professor of medicine at the University of Chicago.

Results from COVIDOSE also showed that treatment with tocilizumab did not seem to affect the ability of patients to develop antibodies against COVID-19. The results set the stage for a larger randomized, controlled trial (still ongoing) to determine the optimal dose of tocilizumab.

Still, Dr. Hill urges caution.

Many of these immunomodulators have been used only in the context of a clinical trial, or only for patients with terminal cancer and no other treatment options. In patients with cancer, these drugs have been studied and have shown an “acceptable safety profile,” according to Dr. Shah.

But this is a different situation, and when it comes to repurposing them to relatively healthy patients with COVID-19, Dr. Hill emphasized the need for careful research.

“We’re always very concerned about giving drugs that suppress the immune response if people have active infections,” Dr. Hill said. “Often times we think it makes things worse, and it typically does.”

Dr. Mascarenhas reported institutional research funding from CTI Biopharma. Dr. Hill, Dr. Staudt, Dr. Wilson, and Dr. Shah disclosed no relevant financial relationships.

When the first reports emerged of “cytokine storm” in patients with severe COVID-19, all eyes turned to cancer research. Oncologists have years of experience reigning in “cytokine release syndrome” (CRS) in patients treated with chimeric antigen receptor (CAR) therapies for advanced blood cancers.

There was hope that drugs used to quell CRS in patients with cancer would be effective in patients with severe COVID. But the promise of a quick fix with oncology medications has yet to be fully realized.

Part of the problem is that the two conditions, while analogous, are “not the same,” said Nirali Shah, MD, head of the hematologic malignancies section in the pediatric oncology branch at the National Cancer Institute.

“You have to understand the underlying pathophysiology, what triggers the inflammation,” Dr. Shah said.

CAR T–related CRS is caused by activated T cells in patients with cancer who often do not have an infection, she explained. In contrast, cytokine storm in COVID-19 is triggered by a viral pathogen that can drive “out of control” inflammation. These differences may explain why drugs work in the first instance, but not in the second, she added. Drugs that inhibit interleukin-6 (such as tocilizumab, sarilumab, and siltuximab) are used with great success to dampen down the CRS in patients receiving CAR therapy for blood cancers. And although trials of these agents in patients with COVID are still ongoing, initial results are disappointing.

The first global, phase 3 randomized controlled trial of tocilizumab in severe COVID-19 failed to meet its primary endpoint of improved clinical status, and it did not meet its secondary endpoint of improved mortality at week 4.

In its recent recommendations, the National Institutes of Health noted a lack of data to support the efficacy of IL-6 inhibitors in COVID-19, and recommended against their use, except as part of a clinical trial.
 

Trimming the tree vs. cutting it down

As researchers have begun to decode the immune process underlying severe COVID-19, they have turned to other cancer drugs to tame cytokine storm.

Louis Staudt, MD, PhD, and Wyndham Wilson, MD, PhD, both at the NCI, think that cytokine storm in COVID-19 is driven by macrophages, which trigger release of multiple cytokines.

For years, the pair have been studying lymphoid tumors. Dr. Staudt is chief of the lymphoid malignancies branch at the NCI, and Wilson is head of the lymphoma therapeutics section. In past work, Dr. Staudt discovered that inhibiting an enzyme called bruton tyrosine kinase (BTK) dampens macrophage function.

When the pandemic began, Dr. Staudt and Dr. Wilson realized that singling out just one cytokine like IL-6 may not be enough. They thought that a more effective approach may be to target macrophages with a BTK inhibitor called acalabrutinib (Calquence), which would inhibit multiple cytokines at the same time.

Dr. Staudt likens the immune response to a tree, with the macrophages composing the tree trunk and the limbs made up of individual cytokines.

“Targeting macrophages is getting at the trunk of the problem,” he said. “You’re only cutting off the limbs with tocilizumab.”

In just 3 days, Dr. Staudt and Dr. Wilson went from concept to approval to launching a prospective, observational study. The study took place at five centers in the US, and included 19 patients hospitalized with COVID-19; the results were published in Science Immunology. Over a treatment course of 14 days, the majority of patients treated off-label with acalabrutinib improved, some within 24 hours. Eight of 11 patients on supplemental oxygen were discharged on room air. Four of eight patients on ventilators were extubated, with two of these discharged on room air. Two patients on ventilators died. No discernible toxicity was noted.

Analyses also showed increased BTK activity and elevated IL-6 levels in monocytes – precursors of macrophages – in patients with severe COVID-19, compared with healthy volunteers.

“We showed that the target of acalabrutinib was active in the immune cells of patients with severe COVID-19,” Dr. Staudt said. “So we have the target. We have the drug to hit the target. And we have an apparent clinical benefit.”

Those three things were compelling enough to launch the CALAVI phase 2 trial, an open-label, randomized, controlled trial, sponsored by AstraZeneca and the NCI, that is being conducted in the United States and internationally. It is testing acalabrutinib with best supportive care versus BSC alone in people hospitalized with COVID-19. The trial is scheduled to be completed on Nov. 26.

Preliminary insights from this trial are expected soon. “These are not insights that we will likely publish, but they are important insights that will lead to the launch of a definitive double-blind, randomized, phase 3 trial, which we hope to launch in the next month or so,” Dr. Wilson said.
 

Targeting inflammation and infection simultaneously

Other scientists are investigating inhibitors of Janus kinase (JAK), a family of enzymes that play a key role in orchestrating immune responses, particularly cytokines. Interest in JAK inhibition to control hyperinflammation in cancer goes back at least 15 years, and drugs that act as JAK inhibitors are already approved for use in the treatment of myelofibrosis (ruxolitinib [Jakafi], fedratinib [Inrebic]) and also for rheumatoid arthritis (upadacitinib [Rinvoq], baricitinib [Olumiant]).
