Hodgkin Lymphoma

Lymphomas appear to be up to four times more likely in patients with hidradenitis suppurativa than among the general population, Rachel Tannenbaum and her colleagues reported in a Research Letter in JAMA Dermatology.

The risks of Hodgkin (HL), non-Hodgkin (NHL), and cutaneous T-cell lymphoma (CTCL) all were significantly higher among patients with HS, wrote Ms. Tannenbaum, Andrew Strunk, and Amit Garg, MD. Males and older patients carried higher risks than females and younger patients, they found.

The team members, of Hofstra University, Hempstead, N.Y., conducted a health care database study comprising 55 million patients included in 27 integrated U.S. health care systems. All the subjects were at least 18 years old; records indicated active HS during the study period of 2013-2018. A regression analysis controlled for age and sex.

The database contained 62,690 patients with HS. The majority (74%) were female and were aged 44 years or younger (57%).

All three lymphomas were more common among HS patients than patients without HS, including non-Hodgkin lymphoma (0.40% vs. 0.35%,) Hodgkin lymphoma (0.17% vs. 0.09%), and cutaneous T-cell lymphoma (0.06% vs. 0.02%).

The multivariate analysis determined that HS patients were twice as likely to develop both non-Hodgkin and Hodgkin lymphoma (odds ratio, 2.0 and 2.21, respectively). They were four times more likely to develop cutaneous T-cell lymphoma (OR, 4.31).

All three lymphomas were more common among males than females: NHL, 0.62% vs. 0.32%; HL, 0.28% vs. 0.13%; and CTCL, 0.09% vs. 0.04%. This translated into significantly increased HS-associated risks, Ms. Tannenbaum and her coauthors noted. “For example, the [odds ratios] for the association between HS and HL were higher in males (OR, 2.97; 95% confidence interval, 2.22-3.99) than in females (OR, 1.86; 95% CI, 1.44-2.39) (P = .02),” they wrote.

Lymphomas were more common among HS patients in every age group. Those aged 18-44 years were 3.64 times more likely to develop NHL than those without HS. Patients with HS aged 45-64 years were 38% more likely to develop NHL, and those older than 65, about twice as likely (OR, 1.99).

“To our knowledge, this is the first investigation to systematically evaluate this association in a U.S. population of patients with HS,” the research team concluded.

The study was supported by a grant from AbbVie. Ms. Tannenbaum and Mr. Strunk reported no disclosures. Dr. Garg reported financial relationships with AbbVie and several other pharmaceutical companies.

Combined modality therapy (CMT) can improve survival in young patients with early stage Hodgkin lymphoma (HL), according to research published in JAMA Oncology.

In a retrospective study, researchers compared chemotherapy followed by radiotherapy—CMT—to chemotherapy alone in more than 5,600 HL patients age 21 and younger.

There was a significant improvement in 5-year overall survival (OS) among patients who received CMT.

The treatment appeared particularly beneficial for adolescents and young adults as well as patients with low-risk disease.

However, the researchers observed a nearly 25% decrease in the use of CMT over the period studied.

“Nationwide, there has been a notable decrease in combined modality therapy, especially in clinical trials, many of which are designed to avoid this strategy,” said Rahul Parikh, MD, of Rutgers Cancer Institute of New Jersey in New Brunswick.

“This form of treatment has shown to be effective, with event-free survival rates greater than 80% and overall survival rates greater than 95%. The question then becomes, ‘does treatment benefit outweigh the risk of long-term side effects?”

With this in mind, Dr. Parikh and his colleagues compared CMT to chemotherapy alone using data from the National Cancer Database spanning the period from 2004 to 2015.

The researchers analyzed 5,657 patients with stage I/II classical HL who had a mean age of 17.1.

Roughly half of patients received CMT (50.3%, n=2845), and the other half received chemotherapy alone (49.7%, n=2812).

The median radiotherapy dose was 21.0 Gy, and the most common modality was photon therapy (59.0%).

Patients who received CMT were significantly more likely to be younger than 16 (P<0.001), be male (P<0.001), have stage II disease (P=0.02), and have private health insurance (P=0.002).

Results

The median follow-up was 5.1 years.

The 5-year OS was 94.5% for patients who received chemotherapy alone and 97.3% for patients treated with CMT.

CMT was significantly associated with improved OS in both univariate (hazard ratio [HR]=0.58, P<0.001) and multivariate analyses (HR=0.57, P<0.001).

In a sensitivity analysis, the researchers found the greatest benefits of CMT were in adolescents and young adults (age 14 and older, adjusted HR=0.47) and patients with low-risk disease (stage I-IIA, adjusted HR=0.59).

The researchers noted that this study was limited by their inability to control for unreported prognostic factors, such as the number of nodal sites and bulk of disease.

Another limitation was the duration of follow-up, which did not allow the researchers to fully assess secondary late effects of CMT and their potential impact on survival.

Still, Dr. Parikh said this study demonstrates a survival benefit for young HL patients treated with CMT.

“With that, physicians should be encouraged to discuss combined modality therapy as one of the many treatment options [for young HL patients],” he said.

“Investigators may also consider designing future clinical trials for this population to include combined modality therapy as a standard arm with the inclusion of interim treatment response assessment (PET scans, etc.). And as multiple disparities to the use of combined modality therapy have been identified through this work, future studies should address improving access to care for all pediatric patients.”

Dr. Parikh and his colleagues declared no conflicts of interest for the current study.

Survivors of childhood Hodgkin lymphoma (HL) have a 14-fold higher risk of second cancers compared to the general population, according to new research.

The subsequent malignant neoplasms (SMNs) observed in HL survivors tended to follow specific patterns depending on the patient’s age at treatment, sex, treatment modality, and region of the body treated.

And although the risk of SMNs appears to be somewhat lower for HL patients treated in more recent decades, it is still significantly higher than the risk in the general population, according to investigators.

Anna S. Holmqvist, MD, PhD, of the University of Lund in Sweden, and her colleagues conducted this research and reported the results in Cancer.

The investigators looked at data from the Late Effects Study Group, a multinational cohort of patients age 16 or younger who were treated for HL and other cancers from 1955 through 1986.

The current report is the third update from an expanded cohort including data on 1,136 patients with a median follow-up of 26.6 years. The median patient age at diagnosis was 11 years (range, birth to 16 years), and the patients were followed for 23,212 person-years after HL diagnosis.

In all, 162 patients developed 196 SMNs, including breast cancer (n=54), basal cell carcinoma (n=34), thyroid cancer (n=30), colorectal cancer (n=15), lung cancer (n=11), and other malignancies (n=40). The disease site was not available in 12 cases.

The cumulative incidence of any SMN 40 years after HL diagnosis was 26.4%. By age 50, the cumulative incidence of any SMN was 27.2%.

The standardized incidence ratio for the entire cohort was 14.0, compared with the general population as derived from the Surveillance, Epidemiology and End Results database.

Risk factors by cancer type

Females treated with chest radiotherapy between the ages of 10 and 16 who did not receive alkylating agents or received low doses of alkylating agents had the highest risk of developing breast cancer. The cumulative incidence of breast cancer by age 50 was 45.3% in these patients.

The patients with the highest risk for subsequent lung cancer were males treated with chest radiotherapy before age 10. The cumulative incidence of lung cancer by age 50 was 4.2% in these patients.

Patients with the highest risk for colorectal cancer had received abdominal/pelvic radiotherapy and high-dose alkylating agents. The cumulative incidence of colorectal cancer by age 50 was 9.5% in these patients.

Patients with the highest risk for thyroid cancers were females who had been treated with radiotherapy to the neck before the age of 10. The cumulative incidence of thyroid cancer by age 50 was 17.3% in these patients.

The investigators noted that HL patients treated more recently are likely to have received lower doses and volumes of radiotherapy compared to patients treated in the 1950s, ’60s and ’70s.

“However, for the cohort of patients treated between 1955 and 1986, it is clear that continued surveillance for SMNs is essential because their risk continues to increase as these survivors enter their fourth and subsequent decades of life,” the investigators wrote.

They did not report a funding source for this research or make any conflict-of-interest disclosures.

And although the risk of SMNs appears to be somewhat lower for patients treated in more recent decades, it is still significantly elevated, compared with that of the general population, according to Anna S. Holmqvist, MD, PhD, from Lund University (Sweden), and her colleagues.

“A major goal of the current study was to develop evidence with which to guide the screening of survivors of HL for the development of [solid] SMNs,” the investigators wrote in Cancer.

They examined at data from the Late Effects Study Group, a multinational cohort of patients aged 16 years or younger who were treated for Hodgkin lymphoma and other cancers from 1955 to 1986.

The current report is the third update from an expanded cohort, including data on 1,136 patients with a median follow-up of 26.6 years. The median patient age at diagnosis was 11 years and the patients were followed for 23,212 person-years following the Hodgkin lymphoma diagnosis.

In all, 162 patients developed a total of 196 solid SMNs, including breast cancer in 54 patients, basal cell carcinoma in 34 patients, thyroid cancer in 30, colorectal cancer in 15, lung cancer in 11, other malignancies in 40, and disease site not available in 12 patients.

The cumulative incidence of any solid SMN 40 years after a diagnosis of Hodgkin lymphoma was 26.4%. The standardized incidence ratio for the entire cohort was 14.0, compared with the general population as derived from the Surveillance, Epidemiology and End Results database.

Predisposing factors for breast cancer in females included a Hodgkin lymphoma diagnosis from the ages of 10-16 years, and treatment with radiotherapy to the chest.

The patients at highest risk for subsequent development of lung cancer were males treated with chest radiotherapy before age 10 years. Those at highest risk for colorectal cancer were males and females who had received abdominal/pelvic radiotherapy and high-dose alkylating agents. Patients at highest risk for thyroid cancers were females who had been treated with radiotherapy to the neck before the age of 10.

The cumulative incidence for breast cancer by age 50 years for those at highest risk was 45.3%. The respective cumulative incidences for lung, colorectal, and thyroid cancers by age 50 were 4.2%, 9.5%, and 17.3%.

The investigators noted that patients treated more recently are likely to have received lower doses and volumes of radiotherapy, compared with patients treated in 1970s and earlier. “However, for the cohort of patients treated between 1955 and 1986, it is clear that continued surveillance for [solid] SMNs is essential because their risk continues to increase as these survivors enter their fourth and subsequent decades of life.”

No specific funding source for the study was reported. The authors made no financial disclosures.

In all, 162 patients developed a total of 196 solid SMNs, including breast cancer in 54 patients, basal cell carcinoma in 34 patients, thyroid cancer in 30, colorectal cancer in 15, lung cancer in 11, other malignancies in 40, and disease site not available in 12 patients.

The cumulative incidence of any solid SMN 40 years after a diagnosis of Hodgkin lymphoma was 26.4%. The standardized incidence ratio for the entire cohort was 14.0, compared with the general population as derived from the Surveillance, Epidemiology and End Results database.

Predisposing factors for breast cancer in females included a Hodgkin lymphoma diagnosis from the ages of 10-16 years, and treatment with radiotherapy to the chest.

The patients at highest risk for subsequent development of lung cancer were males treated with chest radiotherapy before age 10 years. Those at highest risk for colorectal cancer were males and females who had received abdominal/pelvic radiotherapy and high-dose alkylating agents. Patients at highest risk for thyroid cancers were females who had been treated with radiotherapy to the neck before the age of 10.

The cumulative incidence for breast cancer by age 50 years for those at highest risk was 45.3%. The respective cumulative incidences for lung, colorectal, and thyroid cancers by age 50 were 4.2%, 9.5%, and 17.3%.

The investigators noted that patients treated more recently are likely to have received lower doses and volumes of radiotherapy, compared with patients treated in 1970s and earlier. “However, for the cohort of patients treated between 1955 and 1986, it is clear that continued surveillance for [solid] SMNs is essential because their risk continues to increase as these survivors enter their fourth and subsequent decades of life.”

No specific funding source for the study was reported. The authors made no financial disclosures.

Survivors of childhood Hodgkin lymphoma have a 14-fold greater risk for second cancers, compared with the general population, according to newly published data.

The subsequent malignant neoplasms (SMNs) tend to follow specific patterns depending on the patient’s age at treatment, sex, treatment modality, and body region treated.

And although the risk of SMNs appears to be somewhat lower for patients treated in more recent decades, it is still significantly elevated, compared with that of the general population, according to Anna S. Holmqvist, MD, PhD, from Lund University (Sweden), and her colleagues.

“A major goal of the current study was to develop evidence with which to guide the screening of survivors of HL for the development of [solid] SMNs,” the investigators wrote in Cancer.

They examined at data from the Late Effects Study Group, a multinational cohort of patients aged 16 years or younger who were treated for Hodgkin lymphoma and other cancers from 1955 to 1986.

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended expanding the marketing authorization for brentuximab vedotin (BV).

The CHMP has recommended approval for BV (Adcetris) in combination with doxorubicin, vinblastine, and dacarbazine (AVD) to treat adults with previously untreated, CD30+, stage IV Hodgkin lymphoma (HL).

The CHMP’s recommendation will be reviewed by the European Commission (EC), which has the authority to approve medicines for use in the European Union, Norway, Iceland, and Liechtenstein.

The EC usually makes a decision within 67 days of a CHMP recommendation.

BV is already EC-approved to treat adults with:

• CD30+ HL at increased risk of relapse or progression following autologous stem cell transplant (ASCT)
• Relapsed or refractory, CD30+ HL following ASCT or following at least two prior therapies when ASCT or multi-agent chemotherapy is not a treatment option
• Relapsed or refractory systemic anaplastic large-cell lymphoma
• CD30+ cutaneous T-cell lymphoma after at least one prior systemic therapy.

Phase 3 trial

The CHMP’s recommendation to approve BV in combination with AVD is supported by the phase 3 ECHELON-1 trial (NCT01712490).

Result from ECHELON-1 were presented at the 2017 ASH Annual Meeting and simultaneously published in The New England Journal of Medicine.

In this trial, researchers compared BV plus AVD (BV+AVD) to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) as frontline treatment for 1334 patients with advanced HL.

The primary endpoint was modified progression-free survival (PFS), which was defined as time to progression, death, or evidence of non-complete response after completion of frontline therapy followed by subsequent anticancer therapy.

According to an independent review committee, BV+AVD provided a significant improvement in modified PFS compared to ABVD. The hazard ratio was 0.77 (P=0.035), which corresponds to a 23% reduction in the risk of progression, death, or the need for additional anticancer therapy.

The 2-year modified PFS rate was 82.1% in the BV+AVD arm and 77.2% in the ABVD arm.

There was no significant difference between the treatment arms when it came to response rates or overall survival.

The objective response rate was 86% in the BV+AVD arm and 83% in the ABVD arm (P=0.12). The complete response rate was 73% and 70%, respectively (P=0.22).

The interim 2-year overall survival rate was 97% in the BV+AVD arm and 95% in the ABVD arm (hazard ratio=0.72; P=0.19).

The overall incidence of adverse events (AEs) was 99% in the BV+AVD arm and 98% in the ABVD arm. The incidence of grade 3 or higher AEs was 83% and 66%, respectively, and the incidence of serious AEs was 43% and 27%, respectively.

Neutropenia, febrile neutropenia, and peripheral neuropathy were more common with BV+AVD, while pulmonary toxicity was more common with ABVD.

The ECHELON-1 trial was sponsored by Millennium Pharmaceuticals, Inc. (a Takeda company) in collaboration with Seattle Genetics, Inc.

SAN DIEGO—A phase 1 study suggests lymphodepletion can improve the efficacy of CD30-directed chimeric antigen receptor (CAR) T-cell therapy in patients with Hodgkin lymphoma (HL).

Researchers observed improved responses in HL patients treated with fludarabine and cyclophosphamide prior to CD30.CAR T-cell therapy.

This lymphodepleting regimen was also associated with increased toxicity, compared to no lymphodepletion. However, researchers consider the regimen safe.

Carlos A. Ramos, MD, of Baylor College of Medicine in Houston, Texas, presented these results at the 2018 ASH Annual Meeting (abstract 680*).

Without lymphodepletion

Dr. Ramos first discussed a previous phase 1 trial (NCT01316146), which was published in The Journal of Clinical Investigation in 2017.

In this trial, he and his colleagues had tested CD30.CAR T-cell therapy in patients with relapsed/refractory, CD30+ HL or T-cell non-Hodgkin lymphoma. None of these patients underwent lymphodepletion.

There were no dose-limiting toxicities in this trial—including no neurotoxicity or cytokine release syndrome—but responses were “limited,” according to Dr. Ramos.

Three patients achieved a complete response (CR), three had stable disease, and three progressed.

“Although we saw no significant toxicities and some good clinical responses . . ., the bottom line is that the responses were still quite limited, with several patients having, at most, stable disease or progressive disease,” Dr. Ramos said.

With lymphodepletion

Results from the previous trial prompted Dr. Ramos and his colleagues to conduct the RELY-30 trial (NCT02917083) and investigate whether lymphodepletion would improve responses to CD30.CAR T-cell therapy.

Thus far, 11 patients have been treated on this trial. All had relapsed, CD30+ HL at baseline. Six patients are male, and their median age at baseline was 30 (range, 17-69).

The patients had a median of 5 prior treatments (range, 2-9). This included PD-1 inhibitors (n=10), brentuximab vedotin (n=8), and transplant (n=6).

All patients received lymphodepletion with cyclophosphamide at 500 mg/m² and fludarabine at 30 mg/m² daily for 3 days. They then received CD30.CAR T-cell therapy at 2×10⁷ cells/m² or 1×10⁸ cells/m².

Dr. Ramos noted that CD30.CAR T-cell expansion was dose-dependent and increased by lymphodepleting chemotherapy.

“The peak expansion is much higher [with lymphodepletion], probably in the order of two to three logs higher than what we see without lymphodepleting chemotherapy,” he said. “So chemotherapy makes a difference.”

Increased CD30.CAR T-cell expansion was associated with improved response. Of the nine evaluable patients, six achieved a CR, and three progressed.

Four complete responders were still in CR at last follow-up, one of them for more than a year. However, two complete responders ultimately progressed.

In addition to improved responses, the researchers observed increased toxicity in this trial. Dr. Ramos said some of these toxicities are “probably attributable” to the lymphodepleting chemotherapy.

Toxicities included grade 1 cytokine release syndrome (no tocilizumab required), maculopapular rash, transient cytopenias, nausea, vomiting, and alopecia.

Dr. Ramos said these results suggest adoptive transfer of CD30.CAR T cells is “safe, even with chemotherapy.”

He noted that the duration of response with this treatment is unknown, but trial enrollment and follow-up are ongoing.

RELY-30 was sponsored by Baylor College of Medicine. Dr. Ramos reported relationships with Novartis, Celgene, Bluebird Bio, and Tessa Therapeutics.

SAN DIEGO—Fludarabine is “very important” for lymphodepletion prior to CD30-directed chimeric antigen receptor (CAR) T-cell therapy, according to a presentation at the 2018 ASH Annual Meeting.

A phase 1/2 study showed that bendamustine alone was not sufficient as lymphodepletion.

However, adding fludarabine to bendamustine could enhance responses to CD30.CAR T-cell therapy and improve progression-free survival (PFS) in patients with Hodgkin or non-Hodgkin lymphoma.

Natalie S. Grover, MD, of the University of North Carolina in Chapel Hill, presented these results as abstract 681.*

This trial (NCT02690545) included patients with relapsed/refractory, CD30+ Hodgkin lymphoma or T-cell non-Hodgkin lymphoma.

Twenty-four adult patients have been treated thus far. Twenty-two had classical Hodgkin lymphoma, one had Sézary syndrome, and one had enteropathy-associated T-cell lymphoma.

The patients’ median age at baseline was 34.5 years (range, 23-69), and they had received a median of 7.5 prior lines of therapy (range, 3-17).

Prior treatments included brentuximab vedotin (n=23), checkpoint inhibitors (n=16), autologous transplant (n=17), and allogeneic transplant (n=7).

In this trial, patients could receive bridging therapy while their T cells were being processed. They then underwent lymphodepletion and received CAR T-cell therapy at one of two doses.

Bendamustine alone

Eight patients received lymphodepletion with 2 days of bendamustine at 90 mg/m². Three of these patients received CD30.CAR T-cell therapy at 1×10⁸ cells/m², and all three progressed.

Of the five patients who received CAR T-cell therapy at a dose of 2×10⁸ cells/m², one progressed, one had stable disease, and three had a complete response (CR).

However, all three complete responders were in CR prior to lymphodepletion as a result of bridging therapy.

“Responses were more modest than what we were hoping for with lymphodepletion,” Dr. Grover noted. “We looked at the cytokine levels in patients getting bendamustine lymphodepletion and saw that bendamustine wasn’t supporting an ideal cytokine milieu. IL-7 and IL-15 are important for T-cell expansion, and these levels were not increased in patients post-bendamustine.”

When the researchers added fludarabine to the lymphodepleting regimen, they observed an increase in T-cell expansion.

Bendamustine plus fludarabine

Sixteen patients received bendamustine plus fludarabine prior to CAR T-cell therapy. The regimen consisted of 3 days of bendamustine at 70 mg/m² and fludarabine at 30 mg/m².

All 16 patients received CAR T cells at 2×10⁸ cells/m², which was the recommended phase 2 dose.

“Responses were more impressive in the bendamustine-fludarabine cohort,” Dr. Grover noted.

Twelve of the 16 patients achieved a CR, although two patients were already in CR prior to lymphodepletion.

Two patients had a partial response, one had stable disease, and one progressed.

PFS and toxicity

Dr. Grover and her colleagues also assessed PFS. At a median follow-up of 100 days, the median PFS was 164 days for the entire cohort, excluding patients who were in CR prior to lymphodepletion.

The median PFS was 396 days for the bendamustine-fludarabine cohort and 55 days for patients in the bendamustine-alone cohort (P=0.001).

There was no neurotoxicity in this trial.

Three patients developed cytokine release syndrome (CRS). Two patients had grade 1 CRS that resolved spontaneously, and one patient had grade 2 CRS, which responded to tocilizumab. Two of the patients with CRS had T-cell lymphoma. The Sézary patient had grade 2 CRS.

Eight patients had a mild rash, one of whom had a rash at baseline.

“CAR T cells against CD30 preceded by lymphodepletion with bendamustine and fludarabine have promising efficacy and a good safety profile in treating patients with relapsed/refractory, CD30+ lymphomas,” Dr. Grover said in closing.

“Fludarabine is very important in enhancing cytokines for improved growth and persistence of CAR T cells.”

This trial was sponsored by UNC Lineberger Comprehensive Cancer Center. Dr. Grover reported consulting for Seattle Genetics.

“Responses were more modest than what we were hoping for with lymphodepletion,” Dr. Grover noted. “We looked at the cytokine levels in patients getting bendamustine lymphodepletion and saw that bendamustine wasn’t supporting an ideal cytokine milieu. IL-7 and IL-15 are important for T-cell expansion, and these levels were not increased in patients post-bendamustine.”

When the researchers added fludarabine to the lymphodepleting regimen, they observed an increase in T-cell expansion.

Bendamustine plus fludarabine

Sixteen patients received bendamustine plus fludarabine prior to CAR T-cell therapy. The regimen consisted of 3 days of bendamustine at 70 mg/m² and fludarabine at 30 mg/m².

All 16 patients received CAR T cells at 2×10⁸ cells/m², which was the recommended phase 2 dose.

“Responses were more impressive in the bendamustine-fludarabine cohort,” Dr. Grover noted.

Twelve of the 16 patients achieved a CR, although two patients were already in CR prior to lymphodepletion.

Two patients had a partial response, one had stable disease, and one progressed.

PFS and toxicity

Dr. Grover and her colleagues also assessed PFS. At a median follow-up of 100 days, the median PFS was 164 days for the entire cohort, excluding patients who were in CR prior to lymphodepletion.

The median PFS was 396 days for the bendamustine-fludarabine cohort and 55 days for patients in the bendamustine-alone cohort (P=0.001).

There was no neurotoxicity in this trial.

Three patients developed cytokine release syndrome (CRS). Two patients had grade 1 CRS that resolved spontaneously, and one patient had grade 2 CRS, which responded to tocilizumab. Two of the patients with CRS had T-cell lymphoma. The Sézary patient had grade 2 CRS.

Eight patients had a mild rash, one of whom had a rash at baseline.

“CAR T cells against CD30 preceded by lymphodepletion with bendamustine and fludarabine have promising efficacy and a good safety profile in treating patients with relapsed/refractory, CD30+ lymphomas,” Dr. Grover said in closing.

“Fludarabine is very important in enhancing cytokines for improved growth and persistence of CAR T cells.”

This trial was sponsored by UNC Lineberger Comprehensive Cancer Center. Dr. Grover reported consulting for Seattle Genetics.

SAN DIEGO—Fludarabine is “very important” for lymphodepletion prior to CD30-directed chimeric antigen receptor (CAR) T-cell therapy, according to a presentation at the 2018 ASH Annual Meeting.

A phase 1/2 study showed that bendamustine alone was not sufficient as lymphodepletion.

However, adding fludarabine to bendamustine could enhance responses to CD30.CAR T-cell therapy and improve progression-free survival (PFS) in patients with Hodgkin or non-Hodgkin lymphoma.

Natalie S. Grover, MD, of the University of North Carolina in Chapel Hill, presented these results as abstract 681.*

This trial (NCT02690545) included patients with relapsed/refractory, CD30+ Hodgkin lymphoma or T-cell non-Hodgkin lymphoma.

Twenty-four adult patients have been treated thus far. Twenty-two had classical Hodgkin lymphoma, one had Sézary syndrome, and one had enteropathy-associated T-cell lymphoma.

The patients’ median age at baseline was 34.5 years (range, 23-69), and they had received a median of 7.5 prior lines of therapy (range, 3-17).

Prior treatments included brentuximab vedotin (n=23), checkpoint inhibitors (n=16), autologous transplant (n=17), and allogeneic transplant (n=7).

In this trial, patients could receive bridging therapy while their T cells were being processed. They then underwent lymphodepletion and received CAR T-cell therapy at one of two doses.

Bendamustine alone

Eight patients received lymphodepletion with 2 days of bendamustine at 90 mg/m². Three of these patients received CD30.CAR T-cell therapy at 1×10⁸ cells/m², and all three progressed.

Of the five patients who received CAR T-cell therapy at a dose of 2×10⁸ cells/m², one progressed, one had stable disease, and three had a complete response (CR).

However, all three complete responders were in CR prior to lymphodepletion as a result of bridging therapy.

“Responses were more modest than what we were hoping for with lymphodepletion,” Dr. Grover noted. “We looked at the cytokine levels in patients getting bendamustine lymphodepletion and saw that bendamustine wasn’t supporting an ideal cytokine milieu.

Audience at Leukemia and Lymphoma: Europe and the USA, Linking Knowledge and Practice

DUBROVNIK, CROATIA—An updated scoring system can more accurately identify lymphoma patients who may require thromboprophylaxis, according to researchers.

The revised scoring system, ThroLy, proved more effective than other systems for predicting thromboembolic events in lymphoma patients.

Researchers found the updated ThroLy had a positive predictive value of 22% to 25%, a negative predictive value of 96%, sensitivity of 56% to 57%, and specificity of 85% to 87%.

Darko Antić, MD, PhD, of the University of Belgrade in Serbia, presented these findings at Leukemia and Lymphoma: Europe and the USA, Linking Knowledge and Practice.

Dr. Antić said he and his colleagues developed ThroLy because other systems used to predict venous thromboembolism (VTE) are not quite right for lymphoma. He noted that the Padua score is not designed for cancer patients, and the Khorana score is predominantly for solid tumor malignancies.

“It’s good . . . , but it’s not specific for lymphoma patients,” Dr. Antić said.

With this in mind, he and his colleagues developed ThroLy. They based the scoring system on variables used in the Padua and Khorana systems as well as variables that are specific to lymphoma patients.

In a past study*, the researchers found several variables that were independently associated with risk for VTE in lymphoma:

• Previous VTE
• Previous acute myocardial infarction/stroke
• Mediastinal involvement
• Body mass index > 30 kg/m²
• Reduced mobility
• Extranodal localization
• Development of neutropenia
• Hemoglobin level < 100g/L.

Previous VTE, previous acute myocardial infarction/stroke, obesity, and mediastinal involvement were all worth 2 points, and the other factors were worth a single point.

Patients with scores of 0 to 1 were considered low-risk, patients with scores of 2 to 3 were considered intermediate-risk, and patients with scores of 4 or greater were considered high-risk.

Prospective validation

To validate and refine ThroLy, Dr. Antić and his colleagues used it to assess 1723 lymphoma patients treated at 8 institutions in Austria, Croatia, France, Jordan, Macedonia, Spain, Switzerland, and the United States.

Patients had indolent non-Hodgkin lymphoma (n=467), aggressive non-Hodgkin lymphoma (n=647), chronic lymphocytic leukemia/small lymphocytic lymphoma (n=235), and Hodgkin lymphoma (n=366). Most subjects (84%) were outpatients.

Nine percent of patients had thrombosis (n=142), with 7% having VTE (n=121).

ThroLy had a positive predictive value of 17%, compared to 11% with Khorana and 13% with Padua. The negative predictive value was 93%, 92%, and 95%, respectively.

The sensitivity was 51% with ThroLy, 42% with Khorana, and 70% with Padua. The specificity was 72%, 64%, and 52%, respectively.

“The positive predictive value was low [with ThroLy] but definitely higher than the positive predictive value of the other two [scoring systems],” Dr. Antić noted.

Updated models

To further improve ThroLy, the researchers updated the system, creating two new models.

Model 1 included the following variables:

• Type of lymphoma/clinical stage (aggressive/advanced)—1 point
• Previous VTE—5 points
• Reduced mobility—2 points
• Hemoglobin level < 100 g/L—1 point
• Presence of vascular devices—1 point.

Model 2 included all of the aforementioned variables as well as thrombophilic condition, which was worth 1 point.

With these models, patients were divided into two risk groups—low-risk (≤ 2 points) and high-risk (>2 points).

For Model 1, the positive predictive value was 22%, the negative predictive value was 96%, the sensitivity was 56%, and the specificity was 85%.

For Model 2, the positive predictive value was 25%, the negative predictive value was 96%, the sensitivity was 57%, and the specificity was 87%.

Dr. Antić said there were no major differences in model discrimination and calibration according to the country in which a patient was treated or whether patients were treated in inpatient or outpatient settings.

Dr. Antić did not report any conflicts of interest.

New York—Although the data set is small and not yet mature, chimeric antigen receptor (CAR) T-cell therapy appears to be a promising approach for Hodgkin lymphoma, according to Philippe Armand, MD, PhD, of Dana-Farber/Brigham and Women’s Cancer Center and the Massachusetts General Hospital Cancer Center.

While based on a handful of patients, the data do suggest this approach may play a role either by targeting CD30 or Epstein Barr virus (EBV), Dr. Armand said in a presentation at the NCCN 13^th Annual Congress: Hematologic Malignancies.

“Most importantly perhaps, like it's experience outside of Hodgkin lymphoma, it may really have curative potential, based on the long CR rates that have been already exhibited,” he told attendees at the NCCN conference.

Much of the published clinical experience to date is with CD30-directed CAR Ts, Dr. Armand said, noting that in Hodgkin lymphoma, results so far show promise for this particular approach.

In a recent phase 1 dose escalation study, 9 patients with relapsed/refractory Hodgkin lymphoma or anaplastic large-cell lymphoma (ALCL) received infusions of autologous T cells modified to express CD30-specific CAR T cells encoding the CD28 costimulatory domain, with no conditioning regimen.

Out of 7 relapsed Hodgkin patients, one had a complete response (CR) lasting beyond 2.5 years following a second infusion. Another had a CR persisting almost 2 years and 3 had transient stable disease.

One of the 2 ALCL patients had a CR lasting 9 months after a fourth infusion. No toxicities attributable to the therapy were seen, according to investigators.

The CD30 CAR T cells are being evaluated with a conditioning regimen in the phase 1 RELY-30 trial. According to Dr. Armand, preliminary results presented at the EBMT 2018 meeting showed better expansion of CAR T cells and responses in 3 out of 5 patients, including 2 CRs.

A CD30-directed CAR T-cell therapy with a 4-1bb costimulatory domain has also been tested in a small group of Hodgkin patients with a response rate of 35%, including some CRs. Response rates were lower in patients with extranodal involvement, although that needs to be validated with further study, according to Dr. Armand.

A considerable amount of active research is ongoing in China, Dr. Armand said, while a phase 1 study of T cells expressing a fully human anti-CD30 CAR is being evaluated in the United States in CD30-expressing lymphomas, he added.

Among non-CD30-targeted products, a CD19 CAR-T approach has been tried in Hodgkin lymphoma, though preliminary results suggest only transient activity.

An interesting approach has been the targeting of EBV, Dr. Armand noted. Recently reported results showed that two doses of T cells with specificity for EBV-derived tumor antigens induced clinical responses in patients with EBV-positive Hodgkin lymphoma.

The cells were engineered to express dominant-negative TGF-β receptor type 2 (DNRII).

“We know that TGF-β provides a strong immunosuppressant signal in the tumor microenvironment,” Dr. Armand said, noting that some of the responses in the 7 evaluable patients lasted 4 years or more.

Two immunologists have been awarded the Nobel Prize in Physiology or Medicine for discoveries that represent a “paradigmatic shift in the fight against cancer,” the Nobel committee said.

James P. Allison, PhD, of MD Anderson Cancer Center, and Tasuku Honjo, MD, PhD, of Kyoto University, shared the prize for their discovery of cancer therapies that work by inhibiting negative immune regulation.

Dr. Allison studied the protein CTLA-4 found on T cells, which acts as a T-cell brake, and Dr. Honjo discovered a protein on immune cells called PD-1 that also acts as a T-cell brake.

In addition to sharing the honor, the scientists will split the 9 million Swedish kronor ($1.01 million) that comes with the prize.

Drs. Allison and Honjo, working in parallel, pursued different strategies for inhibiting the brakes on the immune system. Both strategies produced effective checkpoint inhibitors in the treatment of cancer.

James P. Allison

Dr. Allison was one of several scientists during the 1990s who noticed that CTLA-4 functions as a brake on T cells. Unlike other scientists, however, he set out to investigate whether blocking CTLA-4 with an antibody he had already developed could release the brake on the immune system.

The antibody had “spectacular” effects in curing mice with cancer. Despite little interest from the pharmaceutical industry, Dr. Allison continued efforts to develop the antibody therapy for humans.

The antibody turned out to be ipilimumab, which was approved in 2011 by the U.S. Food and Drug Administration (FDA) for the treatment of advanced melanoma.

Tasuko Honjo

A few years prior to Dr. Allison’s finding, Dr. Honjo discovered PD-1 and set out to determine its function. PD-1 also operates as a T-cell brake, but it uses a different mechanism than does CTLA-4.

Dr. Honjo and others demonstrated in animal experiments that PD-1 blockade could be an effective anticancer therapy. Over the years he demonstrated the efficacy of targeting PD-1 in different types of human cancers.

The first two PD-1 checkpoint inhibitors—pembrolizumab and nivolumab—were approved by the FDA in 2014 for the treatment of melanoma.

Nivolumab is also approved to treat classical Hodgkin lymphoma (HL), non-small cell lung cancer (NSCLC), small cell lung cancer, squamous cell carcinoma of the head and neck, colorectal cancer, hepatocellular carcinoma, renal cell carcinoma, urothelial carcinoma, and microsatellite instability-high or mismatch repair deficient colorectal cancer.

Pembrolizumab is also approved to treat primary mediastinal large B-cell lymphoma, advanced NSCLC, classical HL, advanced gastric cancer, advanced cervical cancer, head and neck squamous cell cancer, advanced urothelial bladder cancer, and microsatellite instability-high cancer.

And targeting both CTLA-4 and PD-1 in combination therapy together may prove to be even more effective in eliminating cancer cells than either strategy alone, as is being demonstrated in patients with melanoma.

The Nobel organization wrote in a press release, “Checkpoint therapy has now revolutionized cancer treatment and has fundamentally changed the way we view how cancer can be managed.”

In addition to sharing the honor, the scientists will split the 9 million Swedish kronor ($1.01 million) that comes with the prize.

Drs. Allison and Honjo, working in parallel, pursued different strategies for inhibiting the brakes on the immune system. Both strategies produced effective checkpoint inhibitors in the treatment of cancer.

James P. Allison

Dr. Allison was one of several scientists during the 1990s who noticed that CTLA-4 functions as a brake on T cells. Unlike other scientists, however, he set out to investigate whether blocking CTLA-4 with an antibody he had already developed could release the brake on the immune system.

The antibody had “spectacular” effects in curing mice with cancer. Despite little interest from the pharmaceutical industry, Dr. Allison continued efforts to develop the antibody therapy for humans.

The antibody turned out to be ipilimumab, which was approved in 2011 by the U.S. Food and Drug Administration (FDA) for the treatment of advanced melanoma.

Tasuko Honjo

A few years prior to Dr. Allison’s finding, Dr. Honjo discovered PD-1 and set out to determine its function. PD-1 also operates as a T-cell brake, but it uses a different mechanism than does CTLA-4.

Dr. Honjo and others demonstrated in animal experiments that PD-1 blockade could be an effective anticancer therapy. Over the years he demonstrated the efficacy of targeting PD-1 in different types of human cancers.

The first two PD-1 checkpoint inhibitors—pembrolizumab and nivolumab—were approved by the FDA in 2014 for the treatment of melanoma.

Nivolumab is also approved to treat classical Hodgkin lymphoma (HL), non-small cell lung cancer (NSCLC), small cell lung cancer, squamous cell carcinoma of the head and neck, colorectal cancer, hepatocellular carcinoma, renal cell carcinoma, urothelial carcinoma, and microsatellite instability-high or mismatch repair deficient colorectal cancer.

Pembrolizumab is also approved to treat primary mediastinal large B-cell lymphoma, advanced NSCLC, classical HL, advanced gastric cancer, advanced cervical cancer, head and neck squamous cell cancer, advanced urothelial bladder cancer, and microsatellite instability-high cancer.

And targeting both CTLA-4 and PD-1 in combination therapy together may prove to be even more effective in eliminating cancer cells than either strategy alone, as is being demonstrated in patients with melanoma.

The Nobel organization wrote in a press release, “Checkpoint therapy has now revolutionized cancer treatment and has fundamentally changed the way we view how cancer can be managed.”

Two immunologists have been awarded the Nobel Prize in Physiology or Medicine for discoveries that represent a “paradigmatic shift in the fight against cancer,” the Nobel committee said.
