Hematology

Instead of flying out to San Diego in California and soaking up a bit of sunshine in between listening to new research presentations, hematologists from around the world will be glued to their computer screens next weekend, tuning into the 62nd American Society of Hematology annual meeting.  

Like many other conferences this year, the ASH meeting will be virtual because of the continuing COVID-19 pandemic, although the dates remain the same: Dec. 5-8.  

This is the premier hematology event of the year, and the largest hematology conference in the world, with around 3,500 abstracts presented this year, commented Aaron T. Gerds, MD, chair of ASH’s Committee on Communications.
 

Ruxolitinib in chronic GvHD

“One of the things that people come to ASH for is to hear about practice-changing clinical trials, and this year is no exception,” said ASH secretary Robert Brodsky, MD.

In a preview webinar, he highlighted four abstracts that offer opportunities to change practice and revamp the current standards of care.

One clinical trial that is “almost certainly a practice changer,” he said, is the REACH 3 study (abstract 77) of the JAK inhibitor ruxolitinib (Jakafi, Incyte) in patients with chronic graft-versus-host disease (GvHD) after a stem cell transplant.

“This has been really hard to treat in patients undergoing allogeneic bone marrow transplants,” said Brodsky. “Steroids are the first-line treatment, but after that, nothing else has shown any improvement, and even steroids don’t work that well.”

There is currently no approved second-line therapy for chronic forms of GvHD, he emphasized. The main endpoint of the trial was overall response rate, which was doubled with ruxolitinib compared to the best available therapy (50% vs 25%).

“This is the first successful phase 3 trial for chronic GvHD,” Brodsky commented.  
 

Transplants for older patients with MDS

Transplant offers the only curative option for myelodysplastic syndromes (MDS), but typically this option is offered to younger patients because benefits for older adults have not been well-defined, Brodsky noted.

New data from a clinical trial conducted in patients with advanced MDS aged 50-75 years (abstract 75) offers the most definitive evidence to date that allogeneic hematopoietic cell transplantation (AHCT) can significantly improve outcomes for older adults.  

It’s clear that transplant is the standard of care in younger patients, Brodsky commented, and although there is a trend of offering it to older patients, some are not getting referred and instead are being offered palliative care. “The thinking is that bone marrow transplant would be too toxic in this age group,” he said. “But what is very clear here is that, in an intent-to-treat analysis, there was a significant survival advantage – 48% versus 27% at 3 years for transplantation – and it was seen across all subgroups.”
 

Subcutaneous daratumumab

New data on a subcutaneous formulation of daratumumab (Darzalex, Janssen), which is usually given by intravenous infusion, will be presented from the APOLLO trial (abstract 412) in patients with relapsed/refractory multiple myeloma.

Patients who received subcutaneous daratumumab combined with pomalidomide and dexamethasone had a 37% reduction in disease progression or death compared to those who received pomalidomide and dexamethasone alone.

“From previous years we’ve learned that daratumumab has had a major impact on outcomes in multiple myeloma,” said Brodsky. “The nice thing about the subcutaneous formulation is that it can be administered quickly and in an outpatient setting, which is especially important in the COVID era.”  
 

Negative data with tranexamic acid

The fourth abstract highlighted by Brodsky is a negative study, but its findings can help guide clinical practice, he said. The a-TREAT study (abstract 2) showed that, despite being routinely used in the clinical setting, tranexamic acid does not prevent bleeding when administered prophylactically to severely thrombocytopenic patients undergoing treatment for hematologic malignancies.

“They found absolutely no difference in bleeding or need for transfusion,” said Brodsky. “What they did find was more catheter-associated blood clots in the tranexamic acid group. This is a practice changer in that it probably should not be given prophylactically to patients with thrombocytopenia.”
 

‘Very exciting’ news about gene therapy

Brodsky also highlighted several late-breaking abstract that will be presented at the meeting.

In particular, the first data on a gene therapy for hemophilia B (abstract LBA-6) are “very, very exciting,” he said. The HOPE-B trial showed a 96% response rate among patients with hemophilia B who were treated with etranacogene dezaparvovec, an investigational gene therapy composed of an adeno-associated virus serotype 5 (AAV5) vector containing a codon-optimized Padua variant human factor IX.

Brodsky pointed out that this was a large trial with 54 patients, but importantly, it included patients with pre-existing anti-AAV5 neutralizing antibodies. “About 40% of patients have naturally occurring antibodies to AAV5, and they have been excluded from previous trials because it was thought they wouldn’t take the vector,” said Brodsky. “But only one patient didn’t get a response.”

Following a single dose of etranacogene dezaparvovec, Factor IX activity increased into the mild to normal range without the need for prophylactic immunosuppression. Treated patients were able to discontinue prophylaxis and bleeding was controlled in most of the cohort.

“This is a big advance and we are getting very close to the point where gene therapy is going to be standard of care for some forms of hemophilia,” said Brodsky. However, he added that “we will still need to see more patients and have longer follow-up.”

He added that, with time, the technology behind gene therapy will probably become less expensive and more accessible to more patients, which will help become a standard of care.

This is also the hope for the technology behind chimeric antigen receptor T-cell (CAR-T) therapy, he added. At present, this cellular therapy is manufactured individually for each patient and is very expensive, but work on “off-the-shelf” products is underway. This topic will be explored during the presidential symposium, entitled, “Universal Donor Solutions in Hematology.”

New data on one of the currently available CAR-T cell products will be presented at the meeting. The phase 2 ZUMA-5 trial showed that axicabtagene ciloleucel (Axi-Cel) may be a viable option for some patients with high-risk non-Hodgkin lymphoma who have not responded to standard treatments (abstract 700).

At a median follow-up of almost 18 months, 92% of participants achieved an objective response, and 78% achieved a complete response to the treatment. By 12 months, 72% were still in response, and at 17.5 months, 64% were still in response.

“We were very impressed with the magnitude of the responses, and also the durability,” said senior study author Caron Jacobson, MD, of the Dana-Farber Cancer Institute, Boston, in a press release. “I was also struck early on by how favorable the safety profile was compared to what we’ve been seeing in the fast-growing lymphomas, such as large B cell lymphoma.”
 

Race and bloods cancers

ASH president Stephanie Lee, MD, MPH, highlighted several abstracts on disparities that will be presented at the meeting. One of these, which is to be presented during the plenary session, is an analysis of patient survival in acute myeloid leukemia (AML) (abstract 6).

It found that “self-reported race was the best indicator of survival,” noted Lee.

Overall survival at 3 years was 41% in White patients versus 32% in Black patients, a difference that was highly significant, she noted.

Part of the study also evaluated patients who were all on the same chemotherapy protocol, “so there was no effect of different treatment since they were on therapy determined by the trial,” said Lee.

Black patients were less likely to have normal cytogenetics compared with White patients (38% vs 51%; P = .01) and had a lower frequency of prognostically favorable NPM1 mutations (25% vs 38%; P = .04), but higher frequencies of spliceosome gene mutations (24% vs 12%; P = .009). Therefore, the results showed race was an independent prognosticator of poor survival in AML, aside from established molecular markers.

A special scientific session on race will be held on Dec. 5, Lee noted. While other abstracts consider race from the patient side, this session will focus on the scientist’s side, she explained, and address questions such as: “What are the implications of diversity and racism? And how does that impact scientists who are from underrepresented minorities?” 
 

COVID-19 and blood disorders

Lee also highlighted a study (abstract 215) that analyzed emerging data from the ASH Research Collaborative COVID-19 Registry for Hematology, which was developed to look at outcomes of COVID-19 infection in patients with underlying blood disorders.

An analysis of data from 250 patients at 74 sites around the world found that overall mortality was 28%. “This supports the emerging consensus that patients with hematologic malignancies experience significant morbidity and mortality from COVID-19 infection,” say the authors.

“We do need real-world data to see how SARS-CoV-2 is affecting our patients with hematologic diseases or those who don’t have a hematologic disease but who are then infected with the coronavirus and develop a hematologic problem like blood clots,” said Lee.

“More data will be coming in, but this is a good example of trying to harness real-world information to learn things until we have more controlled trials.”
 

‘Fireside chat’ with Fauci

COVID-19 will be on the agenda for a special session billed as a “fireside chat” with Anthony Fauci, MD, of the National Institute of Allergy and Infectious Diseases, National Institutes of Health.

“This will be kicking off our meeting on Saturday morning,” said Lee.

As an increasing number of health systems implement “hospital-at-home” (HaH) programs to increase their traditional hospital capacity, the Centers for Medicare & Medicaid Services has given the movement a boost by changing its regulations to allow acute care to be provided in a patient’s home under certain conditions.

The CMS announced Nov. 25 that it was launching its Acute Hospital Care at Home program “to increase the capacity of the American health care system” during the COVID-19 pandemic.

At the same time, the agency announced it was giving more flexibility to ambulatory surgery centers (ASCs) to provide hospital-level care.

The CMS said its new HaH program is an expansion of the Hospitals Without Walls initiative that was unveiled last March. Hospitals Without Walls is a set of “temporary new rules” that provide flexibility for hospitals to provide acute care outside of inpatient settings. Under those rules, hospitals are able to transfer patients to outside facilities, such as ASCs, inpatient rehabilitation hospitals, hotels, and dormitories, while still receiving Medicare hospital payments.

Under CMS’ new Acute Hospital Care at Home, which is not described as temporary, patients can be transferred from emergency departments or inpatient wards to hospital-level care at home. The CMS said the HaH program is designed for people with conditions such as the acute phases of asthma, heart failure, pneumonia, and chronic obstructive pulmonary disease. Altogether, the agency said, more than 60 acute conditions can be treated safely at home.

However, the agency didn’t say that facilities can’t admit COVID-19 patients to the hospital at home. Rami Karjian, MBA, cofounder and CEO of Medically Home, a firm that supplies health systems with technical services and software for HaH programs, said in an interview that several Medically Home clients plan to treat both COVID-19 and non-COVID-19 patients at home when they begin to participate in the CMS program in the near future.

The CMS said it consulted extensively with academic and private industry leaders in building its HaH program. Before rolling out the initiative, the agency noted, it conducted successful pilot programs in leading hospitals and health systems. The results of some of these pilots have been reported in academic journals.

Participating hospitals will be required to have specified screening protocols in place before beginning acute care at home, the CMS announced. An in-person physician evaluation will be required before starting care at home. A nurse will evaluate each patient once daily in person or remotely, and either nurses or paramedics will visit the patient in person twice a day.

In contrast, Medicare regulations require nursing staff to be available around the clock in traditional hospitals. So the CMS has to grant waivers to hospitals for HaH programs.

While not going into detail on the telemonitoring capabilities that will be required in the acute hospital care at home, the release said, “Today’s announcement builds upon the critical work by CMS to expand telehealth coverage to keep beneficiaries safe and prevent the spread of COVID-19.”
 

More flexibility for ASCs

The agency is also giving ASCs the flexibility to provide 24-hour nursing services only when one or more patients are receiving care on site. This flexibility will be available to any of the 5,700 ASCs that wish to participate, and will be immediately effective for the 85 ASCs currently participating in the Hospital Without Walls initiative, the CMS said.

The new ASC regulations, the CMS said, are aimed at allowing communities “to maintain surgical capacity and other life-saving non-COVID-19 [care], like cancer surgeries.” Patients who need such procedures will be able to receive them in ASCs without being exposed to known COVID-19 cases.

Similarly, the CMS said patients and families not diagnosed with COVID-19 may prefer to receive acute care at home if local hospitals are full of COVID-19 patients. In addition, the CMS said it anticipates patients may value the ability to be treated at home without the visitation restrictions of hospitals.
 

Early HaH participants

Six health systems with extensive experience in providing acute hospital care at home have been approved for the new HaH waivers from Medicare rules. They include Brigham and Women’s Hospital (Massachusetts); Huntsman Cancer Institute (Utah); Massachusetts General Hospital (Massachusetts); Mount Sinai Health System (New York City); Presbyterian Healthcare Services (New Mexico); and UnityPoint Health (Iowa).

The CMS said that it’s in discussions with other health care systems and expects new applications to be submitted soon.

To support these efforts, the CMS has launched an online portal to streamline the waiver request process. The agency said it will closely monitor the program to safeguard beneficiaries and will require participating hospitals to report quality and safety data on a regular basis.
 

Support from hospitals

The first health systems participating in the CMS HaH appear to be supportive of the program, with some hospital leaders submitting comments to the CMS about their view of the initiative.

“The CMS has taken an extraordinary step today, facilitating the rapid expansion of Hospitalization at Home, an innovative care model with proven results,” said Kenneth L. Davis, MD, president and CEO of the Mount Sinai Health System in New York City. “This important and timely move will enable hospitals across the country to use effective tools to safely care for patients during this pandemic.”

David Levine, MD, assistant professor of medicine and medical director of strategy and innovation for Brigham Health Home Hospital in Boston, was similarly laudatory: “Our research at Brigham Health Home has shown that we can deliver hospital-level care in our patients’ homes with lower readmission rates, more physical mobility, and a positive patient experience,” he said. “During these challenging times, a focus on the home is critical. We are so encouraged that CMS is taking this important step, which will allow hospitals across the country to increase their capacity while delivering the care all patients deserve.”
 

Scaling up quickly

If other hospitals and health systems recognize the value of HaH, how long might it take them to develop and implement these programs in the midst of a pandemic?

Atrium Health, a large health system in the Southeast, ramped up a hospital-at-home initiative last spring for its 10 hospitals in the Charlotte, N.C., area, in just 2 weeks. However, it had been working on the project for some time before the pandemic struck. Focusing mostly on COVID-19 patients, the initiative reduced the COVID-19 patient load by 20%-25% in Atrium’s hospitals.

Medically Home, the HaH infrastructure company, said in a news release that it “enables health systems to establish new hospital-at-home services in as little as 30 days.” Medically Home has partnered in this venture with Huron Consulting Group, which has about 200 HaH-trained consultants, and Cardinal Health, a large global medical supplies distributor.

Mr. Karjian said in an interview that he expects private insurers to follow CMS’ example, as they often do. “We think this decision will cause not only CMS but private insurers to cover hospital at home after the pandemic, if it becomes the standard of care, because patients have better outcomes when treated at home,” he said.

Asked for his view on why the CMS specified that patients could be admitted to an HaH only from emergency departments or inpatient settings, Mr. Karjian said that the CMS wants to make sure that patients have access to brick-and-mortar hospital care if that’s what they need. Also, he noted, this model is new to most hospitals, so the CMS wants to make sure it starts “with all the safety guardrails” in place.

Overall, Mr. Karjian said, “This is an exciting development for patients across the country. What CMS has done is terrific in terms of letting patients get the care they want, where they want it, and get the benefit of better outcomes while the nation is going through this capacity crunch for hospital beds.”

As an increasing number of health systems implement “hospital-at-home” (HaH) programs to increase their traditional hospital capacity, the Centers for Medicare & Medicaid Services has given the movement a boost by changing its regulations to allow acute care to be provided in a patient’s home under certain conditions.

The CMS announced Nov. 25 that it was launching its Acute Hospital Care at Home program “to increase the capacity of the American health care system” during the COVID-19 pandemic.

At the same time, the agency announced it was giving more flexibility to ambulatory surgery centers (ASCs) to provide hospital-level care.

The CMS said its new HaH program is an expansion of the Hospitals Without Walls initiative that was unveiled last March. Hospitals Without Walls is a set of “temporary new rules” that provide flexibility for hospitals to provide acute care outside of inpatient settings. Under those rules, hospitals are able to transfer patients to outside facilities, such as ASCs, inpatient rehabilitation hospitals, hotels, and dormitories, while still receiving Medicare hospital payments.

Under CMS’ new Acute Hospital Care at Home, which is not described as temporary, patients can be transferred from emergency departments or inpatient wards to hospital-level care at home. The CMS said the HaH program is designed for people with conditions such as the acute phases of asthma, heart failure, pneumonia, and chronic obstructive pulmonary disease. Altogether, the agency said, more than 60 acute conditions can be treated safely at home.

However, the agency didn’t say that facilities can’t admit COVID-19 patients to the hospital at home. Rami Karjian, MBA, cofounder and CEO of Medically Home, a firm that supplies health systems with technical services and software for HaH programs, said in an interview that several Medically Home clients plan to treat both COVID-19 and non-COVID-19 patients at home when they begin to participate in the CMS program in the near future.

The CMS said it consulted extensively with academic and private industry leaders in building its HaH program. Before rolling out the initiative, the agency noted, it conducted successful pilot programs in leading hospitals and health systems. The results of some of these pilots have been reported in academic journals.

Participating hospitals will be required to have specified screening protocols in place before beginning acute care at home, the CMS announced. An in-person physician evaluation will be required before starting care at home. A nurse will evaluate each patient once daily in person or remotely, and either nurses or paramedics will visit the patient in person twice a day.

In contrast, Medicare regulations require nursing staff to be available around the clock in traditional hospitals. So the CMS has to grant waivers to hospitals for HaH programs.

While not going into detail on the telemonitoring capabilities that will be required in the acute hospital care at home, the release said, “Today’s announcement builds upon the critical work by CMS to expand telehealth coverage to keep beneficiaries safe and prevent the spread of COVID-19.”
 

More flexibility for ASCs

The agency is also giving ASCs the flexibility to provide 24-hour nursing services only when one or more patients are receiving care on site. This flexibility will be available to any of the 5,700 ASCs that wish to participate, and will be immediately effective for the 85 ASCs currently participating in the Hospital Without Walls initiative, the CMS said.

The new ASC regulations, the CMS said, are aimed at allowing communities “to maintain surgical capacity and other life-saving non-COVID-19 [care], like cancer surgeries.” Patients who need such procedures will be able to receive them in ASCs without being exposed to known COVID-19 cases.

Similarly, the CMS said patients and families not diagnosed with COVID-19 may prefer to receive acute care at home if local hospitals are full of COVID-19 patients. In addition, the CMS said it anticipates patients may value the ability to be treated at home without the visitation restrictions of hospitals.
 

Early HaH participants

Six health systems with extensive experience in providing acute hospital care at home have been approved for the new HaH waivers from Medicare rules. They include Brigham and Women’s Hospital (Massachusetts); Huntsman Cancer Institute (Utah); Massachusetts General Hospital (Massachusetts); Mount Sinai Health System (New York City); Presbyterian Healthcare Services (New Mexico); and UnityPoint Health (Iowa).

The CMS said that it’s in discussions with other health care systems and expects new applications to be submitted soon.

To support these efforts, the CMS has launched an online portal to streamline the waiver request process. The agency said it will closely monitor the program to safeguard beneficiaries and will require participating hospitals to report quality and safety data on a regular basis.
 

Support from hospitals

The first health systems participating in the CMS HaH appear to be supportive of the program, with some hospital leaders submitting comments to the CMS about their view of the initiative.

Patients with hemophilia A or von Willebrand disease undergoing anterior cruciate ligament (ACL) reconstruction had rates of postoperative complications and ACL reinjuries that were not significantly different from those control patients. However, the cost of health care utilization was significantly greater for the hemophilia A and von Willebrand disease patients, according to a large retrospective database study published online in The Knee.

All patients who underwent an ACL reconstruction from 2010 to 2014 in a large commercial database were assessed. Patients with hemophilia A, hemophilia B, and von Willebrand disease were identified. Patient demographics, cost of surgery, blood product use, concomitant injuries, repeat ACL injury, complications, and various operative variables were collected.

A total of 33 patients with hemophilia A, 3 with hemophilia B patients, 63 with von Willebrand disease and 103,478 control patients who had ACL reconstruction were compared, according to Connor Zale, MD, and colleagues at Penn State Hershey (Pa.) Medical Center.
 

Similar outcomes, higher costs

Complications – including length of hospital stay, postoperative hemorrhage within 14 days after surgery, infection rates within 90 days of surgery, lysis of adhesions or manipulation under anesthesia within 90 days of surgery, concomitant injuries to the knee, additional ACL injury within 1 year of surgery, deep-vein thrombosis, and pulmonary embolism – were not statistically different between the hemophilia/von Willebrand cohorts and the control group, according to the researchers.

However, surgery and postoperative care were costlier in the hemophilia A and von Willebrand cohorts. Total health care utilization within 30 days of ACL reconstruction was significantly more expensive for patients with hemophilia A ($25,982) and those with von Willebrand disease ($16,445), compared with those among controls ($12,887). In addition, the total health care utilization costs within 90 days of ACL reconstruction were significantly higher for patients with hemophilia A ($30,310) and those with von Willebrand disease ($20,355), compared with those among controls ($14,564), with all P values less than .001.

None of the patients with hemophilia A or those with von Willebrand received blood products perioperatively, had a known major hemarthrosis, or were readmitted within 30 or 90 days, the authors noted, adding that this finding differs from previous studies. The authors speculated that, since no blood products were administered and there was no significant difference in postoperative hemorrhage, the patients with hemophilia A were preoperatively optimized for an acceptable prothrombin time and international normalized ratio and/or were more effectively managed postoperatively.

“Many surgeons may be fearful of performing an ACL reconstruction on those with hemophilia A, hemophilia B, and von Willebrand disease due to concerns over risk of a major hemarthrosis and other complications postoperatively. This study observed that hemophilia A and von Willebrand disease patients who underwent an ACL reconstruction had rates of postoperative complications that were not statistically different than those who underwent ACL reconstructions and did not have a known hypocoagulable condition,” the researchers concluded.

The authors reported that they had no potential conflicts of interest to disclose.

Factor XI has emerged as a promising target for new anticoagulants, and several strategies for inhibiting the enzyme to reduce stroke, thromboembolism, and bleeding risk are under investigation, according to Jeffrey I. Weitz, MD.

These strategies could pick up where direct-acting oral anticoagulants leave off, he suggested during a presentation at the biennial summit of the Thrombosis & Hemostasis Societies of North America.

“We all know that the direct oral anticoagulants – the DOACs – are an advance over vitamin K antagonists,” said Dr. Weitz, professor of medicine and biochemistry at McMaster University, Hamilton, Ontario.

Not only are DOACs at least as effective as vitamin K antagonists such as warfarin for stroke prevention in atrial fibrillation or for treatment of venous thromboembolism (VTE), but they also reduce intracranial bleeding and major bleeding risk in those settings, respectively, and they are more convenient to administer because they can be delivered using fixed doses without the need for coagulation monitoring, he added.

Still, new targets are needed, he said, explaining that, although DOACs moved closer to the goal of attenuating thrombosis without increasing the risk of bleeding, annual rates of major bleeding remain at 2%-3% in the atrial fibrillation population, and rates of major and clinically relevant nonmajor bleeding are about 10%.

“The fear of bleeding leads to underuse of anticoagulants for eligible patients with atrial fibrillation and inappropriate use of low-dose [non–vitamin K antagonist oral anticoagulant] regimens, which can leave patients unprotected from thrombotic complications,” he said.
 

Factor XI

That’s where Factor XI (FXI) may come in, Dr. Weitz said.

Current anticoagulants target enzymes, including FXa or thrombin, in the common pathway of coagulation, but the intrinsic pathway at the level of FXI and FXII has attracted attention in recent years.

The intrinsic pathway is activated when blood comes into contact with medical devices like stents, mechanical heart valves, or central venous catheters, but evidence also suggests that it plays a role in clot stabilization and growth, he explained, noting additional evidence of attenuation of thrombosis in mice deficient in FXI or FXII and in animals with FXI or FXII inhibitors.

“There is no bleeding with congenital FXII deficiency, and patients with FXI deficiency rarely have spontaneous bleeding, although they can bleed with surgery or trauma,” he noted. “Therefore, the promise of contact pathway inhibition is that we can attenuate thrombosis with little or no disruption of hemostasis.”

The initiators of the intrinsic pathway are naturally occurring polyphosphates that can activate FXI and FXII, promote platelet activation, and lead to thrombosis. A number of agents are being investigated to target these enzymes – particularly FXI, for which the strongest epidemiological and other evidence of its link with thrombosis exists. He noted that FXI deficiency appears protective against deep-vein thrombosis (DVT) and ischemic stroke, whereas high levels are linked with an increased risk of venous and arterial thrombosis.

Investigative strategies include the use of antisense oligonucleotides to reduce hepatic synthesis of FXI, aptamers to bind FXI and block its activity, antibodies to bind FXI and block its activation or activity, and small molecules to bind reversibly to the active site of FXI and block its activity “much like the DOACs block the activity of FXa or thrombin.”

“We have to remember that the DOACs have taken over from vitamin K antagonists, like warfarin, for many indications, and as they go generic their uptake will increase even further,” Dr. Weitz said. “When we compare the FXI inhibitors with existing anticoagulants, we don’t necessarily want to go up against the DOACs – we’re looking for indications where [DOACs] have yet to be tested or may be unsafe.”

Potential indications include the following:

Prevention of major adverse cardiovascular events in patients with end-stage renal disease with or without atrial fibrillation.

Provision of a safer platform for antiplatelet therapy in patients with acute coronary syndrome.

Secondary stroke prevention.

Prevention or treatment of cancer-associated VTE.

Prevention of thrombosis associated with central venous catheters, left ventricular assist devices, or mechanical heart valves.

Agents in development

Of the FXI inhibitors in development, ISIS-FXI_Rx, an antisense oligonucleotide against FXI, is furthest along. In a study published in Blood, ISIS-FXI_Rx produced a dose-dependent and sustained reduction in FXI levels in healthy volunteers, and in a later randomized study published in The New England Journal of Medicine, it significantly reduced the incidence of DVT in patients undergoing voluntary total knee arthroplasty (30.4% with enoxaparin vs. 4.2% with ISIS-FXI_Rx at a dose of 300 mg). Bleeding rates were 8.3% and 2.6%, respectively.

The findings showed the potential for reducing thrombosis without increasing bleeding by targeting FXI, Dr. Weitz said, adding that ISIS-FXIR_x was also evaluated in a small study of patients with end-stage renal disease undergoing hemodialysis and was shown to produce a dose-dependent reduction in FXI levels and to reduce the incidence of category 3 and 4 clotting in the air trap and dialyzer, compared with placebo, when given in addition to heparin.

This suggests that FXI knockdown can attenuate device-associated clotting to a greater extent than heparin alone, Dr. Weitz said.

The FXIa-directed inhibitory antibody osocimab has also been evaluated in both healthy volunteers and in patients undergoing total knee arthroplasty. In a 2019 study of healthy volunteers, a single IV injection showed a dose-dependent pharmacokinetic profile and produced FXI inhibition for about 1 month, and in the FOXTROT trial published in January in JAMA by Dr. Weitz and colleagues, osocimab was shown to reduce the incidence of symptomatic VTE, asymptomatic DVT, and VTE-related death up to day 10-13 after total knee arthroplasty.

Osocimab at doses ranging from 0.3-1.8 mg/kg given postoperatively or preoperatively were noninferior to enoxaparin (rates of 15.7%-23.7% vs. 26.3%), and osocimab at a preoperative dose of 1.8 mg/kg was superior to both enoxaparin and apixaban (11.5% vs. 26.3% and 14.5%, respectively), he said.

Bleeding rates ranged from 0%-5% with osocimab, compared with 6% with enoxaparin and 2% with apixaban
 

Ongoing studies

Currently ongoing studies of FXI-directed anticoagulation strategies include a study comparing ISIS-FXI_Rx with placebo in 200 patients with end-stage renal disease, a study comparing osocimab with placebo in 600 patients with end-stage renal disease, and a study comparing abelacimab – an antibody that binds to FXI and prevents its activation by either FXIIa or thrombin, with enoxaparin in 700 patients undergoing total knee arthroplasty, Dr. Weitz said.

Additionally, there is “considerable activity” with small molecule inhibitors of FXIa, including a phase 2, placebo-controlled, dose-ranging study looking at the novel JNG-7003/BMS-986177 agent for secondary stroke/transient ischemic attack prevention in 2,500 patients and a phase 2 study comparing it with enoxaparin for postoperative thromboprophylaxis in 1,200 patients undergoing total knee arthroplasty.

Parallel phase 2 studies are also underway to compare the novel BAY-2433334 small molecule inhibitor with placebo for stroke/transient ischemic attack prevention, with apixaban for atrial fibrillation, and for prevention of major adverse cardiovascular events in patients with acute MI.

These ongoing trials will help determine the risk-benefit profile of FXI inhibitors he said.

Session comoderator Anne Rose, PharmD, pharmacy coordinator at the University of Wisconsin, Madison, noted that these types of agents have been discussed “for quite some time” and asked whether they will be available for use in clinical practice in the near future.

Dr. Weitz predicted it will be at least a few years. The studies are just now moving to phase 2b and will still need to be evaluated in phase 3 trials and for appropriate new indications, he said.

Factor XI has emerged as a promising target for new anticoagulants, and several strategies for inhibiting the enzyme to reduce stroke, thromboembolism, and bleeding risk are under investigation, according to Jeffrey I. Weitz, MD.

These strategies could pick up where direct-acting oral anticoagulants leave off, he suggested during a presentation at the biennial summit of the Thrombosis & Hemostasis Societies of North America.

“We all know that the direct oral anticoagulants – the DOACs – are an advance over vitamin K antagonists,” said Dr. Weitz, professor of medicine and biochemistry at McMaster University, Hamilton, Ontario.

Not only are DOACs at least as effective as vitamin K antagonists such as warfarin for stroke prevention in atrial fibrillation or for treatment of venous thromboembolism (VTE), but they also reduce intracranial bleeding and major bleeding risk in those settings, respectively, and they are more convenient to administer because they can be delivered using fixed doses without the need for coagulation monitoring, he added.

Still, new targets are needed, he said, explaining that, although DOACs moved closer to the goal of attenuating thrombosis without increasing the risk of bleeding, annual rates of major bleeding remain at 2%-3% in the atrial fibrillation population, and rates of major and clinically relevant nonmajor bleeding are about 10%.

“The fear of bleeding leads to underuse of anticoagulants for eligible patients with atrial fibrillation and inappropriate use of low-dose [non–vitamin K antagonist oral anticoagulant] regimens, which can leave patients unprotected from thrombotic complications,” he said.
 

Factor XI

That’s where Factor XI (FXI) may come in, Dr. Weitz said.

Current anticoagulants target enzymes, including FXa or thrombin, in the common pathway of coagulation, but the intrinsic pathway at the level of FXI and FXII has attracted attention in recent years.

The intrinsic pathway is activated when blood comes into contact with medical devices like stents, mechanical heart valves, or central venous catheters, but evidence also suggests that it plays a role in clot stabilization and growth, he explained, noting additional evidence of attenuation of thrombosis in mice deficient in FXI or FXII and in animals with FXI or FXII inhibitors.

“There is no bleeding with congenital FXII deficiency, and patients with FXI deficiency rarely have spontaneous bleeding, although they can bleed with surgery or trauma,” he noted. “Therefore, the promise of contact pathway inhibition is that we can attenuate thrombosis with little or no disruption of hemostasis.”

The initiators of the intrinsic pathway are naturally occurring polyphosphates that can activate FXI and FXII, promote platelet activation, and lead to thrombosis. A number of agents are being investigated to target these enzymes – particularly FXI, for which the strongest epidemiological and other evidence of its link with thrombosis exists. He noted that FXI deficiency appears protective against deep-vein thrombosis (DVT) and ischemic stroke, whereas high levels are linked with an increased risk of venous and arterial thrombosis.

Investigative strategies include the use of antisense oligonucleotides to reduce hepatic synthesis of FXI, aptamers to bind FXI and block its activity, antibodies to bind FXI and block its activation or activity, and small molecules to bind reversibly to the active site of FXI and block its activity “much like the DOACs block the activity of FXa or thrombin.”

“We have to remember that the DOACs have taken over from vitamin K antagonists, like warfarin, for many indications, and as they go generic their uptake will increase even further,” Dr. Weitz said. “When we compare the FXI inhibitors with existing anticoagulants, we don’t necessarily want to go up against the DOACs – we’re looking for indications where [DOACs] have yet to be tested or may be unsafe.”

Potential indications include the following:

Prevention of major adverse cardiovascular events in patients with end-stage renal disease with or without atrial fibrillation.

Provision of a safer platform for antiplatelet therapy in patients with acute coronary syndrome.

Secondary stroke prevention.

Prevention or treatment of cancer-associated VTE.

Prevention of thrombosis associated with central venous catheters, left ventricular assist devices, or mechanical heart valves.

Agents in development

Of the FXI inhibitors in development, ISIS-FXI_Rx, an antisense oligonucleotide against FXI, is furthest along. In a study published in Blood, ISIS-FXI_Rx produced a dose-dependent and sustained reduction in FXI levels in healthy volunteers, and in a later randomized study published in The New England Journal of Medicine, it significantly reduced the incidence of DVT in patients undergoing voluntary total knee arthroplasty (30.4% with enoxaparin vs. 4.2% with ISIS-FXI_Rx at a dose of 300 mg). Bleeding rates were 8.3% and 2.6%, respectively.

The findings showed the potential for reducing thrombosis without increasing bleeding by targeting FXI, Dr. Weitz said, adding that ISIS-FXIR_x was also evaluated in a small study of patients with end-stage renal disease undergoing hemodialysis and was shown to produce a dose-dependent reduction in FXI levels and to reduce the incidence of category 3 and 4 clotting in the air trap and dialyzer, compared with placebo, when given in addition to heparin.

This suggests that FXI knockdown can attenuate device-associated clotting to a greater extent than heparin alone, Dr. Weitz said.

The FXIa-directed inhibitory antibody osocimab has also been evaluated in both healthy volunteers and in patients undergoing total knee arthroplasty. In a 2019 study of healthy volunteers, a single IV injection showed a dose-dependent pharmacokinetic profile and produced FXI inhibition for about 1 month, and in the FOXTROT trial published in January in JAMA by Dr. Weitz and colleagues, osocimab was shown to reduce the incidence of symptomatic VTE, asymptomatic DVT, and VTE-related death up to day 10-13 after total knee arthroplasty.

Osocimab at doses ranging from 0.3-1.8 mg/kg given postoperatively or preoperatively were noninferior to enoxaparin (rates of 15.7%-23.7% vs. 26.3%), and osocimab at a preoperative dose of 1.8 mg/kg was superior to both enoxaparin and apixaban (11.5% vs. 26.3% and 14.5%, respectively), he said.

Bleeding rates ranged from 0%-5% with osocimab, compared with 6% with enoxaparin and 2% with apixaban
 

Ongoing studies

Currently ongoing studies of FXI-directed anticoagulation strategies include a study comparing ISIS-FXI_Rx with placebo in 200 patients with end-stage renal disease, a study comparing osocimab with placebo in 600 patients with end-stage renal disease, and a study comparing abelacimab – an antibody that binds to FXI and prevents its activation by either FXIIa or thrombin, with enoxaparin in 700 patients undergoing total knee arthroplasty, Dr. Weitz said.

Additionally, there is “considerable activity” with small molecule inhibitors of FXIa, including a phase 2, placebo-controlled, dose-ranging study looking at the novel JNG-7003/BMS-986177 agent for secondary stroke/transient ischemic attack prevention in 2,500 patients and a phase 2 study comparing it with enoxaparin for postoperative thromboprophylaxis in 1,200 patients undergoing total knee arthroplasty.

Parallel phase 2 studies are also underway to compare the novel BAY-2433334 small molecule inhibitor with placebo for stroke/transient ischemic attack prevention, with apixaban for atrial fibrillation, and for prevention of major adverse cardiovascular events in patients with acute MI.

These ongoing trials will help determine the risk-benefit profile of FXI inhibitors he said.

Traditional delivery of palliative care to outpatients with cancer is associated with many challenges.

Telehealth can eliminate some of these challenges but comes with issues of its own, according to results of the REACH PC trial.

Jennifer S. Temel, MD, of Massachusetts General Hospital in Boston, discussed the use of telemedicine in palliative care, including results from REACH PC, during an educational session at the ASCO Virtual Quality Care Symposium 2020.

Dr. Temel noted that, for cancer patients, an in-person visit with a palliative care specialist can cost time, induce fatigue, and increase financial burden from transportation and parking expenses.

For caregivers and family, an in-person visit may necessitate absence from family and/or work, require complex scheduling to coordinate with other office visits, and result in additional transportation and/or parking expenses.

For health care systems, to have a dedicated palliative care clinic requires precious space and financial expenditures for office personnel and other resources.

These issues make it attractive to consider whether telehealth could be used for palliative care services.
 

Scarcity of palliative care specialists

In the United States, there is roughly 1 palliative care physician for every 20,000 older adults with a life-limiting illness, according to research published in Annual Review of Public Health in 2014.

In its 2019 state-by-state report card, the Center to Advance Palliative Care noted that only 72% of U.S. hospitals with 50 or more beds have a palliative care team.

For patients with serious illnesses and those who are socioeconomically or geographically disadvantaged, palliative care is often inaccessible.

Inefficiencies in the current system are an additional impediment. Palliative care specialists frequently see patients during a portion of the patient’s routine visit to subspecialty or primary care clinics. This limits the palliative care specialist’s ability to perform comprehensive assessments and provide patient-centered care efficiently.
 

Special considerations regarding telehealth for palliative care

As a specialty, palliative care involves interactions that could make the use of telehealth problematic. For example, conveyance of interest, warmth, and touch are challenging or impossible in a video format.

Palliative care specialists engage with patients regarding relatively serious topics such as prognosis and end-of-life preferences. There is uncertainty about how those discussions would be received by patients and their caregivers via video.

Furthermore, there are logistical impediments such as prescribing opioids with video or across state lines.

Despite these concerns, the ENABLE study showed that supplementing usual oncology care with weekly (transitioning to monthly) telephone-based educational palliative care produced higher quality of life and mood than did usual oncology care alone. These results were published in JAMA in 2009.
 

REACH PC study demonstrates feasibility of telehealth model

Dr. Temel described the ongoing REACH PC trial in which palliative care is delivered via video visits and compared with in-person palliative care for patients with advanced non–small cell lung cancer.

The primary aim of REACH PC is to determine whether telehealth palliative care is equivalent to traditional palliative care in improving quality of life as a supplement to routine oncology care.

Currently, REACH PC has enrolled 581 patients at its 20 sites, spanning a geographically diverse area. Just over half of patients approached about REACH PC agreed to enroll in it. Ultimately, 1,250 enrollees are sought.

Among patients who declined to participate, 7.6% indicated “discomfort with technology” as the reason. Most refusals were due to lack of interest in research (35.1%) and/or palliative care (22.9%).

Older adults were prominent among enrollees. More than 60% were older than 60 years of age, and more than one-third were older than 70 years.

Among patients who began the trial, there were slightly more withdrawals in the telehealth participants, in comparison with in-person participants (13.6% versus 9.1%).

When palliative care clinicians were queried about video visits, 64.3% said there were no challenges. This is comparable to the 65.5% of clinicians who had no challenges with in-person visits.

When problems occurred with video visits, they were most frequently technical (19.1%). Only 1.4% of clinicians reported difficulty addressing topics that felt uncomfortable over video, and 1.5% reported difficulty establishing rapport.

The success rates of video and in-person visits were similar. About 80% of visits accomplished planned goals.
 

‘Webside’ manner

Strategies such as reflective listening and summarizing what patients say (to verify an accurate understanding of the patient’s perspective) are key to successful palliative care visits, regardless of the setting.

For telehealth visits, Dr. Temel described techniques she defined as “webside manner,” to compensate for the inability of the clinician to touch a patient. These techniques include leaning in toward the camera, nodding, and pausing to be certain the patient has finished speaking before the clinician speaks again.
 

Is telehealth the future of palliative care?

I include myself among those oncologists who have voiced concern about moving from face-to-face to remote visits for complicated consultations such as those required for palliative care. Nonetheless, from the preliminary results of the REACH PC trial, it appears that telehealth could be a valuable tool.

To minimize differences between in-person and remote delivery of palliative care, practical strategies for ensuring rapport and facilitating a trusting relationship should be defined further and disseminated.

In addition, we need to be vigilant for widening inequities of care from rapid movement to the use of technology (i.e., an equity gap). In their telehealth experience during the COVID-19 pandemic, investigators at Houston Methodist Cancer Center found that patients declining virtual visits tended to be older, lower-income, and less likely to have commercial insurance. These results were recently published in JCO Oncology Practice.

For the foregoing reasons, hybrid systems for palliative care services will probably always be needed.

Going forward, we should heed the advice of Alvin Toffler in his book Future Shock. Mr. Toffler said, “The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.”

The traditional model for delivering palliative care will almost certainly need to be reimagined and relearned.

These techniques include leaning in toward the camera, nodding, and pausing to be certain the patient has finished speaking before the clinician speaks again.
 

Is telehealth the future of palliative care?

I include myself among those oncologists who have voiced concern about moving from face-to-face to remote visits for complicated consultations such as those required for palliative care. Nonetheless, from the preliminary results of the REACH PC trial, it appears that telehealth could be a valuable tool.

To minimize differences between in-person and remote delivery of palliative care, practical strategies for ensuring rapport and facilitating a trusting relationship should be defined further and disseminated.

In addition, we need to be vigilant for widening inequities of care from rapid movement to the use of technology (i.e., an equity gap). In their telehealth experience during the COVID-19 pandemic, investigators at Houston Methodist Cancer Center found that patients declining virtual visits tended to be older, lower-income, and less likely to have commercial insurance. These results were recently published in JCO Oncology Practice.

For the foregoing reasons, hybrid systems for palliative care services will probably always be needed.

Going forward, we should heed the advice of Alvin Toffler in his book Future Shock. Mr. Toffler said, “The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.”

The traditional model for delivering palliative care will almost certainly need to be reimagined and relearned.

Dental extractions can cause significant risk of bleeding in hemophilia patients being treated with factor replacements. However, mouth splints significantly decreased the risk of postextraction bleeding in these patients, according to Takahiro Yagyuu, DDS, of the department of oral and maxillofacial surgery, Nara Medical University, Kashihara, Japan, and colleagues.

The researchers performed a retrospective analysis of the medical records of hemophilia patients who underwent tooth extraction(s) between April 2006 and April 2019 at a single university hospital in Japan.

They conducted logistic regression analyses to identify risk/protective factors for postextraction bleeding in procedures involving patients receiving factor replacement therapy. Postextraction bleeding was defined as bleeding that could not be stopped by biting down on gauze and required medical treatment between 30 minutes and 14 days after the extraction, according to the report published online on in the British Journal of Oral & Maxillofacial Surgery.

A total of 130 extractions in 48 patients with hemophilia A and 21 extractions in 7 patients with hemophilia B were performed. Postextraction bleeding events were observed in 9 patients (16.3%) and 12 extractions (7.9%). On average, postextraction bleeding occurred 6 days after intervention and on the fifth postoperative day for extractions, according to the researchers.
 

Benefits of splints

The study found that the use of mouth splints significantly decreased the risk of postextraction bleeding (odds ratio, 0.13; P = .01) in hemophilia patients being treated with clotting factor replacements.

However, other factors in the study cohort, such as age, severity of hemophilia, duration of factor replacement therapy, gingival incision, bone removal, tooth separation, use of absorbable hemostats, wound closure, and the prescription of NSAIDs, were not significantly associated with postextraction bleeding, the researchers added.

“The use of mouth splints significantly decreased the risk of post-extraction bleeding. [In the future], we will conduct a prospective study to investigate the optimal type of splint and splint-wearing period to improve hemostatic management of tooth extraction in hemophilia patients,” the researchers concluded.

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.

Major thromboembolic complications and adverse cardiovascular events occurred with high frequency in patients with COVID-19, especially in the intensive care setting, despite a high use of thromboprophylaxis, in a new large observational U.S. study.

“Despite very high rate of antithrombotic prophylaxis there were a high rate of thromboembolic events suggesting that we are probably not providing enough thromboprophylaxis,” lead author Gregory Piazza, MD, Brigham and Women’s Hospital, Boston, said in an interview. 

“Standard prophylaxis as recommended in the guidelines is a low dose of low-molecular-weight heparin once daily, but these results suggest [patients] probably need higher doses,” he added.

However, Dr. Piazza cautioned that this is an observational study and randomized trials are needed to make changes in treatment strategies. Several such trials are currently underway.

The current study was published online ahead of print in the Nov. 3 issue of the Journal of the American College of Cardiology.
 

Rates similar to other very sick patients

The study showed that while thromboembolic complications were high, they were not as high as seen in some of the earlier studies from Asia and Europe, Dr. Piazza noted.

“The numbers we were seeing in early reports were so high we couldn’t figure out how that was possible,” he said. “Our study suggests that, in a U.S. population receiving thromboprophylaxis, the rate of thromboembolic complications [are] more in line with what we would expect to see in other very sick patients who end up in ICU.”

He suggested that the very high rates of thromboembolic complications in the early studies from Asia may have been because of the lack of thromboprophylaxis, which is not routine in hospitalized patients there. “Some of the earlier studies also used routine ultrasound and so picked up asymptomatic thrombotic events, which was not the case in our study. So our results are more representative of the U.S. population.”

Dr. Piazza attributed the high rate of thromboembolic complications being reported with COVID-19 to the sheer number of very sick patients being admitted to the hospital.

“We are accustomed to seeing a rare case of thrombosis despite prophylaxis in hospitalized patients, but we are seeing more in COVID patients. This is probably just because we have more critically ill patients,” he said.

“We are seeing an incredible influx of patients to the ICU that we have never experienced before, so the increase in thromboembolic complications is more obvious. In prior years we probably haven’t had enough critically ill patients at any one time to raise the flag about thromboprophylaxis,” he commented.

The study also found a high rate of cardiovascular complications. They are seeing an increase in the risk of MI, which is to be expected in such sick patients, but they also see quite a bit of new atrial fibrillation, myocarditis, and heart failure in patients who don’t always have underlying cardiovascular disease, he said.

“So this virus does appear to have a predilection to causing cardiovascular complications, but this is probably because it is making patients so sick,” Dr. Piazza said. “If flu was this virulent and resulted in such high rates of acute respiratory distress syndrome (ARDS), we would probably see similar cardiovascular complication rates.”

For the current report, the researchers analyzed a retrospective cohort of 1,114 patients with COVID-19 diagnosed through the Mass General Brigham integrated health network. Of these, 170 had been admitted to the ICU, 229 had been hospitalized but not treated in ICU, and 715 were outpatients. In terms of ethnicity, 22% were Hispanic/Latino and 44% were non-White. 

Cardiovascular risk factors were common, with 36% of patients having hypertension, 29% hyperlipidemia, and 18% diabetes. Prophylactic anticoagulation was prescribed in 89% of patients with COVID-19 in the intensive care cohort and 85% of those in the hospitalized non–intensive care setting.

Results showed that major arterial or venous thromboembolism (VTE) occurred in 35% of the intensive care cohort, 2.6% of those hospitalized but not treated in ICU, and 0% of outpatients.

Major adverse cardiovascular events occurred in 46% of the intensive care cohort, 6.1% of those hospitalized but non-ICU, and 0% of outpatients.

Symptomatic VTE occurred in 27% of those admitted to ICU, 2.2% of those hospitalized but non-ICU, and 0% of outpatients.

“We found that outpatients had a very low rate of thromboembolic complications, with the vast majority of the risk being in hospitalized patients, especially those in ICU,” Dr. Piazza said.

“These results suggest that we don’t need routine thromboprophylaxis for all outpatients with COVID-19, but there will probably be some patients who need it – those with risk factors for thromboembolism.”

Catheter- and device-associated deep vein thrombosis accounted for 76.9% of the DVTs observed in the study.

“Our finding of high frequency of catheter-associated DVT supports the judicious use of central venous catheters that have been widely implemented, especially in the ICU, to minimize recurrent health care team exposure and facilitate monitoring,” the researchers wrote.
 

ARDS biggest risk factor

Of all the markers of disease severity, the presence of ARDS had the strongest association with adverse outcomes, including major arterial or VTE, major adverse cardiovascular events, symptomatic VTE, and death.

“The severe inflammatory state associated with ARDS and other complications of COVID-19 and its resultant hypercoagulability may explain, at least in part, the high frequency of thromboembolic events. Improved risk stratification, utilizing biochemical markers of inflammation and activated coagulation as well as clinical indicators, such as ARDS, may play an important role in the early identification of patients with an increased likelihood of developing symptomatic VTE or arterial thrombosis,” the researchers wrote. “They may benefit from full- or intermediate-intensity antithrombotic therapy rather than prophylactic anticoagulation.”

They point out that this study provides a cross-sectional view of the cardiovascular complications of COVID-19 in a large health care network, consisting of two academic medical centers serving the greater Boston area, several community hospitals, and numerous outpatient care sites.

“The study incorporates a wide scope of clinically meaningful cardiovascular endpoints and utilizes a rigorous process of event adjudication. Although data on patients with COVID-19 in the ICU have been the subject of most reports, our study provides insights into the broad spectrum of all hospitalized and outpatient populations,” the authors noted.

“The high frequency of arterial or venous thromboembolism in hospitalized patients despite routine thromboprophylaxis suggests the need for improved risk stratification and enhanced preventive efforts,” they concluded.

The study is continuing, and the researchers expect to have data on 10,000 patients by the end of winter.
 

Wait for randomized trials

In an accompanying editorial, Robert McBane, MD, Mayo Clinic, Rochester, Minn., said that these data provide important real-world arterial and venous thrombotic event rates across a large, integrated health care network and an experienced roster of clinician-scientists devoted to thrombosis research.

Noting that whether to interpret these results as alarming or reassuring requires a comparison of expected thromboembolic event rates separate from the pandemic, he pointed out that, while the overall VTE rate among ICU patients was high, the vast majority of these events were attributable to central venous lines, and apart from these, the event rates do not appear inflated relative to prior published incidence rates from the pre–COVID-19 era.

“It is therefore important to resist the urge to overprevent or overtreat patients and expose them to the serious risks of major bleeding,” Dr. McBane wrote, adding that “the systematized approach to delivery of guideline-driven VTE prophylaxis across this large, integrated health network likely contributed to the relatively low rates of serious thrombotic outcomes reported.”

He further noted that, as the majority of VTE events were related to central venous lines in ICU patients, “this underscores the importance of a bundled care approach to central venous line management with daily assessment of the continued necessity of central access.

“A number of important clinical trials aimed at optimizing thromboprophylaxis during hospitalization, following hospital dismissal, and in ambulatory settings are underway. Until available, the lessons of thoughtful anticoagulant prophylaxis and treatment guidelines harvested from years of clinical research appear to apply,” he concluded.

This study was funded, in part, by a research grant from Janssen Pharmaceuticals. Dr. Piazza has received research grant support from EKOS Corporation, Bayer, Bristol-Myers Squibb/Pfizer, Portola Pharmaceuticals, and Janssen Pharmaceuticals; and has received consulting fees from Amgen, Pfizer, Boston Scientific, Agile, and Thrombolex. Dr. McBane reported no relevant disclosures.

Noting that whether to interpret these results as alarming or reassuring requires a comparison of expected thromboembolic event rates separate from the pandemic, he pointed out that, while the overall VTE rate among ICU patients was high, the vast majority of these events were attributable to central venous lines, and apart from these, the event rates do not appear inflated relative to prior published incidence rates from the pre–COVID-19 era.

“It is therefore important to resist the urge to overprevent or overtreat patients and expose them to the serious risks of major bleeding,” Dr. McBane wrote, adding that “the systematized approach to delivery of guideline-driven VTE prophylaxis across this large, integrated health network likely contributed to the relatively low rates of serious thrombotic outcomes reported.”

He further noted that, as the majority of VTE events were related to central venous lines in ICU patients, “this underscores the importance of a bundled care approach to central venous line management with daily assessment of the continued necessity of central access.

“A number of important clinical trials aimed at optimizing thromboprophylaxis during hospitalization, following hospital dismissal, and in ambulatory settings are underway. Until available, the lessons of thoughtful anticoagulant prophylaxis and treatment guidelines harvested from years of clinical research appear to apply,” he concluded.

This study was funded, in part, by a research grant from Janssen Pharmaceuticals. Dr. Piazza has received research grant support from EKOS Corporation, Bayer, Bristol-Myers Squibb/Pfizer, Portola Pharmaceuticals, and Janssen Pharmaceuticals; and has received consulting fees from Amgen, Pfizer, Boston Scientific, Agile, and Thrombolex.

Major thromboembolic complications and adverse cardiovascular events occurred with high frequency in patients with COVID-19, especially in the intensive care setting, despite a high use of thromboprophylaxis, in a new large observational U.S. study.

“Despite very high rate of antithrombotic prophylaxis there were a high rate of thromboembolic events suggesting that we are probably not providing enough thromboprophylaxis,” lead author Gregory Piazza, MD, Brigham and Women’s Hospital, Boston, said in an interview. 

“Standard prophylaxis as recommended in the guidelines is a low dose of low-molecular-weight heparin once daily, but these results suggest [patients] probably need higher doses,” he added.

However, Dr. Piazza cautioned that this is an observational study and randomized trials are needed to make changes in treatment strategies. Several such trials are currently underway.

The current study was published online ahead of print in the Nov. 3 issue of the Journal of the American College of Cardiology.
 

Rates similar to other very sick patients

The study showed that while thromboembolic complications were high, they were not as high as seen in some of the earlier studies from Asia and Europe, Dr. Piazza noted.

“The numbers we were seeing in early reports were so high we couldn’t figure out how that was possible,” he said. “Our study suggests that, in a U.S. population receiving thromboprophylaxis, the rate of thromboembolic complications [are] more in line with what we would expect to see in other very sick patients who end up in ICU.”

He suggested that the very high rates of thromboembolic complications in the early studies from Asia may have been because of the lack of thromboprophylaxis, which is not routine in hospitalized patients there. “Some of the earlier studies also used routine ultrasound and so picked up asymptomatic thrombotic events, which was not the case in our study. So our results are more representative of the U.S. population.”

Dr. Piazza attributed the high rate of thromboembolic complications being reported with COVID-19 to the sheer number of very sick patients being admitted to the hospital.

“We are accustomed to seeing a rare case of thrombosis despite prophylaxis in hospitalized patients, but we are seeing more in COVID patients. This is probably just because we have more critically ill patients,” he said.

“We are seeing an incredible influx of patients to the ICU that we have never experienced before, so the increase in thromboembolic complications is more obvious. In prior years we probably haven’t had enough critically ill patients at any one time to raise the flag about thromboprophylaxis,” he commented.

The study also found a high rate of cardiovascular complications. They are seeing an increase in the risk of MI, which is to be expected in such sick patients, but they also see quite a bit of new atrial fibrillation, myocarditis, and heart failure in patients who don’t always have underlying cardiovascular disease, he said.

“So this virus does appear to have a predilection to causing cardiovascular complications, but this is probably because it is making patients so sick,” Dr. Piazza said. “If flu was this virulent and resulted in such high rates of acute respiratory distress syndrome (ARDS), we would probably see similar cardiovascular complication rates.”

For the current report, the researchers analyzed a retrospective cohort of 1,114 patients with COVID-19 diagnosed through the Mass General Brigham integrated health network. Of these, 170 had been admitted to the ICU, 229 had been hospitalized but not treated in ICU, and 715 were outpatients. In terms of ethnicity, 22% were Hispanic/Latino and 44% were non-White. 

Cardiovascular risk factors were common, with 36% of patients having hypertension, 29% hyperlipidemia, and 18% diabetes. Prophylactic anticoagulation was prescribed in 89% of patients with COVID-19 in the intensive care cohort and 85% of those in the hospitalized non–intensive care setting.

Results showed that major arterial or venous thromboembolism (VTE) occurred in 35% of the intensive care cohort, 2.6% of those hospitalized but not treated in ICU, and 0% of outpatients.

Major adverse cardiovascular events occurred in 46% of the intensive care cohort, 6.1% of those hospitalized but non-ICU, and 0% of outpatients.

Symptomatic VTE occurred in 27% of those admitted to ICU, 2.2% of those hospitalized but non-ICU, and 0% of outpatients.

“We found that outpatients had a very low rate of thromboembolic complications, with the vast majority of the risk being in hospitalized patients, especially those in ICU,” Dr. Piazza said.

“These results suggest that we don’t need routine thromboprophylaxis for all outpatients with COVID-19, but there will probably be some patients who need it – those with risk factors for thromboembolism.”

Catheter- and device-associated deep vein thrombosis accounted for 76.9% of the DVTs observed in the study.

“Our finding of high frequency of catheter-associated DVT supports the judicious use of central venous catheters that have been widely implemented, especially in the ICU, to minimize recurrent health care team exposure and facilitate monitoring,” the researchers wrote.
 

ARDS biggest risk factor

Of all the markers of disease severity, the presence of ARDS had the strongest association with adverse outcomes, including major arterial or VTE, major adverse cardiovascular events, symptomatic VTE, and death.

“The severe inflammatory state associated with ARDS and other complications of COVID-19 and its resultant hypercoagulability may explain, at least in part, the high frequency of thromboembolic events. Improved risk stratification, utilizing biochemical markers of inflammation and activated coagulation as well as clinical indicators, such as ARDS, may play an important role in the early identification of patients with an increased likelihood of developing symptomatic VTE or arterial thrombosis,” the researchers wrote. “They may benefit from full- or intermediate-intensity antithrombotic therapy rather than prophylactic anticoagulation.”

They point out that this study provides a cross-sectional view of the cardiovascular complications of COVID-19 in a large health care network, consisting of two academic medical centers serving the greater Boston area, several community hospitals, and numerous outpatient care sites.

“The study incorporates a wide scope of clinically meaningful cardiovascular endpoints and utilizes a rigorous process of event adjudication. Although data on patients with COVID-19 in the ICU have been the subject of most reports, our study provides insights into the broad spectrum of all hospitalized and outpatient populations,” the authors noted.

“The high frequency of arterial or venous thromboembolism in hospitalized patients despite routine thromboprophylaxis suggests the need for improved risk stratification and enhanced preventive efforts,” they concluded.

The study is continuing, and the researchers expect to have data on 10,000 patients by the end of winter.

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.

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.”
