Half of Chinese American parents and their children report having experienced an in-person episode of racial discrimination related to the COVID-19 pandemic, according to results from a survey study.

In the United States, where public officials continue to refer to SARS-CoV-2 as the “China virus” and have often sought to draw attention to its origins in Wuhan, China, “the associations between discrimination triggered by the racialization of this acute public health crisis and mental health are unknown,” Charissa S.L. Cheah, PhD, of the University of Maryland, Baltimore County, and colleagues wrote.

For their research published Oct. 29 in Pediatrics, Dr. Cheah and colleagues recruited a cohort of 543 Chinese American parents of school-age children, and 230 of their children aged 10-18 years, to complete online surveys between mid-March and late May 2020. Parents in the cohort were largely foreign born, with all identifying as ethnically Chinese, while their children were mostly U.S. born.
 

Evidence of discrimination against Chinese Americans

Half of parents and their children (51% of parents and 50% of youth) reported experiencing at least one in-person incident of direct discrimination (assessed using questions derived from a validated scale of racial aggression) related to the pandemic. Dr. Cheah and colleagues also reported a high incidence of direct discrimination online (32% of parents and 46% of youth). Additionally, the researchers measured reports of vicarious or indirect discrimination – such as hearing jokes or disparaging remarks about one’s ethnic group – which they used a different adapted scale to capture. More than three-quarters of the cohort reported such experiences.

The experiences of discrimination likely bore on the mental health of both parents and youth. Using a series of instruments designed to measure overall psychological well-being as well as symptoms of depression, anxiety, and certain emotional and behavioral outcomes, Dr. Cheah and colleagues reported significant negative associations between direct online or in-person discrimination and psychological health. For parents and children alike, anxiety and depressive symptoms were positively associated with all varieties of discrimination experiences measured in the study.

About a fifth of the youth in the study were deemed, based on the symptom scales used in the study, to have an elevated risk of clinically significant mental health problems, higher than the 10%-15% that would be expected for these age groups in the United States.

“This study revealed that a high percentage of Chinese American parents and their children personally experienced or witnessed anti-Chinese or anti–Asian American racial discrimination both online and in person due to the COVID-19 pandemic,” the investigators wrote. “Most respondents reported directly experiencing or witnessing racial discrimination against other Chinese or Asian American individuals due to COVID-19 at least once.”

Dr. Cheah and colleagues noted that their cross-sectional study did not lend itself to causal interpretations and was vulnerable to certain types of reporting bias. Nonetheless, they argued, as the pandemic continues, “pediatricians should be sensitive to the potential mental health needs of Chinese American youth and their parents related to various forms of racism, in addition to other stressors, as the foundations of perceptions of racial-ethnic discrimination and their consequences may be set during this period.”
 

COVID-19 didn’t only bring infection

In an accompanying editorial, Tina L. Cheng, MD, of Johns Hopkins University, Baltimore, and her daughter Alison M. Conca-Cheng, a medical student at Brown University, Providence, R.I., remarked that the study’s findings were consistent with recent research that found “4 in 10 Americans reported that it has become more common since COVID-19 for people to express racist views about Asian Americans,” and also described an increase in complaints of discriminatory experiences by Asian Americans.

In this context, a link to poor mental health “should be no surprise,” Dr. Cheng and Ms. Conca-Cheng argued, and urged pediatricians to consult the American Academy of Pediatrics’ 2019 policy statement on racism and on child and adolescent health. “It calls for us to optimize clinical practice, improve workforce development and professional education, strengthen research, and deploy systems through community engagement, advocacy, and public policy.”

David Rettew, MD, a child and adolescent psychiatrist and associate professor of psychiatry and pediatrics at the University of Vermont, Burlington, called the study’s main points “clear and disturbing.”

“While it is difficult to find much in the way here of a silver lining, these alarming reports have helped people working in health care and mental health to understand racism as another form of trauma and abuse which, like other types, can have real negative effects on health,” Dr. Rettew said in an interview. “The more we as mental health professions ask about racism and offer resources for people who have experienced it, just as we would people who have endured other types of trauma, the more we can help people heal. That said, it would be better just to stop this from happening in the first place.”

Dr. Cheah and colleagues’ study was supported by a National Science Foundation grant. The investigators disclosed no conflicts of interest. Dr. Cheng and Ms. Conca-Cheng disclosed no financial conflicts of interest related to their editorial. Dr. Rettew said he had no relevant financial disclosures.

Tocilizumab (Actemra/RoActemra) was not found to have any clear role as a treatment for COVID-19 in four new studies.

Three randomized controlled trials showed that the drug either had no benefit or only a modest one, contradicting a large retrospective study that had hinted at a more robust effect.

“This is not a blockbuster,” said David Cennimo, MD, an infectious disease expert at Rutgers New Jersey Medical School, Newark, New Jersey. “This is not something that’s going to revolutionize our treatment of COVID-19.”

But some researchers still regard these studies as showing evidence that the drug benefits certain patients with severe inflammation.

The immune response to SARS-CoV-2 includes elevated levels of the cytokine interleukin-6 (IL-6). In some patients, this response becomes a nonspecific inflammation, a “cytokine storm,” involving edema and inflammatory cell infiltration in the lungs. These cases are among the most severe.

Dexamethasone has proved effective in controlling this inflammation in some patients. Researchers have theorized that a more targeted suppression of IL-6 could be even more effective or work in cases that don’t respond to dexamethasone.

A recombinant monoclonal antibody, tocilizumab blocks IL-6 receptors. It is approved by the US Food and Drug Administration for use in patients with rheumatologic disorders and cytokine release syndrome induced by chimeric antigen receptor T-cell therapy.

Current National Institutes of Health (NIH) guidelines recommend against the use of tocilizumab as a treatment for COVID-19, despite earlier observational studies that suggested the drug might help patients with moderate to severe disease. Controlled trials were lacking until now.

The most hopeful results in this batch came from the CORIMUNO-19 platform of open-label, randomized controlled trials of immune modulatory treatments for moderate or severe COVID-19 in France.

Published in JAMA Internal Medicine , the trial recruited patients from nine French hospitals. Patients were eligible if they required at least 3 L/min of oxygen without ventilation or admission to the intensive care unit.

The investigators randomly assigned 64 patients to receive tocilizumab 8 mg/kg body weight intravenously plus usual care and 67 patients to usual care alone. Usual care included antibiotic agents, antiviral agents, corticosteroids, vasopressor support, and anticoagulants.

After 4 days, the investigators scored patients on the World Health Organization 10-point Clinical Progression Scale. Twelve of the patients who received tocilizumab scored higher than 5 vs 19 of the patients in the usual care group, with higher scores indicating clinical deterioration.

After 14 days, 24% of the patients taking tocilizumab required either noninvasive ventilation or mechanical ventilation or had died, vs 36% in the usual care group (median posterior hazard ratio [HR], 0.58; 90% credible interval, 0.33 – 1.00).

“We reduced the risk of dying or requiring mechanical ventilation, so for me, the study was positive,” said Olivier Hermine, MD, PhD, a professor of hematology at Paris Descartes University in Paris, France.

However, there was no difference in mortality at 28 days. Hermine hopes to have longer-term outcomes soon, he told Medscape Medical News.

A second randomized controlled trial, also published in JAMA Internal Medicine , provided less hope. In this RCT-TCZ-COVID-19 Study Group trial, conducted at 24 Italian centers, patients were enrolled if their partial pressure of arterial oxygen to fraction of inspired oxygen (PaO₂/FiO₂) ratios were between 200 and 300 mm Hg and if their inflammatory phenotypes were defined by fever and elevated C-reactive protein level.

The investigators randomly assigned 60 patients to receive tocilizumab 8 mg/kg up to a maximum of 800 mg within 8 hours of randomization, followed by a second dose after 12 hours. They assigned 66 patients to a control group that received supportive care until clinical worsening, at which point patients could receive tocilizumab as a rescue therapy.

Of the patients who received tocilizumab, 28.3% showed clinical worsening within 14 days, compared to 27.0% in the control group (rate ratio, 1.05; 95% CI, 0.59 – 1.86). There was no significant difference between the groups in terms of the proportion admitted to intensive care. The researchers stopped the trial prematurely because tocilizumab did not seem to be making a difference.

The BACC Bay Tocilizumab Trial was conducted at seven Boston hospitals. The results, which were published in The New England Journal of Medicine, were also discouraging.

In that trial, enrolled patients met two sets of parameters. First, the patients had at least one of the following signs: C-reactive protein level higher than 50 mg/L, ferritin level higher than 500 ng/mL, D-dimer level higher than 1000 ng/mL, or a lactate dehydrogenase level higher than 250 U/L. Second, the patients had to have at least two of the following signs: body temperature >38° C, pulmonary infiltrates, or the need for supplemental oxygen to maintain an oxygen saturation greater than 92%.

The investigators randomly assigned 161 patients to receive intravenous tocilizumab 8 mg/kg up to 800 mg and 81 to receive a placebo.

They didn’t find a statistically significant difference between the groups. The hazard ratio for intubation or death in the tocilizumab group as compared with the placebo group was 0.83 (95% CI, 0.38 – 1.81; P = .64). The hazard ratio for disease worsening was 1.11 (95% CI, 0.59 – 2.10; P = .73). At 14 days, the conditions of 18.0% of the patients who received tocilizumab and 14.9% of the patients who received the placebo worsened.

In contrast to these randomized trials, STOP-COVID, a retrospective analysis of 3924 patients, also published in JAMA Internal Medicine, found that the risk for death was lower for patients treated with tocilizumab compared with those not treated with tocilizumab (HR, 0.71; 95% CI, 0.56 – 0.92) over a median follow-up period of 27 days.

Also on the bright side, none of the new studies showed significant adverse reactions to tocilizumab.

More randomized clinical trials are underway. In press releases announcing topline data, Roche reported mostly negative results in its phase 3 COVACTA trial but noted a 44% reduction in the risk for progression to death or ventilation in its phase 3 IMPACTA trial. Roche did not comment on the ethnicity of its COVACTA patients; it said IMPACTA enrolled a majority of Hispanic patients and included large representations of Native American and Black patients.
 

Results don’t support routine use

Commenting on the new studies, editorialists in both JAMA Internal Medicine and The New England Journal of Medicine concluded that the tocilizumab results were not strong enough to support routine use.

“My take-home point from looking at all of these together is that, even if it does help, it’s most likely in a small subset of the population and/or a small effect,” Cennimo told Medscape Medical News.

But the NIH recommendation against tocilizumab goes too far, argued Cristina Mussini, MD, a professor of infectious diseases at the University of Modena and Reggio Emilia in Italy, who is a coauthor of a cohort study of tocilizumab and served on the CORIMUNO-19 Data Safety and Monitoring Board.

“I really think it’s too early to recommend against it because at least two clinical trials showed protection against mechanical ventilation and death,” she said.

She prescribes tocilizumab for patients who have not been helped by dexamethasone. “It’s just a rescue drug,” she told Medscape Medical News. “It’s not something you use for everybody, but it’s the only weapon we have now when the patient is really going to the intensive care unit.”

The BACC Bay Tocilizumab Trial was funded by Genentech/Roche. Genentech/Roche provided the drug for the CORIMUNO and RCT-TCZ-COVID-19 trials. The STOP-COVID study was supported by grants from the NIH and by the Frankel Cardiovascular Center COVID-19: Impact Research Ignitor. Cennimo, Hermine, and Mussini have disclosed no relevant financial relationships.

A second randomized controlled trial, also published in JAMA Internal Medicine , provided less hope. In this RCT-TCZ-COVID-19 Study Group trial, conducted at 24 Italian centers, patients were enrolled if their partial pressure of arterial oxygen to fraction of inspired oxygen (PaO₂/FiO₂) ratios were between 200 and 300 mm Hg and if their inflammatory phenotypes were defined by fever and elevated C-reactive protein level.

The investigators randomly assigned 60 patients to receive tocilizumab 8 mg/kg up to a maximum of 800 mg within 8 hours of randomization, followed by a second dose after 12 hours. They assigned 66 patients to a control group that received supportive care until clinical worsening, at which point patients could receive tocilizumab as a rescue therapy.

Of the patients who received tocilizumab, 28.3% showed clinical worsening within 14 days, compared to 27.0% in the control group (rate ratio, 1.05; 95% CI, 0.59 – 1.86). There was no significant difference between the groups in terms of the proportion admitted to intensive care. The researchers stopped the trial prematurely because tocilizumab did not seem to be making a difference.

The BACC Bay Tocilizumab Trial was conducted at seven Boston hospitals. The results, which were published in The New England Journal of Medicine, were also discouraging.

In that trial, enrolled patients met two sets of parameters. First, the patients had at least one of the following signs: C-reactive protein level higher than 50 mg/L, ferritin level higher than 500 ng/mL, D-dimer level higher than 1000 ng/mL, or a lactate dehydrogenase level higher than 250 U/L. Second, the patients had to have at least two of the following signs: body temperature >38° C, pulmonary infiltrates, or the need for supplemental oxygen to maintain an oxygen saturation greater than 92%.

The investigators randomly assigned 161 patients to receive intravenous tocilizumab 8 mg/kg up to 800 mg and 81 to receive a placebo.

They didn’t find a statistically significant difference between the groups. The hazard ratio for intubation or death in the tocilizumab group as compared with the placebo group was 0.83 (95% CI, 0.38 – 1.81; P = .64). The hazard ratio for disease worsening was 1.11 (95% CI, 0.59 – 2.10; P = .73). At 14 days, the conditions of 18.0% of the patients who received tocilizumab and 14.9% of the patients who received the placebo worsened.

In contrast to these randomized trials, STOP-COVID, a retrospective analysis of 3924 patients, also published in JAMA Internal Medicine, found that the risk for death was lower for patients treated with tocilizumab compared with those not treated with tocilizumab (HR, 0.71; 95% CI, 0.56 – 0.92) over a median follow-up period of 27 days.

Also on the bright side, none of the new studies showed significant adverse reactions to tocilizumab.

More randomized clinical trials are underway. In press releases announcing topline data, Roche reported mostly negative results in its phase 3 COVACTA trial but noted a 44% reduction in the risk for progression to death or ventilation in its phase 3 IMPACTA trial. Roche did not comment on the ethnicity of its COVACTA patients; it said IMPACTA enrolled a majority of Hispanic patients and included large representations of Native American and Black patients.
 

Results don’t support routine use

Commenting on the new studies, editorialists in both JAMA Internal Medicine and The New England Journal of Medicine concluded that the tocilizumab results were not strong enough to support routine use.

“My take-home point from looking at all of these together is that, even if it does help, it’s most likely in a small subset of the population and/or a small effect,” Cennimo told Medscape Medical News.

But the NIH recommendation against tocilizumab goes too far, argued Cristina Mussini, MD, a professor of infectious diseases at the University of Modena and Reggio Emilia in Italy, who is a coauthor of a cohort study of tocilizumab and served on the CORIMUNO-19 Data Safety and Monitoring Board.

“I really think it’s too early to recommend against it because at least two clinical trials showed protection against mechanical ventilation and death,” she said.

She prescribes tocilizumab for patients who have not been helped by dexamethasone. “It’s just a rescue drug,” she told Medscape Medical News. “It’s not something you use for everybody, but it’s the only weapon we have now when the patient is really going to the intensive care unit.”

The BACC Bay Tocilizumab Trial was funded by Genentech/Roche. Genentech/Roche provided the drug for the CORIMUNO and RCT-TCZ-COVID-19 trials. The STOP-COVID study was supported by grants from the NIH and by the Frankel Cardiovascular Center COVID-19: Impact Research Ignitor. Cennimo, Hermine, and Mussini have disclosed no relevant financial relationships.

Eli Lilly announced it will halt its ACTIV-3 trial evaluating the antibody bamlanivimab in combination with remdesivir for people hospitalized with COVID-19, after new evidence regarding efficacy emerged.

The new data from the National Institutes of Health suggest that the experimental neutralizing antibody therapy does not offer significant clinical benefit for people with more advanced COVID-19 illness, according to a company statement.

Eli Lilly also announced it plans to continue its other trials evaluating the antibody, including those assessing a potential role in treating people in the earlier stages of COVID-19.

“While there was insufficient evidence that bamlanivimab improved clinical outcomes when added to other treatments in hospitalized patients with COVID-19, we remain confident based on data from Lilly’s BLAZE-1 study that bamlanivimab monotherapy may prevent progression of disease for those earlier in the course of COVID-19,” the statement reads.

The ACTIV-3 trial was paused on October 13 after a data and safety monitoring board cited safety concerns.

The most recent data update that triggered an end to the trial did not reveal any significant differences in safety, though.

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.

Vertebral fractures appear to be common in people with severe COVID-19, and also raise the mortality risk, findings from a retrospective cohort suggest.

Among 114 patients with COVID-19 who underwent lateral chest x-rays at the San Raffaele Hospital ED in Milan, more than a third were found to have thoracic vertebral fractures. And, those individuals were more than twice as likely to die as were those without vertebral fractures.

“Morphometric vertebral fractures are one of the most common comorbidities among adults hospitalized with COVID-19, and the presence of such fractures may predict the severity of disease outcomes,” lead investigator Andrea Giustina, MD, said in an interview.

This is the first study to examine vertebral fracture prevalence in any coronavirus disease, but such fractures have been linked to an increased risk of pneumonia and impaired respiratory function, including restrictive pulmonary dysfunction. One possible mechanism may be that they cause anatomical changes, such as kyphosis, which negatively impact respiratory function by decreasing vital capacity, forced expiratory volume in 1 second, and inspiratory time, explained Dr. Giustina, professor of endocrinology, San Raffaele Vita Salute University, Milan, and president of the European Society of Endocrinology. The results were published in the Journal of Clinical Endocrinology and Metabolism.

Clinically, the findings suggest that all patients with COVID-19 who are undergoing chest x-rays should have morphometric vertebral x-ray evaluation, said Dr. Giustina.

“One interesting aspect of the study is that without morphometry, approximatively two thirds of vertebral fractures [would have been] missed. Therefore, they are largely underestimated in clinical practice,” he noted.
 

Thoracic vertebral fractures assessed via lateral chest x-rays

The 114 study subjects included were those whose lateral chest x-rays allowed for a high-quality assessment and in which all the thoracic tract of T4-T12 were viewable and assessable. None had been using glucocorticoids and only 3% had a prior diagnosis of osteoporosis.

The majority (75%) were male, and median age was 57 years. Most (79%) were hospitalized after evaluation in the ED. Of those, 12% (13) were admitted to the ICU and 15% (16) died.

Thoracic vertebral fractures were detected on the lateral chest x-rays in 36% (41) of the patients. In contrast, in studies of women aged 50 years and older from the general European population, morphometric vertebral fracture prevalence ranged from 18% to 26%, the investigators noted.

Of the total 65 vertebral fractures detected, 60% were classified as mild (height ratio decrease <25%), 33.3% as moderate (25%-40% decrease) and 7.7% as severe (>40%). Patients with more than one vertebral fracture were classified by their most severe one.

Those with versus without vertebral fractures didn’t differ by sex, body mass index, or clinical or biological parameters evaluated in the ED. But, compared with those without vertebral fractures, those with them were significantly older (68 vs. 54 years) and were more likely to have arterial hypertension (56% vs. 30%) and coronary artery disease (22% vs. 7%).

In multivariate analysis, age was the only statistically significant predictor of vertebral fractures (odds ratio, 1.04; P < .001).

Mortality doubled, though not significantly

Those with vertebral fractures were more likely to be hospitalized, although not significantly (88% vs. 74%). There was no significant difference in ICU admission (11% vs. 12.5%).

However, those with vertebral fractures required noninvasive mechanical ventilation significantly more often (48.8% vs. 27.4%; P = .02), and were more than twice as likely to die (22% vs. 10%; P = .07). While the difference in overall mortality wasn’t quite statistically significant, those with severe vertebral fractures were significantly more likely to die, compared with those with mild or moderate fractures (60%, 7%, 24%, respectively, for severe, moderate, and mild; P = .04), despite no significant differences in clinical or laboratory parameters.

“Our data from the field reinforce the need of implementing previously published recommendations concerning the importance of bone fragility care during the COVID pandemic with at least those patients already treated with antiosteoporotic drugs maintaining their adherence to treatments including vitamin D, which have also been suggested very recently to have no relevant predisposing effect on COVID-19,” Dr. Giustina and colleagues wrote.

Moreover, they added, “continuity of care should also include bone density monitoring despite very restricted access to clinical facilities, during the COVID-19 pandemic. Finally, all patients with fractures should start antiresorptive treatment right away, even during hospital stay.”

The authors reported having no disclosures.

Is it time to consider chimeric antigen receptor (CAR) T-cell therapy for all relapsed/refractory diffuse large B-cell lymphoma patients? Maybe not, according to Andrew Zelenetz, MD, PhD.

CAR T-cell therapy has demonstrated activity in relapsed/refractory non-Hodgkin lymphoma (NHL), including diffuse large B-cell lymphoma (DLBCL), transformed indolent NHL, and mantle cell lymphoma, and can provide durable complete responses in a portion of patients with chemorefractory disease, Dr. Zelenetz, chair of the National Comprehensive Cancer Network Lymphoma Guidelines Panel and a specialist in lymphoma at Memorial Sloan Kettering Cancer Center in New York, said at the NCCN Hematologic Malignancies Annual Congress.

In chemosensitive patients, however, its role requires further examination, especially given findings from a recent analysis of patients from the Center for International Blood & Marrow Transplant Research (CIBMTR) registry showing comparable outcomes with high-dose chemotherapy and autologous stem cell rescue for patients with a positron emission testing–positive partial response (PR) after second-line chemotherapy, he said.

Of 249 patients who underwent a first autologous transplant for DLBCL between 2003 and 2018, received front-line rituximab chemotherapy, and had PET– or computed tomography–positive disease prior to transplant, 182 had early chemotherapy failure (within 12 months) and 67 had late chemotherapy failure (at 12 months or later) after therapy, according to findings from the study as reported at ASCO 2020.

The adjusted nonrelapse mortality rates in the early- and late-failure patients, respectively, were not significantly different at 7% and 3% at 1 year, and at 10% and 8% at 5 years. The corresponding progression/relapse rates were 41% and 35% at 1 year and 48% and 57% at 5 years; these were also not significantly different.

The adjusted progression-free survival (PFS) and overall survival (OS) in the groups at 5 years also did not differ significantly (PFS of 41% in both the early- and late-failure groups, and OS of 51% and 63%, respectively).

These outcomes are comparable to those seen with CAR T-cell therapy in refractory DLBCL patients in trials of CAR T-cell products, including the ZUMA-1 study of axicabtagene cyloleucel (Yescarta), which, in a 2019 update, showed survival plateaus of about 40% vs. the 5%-10% expected rate based on pre-CAR-T outcomes data; the JULIET trial of tisagenlecleucel (Kymriah), which showed survival plateaus in the range of 30%-35%; and the recently published TRANSCEND study of the investigational modified CAR-T product, lisocabtagene maraleucel, which also showed survival plateaus “in the range of 40%.”

“So all three agents are showing that CAR T cells represent a new treatment for diffuse large B-cell lymphoma in the relapsed/refractory setting,” Dr. Zelenetz said. “And as a result, [CAR T-cell therapy has] been included in the NCCN guidelines for transformed follicular lymphoma, for transformed marginal zone lymphoma, and for diffuse large B-cell lymphoma, as well as for refractory large B-cell lymphoma.

“But are CAR T cells absolutely required? Generally what we consider these days is that if you’re not in a PET-negative CR prior to high-dose therapy stem cell rescue, you should go on to CAR T cells,” Dr. Zelenetz said.

The analysis based on the CIBMTR registry data, however, suggests there may be other alternatives.

“The bottom line is that nonrelapse mortality was very low. Progression occurred in about half of the patients, but if we look at the overall and progression-free survival curves, there’s a plateau at around 45%,” Dr. Zelenetz said, explaining that the results are “very similar to the results that we’re getting in third-line treatment with CAR T cells, and this is a very similar population [of] PET-positive patients after second-line chemotherapy.”

CAR T-cell therapy can provide a durable CR in a portion of chemorefractory patients, and although there is room for improvement, “this represents a major step forward for these patients,” he said.

However, it’s not clear that CAR T cells are clearly superior to high-dose therapy and stem cell rescue for chemosensitive patients, he added, noting that “additional randomized trials are needed to answer this question, and they are ongoing as we speak.”

Dr. Zelenetz reported clinical research support or data safety monitoring board activity for BeiGene, Genentech, Juno Therapeutics, and MEI Pharma, and scientific advisory board, consulting, or expert witness activity for Celgene Corporation, Curries, Genentech, Gilead Sciences, Janssen Pharmaceutical Products, and several other pharmaceutical and biotechnology companies.

Is it time to consider chimeric antigen receptor (CAR) T-cell therapy for all relapsed/refractory diffuse large B-cell lymphoma patients? Maybe not, according to Andrew Zelenetz, MD, PhD.

CAR T-cell therapy has demonstrated activity in relapsed/refractory non-Hodgkin lymphoma (NHL), including diffuse large B-cell lymphoma (DLBCL), transformed indolent NHL, and mantle cell lymphoma, and can provide durable complete responses in a portion of patients with chemorefractory disease, Dr. Zelenetz, chair of the National Comprehensive Cancer Network Lymphoma Guidelines Panel and a specialist in lymphoma at Memorial Sloan Kettering Cancer Center in New York, said at the NCCN Hematologic Malignancies Annual Congress.

In chemosensitive patients, however, its role requires further examination, especially given findings from a recent analysis of patients from the Center for International Blood & Marrow Transplant Research (CIBMTR) registry showing comparable outcomes with high-dose chemotherapy and autologous stem cell rescue for patients with a positron emission testing–positive partial response (PR) after second-line chemotherapy, he said.

Of 249 patients who underwent a first autologous transplant for DLBCL between 2003 and 2018, received front-line rituximab chemotherapy, and had PET– or computed tomography–positive disease prior to transplant, 182 had early chemotherapy failure (within 12 months) and 67 had late chemotherapy failure (at 12 months or later) after therapy, according to findings from the study as reported at ASCO 2020.

Antibody response to the SARS-CoV-2 virus wanes over time, latest research has suggested.

An ongoing study led by Imperial College London (ICL) found that the proportion of people testing positive for COVID-19 antibodies dropped by 26.5% over a 3-month period between June and September.

The findings from a non–peer reviewed preprint suggested that infection with SARS-CoV-2 confers only limited protection against reinfection.

Professor Paul Elliott, director of the REACT-2 programme at ICL, said: “Testing positive for antibodies does not mean you are immune to COVID-19.

“It remains unclear what level of immunity antibodies provide, or for how long this immunity lasts.”

Experts said that, while the findings suggested that immunity might fade over time, the severity of illness from further infections could be reduced.
 

Antibody prevalence declined in all adults

Results from cross-sectional studies over the 3-month period involved 365,104 adults who self-administered a lateral flow immunoassay test.

There were 17,576 positive tests over the three rounds.

Antibody prevalence, adjusted for test characteristics and weighted to the adult population of England, declined from 6.0% to 4.4%, a reduction of 26.5% over the 3 months.

The decline was seen in all age groups. However, the lowest prevalence of a positive test, and the largest fall, was seen in those aged 75 years and older.

No change was seen in positive antibody tests in health care workers over the 3 months.

The results suggested that people who did not show symptoms of COVID-19 were more likely to lose detectable antibodies sooner than those who did show symptoms.

Prof Helen Ward, one of the lead authors of the report said that, while it was clear that the proportion of people with antibodies was falling over time, “We don’t yet know whether this will leave these people at risk of reinfection with the virus that causes COVID-19, but it is essential that everyone continues to follow guidance to reduce the risk to themselves and others.”
 

Results ‘weaken argument for herd immunity’

Commenting on the results to the Science Media Centre, Rowland Kao, professor of veterinary epidemiology and data science at the University of Edinburgh, warned that, if the results were correct, “any strategy that relies on ‘herd immunity’ lacks credibility.”

However, he added that, “while the decline is substantial, nevertheless substantial proportions of the population do retain some immune response, over 4 months after the peak of the epidemic”.

Eleanor Riley, professor of immunology and infectious disease, also from the University of Edinburgh, said it was too early to assume that immunity to SARS-CoV-2 did not last because “the study does not look at antibody concentrations, antibody function, or other aspects of immunity such as T-cell immunity and does not look at the trajectory of antibody levels in the same individuals over time”.

However, she said the findings did not mean that a vaccine would be ineffective because vaccines contained adjuvants that could induce durable immune responses, particularly with multiple immunizations.

“What is not clear is how quickly antibody levels would rise again if a person encounters the SARS-CoV-2 virus a second time. It is possible they will still rapidly respond, and either have a milder illness, or remain protected through immune memory,” commented Dr. Alexander Edwards, associate professor in biomedical technology at the University of Reading.

Health Minister Lord Bethell said: “Regardless of the result of an antibody test, everyone must continue to comply with government guidelines including social distancing, self-isolating, and getting a test if you have symptoms, and always remember: hands, face, space.”

A national effort to perform genotype drug matching across cancer types shows the value of next-generation sequencing and provides a roadmap for future precision oncology trials, according to experts.

Massachusetts General Hospital

The effort is the National Cancer Institute Molecular Analysis for Therapy Choice (NCI-MATCH) trial. For this study, researchers performed next-generation sequencing on tumor biopsy specimens to identify therapeutically actionable molecular alterations in patients with “underexplored” cancer types.

The trial included 5,954 patients with cancers that had progressed on standard treatments or rare cancers for which there is no standard treatment. If actionable alterations were found in these patients, they could receive new drugs in development that showed promise in other clinical trials or drugs that were approved by the Food and Drug Administration to treat at least one cancer type.

Data newly reported in the Journal of Clinical Oncology showed that 37.6% of patients had alterations that could be matched to targeted drugs, and 17.8% of patients were assigned to targeted treatment. Multiple actionable tumor mutations were seen in 11.9% of specimens, and resistance-conferring mutations were seen in 71.3% of specimens.

“The bottom line from this report is that next-generation sequencing is an efficient way to identify both approved and promising investigational therapies. For this reason, it should be considered standard of care for patients with advanced cancers,” said study chair Keith T. Flaherty, MD, director of the Henri and Belinda Termeer Center for Targeted Therapy at Massachusetts General Hospital Cancer Center in Boston.

“This study sets the benchmark for the ‘actionability’ of next-generation sequencing,” Dr. Flaherty added. “We expect this number [of actionable alterations] will continue to rise steadily as further advances are made in the development of therapies that target some of the genetic alterations for which we could not offer treatment options in NCI-MATCH.”
 

Relapsed/refractory vs. primary tumors

The NCI-MATCH researchers focused on the most commonly found genetic alterations and performed biopsies at study entry to provide the most accurate picture of the genetic landscape of relapsed/refractory cancer patients. That makes this cohort distinct from The Cancer Genome Atlas (TCGA), a database of patients with mostly untreated primary tumors, and other published cohorts that include genetic analysis of primary tumors and biopsies from the time of initial metastatic recurrence.

The researchers compared the tumor gene makeup of NCI-MATCH and TCGA patients with seven cancer types – breast, bile duct, cervix, colorectal, lung, pancreas, and prostate.

ECOG-ACRIN Cancer Research Group

“Perhaps the biggest surprise was the relatively minimal change in the genetic alterations found in these relapsed/refractory patients, compared to primary tumors,” Dr. Flaherty said. “These findings suggest that it is very reasonable to perform next-generation sequencing at the time of initial metastatic cancer diagnosis and to rely on those findings for the purposes of considering FDA-approved therapies and clinical trial participation.”
 

Multiple alterations and resistance

The complex genetics of cancers has led researchers to explore combinations of targeted and other therapies to address multiple defects at the same time.

“Not surprisingly, the most common collision of multiple genetic alterations within the same tumor was in the commonly altered tumor suppressor genes: TP53, APC, and PTEN,” Dr. Flaherty said.

“An increasing body of evidence supports a role for loss-of-function alterations in these genes to confer resistance to many targeted therapies,” he added. “While we don’t have targeted therapies yet established to directly counter this form of therapeutic resistance, we hypothesize that various types of combination therapy may be able to indirectly undercut resistance and enhance the benefit of many targeted therapies.”

The NCI-MATCH researchers will continue to mine this large dataset to better understand the many small, genetically defined cancer subpopulations.

“We will continue to report the outcome of the individual treatment subprotocols, and combining this genetic analysis with those outcomes will likely inform the next clinical trials,” Dr. Flaherty said.
 

Actionable mutations make a difference

Precision oncology experts agree that NCI-MATCH results are impressive and add a fuller appreciation that actionable mutations make a clinical difference.

“This is a powerful, extremely well-designed study, a tour de force of collaborative science,” said Stephen Gruber, MD, PhD, director of the Center for Precision Medicine at City of Hope National Medical Center in Duarte, Calif.

“The future holds even more promise,” he added. “Our ability to interrogate the genomic landscape of cancer is improving rapidly. Tumor testing helps get the right drug to the right tumor faster than a guidelines-based approach from historical data of combination chemotherapy. This is a likely game changer for the way oncologists will practice in the future, especially as we learn more results of subset trials. The NCI-MATCH researchers have taken a laser-focused look at the current data, but we now know we can look far more comprehensively at genomic profiles of tumors.”

From the viewpoint of the practicing oncologist, co-occurring resistance mutations make a difference in defining what combinations are likely and, more importantly, less likely to be effective. “When we see two mutations and one is likely to confer resistance, we can make a choice to avoid a drug that is not likely to work,” Dr. Gruber said.

“The NCI-MATCH trial allows both approved and investigational agents, which expands the possibility of matching patients to newer agents. This is especially relevant if there are no FDA-approved drugs yet for some molecular aberrations,” said Lillian L. Siu, MD, a senior medical oncologist at the Princess Margaret Cancer Centre in Toronto. “This trial enables such evaluations under the auspice of a clinical trial to provide important knowledge.”

Both experts agree that in-depth biological interrogations of cancer will move the field of precision oncology forward. Dr. Gruber said that “studies have not yet fully addressed the power of germline genetic testing of DNA. Inherited susceptibility will drive therapeutic choices – for example, PARP inhibitors that access homologous recombination deficiency for breast, ovarian, and prostate cancer. We will learn more about treatment choices for those cancers.”

Dr. Siu added: “I truly believe that liquid biopsies [circulating tumor DNA] will help us perform target-drug matching in a less invasive way. We need to explore beyond the genome to look at the transcriptome, proteome, epigenome, and immunome, among others. It is likely that multiomic predictors are going to be able to identify more therapeutic options compared to single genomic predictors.”

Dr. Flaherty noted that all tumor samples from patients assigned to treatment are being subjected to whole-exome sequencing to further the discovery of the genetic features of responsive and nonresponsive tumors.

NCI-MATCH was funded by the National Cancer Institute. Dr. Flaherty disclosed relationships with Clovis Oncology, Loxo, X4 Pharma, and many other companies. His coauthors disclosed many conflicts as well. Dr. Gruber is cofounder of Brogent International. Dr. Siu disclosed relationships with Agios, Treadwell Therapeutics, Merck, Pfizer, and many other companies.

“This is a powerful, extremely well-designed study, a tour de force of collaborative science,” said Stephen Gruber, MD, PhD, director of the Center for Precision Medicine at City of Hope National Medical Center in Duarte, Calif.

“The future holds even more promise,” he added. “Our ability to interrogate the genomic landscape of cancer is improving rapidly. Tumor testing helps get the right drug to the right tumor faster than a guidelines-based approach from historical data of combination chemotherapy. This is a likely game changer for the way oncologists will practice in the future, especially as we learn more results of subset trials. The NCI-MATCH researchers have taken a laser-focused look at the current data, but we now know we can look far more comprehensively at genomic profiles of tumors.”

From the viewpoint of the practicing oncologist, co-occurring resistance mutations make a difference in defining what combinations are likely and, more importantly, less likely to be effective. “When we see two mutations and one is likely to confer resistance, we can make a choice to avoid a drug that is not likely to work,” Dr. Gruber said.

“The NCI-MATCH trial allows both approved and investigational agents, which expands the possibility of matching patients to newer agents. This is especially relevant if there are no FDA-approved drugs yet for some molecular aberrations,” said Lillian L. Siu, MD, a senior medical oncologist at the Princess Margaret Cancer Centre in Toronto. “This trial enables such evaluations under the auspice of a clinical trial to provide important knowledge.”

Both experts agree that in-depth biological interrogations of cancer will move the field of precision oncology forward. Dr. Gruber said that “studies have not yet fully addressed the power of germline genetic testing of DNA. Inherited susceptibility will drive therapeutic choices – for example, PARP inhibitors that access homologous recombination deficiency for breast, ovarian, and prostate cancer. We will learn more about treatment choices for those cancers.”

Dr. Siu added: “I truly believe that liquid biopsies [circulating tumor DNA] will help us perform target-drug matching in a less invasive way. We need to explore beyond the genome to look at the transcriptome, proteome, epigenome, and immunome, among others. It is likely that multiomic predictors are going to be able to identify more therapeutic options compared to single genomic predictors.”

Dr. Flaherty noted that all tumor samples from patients assigned to treatment are being subjected to whole-exome sequencing to further the discovery of the genetic features of responsive and nonresponsive tumors.

A national effort to perform genotype drug matching across cancer types shows the value of next-generation sequencing and provides a roadmap for future precision oncology trials, according to experts.

Massachusetts General Hospital

The effort is the National Cancer Institute Molecular Analysis for Therapy Choice (NCI-MATCH) trial. For this study, researchers performed next-generation sequencing on tumor biopsy specimens to identify therapeutically actionable molecular alterations in patients with “underexplored” cancer types.

The trial included 5,954 patients with cancers that had progressed on standard treatments or rare cancers for which there is no standard treatment. If actionable alterations were found in these patients, they could receive new drugs in development that showed promise in other clinical trials or drugs that were approved by the Food and Drug Administration to treat at least one cancer type.

Data newly reported in the Journal of Clinical Oncology showed that 37.6% of patients had alterations that could be matched to targeted drugs, and 17.8% of patients were assigned to targeted treatment. Multiple actionable tumor mutations were seen in 11.9% of specimens, and resistance-conferring mutations were seen in 71.3% of specimens.

“The bottom line from this report is that next-generation sequencing is an efficient way to identify both approved and promising investigational therapies. For this reason, it should be considered standard of care for patients with advanced cancers,” said study chair Keith T. Flaherty, MD, director of the Henri and Belinda Termeer Center for Targeted Therapy at Massachusetts General Hospital Cancer Center in Boston.

“This study sets the benchmark for the ‘actionability’ of next-generation sequencing,” Dr. Flaherty added. “We expect this number [of actionable alterations] will continue to rise steadily as further advances are made in the development of therapies that target some of the genetic alterations for which we could not offer treatment options in NCI-MATCH.”
 

Relapsed/refractory vs. primary tumors

The NCI-MATCH researchers focused on the most commonly found genetic alterations and performed biopsies at study entry to provide the most accurate picture of the genetic landscape of relapsed/refractory cancer patients. That makes this cohort distinct from The Cancer Genome Atlas (TCGA), a database of patients with mostly untreated primary tumors, and other published cohorts that include genetic analysis of primary tumors and biopsies from the time of initial metastatic recurrence.

The researchers compared the tumor gene makeup of NCI-MATCH and TCGA patients with seven cancer types – breast, bile duct, cervix, colorectal, lung, pancreas, and prostate.

“Perhaps the biggest surprise was the relatively minimal change in the genetic alterations found in these relapsed/refractory patients, compared to primary tumors,” Dr. Flaherty said. “These findings suggest that it is very reasonable to perform next-generation sequencing at the time of initial metastatic cancer diagnosis and to rely on those findings for the purposes of considering FDA-approved therapies and clinical trial participation.”
 

Multiple alterations and resistance

The complex genetics of cancers has led researchers to explore combinations of targeted and other therapies to address multiple defects at the same time.

“Not surprisingly, the most common collision of multiple genetic alterations within the same tumor was in the commonly altered tumor suppressor genes: TP53, APC, and PTEN,” Dr. Flaherty said.

“An increasing body of evidence supports a role for loss-of-function alterations in these genes to confer resistance to many targeted therapies,” he added. “While we don’t have targeted therapies yet established to directly counter this form of therapeutic resistance, we hypothesize that various types of combination therapy may be able to indirectly undercut resistance and enhance the benefit of many targeted therapies.”

The NCI-MATCH researchers will continue to mine this large dataset to better understand the many small, genetically defined cancer subpopulations.

“We will continue to report the outcome of the individual treatment subprotocols, and combining this genetic analysis with those outcomes will likely inform the next clinical trials,” Dr. Flaherty said.

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.

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

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

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

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

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

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

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

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

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

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

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

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