San Diego – State-of-the-art guidelines for treating sickle cell disease are actively being developed and could be released as early as the spring of 2019, according to Robert Liem, MD, chair of the American Society of Hematology coordination panel for the initiative.

The new clinical practice recommendations will expand on 2014 guidelines published by the National Heart, Lung, and Blood Institute in a way that will help both hematologists and nonhematologists who take care of patients with sickle cell disease, Dr. Liem said in a video interview at the annual meeting of the American Society of Hematology.

Five different guidelines are under development to cover different aspects of acute and chronic complications of sickle cell disease, including pain, cardiopulmonary and kidney disease, cerebrovascular disease, transfusion support, and stem cell transplantation.

SAN DIEGO – A newly developed personalized model that “harnesses the power of artificial intelligence” to predict overall survival and transformation to acute myeloid leukemia (AML) in patients with myelodysplastic syndromes outperforms both the original and revised International Prognostic Scoring Systems (IPSS, IPSS-R), according to Aziz Nazha, MD.

The machine learning model, which was built using clinical and genomic data derived from myelodysplastic syndrome (MDS) patients diagnosed according to 2008 World Health Organization criteria, incorporates information beyond that included in the IPSS and IPSS-R, and provides patient-specific survival probabilities at different time points, Dr. Nazha of Cleveland Clinic reported during a press briefing at the annual meeting of the American Society of Hematology.

The model was developed in a combined training cohort of 1,471 patients from the Cleveland Clinic and Munich Leukemia Laboratory and was validated in a separate cohort of 831 patients from the Moffitt Cancer Center in Tampa, Fla.

The concordance index – a measure for comparing the accuracy of the various models – was 0.80 for overall survival (OS), and 0.78 for AML transformation vs. 0.66 and 0.73, respectively, for IPSS, and 0.67 and 0.73, respectively, for IPSS-R, Dr. Nazha said. The new “geno-clinical” model also outperformed mutations-only analysis, mutations plus cytogenetics analysis, and mutations plus cytogenetics plus age analyses for both OS and AML transformation.

Adding mutational variant allelic frequency did not significantly improve prediction accuracy, he noted.

Dr. Nazha and his colleagues are developing a web application tool that can be used to run the trained model to calculate patient-specific, time-specific OS and AML transformation probabilities. He discussed the new model and its implications for personalized prognosis and treatment in this video interview.

Improved risk assessment helps patients understand their disease and “establish expectations about their journey with their disease,” and it is also extremely important for treating physicians, he said.

“All of our consensus guidelines and treatment recommendations are based on risk,” he explained, noting that the approach varies greatly for higher- and lower-risk patients.

This model represents a potential new focus on “personalized prediction” in addition to the increasing focus on personalized treatment and takes into account the heterogeneous outcomes seen in patients with MDS, he said.

SAN DIEGO – Two-thirds of adults with relapsed or refractory diffuse large B-cell lymphoma who had early responses to chimeric antigen receptor T-cell (CAR T) therapy with tisagenlecleucel (Kymriah) remain in remission with no evidence of minimal residual disease, according to an updated analysis of the JULIET trial.

In the single-arm, open-label trial, the overall response rate after 19 months of follow-up was 54%, including 40% complete remissions and 14% partial remissions. The median duration of response had not been reached at the time of data cutoff, and the median overall survival had not been reached for patients with a complete remission. Overall survival in this heavily pretreated population as a whole (all patients who received CAR T-cell infusions) was 11.1 months.

Adverse events were similar to those previously reported and were manageable, according to investigator Richard Thomas Maziarz, MD, from the Oregon Health & Science Knight Cancer Institute in Portland.

In this video interview at the annual meeting of the American Society of Hematology, Dr. Maziarz discusses the promising results using CAR T cells in this difficult to treat population.

SAN DIEGO – Investigators demonstrated the feasibility of delivering genomic results in 7 days in a population of older, newly diagnosed patients with acute myeloid leukemia (AML).

The Beat AML Master Trial is an ongoing umbrella study that harnesses cytogenetic information and next generation sequencing to match patients with targeted therapies across a number of substudies or outside of the trial’s multicenter network.

The researchers chose AML for this precision-medicine study because of its rapid onset and lethal nature, its heterogeneity, and the availability of more-targeted therapies, said Amy Burd, PhD, of the Leukemia & Lymphoma Society, which is sponsoring the study.

Initial data from the trial showed that more than 95% of patients were assigned to treatment in 7 days or less, based on their personalized genomic information.

Overall, 285 patients had usable genomic screening data and were assigned to treatment. Of those patients, 273 were assigned to a treatment within 7 days, Dr. Burd reported at the annual meeting of the American Society of Hematology.

The speed of delivering these results is critical, said Joseph Mikhael, MD, chief medical officer for the International Myeloma Foundation in Phoenix, who moderated a media briefing on personalized medicine.

“One of the greatest challenges we faced in the concept of personalized medicine is by the time you’ve determined what is best for that patient ... the horse is already out of the barn,” Dr. Mikhael said. “You have to have started the patient on treatment already or else their disease could have progressed quite rapidly.”

In the past, genomic results might come back a month after the patient started therapy. “It was really almost academic,” he said.

In the Beat AML study, more than half (146 patients) were treated based on their AML subtype. The remaining patients (139) were not treated: 2.5% of patients died within 7 days, 7% of patients chose an alternative treatment prior to assignment, 20% chose standard of care, 9.1% chose an alternative trial after assignment, 8.1% chose palliative care, and the remainder had a reason that was not specified.

“The treatment decisions are made for what’s best for the patient even if that means a study outside of Beat AML,” Dr. Burd said.

Currently, there are 11 substudies offering treatment to trial participants across 13 clinical sites. There has been promising efficacy in many of the treatment arms, Dr. Burd said.

In the future, the researchers are looking to expand the substudies to look into novel drug combinations for certain AML subtypes, specifically isocitrate dehydrogenase 2–mutated groups.

Dr. Burd is an employee of the Leukemia & Lymphoma Society. Other coinvestigators reported financial relationships with the pharmaceutical industry. Dr. Mikhael reported research funding from AbbVie, Celgene, Onyx Pharmaceuticals, and Sanofi.

SAN DIEGO – Diversity of the gut microbiome, sampled either before or after an allogeneic hematopoietic cell transplant (HCT), is predictive of overall survival.

A multinational study of intestinal microbiota in the United States, Europe, and Japan showed that in all four geographic regions patients scheduled for HCT had about a 100% lower median diversity of intestinal bacteria, compared with healthy volunteers, and that enterococcal species predominated in the transplant candidates, reported Jonathan U. Peled, MD, PhD, from the bone marrow transplantation service at Memorial Sloan Kettering Cancer Center in New York.

The investigators also found that intestinal microbial diversity was significantly associated with overall survival following an HCT.

In a video interview at the annual meeting of the American Society of Hematology, Dr. Peled elaborated on the study findings and described potential pre- and posttransplant interventions that could improve results and increase survival following HCT.

Dr. Peled reported current or prior relationships with Seres Therapeutics, the Parker Institute for Cancer Immunotherapy, and Merck/Society for Immunotherapy of Cancer.

CHICAGO – Apixaban outperformed two other direct-acting oral anticoagulants, dabigatran and rivaroxaban, by preventing more thrombotic events and not causing as many major bleeds in patients with atrial fibrillation who were at least 80 years old.

The findings come from an analysis of insurance claims data from more than 50,000 U.S. patients – the largest observational study to date to compare these three direct-acting oral anticoagulants (DOACs) in octogenarians with nonvalvular atrial fibrillation, Steven B. Deitelzweig, MD, said at the American Heart Association scientific sessions.

“The results may help clinicians evaluate the risk-benefit ratio of the DOACs” in this population, said Dr. Deitelzweig, vice president for medical affairs at Ochsner Medical Center in New Orleans.

He noted that the results were consistent with prior reports from observational data and registries, as well as the results in a recent analysis commissioned by the Agency for Healthcare Research and Quality. “We see a consistent message that apixaban always has less risk for major bleeding, and at least comparable efficacy” when compared with other DOACs, he said in a video interview.

And for the foreseeable future, this sort of data will need to suffice for clinicians trying to decide which DOAC to use because “I know of no head-to-head trials, nor do I anticipate any head-to-head trials” that could provide a more definitive comparison of the DOACs, Dr. Deitelzweig said.

The data came from a large number of patients – about 38% of the U.S. population – which boosts the generalizability of the finding. “I think our data are useful” for helping to make treatment decisions, he concluded.

The analysis he reported came from the ARISTOPHANES (Anticoagulants for Reduction in Stroke: Observational Pooled Analysis on Health Outcomes and Experience of Patients) study, which pooled U.S. insurance claims data from several sources. For the octogenarian study, Dr. Deitelzweig and his associates used data from about 123 million U.S. residents collected between January 2012 and September 2015 by Medicare and three different commercial insurance databases. The overall level of beneficiary overlap between these four data sources was less than 0.5%.

The researchers identified patients with nonvalvular atrial fibrillation who started anticoagulant treatment with a DOAC and were at least 80 years old. This included 19,752 patients started on apixaban (Eliquis), 6,741 started on dabigatran (Pradaxa), and 27,217 started on rivaroxaban (Xarelto). A majority of the patients were at least 84 years old.

The analysis used propensity-score matching to compare similar patients and to minimize the impact of potentially confounding differences among the patients in each treatment subgroup. During a median follow-up of 7-9 months, the incidence of stroke or systemic embolism was 35% lower in the apixaban-treated patients, compared with those who received dabigatran, and 28% lower in the apixaban patients, compared with those treated with rivaroxaban, both statistically significant differences, Dr. Deitelzweig reported. The incidence of major bleeding episodes was 40% lower with apixaban than with dabigatran and 50% lower with apixaban, compared with rivaroxaban, also statistically significant differences.

When the analysis compared dabigatran with rivaroxaban it showed no statistically significant difference for the efficacy endpoint, but dabigatran produced 23% fewer major bleeds than rivaroxaban, a statistically significant difference.

These findings jibed with a recently published analysis from Dr. Deitelzweig and his associates that used data from all adults with nonvalvular atrial fibrillation started on an oral anticoagulant in an expanded ARISTOPHANES database for 2012-2015 that included more than 180 million U.S. beneficiaries. After propensity-score matching, this created subgroups of about 58,000 patients started on apixaban, nearly 27,000 started on dabigatran, and more than 83,000 started on rivaroxaban. The patients averaged about 73 years old. Again, with about 7-9 months of follow-up, very similar outcomes occurred. Patients on apixaban had significantly fewer strokes and systemic embolic events as well as significantly fewer major bleeds compared with patients treated with one of the other DOACs (Stroke. 2018 Dec;49[12]:2933-44).

The study was funded by Bristol-Myers Squibb and Pfizer, the companies that market apixaban (Eliquis). Dr. Deitelzweig is a consultant to and speaker on behalf of Bristol-Myers Squibb and Pfizer.

CHICAGO – Apixaban outperformed two other direct-acting oral anticoagulants, dabigatran and rivaroxaban, by preventing more thrombotic events and not causing as many major bleeds in patients with atrial fibrillation who were at least 80 years old.

The findings come from an analysis of insurance claims data from more than 50,000 U.S. patients – the largest observational study to date to compare these three direct-acting oral anticoagulants (DOACs) in octogenarians with nonvalvular atrial fibrillation, Steven B. Deitelzweig, MD, said at the American Heart Association scientific sessions.

“The results may help clinicians evaluate the risk-benefit ratio of the DOACs” in this population, said Dr. Deitelzweig, vice president for medical affairs at Ochsner Medical Center in New Orleans.

He noted that the results were consistent with prior reports from observational data and registries, as well as the results in a recent analysis commissioned by the Agency for Healthcare Research and Quality. “We see a consistent message that apixaban always has less risk for major bleeding, and at least comparable efficacy” when compared with other DOACs, he said in a video interview.

And for the foreseeable future, this sort of data will need to suffice for clinicians trying to decide which DOAC to use because “I know of no head-to-head trials, nor do I anticipate any head-to-head trials” that could provide a more definitive comparison of the DOACs, Dr. Deitelzweig said.

The data came from a large number of patients – about 38% of the U.S. population – which boosts the generalizability of the finding. “I think our data are useful” for helping to make treatment decisions, he concluded.

The analysis he reported came from the ARISTOPHANES (Anticoagulants for Reduction in Stroke: Observational Pooled Analysis on Health Outcomes and Experience of Patients) study, which pooled U.S. insurance claims data from several sources. For the octogenarian study, Dr. Deitelzweig and his associates used data from about 123 million U.S. residents collected between January 2012 and September 2015 by Medicare and three different commercial insurance databases. The overall level of beneficiary overlap between these four data sources was less than 0.5%.

The researchers identified patients with nonvalvular atrial fibrillation who started anticoagulant treatment with a DOAC and were at least 80 years old. This included 19,752 patients started on apixaban (Eliquis), 6,741 started on dabigatran (Pradaxa), and 27,217 started on rivaroxaban (Xarelto). A majority of the patients were at least 84 years old.

The analysis used propensity-score matching to compare similar patients and to minimize the impact of potentially confounding differences among the patients in each treatment subgroup. During a median follow-up of 7-9 months, the incidence of stroke or systemic embolism was 35% lower in the apixaban-treated patients, compared with those who received dabigatran, and 28% lower in the apixaban patients, compared with those treated with rivaroxaban, both statistically significant differences, Dr. Deitelzweig reported. The incidence of major bleeding episodes was 40% lower with apixaban than with dabigatran and 50% lower with apixaban, compared with rivaroxaban, also statistically significant differences.

When the analysis compared dabigatran with rivaroxaban it showed no statistically significant difference for the efficacy endpoint, but dabigatran produced 23% fewer major bleeds than rivaroxaban, a statistically significant difference.

These findings jibed with a recently published analysis from Dr. Deitelzweig and his associates that used data from all adults with nonvalvular atrial fibrillation started on an oral anticoagulant in an expanded ARISTOPHANES database for 2012-2015 that included more than 180 million U.S. beneficiaries. After propensity-score matching, this created subgroups of about 58,000 patients started on apixaban, nearly 27,000 started on dabigatran, and more than 83,000 started on rivaroxaban. The patients averaged about 73 years old. Again, with about 7-9 months of follow-up, very similar outcomes occurred. Patients on apixaban had significantly fewer strokes and systemic embolic events as well as significantly fewer major bleeds compared with patients treated with one of the other DOACs (Stroke. 2018 Dec;49[12]:2933-44).

The study was funded by Bristol-Myers Squibb and Pfizer, the companies that market apixaban (Eliquis). Dr. Deitelzweig is a consultant to and speaker on behalf of Bristol-Myers Squibb and Pfizer. He is also a consultant to or speaker on behalf of Boehringer Ingelheim, Daiichi-Sankyo, Janssen, and Portola Pharmaceuticals.

SAN DIEGO – A hematopoietic cell transplant following chimeric antigen receptor (CAR) T-cell therapy for B-cell acute lymphocytic leukemia (B-ALL) may reduce late relapse risk in certain patients, a retrospective analysis suggests.

Corinne Summers, MD, of Seattle Children’s Hospital, and her colleagues evaluated the potential benefits of allogeneic hematopoietic cell transplant (HCT) in 50 pediatric and young adult B-ALL patients who had sustained leukemic remission after receiving SCRI-CAR19v1, a CD19-specific CAR T-cell product.

Leukemia-free survival was significantly improved for patients with no history of HCT who received CD19 CAR T-cell therapy followed by consolidative HCT, Dr. Summers reported at the annual meeting of the American Society of Hematology.

However, the benefits of consolidative HCT are unclear for patients with a history of HCT, Dr. Summers said at the meeting, noting that larger studies are needed.

In her video interview at ASH 2018, Dr. Summers talked more about the challenges of late leukemic relapse and the potential role of HCT after CAR T-cell therapy.

Dr. Summers reported no disclosures related to her presentation.

SAN DIEGO – A novel myeloablative regimen along with familial haploidentical stem cell transplantation was well tolerated and cured 90% of 19 young patients with high-risk sickle cell disease who underwent the procedure, according to Mitchell S. Cairo, MD.

The approach involved parental donors who were partial matches (as opposed to human leukocyte antigen [HLA]–matched sibling donors), CD34 enrichment, and mononuclear cell add-back (2 x 10⁵ CD3/kg). The treatment resulted in a low cumulative incidence of acute and chronic graft-versus-host disease (6.2% and 6.7%, respectively) and stable to improved pulmonary and cardiac function. Patients also experienced significantly improved neurocognition and health-related quality of life at 2-year follow-up, Dr. Cairo of New York Medical College, Valhalla, reported at the annual meeting of the American Society of Hematology.

In a video interview, Dr. Cairo described the study, the potential benefits of familial haploidentical transplantation, and future directions.

“We have a 1-year 90% survival rate, and ... with a median follow-up now of 3 years with this approach, no patient has signs or symptoms of sickle cell disease,” he said. While the standard of care is “still to use an HLA-matched sibling donor that doesn’t have sickle cell disease,” this novel approach could benefit the five of six patients who don’t have such a donor.

The risks appear similar with the two approaches, but “more numbers will be needed to confirm this preliminary finding,” he said.

A second Food and Drug Administration–supported study with patients aged up to age 35 years (vs. 21 years in the current study) and with lower doses of the conditioning regimen to potentially reduce the risk of late adverse effects is underway, he said.

This study was supported by an FDA grant. Dr. Cairo reported receiving research funding from Janssen.

SAN DIEGO – Sickle cell research is booming after decades of stagnation, and talk of a cure is real, according to sickle cell disease expert Ifeyinwa (Ify) Osunkwo, MD.

“There is an opportunity to cure your disease no matter what age you are,” Dr. Osunkwo, medical director of the sickle cell program at Levine Cancer Institute at Atrium Health in Charlotte, N.C., said in a video interview at the annual meeting of the American Society of Hematology. “Sickle cell disease is now a disease of all ages and the treatments have to be treatments for everybody of all ages, not just for children.”

Dr. Osunkwo was the moderator of a press conference highlighting top research in sickle cell disease at ASH 2018. She pointed to findings from first-in-human trials of gene therapy using a lentiviral vector targeting BCL11A to reverse the sickle cell phenotype, as well as a study examining familial haploidentical stem cell transplantation with CD34 enrichment and mononuclear add-back in high-risk patients.

These two studies show parallel progress in curative therapies and are complementary, Dr. Osunkwo said. Improvements in transplants, and specifically in how patients are prepared and managed for them, will have a benefit in gene therapy.

But there are many other sickle cell disease studies being presented at ASH this year, she noted.

“There’s a recognition that sickle cell has been an understudied, underresourced, underexposed population,” she said. “And the suffering and the magnitude of medical problems is huge and it finally has bubbled up to the surface.”

Dr. Osunkwo reported being on advisory committees for Novartis and Pfizer and on the speaker’s bureau for Novartis. She has received honoraria from Terumo BCT and funding from the Health Resources and Services Administration and the Patient-Centered Outcomes Research Institute.

SAN DIEGO – Patients aged younger than 60 years with favorable-prognosis diffuse large B-cell lymphoma who were randomly assigned to therapy with four cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) had progression-free, event-free, and overall survival rates comparable with those of patients assigned to six cycles, investigators in the FLYER trial reported.

The four-cycle regimen was associated with a marked reduction in adverse events, with an overall drop in nonhematologic malignancies of approximately one-third compared with the six-cycle regimen.

For younger patients with favorable-prognosis DLBCL – defined as an age-adjusted International Prognostic Index score of 0 and low tumor burden (less than 7.5 cm) – four cycles of R-CHOP can be a new standard of care.

In this video interview at the annual meeting of the American Society of Hematology, Viola Poeschel, MD, of Saarland University in Homburg, Germany, describes the patient population who may benefit from shorter duration therapy.
