Model bests IPSS-R for predicting survival, risk for AML in myelodysplastic syndrome
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.

TOURMALINE-MM3: Ixazomib improves PFS after myeloma transplant
SAN DIEGO – Ixazomib improved progression-free survival following autologous stem cell transplantation (ASCT) in patients with newly diagnosed multiple myeloma, according to results of a double-blind, randomized, placebo-controlled, phase 3 trial.
Treatment with the oral proteasome inhibitor for 24 months was well tolerated, had a low discontinuation rate, and improved progression-free survival by 39% versus placebo, according to Meletios A. Dimopoulos, MD, of the National and Kapodistrian University of Athens.
These findings suggest ixazomib (Ninlaro) represents a “new treatment option for maintenance after transplantation,” Dr. Dimopoulos said at the annual meeting of the American Society of Hematology.
The trial, known as TOURMALINE-MM3, is the first-ever randomized, double-blind, placebo-controlled study of a proteasome inhibitor used as maintenance after ASCT, according to Dr. Dimopoulos. Lenalidomide is approved in that setting, but 29% of patients who start the treatment discontinue because of treatment-related adverse events.
“Proteasome inhibitors have a different mechanism of action and may provide an alternative to lenalidomide,” Dr. Dimopoulos said at an oral abstract session. Ixazomib has a manageable toxicity profile and “convenient” weekly oral dosing, making it “well suited” for maintenance.
When asked by an attendee whether ixazomib would become “the standard of care” for younger patients with myeloma in this setting, Dr. Dimopoulos replied the results show that ixazomib “is an option for patients, especially for those where a physician may believe that a proteasome inhibitor may be indicated.”
However, when pressed by an attendee to comment on how ixazomib compares with lenalidomide for maintenance, Dr. Dimopoulos remarked that current maintenance studies are moving in the direction of combining therapies.
“I think that instead of saying, ‘is ixazomib better than lenalidomide?’ or vice versa, it is better to see how one may combine those drugs in subsets of patients, or even combine these drugs with other agents,” he said.
The TOURMALINE-MM3 study included 656 patients randomized posttransplantation to receive weekly ixazomib or placebo for up to 2 years.
The median progression-free survival was 26.5 months for ixazomib versus 21.3 months for placebo (P = .002; hazard ratio, 0.720; 95% confidence interval, 0.582-0.890). Median overall survival had not been reached in either ixazomib or placebo arms as of this report, with a median follow-up of 31 months.
The discontinuation rate was 7% for ixazomib versus 5% for placebo, according to the investigator. Moreover, ixazomib was associated with “low toxicity” and no difference in the rates of new primary malignancies, at 3% in both arms.
A manuscript describing results of the TOURMALINE-MM3 study is in press in the Lancet, with an expected online publication date of Dec. 10, Dr. Dimopoulos told attendees. Other studies are ongoing to evaluate ixazomib combinations and treatment to progression in this setting.
TOURMALINE-MM3 is sponsored by Takeda (Millennium), the maker of ixazomib. Dr. Dimopoulos reported honoraria and consultancy with Janssen, Takeda Pharmaceutical, Amgen, Bristol-Myers Squibb, and Celgene.

JULIET: CAR T cells go the distance in r/r DLBCL
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.

Beat AML trial delivers genomic results in 7 days
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.

Gut bacteria influence HCT outcomes
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.

JULIET: CAR T cells keep trucking against DLBCL
SAN DIEGO – Chimeric antigen receptor T-cell therapy with tisagenlecleucel (Kymriah) is associated with a high rate of durable responses in adults with relapsed or refractory diffuse large B-cell lymphoma, an updated analysis of the JULIET trial showed.
After a median follow-up of 19 months, two-thirds of adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who had early responses to chimeric antigen receptor (CAR) T-cell therapy with tisagenlecleucel remained in remission with no evidence of minimal residual disease, reported Richard Thomas Maziarz, MD, from the Oregon Health & Science Knight Cancer Institute in Portland, at the annual meeting of the American Society of Hematology.
“Since the previous report, no new deaths have been reported due to any cause other than patient disease progression. No treatment-related mortality was seen throughout the study, and there were three early deaths, all related to lymphoma that progressed,” he said in a briefing prior to presentation of the data in a scientific poster.

In the phase 2, single-arm trial, investigators enrolled adults with DLBCL that had relapsed or was refractory after two or more prior lines of therapy and who were either ineligible for hematopoietic stem cell transplant or who experienced disease progression after transplant.
Interim results of the study were previously reported at the European Hematology Association Congress in 2017.
At that meeting, Gilles Salles, MD, PhD, from the University of Lyon (France), presented results of an analysis of available efficacy data on 51 patients with at least 3 months of follow-up. In this population, the best overall response rate was 59%. The 3-month overall response rate was 45%, consisting of 37% complete responses and 8% partial responses. Relapse-free survival at 6 months was 79% and all patients who had responses at 3 months continued to have responses at the time of data cutoff.

In the most recent analysis, completed after a median time from infusion to data cutoff of 14 months, the investigators reported on efficacy in 93 patients who received CAR T-cell infusions.
The best overall response rate, the primary endpoint, was 52%, comprising 40% complete responses and 12% partial responses. The response rates were consistent across all prognostic subgroups, including age, sex, previous response status, International Prognostic Index score at enrollment, prior therapy, molecular subtype, and other factors.
Estimated relapse-free survival 12 months after documentation of an initial response was 65%, and was 79% among patients who had complete responses.
The median duration of response had not been reached at the time of data cutoff; 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 of special interest included grade 3 or 4 cytokine release syndrome (CRS) in 23% of patients, prolonged cytopenia in 34%, infections in 19%, neurologic events in 11%, febrile neutropenia in 15%, and tumor lysis syndrome in 2%.
There were no deaths attributable to CRS or to cerebral edema, a complication of CAR T-cell therapy that appears to be related to the costimulatory molecule used in various constructs.
“Patients with relapsed or refractory DLBCL who are not eligible for high-dose therapy and hematopoietic cell transplantation or for whom such therapy was not successful have very few treatment options. For these patients, tisagenlecleucel shows promise that will need to be confirmed through larger studies with longer follow-up,” the investigators wrote in the New England Journal of Medicine.

SAN DIEGO – Chimeric antigen receptor T-cell therapy with tisagenlecleucel (Kymriah) is associated with a high rate of durable responses in adults with relapsed or refractory diffuse large B-cell lymphoma, an updated analysis of the JULIET trial showed.
After a median follow-up of 19 months, two-thirds of adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who had early responses to chimeric antigen receptor (CAR) T-cell therapy with tisagenlecleucel remained in remission with no evidence of minimal residual disease, reported Richard Thomas Maziarz, MD, from the Oregon Health & Science Knight Cancer Institute in Portland, at the annual meeting of the American Society of Hematology.
“Since the previous report, no new deaths have been reported due to any cause other than patient disease progression. No treatment-related mortality was seen throughout the study, and there were three early deaths, all related to lymphoma that progressed,” he said in a briefing prior to presentation of the data in a scientific poster.

ELIANA update: Tisagenlecleucel responses durable in r/r B-cell ALL
SAN DIEGO – A single infusion of tisagenlecleucel (Kymriah) continues to demonstrate high efficacy a year and a half after pediatric and young adult patients with relapsed or refractory acute lymphoblastic leukemia (ALL) were enrolled in the pivotal ELIANA trial, Stephan A. Grupp, MD, PhD, reported at a press conference at the annual meeting of the American Society of Hematology.
Of patients in complete remission after receiving the chimeric antigen receptor (CAR) T-cell therapy, 66% were still in remission at 18 months of follow-up and median survival has yet to be reached.
“We think the efficacy is sustained and excellent,” said Dr. Grupp, of the University of Pennsylvania, Philadelphia. “These are durable complete responses even without further therapy. We haven’t reached median duration of response or overall survival, and we can manage toxicity, so I think this is clearly an opportunity for us to treat our patients both in America and across the world.”
The results of ELIANA were the basis for the approval of tisagenlecleucel (Kymriah) for relapsed/refractory B-cell ALL in the United States, and for subsequent approvals by health authorities in the European Union, Switzerland, and Canada.
The international, single-arm, open-label, phase 2 ELIANA trial included 97 patients aged 3-24 years with relapsed or refractory B-cell ALL, most of whom had previously undergone a hematopoietic stem cell transplant. Of those patients, 79 patients went on to receive a single infusion of the CAR T-cell therapy.
The rate of overall remission, defined as the rate of complete remission or complete remission with incomplete blood count recovery, was 82% (65 patients). Among those patients, 66% were still in remission at 18 months, while overall survival was “excellent” at 70%, Dr. Grupp said, and the median overall survival was not reached.
Adverse events prevalence remained relatively unchanged since the previous analyses, according to Dr. Grupp, who added that appropriately trained personnel were able to effectively manage those adverse events across study sites. Cytokine release syndrome (CRS) occurred in 77% of patients. All cases were reversible; 39% received tocilizumab for treatment of CRS with or without other anticytokine therapies; 48% required ICU-level care for CRS, with a median ICU stay of 7 days.
The other most common grade 3/4 nonhematologic adverse events were neutropenia with a body temperature exceeding 38.3° C (62% within 8 weeks of infusion), hypoxia (20%), and hypotension (20%). Grade 3 neurologic effects occurred in 13% of patients, and none had cerebral edema. Based on laboratory results, 43% had grade 3/4 thrombocytopenia and 54% had neutropenia not resolved by day 28; most of these events resolved to grade 2 or less by 3 months.
There were 25 postinfusion deaths, with 2 occurring within 30 days (1 because of disease progression, 1 because of cerebral hemorrhage). Of the 23 deaths after 30 days (range, 53-859 days), 18 were caused by disease progression. The other deaths were caused by encephalitis, systemic mycosis, vasoocclusive hepatobiliary disorder related to allogeneic SCT, bacterial lung infection, and an unknown reason after study withdrawal.
Follow-up is ongoing in the ELIANA study, which is supported by Novartis, the maker of Kymriah.
Dr. Grupp reported research funding from Novartis, consultancy with Novartis, Jazz Pharmaceuticals, and Adaptimmune Therapeutics, and patents or royalties with the University of Pennsylvania.

Ibrutinib outperforms bendamustine and rituximab in older CLL patients
SAN DIEGO – Ibrutinib alone or in combination with rituximab resulted in superior progression-free survival (PFS) when compared with bendamustine plus rituximab in the randomized, phase 3 Alliance A041202 trial of older patients with previously untreated chronic lymphocytic leukemia (CLL).
“There was no difference in progression-free survival between ibrutinib and ibrutinib plus rituximab,” said Dr. Woyach of the Ohio State University, Columbus.
Median PFS in this study was 43 months in the BR arm, and was not reached in either of the ibrutinib-containing arms, she said. No significant differences in overall survival (OS) were seen among the treatment arms, which may have been because of short follow-up and the fact that patients in the BR arm were allowed to cross over to ibrutinib if they progressed on treatment.
Participants in the international, multicenter trial – a project of the National Cancer Institute National Clinical Trials Network – were 547 adults aged 65 years or older (median, 71 years) with previously untreated, symptomatic CLL. They were enrolled from 219 sites across the United States and Canada between Dec. 9, 2013, and May 16, 2016.
The three arms were well matched with respect to baseline characteristics except for a slightly higher number of patients with complex karyotypes in the IR arm, Dr. Woyach said.
Treatment in the BR arm included bendamustine 90 mg/m2 on days 1 and 2 of each 28-day cycle plus rituximab at a dose of 375 mg/m2 on day 0 of cycle 1 then 500 mg/m2 on day 1 of cycles 2-6. Patients in the ibrutinib arms received 420 mg daily until disease progression either with or without rituximab at 375 mg/m2 weekly for 4 weeks starting at cycle 2 day 1 and then given on day 1 of cycles 3-6.
Grade 3-5 treatment-emergent hematologic adverse events (AEs) occurred in 61%, 41%, and 38% of patients in the BR, ibrutinib, and IR arms, respectively. Neutropenia and thrombocytopenia occurred more often in the BR than in the ibrutinib arms. Nonhematologic AEs occurred in 63%, 74%, and 74%, respectively, with an overall greater incidence in the ibrutinib arms. Infections and sudden deaths were numerically but not significantly higher in the ibrutinib arms.
“We undertook this study to determine the most effective therapy for older patients with CLL,” Dr. Woyach said, explaining that while older patients make up the majority of patients with CLL, they are typically underrepresented in trials.
At the start of the study, BR was widely used and the Bruton’s tyrosine kinase inhibitor ibrutinib was “just entering the clinic,” she noted.
“Despite now-widespread use in the [front-line setting] following FDA approval for this indication in 2016, the efficacy of ibrutinib versus standard chemoimmunotherapy has not previously been investigated,” she said.
Since adding rituximab has been shown to improve PFS and OS when added to chemotherapy in CLL, she and her colleagues also looked at whether this was the case with ibrutinib as well.
“This is the only phase 3 trial designed to answer this question,” she noted, adding that the findings justify the use of ibrutinib as a standard-of-care treatment for CLL patients aged 65 years and older.
David P. Steensma, MD, of Dana-Farber Cancer Institute in Boston, who moderated the press briefing, agreed. “I think this really does indicate that ibrutinib as front-line therapy, which many clinicians have been doing, is a very reasonable practice.”
Dr. Woyach added, however, that while ibrutinib represents a major therapeutic advance, its cost and its toxicities in older patients are a concern that warrant close monitoring and development of strategies to reduce the need for long-term continuous treatment.
Additional phase 3 studies set to open soon will compare ibrutinib in combination with venetoclax and obinutuzumab with standard ibrutinib

Treatment in the BR arm included bendamustine 90 mg/m2 on days 1 and 2 of each 28-day cycle plus rituximab at a dose of 375 mg/m2 on day 0 of cycle 1 then 500 mg/m2 on day 1 of cycles 2-6. Patients in the ibrutinib arms received 420 mg daily until disease progression either with or without rituximab at 375 mg/m2 weekly for 4 weeks starting at cycle 2 day 1 and then given on day 1 of cycles 3-6.
Grade 3-5 treatment-emergent hematologic adverse events (AEs) occurred in 61%, 41%, and 38% of patients in the BR, ibrutinib, and IR arms, respectively. Neutropenia and thrombocytopenia occurred more often in the BR than in the ibrutinib arms. Nonhematologic AEs occurred in 63%, 74%, and 74%, respectively, with an overall greater incidence in the ibrutinib arms. Infections and sudden deaths were numerically but not significantly higher in the ibrutinib arms.
“We undertook this study to determine the most effective therapy for older patients with CLL,” Dr. Woyach said, explaining that while older patients make up the majority of patients with CLL, they are typically underrepresented in trials.
At the start of the study, BR was widely used and the Bruton’s tyrosine kinase inhibitor ibrutinib was “just entering the clinic,” she noted.
“Despite now-widespread use in the [front-line setting] following FDA approval for this indication in 2016, the efficacy of ibrutinib versus standard chemoimmunotherapy has not previously been investigated,” she said.
Since adding rituximab has been shown to improve PFS and OS when added to chemotherapy in CLL, she and her colleagues also looked at whether this was the case with ibrutinib as well.
“This is the only phase 3 trial designed to answer this question,” she noted, adding that the findings justify the use of ibrutinib as a standard-of-care treatment for CLL patients aged 65 years and older.
David P. Steensma, MD, of Dana-Farber Cancer Institute in Boston, who moderated the press briefing, agreed. “I think this really does indicate that ibrutinib as front-line therapy, which many clinicians have been doing, is a very reasonable practice.”
Dr. Woyach added, however, that while ibrutinib represents a major therapeutic advance, its cost and its toxicities in older patients are a concern that warrant close monitoring and development of strategies to reduce the need for long-term continuous treatment.
Additional phase 3 studies set to open soon will compare ibrutinib in combination with venetoclax and obinutuzumab with standard ibrutinib

Opioids appear safe for sickle cell pain
SAN DIEGO – Inpatient deaths from opioid overdose in the U.S. population has risen dramatically in recent years, but this is essentially a “never event” among patients with sickle cell disease (SCD).
These findings come from an analysis of hospital discharge data in the National Inpatient Sample from 1998 to 2013. Oladimeji Akinola Akinboro, MBBS, who led the study, said the findings suggest that the current patterns of opioid use in SCD patients are safe and that opioids should not be withheld when they are appropriate.
From 1998 to 2013, the rate of inpatient deaths from opioid overdose in the United States rose 350% overall and approximately 8% annually. In contrast, deaths among SCD patients were flat, with a rate at or near zero throughout the same time period.
Over the 16-year period, there were just nine deaths reported among SCD patients because of opioids in the inpatient setting, Dr. Akinboro of Boston University Medical Center reported at the annual meeting of the American Society of Hematology.
While the reasons behind the difference were not explored in the study, Dr. Akinboro suggested that the sickle cell community has greater experience with opioids and that patients and physicians typically have long-standing clinical relationships that make mitigation of opioid misuse easier to manage.
Opioid-related hospitalizations, however, were comparable among the general U.S. population and SCD patients. And for both groups the rates remained relatively steady throughout the study period, with the exception of a drop among SCD patients in 2002, he noted.
The study also revealed age-related trends in hospitalizations overall. Hospitalizations among sickle cell patients were stable from 1998 to 2013. However, when the researchers broke the data down by age they found that adults aged 18-44 years had an increase in hospitalizations, with the steepest rise in patients aged 65 years and older.
In total, there were more than 1.7 million hospitalizations among SCD patients in the United States from 1998 to 2013. The rate declined by 9.9% each year from 1998 to 2002, then remained flat at around 27 per 100,000 persons from 2002 to 2013.
However, for adults aged 18-44 years, hospitalizations increased from 43 per 100,000 persons in 2002 to 71 per 100,000 persons in 2013 – an annual increase of 3.8%. Patients aged 65 years and older saw their rate of hospitalization increase from 2.7 to 5.4 per 100,000 persons from 1998 to 2013 – a 6.5% increase for each year.
The study did not explore the causes behind the age-related trends but Dr. Akinboro suggested it may be because of fragmentation of adult SCD care and age- and pain-related medical comorbidities.
The researchers reported having no relevant financial disclosures.

MEDALIST: Erythroid maturation agent reduced transfusion burden in MDS
SAN DIEGO – A novel erythroid maturation agent significantly reduced transfusion burden versus placebo in patients with anemia caused by myelodysplastic syndromes (MDS) and ringed sideroblasts, results of a randomized, phase 3 trial demonstrate.
Luspatercept was “very well tolerated” and responses were durable, with approximately 40% of patients remaining transfusion free after 1 year of therapy, said Alan F. List, MD, of Moffitt Cancer Center, Tampa.
“Luspatercept is a potential new therapy that we think could be very effective in patients with lower-risk MDS with ringed sideroblasts who are red blood cell transfusion–dependent,” said Dr. List, senior author of the MEDALIST trial, said in a press conference at the annual meeting of the American Society of Hematology.
The first-in-class erythroid maturation agent is being developed as a treatment for anemia related to MDS and beta-thalassemia, Dr. List said.
In a separate randomized, placebo-controlled, phase 3 study presented at ASH 2018, Maria Domenica Cappellini, MD, of the University of Milan, reported that, in beta-thalassemia patients who were transfusion dependent, luspatercept treatment resulted in a statistically significant reductions in transfusion burden versus placebo, and was generally well tolerated.
Luspatercept is a soluble receptor chimera that binds to an array of ligands in the transforming growth factor–beta superfamily, which is known to be important in suppressing erythropoiesis in patients with MDS, Dr. List said.
The MDS study included patients with very low–, low-, or intermediate-risk disease and ringed sideroblasts who were RBC transfusion–dependent and were refractory to, unresponsive to, or ineligible for first-line treatment with an erythropoiesis-stimulating agent (ESA).
A total of 153 patients were randomly allocated to luspatercept 1.0 mg/kg, administered subcutaneously every 21 days for at least 24 weeks, while 76 were randomized to placebo every 21 days. The primary end point was the proportion of patients achieving RBC transfusion independence for at least 8 weeks during the first 24 weeks of treatment.
A total of 37.9% of luspatercept-treated patients achieved that primary endpoint, compared with 13.2% of placebo-treated patient (P less than .0001), Dr. List reported. The luspatercept-treated patients also had a 52.9% rate of erythroid response, compared with 11.8% in the placebo group (P less than .0001).
There were no differences in treatment-emergent adverse events, severe adverse events, or frequency of progression of acute myeloid leukemia. “This was a very clean drug and a very safe drug,” he said.
The decision to study luspatercept in patients with ringed sideroblasts was based on results of a large, phase 2 European study showing a higher response rate in that subset of MDS patients, according to Dr. List.
That study also included a small number of patients who had not previously received an ESA. Currently underway is a phase 3 trial looking at luspatercept in ESA-naive, lower-risk MDS patients with anemia who require RBC transfusions.
Luspatercept would be a useful therapy to have in clinic for patients with ring sideroblasts, who represent about 25% of patients overall, according to MDS expert David Steensma, MD, of Dana-Farber Cancer Institute and Harvard Medical School, Boston.
“It’s been 12 years since we had an FDA [Food and Drug Administration]-approved drug in MDS, and there have been seven in acute myeloid leukemia in the last year and a half, so it’s our turn, I think,” said Dr. Steensma, who moderated the press conference.
