Sierra Oncology Announces Oral Presentation at European Hematology Association Annual Meeting
Sierra Oncology, Inc. (SRRA) announced that new analyses from the SIMPLIFY-1 and SIMPLIFY-2 studies of momelotinib will be presented at the European Hematology Association Annual Meeting. The oral presentation will focus on findings indicating a significant association between transfusion independence at Week 24 and improved overall survival for myelofibrosis patients. The data suggest higher transfusion independence rates in patients treated with momelotinib. Presentations will occur virtually on June 11, 2021, showcasing the potential long-term benefits of momelotinib, particularly in JAKi-naïve patients.
- New analyses demonstrate a strong correlation between transfusion independence at Week 24 and improved overall survival in myelofibrosis patients treated with momelotinib.
- Higher transfusion independence rates were observed in momelotinib-treated patients (67% in SIMPLIFY-1 and 43% in SIMPLIFY-2) compared to other treatments.
- None.
– Oral presentation for new momelotinib analysis examines association between transfusion independence and overall survival –
– Poster presentation to highlight improved transfusion independence of momelotinib irrespective of baseline degree of anemia, platelet count or transfusion status –
SAN MATEO, Calif., May 12, 2021 /PRNewswire/ - Sierra Oncology, Inc. (SRRA), a late-stage biopharmaceutical company on a quest to deliver targeted therapies that treat rare forms of cancer, today announced abstracts on new analyses from the previously completed SIMPLIFY-1 and SIMPLIFY-2 studies have been accepted into the program for the 2021 Annual Meeting of the European Hematology Association (EHA). An abstract highlighting the association between transfusion independence and improved overall survival in myelofibrosis patients treated with momelotinib has been selected for oral presentation.
"Overall survival remains the gold standard benchmark for oncology therapies. We are excited to showcase these new analyses in an oral presentation demonstrating a strong correlation between achieving or maintaining transfusion independence at Week 24 and overall survival for momelotinib patients in SIMPLIFY-1. A similar trend was seen in SIMPLIFY-2," said Barbara Klencke, MD, Chief Development Officer of Sierra. "Higher rates of transfusion independence at Week 24 were observed in anemic patients receiving momelotinib, regardless of the degree of baseline anemia, and in all subgroups of patients when analyzed either by baseline platelet count or baseline transfusion status as we describe in a separate accepted poster. Together, these data support the potential long-term benefit of achieving or maintaining transfusion independence by inhibiting ACVR1 / ALK2 in addition to JAK1 and JAK2 with momelotinib in myelofibrosis patients, regardless of baseline platelet count, transfusion status or degree of anemia. We look forward to the presentation of the full data sets at the EHA annual meeting next month."
Transfusion Independence is Associated with Improved Overall Survival in Myelofibrosis Patients Receiving Momelotinib
Efficacy data examining the association between transfusion independence and overall survival for momelotinib patients from SIMPLIFY-1 (JAKi-naïve) and SIMPLIFY-2 (JAKi-exposed) will be presented in an oral presentation by Ruben Mesa, MD, Director of the Mays Cancer Center, UT Health San Antonio, MD Anderson Cancer Center.
Previously published data from both SIMPLIFY studies demonstrate robust overall survival for momelotinib-treated patients (median not yet reached in SIMPLIFY-1 and 34.3 months in SIMPLIFY-2). Additionally, previously reported week 24 transfusion independence rates were higher in the momelotinib arms of SIMPLIFY-1 (

Improved Transfusion Independence Rates for Momelotinib vs. Ruxolitinib in Anemic JAKi Naïve Myelofibrosis Patients Independent of Baseline Platelet or Transfusion Status
Progressive anemia is a common occurrence in myelofibrosis, with nearly all patients requiring transfusions as their disease advances. As described above, the analyses in Abstract S202 show that JAKi-naïve patients receiving momelotinib who maintain or achieve transfusion independence at week 24 have favorable overall survival compared to non-responders, with a similar trend observed in SIMPLIFY-2. Therefore, it is important to understand which patients are most likely to achieve transfusion independence at week 24.
Abstract EP1081 will highlight new analyses from SIMPLIFY-1 to demonstrate that the prognostically important week 24 transfusion independence rates in JAK inhibitor-naïve myelofibrosis patients were consistently higher in anemic patients receiving momelotinib compared to ruxolitinib, regardless of the platelet count, transfusion status or degree of anemia at baseline. Data to be featured further support the potential benefits of inhibiting ACVR1 / ALK2 in addition to JAK1 and JAK2 in myelofibrosis patients, and will be presented by Jean-Jacques Kiladjian, MD, PhD, Professor of Clinical Pharmacology, Paris Diderot University; Consultant Hematologist, Head, Clinical Investigation Center, Saint Louis Hospital, Paris, France.
