Gamida Cell announced the results of a Phase III clinical study of omidubicel presented in an oral session at the Transplantation & Cellular Therapy Meetings of the American Society of Transplantation and Cellular Therapy (ASTCT) and Center for International Blood & Marrow Transplant Research (CIBMTR), or the TCT Meetings. Omidubicel is an advanced cell therapy under development as a potential life-saving allogeneic hematopoietic stem cell transplant solution for patients with hematologic malignancies. This clinical data set was from the international, multi-center, randomized Phase III study of omidubicel that was designed to evaluate the safety and efficacy of omidubicel in patients with high-risk hematologic malignancies undergoing a bone marrow transplant compared to a comparator group of patients who received a standard umbilical cord blood transplant. Details of Phase III Efficacy and Safety Results Shared at the TCT Meetings : Patient demographics including racial and ethnic diversity and baseline characteristics were well-balanced across the two study groups. The study’s intent-to-treat analysis included 125 patients aged 13–65 years with a median age of 41. Diseases included acute lymphoblastic leukemia, acute myelogenous leukemia, chronic myelogenous leukemia, myelodysplastic syndrome or lymphoma. Patients were enrolled at more than 30 clinical centers in the United States, Europe, Asia, and Latin America.Gamida Cell previously reported in May 2020 that the study achieved its primary endpoint, showing that omidubicel demonstrated a statistically significant reduction in time to neutrophil engraftment, a measure of how quickly the stem cells a patient receives in a transplant are established and begin to make healthy new cells, and a key milestone in a patient’s recovery from a bone marrow transplant. The median time to neutrophil engraftment was 12 days for patients randomized to omidubicel compared to 22 days for the comparator group (p<0.001). all three secondary endpoints demonstrated a statistically significant improvement among patients who were randomized to omidubicel in relation to patients randomized to the comparator group (intent-to-treat) . platelet engraftment was significantly accelerated with omidubicel, with 55 percent of patients randomized to omidubicel achieving platelet engraftment at day 42, compared to 35 percent for the comparator (p="0.028)." the rate of infection was significantly reduced for patients randomized to omidubicel, with the cumulative incidence of first grade 2 or grade 3 bacterial or invasive fungal infection for patients randomized to omidubicel of 37 percent, compared to 57 percent for the comparator (p="0.027)." hospitalization in the first 100 days after transplant was also reduced in patients randomized to omidubicel, with a median number of days alive and out of hospital for patients randomized to omidubicel of 60.5 days, compared to 48.0 days for the comparator (p="0.005)." the details of these data were first reported in december 2020. previously unpublished data from the study relating to exploratory endpoints also support the clinical benefit demonstrated by the study’s primary and secondary endpoints. there was no statistically significant difference between the two patient groups related to grade 3 4 acute gvhd (14 percent for omidubicel, 21 percent for the comparator) or all grades chronic gvhd at one year (35 percent for omidubicel, 29 percent for the comparator). non-relapse mortality was shown to be 11 percent for patients randomized to omidubicel and 24 percent for patients randomized to the comparator (p="0.09)." these clinical data results will form the basis of a biologics license application (bla) that gamida cell expects to submit to the fda in the second half of 2021.>
