Gamida Cell Presents Efficacy and Safety Results of Phase 3 Study of Omidubicel in Patients with Hematologic Malignancies at the 47th Annual Meeting of the European Society for Blood and Marrow Transplantation (EBMT)
-Abstract will be shared at Presidential Symposium and featured in this year’s “Live with Best Abstracts” session-
“There is an acute need in stem cell transplantation to treat patients who do not have access to a matched donor, and the results of this global Phase 3 study demonstrate that omidubicel has the potential to address this critical gap,” said Professor
This clinical data set, which was also recently presented at the Transplantation & Cellular Therapy Meetings of the
“The inclusion of the omidubicel Phase 3 results in these prominent sessions at EBMT 2021 and other recent prestigious peer-reviewed settings reinforce the strength of these data and the potential of omidubicel to make a meaningful impact in the hematopoietic bone marrow transplant treatment landscape,” said

Details of Phase 3 Efficacy and Safety Results Shared at EBMT
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
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
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 III/IV 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). Transplants with umbilical cord blood, the comparator, have been historically shown to result in low incidence of GvHD in relation to other graft sources, and in this study, omidubicel demonstrated a similar GvHD profile. 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
Omidubicel is an advanced cell therapy under development as a potential life-saving allogeneic hematopoietic stem cell (bone marrow) transplant solution for patients with hematologic malignancies (blood cancers), for which it has been granted Breakthrough Status by the
Omidubicel is an investigational therapy, and its safety and efficacy have not been established by the FDA or any other health authority.
