Gamida Cell Ltd.(Nasdaq: GMDA), a leading cellular and immune therapeutics company, announced the publication of data from the previously reported, multi-center Phase 1/2 clinical study evaluating the safety and efficacy of NiCord® as a stand-alone, hematopoietic stem cell (bone marrow) transplant in the Journal of Clinical Oncology1,2. NiCord is an investigational product candidate in Phase 3 development as a universal bone marrow transplant solution for patients with high-risk hematologic malignancies, or blood cancers (see also Gamida Cell Ltd.).
Results from the Phase 1/2 study showed that patients transplanted with NiCord had rapid and durable engraftment of neutrophils and platelets, as well as prompt immune reconstitution. The median time to neutrophil recovery was shortened by nearly 50 percent for patients who received NiCord compared to a retrospective cohort of patients who received standard umbilical cord blood. NiCord also demonstrated an acceptable safety profile for patients undergoing bone marrow transplant.
“In this study, patients who received NiCord had a clinically meaningful reduction in their time to neutrophil and platelet recovery compared to a retrospective cohort of patients who received a standard umbilical cord blood transplant. The neutrophil recovery observed with NiCord also resulted in fewer days spent in the hospital compared to the comparator cohort,” said Mitchell Horwitz, M.D., principal investigator and professor of medicine at the Duke Cancer Institute. “These data suggest a potential step toward making stem cell transplantation safer and more accessible to patients with lethal blood cancers.”
Despite the curative potential of bone marrow transplants, it is estimated that more than 40 percent of eligible patients do not receive one for various reasons, including finding a matched donor.3 While umbilical cord blood provides a source of stem cells for patients who do not have a matched related donor, it provides a smaller number of stem cells, which can delay engraftment and put patients at a greater risk for prolonged hospitalizations and life-threatening infections. NiCord is designed to address these limitations by offering a therapeutic dose of expanded cells while preserving the functional characteristics of stem cells. NiCord Phase 1/2 Study Design and ResultsThe publication, “Phase I/II study of stem cell transplantation using a single cord blood unit expanded ex vivo with nicotinamide,” described results from the completed multicenter, Phase 1/2 clinical trial of NiCord in 36 patients with high-risk hematologic malignancies and no readily available matched sibling or matched unrelated adult donor. The key primary endpoint was the cumulative incidence of neutrophil engraftment at 42 days. Additionally, the NiCord patient cohort was compared to a retrospective cohort of patients who received standard cord blood transplant using data from the Center for International Blood and Marrow Transplant Research (CIBMTR).
