ClinConnect Summary

This is a phase I trial for safety of VPA expanded cord blood stem cells in patients with hematological malignancies undergoing allogeneic stem cell transplantation. The primary endpoint of the study is safety as defined by the incidence of infusion reactions and graft failure, lack of neutrophil engraftment by day +42. The trial will consist of two cohorts. First cohort of 5-7 patients, will undergo double umbilical cord blood (UCB) transplantation. One UCB unit will undergo CD34 selection followed VPA based expansion. CD34 negative portion of that unit will be cryopreserved to be infused ...
