MT2020-06: A PHASE 1/2 STUDY TO EVALUATE THE SAFETY, TOLERABILITY, AND EFFICACY OF JSP191 FOR HEMATOPOIETIC CELL TRANSPLANTATION CONDITIONING TO ACHIEVE ENGRAFTMENT AND IMMUNE RECONSTITUTION IN SUBJECTS WITH SCID

Recruiting

Phase 1: To evaluate the safety and tolerability of JSP191 and to determine Phase 2 doses of JSP191 as a conditioning agent prior to allogeneic hematopoietic cell transplantation (HCT) in two populations of subjects with severe combined immunodeficiency (SCID): • SCID subjects with history of prior allogeneic HCT but with poor graft function • SCID subjects who are HCT-naïve Phase 2: • To evaluate the efficacy of JSP191 conditioning to enable engraftment of allogeneic CD34+ hematopoietic cells, as determined by CD15+ donor myeloid chimerism • To evaluate the efficacy of JSP191 conditioning to enable immune reconstitution determined by the production of naïve T cells
