Jasper Therapeutics, Inc., a clinical-stage biotechnology company, develops therapeutic agents for hematopoietic stem cell transplantation and gene therapies. It focuses on the development and commercialization of therapeutic agents for diseases, such as chronic spontaneous urticaria, lower to intermediate risk myelodysplastic syndrome, and novel conditioning regimens for stem cell transplantation and ex-vivo gene therapy, a technique in which genetic manipulation of cells is performed outside of the body prior to transplantation. The company's lead product candidate is briquilimab, which is in clinical development as a novel therapeutic antibody that clears hematopoietic stem cells from bone marrow in patients prior to undergoing allogeneic stem cell therapy or stem cell gene therapy. It is also developing engineered hematopoietic stem cells product candidates to overcome key limitations of allogeneic and autologous gene-edited stem cell grafts. The company is headquartered in Redwood City, California.
