K Pharma,Inc.

K Pharma is a Keio University School of Medicine-originated biotech venture focused on two core businesses: iPS drug discovery (iPS創薬) and regenerative medicine, both leveraging induced pluripotent stem cell (iPS cell) technology. The company develops drug candidates for central nervous system diseases—including ALS, Alzheimer's disease, and spinal cord injury—by using disease-specific iPS cell-derived neurons for phenotypic screening and drug repositioning. In parallel, it is advancing allogeneic iPS cell-derived neural cell transplantation therapies targeting spinal cord injury and stroke, with research conducted in collaboration with Keio University and industry partners across the value chain.
