“RA101495 SC has the potential to provide patients with a more convenient, flexible, and accessible first-line treatment for PNH, gMG, and other lifelong, complement-mediated diseases,” said Mr. King. “With compelling clinical data to date, strong support from the investigator community, and a focused clinical strategy, now is a uniquely exciting time to join the company. I look forward to working with the talented and dedicated team at Ra Pharma to build a plan for commercializing this promising treatment candidate.”
