About YmAbs:

YmAbs is a clinical stage biopharmaceutical company focused on developing new cancer treatments through immunotherapies. Our lead antibody programs target GD2 and B7-H3. In addition, YmAbs utilizes its platform technologies to create next-generation humanized, affinity matured bispecific antibodies. To further improve our bispecific antibodies, we are collaborating on the development of a novel human protein tag that dimerizes T-cell engaging bispecific antibodies, which enables higher tumor binding and results in a longer serum half-life and a significantly greater T-cell mediated killing of tumor cells. Our treatments could potentially reduce longer-term toxicities associated with current chemotherapeutics and provide the potential for curative therapy even for patients with widespread disease. YmAbs' goal is to drive multiple product candidates in select solid tumor cancers to FDA approval. Each candidate has the potential to treat a variety of high-risk cancers.
