Heidelberg Pharma’s Myeloma Drug Gets Fast Track
FDA has granted Heidelberg Pharma a fast track designation for HDP-101 (pamlectabart tismanitin), the company’s lead amanitin-based antibody drug conjugates candidate. The designation was based on data from the ongoing Phase 1-2a study that is evaluating the drug’s safety and antitumor activity in patients with relapsed or refractory multiple myeloma.
HDP-101 is said to be engineered to precisely deliver a potent payload to cancer cells while minimizing harm to healthy cells. The pamlectabart component is a monoclonal antibody that targets the B-cell maturation antigen, a protein overexpressed on the surface of multiple myeloma cells. The tismanitin component is a cytotoxic derivative of alpha-amanitin, a potent poison derived from a mushroom.
