HDP-101 is a BCMA antibody-Amanitin conjugate for the treatment of relapsed or refractory multiple myeloma, a bone marrow cancer with high unmet medical need. The first part of the ongoing trial is a Phase I dose escalation study to determine an optimal and safe dose of HDP-101 for the Phase II part of the study. It is planned to treat up to 36 patients who will receive HDP‑101 intravenously every 3 weeks. During this part of the trial, tolerability of different dose levels will be evaluated.
