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 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.

The first four patient cohorts and dose levels of the clinical study have been completed and proved to be safe and well tolerated. Currently, the trial is enrolling patients in the fifth cohort.
