Heidelberg Pharma and Partner Magenta to Present Initial Clinical Data on their Antibody Drug Conjugates at the ASH Annual Meeting 2022 - Seite 2

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.

About Heidelberg Pharma's proprietary ATAC technology

Antibody drug conjugates (ADCs) combine the high affinity and specificity of antibodies with the potency of cytotoxic small molecules for the treatment of cancer. ATACs are ADCs whose active ingredient is made up of amatoxin molecules. Amatoxins are small bicyclic peptides naturally occurring in the death cap mushroom. They inhibit mRNA transcription by binding to RNA polymerase II, a mechanism that is crucial for the survival of eukaryotic cells. In preclinical testing, ATACs have been shown to be highly efficacious, overcoming frequently encountered resistance mechanisms and combating even quiescent tumor cells.
