MGTA-117 is an Antibody Amanitin Conjugate based on Heidelberg Pharma's proprietary ATAC(R) technology and developed by Magenta. A dose escalation study will test the tolerability, pharmacokinetics, pharmacodynamics, and safety of MGTA-117 in patients with relapsed/refractory acute myeloid leukemia and myelodysplasia-excess blasts.

Prof. Andreas Pahl, CSO of Heidelberg Pharma AG, commented: "We congratulate Magenta for this great achievement, and we are very proud that following our own ATAC(R) candidate HDP-101 another ATAC(R) based on our technology has entered the clinical stage. We are convinced that our ATAC(R) technology can provide highly effective and well-tolerated cancer therapies and we are looking forward to seeing initial data from the study."


About Heidelberg Pharma's proprietary ATAC(R) 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. Antibody Targeted Amanitin Conjugates (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.
