The IND application of BL-M11D1, a CD33-binding ADC, has been cleared by the FDA, and a phase 1 study will commence to evaluate the agent in AML.1
"Our mission at SystImmune is to continue to bring therapies that can provide clinical benefit to patients. The initiation of clinical development for BL-M11D1 emphasizes that commitment,” said Jie D'Elia, MD, chief executive officer of SystImmune, BL-M11D1’s developer, in a press release.
BL-M11D1 is an ADC composed of a CD33 binder and a topoisomerase I inhibitor payload with a stable enzyme-cleavable linker. It is based on the drug gemtuzumab ozogamicin (Myotarg),2 which is already approved by the FDA for the treatment of patients with AML.3
"We are excited to receive the FDA study-may-proceed letter enabling the initiation of our phase 1 study with BL-M11D1. We believe that this novel, potentially best-in-class ADC can offer an important therapeutic option for patients with relapsed/refractory AML and look forward to implementing this study," said Jonathan Cheng, MD, chief medical officer at SystImmune, in the press release.1
According to SystImmune, BL-M11D1 is also being evaluated for the treatment of other hematologic malignancies.2
