Description: Birinapant, also known as TL32711, is a synthetic small molecule and peptido mimetic of second mitochondrial-derived activator of caspases (SMAC) and inhibitor of IAP (Inhibitor of Apoptosis Protein) family proteins, with potential antineoplastic activity. As a SMAC mimetic and IAP antagonist, TL32711 binds to and inhibits the activity of IAPs, such as X chromosome-linked IAP (XIAP) and cellular IAPs 1 and 2.

Additional Information

In Phase 1 clinical studies as a single agent and in combination with standard-of-care chemotherapies, TL32711 has demonstrated strong correlation between drug exposure, target coverage and apoptosis induction in tumors at well-tolerated doses as well as promising anti-tumor activity in patients. TL32711 is entering Phase 2 single agent and combination clinical studies in solid tumors and a Phase 1/2 clinical study in acute myeloid leukemia. TetraLogic will execute a Phase 2 clinical program to explore the broad therapeutic potential of Smac mimetics with the support of substantial non-dilutive funding that reduces downstream equity requirements.
