AT-101 is an orally-active, pan-Bcl-2 inhibitor (including Bcl-2, Bcl-xL, Bcl-w, and Mcl-1 inhibition) that has been shown to induce apoptosis directly by operating as a BH3 mimetic and indirectly as an independent upregulator of Noxa and Puma. By blocking the binding of Bcl-2 family members with proapoptotic proteins and upregulating specific proapoptotic factors, AT-101 lowers the threshold for cancer cells to undergo apoptosis in various tumor types. In Phase I and Phase II trials, AT-101 has demonstrated single-agent cytoreductive activity in several cancers, including chronic lymphocytic leukemia (CLL), non-Hodgkins lymphoma (NHL), and prostate cancer. Phase II combination trials are ongoing in several cancers, including hormone-refractory prostate cancer and non-small cell lung cancer (with Taxotere(R)), B-cell malignancies (with Rituxan(R)), small cell lung cancer (with Hycamtin(R)), glioma (with Temodar(R), +/- chemoradiotherapy [XRT]) and esophageal cancer (with docetaxel, 5-fluorouracil and XRT).
About Ascenta Therapeutics
Ascenta Therapeutics, Inc. is a privately-held, clinical-stage biopharmaceutical company that discovers and develops new medicines for the treatment of cancer. The company is headquartered in Malvern, Pennsylvania, and has a preclinical research facility in Shanghai, China. Its technology, licensed from both the National Institutes of Health and the laboratory of Dr. Shaomeng Wang at the University of Michigan, is focused on discovering molecules that restore the natural potential for cancer cells to undergo cell death (apoptosis). Ascenta's lead agent, AT-101, is an orally-active small molecule pan Bcl-2 inhibitor (Bcl-2, Bcl-xL, and Mcl-1) currently in Phase 2 clinical trials in castrate resistant prostate cancer. The Company's preclinical pipeline includes the oral multi-IAP antagonist AT-406, and an HDM2-p53 inhibitor program.
