Ascentage Pharma Establishes Cooperative R&D Agreement (CRADA) with the National Cancer Institute for Clinical Development of Ascentage Pharma's Drug Compound pelcitoclax

SUZHOU, China, and ROCKVILLE, Md., July 19, 2021 /PRNewswire/ -- Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in developing novel therapies for cancers, chronic hepatitis B (CHB), and age-related diseases, today announced that the company has entered into a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI), part of National Institutes of Health, under which they will collaborate on the non-clinical and clinical development of Ascentage Pharma's drug compound pelcitoclax.

Under the terms of the CRADA, Ascentage Pharma and the NCI will collaborate on a series of clinical trials to evaluate the safety and efficacy of pelcitoclax, Ascentage Pharma's dual inhibitor of BCL-2 and BCL-xL proteins, in solid tumors based upon encouraging anti-tumor activity observed in studies conducted by Ascentage Pharma. The NCI may also conduct non-clinical correlative studies that focus on exploring the biologic activity of pelcitoclax, as well as combination studies of the compound with other targeted agents.

As data from the NCI -sponsored studies and other Ascentage-sponsored trials emerge, the NCI and Ascentage will discuss additional studies to support the development of pelcitoclax.

"Our CRADA with the NCI reinforces our commitment to maximize the clinical potential of pelcitoclax in solid tumors and is aligned with our efforts to advance our pipeline," said Dr. Dajun Yang, Chairman & CEO of Ascentage Pharma.

"This CRADA will combine the scientific expertise of the NCI and Ascentage Pharma, in generating additional clinical data that may highlight pelcitoclax's differentiated clinical profile in multiple different indications and address important patient unmet medical need," said Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma.

About Pelcitoclax (APG-1252)

Pelcitoclax (APG-1252) is a novel, dual inhibitor of BCL-2 and BCL-xL proteins developed by Ascentage Pharma and was designed using a prodrug strategy that improves its therapeutic index, decreases cell permeability, and reduces platelet toxicity. Pelcitoclax binds to BCL-2 and BCL-xL molecules with high affinity and in preclinical models exhibits potent antileukemic activity.

In a multicenter, open-label, dose escalation, phase I study, the safety, pharmacokinetics, and preliminary efficacy of pelcitoclax were evaluated in patients with metastatic small-cell lung cancer (SCLC) or other solid tumors (ClinicalTrials.gov Identifier: NCT03080311). To overcome treatment resistance, combining BCL-2 inhibitors with other therapies is also a potentially viable clinical strategy. Currently, pelcitoclax is being evaluated in combination with paclitaxel in relapsed or refractory SCLC (ClinicalTrials.gov Identifier: NCT04210037).
