SUZHOU, China and ROCKVILLE, Md., Oct. 23, 2023 /PRNewswire/ -- Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in developing novel therapies for cancer, chronic hepatitis B (CHB), and age-related diseases, announced today that it has released the latest clinical data of its dual Bcl-2/Bcl-xL inhibitor, APG-1252 (pelcitoclax), combined with osimertinib for the treatment of patients with EGFR-mutant non-small cell lung cancer (NSCLC) in a Mini Oral at the 2023 European Society of Medical Oncology (ESMO) Congress.
Developed by Ascentage Pharma, pelcitoclax is a potential best-in-class novel dual Bcl-2/Bcl-xL inhibitor that can restore the apoptosis of cancer cells by selectively inhibiting Bcl-2 and Bcl-xL proteins, thus delivering its therapeutic effects on a range of solid tumors and hematologic malignancies.
The clinical data presented at the ESMO Congress this year demonstrated promising therapeutic utility of pelcitoclax combined with osimertinib in patients with EGFR-mutant NSCLC. Those results show that among the 26 EGFR-tyrosine kinase inhibitor (TKI)-naïve patients, 21 partial responses (PRs) were observed, resulting in an objective response rate (ORR) of 80.8%; while among the 16 EGFR-TKI naïve patients with TP53 and EGFR-mutations, 14 PRs were observed, resulting in an ORR of 87.5%.
Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma, said, "Currently, there are many challenges in the treatment of NSCLC. Among them, TP53 and EGFR mutations can significantly affect the prognosis of patients with NSCLC, and there is no standard of care treatment for this subtype of NSCLC. At the ESMO 2023, we presented the latest clinical data that continued to suggest encouraging therapeutic potential of pelcitoclax combined with osimertinib in EGFR-TKI-naïve patients with TP53- and EGFR-mutant NSCLC.
In earlier studies, pelcitoclax combined with osimertinib demonstrated clinical potential for the treatment of patients with EGFR-mutant advanced NSCLC resistant to EGFR-TKIs. Adding to the body of evidence, updated data presented this year revealed clinical potential of the combination regimen in patients resistant to third-generation EGFR-TKIs. Moving forward, we will continue to fulfill our mission of addressing unmet clinical needs in China and around the world and expedite our clinical programs for the benefit of more patients."
Highlights of the data on pelcitoclax presented at the 2023 ESMO Congress are as follows:
