ASCO 2021 | Ascentage Pharma to Announce Updated Data of Lisaftoclax (APG-2575) Demonstrating an ORR of Around 80% and Therapeutic Potential in Patients with R/R CLL/SLL in Oral Presentation
SUZHOU, China and ROCKVILLE, Md., May 19, 2021 /PRNewswire/ -- Ascentage Pharma (6855.HK), a globally focused, clinical-stage biotechnology company engaged in developing novel therapies for cancers, chronic hepatitis B (CHB), and age-related diseases, today announced that an abstract reporting on the first-in-human study of the Bcl-2 inhibitor, lisaftoclax (APG-2575), in patients with relapsed/refractory chronic lymphocytic lymphoma/small lymphocytic lymphoma (R/R CLL/SLL) and other hematologic malignancies has been published in the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting's official website. Results from this global Phase I study demonstrated an ORR of 85.7%, and favorable tolerability and safety profiles in patients with R/R CLL /SLL.
The updated results from this study will be released in an oral presentation at the ASCO Annual Meeting convening on June 4 to 8, 2021. This year, abstracts reporting on four clinical studies of the Ascentage Pharma's three apoptosis-target drug candidates have been selected for presentations at the ASCO Annual Meeting, and two have been selected for oral presentations.
"As a Bcl-2 inhibitor that has demonstrated efficacy, lisaftoclax is the second in the world and the first in China. These data of lisaftoclax suggest the potential for a safe, efficacious, and 'patient-friendly' treatment alternative for patients with R/R CLL and other hematologic malignancies," said Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma. "Moreover, these results which will be presented at the 2021 ASCO Annual Meeting are a testament to our progress in advancing the research and development of apoptosis-targeted therapeutics. We will strive to further accelerate global clinical development programs of these novel therapeutics to benefit patients in China and around the world as early as possible."
Those abstracts to be presented at this year's ASCO Annual Meeting are as follows (two abstracts on APG-115 are simultaneously published in a separate press release):
First-in-human study of lisaftoclax (APG-2575), a novel Bcl-2 inhibitor (Bcl-2i), in patients (pts) with relapsed/refractory (R/R) CLL and other hematologic malignancies (HMs)
Trial in progress: A multicenter phase Ib/II study of pelcitoclax (APG-1252) in combination with paclitaxel in patients with relapsed/refractory small-cell lung cancer (R/R SCLC)
About Lisaftoclax (APG-2575)
Lisaftoclax is a novel, orally administered small-molecule Bcl-2‒selective inhibitor being developed by Ascentage Pharma. Lisaftoclax is designed to treat hematologic malignancies and solid tumors by selectively blocking antiapoptotic protein Bcl-2 to restore the normal apoptosis process in cancer cells. Lisaftoclax is the first China-developed Bcl-2 inhibitor entering clinical development in China. At present, lisaftoclax has been cleared and approved to enter multiple Phase Ib/II studies in the US, China, and Australia, and is being developed globally for the treatment of multiple hematologic malignancies.
About Pelcitoclax (APG-1252)
Pelcitoclax is a novel, highly potent, small-molecule drug designed to restore apoptosis through selective inhibition of Bcl-2 and Bcl-xL proteins. Multiple Phase Ib/II studies of pelcitoclax as a single agent or in combinations for the treatment of a range of advanced tumors, including small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), are being conducted in China, Australia, and the US.
