Ascentage Pharma Declares a New Drug Software for Its Novel Bcl-2 Inhibitor Lisaftoclax Accepted and Really helpful Precedence Evaluation Designation by CDE of China NMPA

ROCKVILLE, Md. and SUZHOU, China, Nov. 17, 2024 /PRNewswire/ — Ascentage Pharma (6855.HK), a worldwide biopharmaceutical firm engaged in discovering, growing and commercializing therapies to deal with world unmet medical wants primarily for malignancies, right this moment introduced {that a} New Drug Software (NDA) for its inhouse developed investigational novel Bcl-2 selective inhibitor, lisaftoclax (APG-2575), for the therapy of sufferers with relapsed or refractory (r/r) power lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) has been accepted and really helpful the Precedence Evaluation designation by the Heart for Drug Analysis (CDE) of China’s Nationwide Medical (TASE:) Merchandise Administration (NMPA). This NDA, the primary for a domestically developed Bcl-2 inhibitor in China, may doubtlessly lead lisaftoclax to change into the second Bcl-2 inhibitor authorised anyplace on this planet.

This NDA relies on outcomes from a pivotal registrational Section II research in China (APG2575CC201) that evaluated the efficacy and security of lisaftoclax in sufferers with r/r CLL/SLL. The first endpoint of the research is the general response price (ORR).

CLL/SLL is a hematologic malignancy brought on by mature B-cell neoplasms. It primarily impacts older populations and is among the many commonest leukemia subtypes within the Western World, with over 100,000 new diagnoses reported globally every year¹. In China, the place the incidence price of CLL/SLL is decrease than that of the western nations, the illness is going on at a quickly rising price, with a youthful age of onset and better aggressiveness². SLL and CLL are two totally different manifestations of the identical illness and roughly 20% of all SLL instances would progress to CLL³. Remedies similar to immunotherapies and Bruton’s tyrosine kinase inhibitors (BTKis) have considerably improved sufferers’ responses to preliminary therapy. Nevertheless, because of the limitations of current therapy choices, the poor prognosis of sufferers, extreme impression on sufferers’ high quality of life and excessive complexity of the illness, sufferers with r/r CLL/SLL are in determined want for brand new therapy choices which are secure and efficient.

The introduction of Bcl-2 inhibitors has additional revolutionized the therapy of CLL/SLL. Bcl-2 is an apoptosis suppressor issue that regulates cell survival by controlling mitochondrial membrane permeability. It suppresses apoptosis by inhibiting the discharge of cytochrome C from mitochondria or by binding to apoptotic activators to inhibit the exercise of caspase. The overexpression of Bcl-2, present in a wide range of hematologic malignancies, notably CLL/SLL, is a key mechanism by which tumor cells evade apoptosis.

Nevertheless, the event of Bcl-2 as a therapeutic goal is difficult primarily as a result of its mechanism of motion relies on the protein-protein interplay (PPI). The binding interface of Bcl-2 is comparatively giant, making it tough for small-molecule inhibitors to exert blocking results. Moreover, the Bcl-2 protein is positioned on the mitochondrial membrane, and mitochondria, with its double-membrane construction, is among the many most advanced and difficult mobile elements. Medicine should first penetrate the cell membrane earlier than they will additional act on the mitochondrial membrane. In practically 40 years for the reason that discovery of this goal, just one Bcl-2 inhibitor has been authorised globally, a actuality highlighting the immense problem and challenges on this discipline of analysis and improvement. In western nations, the therapy of CLL/SLL has entered a brand new period of chemotherapy-free and fixed-duration regimens, whereas no Bcl-2 inhibitor has been authorised in China on this therapeutic space. Due to this fact, sufferers in China have an pressing unmet want for such novel therapies that may provide each efficacy and security.

Lisaftoclax is a novel, investigational orally administered small-molecule Bcl-2 selective inhibitor being developed by Ascentage Pharma to deal with sufferers with malignancies by selectively blocking the antiapoptotic protein Bcl-2 and therefore restoring the traditional apoptosis course of in most cancers cells. Lisaftoclax is the primary Bcl-2 inhibitor in China and the second anyplace globally that has demonstrated compelling scientific profit and entered a pivotal registrational research. Lisaftoclax has broad therapeutic potential for a wide range of hematologic malignancies and strong tumors, notably as a single agent and in mixtures in CLL/SLL. Lisaftoclax is a possible drug which will provide sufferers a secure, efficient, and simple to make use of therapy choice.

Lisaftoclax is being evaluated in a number of registrational Section III research, together with a worldwide registrational Section III research of lisaftoclax together with a BTKi in beforehand handled sufferers with CLL/SLL (cleared by the US FDA); a worldwide registrational Section III research of lisaftoclax together with acalabrutinib for the first-line therapy of treatment-naïve sufferers with CLL/SLL; a worldwide registrational Section III research of lisaftoclax together with azacitidine (AZA) for the first-line therapy of aged/unfit treatment-naïve sufferers with acute myeloid leukemia (AML) who have been illiberal of ordinary induction chemotherapies; and a worldwide registrational Section III research of lisaftoclax together with AZA for the first-line therapy of newly-diagnosed sufferers with higher-risk myelodysplastic syndrome (MDS).

“Ascentage Pharma’s founding team has over 20 years of deep experience in developing apoptosis-targeted therapies and has made significant strides with the Bcl-2 target,” stated Dr. Dajun Yang, Chairman & CEO of Ascentage Pharma. “To date, only one Bcl-2 inhibitor has been approved globally, which is a reality underscoring the immense difficulty and challenges in this field of research and development. This NDA submission for lisaftoclax could potentially pave the way for lisaftoclax to become the first approved China-developed Bcl-2 inhibitor, thus marking another major milestone that is a culmination of the Ascentage Pharma’s deep commitment and perseverant work in the past 15 years.”

Dr. Yang continued, “Globally, r/r CLL/SLL represents an area of urgent unmet clinical needs. To have successfully advanced lisaftoclax to this point, it is a true testament to Ascentage Pharma’s robust capabilities in global pharmaceutical innovation. Moving forward, we will accelerate the global development of lisaftoclax in other indications to bring benefit to patients as quickly as possible. Remaining steadfastly committed to our mission of addressing unmet clinical needs in China and around the world, we will strive to develop more novel therapeutics for patients in need.”
