Ascentage Pharma's Bcl-2 Inhibitor APG-2575 Granted Orphan Drug Designation by the FDA for the Treatment of Waldenström Macroglobulinemia

SUZHOU, China and ROCKVILLE, Md., July 15, 2020 /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 the US Food and Drug Administration (FDA) has granted APG-2575, a novel Bcl-2 inhibitor being developed by the company, an Orphan Drug Designation (ODD) for the treatment of Waldenström macroglobulinemia (WM). This is the first ODD granted to APG-2575, and the second ODD Ascentage Pharma received from the FDA, following the previous ODD granted to the company's third-generation BCR-ABL inhibitor HQP1351 in May 2020 for the treatment of chronic myeloid leukemia.

The term "orphan drugs" refers to pharmaceutical products developed for the prevention, diagnosis, and treatment of rare diseases or conditions. In the United States, an orphan disease is defined as a disease or condition with a prevalence of less than 200,000 patients in the country. Since the Orphan Drug Act was passed in 1983, the US government has provided incentives and policy support to encourage development of orphan drugs. This ODD from the FDA qualifies APG-2575 for various development incentives, including a tax credit on expenditures incurred in clinical studies, a waiver of the New Drug Application (NDA) fee, research grant awarded by the FDA, and most importantly, 7 years of US market exclusivity upon approval for the treatment of WM.

WM is a type of lymphocytic lymphoma characterized by the bone marrow infiltration of lymphoplasmacytic cells with elevated monoclonal immunoglobulin M (IgM). WM is a rare disease that accounts for less than 2% of all non-Hodgkin's lymphoma (NHL) patients in the US[1].

Treatment recommendations for WM from current NCCN guidelines suggest an objective response rate (ORR) of ~80% with current therapies; however, these therapies deliver a very low rate of very good partial response (VGPR) or deeper responses (~20% or lower), with most patients experiencing disease progression after initial response. Furthermore, patients are diagnosed with WM at a median age of 70, when many of them are intolerant of existing therapies because of poor health conditions, representing a significant unmet medical need for more effective and safer therapies.

APG-2575 is a novel, orally administered Bcl-2 selective inhibitor being developed by Ascentage Pharma. APG-2575 is designed to treat a variety of hematologic malignancies by selectively blocking Bcl-2 to restore the normal apoptosis process in cancer cells. Beside VENCLEXTA® (venetoclax), APG-2575 is one of the few Bcl-2 selective inhibitors currently in active clinical development worldwide and the first China-developed Bcl-2 selective inhibitor having entered clinical trials in China. APG-2575 has received clearances and approvals for multiple Phase Ib/II clinical studies in China, Australia, and the US in a range of hematologic malignancies globally, including a global multicenter Phase Ib/II study designed to evaluate the safety, tolerability, and efficacy of APG-2575 as a single agent or in combination with ibrutinib/rituximab for the treatment of patients with WM.

"WM represents an unmet medical need globally. APG-2575 is a key drug candidate in Ascentage Pharma's pipeline targeting apoptosis. This ODD by the US FDA for the treatment of WM marks an important milestone in the global development and commercialization of APG-2575," said Dr. Dajun Yang, Chairman & CEO of Ascentage Pharma. "All the policy support and incentives as a result of this ODD will help us accelerate the global clinical development of APG-2575, which we hope will soon transform to benefit more patients."
