Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in discovering, developing and commercializing both first- and best-in-class therapies for hematological malignancies, announced today that its novel BCR-ABL1 tyrosine kinase inhibitor (TKI), olverembatinib, has been approved by the Pharmaceutical Administration Bureau (ISAF) of the Macau Special Administrative Region (SAR) of the People’s Republic of China for the treatment of adult patients with tyrosine kinase inhibitors (TKI)-resistant chronic-phase chronic myeloid leukemia (CML-CP) or accelerated-phase CML (CML-AP) harboring the T315I mutation; and adult patients with CML-CP resistant to and/or intolerant of first-and second-generation TKIs. This approval marks another major milestone for olverembatinib following initial approvals granted to the drug in the Chinese mainland for the above indications.

Olverembatinib, a novel drug developed by Ascentage Pharma with support from the National Major New Drug Development program, is the first third-generation BCR-ABL1 inhibitor approved by China’s National Medical Products Administration (NMPA). As a potential global best-in-class drug that can effectively target BCR-ABL1 and a spectrum of BCR-ABL1 mutants, including the T315I mutation, clinical trial results of olverembatinib have already been included in the National Comprehensive Cancer Network (NCCN) guidelines for the management of CML.1 Olverembatinib is being jointly commercialized in China by Ascentage Pharma and Innovent Biologics. All lead drug candidates are being studied as they are an investigational drug and not approved in the US.

“Olverembatinib has the potential to be a global best-in-class drug. We are glad that the drug is set to benefit patients with CML in Macau, China, with the approval marking another major milestone in the clinical development of olverembatinib,” said Dr. Dajun Yang, Chairman and CEO of Ascentage Pharma. “Since its inception, Ascentage Pharma has steadfastly committed to its mission of addressing unmet clinical needs in China and around the world. We are confident that over time, olverembatinib and our other investigational drugs will bring greater benefits to more patients globally.”
