Ascentage Pharma to Release Updated Clinical Results of HQP1351 (Olverembatinib) in Drug-Resistant Chronic Myeloid Leukemia in an Oral Presentation at the American Society of Hematology Annual Meeting

SUZHOU, China and ROCKVILLE, Md., Nov. 8, 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 results from two pivotal Phase II studies of the company's novel BCR-ABL inhibitor, HQP1351 (olverembatinib), have been accepted for oral presentation at the 62nd American Society of Hematology (ASH) Annual Meeting. Qian Jiang, M.D., who will be presenting, and Xiaojun Huang, M.D. from the Hematology Department of Peking University People's Hospital, are the principal investigators of these studies. Following the data releases in 2018 and 2019, this will be the third time that Ascentage Pharma has presented updated clinical data of HQP1351 at the ASH Annual Meeting. Being accepted by ASH for oral presentation for three consecutive years signifies the recognition of HQP1351's safety and efficacy profiles by the international hematology community.

The 62nd ASH Annual Meeting will be held in a virtual format online from December 5 to 8, 2020. The ASH Annual Meetings are the largest gathering of the international hematology field, bringing together the latest and most cutting-edge research and development in hematology.

HQP1351 is a novel third-generation BCR-ABL tyrosine kinase inhibitor (TKI) being developed by Ascentage Pharma for the treatment of patients with chronic myeloid leukemia (CML) resistant to first- and second-generation TKIs. The results that will be released through the oral presentation are from the two pivotal Phase II trials of HQP1351 in patients with TKI-resistant and T315I-mutant CML. As of March 23, 2020, the pivotal Phase II HQP1351-CC201 trial enrolled a total of 41 patients with CML in the chronic phase (CML-CP); and as of February 11, 2020, the pivotal Phase II HQP1351-CC202 trial enrolled a total of 23 patients with CML in the accelerated phase (CML-AP). Results from those two trials of HQP1351 have shown favorable efficacy and tolerability in patients with TKI-resistant and T315I-mutant CML-CP and CML-AP.

Based on the results from these two pivotal Phase II trials, Ascentage Pharma submitted a New Drug Application (NDA) for HQP1351 for the treatment of patients with T315I-mutant CML-CP and CML-AP in China this year. The NDA has been subsequently granted Priority Review status.
