SUZHOU, China, and ROCKVILLE, Md., June 7, 2022 /PRNewswire/ -- scentage Pharma (6855.HK), a global biopharmaceutical company engaged in developing novel therapies for cancers, chronic hepatitis B (CHB), and age-related diseases, today announced that it has released the updated results from a Phase II study of the MDM2-p53 inhibitor alrizomadlin (APG-115) plus pembrolizumab in adults and children with various solid tumors in a Poster Discussion session at the 58th American Society of Clinical Oncology (ASCO) Annual Meeting.
Entering the fifth consecutive year in which its abstracts were selected for presentations by the ASCO Annual Meeting, Ascentage Pharma showcased results from multiple clinical trials of its five drug candidates, including the much-anticipated data of alrizomadlin plus pembrolizumab, updated from the data at last year's oral presentation at the ASCO Annual Meeting. The updated results further validate the combination therapy's efficacy in patients with immuno-oncologic- (I-O) drug-resistant or recurrent melanoma, including two complete responses (CRs), an objective response rate (ORR) of 11% and a disease control rate (DCR) of 57%. The abstract also reports favorable clinical benefit in patients with malignant peripheral nerve sheath tumour (MPNST), demonstrated by a DCR of 50%. MPNST is a rare pediatric type of sarcoma lacking effective treatment options.
"Ascentage's novel oral MDM2 inhibitor (alrizomadlin APG-115) continues to be well tolerated in combination with pembrolizumab and provides clinical benefit in several I-O relapse refractory tumor types, specifically various melanoma subtypes as well as MPNST, a rare pediatric sarcoma tumor with no available approved therapies", said Dr Bartosz Chmielowski, MD, Associate Professor from the Melanoma and Sarcoma program at UCLA, who presented the updated results at ASCO 2022.
Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma, commented, "Alrizomadlin, a China-developed novel drug with first-in-class potential, is the first MDM2-p53 inhibitor entering clinical studies in China. These data we presented at this year's ASCO Annual Meeting validates alrizomadlin's therapeutic potential in patients with solid tumors that progressed on I-O drugs, thus signaling a potential new treatment option for patients with solid tumors. Furthermore, we are proud to be able to present clinical development progress for a number of Ascentage Pharma's drug candidates, which highlight our capabilities in global innovation. Honoring our mission of addressing unmet clinical needs in China and around the world, we are now accelerating our clinical programs to bring more safe and effective therapeutics to patients in need."
