The ASCO Annual Meeting showcases the most cutting-edge research in clinical oncology and state-of-the-art advanced cancer therapies and is the world's most influential and prominent scientific gathering of the clinical oncology community. This year's ASCO Annual Meeting will take place both online and in-person at the McCormick Place, Chicago, IL, United States of America, on June 2–6, 2023.

"We are pleased to have the opportunity to present our clinical results at the ASCO Annual Meeting for the sixth consecutive year and witness the strong recognition of our global innovation and clinical development capabilities," said Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma. "This year, we will present the first dataset of lisaftoclax for the treatment of Waldenström macroglobulinemia (WM). In addition, we will share updated results of alrizomadlin plus pembrolizumab in patients with cutaneous melanoma, olverembatinib in patients with gastrointestinal stromal tumor (GIST), as well as APG-2449 in patients with non-small-cell lung cancer (NSCLC). Moving ahead, we will continue accelerating our global clinical development programs in efforts to bring more treatment options to patients in need."

These four clinical studies to be presented at this year's ASCO Annual Meeting are as follows:
