SHANGHAI, China, May 31, 2022-- QureBio Ltd., which invested and incubated by Viva BioInnovator, is a clinical-stage biopharmaceutical company focusing on bi-specific antibodies and other engineered bio-therapeutics for the treatment of cancer, inflammation, and other serious disorders. It announced that its Q-1802 clinical program was selected for presentation at American Society of Clinical Oncology (ASCO) Annual Meetings on June 3–7, 2022, and the abstract of relevant results for this study has been published on ASCO website (

The presentation will showcase the preliminary results of a first-in-human Phase 1a/1b, multicenter, open-label oncology study designed to evaluate the safety and anti-cancer activity Q-1802, a Claudin18.2/PD-L1 bi-specific therapeutic in patients with relapsed or refractory solid tumors after standard therapies. Professor Lin Shen from Peking University Cancer Hospital and Institute leads this study. The key data from the mono-therapy of Q-1802 in both dose-escalation and dose-expansion studies demonstrate excellent safety, tolerability, and preliminary anti-tumor activities of Q-1802 at the dose up to 10 mpk.

The abstract for the study is found in 2022-ASCO-Annual –Meeting Abstracts (#2568). First Author, Dr. Jifang Gong from the Department of Gastrointestinal Oncology, Peking University Cancer Hospital and Institute will present the relevant results on Sunday, June 5, 2022.

About Q-1802
Q-1802, a humanized bi-specific antibody, is the first FDA-approved Claudin18.2/PD-L1 bi-specific therapeutic to enter clinical trial. In animal model studies, Q-1802 demonstrates both superior anti-tumor activities and excellent safety profiles. It recruits multiple immune mechanisms to kill tumor cells, offering a novel therapeutic opportunity for Claudin18.2 positive solid tumors. Q-1802 also exhibits robust physicochemical properties and superb productivity with titers exceeding 4 grams per liter.
