[{"type":"text","content":"\nSummit Therapeutics is Currently Enrolling in a Phase III Study with Additional Phase III Study Planned for Third Quarter 2023 for Ivonescimab\n\n\n MENLO PARK, Calif.--(BUSINESS WIRE)--\nSummit Therapeutics Inc. (NASDAQ: SMMT) (“Summit,” “we,” or the “Company”) today announced that data for its novel, potential first-in-class investigational bispecific antibody, ivonescimab, will be presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, IL. The poster with updated clinical data from Phase II clinical trials will be displayed on Sunday June 4 from 8:00 to 11:00am Central Time during the Lung Cancer – Non-Small Cell Metastatic Poster Session.\n\n\nThe poster, which is presented by Dr. Li Zhang, Sun Yat-Sen University Cancer Center1 with data generated and analyzed by our collaboration and licensing partner, Akeso, Inc. (HKEX Code: 9926.HK), provides updated results from the Phase II study (NCT04736823) centered around the cohort of patients in which ivonescimab is combined with chemotherapy (n=135) for first line treatment of advanced or metastatic non-small cell lung cancer (NSCLC) in patients without actionable genomic alterations (i.e., positive for endothelial growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK)). The poster provides updated data supporting promising anti-tumor activity of ivonescimab in first line advanced or metastatic NSCLC, while displaying that ivonescimab may have an acceptable safety profile in combination with platinum-doublet chemotherapy for patients with squamous or non-squamous advanced or metastatic NSCLC in this clinical study.\n\n\nIvonescimab, known as SMT112 in the United States, Canada, Europe, and Japan, and as AK112 in China and Australia, is a novel, potential first-in-class investigational bispecific antibody combining the effects of immunotherapy via a blockade of PD-1 with the anti-angiogenesis effects associated with blocking VEGF into a single molecule. There is higher expression (presence) of both PD-1 and VEGF in tumor tissue and the tumor microenvironment (TME) as compared to normal, healthy tissue in the body. Ivonescimab’s tetravalent structure (four binding sites) enables higher avidity (accumulated strength of multiple binding interactions) with over 10 fold increased binding affinity to PD-1 in the presence of VE...
