Akeso Announced First Patient Dosed in Phase 3 Trial of Ivonescimab versus Tislelizumab for First-line Treatment of Squamous NSCLC
HONG KONG, Aug. 18, 2023 /PRNewswire/ -- Akeso Biopharma Inc.. ("Akeso", 9926. HK) announced today that the first patient has been dosed in a head-to-head phase III trial of ivonescimab, a potential first-in-class investigational PD-1/VEGF bi-specific antibody discovered by Akeso. The Phase III trial will evaluate the clinical efficacy and assess the safety of ivonescimab compared with tislelizumab in combination with chemotherapy as first-line treatment of locally advanced or metastatic squamous non-small cell lung cancer (sq-NSCLC).
The international multicenter Phase III clinical trial of ivonescimab for this specific indication is currently ongoing. According to the latest clinical development plan for ivonescimab released by Summit Therapeutics, a partner of Akeso in the global development of ivonescimab, the international multicenter Phase III clinical study of ivonescimab in combination with chemotherapy versus pembrolizumab in combination with chemotherapy for first-line treatment of metastatic sq-NSCLC (HARMONi-3 ) is scheduled to dose the first patient in the second half of 2023.
The use of PD- (L)1 inhibitors in conjunction with chemotherapy is the current standard of care (SOC) for lung cancer worldwide, especially in the United States and China. However, despite this approach, there is still significant room for improvement in terms of prognosis, as there remains an extensive unmet need.
Currently, ivonescimab has been engaged in several Phase III head-to-head trials compared with standard of care PD-(L)1 inhibitors for lung cancer in developed countries worldwide, including China, the United States, Europe, and other developed countries. Akeso and Summit are determined and confident in pursuing stronger evidence-based medical research for ivonescimab, with a specific emphasis on the drug's clinical value. These efforts aim to expedite the drug's time to market and ensure its commercial success on a global scale.
Following an acceptance of marketing application for an indication of ivonescimab by the China CDE, four pivotal registrational Phase III clinical trials have been initiated/are being conducted worldwide, including three head-to-head trials with PD-1 monoclonal antibody as the positive control drug:
Ivonescimab is a potential first-in-class investigational PD-1/VEGF bi-specific antibody discovered by Akeso and is believed to be the PD-1 / VEGF bispecific antibody that is most advanced in the clinic. Ivonescimab is currently developed by Akeso (known as AK112) in China and Australia and Summit (known as SMT112) in the United States, Canada, Europe, and Japan (Summit's license territories). It combines the effects of immunotherapy via a blockade of PD-1 with the anti-angiogenesis effects associated with blocking VEGF into a single molecule. Ivonescimab is currently engaged in multiple Phase III clinical trials worldwide.
