Summit Therapeutics completes enrollment in Phase III HARMONi trial

Summit Therapeutics announced that the company has completed enrollment in our HARMONi clinical trial, a multi-regional Phase III study sponsored by Summit evaluating ivonescimab plus platinum-doublet chemotherapy vs. placebo plus platinum-doublet chemotherapy with epidermal growth factor receptor-mutated, locally advanced or metastatic non-squamous non-small cell lung cancer who have progressed after treatment with a 3rd generation EGFR tyrosine kinase inhibitor. HARMONi completed enrolling patients from sites in North America, Europe, and China. This is a clinical setting with a patient population where PD-1 monoclonal antibodies have previously been unsuccessful in Phase III global clinical trials. “I would like to sincerely thank the investigators, site coordinators, Team Summit, and, most importantly, the patients around the world who are participating in the HARMONi study,” said Dr. Maky Zanganeh, Chief Executive Officer and President of Summit. “Completing enrollment in the first global study for ivonescimab is a credit to the growing belief in the potential for ivonescimab to make a significant difference in the lives of patients around the world.” In addition, the U.S. Food and Drug Administration has granted Fast Track designation for the proposed use of ivonescimab in combination with platinum-based chemotherapy for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR mutation, who have experienced disease progression following EGFR-TKI therapy.
