STAFFORD, Texas, Aug. 01, 2024 (GLOBE NEWSWIRE) -- Greenwich LifeSciences, Inc. (Nasdaq: GLSI) (the "Company"), a clinical-stage biopharmaceutical company focused on its Phase III clinical trial, FLAMINGO-01, which is evaluating GLSI-100, an immunotherapy to prevent breast cancer recurrences, today announced the following update of the expansion of clinical sites into Spain. As previously announced, the Company has partnered with GEICAM, the largest academic breast cancer research network in Spain, where 38 hospitals have agreed to participate in FLAMINGO-01. To date, approximately 30 out of 38 sites have conducted site initiation visits (SIVs). An SIV is followed by site activation, HLA type screening, and study treatment. To date approximately 19 sites have been activated. Multiples sites have begun screening patients for HLA type and have started treating patients. The Company has visited and trained in-person at approximately 26 out of the 38 sites to ensure optimal treatment at each site. In the coming months, GEICAM hopes to complete the remaining SIVs and the Company hopes to visit the remaining sites. "It has been an honor to meet with the excellent study staff, investigators and GEICAM staff across Spain. Their expertise and interest in FLAMINGO-01 is encouraging for the success of the study. We look forward to seeing patient recruitment increase in Spain as other countries in the European Union become active," remarked Jaye Thompson, VP of Clinical and Regulatory Affairs. CEO Snehal Patel commented, "The remarkable progress in Spain, in just May through July, is a testament to the commitment of GEICAM and our team to collaborate and to train the sites together, which we hope will lead to high quality treatment of patients. With just these 30 sites, we have approximately doubled the number of sites that we have opened in the US." The Company may provide updates on the status of other countries in Europe as the clinical trial is expanded to up to 150 sites in the US, Spain, Italy, France, Germany, and Poland. About GEICAM Founded in 1995, GEICAM is a not-for-profit organization leading academic breast cancer research in Spain.

About FLAMINGO-01 and GLSI-100 FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of GLSI-100 (GP2 + GM-CSF) in HER2 positive breast cancer patients who had residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment. The trial is led by Baylor College of Medicine and currently includes US clinical sites from university-based hospitals and cooperative networks with plans to expand into Europe and to open up to 150 sites globally. In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients will be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types will be treated with GLSI-100 in a third arm. The trial has been designed to detect a hazard ratio of 0.3 in invasive breast cancer-free survival, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater.
