- Increased Screening Rate: Greenwich LifeSciences has accelerated patient screening in its pivotal Phase 3 trial FLAMINGO-01 to over 800 patients per year, reflecting a 33% increase due to new clinical sites activated in 2025 and growing patient momentum at existing centers, which may enhance the company's market position in breast cancer immunotherapy.
- Optimistic Recruitment Outlook: CEO Snehal Patel noted that, despite having screened over 1,000 patients, the company “may not have yet seen the peak screen rate for the study,” indicating optimism about continued enrollment growth that could expedite the clinical trial's progress.
- Preliminary Efficacy Analysis: In the non-HLA-A*02 arm, preliminary analysis showed an approximately 80% reduction in recurrence rates after the primary immunization series, consistent with earlier Phase 2b results, suggesting the potential of GLSI-100 in preventing breast cancer recurrences.
- Global Expansion Plans: The trial, led by Baylor College of Medicine, is enrolling HER2-positive breast cancer patients across U.S. and European sites, with plans for global expansion, and an interim analysis will assess efficacy once half of the required events have occurred.

About GLSI
Greenwich LifeSciences, Inc. is a clinical-stage biopharmaceutical company focused on the development of GP2, an immunotherapy to prevent breast cancer recurrences in patients who have previously undergone surgery. GP2 is a 9-amino acid transmembrane peptide of the human epidermal growth factor receptor 2 (HER2) /neu protein, a cell surface receptor protein that is expressed in a variety of common cancers. It has commenced a Phase III clinical trial, Flamingo-01, an immunotherapy to prevent breast cancer recurrences. GP2 is delivered in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) to induce GP2 peptide-specific immunity. GP2 treatment is administered via an intradermal injection by mixing GP2 peptide and GM-CSF at the time of administration. Its cancer immunotherapy seeks to stimulate an individual's immune system to selectively attack cancer cells while not affecting normal cells or to deliver immune system components to inhibit the spread of cancer.
