Company Presentation

Greenwich LifeSciences, (Nasdaq: GLSI) is a clinical-stage biopharmaceutical company focused on a Phase III clinical trial, Flamingo-01, which is evaluating GLSI-100, an immunotherapy to prevent breast cancer recurrences. GP2 is a 9 amino acid transmembrane peptide of the HER2/neu protein, a cell surface receptor protein that is expressed in a variety of common cancers, including expression in 75% of breast cancers at low (1+), intermediate (2+), and high (3+ or over-expressor) levels. The combination of GP2 + GM-CSF is called GLSI-100. We are currently expanding Flamingo-01 into Europe with plans to open up to 150 sites globally. Flamingo-01 is designed to evaluate the safety and efficacy of GLSI-100 in HER2/neu positive patients with residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment.
