Overview
Greenwich Lifesciences Inc (GLSI) is a clinical-stage biopharmaceutical company that specializes in the development of innovative immunotherapy solutions aimed at preventing cancer recurrences. At the heart of its research is GP2, a targeted peptide immunotherapy designed to address breast cancer recurrences by eliciting a focused immune response. The company integrates advanced immunoadjuvant technologies, which enhance the effectiveness of its therapies by boosting the innate and adaptive immune defenses against various cancer types.
Core Business Areas
Greenwich Lifesciences Inc operates within the high-stakes realm of oncology therapeutics. The company’s portfolio includes several product candidates that are in different stages of clinical evaluation.

Greenwich LifeSciences (NASDAQ: GLSI) has reported positive preliminary immune response data from its FLAMINGO-01 Phase III clinical trial evaluating GLSI-100, an immunotherapy for breast cancer recurrence prevention. The data shows increasing immune responses over time in both HLA-A*02 and non-HLA-A*02 patient arms.
Key findings include baseline immune response to GP2 before treatment and increasing response with vaccinations through months 4-6, consistent with Phase IIb trial results. The company has filed patent claims for non-HLA-A*02 patients, potentially doubling eligible patients to 88,000 annually in the US and Europe, with market potential of $8-10 billion per year.
Previous Phase IIb trial demonstrated an 80% or greater reduction in cancer recurrences over 5 years in HER2/neu 3+ patients treated with GLSI-100. The company is considering adding a randomized placebo arm for non-HLA-A*02 patients, effectively creating a second pivotal Phase III trial.
Greenwich LifeSciences (NASDAQ: GLSI) has announced an extension of the lock-up period for shares owned by company directors, officers, and pre-IPO investors until March 31, 2026. This extension represents approximately 66 months from the company's IPO date.
During this lock-up period, these insiders will be restricted from selling their common stock holdings unless modified by the Board of Directors. After the lock-up expiration, daily and periodic trading restrictions will still apply to these shares, subject to Board modification.
The company is currently conducting the Phase III FLAMINGO-01 clinical trial of GLSI-100, an immunotherapy designed to prevent breast cancer recurrences.
Greenwich LifeSciences (NASDAQ: GLSI) has provided an update on the safety data from its Phase III FLAMINGO-01 clinical trial evaluating GLSI-100, an immunotherapy for breast cancer recurrence prevention. The Data Safety Monitoring Board (DSMB) met twice in 2024 and recommended continuing the study without modifications, with no serious adverse events reported.
The update includes comparison with Phase IIb trial results, which showed an 80% or greater reduction in cancer recurrences in HER2/neu 3+ patients treated with GLSI-100. The Phase IIb trial, involving 96 patients across 16 sites, demonstrated no serious adverse events and a well-tolerated safety profile.
Preliminary FLAMINGO-01 safety data analysis shows GP2 immunotherapy continues to be well-tolerated across all study arms, with injection site reactions being the most frequent adverse event. The safety profile is trending similarly to the Phase IIb study, requiring no protocol modifications.
Greenwich LifeSciences (NASDAQ: GLSI) has provided an update on the open label HLA data from its Phase III FLAMINGO-01 trial, which evaluates GLSI-100 immunotherapy for breast cancer recurrence prevention. The analysis reveals that 46% of screened patients have at least one HLA-A*02 allele, meeting the expected 40-50% prevalence rate and supporting sample size estimates for the trial.
The study includes three arms: two blinded arms for HLA-A*02 patients (treatment vs. placebo) and an expanded open-label arm for non-HLA-A*02 patients, recently increased from 100 to 250 participants. Notably, 8% of patients have received HLA-A*02 alleles from both parents, which could potentially lead to greater immune response and efficacy. The trial's design allows for analysis of various HLA combinations and their prevalence across different racial and ethnic groups, which may inform future commercial development strategies.
