Clinical Research Analyst

The expansion of Greenwich LifeSciences' FLAMINGO-01 Phase III clinical trial into Spain marks a significant milestone in the company's efforts to evaluate GLSI-100 for breast cancer recurrence prevention. With 38 Spanish hospitals participating through the GEICAM network, this expansion substantially increases the trial's reach and potential patient pool.

Key points to consider:

• 30 out of 38 sites have conducted site initiation visits (SIVs), with 19 sites already activated. This rapid progress in just three months (May to July) demonstrates efficient execution and strong interest from Spanish healthcare institutions.
• The company's hands-on approach, with in-person visits to 26 out of 38 sites, suggests a commitment to ensuring high-quality treatment and data collection.
• The expansion nearly doubles the number of active sites compared to the US, potentially accelerating patient recruitment and data gathering.

While this progress is promising, investors should note that the impact on the company's financials and timeline to market is not yet clear. The success of the trial will depend on patient recruitment rates, treatment outcomes and the ability to replicate this expansion model in other European countries. The company's ability to manage a multinational trial of this scale will be important for its long-term prospects in the competitive oncology market.

Oncology Specialist

The expansion of the FLAMINGO-01 trial into Spain, leveraging GEICAM's network, is a strategic move that could significantly impact the study of GLSI-100 immunotherapy for breast cancer recurrence prevention. Here's why this matters from an oncological perspective:

• Diverse patient population: Spain's inclusion broadens the genetic and demographic diversity of the study, potentially enhancing the generalizability of results.
• HLA type screening: The mention of HLA type screening is crucial. HLA (Human Leukocyte Antigen) plays a vital role in immune responses and screening for specific types may help identify patients most likely to benefit from GLSI-100.
• Collaborative approach: The partnership with GEICAM, Spain's largest academic breast cancer research network, brings valuable expertise and potentially streamlines patient recruitment.

However, it's important to note that while site activation is progressing well, the real measure of success will be patient enrollment rates and, ultimately, treatment outcomes. The oncology community will be keenly watching for interim results and any signals of efficacy or safety concerns as the trial progresses across multiple countries.

Market Research Analyst

Greenwich LifeSciences' expansion into Spain represents a significant market opportunity and strategic positioning:

• Market Access: By entering Spain, GLSI is tapping into one of Europe's key pharmaceutical markets, potentially paving the way for future commercialization.
• Competitive Edge: The rapid expansion and collaboration with GEICAM could give GLSI an advantage in patient recruitment and data collection over competitors in the breast cancer space.
• Global Presence: The planned expansion to up to 150 sites across six countries (US, Spain, Italy, France, Germany and Poland) positions GLSI as a truly international player in oncology research.

However, investors should consider the following:

• Resource Allocation: Managing a multinational trial requires significant resources. It's important to monitor whether GLSI can maintain this pace of expansion without straining its financial position.
• Regulatory Complexities: Each new country adds layers of regulatory requirements. The company's ability to navigate these efficiently will be key to maintaining momentum.
• Market Reaction: While the expansion is positive, the stock market's reaction may be tempered until concrete patient enrollment numbers or preliminary efficacy data are available.

Overall, this expansion enhances GLSI's potential market reach but also increases operational complexity. The coming months will be critical in determining whether this strategy translates into accelerated trial progress and, ultimately, market value.

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 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.
