Email Address About Greenwich LifeSciencesGreenwich LifeSciences (NASDAQ:GLSI) is a clinical-stage biotechnology company focused on developing cancer immunotherapies designed to reduce the risk of breast cancer recurrence. The company’s lead product candidate is GLSI-100, an investigational vaccine intended for patients with HER2-positive breast cancer who have completed standard treatment. GLSI-100 combines GP2, a peptide derived from the HER2 protein, with granulocyte-macrophage colony-stimulating factor (GM-CSF), an immune-system stimulant. Greenwich LifeSciences is evaluating the therapy in clinical studies, including the Phase III PRESENT trial, which is designed to assess whether GLSI-100 can help prevent recurrence in eligible patients. Greenwich LifeSciences is headquartered in Houston, Texas, and its activities are centered on the development of GLSI-100 rather than the marketing of approved pharmaceutical products. The company was founded by Snehal Patel, who serves as its chief executive officer.View Greenwich LifeSciences ProfileRead more More Earnings Resources from MarketBeat Earnings Tools Today's Earnings Tomorrow's Earnings Next Week's Earnings Upcoming Earnings Calls Earnings Newsletter Earnings Call Transcripts Earnings Beats & Misses Corporate Guidance Earnings Screener Latest Articles 5 Retail Picks to Watch as the Holiday Shopping Season NearsMarketBeat Week in Review – 10/05 - 10/09Q3 Earnings Could Blow Past Consensus—Be Ready for What Comes NextDelta Air Lines Faces a Fuel Crisis—But There's a Silver LiningPalantir’s Rally Puts Wall Street in Catch-Up Mode Ahead of November EarningsC.H.
