About Greenwich Lifesciences Inc

Greenwich LifeSciences, Inc. engages in the development of a breast cancer immunotherapy designed to prevent the recurrence of breast cancer following surgery. The company is headquartered in Stafford Texas, Texas and currently employs 4 full-time employees. The company went IPO on 2020-09-25. 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. The company 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.
