Greenwich LifeSciences Inc., a clinical-stage biopharmaceutical company focused on the development of GP2, an immunotherapy to prevent breast cancer recurrences in patients who have previously undergone surgery, has completed the manufacturing of the GP2 active ingredient for its planned Phase III clinical trial. After having met all drug specifications and release criteria in compliance with current Good Manufacturing Practice (cGMP), the GP2 active ingredient has been released for formulation and filling into vials, which is the last step before storage and distribution of GP2 to clinical sites.

Snehal Patel, CEO of Greenwich LifeSciences commented, “We are pleased to have completed this major manufacturing milestone. Last week we completed our IPO, in which members of senior management and directors invested funds aggregating in approximately 15% of the IPO gross proceeds. Our success in scaling up GP2 to large scale cGMP manufacturing and our recent fundraising moves us closer to commencing the upcoming Phase III clinical trial.”

The company’s commercial manufacturing partner, Polypeptide Laboratories, located in San Diego, California and a specialist in the manufacture of clinical and commercial grade peptides, initiated this clinical lot in 2019, which is at a commercial scale that can produce 50,000 doses and treat up to 4,500 patients. In addition, analytical methods were validated and a stability program has been initiated per cGMP requirements.
