Greenwich LifeSciences Announces New Manufacturing Agreement for its Planned Phase III Clinical Trial and Enters into Lease for Office and Lab Space

STAFFORD, Texas--(BUSINESS WIRE)-- Greenwich LifeSciences, Inc. (Nasdaq: GLSI) (the “Company”), 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, today announced that it has entered into a contract for the final formulation and filling of GP2 into vials, which when completed will allow for the storage and distribution of GP2 to clinical sites. The contract manufacturer plans to commence activities in 2021. In addition, the Company has leased office, laboratory, and storage space to provide research, manufacturing, and clinical trial support activities.

Snehal Patel, CEO of Greenwich LifeSciences, commented, “We are pleased to have entered into these key manufacturing and facility agreements, which along with the continued recruitment of key opinion leaders and clinical sites, will be some of the major last steps before commencing the upcoming Phase III clinical trial.”

The Company’s new manufacturing partner specializes in the current Good Manufacturing Practice (cGMP) of formulating, filling, and labeling drug vials and follows the recent completion of the manufacturing of the GP2 active ingredient.

The Company’s new facility is located in Stafford, Texas and will enable the Company to support its manufacturing activities, develop analytical methods, and process clinical trial samples. The facility may also be instrumental in supporting potential additional research and development activities into other drug products that could complement the GP2 immunotherapy platform and expand the pipeline of the Company.

About Greenwich LifeSciences, Inc.

Greenwich LifeSciences is 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. GP2 is a 9 amino acid transmembrane peptide of the HER2/neu protein. In a randomized, single-blinded, placebo-controlled, multi-center (16 sites led by MD Anderson Cancer Center) Phase IIb clinical trial, no recurrences were observed in the HER2/neu 3+ adjuvant setting after median 5 years of follow-up, if the patient received the 6 primary intradermal injections over the first 6 months (p = 0.0338). Of the 138 patients that have been treated with GP2 to date over 4 clinical trials, GP2 treatment was well tolerated and no serious adverse events were observed related to GP2 immunotherapy. Greenwich LifeSciences is planning to commence a Phase III clinical trial using a similar treatment regime as the Phase IIb clinical trial.
