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 an option agreement with Westport Bio, exercisable at the sole discretion of the Company, to in-license a pre-clinical coronavirus vaccine program that is currently at the stage of pre-clinical animal testing. In exchange for the option, the Company has agreed to sponsor research in an aggregate amount of up to $250,000 plus additional license and assignment fees. Westport Bio’s coronavirus vaccine program includes up to 7 vaccine candidates which are designed to complement or improve upon the DNA/RNA based coronavirus vaccines that are in advanced Phase III clinical trials or that have recently been approved by the FDA for emergency use.
Westport Bio’s previous collaboration with an academic team led to a pre-clinically developed vaccine that showed 100% protection against a lethal challenge dose of pneumonic plague in non-human primate and rodent animal models. The collaboration has been expanded to include a coronavirus vaccine program using similar technology. The coronavirus vaccine technology makes use of multiple antigens that would complement strategies that rely solely on the spike protein as the principal antigen. The spike protein of SARS-CoV-2 plays a key role in the receptor recognition and cell membrane fusion process, but there are also other antigens that may be potential targets. In combination, these antigens may offer greater protection and longer duration of protection.
Snehal Patel, CEO of Greenwich LifeSciences, commented, "While we are focused on the upcoming GP2 Phase III breast cancer clinical trial, and are also exploring how to expand the use of GP2 in additional indications through supplemental clinical trials, we have decided to explore the addition of new immunotherapy product candidates to our pipeline at both the pre-clinical and clinical stages of development. The objective of the coronavirus vaccine program is to leverage the development team’s experience in achieving 100% protection against lethal levels of pneumonic plague infection to increase the percent protection and duration of protection of coronavirus vaccines under development. It is not clear how long one will be protected by the current Covid-19 vaccines and none that have been developed to date offer 100% protection. We are hopeful that our approach, which showed 100% protection against pneumonic plague, may lead to greater and longer lasting protection compared to existing Covid-19 vaccines under development."

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.
