About Breast Cancer and HER2 /new Positivity

One in eight American women will develop invasive breast cancer in her lifetime, with an estimated 282,000 new breast cancer patients and 3.8 million breast cancer survivors in 2021. HER2 /new (human epidermal growth factor receptor 2) is a cell surface receptor protein that is expressed in a variety of common cancers, including 75% of breast cancers at low (1+), intermediate (2+) and high (3+ or over-expressing).

About Greenwich LifeSciences, Inc.

Greenwich LifeSciences is a clinical-stage biopharmaceutical company focused on the development of GP2, an immunotherapy to prevent breast cancer recurrence in patients with previous surgery. GP2 is a 9 amino acid transmembrane peptide of HER2 /new protein. In a randomized, single-blind, placebo-controlled, multicenter (16 sites led by MD Anderson Cancer Center) Phase IIb clinical trial, no recurrence was observed in the HER2 /new Adjuvant 3+ setting after 5 years of median follow-up, if the patient received the 6 primary intradermal injections during the first 6 months (p = 0.0338). Of the 138 patients who have been treated with GP2 to date in 4 clinical trials, treatment with GP2 has been well tolerated and no serious adverse events have been observed related to GP2 immunotherapy. Greenwich LifeSciences plans to begin a Phase III clinical trial using a treatment regimen similar to that of the Phase IIb clinical trial.

About the immune response of GP2 immunotherapy

As previously reported, GP2 immunotherapy generated immune responses specific to GP2, leading to no recurrence of metastatic breast cancer in HER2 /new 3+ population in the Phase IIb clinical trial, thus supporting the mechanism of action of GP2. A statistically significant peak in immunity was achieved after 6 months of treatment with GP2, as measured by both the Dimer Binding Assay and the DTH skin test. HER2 /new The immune response of the 3+ population was similar to that of HER2 /new Immune response of the 1-2+ population, suggesting potential to treat HER2 /new Population 1-2+ (including triple negative breast cancer) with GP2 immunotherapy in combination with trastuzumab (Herceptin) products and other clinically active agents. Broad-based immune response suggests the potential of GP2 to treat other HER2 /new 1-3 + expressing cancers.
