Is GP2 vaccine FDA approved?
Our Cancer Immunotherapy GP2 is administered in combination with GM-CSF, an FDA-approved immunoadjuvant, which stimulates the proliferation of antigen presenting cells. Preclinical studies have shown that T cells sensitized against the GP2 peptide demonstrate significant recognition of HER2/neu-expressing tumors.
What is GP2 cancer?
GP2 is a so-called peptide vaccine; it contains peptides (small parts of a protein) derived from HER2, a protein associated with breast cancer. GP2 can be used by the immune system to stimulate certain immune cells called T-cells so they recognize cells expressing HER2.
Where is Greenwich LifeSciences?

What is the difference between Kadcyla and Enhertu?
Kadcyla is also approved as an adjuvant therapy for early breast cancer patients with residual disease. Enhertu has a drug antibody ratio (DAR) of eight, compared to Kadcyla’s mean DAR of 3.5, making Enhertu more cytotoxic.
Is HER2 only on breast cells?
HER2 proteins are receptors on breast cells. Normally, HER2 receptors help control how a healthy breast cell grows, divides, and repairs itself. But in about 10\% to 20\% of breast cancers, the HER2 gene doesn’t work correctly and makes too many copies of itself (known as HER2 gene amplification).
How effective is Enhertu?
Effectiveness for breast cancer In this study: 4.3\% of women taking Enhertu had a complete response to the drug. (A complete response is when tests show no more cancer in your blood.) 56\% of women taking Enhertu had a partial response to the drug.
Is Enhertu approved?
On December 23, 2019, the FDA accelerated the approval of fam-trastuzumab deruxtecan-nxki (Enhertu; Daiichi Sankyo), a HER2-directed antibody and topoisomerase inhibitor conjugate, for the treatment of adults with unresectable or metastatic HER2-positive breast cancer after ≥2 previous anti-HER2–based regimens in the …
Is chemo necessary for HER2-positive?
Trastuzumab and chemotherapy are even recommended for women with very small, HER2-positive breast cancers. Tumors as small as 0.5 cm often warrant such treatment. However, decisions must be individualized based on your own individual risk.
Is Enhertu chemo?
Enhertu® is made up of two cancer-fighting agents: an antibody attached to chemotherapy. Trastuzumab is a monoclonal antibody targeting HER2 receptor on cancer cells. The HER2 gene produces a protein receptor on the cell surface that signals normal cell growth by telling the cell to divide and multiply.
Do you lose your hair with Enhertu?
Hair loss. Hair loss is one of the most common side effects of Enhertu. It’s also a common side effect for many other drugs used to treat breast cancer. In a clinical study, 46\% of people taking Enhertu experienced hair loss.
