CTP-37

**Semantic type:** Amino Acid, Peptide, or Protein|Immunologic Factor

**Definition:** A synthetic peptide vaccine consisting of the carboxy terminal peptide (CTP) of human beta chorionic gonadotropin (beta-hCG). Vaccination with CTP-37 may stimulate the host immune system to produce antibodies against beta-HCG, leading to a decrease in the proliferation of tumor cells that overexpress beta-HCG. (NCI04)
