Ensituximab

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

**Definition:** A chimeric monoclonal antibody against human colorectal and pancreatic carcinoma-associated antigens (CPAAs) with potential immunomodulating and anti-tumor activities. Anti-CPAA monoclonal antibody NPC-1C binds to CPAAs, which may activate the immune system to exert a cytotoxic T-lymphocyte (CTL) response and an antibody-dependent cellular cytotoxicity (ADCC) response against CPAA-expressing tumor cells. CPAAs, cell surface proteins, are upregulated on colon and pancreatic tumor cells. NPC-1C contains the variable region of the heavy and light chain of murine NPC-1 and linked in-frame to constant regions of a human IgG1 isotype.

**Synonyms:** - Anti-CPAA Monoclonal Antibody NPC-1C - Anti-Colorectal and Pancreatic Carcinoma-Associated Antigen Monoclonal Antibody NPC-1C - ENSITUXIMAB - NPC-1C
