Ipilimumab
Monoclonal AntibodyIpilimumab is indicated for the treatment of unresectable or metastatic melanoma in adults. It is also used to reduce the risk of the deadly skin cancer returning after surgery.
Ipilimumab is a fully human IgG1κ antibody that binds to CTLA-4 (cytotoxic T lymphocyte-associated antigen 4), a molecule on T-cells that is indicated for unresectable or metastatic melanoma. The absence or presence of CTLA-4 can augment or suppress the immune system's T-cell response in fighting disease. Ipilimumab is designed to block the activity of CTLA-4, thereby sustaining an active immune response in its attack on cancer cells. The proposed mechanism of action is indirect, and may be through T-cell - mediated anti-tumor immune responses.
