CP-675,206 is a fully human monoclonal antibody (mAb). It binds to the CTLA4 molecule, which is expressed on the surface of activated T lymphocytes. CP-675,206 is thought to stimulate patients' immune systems to attack their tumors. CP-675,206 is not expected to have a direct effect on tumor cells. CP-675,206 been shown to induce durable tumor responses in patients with metastatic melanoma in Phase 1 and Phase 2 clinical studies.

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To assess the anti-tumor efficacy, as determined by objective response rate, of intravenous CP-675,206 administered at a dose of 15 mg/kg every 90 days to patients with relapsed or refractory advanced melanoma [ Time Frame: Tumor response is assessed every 2-3 months until disease progression ]

Secondary Outcome Measures:
  • Safety [ Time Frame: At every scheduled visit as specified per protocol for a maximum of 2 years from first dose of drug ]
  • Pharmaco Kinetic [ Time Frame: At every scheduled visit as specified per protocol for a maximum of 2 years from first dose of drug ]
  • Survival [ Time Frame: At every scheduled visit as specified per protocol for a maximum of 2 years from first dose of drug ]
  • Health-related QoL [ Time Frame: At every scheduled visit as specified per protocol for a maximum of 2 years from first dose of drug ]
