Comparison Study of MDX-010 (CTLA-4) Alone and Combined With DTIC in the Treatment of Metastatic Melanoma

A Randomized Study Comparing MDX-010 (CTLA-4) Alone or in Combination With DTIC in the Treatment of Patients With Chemotherapy Naїve Metastatic Melanoma.

The objectives of this study are to determine the safety and activity profile of multiple doses of MDX-010, and to determine the whether the addition of cytotoxic chemotherapy (decarbazine [DTIC]) can augment the effects of MDX-010 in patients with chemotherapy naïve metastatic melanoma with a tolerable toxicity profile.

Inclusion Criteria

• Clinical diagnosis of unresectable metastatic melanoma.
• No prior chemotherapy for melanoma, and no chemotherapy for other malignancies within 5 years and at least 4 weeks since treatment (surgery, radiation, or immunotherapy) for melanoma.

Exclusion Criteria

Patients who exhibit any of the following conditions at screening will not be eligible for admission into the study:

• Any other prior malignancy, except for the following: adequately treated basal or squamous cell skin cancer or superficial bladder cancer, or any other cancer from which the patient has been disease-free for >=5 years.
• Active autoimmune disease.
• Active infection requiring therapy, or chronic active HBV or HCV, or confirmed reactivity with HIV tests.
