Tremelimumab and CP-870,893 in Patients With Metastatic Melanoma

Phase 1

Completed

• Conditions: Recurrent Melanoma; Stage IV Melanoma
• Interventions: Biological: CD40 agonist monoclonal antibody CP-870,893; Biological: tremelimumab; Other: laboratory biomarker analysis

• Registration Number: NCT01103635
• Lead Sponsor: Abramson Cancer Center at Penn Medicine

Brief Summary

RATIONALE: Monoclonal antibodies, such as tremelimumab and CD40 agonist monoclonal antibody CP-870,893, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry cancer-killing substances to them. Giving tremelimumab together with CD 40 agonist monoclonal antibody CP-870, 893 may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of giving tremelimumab together with CD40 agonist monoclonal antibody CP-870,893 in treating patients with metastatic melanoma.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess the safety, dose-limiting toxicities and maximum tolerated doses of tremelimumab (administered intravenously every 12 weeks) and CP- 870,893 (administered intravenously every 3 weeks).

SECONDARY OBJECTIVES:

I To seek preliminary evidence of anti-tumor efficacy of the combination of tremelimumab and CP-870,893, including objective response rate at MTD.

II. To determine the immune pharmacodynamic changes associated with the administration of the combination of tremelimumab and CP-870,893.

OUTLINE: Patients receive tremelimumab IV over 1 hour on day 1 and CD40 agonist monoclonal antibody CP-870,893 IV over 30 minutes on days 2, 22, 43, and 64. Treatment repeats every 12 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed for 4 weeks.

Primary Outcome Measures

Name	Time	Method
Response	2 years	Clinical response will be scored using RECIST criteria. Patients who do not complete a clinical response evaluation will be scored as unevaluable. The objective response rate is defined as the proportion of patients treated at the MTD who achieve either a complete or partial response. Unevaluable patients are included in the calculation of the objective response rate.
Toxicity as assessed by CTCAE v3.0	2 years	Toxicities which occur during later cycles will be monitored and described separately. The MTD is defined as the dose level at which 0-1/6 patients experience DLT in the first 12 week cycle and at least 2/3 or 2/6 patients treated at the next higher dose level (unless MTD is level 4) experience DLT in the first 12 week cycle.
Immunological outcomes (analysis of antigen presenting cell activation, antigen-specific T cells, and tumor-specific T cells)	2 years	Analysis of antigen presenting cell (APC) activation, 2) analysis of antigen-specific T cells and 3) tumor-specific T cells, as described in Section 7.2. For T cell response analyses, overall immune response is defined as \>2 fold pre-treatment/post-treatment increase in any of the key T cell parameters.
