Study Details

Study Description

Brief Summary

This pilot trial studies the side effects and how well imiquimod and pembrolizumab work in treating patients with stage IIIB-IV melanoma. Imiquimod may stimulate the immune system. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Giving imiquimod and pembrolizumab may work better at treating melanoma.

Condition or Disease Intervention/Treatment Phase
  • Drug: Imiquimod
  • Other: Laboratory Biomarker Analysis
  • Biological: Pembrolizumab
Early Phase 1

Detailed Description

PRIMARY OBJECTIVES:
  1. To gain preliminary data of the anti-tumor activity and safety profile of the combination of imiquimod and pembrolizumab in patients with unresectable cutaneous melanoma.
SECONDARY OBJECTIVES:
  1. To compare and contrast (in a hypothesis generating manner) the biomarker profiles of patients who have a confirmed complete response (CR) or partial response (PR) by Response Evaluation Criteria in Solid Tumors (RECIST) criteria with patients who do not.
OUTLINE:

Patients receive pembrolizumab intravenously (IV) on day 1 and apply imiquimod cutaneously on days 1-5 (Monday - Friday). Courses repeat every 21 days for up to 2 years (approximately 35 courses) in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 12 weeks for 2 years.

  • Outcome Measures

    Primary Outcome Measures

    1. Duration of response [From registration to disease progression, assessed up to 2 years]

      Will be estimated using the Kaplan-Meier method.

    2. Incidence of adverse events graded using Common Terminology Criteria for Adverse Events version 4.0 [Up to 2 years]

      For each type of toxicity reported, the proportion of patients experiencing a severe level of that toxicity will be determined.

    3. Overall survival [From registration to death due to any cause, assessed up to 2 years]

      Will be estimated using the Kaplan-Meier method.

    4. Progression free survival [From registration to documentation of first disease progression or death due to any cause, assessed up to 2 years]

      Will be estimated using the Kaplan-Meier method.

    5. Tumor response rate defined as percentage of patients whose objective disease status meets the criteria for Response Evaluation Criteria in Solid Tumors (RECIST) criteria for partial or complete response on two consecutive disease evaluations [Up to 2 years]

      If there are no tumor responses documented among these 10 patients, then upper bound of a one-sided 95% confidence interval for the tumor response rate would be 25.9%.

    Secondary Outcome Measures

    1. Biomarker changes during treatment [Baseline up to 12 weeks]

      For each patient and each biomarker, a times-series plot of biomarker value will be constructed. These graphs will be visually examined for trends within and between the group of patients whose tumor responded to treatment and the group of patients whose tumor did not respond to treatment. Will include assessing total tumor RNA through RNA seq and PDL1 expression through the use of immunohistochemistry.
