This phase II trial studies how well pembrolizumab works in treating patients with stage IB-IVB mycosis fungoides or Sezary syndrome that has returned after a period of improvement or has not responded to at least one type of treatment. Monoclonal antibodies, such as pembrolizumab, may block cancer growth in different ways by targeting certain cells.

Primary Outcome Measures:
  • Objective response rate (ORR), defined as a confirmed partial response (PR) or CR using global assessment standard response criteria for MF and SS [ Time Frame: Up to 5 years ]
    A generalized linear model for the objective response rate will use a binomial error distribution. The model will include as covariates all available baseline predictors of the missing outcomes.

Secondary Outcome Measures:
  • DOR [ Time Frame: The time interval between the date of first response (CR/PR) and the date of progression as assessed by standard MF and SS response criteria, assessed up to 5 years ]
    Will be estimated using the Kaplan-Meier method.

  • Incidence of adverse events graded using the Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to 90 days after last dose of trial treatment ]
    Adverse experiences will be summarized as counts and frequencies by toxicity grade. Summary statistics (median and range) for time to onset of first drug-related toxicity will be provided.

  • OS [ Time Frame: The time from randomization to death due to any cause, assessed up to 5 years ]
    Will be estimated using the Kaplan-Meier method.

  • PFS [ Time Frame: The time from allocation to the first documented disease progression or death due to any cause, whichever occurs first, assessed up to 5 years ]
    Will be estimated using the Kaplan-Meier method.

Estimated Enrollment: 24
Study Start Date: October 2014

Detailed Description:


I. To assess the response rate of MK-3475 (pembrolizumab) in subjects with relapsed/refractory mycosis fungoides/Sezary syndrome (MF/SS).


I. To explore the clinical activity of MK-3475 in subjects with relapsed/refractory MF and SS with respect to the following endpoints: duration of response (DOR); progression-free survival (PFS); overall survival (OS).


Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Courses repeat every 3 weeks for up to 2 years (6 months for patients achieving complete response [CR]) in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days and then every 12 weeks.
