Pembrolizumab in Treating Patients With Relapsed or Refractory Stage IB-IVB Mycosis Fungoides or Sezary Syndrome

Completed · Phase 2

Conditions studied: Recurrent Mycosis Fungoides and Sezary Syndrome, Refractory Mycosis Fungoides and Sezary Syndrome, Stage IB Mycosis Fungoides and Sezary Syndrome AJCC v7, Stage IIA Mycosis Fungoides and Sezary Syndrome AJCC v7, Stage IIB Mycosis Fungoides and Sezary Syndrome AJCC v7, Stage IIIA Mycosis Fungoides and Sezary Syndrome AJCC v7, Stage IIIB Mycosis Fungoides and Sezary Syndrome AJCC v7, Stage IVA Mycosis Fungoides and Sezary Syndrome AJCC v7, Stage IVB Mycosis Fungoides and Sezary Syndrome AJCC v7

In brief

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.

• Performed within 10 days of treatment initiation: Thyroid stimulating hormone (TSH) within institutional limits (ie: normal); if TSH is greater or less than institutional limits patients may participate if their thyroxine (T4) is within normal limits (WNL); patients may be on a stable dose of replacement thyroid medication; dose adjustments are allowed if needed
• Patients must provide tissue from a punch biopsy of the skin at baseline, at the time of a clinical event (at the time of response, progression or appearance of a new lesion) and at the end of treatment; additional punch biopsies every 3 cycles are optional; an archival tissue sample is optional
• Have measurable disease based on modified severity-weighted assessment tool (mSWAT); tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) from the time of the pre-study visit, through the course of the study and for 120 days after the last dose of study medication
• Female patients of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required

• Note: patients with =< grade 2 neuropathy are an exception to this criterion and may qualify for the study
• Note: if patients received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy

• Men and non-pregnant, non-breast-feeding women may be enrolled if they are willing to use 2 methods of birth control or are considered highly unlikely to conceive; highly unlikely to conceive is defined as 1) surgically sterilized, or 2) postmenopausal (a woman who is >= 45 years of age and has not had menses for greater than 1 year will be considered postmenopausal), or 3) not heterosexually active for the duration of the study; the two birth control methods can be barrier method or a barrier method plus a hormonal method to prevent pregnancy; patients should start using birth control from the time of the pre-study visit, through the course of the study and for 120 days after the last dose of study medication; the following are considered adequate barrier methods of contraception: diaphragm, condom (by the partner), copper intrauterine device, sponge, or spermicide; appropriate hormonal contraceptives will include any registered and marketed contraceptive agent that contains an estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or intramuscular agents)
• Patients should be informed that taking the study medication may involve unknown risks to the fetus (unborn baby) if pregnancy were to occur during the study; in order to participate in the study they must adhere to the contraception requirement (described above) for the duration of the study and during the follow-up period; if there is any question that a patient will not reliably comply with the requirements for contraception, that patient should not be entered into the study
• If a patient inadvertently becomes pregnant while on treatment with MK-3475, the patient will immediately be removed from the study; the site will contact the patient at least monthly and document the patient's status until the pregnancy has been completed or terminated; the outcome of the pregnancy will be reported without delay and within 24 hours if the outcome is a serious adverse experience (e.g., death, abortion, congenital anomaly, or other disabling or life-threatening complication to the mother or newborn); the study investigator will make every effort to obtain permission to follow the outcome of the pregnancy and report the condition of the fetus or newborn; if a male patient impregnates his female partner the study personnel at the site must be informed immediately and the pregnancy reported and followed
