Brief summary

The purpose of this study is to find out whether the combination of pembrolizumab and gemcitabine is an effective treatment for mycosis fungoides and Sézary syndrome.

Interventions

DRUGGemcitabine

Participants will receive gemcitabine 1000 mg/m2 on days 1 and 8 on 21-days cycles for up to 6 cycles

DRUGPembrolizumab

Pembrolizumab 200 mg will be introduced with cycle 2 and will be given on day 1 of each 21-day cycle for up to 35 cycles

Inclusion criteria

* Confirmed mycosis fungoides/Sezary syndrome, disease stage IB (defined as patches, plaque, or papules that involve 10% of the skin surface viscera) or higher. * Age ≥ 18 years. * ECOG Performance Score between 0-1 * Receipt of at least one prior systemic therapy for MF/SS. * Previous systemic anti-cancer therapy must have been discontinued at least 2 weeks prior to treatment. See section 6.2 Subject

Exclusion criteria

for guidelines regarding adjuvant and maintenance therapy for prior malignancy. * Topical or systemic steroids (equivalent to ≤ 10 mg/day of prednisone) may be considered if dose has been constant and discontinuation may lead to rebound flare in disease, adrenal insufficiency, and/or unnecessary suffering. * Prior therapy with gemcitabine allowed. * Refer to Table 1 for laboratory inclusion criteria. * The participant (or legally acceptable representative if applicable) provides written informed consent for the trial. * A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: * Not a woman of childbearing potential (WOCBP) as defined in Appendix C * A WOCBP who agrees to follow the contraceptive guidance in Appendix C * A male participant must agree to use a contraception as detailed in Appendix C of this protocol from screening and through 6 months after the last dose of gemcitabine or 120 days after the last dose of pembrolizumab (whichever is later) and refrain from donating sperm during this period. Table 1: Laboratory Parameters for Inclusion Criteria System : Laboratory Value Hematological Absolute neutrophil count (ANC): ≥ 1500/μL Platelets: ≥ 100 000/μL Hemoglobin: ≥ 9.0 g/dL or ≥ 5.6 mmol/L\^a Renal Creatinine OR Measured or calculated\^b creatinine clearance (GFR can also be used in place of creatinine or CrCl): ≤ 1.5 × ULN OR ≥ 30 mL/min for participant with creatinine levels \> 1.5 × institutional ULN Hepatic Total bilirubin: ≤ 1.5 ×ULN OR direct bilirubin ≤ ULN for participants with total bilirubin levels \>1.5 × ULN AST (SGOT) and ALT (SGPT): ≤ 2.5 × ULN (≤ 5 × ULN for participants with liver metastases) Coagulation International normalized ratio (INR) OR prothrombin time (PT) Activated partial thromboplastin time (aPTT): ≤ 1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants ALT (SGPT)=alanine aminotransferase (serum glutamic pyruvic transaminase); AST (SGOT)=aspartate aminotransferase (serum glutamic oxaloacetic transaminase); GFR=glomerular filtration rate; ULN=upper limit of normal. * a: Criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks. * b: Creatinine clearance (CrCl) should be calculated per institutional standard. Note: This table includes eligibility-defining laboratory value requirements for treatment; laboratory value requirements should be adapted according to local regulations and guidelines for the administration of specific chemotherapies.
