About this trial

This is an interventional treatment trial for Cutaneous T Cell Lymphoma focused on measuring Relapsed, Refractory

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age ≥ 18 years
  • Diagnosis of Stage IB-IVB CTCL mycosis fungoides (MF)/Sézary Syndrome (SS)

  • Skin biopsy at the time of or within 6 months prior to study entry
  • Patients must have a total mSWAT (modified Severity Weighted Assessment Tool) score of ≥10 OR have 2 or more measurable tumours of any size. Of this area: there should be at least 1 cutaneous lesion (MF) or a defined area of involved skin (erythrodermic MF or SS) which is an appropriate target for palliative radiotherapy. There should be an area of skin involved by measurable Mycosis Fungoides/SS that will not be irradiated (To assess the abscopal effect of radiotherapy)

  • Have ECOG performance status of 0 or 1
  • Life expectancy of at least 6 months

  • Female patients of childbearing potential must have a negative urine or serum pregnancy test at pre-registration. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
  • Willing to comply with the contraception requirements

  • Diagnosis of prior immunodeficiency or organ-transplant requiring immunosuppressive therapy
  • Current or prior use of immunosuppressive therapy within 7 days prior to start of treatment except the following: intranasal, inhaled, topical steroids or local steroid injections (eg. Intra-articular injection); systemic corticosteroids at physiologic doses (10mg/day or less of prednisolone or equivalent)

  • History of other pulmonary disease such as interstitial lung disease, emphysema or chronic obstructive pulmonary disease
  • Is pregnant or breastfeeding
  • Has a known history of active TB
  • Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial or interfere with the subject's participation for the full duration of the trial or to participate in the trial is not in the patient's best interest, in the opinion of the treating investigator
  • Has known psychiatric or substance abuse disorders that would interfere with the requirements of the trial

5. Study Description

Brief Summary
Trial Subjects (patients), will receive single infusions of pembrolizumab every 3 weeks until disease progression or unacceptable toxicity develops. They will receive radiotherapy at week 12.
Detailed Description
Trial Subjects (patients) who are deemed eligible for the trial will be administered a single infusion of pembrolizumab (200mg) every 3 weeks. At week 12, patients will be planned to start radiotherapy at a dose of 12 Gray (Gy) in 3 fractions which will be given concomitantly with pembrolizumab. Patients who progress on pembrolizumab before week 12 will start radiotherapy as soon as possible after progression. Following completion of radiotherapy, patients will continue receiving pembrolizumab at 3 weekly intervals for a maximum of 2 years until disease progression or unacceptable toxicity develops. Patients on pembrolizumab will be seen every 3 weeks until 2 years after study entry, while Patients who progressed/ stopped pembrolizumab will be seen annually for survival/disease status only. Patients completing 2 years of treatment will then be followed up annually for survival and disease status until the end of trial is declared (2 years after the last patient is registered).
