NCT04930653

Brief Summary

This phase II trial studies the effect of extracorporeal photopheresis (ECP) and mogamulizumab in treating patients with erythrodermic cutaneous T cell lymphoma (CTCL), a type of skin lymphoma. CTCL is a rare type of cancer that begins in the white blood cells called T cells. Erythrodermic is a widespread red rash that may cover most of the body. ECP is a medical treatment that removes blood with a machine, isolates white blood cells and exposes them to ultra violet light, then returns the cells to the body. Mogamulizumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving mogamulizumab with ECP may work together to kill the tumor cells directly (with mogamulizumab) and boost immune response to cancer (with ECP).

Outcome Measures

Primary Outcomes (2)

  • Overall response rate (ORR)

    ORR will be calculated as the proportion of evaluable patients that have confirmed complete response (CR) or partial response (PR), as defined according to global response assessment. Exact 95% confidence intervals will be calculated for these estimates.

    Up to 1 year post treatment

  • Incidence of adverse events

    Toxicity and adverse events will be recorded using the National Cancer Institute Common Terminology Criteria for Adverse Events 5.0 scale. Observed toxicities will be summarized by type, severity, date of onset, and attribution.

    Up to cycle 3 (each cycle = 28 days)

Secondary Outcomes (6)

  • Complete response rate

    Up to 1 year post treatment

  • Time to response

    From initiation of study therapy to the first achievement of CR or PR, assessed up to 1 year

  • Duration of response

    From the first achievement of PR or CR to time of partial disease or death, assessed up to 1 year

  • Progression-free survival

    From initiation of study therapy to the first observation of disease relapse/progression or death from any cause, whichever occurs first, assessed up to 1 year

  • Overall survival

    From initiation of study therapy to death from any cause, assessed up to 1 year

  • +1 more secondary outcomes

Study Arms (1)

Treatment (ECP, mogamulizumab)

EXPERIMENTAL

Patients receive mogamulizumab IV over 60 minutes on days 1, 8, 15, 22, of cycle 1 and days 1 and 15 of subsequent cycles. Beginning in cycle 2, patients also undergo ECP over 3 hours on days 8, 9, 22,and 23. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients achieving CR)/PR after 6 cycles receive up to 6 additional cycles of treatment in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Documented informed consent of the participant and/or legally authorized representative
  • Assent, when appropriate, will be obtained per institutional guideline
  • Agreement to allow the use of archival tissue from diagnostic tumor biopsies
  • If unavailable, exceptions may be granted with study principal investigator (PI) approval
  • Age: \>= 18 years
  • Eastern Cooperative Oncology Group (ECOG) =\< 2
  • Histologically confirmed mycosis fungoides (MF) or Sezary syndrome (SS). Safety lead-in: \>= stage IIB OR \>= stage IB-IIA folliculotropic/transformed MF. Phase 2: \>= stage IB
  • Stage of disease according to Tumor-Node-Metastasis-Blood (TNMB) classification
  • Pathology report must be diagnostic or be consistent with MF/SS criteria
  • SS is defined as meeting T4 plus B2 criteria; where the biopsy of erythrodermic skin may only reveal suggestive but not diagnostic histopathologic features, the diagnosis may be based on either node biopsy or fulfillment of B2 criteria
  • For MF where the histological diagnosis by light microscopic examination is not confirmed, diagnostic criteria that been recommended by the International Society of Cutaneous Lymphomas (ISCL) should be used.
  • Measurable disease per Modified Severity Weighted Assessment Tool (mSWAT) and/or Sezary count
  • Baseline skin biopsy taken within 6 months available for central review submission
  • Without bone marrow involvement: Absolute neutrophil count (ANC) \>= 1,500/mm\^3 (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
