About this trial

This is an interventional treatment trial for Lymphoma focused on measuring recurrent mycosis fungoides/Sezary syndrome, recurrent cutaneous T-cell non-Hodgkin lymphoma

Eligibility Criteria

18 Years - 120 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

DISEASE CHARACTERISTICS:

  • Histologically confirmed cutaneous T-cell non-Hodgkin lymphoma (CTCL)
  • Relapsed or refractory disease, meeting 1 of the following criteria:

    • Progression of disease following 2 prior chemotherapies
    • Failure to respond to the second prior chemotherapy
  • Measurable disease

PATIENT CHARACTERISTICS:

  • ECOG performance status 0-2
  • Life expectancy > 3 months
  • Serum creatinine < 1.5 times upper limit of normal (ULN)
  • Serum AST/ALT < 2.5 times ULN
  • Total bilirubin ≤ 2.0 mg/dL (< 3.0 mg/dL in patients with Gilbert syndrome)
  • WBC count ≥ 3,000/mm³
  • Platelet count ≥ 100,000/mm³
  • Serum albumin > 2.5 g/dL
  • LVEF ≥ 45% by 2-D ECHO or MUGA scan
  • Human antimurine antibody < 1 μg/mL
  • Patients with a history of electrocardiogram abnormalities, symptoms of cardiac ischemia, or arrhythmias must have a normal cardiac stress test (i.e., stress thallium, stress MUGA, dobutamine echocardiogram, or other stress test)
  • Must be willing to undergo venipuncture and central line placement
  • Not pregnant or nursing
  • Negative pregnancy test
  • Fertile patients must use effective contraception
  • No HBV surface antigen, HCV, or HIV antibody positivity
  • No autoimmune disease or immunodeficiency (i.e., HIV)
  • No history of uncontrolled concurrent illness including, but not limited to, any of the following:

    • Ongoing or active infection
    • Ongoing or active cardiac disease (i.e., congestive heart failure, unstable angina pectoris, or cardiac arrhythmia)
    • Psychiatric illness and/or social situation that would preclude study compliance
  • No other malignancies except treated basal cell or squamous cell carcinoma of the skin, or treated carcinoma in situ of the cervix

PRIOR CONCURRENT THERAPY:

  • See Disease Characteristics
  • More than 3 weeks since prior systemic therapy for CTCL
  • More than 6 months since prior chronic steroid therapy or chronic anti-coagulation therapy
  • No prior therapy with anti-CD25 immunotoxin IMTOX25 and/or Ontak
  • No other concurrent cancer chemotherapy, experimental therapy, investigational agent, or immunomodulating agent (including steroids)

Brief Summary
RATIONALE: Immunotoxins, such as RFT5-dgA immunotoxin (also called anti-CD25 immunotoxin IMTOX25), can find certain cancer cells and kill them without harming normal cells. PURPOSE: This phase II trial is studying the side effects of anti-CD25 immunotoxin IMTOX25 and how well it works in treating patients with relapsed or refractory cutaneous T-cell non-Hodgkin lymphoma.
Detailed Description
OBJECTIVES: Primary Determine the response rate of patients with relapsed or refractory cutaneous T-cell non-Hodgkin lymphoma (CTCL) following treatment with RFT5-dgA immunotoxin (anti-CD25 immunotoxin IMTOX25) . Secondary Determine whether responses correlate with the level of CD25+ expression on the CTCL tumor cells. Determine whether changes in the pre-treatment and the post-treatment levels of CD4+CD25+ Treg cells correlate with responses. OUTLINE: Patients receive anti-CD25 immunotoxin IMTOX25 IV over 4 hours on days 1, 3, and 5. Treatment repeats every 6 weeks for 6 courses in the absence of disease progression or unacceptable toxicity. Tissue and blood samples are collected at baseline, and during study for CD25+ expression by fluorescent-activated cell sorter analysis, immunohistochemistry. After completion of study therapy, patients are followed every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter.
