Phase I Trial of O6 Benzylguanine and BCNU in Cutaneous T-cell Lymphoma (NCT00003613)

This phase I trial is studying the side effects and best dose of carmustine given together with O(6)-benzylguanine in treating patients with stage I or stage II cutaneous T-cell lymphoma that has not responded to previous treatment. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells
  • Drug: O6-benzylguanine
    Given IV
    • BG
  • Drug: carmustine
    Given topically
    • BCNU
    • BiCNU
    • bis-chloronitrosourea
  • Other: laboratory biomarker analysis
    Correlative studies
    Ages eligible for Study
    19 Years and older
    Genders eligible for Study
    Accepts Healthy Volunteers
    Inclusion Criteria:
    • Histologically confirmed CTCL, stages IA-IIA
    • Performance status ECOG grade 0, 1, or 2
    • Patients must have recovered from toxicity of prior treatment and have received no CTCL therapy other than emoliation for at least 4 weeks
    • Patients must have signed a consent form indicating the investigational nature of the treatment and its potential side effects
    • WBC > 4,000/ul
    • ANC > 2,000/ul

    • Calcium and electrolytes normal
    • Glucose-controlled (diet and insulin) diabetes is permitted
    • DLCO > 80% normal with the exception of patients who demonstrate clinically normal lung function based on history, physical examination, and chest x-ray as interpreted by the principal investigator
    • Only those patients with biopsiable tumor and willing to undergo several biopsies will be eligible
    • Must have failed 1 conventional treatment other than topical corticosteroids; this includes UVB, PUVA, topical mechlorethamine, electron beam, photopheresis, chemotherapy and immuno-modulatory agents such as cytokines
    Exclusion Criteria:
    • Patients with a prior treatment with a nitrosourea
    • Patients with known central nervous system involvement or primary CNS malignancies will be ineligible
    • Patients with performance status ECOG grade 3 or 4
    • Pregnant women, women who are breast feeding infants, or women with reproductive potential not practicing adequate contraception, because of potential toxicity to the fetus or infant
    • Patients with active infection
    • Patients with pulmonary disease as determined by history, physical examination, chest X-ray or pulse oximetry
    • CTCL patients with stage IIB-IVB disease

    I. To determine the kinetics of AGT depletion in CTCL skin lesions. II. To determine the toxicity of low dose BCNU plus O6BG.

    OUTLINE: This is a dose-escalation study of carmustine.

    Patients receive O6-benzylguanine IV over 1 hour followed by topical carmustine once every 2 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.

    Cohorts of 3-6 patients receive escalating doses of carmustine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

    Patients are followed for 6 weeks.
