Lenalidomide Maintenance Post-debulking in Advanced CTCL

• Status: Terminated
• Trial end date: 2013-09-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Observation is watching a patient's condition but not giving treatment unless symptoms appear or change. Lenalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. It is not yet known whether observation or lenalidomide is more effective in treating patients who are in complete or partial response after receiving previous gemcitabine hydrochloride or doxorubicin hydrochloride liposome for cutaneous T-cell lymphoma or mycosis fungoides/Sézary syndrome.

PURPOSE: This randomized phase III trial is studying observation to see how well it works compared with lenalidomide in treating patients who are in complete or partial response after receiving previous gemcitabine hydrochloride or doxorubicin hydrochloride liposome for stage IIB, stage III, or stage IV cutaneous T-cell lymphoma or stage IIB, stage III, or stage IV mycosis fungoides/Sézary syndrome.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

• Treatments: Lenalidomide; Thalidomide

Criteria

DISEASE CHARACTERISTICS:

• Diagnoses of advanced T-cell cutaneous lymphoma or mycosis fungoides/Sézary syndrome

• Stage IIB-IV disease

• Achieved complete or partial response after undergoing prior debulking therapy with 1 of the following recommended* regimens with or without radiotherapy**:

• Gemcitabine hydrochloride IV over 30 minutes on days 1, 8, and 15 of a 28-day course at a dose of 1,000 to 1,200 mg/m² for a total of four courses

• Pegylated liposomal doxorubicin hydrochloride IV over 1 hour on days 1 and 15 of a 28-day course at a dose of 20 mg/m² for a total of four courses NOTE: *These recommended regimens can be altered according to local institutional policies. In case of drug intolerance, the study regimen can be switched from one regimen to the other.

NOTE: **Local low-dose/energy-ionizing radiation therapy allowed as part of the debulking process to treat lesions that do not respond after 3 courses of debulking chemotherapy.

• Sézary cell burden must be decreased by at least 50% after debulking in patients with Sézary syndrome

• No prior splenectomy or splenic irradiation

• No concurrent topical corticosteroids

• Concurrent systemic corticosteroids allowed for treatment of tumor flare reactions

• No radiation or drug-based therapy (including steroids) between registration and randomization
