Study information

Scientific title

A phase II, multicentre, non-randomised, open-label, single arm trial of the efficacy of Gemcitabine and Bexarotene in patients who have developed progressive cutaneous T-cell lymphoma (CTCL)



Study hypothesis

This is a phase II, multicentre, non-randomised, open-label, single arm trial of Gemcitabine and Bexarotene for the treatment of cutaneous T-cell lymphoma (CTCL) in patients who have developed progressive disease after receiving, or have been refractory to, standard skin-directed therapy and at least one prior systemic therapy. The study aims to to evaluate the efficacy of Gemcitabine and Bexarotene as a combination therapy in patients with CTCL in terms of the rate of objective disease response and its duration, and to determine whether the combination has sufficient biological activity in CTCL to warrant more extensive investigation. This is a "two stage" study where 35 patients will be treated initially and if the response criteria are met, further 49 to a total of 84 patients will be treated on the study.

Topic: National Cancer Research Network; Subtopic: Lymphoma; Disease: Lymphoma (non-Hodgkin's)


Prophylactic fenofibrate; patients start prophylactic Fenofibrate 160 - 200 mg daily 7 days before chemotherapy. Initial chemotherapy: 4 x 21 day cycles:
Gemcitabine 1000 mg/m^2 intravenous (iv) days 1 and 8
Bexarotene 300 mg/m^2 orally (po) daily*
* Bexarotene given at a reduced dose of 150 mg/m^2 for weeks 1 and 2 of cycle 1 and, if tolerated, increased to 300 mg/m^2 as per British Dermatology Society guidelines

In patients responding after 4 cycles of Gemcitabine + Bexarotene:
Bexarotene maintenance 300 mg/m^2 daily until disease progression or patient

Study Entry: Registration only
Details: As this is a single arm study, all patients registered will recieve the same treatment.
