Expected Enrollment

A total of 408 patients (136 per arm) will be accrued for this study within 18 months.

Outline

This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to participating center and duration of hot flash symptoms (less than 9 months vs 9 or more months). Patients are randomized to 1 of 3 arms.

• Arm I: Patients receive oral placebo 3 times a day.
• Arm II: Patients receive oral gabapentin at a low dose 3 times a day.
• Arm III: Patients receive oral gabapentin as in arm II for 3 days and then at a high dose 3 times a day.

Treatment on all arms continues for 8 weeks in the absence of unacceptable toxicity. After week 8, patients may receive open-label gabapentin at the discretion of their physicians.

Hot flashes are assessed at baseline and then during weeks 3 and 7 of the study.

Quality of life, anxiety, and depression are assessed at baseline and then at weeks 4 and 8.

Patients are followed at week 12.
