Control of Vasomotor Symptoms in Women Treated for Breast Cancer

RATIONALE: Gabapentin may be effective for the control of hot flashes. It is not yet known
if gabapentin is effective in treating hot flashes.

PURPOSE: Randomized clinical trial to study the effectiveness of gabapentin in controlling
hot flashes in women who have breast cancer.

OBJECTIVES:

- Compare the effectiveness and side effects of 2 different doses of gabapentin vs
placebo for the control of hot flashes and other vasomotor symptoms in women with
breast cancer.

- Compare quality of life, anxiety, and depression in patients treated with these
regimens.

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.

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