Summary
Hot flashes present a considerable problem for many breast cancer patients; these symptoms
may be intensified by hormonal therapies, such as aromatase inhibitors or tamoxifen. This
study examines the value of solifenacin (a muscarinic acetylcholine receptor antagonist) in
reducing hot flashes, compared with clonidine (a medication often used for treating hot
flashes).
Clinical Details
Official title: A Phase II Randomized Study of Solifenacin Compared to Clonidine for Reducing Hot Flashes Among Breast Cancer Patients Receiving Adjuvant Hormonal Therapy
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Supportive Care
Primary outcome: hot flash composite and frequency scores (daily diary)number of clinician-rated adverse events
Secondary outcome: daily functioning (Hot Flash-Related Daily Interference score)sleep (Insomnia Severity Index) quality of life (Illness Cognition Questionnaire, SF-12)
Detailed description:
There has been considerable interest in developing new treatment strategies for managing hot
flashes among women with breast cancer, in view of the limitations associated with currently
available treatments. This randomized study evaluates the safety and efficacy of 3 weeks of
solifenacin compared to 3 weeks of clonidine, for women receiving adjuvant hormonal therapy
(aromatase inhibitors or tamoxifen) for breast cancer.
