Официальное название

A Phase II Randomized Study of Solifenacin Compared to Clonidine for Reducing Hot Flashes Among Breast Cancer Patients Receiving Adjuvant Hormonal Therapy

Обзор

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).

Подробное описание

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.

Вмешательства

  • Препарат solifenacin
    oral solifenacin 5.0 mg daily for 3 weeks
  • Препарат Clonidine
    oral clonidine 0.1 mg daily for 3 weeks

Первичные конечные точки

  • Efficacy: hot flash composite and frequency scores (daily diary) [Срок оценки: from baseline to end of treatment (3 weeks)]
  • Safety: number of clinician-rated adverse events [Срок оценки: from consent until end of study (approximately 9 weeks)]
Вторичные конечные точки (3)
  • daily functioning (Hot Flash-Related Daily Interference score) [Срок оценки: from baseline to end of treatment (3 weeks)]
  • sleep (Insomnia Severity Index) [Срок оценки: from baseline to end of treatment (3 weeks)]
  • quality of life (Illness Cognition Questionnaire, SF-12) [Срок оценки: from baseline to end of treatment (3 weeks)]
