Study to Assess Efficacy of Risedronate in Preventing Bone Loss in Postmenopausal Women Treated for Breast Cancer
Randomized, Double-blinded, Placebo Controlled Study to Assess Efficacy of Oral 35 mg Per Week Risedronate in Preventing Bone Loss in Postmenopausal Women With Aromatase Inhibitor Therapy for Breast Cancer.

Aromatase inhibitor therapy is in France the adjuvant reference treatment for postmenopausal women with early-stage breast cancer. This treatment induces bone loss and a higher risk of fractures.

This study aimed to document the effect of bisphosphonate therapy in preventing bone loss and osteoporotic fractures in postmenopausal women with aromatase inhibitor treatment for breast cancer

Interventional
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
  • Breast Cancer
  • Menopause
  • Osteopenia
  • Drug: Risedronate
    35mg oral risedronate once per week for 24 months
  • Drug: Placebo
    Placebo 35 mg once a week for 24 months
  • Placebo Comparator: 2

    Patients receive placebo 35 mg once a week plus a calcium and vitamin D supplementation.

    Measure of bone density, bone markers, clinical examination and questionnaire regarding fractures will be assessed at 12 and 24 months of treatment

    Intervention: Drug: Placebo
  • Active Comparator: 1

    Patients receive risedronate 35 mg once a week plus a calcium and vitamin D supplementation.

    Measure of bone density, bone markers, clinical examination and questionnaire regarding fractures will be assessed at 12 and 24 months of treatment

    Intervention: Drug: Risedronate
