Randomized Anastrozole Exercise Trial

Phase 3

• Conditions: Musculoskeletal Symptoms
• Interventions: Other: Exercise; Other: Supportive Care

• Registration Number: NCT00519883
• Lead Sponsor: British Columbia Cancer Agency

Brief Summary

This is a randomized, phase III trial of a 12 week exercise program, followed by a 36 week voluntary, self-directed exercise program (total 48 weeks) compared to standard supportive care. The purpose of the trial is to determine whether the exercise program is better than standard supportive care to decrease the muscle and joint aches (musculoskeletal symptoms) that result from aromatase inhibitors.

Hypothesis An exercise program that includes stretching, strengthening and aerobic components may improve physical quality of life among women with musculoskeletal symptoms who are taking aromatase inhibitors.

Group	Intervention	Description
B	Exercise	Arm B: Exercise Intervention
A	Supportive Care	Arm A: Standard Supportive Care (no supervised exercise)

Primary Outcome Measures

Name	Time	Method
The primary endpoint is the mean SF36 physical component summary (PCS) score for subjects in each study Arm after 12 weeks.

Secondary Outcome Measures

Name	Time	Method
Hot Flashes: A hot flash scale will be given to subjects to complete at each scheduled follow up visit (baseline, week 4,8,12,24,36,48). Severity and frequency of hot flashes will be compared between the exercise and control groups at each time point
Difference in musculoskeletal symptoms as measured by VAS and NCIC-CTC toxicity criteria.
Global QOL: As measured by SF36 and VAS composite scores at each scheduled follow up visit (Baseline, weeks 4,8,12,24,36,48). See Appendix B for instruments.
Arm Circumferences: Arm circumferences will be measured for all subjects on both arms as described in Appendix D at each study follow up visit except weeks 4, 8, and 36.
Bone Mineral Density.
Body Mass Weight, in kilograms, will be recorded for all subjects at baseline and at weeks 4,8,12,24,36, and 48 week visits.
