Evaluating creatine supplementation for breast cancer survivors

An Open-label Randomized Trial of Exercise ± Creatine Supplementation to Augment the Adaptations of Exercise Training in Cancer Survivors

Not applicable Interventional The University of Texas Medical Branch, Galveston · NCT06395506

This study is testing if taking creatine can help breast cancer survivors improve their strength, endurance, and body composition after finishing chemotherapy.

What this trial studies

This study aims to assess the impact of creatine supplementation on strength, endurance, and body composition in breast cancer survivors who have recently completed chemotherapy. Participants will engage in virtual exercise sessions while their responses to creatine will be compared to healthy women of similar age. The primary focus is on how creatine can enhance physical function and recovery in this population.

Who should consider this trial

Good fit: Ideal candidates are breast cancer survivors aged 18-75 who have completed chemotherapy within the last six months.

Not a fit: Patients currently undergoing chemotherapy or with significant physical limitations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the physical recovery and quality of life for breast cancer survivors.

How similar studies have performed: While the specific combination of creatine supplementation and exercise in breast cancer survivors is novel, similar studies have shown positive outcomes with exercise interventions in cancer recovery.
