Walking away from prostate cancer: 36 men test exercise as therapy
NCT ID NCT05751434
First seen Jun 27, 2026 · Last updated Jul 31, 2026 · Updated 2 times
Summary
This phase 2 trial tests whether a personalized walking program can slow the progression of localized prostate cancer in men who are on active surveillance (monitoring instead of immediate treatment). The 36 participants will exercise up to 5 times per week for 225-300 minutes total, until their next routine biopsy (about 6-12 months later). Researchers will compare changes in tumor markers between the exercise group and a usual-care group to see if exercise makes the cancer less aggressive.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- exercise therapy
- What this could lead to
- If it works, this could show that a structured walking program helps keep localized prostate cancer from becoming more aggressive, potentially offering a non-drug way to manage the disease.
- What could go wrong
- This is a small, early-phase trial with only 36 men, so results may not apply to everyone. Exercise may not change cancer markers, and the study does not test long-term outcomes like preventing spread.

Inclusion Criteria: * Age ≥ 18 * Men with histologically confirmed localized prostate cancer undergoing active surveillance. * Inactive, defined as not meeting the national exercise guidelines for cancer patients (\<150 minutes/week of moderate or vigorous exercise)43 as assessed by remote activity and heart rate tracking for a 7-day period prior to study entry (general physical activity screening assessment via smart watch). * Screening clearance by an MSK Exercise Physiologist (i.e., review of ECG) * BMI \<40 kg/m\^2 * Cleared for exercise participation as per pre-screening clearance via the Physical Activity Readiness Questionnaire (PAR-Q+) (Appendix B) Exclusion Criteria: * Enrollment in any other program that may alter the impact of exercise on tumor outcomes (e.g., weight loss program) * Any neoadjuvant anticancer treatment of any kind for prostate cancer in the last 5 years * Any history of systemic anticancer therapy in the last 15 years * Distant metastatic malignancy of any kind * Any other condition or intercurrent illness that, in the opinion of the investigator, makes the subject a poor candidate for study participation
