Peripheral Artery Disease study: Home Based Exercise vs Nitrate Rich Beetroot Juice
Official title Improving Mobility After Revascularization in Peripheral Artery Disease
ClinicalTrials.gov ID: NCT06686121
What this study is testing
What is Nitrate Rich Beetroot Juice?
an investigational dietary supplement being studied as a potential treatment for peripheral artery disease is designed to increase nitric oxide levels, which may help improve blood flow and walking performance
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see if doing exercise at home and drinking beetroot juice can help people walk farther after they have had leg artery surgery for peripheral artery disease.
- Who it's for
- Adults who have had successful lower‑leg artery surgery for disabling peripheral artery disease within the past three months.
- What's involved
- Participants will be randomly assigned to home‑based walking exercises, beetroot juice (or a placebo drink), both, or neither, and will have their walking distance measured and other routine check‑ups.
- Time commitment
- The trial lasts about six months with visits for randomization, follow‑up assessments, and the six‑minute walk test.
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.

- Currently taking sildenafil, tadalafil, or related drugs.
- Unwilling to accept randomization into either group (home-based exercise or attention control)
- Currently consuming beetroot juice, oral nitrate or nitrite, or a beetroot supplement and/or unwilling to avoid beetroot juice during the study.
- History of kidney stones that requires minimized intake of oxalate. Potential participants who need to minimize oxalate intake will be excluded from the trial.
- Baseline blood pressure \<100/45.
- Wheelchair confinement or requiring a walker to ambulate
- Walking is limited by a condition other than PAD
- Current foot ulcer

- Major medical illness including lung disease requiring oxygen, Parkinson's disease, or a life-threatening illness with life expectancy less than six months.
- Allergy to beetroot juice
- Currently consuming one cup or more of beets daily. Participants will be asked to decrease beet consumption to less than one cup of beets per day for 14 days before baseline testing and throughout the clinical trial.
- Participation in or completion of a clinical trial in the previous three months, using investigator discretion for trials that may not impact study participation or outcome measures of the IMPACT PAD Trial.
- Visual impairment that limits walking ability.
- Unable to communicate in English, unless the participant communicates in Spanish and is enrolled at a site that can deliver the intervention in Spanish.
- Using a mouthwash containing chlorhexidine or cetylpyridinium chloride or a mouthwash determined to be bactericidal and unwilling to discontinue.
- Planning to begin a supervised treadmill exercise program in the next 12 months.
- Heart attack or stroke in previous three months prior to baseline testing.
- An eGFR value \ 5.0.
- In addition to the above criteria, investigator discretion will be used to determine if the trial is unsafe or not a good fit for the potential participant.
