Overview
ECUM-RUN is a randomized, double-blind, placebo-controlled phase 3 trial evaluating whether a 30-day oral supplementation with curcumin, ginger, and piperine (9-5-1 formulation) reduces exercise-induced joint pain and inflammatory markers in 82 ultra-trail runners competing in the Diagonale des Fous (175 km). The primary endpoint is the change in knee pain (VAS score) between end of supplementation and race finish, compared between intervention and placebo groups.
Interventions
- Dietary supplement 9-5-1
The investigational intervention is an oral food-supplement capsule combining curcumin, ginger, and piperine in a proprietary "9-5-1" ratio (curcuma extract : ginger extract : black pepper/piperine extract), administered as 4 capsules per day for 30 consecutive days prior to the race. - Dietary supplement Placebo
Capsule excipients are maltodextrin and hydroxypropylmethylcellulose (HPMC), allowing an identical-appearing placebo for double-blind conditions.
Primary outcome measures
- Change in Knee Pain Intensity from End of Supplementation to Race Finish (Visual Analog Scale) [Time frame: From Day 30 (T1, end of the 30-day supplementation period) to race finish or withdrawal (T2) - up to approximately 60 hours later, corresponding to the maximum allowed race duration.]
Secondary outcome measures (11)
- Kinetics of Joint Pain Across the Study Period (Ankles, Knees, Hips) [Time frame: (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Change in Joint Range of Motion (Ankles, Knees, Hips) [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Change in circulating pro-inflammatory and anti-inflammatory cytokines (pg/mL) [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Change in Inflammatory biomarkers (ng/mL) [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Change in serum enzyme activity (U/L) [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Oxidative stress and adiponectin (µmol/L) [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Changein serum creatinine (µmol/L) [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Change in blood urea (mmol/L) [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Change in coagulation parameters [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Clinical tolerance [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
- Biological safety laboratory parameters [Time frame: Baseline (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)]
