Undenatured Type II Collagen for Knee Osteoarthritis Pain (Three-Arm Trial)
Official title: Randomized Clinical Trial to Analyze the Efficacy and Safety of Undenatured Type II Collagen Product on Joint Pain in Patients Diagnosed With Osteoarthritis
Run by Universidad Católica San Antonio de Murcia · NCT07870967 · Data updated 2026-11-12
This study tests whether taking undenatured type II collagen capsules once daily for 4 months can reduce knee pain in adults with knee osteoarthritis, compared with two collagen formulations and a placebo.

Is this trial a fit for you?
✓Likely a good fit
Adults over 30 with knee osteoarthritis (functional grades I–III) and persistent knee pain (baseline VAS ≥ 30 mm) who are not using narcotic or steroidal anti-inflammatory drugs.
✕Probably not a fit
Individuals with obesity (BMI ≥ 32 kg/m2), certain chronic inflammatory diseases, or those taking joint-health supplements may not experience benefit.

What this trial studies
This randomized, double-blind, three-arm trial compares Nuvicol II, Nuvicol SII, and placebo in adults with knee osteoarthritis and persistent knee pain. Over 4 months, participants will take one capsule daily and undergo regular visits to assess pain, function, biomarkers, and safety. Primary outcome is knee pain on a visual analog scale, with secondary measures including KOOS, WOMAC, muscle function, analgesic use, and cartilage degradation biomarkers. Safety labs and adverse events are monitored throughout the study. The trial is conducted at UCAM HiTech in Murcia and is led by Universidad Católica San Antonio de Murcia.
Why it matters
Potential benefit: If successful, participants could experience meaningful reductions in knee pain and improvements in joint function.
How similar studies have gone: Previous studies in joint health have explored undenatured type II collagen with variable outcomes; this trial adds a three-arm comparison to clarify efficacy signals.
