Brief Summary
This is a study of an over-the-counter, capsaicin-based (0.25%) topical analgesic for management of osteoarthritis knee pain meeting the US Food and Drug Administration's (FDAs) Tentative Final Monograph (TFM) guidance for "External Analgesic Drug Products For Over-the-Counter Human Use," published in the Federal Register on February 8, 1983 (final proposed 21 CFR 348). Subjects meeting the inclusion criteria and not meeting the exclusion criteria were randomized into one of four groups: once daily treatment with active product, once daily treatment with product vehicle (no capsaicin), twice daily treatment with active product, and twice daily treatment with product vehicle (no capsaicin), all for 7 consecutive days of treatment. The twice daily treatments were spaced approximately 12 hours apart. Osteoarthritis knee pain was assessed by the 100 mm visual analog scale. Osteoarthritis knee pain assessments were done each day for 28 days. Tolerability data were also collected.

Outcome Measures
Primary Outcomes (1)
Percentage of Subjects With 50% or Greater Pain Score Reduction From Baseline to 24 Hours After First Dose of Study Drug Treatment.
To evaluate the percentage of subjects who experience ≥50% reduction in osteoarthritis knee pain in the target knee compared with baseline at 24 hours following the first study drug treatment. Subjects in the once daily application group recorded their knee pain in a diary twice: at 12 hrs (± 1 hr) after their initial application and then again within ≤30 minutes before their daily topical application which was to be applied at 24 hrs (± 1 hr) after their previous day's application on all subsequent study days. Subjects in the twice daily application group recorded their knee pain in a diary within ≤30 minutes before each application on all study days. Subjects used a 100mm visual analogue scale when assessing their knee pain.
Study Day 2
Secondary Outcomes (2)
Percentage of Subjects With 50% or Greater Pain Score Reduction From Baseline to Day 8 Post Study Drug Treatment.
Study Days 1-7
Percentage of Subjects With 50% or Greater Pain Score Reduction From Baseline to Day 28 Post Study Drug Treatment.
Study Days 1-28
Study Arms (4)
Once daily-Active
ACTIVE COMPARATOR40 subjects receiving once daily application of complete drug product (contains 0.25% capsaicin) to the knee
Once daily-Vehicle
PLACEBO COMPARATOR20 subjects receiving once daily application of drug product vehicle (i.e., with no capsaicin) to the knee
Twice daily-Active
ACTIVE COMPARATOR40 subjects receiving twice daily application of complete drug product (contains 0.25% capsaicin) to the knee
Twice daily-Vehicle
PLACEBO COMPARATOR20 subjects receiving twice daily application of drug product vehicle (i.e., with no capsaicin) to the knee
Interventions
Over-the-counter Tentative Final Monograph compliant product with 0.25% capsaicin
This is the vehicle for the active treatment drug product, but without capsaicin
