About this study

Official title: A Randomized, Multi-Dose, Placebo-Controlled Pain Relief Study of 0.25% 920-CGS-200 in Subjects With Preexisting Knee Pain (for at Least 6 Months) Caused by Osteoarthritis (OA)

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.

This is a study of a 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. Both knees received study drug treatment but only one knee per subject was assigned as the "study knee".

Osteoarthritis knee pain was assessed by the 100 mm visual analog scale and the response criterion was a 50% or greater reduction in osteoarthritis knee pain from baseline. Baseline was defined as the visual analog scale recorded not more than 30 minutes before the first study drug application (on Study Day 1). For subjects in the once daily (QD) groups the osteoarthritis knee pain assessments were at 12 hrs after the initial application (during Study Day 1) and 24 hours (Study Day 2) after the initial application and then once in the morning on Study Days 3 - 28. For subjects in the twice daily (BID) groups the osteoarthritis knee pain assessments were at 12 hrs after the initial application (during Study Day 1) and 24 hours(Study Day 2) after the initial application and then once in the morning and once 12 hours later on Study Days 3 - 28.

Tolerability data were also collected as reported burning-stinging pain, erythema and pruritus at the site of application.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: Study Day 2

Secondary outcomes (2)
  1. Percentage of Subjects With 50% or Greater Pain Score Reduction From Baseline to Day 8 Post Study Drug Treatment.

    To evaluate the percentage of subjects who experience ≥50% reduction in osteoarthritis knee pain in the target knee compared with baseline after a 7 day period. 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.

    Measured: Study Days 1-7

  2. Percentage of Subjects With 50% or Greater Pain Score Reduction From Baseline to Day 28 Post Study Drug Treatment.

    To evaluate the percentage of subjects who experience ≥50% reduction in osteoarthritis knee pain in the target knee compared with baseline after 28 days. 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.

    Measured: Study Days 1-28

What does the primary outcome measure?

Percentage of Subjects With 50% or Greater Pain Score Reduction From Baseline to 24 Hours After First Dose of Study Drug Treatment. (time frame: Study Day 2). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
