Trial Outcomes & Findings for A 4-week Study to Evaluate the Efficacy and Safety of HP-5000 in Subjects With Knee Osteoarthritis (NCT NCT03277066)

NCT ID: NCT03277066

Last Updated: 2021-12-23

Results Overview

To evaluate efficacy of HP-5000 Active Topical Patch 1 and HP-5000 Active Topical Patch 2 compared with placebo for the treatment of Osteoarthritis of the knee as evaluated by change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score from baseline to week 4. WOMAC pain score is a scale that evaluate five items including walking, stair climbing, nocturnal, rest and weight bearing. Each item is rated on a scale of 0 to 4, with 0 being no difficulty and 4 being extremely difficulty. The total score is the sum of five items. The total score range from 0 to 20 with a low score considered a better outcome and a high score considered a worse outcome.

PRIMARY outcome

Timeframe: Baseline and 4 weeks

To evaluate efficacy of HP-5000 Active Topical Patch 1 and HP-5000 Active Topical Patch 2 compared with placebo for the treatment of Osteoarthritis of the knee as evaluated by change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score from baseline to week 4. WOMAC pain score is a scale that evaluate five items including walking, stair climbing, nocturnal, rest and weight bearing. Each item is rated on a scale of 0 to 4, with 0 being no difficulty and 4 being extremely difficulty. The total score is the sum of five items. The total score range from 0 to 20 with a low score considered a better outcome and a high score considered a worse outcome.
