Trial Outcomes & Findings for Colchicine for the Treatment of Osteoarthritis of the Knee (NCT NCT03913442)

NCT ID: NCT03913442

Last Updated: 2025-02-03

Results Overview

VAS is a tool widely used to measure pain. A patient is asked to indicate his/her perceived pain intensity (most commonly) along a 10 mm horizontal line, and this rating is then measured from the left edge (=VAS score). The total score range is 0 (no pain) to 10 (worst pain imaginable); the higher the score, the worse the pain.

Placebo
Placebo in capsule identical to study drug Placebo oral capsule: Placebo 0.8 mg or 0.6 mg orally once daily for 3 months
Colchicine
0.6 or 0.8 mg orally once daily. Because recent studies suggest that a dose of 0.6mg may be sufficient for chronic inflammatory suppression and may reduce the already low risk of toxicity of 0.8mg, for the remainder (second half) of the study the dosage will be switched from 0.8mg to a 0.6mg dose to allow comparison of the two doses. Colchicine 0.8 mg or 0.6 mg orally once daily: Colchicine 0.8 mg orally once daily for 1.5 months, and then 0.6 mg once daily for the remainder of the time (1.5 months)

SECONDARY outcome

Timeframe: Baseline, 3 Months

The KOOS survey is comprised of 42 questions. The questions are divided into 5 sub-categories: symptoms/stiffness (7 questions), pain (9 questions), function/daily living (17 questions), function/sports and recreational activities (5 questions), and quality of life (4 questions). The KOOS Pain Score refers to a specific subscale within the KOOS questionnaire that measures the severity of knee pain experienced by a patient, consisting of nine questions where each response is scored on a scale from 0 (no pain) to 4 (extreme pain), with a higher score indicating greater pain intensity; the overall pain score is then calculated as a percentage of the maximum possible score, where 0 represents the worst possible pain and 100 represents no pain at all.

SECONDARY outcome

Timeframe: Baseline, 3 Months

The KOOS survey is comprised of 42 questions. The questions are divided into 5 sub-categories: symptoms/stiffness (7 questions), pain (9 questions), function/daily living (17 questions), function/sports and recreational activities (5 questions), and quality of life (4 questions). Each item on the KOOS is scored on a scale from 0 (no problems) to 4 (extreme problems), and then the scores are calculated to generate a final score between 0 and 100. The KOOS stiffness score is a percentage from 0 to 100 that measures how much stiffness a patient experiences in their knee. A score of 0 indicates the most stiffness, while a score of 100 indicates no stiffness.

Timeframe: Baseline, 3 Months

The KOOS's five patient-relevant dimensions are scored separately: Pain (9 items); Symptoms/Stiffness (7 items); Function, Daily Living (17 items); Function, Sports and Recreational Activities (5 items); Quality of Life (4 items). The KOOS Physical Function items are scored on a Likert scale from 0 to 4, with 0 indicating no problems and 4 indicating extreme problems. The scores for each dimension are then transformed to a scale from 0 to 100, where 0 represents extreme problems with knee function and 100 indicates no problems at all.

A KOOS Quality of Life score ranges from 0 to 100, where 0 represents the worst possible knee-related quality of life and 100 indicates no problems at all. A higher score indicates better quality of life related to the knee.
