Detailed Description
This is a multicenter, randomized, double-blind, placebo-controlled, parallel group, 4-week trial of a formulation of AMZ001 once or twice daily versus placebo twice daily, including a single-blind treatment group with a commercial gel four times daily.
Participants will be evaluated for osteoarthritis by X-ray images of the knees and one knee will be selected for treatment as the target knee.
The study gel will be applied directly to that knee throughout the 4 weeks of the study.

- Body Mass Index > 45.0 kg/m2.
- Generalized skin irritation, previous skin reactions upon use of topical NSAIDs, current skin irritation or redness at the planned site of gel application, or significant skin disease including psoriasis, as judged by the investigator.
- Known presence of a ulcer or any gastrointestinal bleeding within 6 months prior to screening.
- Use of moderate or higher doses of opioid medication for the treatment of pain within 6 weeks before the screening visit.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
WOMAC Pain Sub-score
Time Frame: baseline, week 4
|
Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain sub-score (questions 1-5; score 0 [no pain]-50 [extreme pain]) on target knee.
The WOMAC scores were normalized to a 0-100 point scale for data analysis, where higher scores indicate greater pain, stiffness or difficulty in performing daily tasks.
|
baseline, week 4
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
WOMAC Total Score and WOMAC Function and Stiffness
Time Frame: baseline, week 4
|
Change from baseline in Western Ontario McMasters Universities Osteoarthritis Index (WOMAC) total score and WOMAC function (degree of difficulty experienced in performing daily activities - 17 questions score 0-170) and stiffness (the degree and timing of joint stiffness - 2 questions score 0-20).
The WOMAC scores were normalized to a 0-100 point scale for data analysis, where 0 is no pain and higher scores indicate greater pain, stiffness or difficulty in performing daily tasks.
|
baseline, week 4
|
WOMAC Pain Weight-bearing Score and Non-weight-bearing Score
Time Frame: baseline, week 4
|
Change from baseline in Western Ontario McMasters Universities Osteoarthritis Index (WOMAC) pain weight-bearing score (questions 1,2, & 5; score 0-30) and non-weight-bearing score (questions 3&4; score 0-20) on target knee.
The WOMAC scores were normalized to a 0-100 point scale for data analysis, where 0 is no pain and higher scores indicate greater pain, stiffness or difficulty in performing daily tasks.
|
baseline, week 4
|
ICOAP Scores
Time Frame: baseline, week 4
|
Change from baseline in Intermittent and Constant Osteoarthritis Pain (ICOAP) scores (score 0 [no pain]- 4 [extreme pain]).
ICOAP scores were normalized to a 0-100 point scale, where 0 is no pain and higher scores indicate greater pain.
|
baseline, week 4
|
Physical Function
Time Frame: baseline, week 4
|
Change in baseline in physical function assessed by the chair-stand test.
The test measures the maximum number of chair stand repetitions possible in a 30-second period with out using the arms.
Where 0 is no repetition completed and higher numbers corresponds to greater repetitions and physical function.

Proportion of Responders as Per OMERACT-OARSI Criteria
Time Frame: week 4
|
Outcome Measures in Rheumatology- Osteoarthritis Research Society International (OMERACT-OARSI) response involves changes that are deemed to be clinically relevant in three domains: pain, function, and PGA (Patient Global Assessment).
For each of these domains, ranges are defined for absolute and percent changes from baseline that correspond to "high improvement" and "moderate improvement".
OMERACT-OARSI response is defined as either high improvement in at least 1 of WOMAC pain and function scores OR moderate improvement in at least 2 of WOMAC pain scores, WOMAC function score or Patient Global Assessment (PGA)
