A Phase 2 Clinical Trial to Examine the Comparative Effects on Osteoarthritic Knee Pain of CGS-200-1, CGS-200-5, and CGS-200-0

Study Purpose

This is a multi-center, randomized, double-blind clinical trial to examine the comparative effects on OAKP of CGS-200-1 (1% Capsaicin content) (N=40), CGS-200-5 (5% Capsaicin content) (N=40), and CGS-200 Vehicle (no Capsaicin) (N=40) in subjects with OA of the knees according to the 1986 American College of Rheumatology (ACR) criteria. Assigned doses will be applied at the clinic for 60 minutes on each of four consecutive days. Subjects will be randomized to one of the three Arms in this study: CGS-200-1 or CGS-200-5 or CGS-200 Vehicle (CGS-200-0). All subjects will receive 4 consecutive days of treatment and will then be followed up until the Day 94 visit. Even though both knee(s) will receive application of study test materials, with regard to reduction in WOMAC pain and VAS pain score associated with study treatments, only one knee will be indicated as the "Study Knee". This will be the knee with the highest WOMAC pain score at screening. If both knees have equal WOMAC pain scores at baseline, then the right knee will be considered the "Study Knee" with regard to WOMAC pain and VAS pain score reduction. Data will be collected from Day 1 through Day 5 and then again on Days 19, 35, 64 and 94 for efficacy, tolerability, and safety measures. The Investigators, all site staff and Clinical Research Organization (CRO) personnel (except the Medical Monitor providing safety oversight) directly involved in the study will remain blinded to the treatment assignment throughout the trial.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Exclusion Criteria:

  • - Spontaneously improving or rapidly deteriorating OA of the knee; - Rheumatoid or psoriatic arthritis, or a form of arthritis (e.g. gout, pseudogout), Paget's disease of bone, or any other disease affecting the joints that are inconsistent with a diagnosis of idiopathic OA; - History of labile or poorly controlled hypertension; - Use of steroids for 1 month prior to screening, or intraarticular-visco-supplementation within 3 months prior to screening; - Used any capsaicin-containing product on or in the vicinity of the knee within 4 weeks prior to screening; - Used topically applied products (including emollients or moisturizers) on or in the vicinity of the knees or shaved the knees within 2 days prior to the first application of study drug; or an open wound near the knee; cutaneous erythema or edema; any inflammatory skin lesions such as eczema or psoriasis; cutaneous infections; or any other compromise of the skin; - Requires or anticipates any surgical procedure within 3 months prior to screening, has had surgery on the affected joint within 6 months prior to screening, has a prosthesis at the index joint, or would require surgery while participating in the trial.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03528369
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
