VAS101 is a gel that contains curcumin (derived from the plant turmeric). VAS101 is designed to be applied topically (on the skin). The oral intake of curcumin has been shown to have anti-inflammatory and pain-relieving effects; however, when applied topically, its pain-relieving effects have not been previously evaluated. The aim of this study is to investigate if the topical application of a curcumin-containing gel (VAS101) can help reduce pain and symptoms associated with osteoarthritis of the knee.

If you are between 45 and 75 years old and have been diagnosed with osteoarthritis of the knee, we invite you to participate in this randomised, controlled study.

PLEASE NOTE: Travel to our office located in Duncraig is required on 3 occasions over 4 weeks

Eligible participants will be RANDOMLY allocated into ONE of TWO treatment conditions:

1. Application of a gel containing curcumin (VAS101) to your knee every 2 days, or or

This 4-week study consists of the following:

1. Participate in a 10-minute phone interview to discuss the study and assess your eligibility to participate.
2. Have an X-ray on your target knee. We will arrange a referral to your nearest SKG pathology
3. Attend a face-to-face assessment on 3 occasions (baseline, week 2, and week 4) located in our offices in Duncraig. During your in-person visit (approx. 90 minutes), you will complete questionnaires, collect a small urine sample, and complete several low-intensity exercises to test your knee function.
4. Apply the gel to your knee every 2 days (containing curcumin or a placebo).
