The trial is looking for adults aged 40 to 75 with knee osteoarthritis and ongoing knee pain. It tests whether CBD tablets that dissolve in the mouth reduce pain compared with a placebo (dummy tablet).

40 to 75 years
Sex
All sexes. Women who can still get pregnant must use two effective types of birth control. Men must use effective contraception.
Disease stage
Knee osteoarthritis of KL Grade II-III (moderate). Knee pain for at least three months, on at least half of the days. Pain score (VAS) of 4 or more.
Earlier treatment
No knee injections (cortisone, PRP, hyaluronic acid) in the last 3 months. No opioid pain medicine just before the study.

Main reasons for not taking part

  • Pregnant or breastfeeding women
  • History of cannabis abuse or dependence
  • Bleeding or clotting problems, stroke or heart attack in the last 3 months

About the trial

What the trial wants to find out

The purpose of this study is to see if cannabidiol (CBD) orally dissolving tablets (ODTs) can lessen pain, improve function, and improve patient satisfaction in cases of knee osteoarthritis. CBD comes from the cannabis plant and is non-psychoactive (i.e. does not produce a 'high' or altered mental state) as compared to tetrahydrocannabinol (THC), another compound found in cannabis. Researchers are studying different forms of CBD for potential use in treating pain, inflammation, and illnesses.

The 2 groups in the trial

  • CBD GroupTreatment being tested

    The first cohort will take two 25mg cannabidiol (total dose: 50mg) Orally Disintegrating Tablets (CBD ODT) three times daily for a maximum dose of 150mg per day.

    Treatment: Cannabidiol (CBD)

  • Placebo GroupPlacebo, for comparison

    Cohort 2 will receive the same instructions, but with the placebo Orally Disintegrating Tablets (ODT) instead.

    Treatment: Placebo
