ClinConnect Summary
This clinical trial is studying the effects of a medication called Diacerein (Artrodar®) on knee osteoarthritis, a condition where the cartilage in the knee joint breaks down, causing pain and stiffness. The researchers want to see if Diacerein can help improve the structure of the cartilage in the knee. To do this, half of the participants will receive Diacerein, while the other half will receive a placebo, which looks like the medication but doesn’t contain any active ingredients. The trial will use MRI scans to measure changes in the cartilage over time.
To participate in this study, you need to be between 40 and 65 years old and have been diagnosed with knee osteoarthritis. Other important factors include having a specific level of severity in your condition and being in good overall health. If you meet these criteria, you'll be asked to attend regular appointments where you may receive the medication or placebo, and have MRI scans taken. This trial is currently recruiting participants, and it’s a great opportunity to contribute to research that could improve treatment for knee osteoarthritis.
