A drug-free gel with phospholipid vesicles (TDT 064) reduced knee osteoarthritis pain and stiffness about as well as the oral drug celecoxib in a study of over 1,300 people over 12 weeks. The tiny phospholipid particles penetrate skin to reach the joint, possibly by lubricating cartilage. Side effects were mild and mostly skin-related.
Researchers reviewed preclinical and clinical studies of TDT 064, including randomized phase III trials comparing it to celecoxib (an oral anti-inflammatory) and placebo in patients with knee pain from osteoarthritis.
