Osteoarthritis, the most common form of arthritis, affects more than 32.5 million Americans and more than 300 million people worldwide; symptomatic knee osteoarthritis is especially prevalent and disabling, with 40% of men and 47% of women developing it in their lifetimes. The first stage of the trial, a Phase I open-label dose-escalation study, was completed to evaluate safety and tolerability and to determine optimal dosing.

The ongoing Phase IIa stage is a double-blind, randomized, placebo-controlled trial, assessing both safety and efficacy, with endpoints measuring joint pain and function versus placebo at 3, 6, and 12 months post-injection. An interim analysis, conducted by an independent third party, was designed to evaluate the potential benefits of expanding enrollment from 130 to 180 patients and to identify possible responder sub-populations. To date, 134 patients have completed the 3-month follow-up period, the trial’s primary timepoint for measuring key endpoints.
