CGS-200-5

There are currently no approved therapies that effectively manage moderate to severe OA pain without significant concerns related to tolerability, safety, or addiction potential.  Topical CGS-200-5 (5% capsaicin) has clinically been shown to significantly reduce OA knee pain.  In a recent Phase 2 study, CGS-200-5 reduced pain by 50% (based on WOMAC pain score) while demonstrating robust safety and tolerability. CGS-200-5 also demonstrated highly durable pain relief, with OA patients reporting the maintenance of pain relief efficacy through 90 days, the final time point of the Phase 2 study, following just four consecutive days of topical treatment at study start. Acknowledging the therapeutic potential of topical high-concentration capsaicin, the American College of Rheumatology recently revised its OA treatment guideline to conditionally recommend topical capsaicin for knee OA pain.

The FDA recently confirmed the eligibility of CGS-200-5 for the highly efficient 505 (b) (2) regulatory approval process and we anticipate filing a New Drug Application (NDA) for the product in 2024, with the potential for market clearance as early as 2024.

A topical product that can provide safe, effective and durable pain relief for OA patients has significant commercial potential. A recently completed, independent market research study projected that peak year sales of CGS-200-5 in the U.S. could exceed $750 million annually.
