Vitalis Therapeutics is a physician-researcher-founded pharmaceutical company developing non-opioid therapies for acute post-operative pain, with an initial focus on oral ketamine for patients recovering from total knee replacement. Its lead candidate, VS-1, is in planning for a Phase 2a clinical trial and is designed to reduce opioid use while supporting earlier mobility and recovery at home. The company works with orthopedic surgeons and uses a compounding-pharmacy pathway to pursue early access for interested patients.
