AVITA Medical’s Cohealyx Slashes Time to Skin Grafting by Nearly 20 Days in Interim Study
Summary: Interim results from the multi-center Cohealyx-I study show that AVITA Medical’s Cohealyx dermal matrix dramatically shortens time to skin grafting in full-thickness wounds. Compared with a literature benchmark (meta-analysis of ~900 patients using leading dermal matrices), Cohealyx reduced average grafting time from 33.2 days to 13.6 days (nearly 20-day improvement, p<0.001). In 40 patients, median time was 11 days, with 25% grafted within one week and 72% within two weeks. Investigators reported 90% satisfaction, even among first-time users. Cohealyx prepares a vascularized wound bed efficiently, complementing AVITA’s RECELL technology for autologous skin regeneration and offering potential benefits in burn and complex wound management.
Key Highlights:
- Nearly 20-day reduction in time to grafting (33.2 → 13.6 days, p<0.001)
- 72% of patients grafted within 2 weeks; some as early as 5 days
- 90% investigator satisfaction rate
- Supports faster wound bed preparation for subsequent grafting
