VALENCIA, Calif., April 14, 2026 -- AVITA Medical

, Inc. (NASDAQ: RCEL, ASX: AVH), a leading therapeutic acute wound care company, today announced positive interim results from its Cohealyx-I multi-center study demonstrating a reduction of nearly 20 days in mean time to skin grafting (13.6 days vs 33.2 days benchmark) for patients with full-thickness wounds. The results demonstrated statistical superiority (p<0.001) versus a literature-derived benchmark, based on the lower bound of the 95% confidence interval (28 days). The benchmark was derived from a meta-analysis of published data on leading dermal matrices, representing approximately 900 patients.

The interim analysis of 40 patients showed a median time to grafting of 11 days. Grafting was achieved as early as 5 days, with 25% grafted within 7 days, and 72% grafted within 14 days. Investigators reported 90% satisfaction at the time of grafting, including among predominantly first-time users, supporting consistent performance and potential for broader adoption in clinical practice.

“Preparing the wound bed efficiently remains one of the key challenges in managing full-thickness wounds,” said Derek Bell, MD, Professor of Plastic Surgery and Kessler Burn Director, University of Rochester Medical Center, Rochester. “These interim results show that Cohealyx supports vascularization and enables earlier grafting, which is central to improving patient outcomes. Importantly, these results were achieved across a myriad of diverse and complex wounds.”

“This data strengthens our belief that Cohealyx can set a new benchmark in wound bed preparation,” said Cary Vance, Interim Chief Executive Officer of AVITA Medical. “The meaningful reduction in time to grafting and high investigator satisfaction highlight its potential as a differentiated solution with the ability to drive broader adoption as we work to improve each stage of the wound healing pathway.”

The data will be presented by Dr. Bell and Jonathan E. Schoen, MD, MPH, FACS, FABA, Medical Director, UMCNO Verified Burn Center, and Associate Professor of Clinical Surgery, Section of Burns/Trauma/Critical Care Surgery, LSUHSC School of Medicine at New Orleans, during an AVITA Medical symposium on Wednesday April 15.

About Cohealyx

Cohealyx is a collagen-based dermal matrix designed to support vascularization and optimize the wound bed for closure. It is intended for use in staged surgical procedures for acute full-thickness wounds and integrates with AVITA Medical’s broader portfolio, including RECELL

, to support efficient progression through the healing pathway.

About Cohealyx-I

Cohealyx-I is a prospective, single-arm, post-market, multi-center study evaluating the safety and performance of Cohealyx in patients with full-thickness wounds following surgical excision. The primary endpoint is time to autografting, assessed against a literature-derived performance benchmark.

Patients underwent a staged surgical approach, with Cohealyx applied to the wound bed following excision and autografting performed once adequate vascularization was achieved. Secondary endpoints include graft take, wound healing, and safety outcomes.

Patients are followed for approximately six months post-grafting to assess durability of outcomes and monitor adverse events.
