Avita Medical announces new Recell trial

Latest News

Avita Medical (ASX:AVH), a global regenerative medicine company, has announced the commencement of a randomised, controlled clinical study of its RECELL Autologous Cell Harvesting Device in the treatment of significant superficial partial and mid-thickness pediatric burns, including scald injuries.

The clinical trial is being conducted by the Queensland University of Technology (QUT) in collaboration with the Pegg Leditschke Children’s Burns Centre at Lady Cilento Children’s Hospital in Brisbane. 

Treatment of children in the trial has commenced. 

The pediatric clinical trial is being led Dr Bronwyn Griffin and Professor Roy Kimble.

The company said the current standard of care for children with partial-thickness burns is cleaning of the wound followed by a dressing application.

"Limitations of the standard of care include delay in healing of the burn injury, scarring, and pain," it said.

The clinical trial will include approximately 90 patients under 18 years old. Patients will be randomised into one of three groups and will be treated either with the RECELL System and Biobrane dressing, the Biobrane dressing alone, or standard care (silver impregnated silicone lined dressing).

The trial's primary endpoint will be days to re-epithelization of the burn injury. Secondary endpoints include pain, patient satisfaction and scarring.    

The RECELL System uses a small amount of a patient’s own skin to prepare Spray-On Skin Cells at the point of care in as little as 30 minutes.

A small skin sample is enzymatically and mechanically processed in the RECELL System at the point of care to isolate the skin cells to produce a suspension of Spray-On Skin Cells. The regenerative cell suspension includes keratinocytes, fibroblasts, and melanocytes, which play a critical role in wound healing. The suspension can be sprayed directly on a second-degree burn or with an expanded skin graft on a third-degree burn, allowing for broad and even distribution of live cells across the entire wound bed.

"The RECELL System can be used to prepare enough suspension to treat a wound up to 80 times the size of the donor skin sample, so a skin sample approximately the size of a credit card can be used to treat a wound that covers an adult patient’s entire back," said the company.
