Avita Medical: New Randomized Trial Shows ReCell Heals Donor Sites Faster

Skin donor sites heal just over 30% faster with ReCell® in 106-patient randomized controlled trial Superior wound healing and aesthetic appearance in ReCell®-group The 3rd positive clinical trial recently announced by Avita Medical

Avita Medical advises deploying a suspension of cells generated from a ReCell® medical device onto a skin donor site can speed up healing by 30.7% and deliver a superior final outcome, according to the results of a randomized controlled trial involving 106 patients who received skin grafts.

Avita, a regenerative medicine company focused on the treatment of wounds and skin defects, said the findings reported in the British Journal of Surgery (BJS) further supported its growing data package around its ReCell® autologous cell harvesting device. This is the 3rd randomized controlled trial announced in recent weeks: last month, the Company presented data from two trials conducted at leading burns centers across the US, including successful results from its pivotal trial needed for PMA approval with the Food and Drug Administration.

Avita’s CEO Mike Perry: “We are excited about these results, as together, the data show that ReCell® can be deployed both to reduce patient trauma, and to help patients heal faster.”  He added, “Our pivotal trial in the US, announced last month, showed how ReCell® allowed doctors to successfully treat burns using about 30% less donor skin. Now, in China, surgeons have shown that the donor site itself can heal some 30% faster when treated with Regenerative Epithelial Suspension™ made using the ReCell® device. Demonstration of clinical benefit for treatment of burn injuries and treatment of donor sites further substantiates the key, versatile role for ReCell® in burn care.”

The BJS paper — Randomized clinical trial of autologous skin cell suspension for accelerating re-epithelialization of split-thickness donor sites — was based on work by a team of burns and plastic surgeons at the Sun Yat Sen University Hospital, in Guangzhou, China, led by Prof. J. Zhu. The Chinese investigators wished to explore whether donor sites for skin grafts healed faster and better if ReCell® was deployed alongside the main standard of care, which was a hydrocolloid dressing. Over a period of some 18 months, a total of 106 patients were recruited, with 53 in either the Control or ReCell®-treated groups, amongst patients who presented at the hospital requiring split-thickness skin grafts.

The researchers evaluated how long it took for the epithelial layer of skin to restore on donor sites, with and without ReCell®, a device that allows surgeons to deliver a suspension of skin cells to aid tissue repair and skin regeneration. They reported that the median time to complete re-epithelialization was 9.0 days in the ReCell®-treated group, compared with 13.0 days in the control group, a 30.7% difference that was a statistically significant (p < 0.001).

The authors said both patients and independent observers evaluated that the donor sites treated with autologous skin cell suspension displayed better physical attributes and patients were more satisfied with healing quality. Early and rapid re-epithelialization is thought to enhance wound healing, improve long-term aesthetic appearance, and deliver ‘appropriate pigmentation,’ they said.

“The autologous skin cell suspension is produced quickly and is available immediately for wound application,” the investigators said. “This study suggests that its use [on] skin graft donor [sites] should promote healing and improve long-term aesthetic results.”

Avita said the positive data reflected the growing interest about ReCell® amongst burns surgeons in China. In an earlier trial, Zhu’s team in Guangzhou showed successful healing of chronic wounds with the ReCell® device.
