AVITA Medical Achieves Positive Topline Pivotal Trial Results for Treatment of Stable Vitiligo Using the RECELL® System
- The study achieved its primary effectiveness endpoint of super-superiority
- AVITA Medical continues to plan for submission to FDA by the end of 2022
VALENCIA, Calif. and MELBOURNE, Australia, Sept. 12, 2022 (GLOBE NEWSWIRE) -- Avita Medical , Inc. (NASDAQ: RCEL, ASX: AVH) (Company), a regenerative medicine company leading the development and commercialization of first-in-class devices and autologous cellular therapies for skin restoration, today announced positive topline results from a pivotal randomized, controlled trial evaluating the safety and effectiveness of the RECELL® System for repigmentation of stable vitiligo lesions.
The study compared repigmentation success rates, in a design where each patient randomly received RECELL treatment in one portion of depigmented area and treatment with the study control in another portion of depigmented area. The study control treatment was the standard of care narrowband ultraviolet-B phototherapy, which is typical first-line treatment for vitiligo. Repigmentation was evaluated 6 months after treatment by an expert central review committee (CRC).
The CRC reported the following:
- Fifty-six percent (56%) of RECELL treatments (versus 12% of control treatments) resulted in repigmentation of more than 50% of the treated area
- Thirty-six percent (36%) of RECELL treatments (versus 0% of control treatments) resulted in repigmentation of at least 80% of the treated area, establishing super-superiority for the primary endpoint (p<0.025)
RECELL’s compelling safety profile to date is reflected in preliminary review of adverse events in this study.
These are the first results from a U.S. randomized, controlled trial of the RECELL System in treating patients with segmental and nonsegmental stable vitiligo and provide a foundation for communicating favorable clinical benefit in pursuit of FDA approval via submission of a PMA supplement for this indication later this year.
“Vitiligo often has a severe impact on quality of life and is a therapeutic area within which there have been very limited treatment options. We are excited by our topline data, as we are now closer to our goal of providing patients with a durable, clinically meaningful, one-time treatment for repigmentation,” said Dr. Mike Perry, Chief Executive Officer of AVITA Medical. “RECELL has the potential to address the unmet medical need for an estimated 1.3 million people in the U.S. who suffer from stable vitiligo, and further, we envision a potential opportunity for RECELL as part of a multi-modal treatment plan for patients achieving stability with JAK inhibitor treatment.”
“Repigmentation is challenging to manage and burdensome for patients with vitiligo,” said Iltefat Hamzavi, MD, of Henry Ford Hospital (Detroit, MI), lead investigator of the trial. “These are encouraging results that underscore the potential for RECELL to address repigmentation in patients with stable vitiligo in a rapid and sustained fashion which is distinct from existing therapies.”
Vitiligo is a disease that attacks pigment-producing cells, called melanocytes, resulting in their destruction or malfunction. The result is a loss of pigmentation in patches of skin. Vitiligo affects up to 2% of the population worldwide,i including up to 6.5 million Americans,ii with an estimated 1.3 million suffering from stable vitiligo. Vitiligo has a comparable psychosocial impact to other major dermatology diseases including psoriasis (thick, scaly skin) and atopic dermatitis (red, cracked skin).iii,iv,v Like these diseases, those living with vitiligo may suffer from poor body image along with low self-esteem, leading to an impaired quality of life.vi
ABOUT AVITA MEDICAL, INC.
AVITA Medical is a regenerative medicine company leading the development and commercialization of devices and autologous cellular therapies for skin restoration. The RECELL® System technology platform, approved by the FDA for the treatment of acute thermal burns in both adults and children, harnesses the regenerative properties of a patient’s own skin to create Spray-On Skin™ cells. Delivered at the point-of-care, RECELL enables improved clinical outcomes and validated cost savings. RECELL is the catalyst of a new treatment paradigm and AVITA Medical is leveraging its proven and differentiated capabilities to develop first-in-class cellular therapies for multiple indications, including acute traumatic wounds and repigmentation of stable vitiligo lesions.
AVITA Medical’s first U.S. product, the RECELL System, was approved by the U.S. Food and Drug Administration (FDA) in September 2018. The RECELL System is approved for acute partial-thickness thermal burn wounds in patients 18 years of age and older or application in combination with meshed autografting for acute full-thickness thermal burn wounds in pediatric and adult patients. In February 2022, the FDA reviewed and approved the PMA supplement for RECELL Autologous Cell Harvesting Device, an enhanced RECELL System aimed at providing clinicians a more efficient user experience and simplified workflow.
The RECELL System is used to prepare Spray-On Skin™ Cells using a small amount of a patient’s own skin, providing a new way to treat severe burns, while significantly reducing the amount of donor skin required. The RECELL System is designed to be used at the point of care alone or in combination with autografts depending on the depth of the burn injury. Compelling data from randomized, controlled clinical trials conducted at major U.S. burn centers and real-world use in more than 15,000 patients globally, reinforce that the RECELL System is a significant advancement over the current standard of care for burn patients and offers benefits in clinical outcomes and cost savings. Healthcare professionals should read the INSTRUCTIONS FOR USE - RECELL Autologous Cell Harvesting Device (https://recellsystem.com) for a full description of indications for use and important safety information including contraindications, warnings, and precautions.
In international markets, our products are approved under the RECELL System brand to promote skin healing in a wide range of applications including burns, acute traumatic wounds, vitiligo, and aesthetics. The RECELL System is TGA-registered in Australia, received CE-mark approval in Europe and has PMDA approval in Japan. To learn more, visit www.avitamedical.com.
