EXTON, PA, USA | August 5, 2008 | Isolagen(TM), Inc. (Amex: ILE) announced today positive top-line efficacy and safety results from two pivotal, Phase III clinical studies (Studies IT-R-005 and IT-R-006) of the Isolagen Therapy(TM) for the treatment of nasolabial folds, or wrinkles. Each study, conducted under an FDA Special Protocol Assessment (SPA), met all primary endpoints and was highly statistically significant, making this a major clinical milestone for the Company.
"This is a significant achievement for Isolagen and an important step towards bringing the first ever autologous cell therapy product to the market for aesthetic use. As the future evolves and current therapies continue to show their age, the need for novel skin rejuvenation products becomes evident. With these statistically significant results, we believe we are now in an excellent strategic position," said Nicholas L. Teti, Jr., Chairman of Isolagen. "These results further support the proof of principle for autologous cell therapy and open the door for further research in aesthetics, acne scars, burn scars and other clinical applications."
The pivotal, Phase III placebo-controlled studies investigating the efficacy and safety of Isolagen Therapy for the treatment of nasolabial folds, or wrinkles, evaluated a total of 421 people at 13 clinical sites across the United States. In Study IT-R-005, both the Evaluator and Patient evaluations met the co-primary endpoints and were statistically significant achieving p values of <0.0001 and 0.0001, respectively. In Study IT-R-006, statistical significance was also achieved for both primary efficacy endpoints, achieving p values of 0.0075 and <0.0001 for the Evaluator and Patient evaluations, respectively.
Top-line statistical results showed that p values at Month 6 following third injection were comparable to p values at Month 2, with both observation periods achieving statistical significance.
Top-line Statistical Results at Observation Visits (p values*):
005 Patient 005 Evaluator 006 Patient 006 Evaluator
Month 2 0.0001 0.0005 0.0003 0.0039
Month 4 0.0006 0.0003 0.0012 0.0002
Month 6 0.0001 <0.0001 <0.0001 0.0075
*p values less than or equal to 0.05 are considered statistically significant.
Preliminary safety analyses showed the Isolagen Therapy was well tolerated with safety results comparable to placebo in the clinical studies. No serious adverse events related to Isolagen Therapy were observed in the studies.
"I am excited by these positive study results suggesting a clinical benefit from the Isolagen Therapy, a novel therapy using a person's own cells for the treatment of wrinkles," said Stacy R. Smith, M.D., study investigator and Assistant Clinical Professor, Division of Dermatology, University of California San Diego. "I believe the aesthetics community would welcome a new, first in class, regenerative therapy. The results of these pivotal studies will generate even greater interest in the outcome of the ongoing Phase II/III clinical study of Isolagen Therapy for the treatment of acne scars, where there is a significant unmet need."
The Isolagen Process(TM) is a proprietary cellular processing system that creates a natural, living cell therapy. By multiplying a person's own collagen-producing cells, or fibroblasts, into tens of millions of new cells, a personalized treatment is created that is then returned to the person's skin. This first of its kind aesthetic treatment, known as the Isolagen Therapy, is designed to improve skin damage caused by the normal effects of aging, sun damage, acne and burns.
"We are thrilled with the positive results from our pivotal Phase III clinical studies of the Isolagen Therapy," said Declan Daly, President and Chief Executive Officer of Isolagen. "We intend to file our Biologics License Application (BLA) with the FDA in early 2009 and continue to progress our ongoing Acne trial. I want to thank the clinical investigators and congratulate the Isolagen team for their exceptional performance and clinical achievement in this groundbreaking pivotal study confirming our belief in this innovative approach to aesthetic skin therapy."
About the Studies
The goal of the Phase III multicenter, double-blind, randomized, placebo- controlled studies was to demonstrate the efficacy of three treatments of Isolagen Therapy compared with placebo in the treatment of bilateral nasolabial folds, or wrinkles, six months following the last study treatment, using the co-primary endpoints of:
-- Subject Wrinkle Satisfaction Assessment: the person's own assessment of the wrinkles using a 5-point wrinkle satisfaction scale, and an
-- Evaluator Wrinkle Severity Assessment: the evaluator's live assessment of each of the bilateral nasolabial fold wrinkles at rest using a 6-point ordinal wrinkle severity scale with a photoguide as a reference tool.
Isolagen's Phase III studies for wrinkles were conducted under the Food and Drug Administration's (FDA) Special Protocol Assessment (SPA) regulations. The SPA process results in an agreement with the FDA that successful clinical trial results will form the basis of an efficacy claim for a marketing application. Although significant, the SPA does not guarantee approval of a BLA.
Further, Isolagen is currently conducting a Phase II/III clinical program to investigate the Isolagen Therapy for the treatment of moderate to severe acne scars.
