For Immediate Release

Many Gene Therapies Advancing Toward Approval and Market Introduction within the Next Few Years, According to a Forthcoming Report from MedMarket Diligence

FOOTHILL RANCH, CAŚ While research and development of gene therapy has experienced its share of hurdles in recent years, it has also begun demonstrating its potential. As a result of the technical sophistication and aggressive development by commercial and academic entities, the continued financial support evincing its real promise, and the unabated clinical need of numerous patient populations, gene therapy is indeed headed toward market approval and introduction by the end of this decade.

Advances in utilization of viral vectors (adenoviruses, AAVs, retroviruses, HSV, lentiviruses, and RNA viruses) and non-viral vectors (cells, liposomes, DNA and others) have reached a level of sophistication for targeting single gene deficiencies, cancers, cardiovascular conditions, CNS conditions, tissue repair and other applications that is driving renewed venture capital investment and much commercial development. Despite a limited number of overstated setbacks, a stunning number of companies and academic institutions are aggressively developing these gene therapies, with many in later stage clinical trials.

The MedMarket Diligence report on "Gene Therapy: Worldwide Current Development Status and Market Potential" (report #A605), publishing in December 2003, will be a detailed assessment of the status of development in gene therapy and the outlook for its commercial introduction. The report will detail the techniques, technologies, and target clinical applications being pursued, with detailed data and insights on specific products and the numerous competitors vying to reach the market. The report will provide a well-grounded assessment of the remaining clinical and commercial hurdles, providing a ten-year outlook for genetically based therapies. The report's analysis will reveal windows of opportunity for current or hopeful competitors.
