Targeted Genetics to Report Interim Data From a Phase I/II Clinical Trial of tgAAC94 in Patients With Inflammatory Arthritis and Highlight AAV Development Platform in 9 Additional Abstracts at

ASGT Annual Meeting

SEATTLE, WA--(Marketwire - May 30, 2007) - Targeted Genetics Corporation (NASDAQ: TGEN) and its academic and corporate collaborators will report data in 10 oral and poster presentations, as well as Scientific and Media sessions, at the 10th Annual Meeting of the American Society of Gene Therapy (ASGT), May 30 - June 3 in Seattle, Washington.

Philip J. Mease, M.D., clinical professor at the University of Washington School of Medicine, chief of rheumatology clinical research at the Swedish Medical Center, practicing physician with Seattle Rheumatology Associates and Targeted Genetics' Principal Investigator, will discuss interim safety and efficacy data from an ongoing Phase I/II clinical trial of tgAAC94 in patients with inflammatory arthritis. Additional presentations will highlight Targeted Genetics' collaborations in the areas of HIV/AIDS vaccines and Huntington's disease, as well as basic and applied AAV vector biology and production.

In addition, Barrie J. Carter, Ph.D., Executive Vice President and Chief Scientific Officer of Targeted Genetics, will present an "Industry Perspective on Recruitment of Subjects for Clinical Trials" at a Scientific Symposia round table discussion on the ethics of patient selection. Dr. Mease will present "Gene therapy as the next step in biotech development and the biologic therapeutic continuum" at a Media Session on the use of gene therapy to provide systemically circulating anti-TNF inhibitors to reduce signs and symptoms in patients with inflammatory arthritis.

"As a company committed to developing AAV-based therapies for diseases with significant unmet medical need, advancing both the scientific and the commercial potential of our programs is of great importance," said H. Stewart Parker, president and chief executive officer of Targeted Genetics. "These presentations at ASGT underscore the progress being made in our product development programs and in multiple areas of research. Our product development platform is built on a solid foundation of AAV biology, and we are pleased to share the advances that we and our collaborators have made in this area with the gene therapy community."
