TARGETED GENETICS’ INFLAMMATORY ARTHRITIS

PHASE I/II TRIAL PLACED ON CLINICAL HOLD

Seattle, WA - July 24, 2007 - Targeted Genetics Corporation (Nasdaq: TGEN) announced that after recent discussions with the United States Food and Drug Administration (FDA), the development program of tgAAC94, an investigational therapy for the treatment of inflammatory arthritis, has been placed on clinical hold.

As a precautionary measure, the FDA stopped further administration of tgAAC94 due to the uncertainty of the cause of a serious adverse event (SAE) that occurred in one subject enrolled in the study. Currently, there is insufficient information to draw conclusions as to the cause of the SAE, and therefore the study will remain on clinical hold while additional data is gathered and analyzed. Subjects already enrolled in the study will continue to be followed and monitored. Since the trial began in October 2005, 127 subjects have received an initial dose of active drug or placebo, and 74 subjects out of the total 127 have received a second dose of active drug.

“Our primary concern remains that of the safety of the patients, and we are working diligently with the study’s Data Safety Monitoring Board and the FDA to determine the cause of this unexpected event as quickly as possible,” said H. Stewart Parker, president and chief executive officer of Targeted Genetics.

The Phase I/II study is designed to assess the safety and potential efficacy of different doses of tgAAC94 administered directly to affected joints of subjects with inflammatory arthritis. tgAAC94 is an investigational therapy that utilizes an adeno-associated virus (AAV) vector to deliver the gene encoding a soluble form of the receptor for TNF-alpha (TNFR: Fc). The TNFR:Fc protein is a potent inhibitor of tumor necrosis factor-alpha (TNF-alpha), a key mediator of inflammation. In March 2006, the Company received approval from the FDA to amend its protocol for the tgAAC94 clinical trial to include a higher dose group and increase the number of patients. 127 adults have been randomized into three dose levels to receive a single intra-articular injection of either tgAAC94 or placebo into the knee, ankle, wrist, metacarpophalangeal or elbow, followed by an open-label injection of tgAAC94 after 12 to 30 weeks, depending on when arthritis symptoms in the target joint meet criteria for re-injection.

The interim data reported by our investigators at leading scientific meetings in June 2006, November 2006 and June 2007, support the safety and tolerability of single and repeat intra-articular injections of tgAAC94 to affected joints at doses up to 1x10(13) DNase Resistant Particles per milli-liter (DRP/mL) of joint fluid in subjects with and without systemic TNF-alpha antagonists. This interim data also suggest that treatment with tgAAC94 may lead to improvements in signs and symptoms of arthritis in injected joints.

About tgAAC94

tgAAC94 is being developed as a supplemental therapeutic to systemic anti-TNF-alpha protein therapy for use in patients with inflammatory arthritis who have one or more joints that do not fully respond to systemic protein therapy. The product candidate uses Targeted Genetics' recombinant AAV (rAAV) vector technology to deliver a DNA sequence that encodes a soluble form of the TNF-alpha receptor (TNFR: Fc). Soluble TNFR:Fc inhibits the immune stimulating activity of TNF-alpha. Direct injection of tgAAC94 into affected joints leads to the localized production of secreted TNFR:Fc within joint cells, reducing the activity of TNF-alpha within the joint and, potentially, leading to a decrease in the signs and symptoms of inflammatory disease and inhibition of joint destruction. The Company's rAAV technology platform is used to deliver genes and is based on AAV, a naturally occurring virus that has not been associated with any disease in humans.
