Study of Intra-articular Delivery of tgAAC94 in Inflammatory Arthritis Subjects

The 13G01 clinical trial is a Phase I/II dose escalation study designed to be conducted in adults with inflammatory arthritis who have persistent moderate or severe swelling in one or more joints, without a disease severe enough to warrant a change in regimen for the next three months. The study will permit subjects who are concurrently on anti-tumor necrosis factor (TNF)-alpha antagonists. For subjects on disease modifying antirheumatic drugs (DMARDs), a stable regimen for inflammatory arthritis for the previous three months, with no changes in doses in the four weeks prior to screening will be required. The primary objectives are: 1. to evaluate the safety of intra-articular administration of tgAAC94 in subjects currently taking TNF-alpha antagonists, and 2. to evaluate the safety of repeat intra-articular administration of tgAAC94 (gene therapy vector).
