“…Although, this study revealed the safety and viability of Ad2-HIF injection in the myocardium, but due to small sample size, the results should be confirmed by larger series studies. 35 Yang and colleagues in a phase I clinical trial studied the arterial gene transfer of Ad-HGF in 18 patients with CAD (group A: 5 × 10 9 pfu, n = 6; group B: 1 × 10 10 pfu, n = 6; and group C: 2 × 10 10 pfu, n = 6). The trial did not report any serious adverse effects, such as fever, hemodynamic changes, arrhythmia, and other possible adverse events related to the Ad-HGF gene through 7, 21, and 35 days after the operation indicating that Ad-HGF is safe and feasible.…”
