Adenovirus (Ad) vectors are currently the most commonly utilized gene transfer vectors in humans worldwide. Unfortunately, upon contact with the circulatory system, Ads induce several, innate, complement-dependent toxicities that limit the full potential for Ad-based gene transfer applications. Therefore, we have constructed several novel Ad5-based vectors, ‘capsid-displaying’ as fiber or pIX fusion proteins, a complement-regulatory peptide (COMPinh). These novel Ads dramatically minimize Ad-dependent activation of the human and non-human primate complement systems, as determined by several assays. In summary, our work has shown that a novel COMPinh-displaying Ad5 has the potential for broadening the safe use of Ad vectors in future human applications.
