Gene therapy aims to complement or, ideally, correct defective genes. The broad clinical application of this emerging technology requires the development of safe high-capacity gene delivery vehicles that combine efficient transduction of dividing as well as quiescent cells with sustained transgene expression. Here we present a new hybrid vector system that unites favorable attributes of adenoassociated virus (AAV) and adenovirus (Ad) vectors in a single particle. This was achieved by inclusion of Ad packaging elements in different sized recombinant AAV genomes. In the presence of AAV replicative functions and a recombinant helper Ad, AAV/Ad hybrid particles were generated via encapsidation of AAV-dependent replicative intermediates into Ad capsids. In stringent in vitro models based on transduction of proliferating cells we show that AAV/Ad hybrid vectors are superior to Ad vectors in establishing prolonged transgene expression and can be used to deliver DNA fragments of at least 27 kb. © 2001 Academic Press.
