[Oral recombinant adeno-associated virus gene medicine].
The efficacy of recombinant adeno-associated virus (rAAV) vector-mediated gene delivery to the gastrointestinal tract has been paid a considerable attention over the last 10 years, since our first report on the oral gene pill strategy in Nature Medicine, even though there are still several potential obstacles for this route to overcome in order to obtain efficient gene delivery. The preclinical results of oral rAAV gene medicine are summarized in this review, and special attention is paid on its pharmacokinetic and pharmacodynamic aspects with an emphasis on drug delivery, absorption, distribution and transduction. The rAAV based vectors have been shown promising results in human clinical trials with fewer safety concerns over other gene medicines. However, the underlying mechanisms and biopharmaceutical features of oral rAAV gene medicine remain to be explored extensively and intensively to develop this novel technology as a treatment for a wider range of diseases.
