STICKY SIRNA is a new class of interfering RNAs designed to dramatically enhance siRNA-mediated gene silencing in vivo. The stability and bioavailability of classical siRNA duplexes as well as the amount of dsRNA delivered to cells remain the limiting factors for efficient silencing. We have developed STICKY SIRNA which has a high RNA interference activity in eukaryotic cells and provides higher gene silencing efficiencies than those obtained using conventional siRNA, when introduced with the same delivery system. This was achieved by oligomerizing siRNAs by the addition of short “sticky” overhangs which significantly increases the siRNA and formulation stability, in vivo delivery, RNase protection and gene silencing without inducing pro-inflammatory cytokine responses. Therapeutic STICKY SIRNAs inhibiting tumor cell growth or inducing apoptosis have been successfully tested in vivo in lung metastatic cancer, melanoma xenograft and prostate cancer models (results published) and can be combined with chemotherapy treatments. Proven preclinical efficacy data and safety studies in mice have produced highly encouraging results supporting the track towards future drug candidates entering clinical development.
