  • Patent number: 9868952
    Abstract: The present invention relates to compositions and methods for development of resistance-proof siRNA therapeutics for prevention and treatment of influenza viral infections. The compositions include a pharmaceutical composition comprising siRNA molecules that target conserved regions of an influenza virus gene and a pharmaceutically acceptable polymeric carrier. In one embodiment, the polymeric carrier condenses the molecules to form a nanoparticle.

  • Patent number: 9642873
    Abstract: The present invention provides compositions and methods for using combinations of TGF?1 and Cox-2 inhibitors and TGF?1 and Hoxb13 inhibitors for the treatment of various medical conditions, including skin scaring due to trauma wounds and surgery, corneal and retina scaring due to injury and surgery, internal organ scaring due to injury and surgery, heart tissue scaring due to heart attack and surgery, and lung, liver, and kidney fibrosis due to inflammation and injury. One example is to use siRNA inhibitors to silence TGF?1 and Cox-2 at the same time, resulting in significant less scar formation.

  • Patent number: 9506063
    Abstract: The invention provides siRNA compositions that (1) interfere with viral replication of human papillomavirus (HPV), herpes simplex virus (HSV), and human immunodeficiency virus (HIV) in mucosal tissues, such as genital tissues, and (2) treat fungal infections. The compositions include siRNA molecules that target HPV, complexed with a dendrimer that treats and prevents genital herpes (HSV) and HIV. The compositions also include siRNA molecules that target HPV, complexed with a histidine-lysine (HK) polymer that treats and prevent fungus infection. The combined formulations of siRNA and dendrimer provide treatment of the infections from HPVs, HSVs, and HIVs. The combined formulations of siRNA and HK polymer provide treatment of HPVs and fungus infections.

  • Publication number: 20130123330
    Abstract: The present invention relates to compositions and methods for treating diabetic retinopathy and other ocular neovascularization diseases. In one embodiment, the composition comprises at least two different siRNA duplexes and a pharmaceutically acceptable carrier. One of the duplexes binds to an mRNA molecule that encodes VEGF, and the other binds to an mRNA molecule that encodes VEGFR2. In another embodiment, the composition further comprises an siRNA duplex that binds to an mRNA molecule that encodes TGF?1.
