Provided herein are methods and related compositions for administering viral transfer vectors and antigen-presenting cell targeted immunosuppressants.

Provided herein are recombinant viruses and artificially coated delivery systems, and methods of use.

The present disclosure provides therapeutic agents comprising oncolytic vaccinia viruses and NK cells, and uses thereof for preparation of drugs for treatment of tumors and/or cancers. The active ingredients of the therapeutic agents comprise an oncolytic vaccinia virus and NK cells, wherein the oncolytic vaccinia virus can selectively replicate in tumor cells.

The present invention provides methods for treating an individual having bladder cancer comprising intravesically administering to the individual an oncolytic virus. Also provided are pharmaceutical compositions and kits for treating bladder cancer.

The present invention provides methods for treating an individual having bladder cancer comprising intravesically administering to the individual an oncolytic virus. Also provided are pharmaceutical compositions and kits for treating bladder cancer.

The present disclosure provides therapeutic agents and uses thereof for drugs for treatment of tumors and/or cancers. The active ingredients of the therapeutic agents comprise an oncolytic virus that selectively replicate in tumor cells and comprise NK cells.

The present invention relates to a method for removing undesired anti-AAV antibodies from a blood-derived composition.

Disclosed is a pH-sensitive and bioreducible polymer-virus complex which can destroy tumor cells more effectively by increasing the efficiency of virus transduction. A pH-sensitive and bioreducible polymer contains (i) an escapable portion from immune reactions, (ii) a chargeable portion having one or more amine groups and (iii) a bioreducible portion including one or more disulfide linkages. The and to a pharmaceutical composition containing the polymer-virus complex. Also disclosed are a pharmaceutical composition containing the pH-sensitive and bioreducible polymer-virus complex and methods for treating cancer in a subject, employing the composition.

An adenovirus comprising an E1A polypeptide comprising one or more modifications and comprising an E4orf6/7 polypeptide comprising one or more modifications is described. Compositions and kits comprising the modified adenoviruses are also described. Further described is a method of treating a proliferative disorder in a subject comprising administering to the subject an adenovirus comprising the E1A polypeptide comprising one or more modifications and comprising the E4orf6/7 polypeptide comprising one or more modifications.

Provided are recombinant adeno-associated virus (rAAV) compositions for the expression of antibodies (e.g., anti-complement component 5 (C5) antibodies) in cells, and methods of treating disorders with the same (e.g., disorders associated with C5 activity (e.g., Paroxysmal Nocturnal Hemoglobinuria)). Also provided are compositions, systems and methods for making the rAAV compositions.
