Abstract: Polymeric conjugates comprising a polymeric matrix having associated therewith an agent that down-regulates an activity or expression of a polypeptide associated with onset or progression of melanoma, and optionally and preferably, an additional agent that acts in synergy with said agent, are provided. Synthetic methodologies for preparing these conjugates and uses thereof in treating melanoma and other cancerous diseases are also provided.

Abstract: A polymeric nanoparticle is disclosed which comprises: (i) at least one disease-associated antigen which is capable of producing a T-cell response, wherein the disease-associated antigen is encapsulated in the nanoparticle; (ii) at least one adjuvant; and (iii) a dendritic cell targeting moiety which is attached to the outer surface of the nanoparticle. Use of the nanoparticle for treating diseases associated with abnormal cell growth or an infection is also disclosed.

Abstract: The present disclosure provides heteroarene-based drug derivatives having a “clickable” ketone group, as well as conjugates of said drug derivatives with targeting moieties capable of binding to extracellular antigens; and pharmaceutical compositions comprising them.

Abstract: Polymers useful for associating therewith oligonucleotides and for delivering the oligonucleotides into a cell, conjugates comprising these polymers and an oligonucleotide associated therewith, and compositions comprising same are provided. Also provided are uses of these conjugates in, for example, gene therapy, and particularly gene silencing. The disclosed polymers feature a PGA backbone, and amine-terminated pendant groups attached to at least 40% of the backbone units, and optionally further comprise alkyl pendant groups and/or other nitrogen-containing pendant groups attached to other one or more portions of the backbone units. The disclosed polymers can be cross-linked or can form a part of a block-copolymer.
