Integrin-targeted nanocomplexes for tumour specific delivery and therapy by systemic administration

Nanoparticle formulations offer opportunities for tumour delivery of therapeutic reagents. The Receptor-Targeted Nanocomplex (RTN) formulation consists of a PEGylated, endosomally-cleavable lipid and an RGD integrin-targeting, endosomally-cleavable peptide. Nancomplexes self-assemble on mixing with... Full description

description: Nanoparticle formulations offer opportunities for tumour delivery of therapeutic reagents. The Receptor-Targeted Nanocomplex (RTN) formulation consists of a PEGylated, endosomally-cleavable lipid and an RGD integrin-targeting, endosomally-cleavable peptide. Nancomplexes self-assemble on mixing with plasmid DNA to produce nanoparticles of about 100 nm. The environmentally-sensitive linkers promote intracellular disassembly and release of the DNA. RTNs carrying luciferase genes were administered intravenously to mice carrying subcutaneous neuroblastoma tumours. Luciferase expression was much higher in tumours than in liver, spleen and lungs while plasmid biodistribution studies supported the expression data. Transfection in tumours was enhanced two-fold by integrin-targeting peptides compared to non-targeted nanocomplexes. RTNs containing the interleukin-2 (IL-2) and IL-12 genes were administered intravenously with seven doses at 48 h intervals and tumour growth monitored. Tumours...

Nanoparticle formulations offer opportunities for tumour delivery of therapeutic reagents. The Receptor-Targeted Nanocomplex (RTN) formulation consists of a PEGylated, endosomally-cleavable lipid and an RGD integrin-targeting, endosomally-cleavable peptide. Nancomplexes self-assemble on mixing with plasmid DNA to produce nanoparticles of about 100 nm. The environmentally-sensitive linkers promote intracellular disassembly and release of the DNA. RTNs carrying luciferase genes were administered intravenously to mice carrying subcutaneous neuroblastoma tumours.
