siRNA clinical trials: state of the art With the emergence of siRNA-based nanomedicine as a powerful therapeutic strategy for cancers, seven of these therapeutics have now advanced to clinical trials. Carriers of siRNA therapeutics include transferrin-modified cyclodextrin (CALAA-01, Arrowhead Research Corporation, CA, USA), in vivo jetPEI (SNS01-T; Sevion Technologies, NJ, USA), cationic liposomes (ALN-VSP02, Alnylam Pharmaceuticals, MA, USA; TKM080301, Tekmira Pharmaceuticals, Burnaby, Canada… 
Targeting siRNAs in cancer drug delivery
Systemic Delivery of Folate-PEG siRNA Lipopolyplexes with Enhanced Intracellular Stability for In Vivo Gene Silencing in Leukemia.
Protection of small interfering RNA (siRNA) against degradation and targeted delivery across the plasma and endosomal membranes to the final site of RNA interference (RNAi) are major aims for the
Co-delivery of pretubulysin and siEG5 to EGFR overexpressing carcinoma cells.
Advanced Strategies in Immune Modulation of Cancer Using Lipid-Based Nanoparticles
TLDR
The use of nanoparticle-based system for immunotherapy is a promising strategy that can simultaneously target multiple pathways with the same kinetics to enhance antitumor response.
Variable Heavy Chain Domain Derived from a Cell-Penetrating Anti-DNA Monoclonal Antibody for the Intracellular Delivery of Biomolecules
TLDR
Results indicate that the recombinant 2C10 VH domain could be applied as an efficient vehicle capable of delivering valuable biomolecule into the cytoplasm or cell nuclei for clinical uses.
Immunomodulation of hematological malignancies using oligonucleotides based-nanomedicines.
Efficient Shielding of Polyplexes Using Heterotelechelic Polysarcosines
TLDR
Polysarcosine is a promising alternative for the shielding of non-viral, lipo-cationic polyplexes and showed enhanced blood circulation times in bioimaging studies compared to unshielded polyplexe and similar to PEG-shieldedpolyplexes.

TLDR
Polysarcosine is a promising alternative for the shielding of non-viral, lipo-cationic polyplexes and showed enhanced blood circulation times in bioimaging studies compared to unshielded 30 polyplexe and similar to PEG-shieldedpolyplexes.

TLDR
A novel double modulation strategy in cancer treatment is proposed, in which chemotherapy enhances intratumoral siRNA delivery and the delivered siRNA enhances the chemosensitivity of tumors.
Evidence of RNAi in humans from systemically administered siRNA via targeted nanoparticles
TLDR
Evidence is provided of inducing an RNAi mechanism of action in a human from the delivered siRNA and the presence of an mRNA fragment that demonstrates that siRNA-mediated mRNA cleavage occurs specifically at the site predicted for anRNAi mechanism from a patient who received the highest dose of the nanoparticles.
