Pfenex Inc. Announces Research Study With Pfizer Inc.
MDRNA will be responsible for formulating Pfizer's oligonucleotides in DiLA2 formulations for in vivo preclinical evaluation to be performed at Pfizer. Additionally, MDRNA's research team will design and synthesize UsiRNAs directed against targets specified by Pfizer.
"We are extremely pleased to be working with Pfizer, a world leader in the pharmaceutical industry," said Michael French, President and CEO of MDRNA. "As Pfizer has made a commitment to the research and development of RNAi therapeutics, this is a significant opportunity for MDRNA to again demonstrate the broad capabilities of its world-class research team and proprietary drug discovery engine for RNAi-based therapeutics."
About UsiRNAs and Unlocked Nucleobase Analogs
A UsiRNA is a duplex siRNA containing at least one Unlocked Nucleobase Analog (UNA). In a UsiRNA, UNAs are non-nucleotide monomers and synthesized much like RNA in the construction of a double-stranded oligonucelotide for use as an RNAi-based therapeutic. In the case of the UsiRNA, UNA is substituted for specific nucleotides in both the guide and passenger strands. UsiRNAs are fully recognized by the cellular RNAi machinery, as demonstrated by their potent activity. MDRNA has also shown that substitution of UNA for specific RNA increases stability to nucleases, substantially reduces cytokine induction, and reduces passenger and guide strand-mediated off target effects. The high potency, and improved drug-like properties, associated with UsiRNAs provide the potential to greatly enhance RNAi-based therapeutics.
About the DiLA2 Delivery Platform
The DiLA2 Delivery Platform is MDRNA's proprietary platform for creating novel liposomal delivery systems based on di-alkylated amino acids (DiLA2). The DiLA2 Platform enables MDRNA to tailor the charge, linker length, and acyl chain characteristics to improve delivery of the liposomes to target tissue of interest. In vivo studies have demonstrated effective delivery in models of metabolic disease, cancer, and other diseases. DiLA2 based liposomes are well tolerated for repeat dose, and systemic and local administration. MDRNA is also utilizing condensing peptides to form peptide-siRNA nanoparticles to further increase the delivery efficiency of its DiLA2 delivery systems. In addition, the platform is designed to permit attachment of peptides and other targeting molecules for delivery to a variety of tissues, and thus provide for a diverse therapeutic portfolio.
About MDRNA, Inc.
MDRNA is a biotechnology company focused on the development and commercialization of therapeutic products based on RNA interference (RNAi). Our goal is to improve human health through the development of RNAi-based compounds and drug delivery technologies that together provide superior therapeutic options for patients. Over the past decade, we have developed substantial capabilities in molecular biology, cellular biology, amino acid chemistry, peptide chemistry, pharmacology and bioinformatics, which we are applying to a wide range of RNAi technologies and delivery approaches. These capabilities plus the in-licensing of key RNAi-related intellectual property have rapidly enabled us to become a leading RNAi-based therapeutics company with a pre-clinical pipeline in oncology. Through our capabilities, expertise and know-how, we are incorporating multiple RNAi technologies as well as peptide- and liposome-based delivery approaches into a single integrated drug discovery platform that will be the engine for our clinical pipeline as well as a versatile platform for establishing broad therapeutic partnerships with biotechnology and pharmaceutical companies. We are also investing in new technologies that we expect to lead to safer and more effective RNAi-based therapeutics while aggressively building upon our broad and extensive intellectual property estate. By combining broad expertise in siRNA science with proven delivery platforms and a strong IP position, MDRNA is well positioned as a leading RNAi-based drug discovery and development company.
