In addition to new data on the Company's ESC+ platform, Alnylam scientists and collaborators presented additional pre-clinical findings showing continued leadership in RNAi technologies and delivery. First, Alnylam scientists presented further advances toward optimizing the Company's GalNAc-siRNA conjugate platform. These included studies to further improve the mechanistic understanding of conjugate duration of activity as well as the development of advanced ESC designs with significantly improved metabolic stability and in vivo efficacy. Further, new data on Alnylam's Reversir™ platform were presented. Specifically, optimizations were implemented that enable rapid reversal of siRNA-mediated mRNA silencing, providing the means to fine-tune the pharmacology of GalNAc-siRNA conjugates. Finally, pre-clinical data demonstrating extra-hepatic siRNA delivery, involving Centyrins, a novel class of highly stable FN3 domain proteins, were also presented as part of a research collaboration with Janssen Research & Development, LLC. Centyrin-siRNA conjugates showed excellent cross-tumor penetration and mediated robust target knockdown in a mouse xenograft tumor model. Also, the generalizability of this approach was demonstrated in vitro using Centyrins for a number of different receptors and gene targets.These results can be viewed on the Capella section of the Alnylam website. About RNAi RNAi (RNA interference) is a revolution in biology, representing a breakthrough in understanding protein synthesis in cells, and a completely new approach to drug discovery and development. Its discovery has been heralded as "a major scientific breakthrough that happens once every decade or so," and represents one of the most promising and rapidly advancing frontiers in biology and drug discovery today which was awarded the 2006 Nobel Prize for Physiology or Medicine. RNAi is a natural process of gene silencing that occurs in organisms ranging from plants to mammals. By harnessing the natural biological process of RNAi occurring in our cells, the creation of a major new class of medicines, known as RNAi therapeutics, is on the horizon. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam's RNAi therapeutic platform, target the cause of diseases by potently silencing specific mRNAs, with the goal of preventing disease-causing proteins from being made.
About Reversir™Alnylam's Reversir platform utilizes GalNAc-conjugated single-stranded high affinity oligonucleotides complementary to the guide strand of the siRNA to rapidly reverse RNAi-mediated silencing of target transcripts. Reversir provides the means to fine-tune the pharmacology of GalNAc-siRNA conjugates by enabling control of duration of silencing. About Alnylam Pharmaceuticals Alnylam (Nasdaq: ALNY) is leading the translation of RNA interference (RNAi) into a whole new class of innovative medicines with the potential to transform the lives of patients who have limited or inadequate treatment options. Based on Nobel Prize-winning science, RNAi therapeutics represent a powerful, clinically validated approach for the treatment of a wide range of debilitating diseases. Founded in 2002, Alnylam is delivering on a bold vision to turn scientific possibility into reality, with a robust discovery platform and deep pipeline of investigational medicines, including four product candidates that are in late-stage development. Looking forward, Alnylam will continue to execute on its "Alnylam 2020" strategy of building a multi-product, commercial-stage biopharmaceutical company with a sustainable pipeline of RNAi-based medicines.
