We presented pre-clinical data with ALN-HBV, an RNAi therapeutic targeting the hepatitis B virus (HBV) genome for the treatment of HBV infection, at the TIDES 2014 meeting held May 12 – 15 in Providence, Rhode Island. Specifically, we reported significant, multi-log reductions in HBV surface antigen (HBsAg) and HBV viral titers, and showed evidence for an immune-mediated therapeutic effect in chronically infected chimpanzees.

We are presenting key scientific data on our Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate delivery platform at the TIDES 2014 meeting held May 12 – 15, 2014 in Providence, Rhode Island. This technology enables subcutaneous dosing of RNAi therapeutics with increased potency and durability, and a wide therapeutic index.  Data show that chemical modifications of siRNA that enhance in vitro stability result in higher liver exposure in vivo and lead to a significantly increased potency and durability of effect in pre-clinical studies. As compared with the “standard template chemistry” (STC)-GalNAc-conjugate approach used in our ALN-TTRsc program for the treatment of transthyretin (TTR) cardiac amyloidosis, ESC-GalNAc-siRNA conjugates demonstrated a 10-fold increased potency in non-human primate (NHP) studies, and a durability of effect that supports once-monthly or possibly even less frequent subcutaneous dosing regimens.

We presented new pre-clinical data supporting the advancement of a Development Candidate (DC) for ALN-AAT, an RNAi therapeutic targeting alpha-1 antitrypsin (AAT) for the treatment of AAT deficiency-associated liver disease. Data were presented in a Late-Breaking Abstract Session at Digestive Disease Week (DDW), held May 3 – 6, 2014 in Chicago. As previously presented at the 64th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD, “The Liver Meeting”) in November 2013 and as updated at DDW, studies were performed in transgenic mice overexpressing the human Z-AAT protein. Subcutaneous administration of a GalNAc-siRNA targeting AAT led to rapid, potent, dose-dependent, and durable knockdown of AAT of greater than 95%, as well as a significant reduction in fibrosis and the incidence of liver tumors.

We have presented new pre-clinical data from our growing pipeline of RNAi therapeutics for the treatment of cardiovascular metabolic disease, including ALN-PCSsc targeting PCSK9 for the treatment of hypercholesterolemia, and a newly named program, ALN-AC3 targeting apolipoprotein C-III (apoCIII) for the treatment of hypertriglyceridemia.  The data were presented in an oral presentation at the Arteriosclerosis, Thrombosis and Vascular Biology (ATVB) 2014 Scientific Sessions held May 1-3, 2014 in Toronto, Ontario.

We have presented pre-clinical data with RNAi therapeutics targeting TTR for the treatment of TTR-mediated amyloidosis (ATTR).  These data were presented at the International Symposium on Amyloidosis (ISA) held April 27 – May 1, 2014.  These data showed that the degree of TTR knockdown in a mouse disease model was highly correlated with regression of TTR tissue deposits.  Further, comparative studies performed with the TTR stabilizer tafamidis and a TTR-specific antisense oligonucleotide (ASO) showed RNAi therapeutics targeting TTR to have superior pharmacologic profiles.

We have reported positive initial data from our Phase 2 open-label extension (OLE) study with patisiran (ALN-TTR02), an RNAi therapeutic targeting transthyretin (TTR) in development for the treatment of TTR-mediated amyloidosis (ATTR).  Data were presented at the International Symposium on Amyloidosis, held April 27 – May 1, 2014.  Preliminary results showed that multiple doses of patisiran achieved sustained knockdown of serum TTR protein levels at the approximately 80% target level through 168 days.  Moreover, OLE results showed a favorable tolerability profile with up to eight doses administered.  These data provide the first clinical evidence of sustained RNAi-mediated TTR knockdown in FAP patients beyond two doses of patisiran.     [spotlight-link icon="release" href="http://investors.alnylam.com/releasedetail.cfm?ReleaseID=842968" type=" "] Read our press release[/spotlight-link] [spotlight-link icon="presentation" href="http://www.alnylam.com/web/assets/ALNY-Clinical-Update-Patisiran-Phase2-Trials-ISA2014.pdf" type="(0.8 MB PDF)"] View the patisiran Phase 2/OLE presentation [/spotlight-link] [spotlight-link icon="presentation" href="http://www.alnylam.com/web/assets/ALNY-FAP-NaturalHistoryStudy-ISA2014.pdf" type="(0.8 MB PDF)"] View the FAP Natural History Study presentation [/spotlight-link]

We presented new pre-clinical data on the pharmacology of GalNAc-siRNA conjugates at the 12th US-Japan Symposium on Drug Delivery Systems held December 16 – 20, 2013 in Lahaina, Maui, Hawaii. These new research findings describe the effects of long-term chronic dosing of GalNAc-siRNA conjugates on tissue drug levels and sustained target knockdown.

We presented pre-clinical data from three programs within our “Alnylam 5x15” RNAi therapeutic pipeline: ALN-AT3 for the treatment of hemophilia and rare bleeding disorders (RBD), ALN-CC5 for the treatment of complement-mediated diseases, and ALN-TMP for the treatment of β-thalassemia and iron overload disorders. These data were presented at the 55th Annual Meeting of the American Society of Hematology (ASH) held December 7 – 10 in New Orleans.

We presented new pre-clinical data with RNAi therapeutic programs for cardiovascular disease: ALN-PCSsc, an RNAi therapeutic targeting PCSK9 for the treatment of hypercholesterolemia; and ALN-ANG, an RNAi therapeutic targeting ANGPTL3 for the treatment of genetic forms of mixed hyperlipidemia and severe hypertriglyceridemia. These data were presented at the American Heart Association (AHA) Scientific Sessions held November 16 – 20, 2013 in Dallas, Texas. The data showed that subcutaneous administration of ALN-PCSsc led to an up to 95% knockdown of plasma PCSK9 and an up to 67% reduction of low density lipoprotein cholesterol (LDL-C) – in the absence of statin co-administration. In addition, new results for ALN-ANG demonstrated a greater than 95% reduction of triglycerides and greater than 85% reduction of LDL-C in a rodent model of mixed hyperlipidemia.

We presented positive data from our Phase II clinical trial of patisiran (ALN-TTR02) for the treatment of transthyretin-mediated amyloidosis (ATTR) at the International Symposium on Familial Amyloidotic Polyneuropathy, November 10 – 13, 2013. Results showed that multiple doses of patisiran led to robust and statistically significant knockdown of serum TTR protein levels of up to 96%, with mean levels of TTR knockdown exceeding 85%.  Knockdown of TTR, the disease-causing protein in ATTR, was found to be rapid, dose dependent, and durable, and similar activity was observed toward both wild-type and mutant protein.   In addition, patisiran was found to be generally safe and well tolerated in this study.
