Welcome to Alnylam

Alnylam is developing an entirely new class of medicines based on the breakthrough discovery in biology known as RNA interference, or RNAi. Alnylam believes that RNAi therapeutics are a promising approach to silence disease-causing genes, and represent an opportunity to transform the treatment of many diseases.

Alnylam 2020

Alnylam 2020

In January 2015, we launched our “Alnylam 2020” guidance for the advancement and commercialization of RNAi therapeutics as a whole new class of innovative medicines.  Specifically, by the end of 2020, we expect to achieve a company profile with 3 marketed products, 10 RNAi therapeutic clinical programs – including 4 in late stages of development – across 3 Strategic Therapeutic Areas (STArs).  Our 3 STArs include: Genetic Medicines, RNAi therapeutics for the treatment of rare diseases; Cardio-Metabolic Disease, RNAi therapeutics for the treatment of unmet needs in dyslipidemia, hypertension, diabetes, and non-alcoholic steatohepatitis (NASH); and Hepatic Infectious Disease, RNAi therapeutics for the treatment of infectious diseases with liver involvement.  “Alnylam 2020” marks our expected transition from a late-stage clinical development company to a multi-product commercial-stage company with a robust and sustainable development pipeline – a profile that we believe has rarely been achieved in the biopharmaceutical industry.


Pipeline Growth Strategy for RNAi Therapeutics in Three Strategic Therapeutic Areas, or “STArs”

Pipeline Growth Strategy for RNAi Therapeutics in Three Strategic Therapeutic Areas, or “STArs”

In December 2014, we announced a pipeline growth strategy for development and commercialization of RNAi therapeutics across three Strategic Therapeutic Areas (STArs): Genetic Medicines, Cardio-metabolic Disease, and Hepatic Infectious Disease.  The strategy builds on our progress in the advancement of RNAi therapeutics, including our “Enhanced Stabilization Chemistry” (ESC)-GalNAc conjugate technology, as a modular and reproducible platform for discovery of innovative medicines.  The three STArs will remain focused on liver-expressed and genetically validated or pathogen-derived disease targets, with biomarkers for assessment of clinical activity early in Phase 1 trials.  Across our three STArs, we believe that we can address major unmet needs in a wide range of diseases with high-impact, differentiated medicines, and continue to build what we believe to be one of the most robust pipelines in biotech.  By executing on this strategy, we believe we have the potential to make a meaningful difference in the lives of patients, and maximize value for shareholders.




Positive Initial Clinical Data from Phase 1 Trial with ALN-PCSsc

Positive Initial Clinical Data from Phase 1 Trial with ALN-PCSsc

Alnylam and The Medicines Company reported positive initial results from the ongoing Phase 1 clinical trial with ALN-PCSsc, an investigational RNAi therapeutic targeting PCSK9 for the treatment of hypercholesterolemia.  Subcutaneous administration of ALN-PCSsc resulted in an up to 83% lowering of LDL-C, with an up to 64 ± 5% mean maximum reduction, comparable to published results for anti-PCSK9 monoclonal antibodies (Zhang XL., et al., BMC Med, 2015).  Similar reductions in LDL-C were seen in patients on and off concomitant statin therapy.  The effects of ALN-PCSsc were highly durable, with clinically significant and clamped reductions in LDL-C maintained for over 140 days, supportive of a once-quarterly and possibly bi-annual subcutaneous dose regimen. Maximal lowering effects on LDL-C were consistently achieved at a dose of 300 mg associated with a low injection volume of 1.5 mL. Importantly, ALN-PCSsc was generally well tolerated with no clinically significant adverse events to date.

2015 Summer RNAi Roundtable Series

2015 Summer RNAi Roundtable Series

We are hosting a series of online “RNAi Roundtables” during July, August and September, at which Alnylam scientists and key clinical collaborators will review recent progress in many of the company’s development-stage pipeline programs and discuss the related disease areas.

Positive Interim Clinical Results from Ongoing Phase 1 Trial of ALN-AT3 for the Treatment of Hemophilia and Rare Bleeding Disorders

Positive Interim Clinical Results from Ongoing Phase 1 Trial of ALN-AT3 for the Treatment of Hemophilia and Rare Bleeding Disorders

We presented positive interim clinical data from our ongoing Phase 1 study for ALN-AT3, a subcutaneously administered, investigational RNAi therapeutic targeting antithrombin (AT) for the treatment of hemophilia and rare bleeding disorders. Data were presented at the International Society on Thrombosis and Haemostasis (ISTH) 2015 Congress held June 20 – 25, 2015. New clinical results from 12 subjects with severe hemophilia show that subcutaneous administration of ALN-AT3 achieved potent and dose-dependent knockdown of AT of up to 86%. AT knockdown was highly durable, with effects lasting over two months after the last dose, supporting further evaluation of a once-monthly subcutaneous dose regimen. In addition, AT knockdown was associated with statistically significant increases in thrombin generation with a mean increase of up to 350% and marked improvements in whole blood clotting; these results demonstrate a re-balancing of hemostasis in severe hemophilia subjects. Furthermore, in an exploratory post-hoc analysis, a reduced frequency of bleeding was observed at higher AT knockdown levels with a maximum bleed-free interval of 114 days. Very importantly, ALN-AT3 continues to be generally well tolerated.

Positive Initial Phase 1/2 Clinical Results for ALN-CC5 for the Treatment of Complement-Mediated Diseases

Positive Initial Phase 1/2 Clinical Results for ALN-CC5 for the Treatment of Complement-Mediated Diseases

We reported positive initial clinical results from our Phase 1/2 trial of ALN-CC5, an investigational RNAi therapeutic targeting complement component C5 for the treatment of complement-mediated diseases. The new clinical data are being presented at the 20th Congress of the European Hematology Association (EHA) held June 11 – 14, 2015. Initial study results from 12 healthy volunteer subjects showed that subcutaneous administration of a single dose of ALN-CC5 resulted in potent, dose-dependent, durable, and statistically significant knockdown of serum C5 of up to 96%. In addition, single dose administration of ALN-CC5 achieved inhibition of serum complement activity of up to 92%, including an up to 61% inhibition of serum hemolytic activity. Further, ALN-CC5 has been found to be generally well tolerated to date.
