Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, is hosting a virtual R&D Day today. During the event, the Company plans to showcase its R&D progress, including its product and pipeline goals for 2022, focused on continued commercial execution of four RNAi therapeutic products, the potential launch of its fifth product, as well as advancement of early-, mid- and late-stage investigational programs.

“At Alnylam, we are excited about the opportunity for RNAi therapeutics in rare and common diseases utilizing liver and extrahepatic delivery to realize the greatest potential for this new class of medicines in human health,” said Akshay Vaishnaw, M.D., Ph.D., President of R&D at Alnylam. “Our annual R&D Day will feature updates across our pipeline, including deep dive discussions on RNAi therapeutic opportunities in ATTR amyloidosis and hypertension. In addition, we’ll highlight an exciting new program opportunity for vutrisiran in an inherited retinopathy, Stargardt Disease, and will describe additional new programs that have the potential to provide a foundation for sustainable innovation. Finally, we’ll highlight the strong progress we have made in extrahepatic delivery of RNAi therapeutics that we believe could have broad applicability across human disease. These new advances are all a part of building Alnylam for the future and will play a critical role in helping us achieve our ‘Alnylam P5x25’ goals.”

Stargardt Disease: Promising New Opportunity for Vutrisiran

Alnylam will discuss a new near-term opportunity for vutrisiran as an investigational RNAi therapeutic for the potential treatment of Stargardt Disease. Stargardt Disease is a rare, inherited form of blindness caused by accumulation of toxic vitamin A metabolites in the retina which leads to central vision loss. It is a leading cause of blindness from inherited retinal diseases in children, and almost all people affected by this disease become legally blind as adults. Stargardt Disease is estimated to affect about 65,000 people in the U.S. and EU (incidence of approximately 1 in 8,000-10,000), with high unmet medical need and no approved treatments.

Transthyretin (TTR) functions as a transporter of vitamin A in the blood. It forms a complex with retinol binding protein (RBP4) to deliver vitamin A to extrahepatic tissues, including the eye. In healthy individuals, the protein ABCA4 acts as a transporter for vitamin A in the eye, ensuring that toxic vitamin A metabolites do not accumulate in the retina. In contrast, patients with Stargardt Disease have an inherited defect in ABCA4. As a result, toxic vitamin A metabolites accumulate in the retina as lipofuscin, triggering degeneration of macular rods and cones, leading to central vision loss and eventually blindness in most patients.

The Company believes that RNAi-mediated serum TTR reduction with vutrisiran has the potential to reduce RBP4-mediated delivery of vitamin A to the eye and could prevent lipofuscin accumulation and resulting macular damage. Data from the HELIOS-A Phase 3 study of vutrisiran have demonstrated a high correlation between serum TTR reduction and vitamin A reduction, supporting the therapeutic hypothesis.

Alnylam plans to initiate a Phase 3 study in patients with Stargardt Disease in late 2022, following regulatory alignment.

Sustainable Innovation Driven by Platform Advances and Human Genetics

Alnylam’s continued investment in scientific innovation has yielded a new technology with the potential to simultaneously silence two unique gene transcripts using a single chemical entity. The Company believes that this platform, called GEMINI (formerly referred to as BIS technology), could have potential applications in cardiometabolic, CNS, oncologic, and viral diseases. The first investigational compound from this platform, GEMINI-CVR, targets two genes implicated in cardiovascular disease: Angiopoietin-like protein 3 (ANGPTL3) – a genetically validated target involved in lipid metabolism – and angiotensinogen, a pharmacologically validated target involved in blood pressure regulation. Reducing these two highly validated risk factors could reduce cardiovascular morbidity and mortality in at-risk populations with tonic control of both risk factors providing the potential for high adherence with a vaccine-like medicine administered by subcutaneous injection biannually or annually. The Company plans to identify a Development Candidate for the GEMINI-CVR program in 2023.

In addition, the Company will present new human genetics data from the UK BioBank (UKBB) that led to the identification of a liver-expressed target, referred to as “Gene X,” shown to be highly associated with metabolic syndrome and visceral adiposity. RNAi-mediated knockdown of Gene X is predicted to have broad beneficial effects on all facets of metabolic syndrome with potential reductions in the risk of Type 2 diabetes and coronary artery disease. IND-enabling work is ongoing to potentially allow for a biannual or annual subcutaneous dose regimen with an IND filing possible in 2023.

Opportunities with RNAi Therapeutics Beyond the Liver

Finally, Alnylam will present an update on its programs involving extrahepatic delivery of investigational RNAi therapeutics, including opportunities for CNS and ocular diseases. The disclosed CNS and ocular programs include:

  • ALN-APP, targeting amyloid precursor protein (APP) in development for the treatment of Alzheimer’s Disease;
  • ALN-HTT, targeting huntingtin protein, including exon 1, in development for the treatment of Huntington’s Disease (HD);
  • A new program, ALN-SOD targeting SOD-1, in development for the treatment of SOD-1-Specific Amyotrophic Lateral Sclerosis (ALS); and,
  • A new program in glaucoma.

Alnylam is advancing its CNS and ocular disease programs in a 50-50 collaboration with Regeneron.

Alnylam will also present new data on delivery of RNAi therapeutics to additional tissues, including muscle, heart, and adipose, and an initial oncology program targeting hepatocellular carcinoma.

About RNAi

RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines, known as RNAi therapeutics, is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam's RNAi therapeutic platform, function upstream of today’s medicines by potently silencing messenger RNA (mRNA) – the genetic precursors – that encode for disease-causing or disease pathway proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.
