CAMBRIDGE, Mass. / Dec 13, 2023 / Business Wire / 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 and platform innovation, as well as its product and pipeline goals for 2024, including continued commercial execution of four RNAi therapeutic products and the advancement of early-, mid-, and late-stage investigational programs.
“Alnylam continues to drive the next wave of RNAi therapeutics that is changing medicine, with a sustainable innovation engine generating a robust pipeline and a multi-product commercial portfolio setting the stage for the future. We expect our track record of strong pipeline and commercial execution to continue through the end of 2025 and beyond,” said Akshay Vaishnaw, M.D., Ph.D., Chief Innovation Officer of Alnylam. “As we look ahead to the next frontier of RNAi therapeutic innovation, we are excited to be presenting promising results that speak to our ambition to reach many new tissues, with new data on delivery to the central nervous system, adipose tissue, muscle, and tumors. We believe this progress—with nine or more Alnylam proprietary INDs planned by the end of 2025—will help build our pipeline to enable sustainable future growth and advance us toward achieving our ‘Alnylam P5x25’ goals of becoming a top-tier biotech company.”
Novel Extrahepatic Delivery Systems Extend Alnylam’s Leadership in RNAi Platform Innovation
Alnylam scientists will present new preclinical findings demonstrating RNAi-mediated knockdown of targets expressed in adipose and muscle. The data provide evidence for best-in-class delivery to these tissues using subcutaneous administration, with potent and sustained knockdown of specific genes. The Company is progressing candidates that employ the new delivery technology toward Development Candidate selection in 2024.
The Company will also share preclinical data demonstrating systemic delivery of an RNAi therapeutic across the blood-brain barrier to the central nervous system (CNS). The results, while early, have the potential to broaden applications of RNAi therapeutics in the CNS by eliminating the need for direct administration (i.e., intrathecally).
Next Wave of RNAi Therapeutics Fuel Robust Clinical Pipeline
Alnylam scientists will present new genetically validated targets for rare, specialty, and prevalent diseases, including for cholestatic liver diseases, a range of bleeding disorders, obesity, and type 2 diabetes mellitus (T2DM). By the end of 2025, the Company plans to file Investigational New Drug (IND) applications for at least nine new Alnylam-led RNAi programs, including five for targets expressed in the liver, two for the CNS, and one each for adipose tissue and muscle. The Company also anticipates that INDs will be filed for at least six additional programs led by partners during this timeframe.
New Positive Phase 1 Data Reinforce Strength of Organic Product Engine
Alnylam scientists will present positive initial results from Phase I clinical trials for ALN-TTRsc04, in development for the treatment of ATTR amyloidosis, and ALN-KHK, in development for the treatment of T2DM. In addition, Alnylam will share an update on delivery advances driving ALN-BCAT, which will soon begin clinical testing in patients with hepatocellular carcinoma (HCC).
ALN-TTRsc04 Phase 1 Study
ALN-TTRsc04 is an investigational RNAi therapeutic in development for the treatment of ATTR amyloidosis that utilizes Alnylam’s IKARIA technology and provides the potential for greater than 90% target gene silencing with once annual dosing. In the Phase 1 study in healthy volunteers, single 300 mg doses of ALN-TTRsc04 achieved rapid knockdown with a mean reduction of greater than 90% at Day 15. A peak mean TTR reduction of 97% was achieved at Day 29 and a mean TTR reduction of 93% was sustained at Day 180. At all dose levels evaluated to date, single doses of ALN-TTRsc04 have been well tolerated, with no adverse events deemed to be related to study drug by the investigator.
These initial results suggest the potential for ALN-TTRsc04 to offer over 90% TTR reduction with once annual dosing. The Phase 1 study is ongoing. Additional data will help inform selection of dose level and regimen for a Phase 3 study in ATTR amyloidosis with cardiomyopathy, which the Company expects to start at or around year-end 2024.
ALN-KHK Phase 1 Study
In the Phase 1 study in overweight to obese healthy volunteers, single doses of investigational ALN-KHK at the highest dose cohort available resulted in a mean increase in fructose area under the curve to 3-fold relative to baseline levels measured at Day 85, providing clear evidence of target engagement. Decreases in circulating FGF21 levels were also observed, consistent with the known biology of KHK.
ALN-KHK was shown to be safe and well tolerated, with an encouraging safety profile supporting continued clinical development, and target engagement that suggests the potential for quarterly or less frequent dosing. The study is ongoing, and additional data from the two highest dose levels will enable dose selection for Part B, which will evaluate multiple doses of ALN-KHK in obese patients with T2DM.
ALN-BCAT Phase 1 Study
Alnylam scientists will also present promising preclinical data with ALN-BCAT, an investigational RNAi therapeutic targeting β-catenin for the treatment of HCC. The Wnt/β-catenin pathway is implicated in many human cancers, including HCC, a leading cause of cancer death worldwide.1 Alnylam announces today that it recently filed an IND application with ALN-BCAT and plans to initiate a Phase 1 study in early 2024. The study will evaluate the investigational drug’s potential both as a monotherapy and in combination with immunotherapy in patients with advanced disease. ALN-BCAT employs Alnylam’s advanced lipid nanoparticle (LNP) delivery technology termed “reLNP,” which provides improved tolerability due to enhanced biodegradability.
2024 Product and Pipeline Goals
Alnylam plans to provide guidance on 2024 combined net product revenue for ONPATTRO®, AMVUTTRA®, GIVLAARI®, and OXLUMO® with its fourth quarter and full year 2023 results.

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.
