CAMBRIDGE, Mass. & PARSIPANY, N.J.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq:ALNY), the leading RNAi therapeutics company, and The Medicines Company (Nasdaq:MDCO), a leading biopharmaceutical development and cardiovascular product company, today announced that results from the Phase 1 study of inclisiran (in-CLEE-si-ran), the recommended International Nonproprietary Name (INN) for ALN-PCSsc, were published in The New England Journal of Medicine (NEJM). Inclisiran is an investigational RNAi therapeutic targeting PCSK9 – a genetically validated protein regulator of LDL receptor metabolism – being developed for the treatment of hypercholesterolemia. The paper can be found online here.
Results from the study showed doses ≥300 mg (single or multiple doses) significantly reduced PCSK9 and LDL cholesterol for at least 6 months. Moreover, inclisiran was found to be generally well tolerated.
"The published findings from our Phase 1 trial with inclisiran add to the clinical evidence supporting PCSK9 as a therapeutic target for significantly lowering LDL cholesterol, as well as the ability of RNAi therapeutic candidates to inhibit synthesis of liver-derived target proteins in a potent and durable manner,” said Akshay Vaishnaw, M.D., Ph.D., Executive Vice President of R&D and Chief Medical Officer of Alnylam. “We believe that inclisiran represents an innovative and differentiated approach for the treatment of hypercholesterolemia.”
Inclisiran is currently being studied in the ORION-1 Phase 2 study by The Medicines Company. With more than 500 patients enrolled, ORION-1 is the largest study of a GalNAc-siRNA conjugate to date. The Medicines Company recently announced positive top-line results from the day 90 interim analysis of the Phase 2 study demonstrating significant and durable LDL-C reduction that validates the potential for a triannual or biannual dosing regimen. Top-line results also showed that inclisiran was generally well tolerated, with no evidence of drug-related elevations of liver enzymes, neuropathy adverse events, or changes in renal function. The Medicines Company plans to present complete interim results from the ongoing study in a Late-Breaking Clinical Trial Session at the American Heart Association (AHA) Scientific Sessions on November 15, 2016.
“We look forward to presenting the interim results of the ORION-1 Phase 2 data at AHA this week including Day 90 follow-up results for all 501 patients and a preliminary analysis of Day 180 follow-up for up to 200 patients,” said David Kallend, MBBS, Vice President and Global Medical Director at The Medicines Company. “Based on the strong results from the Phase 1 study, we hope to further elucidate the hypothesis of triannual or biannual dosing of inclisiran with the ORION-1 results.”
The NEJM publication highlights key results from the Phase 1 clinical trial of inclisiran, including safety and pharmacodynamic measures (PCSK9, LDL cholesterol, exploratory lipid parameters).
In the single-ascending-dose (SAD) phase, pharmacodynamic measures showed:
- Doses ≥300 mg reduced PCSK9 at day 84 (up to a least-squares mean (LSM) reduction of 74.5%);
- Doses ≥100 mg reduced LDL cholesterol at day 84 (up to a LSM reduction of 50.6%);
- Reductions in PCSK9 and LDL cholesterol were maintained at day 180 with little variation over the 6-month period for doses ≥300 mg.
In the multiple-dose (MD) phase, pharmacodynamic measures showed:
- Reduced PCSK9 (up to a LSM reduction of 83.8%) and LDL cholesterol (up to a LSM reduction of 59.7%) at day 84;
- Levels of PCSK9 and LDL cholesterol remained reduced in all the inclisiran cohorts at day 196.
Safety and side effect profile evaluations showed:
- Inclisiran was generally well tolerated following single and multiple subcutaneous dose administration;
- No serious adverse events (SAEs) or discontinuations due to AEs were reported;
- All observed adverse events (AEs) were mild or moderate in severity;
- There was one Grade 3 GGT elevation considered related to statin therapy.
The lead development responsibility for inclisiran transitioned from Alnylam to The Medicines Company in August 2015. The two companies are now working to advance inclisiran in the ORION development program, a comprehensive global clinical development plan designed to support regulatory approval and market access worldwide.
About the Inclisiran Phase 1 Study
The Phase 1 trial of inclisiran was conducted in the U.K. as a randomized, single-blind, placebo-controlled, single ascending- and multi-dose, subcutaneous dose-escalation study. The study enrolled 69 volunteer subjects with elevated baseline LDL-C (≥ 100 mg/dL), with subjects randomized 3:1, drug: placebo. The study was performed in two phases: a single ascending dose (SAD) phase and a multiple dose (MD) phase. The MD phase also included subjects both on and off stable doses of statin co-medication. The primary objective of the Phase 1 study was to evaluate the safety, side effect profile, and pharmacodynamics effects of inclisiran.
Hypercholesterolemia is a condition characterized by very high levels of cholesterol in the blood which is known to increase the risk of coronary artery disease, the leading cause of death in the U.S. Some forms of hypercholesterolemia can be treated through dietary restrictions, lifestyle modifications (e.g., exercise and smoking cessation) and medicines such as statins. However, a large proportion of patients with hypercholesterolemia are not achieving adequate LDL-C levels with currently available therapies such as statins, including genetic familial hypercholesterolemia (FH) patients, acute coronary syndrome patients, high-risk patient populations (e.g., patients with coronary artery disease, diabetes, symptomatic carotid artery disease, etc.) and other patients that are statin intolerant. Severe forms of hypercholesterolemia are estimated to affect more than 500,000 patients worldwide, and as a result, there is a significant need for novel therapeutics to treat patients with hypercholesterolemia whose disease is inadequately managed by existing therapies.
About GalNAc Conjugates and Enhanced Stabilization Chemistry (ESC)-GalNAc Conjugates
GalNAc-siRNA conjugates are a proprietary Alnylam delivery platform and are designed to achieve targeted delivery of RNAi therapeutics to hepatocytes through uptake by the asialoglycoprotein receptor. Alnylam's Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate technology enables subcutaneous dosing with increased potency and durability, and a wide therapeutic index. This ESC-GalNAc-conjugate delivery platform is being employed in nearly all of Alnylam's pipeline programs, including inclisiran and several other programs in clinical development.
RNAi (RNA interference) is a revolution in biology, representing a breakthrough in understanding how genes are turned on and off 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, thereby preventing disease-causing proteins from being made. RNAi therapeutics have the potential to treat disease and help patients in a fundamentally new way.
