CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, announced today that the first patient has been dosed in the Company’s Phase 1 study of ALN-AGT, an investigational RNAi therapeutic targeting angiotensinogen (AGT) for the treatment of hypertension in high unmet need populations, including patients with resistant or refractory hypertension, chronic kidney disease or heart failure. The Company expects to report initial results in late 2019.
“We are pleased to have initiated dosing in this Phase 1 study with the goal of evaluating the safety and preliminary pharmacokinetic and pharmacodynamic activity of ALN-AGT in patients with hypertension,” said Lauren Melton, Senior Director, Program Leader, ALN-AGT program at Alnylam. “We believe RNAi-mediated angiotensinogen silencing represents a novel and targeted approach with the potential to offer robust and highly durable control of blood pressure for patients with resistant or refractory hypertension.”
The Phase 1 study is a multi-center, randomized, double-blind, placebo-controlled trial designed to evaluate the safety, tolerability, pharmacokinetic, and pharmacodynamic effects of subcutaneously administered ALN-AGT in patients with essential hypertension. The study will be conducted in four parts: Part A: single ascending dose phase in hypertensive patients; Part B: single dose in hypertensive patients with controlled salt intake; Part C: multi-dose phase in hypertensive patients; and Part D: multi-dose phase in hypertensive patients who are obese. In Parts C and D, once daily oral doses of irbesartan (angiotensin II receptor blocker) will be used as the active comparator. Patients will be randomized 2:1 ALN-AGT to placebo or ALN-AGT to irbesartan. The planned enrollment for this study, including optional cohorts, is up to 168 patients.
ALN-AGT is an investigational, subcutaneously administered RNAi therapeutic targeting angiotensinogen (AGT) in development for the treatment of hypertension in high unmet need populations. ALN-AGT utilizes Alnylam's Enhanced Stabilization Chemistry Plus (ESC+) GalNAc-conjugate technology, which enables subcutaneous dosing with increased selectivity and a wide therapeutic index. The safety and efficacy of ALN-AGT have not been evaluated by the FDA, EMA or any other health authority.
Hypertension is a complex multifactorial disease clinically defined as a systolic blood pressure of above 130 or a diastolic blood pressure of greater than 80 mmHg. Approximately 47 percent of U.S. adults live with hypertension with more than half of patients on medication remaining above the blood pressure target level. Despite the availability of antihypertensive medications, there remains an unmet medical need, particularly given the poor rates of adherence to existing therapies and peak and trough effects. In particular, there are a number of high unmet need settings where novel approaches to hypertension are warranted, including resistant and refractory hypertension, chronic kidney disease, and heart failure.
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 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.
About Alnylam Pharmaceuticals
Alnylam (Nasdaq: ALNY) is leading the translation of RNA interference (RNAi) into a new class of innovative medicines with the potential to transform the lives of people afflicted with rare genetic, cardio-metabolic, hepatic infectious, and central nervous system/ocular diseases. Based on Nobel Prize-winning science, RNAi therapeutics represent a powerful, clinically validated approach for the treatment of diseases with high unmet need. ONPATTRO® (patisiran) is the first-ever RNAi therapeutic approved by the U.S. FDA for the treatment of the polyneuropathy of hereditary transthyretin-mediated (hATTR) amyloidosis in adults and by the EMA for the treatment of hATTR amyloidosis in adults with stage 1 or stage 2 polyneuropathy. Alnylam has a deep pipeline of investigational medicines, including six product candidates in Phase 3 studies. Looking forward, Alnylam will continue to execute on its "Alnylam 2020" strategy of building a multi-product, commercial-stage biopharmaceutical company with a sustainable pipeline of RNAi-based medicines to address the needs of patients who have limited or inadequate treatment options. Headquartered in Cambridge, MA, Alnylam employs over 1,200 people worldwide.
