[{"type":"text","content":"\n— Dose-Dependent Reductions in Serum Angiotensinogen and 24-hour Ambulatory Blood Pressure Were Sustained for Six Months After Single Doses of Zilebesiran —\n\n\n— Acceptable Safety Profile Supporting Further Development —\n\n\n CAMBRIDGE, Mass.--(BUSINESS WIRE)--\nAlnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, announced today that results from its Phase 1 study of zilebesiran, an investigational RNAi therapeutic targeting liver-expressed angiotensinogen (AGT) in development for the treatment of hypertension, were published in the New England Journal of Medicine (NEJM). The full manuscript is titled, “Zilebesiran, an RNA Interference Therapeutic Agent for Hypertension,” and will appear in the July 20, 2023 issue of NEJM. The key data reported in the publication showed that in the Phase 1 study, compared to placebo, zilebesiran was associated with dose-dependent reductions in serum AGT, achieving tonic blood pressure control with consistent and durable blood pressure reduction throughout a 24-hour period, sustained up to six months after single doses of ≥200 mg of zilebesiran. Zilebesiran also demonstrated an acceptable safety profile supporting continued clinical development; the most frequent treatment-related adverse events were mild, transient injection-site reactions.\n\n\n“Hypertension is the leading cause of premature death, cardiovascular disease, and chronic kidney disease worldwide, and the global prevalence is steadily increasing in parallel with population aging and secular trends in the prevalence of risk factors including obesity, physical inactivity, and unhealthy diet. Despite the availability of effective antihypertensive treatments, nearly half of patients with hypertension fail to achieve guideline-recommended blood pressure targets, leaving them at residual risk for myocardial infarction, stroke, kidney disease progression, and mortality. For clinicians, the challenge in optimizing treatment of hypertension is frequently compounded by poor adherence to prescribed medical therapy and substantial variability in blood pressure between office visits and over the 24-hour cycle,” said Akshay Desai, M.D., the lead author of the manuscript and Director of the Cardiomyopathy and Heart Failure Program in the Advanced Heart Disease Section of the Cardiovascular Division at Brigham ...
