SHANGHAI, Nov. 18, 2024 /PRNewswire/ -- Rona Therapeutics, a leader in innovative RNA-based therapies, today presented positive results from the Phase 1 clinical trial of RN0191 at the American Heart Association's (AHA) Annual Scientific Sessions in Chicago, IL, November 16th, 2024. RN0191 is a proprietary GalNAc conjugated PCSK9 siRNA designed to significantly lower low-density lipoprotein cholesterol (LDL-C) and other lipid parameters.
The Ph1 study was a randomized, single-dose ascending, placebo-controlled study to evaluate safety, tolerability, pharmacokinetics and pharmacodynamics in healthy subjects with elevated LDL-C. The demographics included adults aged 18 to 60 years, spanning a BMI range of 19-30 kg/m2. All results are based on data in the database as of Oct. 14, 2024. A total of 32 subjects were randomized and treated with RN0191 from 60mg to 600mg, respectively. The baseline LDL-C mean level was ranging from 110-130 mg/dL.
After a single-dose subcutaneous injection, RN0191 showed a favorable safety profile with no serious adverse events and only mild, transient adverse events reported across all dose- levels. Dose-dependent, significant and durable changes in PCSK9, LDL-C and other lipid parameters were observed (see table below).
