Официальное название

A Randomized, Double-blind, Placebo-controlled, Multiple Doses, Dose-escalation Phase 1 Clinical Trial to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of SRN001 in Healthy Korean and Caucasian Adult Males

Обзор

To evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of repeated doses of SRN001 in healthy adult volunteers.

Подробное описание

SRN001 is a novel small interfering RNA (siRNA) drug being developed to treat fibrosis using Self Assembled Micelle inhibitory ribonucleic acid (SAMiRNA™) technology. Amphiregulin (AREG) is a growth factor involved in fibroblast proliferation and myofibroblast transformation which is the hallmark of fibrosis in lung and kidney tissues. AREG is a downstream gene overexpressed by Transforming growth factor-β (TGF-β) during fibrosis, promoting fibroblast to myofibroblast transition (FMT). SRN001 is designed to downregulate generating amphiregulin by RNA interference (RNAi). The goal of this clinical trial is to evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of SRN001 in healthy Korean and Caucasian adult males.
