Overview

Parisiran is a first in class short interfering RNA for the treatment of patients with polyneuropathy caused by hereditary transthyretin-mediated amyloidosis . It is marketed as Onpattro which is formulated as patisiran within a liposome envelope for better delivery to the liver, where transthyretin is produced. The approval for Onpattro was granted to Alnylam Pharmaceuticals, Inc. in August of 2018. Onpattro has been granted Fast Track, Priority Review and Breakthrough Therapy, and Orphan Drug designations.

Patisiran (Onpattro): A Comprehensive Monograph on a First-in-Class RNAi Therapeutic for Hereditary Transthyretin-Mediated Amyloidosis

Executive Summary

Patisiran, marketed under the brand name Onpattro, represents a paradigm shift in the treatment of genetic disorders and marks the clinical translation of a Nobel Prize-winning scientific discovery into a potent therapeutic agent.[1] As the first-ever small interfering RNA (siRNA) therapeutic approved by major global regulatory bodies, Patisiran has fundamentally altered the treatment landscape for hereditary transthyretin-mediated (hATTR) amyloidosis, a rare, progressive, and fatal disease.[4] This report provides a comprehensive analysis of Patisiran, covering its molecular basis, pharmacological profile, clinical development, and its role in the contemporary therapeutic armamentarium.

The mechanism of action of Patisiran is rooted in RNA interference (RNAi), a natural biological process of post-transcriptional gene silencing. The drug is a double-stranded siRNA specifically designed to target the messenger RNA (mRNA) of the transthyretin (TTR) gene. By mediating the catalytic degradation of both mutant and wild-type TTR mRNA within hepatocytes, Patisiran dramatically reduces the hepatic synthesis of the pathogenic TTR protein, thereby addressing the root cause of hATTR amyloidosis.[7] This targeted knockdown of TTR protein production prevents the formation and deposition of amyloid fibrils in tissues, which is the underlying driver of the disease's devastating multisystem pathology.
