PASADENA, CA, USA I February 2, 2023 I Arrowhead Pharmaceuticals Inc. (NASDAQ: ARWR) announced today that it has dosed the first subjects in a Phase 1/2a clinical trial of ARO-MMP7, the company’s investigational RNA interference (RNAi) therapeutic designed to reduce the expression of matrix metalloproteinase 7 (MMP7) as a potential treatment for idiopathic pulmonary fibrosis (IPF).

“MMP7 is thought to play multiple roles in IPF pathogenesis, including promoting inflammation and aberrant epithelial repair and fibrosis,” said James Hamilton, M.D., MBA, chief of discovery and translational medicine at Arrowhead. “ARO-MMP7 offers a novel approach to potentially address the significant unmet medical need that exists for patients with IPF, who experience progressive decline of lung function, despite currently available therapies.”

AROMMP7-1001 (NCT05537025) is a Phase 1/2a single ascending dose and multiple ascending dose study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ARO-MMP7 in up to 56 healthy volunteers and up to 21 patients with IPF.

About Arrowhead Pharmaceuticals

Arrowhead Pharmaceuticals develops medicines that treat intractable diseases by silencing the genes that cause them. Using a broad portfolio of RNA chemistries and efficient modes of delivery, Arrowhead therapies trigger the RNA interference mechanism to induce rapid, deep, and durable knockdown of target genes. RNA interference, or RNAi, is a mechanism present in living cells that inhibits the expression of a specific gene, thereby affecting the production of a specific protein. Arrowhead’s RNAi-based therapeutics leverage this natural pathway of gene silencing.
