Description

Pirfenidone is an orally active small molecule drug that may inhibit collagen synthesis, down regulate production of multiple cytokines and block fibroblast proliferation and stimulation in response to cytokines. Pirfenidone has demonstrated activity in multiple fibrotic conditions, including those of the lung, kidney and liver. It is being investigated by InterMune.

Pharmacology

Indication

For the treatment of idiopathic pulmonary fibrosis (IPF).

Associated Conditions
Pharmacodynamics

Pirfenidone is a novel agent with anti-inflammatory, antioxidant, and antifibrotic properties. It may improve lung function and reduce the number of acute exacerbations in patients with idiopathic pulmonary fibrosis (IPF).

Mechanism of action

Pirfenidone is an orally active, small molecule that shows a wide range of biologic activity. In vitro evidence has shown that pirfenidone inhibits collagen synthesis, down-regulates profibrotic cytokines and decreases fibroblast proliferation. Pirfenidone leads to a reduction of TGF-beta2 mRNA levels and of the mature TGF-beta2 protein due to decreased expression and direct inhibition of the TGF-beta pro-protein convertase furin. In addition, pirfenidone reduces the protein levels of the matrix metalloproteinase (MMP)-11, a TGF-beta target gene and furin substrate involved in carcinogenesis.
