Brief Summary:

The purpose of this study is to compare the effect of n-acetylcysteine (NAC) plus standard care with matched placebo plus standard of care in patients diagnosed with idiopathic pulmonary fibrosis (IPF) who have the TOLLIP rs3750920 TT genotype. The study will compare the time to a composite endpoint of relative decline in lung function [10% relative decline in forced vital capacity (FVC), first respiratory hospitalization, lung transplantation, or all-cause mortality]

The secondary objectives will be to examine the effect of NAC on the components of the primary composite endpoint, the rates of clinical events, change in physiology, change in health status, and change in respiratory symptoms.


Condition or disease Intervention/treatment Phase
Idiopathic Pulmonary Fibrosis Drug: N-acetyl cysteine Drug: Placebo Phase 3

Detailed Description:

This is a multi-center, randomized, double-blind, placebo-controlled trial of NAC or placebo in about 200 participants with IPF with a TOLLIP rs3750920 TT genotype.

Eligible participants will be randomized in a 1:1 fashion to NAC or placebo, stratified by stable concomitant IPF therapy use (i.e., pirfenidone or nintedanib administered for at least 6 weeks prior to screening) versus no pirfenidone or nintedanib use. Participants will receive 600 mg NAC orally or matched placebo to take three times daily for 24 months.

Primary Outcome Measures :
  1. Time to one of the following composite endpoint criteria: 10% relative decline in forced vital capacity (FVC), first respiratory hospitalization, lung transplant or death from any cause. [ Time Frame: 24 months ]
    This is a composite endpoint of time to 10% relative decline in forced vital capacity (FVC), first respiratory hospitalization, lung transplant or death from any cause. Respiratory hospitalizations will be determined by a blinded clinical events classification (adjudication) committee.

  1. Time to one of the following composite criteria: 10% relative decline in FVC % predicted, first respiratory hospitalization, lung transplant or death from any cause. [ Time Frame: 24 months ]
    This is a composite endpoint of time to 10% relative decline in FVC % predicted, based on the global lung initiative (GLI) reference equation, first respiratory hospitalization, lung transplant or death from any cause. Respiratory hospitalizations will be determined by a blinded clinical events classification (adjudication) committee.
