A Phase IIb, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy, Safety, and Tolerability of Sildenafil Added to Pirfenidone in Patients With Advanced Idiopathic Pulmonary Fibrosis and Intermediate or High Probability of Group 3 Pulmonary Hypertension

ClinicalTrials.gov · COMPLETED, 2020

177 participants

Abstract

This Phase IIb, randomized, placebo-controlled, multicenter, international study will evaluate the efficacy, safety, and tolerability of sildenafil or placebo added to pirfenidone (Esbriet) treatment in participants with advanced IPF and intermediate or high probability of Group 3 pulmonary hypertension (PH) who are on a stable dose of pirfenidone with demonstrated tolerability. Participants will be randomized to receive 1 year of treatment with either oral sildenafil or matching placebo while continuing to take pirfenidone.

Conditions: Idiopathic Pulmonary Fibrosis.

Primary outcome: Percentage of Participants With Disease Progression, as Determined by Relevant Decline in 6 Minute Walk Distance (6MWD) of At Least (>=) 15 Percent (%) From Baseline, Respiratory-Related Non-Elective Hospitalization, or Death From Any Cause.

Enrollment: 177 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 177 participants or records.
