Deupirfenidone compared with pirfenidone and placebo in idiopathic pulmonary fibrosis (ELEVATE-IPF): a phase 2b randomized placebo-controlled trial.
Trial report in American journal of respiratory and critical care medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
A Randomized Double-blind, Four-Arm Active and Placebo-controlled Dose-Finding Trial to Evaluate the Efficacy, Tolerability, Safety and Dose Response of LYT-100 in Patients With Idiopathic Pulmonary Fibrosis (IPF)

Abstract
rationaleDeupirfenidone is a strategically deuterated form of pirfenidone that retains pharmacodynamic activity but has a differentiated pharmacokinetic profile that may enable improved efficacy and favorable tolerability in patients with idiopathic pulmonary fibrosis (IPF).
objectivesTo evaluate the efficacy and safety of deupirfenidone compared with placebo and pirfenidone in patients with IPF.
methodsPatients were randomized 1:1:1:1 to deupirfenidone 550 mg TID, deupirfenidone 825 mg TID, pirfenidone 801 mg TID, or placebo. The primary endpoint was the rate of change in forced vital capacity (FVC) for the combined arms of deupirfenidone versus placebo at 26 weeks. The primary and secondary analyses used Bayesian and frequentist approaches, respectively. MEASUREMENTS AND MAIN
resultsA total of 257 patients with IPF were randomized, and the proportion on treatment at the end of the study was 80.0%, 68.3%, 64.6%, and 78.1% for the placebo, pirfenidone, deupirfenidone 550 mg, and deupirfenidone 825 mg arms, respectively. Posterior mean change in FVC for placebo was -110.71 mL (95% credible interval (CI), -148.75, -70.98), and for the combined deupirfenidone arms was -48.42 mL (95% CI, -87.66, -9.04) with a posterior mean difference of 62.29 mL (95% CI l, -6.13, 115.73; posterior probability, 0.985). Using a frequentist approach, the adjusted mean change in FVC for the placebo arm was -112.5 mL (95% CI, -167.2, -57.8), and for the deupirfenidone 825 mg arm was -21.5 mL (95% CI, -78.2, 35.1); the adjusted mean difference was 91.0 mL (95% CI, 12.2, 169.7; P = .02). The most common adverse events for each active treatment arm were gastrointestinal.
conclusionsIn patients with IPF, treatment with deupirfenidone slowed lung disease progression over 26 weeks.
