Deupirfenidone (LYT-100) in post-acute sequelae of SARS-CoV-2 with respiratory complications.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The pathophysiology of respiratory complications in post-acute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (PASC) is poorly understood, but a high incidence of progressive pulmonary fibrosis was anticipated. Deupirfenidone (LYT-100) is a selectively deuterated form of pirfenidone that retains antifibrotic and anti-inflammatory activity but with improved tolerability. This study evaluated the safety and efficacy of deupirfenidone in PASC patients with respiratory complications. Methods: Global, double-blind, randomised placebo-controlled trial evaluating 750 mg deupirfenidone twice daily Results: 185 patients were randomised and treated (95 with deupirfenidone, 90 with placebo), with 177 included in the modified intention-to-treat population. The mean age was 54.5 years, 62.7% were male and 10.7% had prior mechanical ventilation. The 6-min walk distance improved across both arms between baseline and day 91 (deupirfenidone 44.3 m (95% CI 24.8-63.8 m) Discussion: Most patients with PASC and respiratory complications showed significant improvement over 91 days irrespective of treatment assignment. Deupirfenidone was well tolerated, with low rates of TEAEs, which supports further investigation in patients with idiopathic pulmonary fibrosis.
