Nerandomilast to slow lung changes in people with a family history of pulmonary fibrosis

Official title: A Double Blind, Randomized, Placebo-controlled Exploratory Trial to Investigate the Efficacy and Safety of Nerandomilast Over 24 Months When Administered in Individuals With Interstitial Lung Abnormalities and a Family History of Pulmonary Fibrosis to Reduce the Risk of Worsening (DROP-FPF)

Run by Boehringer Ingelheim · NCT07201922 · Data updated 2026-11-12

This trial tests whether taking nerandomilast can slow early lung scarring in people aged 40 and older who have a first-degree relative with pulmonary fibrosis and CT evidence of interstitial lung abnormalities.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 40 years or older with at least one first-degree relative with confirmed pulmonary fibrosis, HRCT showing at least 5% interstitial lung abnormalities or ILD, and preserved lung function (FVC ≥80%, DLCO ≥70%).

Probably not a fit

People with already diagnosed or advanced pulmonary fibrosis, worse lung function than the entry criteria, or without a family history of pulmonary fibrosis are unlikely to benefit from this preventive approach.

What this trial studies

This Phase 3, randomized, placebo-controlled trial enrolls adults 40 and older who have at least one first-degree relative with confirmed pulmonary fibrosis and HRCT evidence of interstitial lung abnormalities or ILD. Eligible participants with preserved lung function (FVC ≥80% and DLCO ≥70%) are randomly assigned to receive oral nerandomilast or matching placebo and are followed over time with imaging and lung function tests. The primary aim is to see if nerandomilast slows the development or extent of lung scarring compared with placebo. The trial is conducted at academic and community research centers in California, Colorado, and Florida.

Why it matters

Potential benefit: If successful, nerandomilast could slow progression of early lung abnormalities and reduce or delay the onset of symptomatic pulmonary fibrosis.

How similar studies have gone: Antifibrotic drugs have slowed progression in established pulmonary fibrosis, but using a preventative drug in relatives with early CT changes is relatively novel and not yet proven.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Individuals ≥40 years of age at the time of first signed informed consent at Visit 1a
* Participants must have at least 1 first-degree relative (biological parent, sibling, or child) with confirmed pulmonary fibrosis (idiopathic pulmonary fibrosis \[IPF\], idiopathic nonspecific interstitial pneumonia \[NSIP\], and/or pulmonary fibrosis due to known genetic cause \[e.g. short telomere syndrome, mucin 5B (MUC5B) mutation, surfactant protein mutations\])
* High resolution computed tomography (HRCT) scan with evidence of interstitial lung abnormalities involving at least 5% of a single lung zone or interstitial lung disease (ILD), based on central evaluation
* Forced vital capacity (FVC) ≥80% of predicted normal at Visit 1b
* Diffusing capacity of the lungs for carbon monoxide (DLCO) corrected for hemoglobin ≥70% of predicted normal at Visit 1b Further inclusion criteria apply.

Exclusion Criteria:

* Prior known pulmonary fibrosis that, in the opinion of the Investigator, requires treatment with approved therapies
* Prebronchodilator forced expiratory volume in 1 second (FEV1)/FVC \<0.7 at Visit 1b
* HRCT findings consistent with probable or definite usual interstitial pneumonia (UIP) pattern
* Any medical condition that is known to predispose to the development of pulmonary fibrosis (e.g. known connective tissue disease)
* Prior or current use of nerandomilast, nintedanib, or pirfenidone Further exclusion criteria apply.
