A Study Based on Medical Records in Spain That Looks at Diarrhoea Control in People With Pulmonary Fibrosis Who Are Taking Nintedanib

April 21, 2026 updated by: Boehringer Ingelheim

Observational, Multicentre, Prospective, Real-world Post-authorization Safety Study Describing the Achievement of Nintedanib-associated DIArrhoea Control After 12 Weeks of Follow-up in Patients With Idiopathic puLmonary FIBrosis (IPF) and Progressive Pulmonary Fibrosis (Other Than IPF) in Spain: the DIALFIB Study

This is an observational, non-interventional, and prospective post authorization safety study (PASS) that will describe the real-world proportion of patients that achieve nintedanib-associated diarrhoea control after 12 weeks of follow-up, in hospital settings in Spain. It will include outpatients (i.e., those attending ambulatory visits) with interstitial lung diseases (IPF) and other progressive pulmonary fibrosis (PPF) treated with nintedanib (150 mg bid) and having a first episode of diarrhoea after nintedanib initiation.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Achievement of Diarrhoea Control at Week 12 Follow-up While Taking the Optimal Nintedanib Dose
Time Frame: 12 weeks after baseline visit.
The percentage of participants who achieved diarrhoea control while taking the optimal nintedanib dose (150 milligrams, twice a day) at 12-week follow-up referent to diarrhoea initiation is described. Achievement of diarrhoea control (yes/no) is defined as the passage of fewer than 3 loose or liquid stools in a 24-hour period. Loose or liquid stools were defined as stools with a Bristol Stool Form Scale (BSFS) score of 6 or 7. The BSFS classifies stool into seven categories based on their consistency. The scale ranges from 1 (hard, separate lumps) to 7 (entirely liquid), with scores 1 and 2 indicating constipation and scores 6 and 7 indicating diarrhoea.
12 weeks after baseline visit.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Absolute Change in the Proportion of Participants Taking the Optimal Nintedanib Dose at Week 12 Follow-up
Time Frame: 12 weeks after baseline visit.
The proportion of participants, presented as percentage, taking the optimal nintedanib dose (150 milligrams, twice a day) at 12-week follow-up referent to diarrhoea initiation is described.
12 weeks after baseline visit.
Absolute Change From Baseline in BSFS Score at Week 12 Follow-up
Time Frame: At baseline and at Week 12.
The absolute change in Bristol Stool Form Scale (BSFS) score at the 12-week follow-up, as compared to the baseline visit, is reported. The BSFS classifies stool into seven categories based on their consistency. The scale ranges from 1 (hard, separate lumps) to 7 (entirely liquid), with scores 1 and 2 indicating constipation and scores 6 and 7 indicating diarrhoea. The baseline value was measured referent to the day of diarrhoea initiation, while the Week 12 timepoint was measured as the mean value from the last 7 days.
At baseline and at Week 12.
Absolute Change From Baseline in Number of Stools Per Day at Week 12 Follow-up
Time Frame: At baseline and at Week 12.
The absolute change from baseline in number of stools per day at 12-week follow-up is reported. The baseline value was measured referent to the day of diarrhoea initiation, while the Week 12 timepoint value was collected as a mean number per patient in the last 7 days.
At baseline and at Week 12.
Absolute Change From Baseline in Current Body Weight at Week 12 Follow-up
Time Frame: At baseline and at Week 12.
The absolute change from baseline in current body weight (kilograms) at Week 12 follow-up is reported. The baseline value was measured referent to the day of diarrhoea initiation, while the Week 12 timepoint was measured as the mean value from the last 7 days.
At baseline and at Week 12.

At baseline visit.
Number of Participants Per Treatment Category for Nintedanib-associated Diarrhoea at Week 12 Follow-up
Time Frame: 12 weeks after baseline visit.
