Trial Outcomes & Findings for A Study Based on Medical Records in Spain That Looks at Diarrhoea Control in People With Pulmonary Fibrosis Who Are Taking Nintedanib (NCT NCT06200714)

This was an observational, post authorization safety study based on newly collected data in patients in Spain with idiopathic pulmonary fibrosis (IPF) and other progressive pulmonary fibrosis (PPF) who were treated with 150 milligrams (mg) of nintedanib twice daily and had suffered a first episode of nintedanib-associated diarrhoea. The study baseline was the first pulmonologist visit due to a first episode of diarrhoea after the initiation of nintedanib treatment.

All participants were screened for eligibility prior to participation in the trial. Participants attended a specialist site which ensured that they (the participants) strictly met all inclusion and none of the exclusion criteria. During the recruitment period, 20 participants were initially screened, with 18 considered for enrollment. One participant was excluded from the analysis set due to not fulfilling all inclusion criteria.

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

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.

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.

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.

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.

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.

The proportion of participants, presented as percentage, who used carob flour for the treatment of nintedanib-associated diarrhoea at any time from diarrhoea initiation to Week 12 follow-up is reported.

The number of participants per treatment category for nintedanib-associated diarrhea is reported. Treatment categories of nintedanib-associated diarrhoea include pharmacological treatments (e.g., loperamide, oral rehydration salt formulations, tannate), non-pharmacological treatments (e.g., carob flour, zinc, probiotics, other dietary interventions, hydration), and a combination of both pharmacological and non-pharmacological treatments.

The number of participants per treatment category for nintedanib-associated diarrhea is reported. Treatment categories of nintedanib-associated diarrhoea include pharmacological treatments (e.g., loperamide, oral rehydration salt formulations, tannate), non-pharmacological treatments (e.g., carob flour, zinc, probiotics, other dietary interventions, hydration), and a combination of both pharmacological and non-pharmacological treatments.

The occurrence of at least one nintedanib dose reduction is reported as the number of study participants, among those who changed their nintedanib dose, who had at least one dose reduction of nintedanib over the course of the study. Dose reduction is defined as a reduction from 150 milligrams, twice daily to 100 milligrams, twice daily.

The occurrence of permanent withdrawal of nintedanib is reported as the number of participants who permanently withdrew nintedanib treatment between diarrhoea initiation and 12-week follow-up. Permanent withdrawal is defined as discontinuing nintedanib treatment (either 150 milligrams or 100 milligrams, twice daily) and not reintroducing it before the 12-week follow-up.

The occurrence of at least one nintedanib dose escalation is reported as the number of participants who had at least one nintedanib dose escalation from diarrhoea initiation to 12-week follow-up. Dose escalation is defined as an increase of nintedanib dose from 100 milligrams to 150 milligrams, twice daily.
