Real-World Treatment Patterns Among Pediatric and Adult Patients with Crohn's Disease in the United States.

BACKGROUND

The advent of biologics has expanded treatment options for Crohn's disease (CD). This study assessed treatment patterns in pediatric and adult patients with CD in the United States during 1- and 3-year follow-up periods.

METHODS

This retrospective, claims-based cohort study utilized the Merative™ MarketScan Research Databases from January 1, 2014, to December 31, 2021. The index date was the date of the first CD diagnosis during the identification period. Among pediatric and adult CD cohorts, patients were stratified into two subgroups: (a) previously diagnosed (presence of a CD claim) and (b) newly diagnosed (absence of a CD claim) in the 12-month pre-index period. Results were summarized descriptively.

RESULTS

Data from 2809 pediatric and 25,940 adult patients were analyzed at 1-year follow-up. Mean age in years was 13.5 for pediatric and 46.0 for adult patients. Combination therapies were more common in pediatric versus adult patients, especially among those newly diagnosed with CD (38.2% vs 13.9%). A higher percentage of pediatric patients were prescribed biologics than adults (35.1% vs 24.3%). Numerically shorter time from diagnosis to corticosteroid initiation was observed in pediatric versus adult patients (9.5 vs 35 days). Higher persistence to biologics was observed in pediatric versus adult patients (94.6% vs 87.1%).

CONCLUSIONS

Combination therapies with biologics were more frequent among pediatric patients than adults. Although the overall treatment pattern among pediatric and adult patients was similar, early initiation of corticosteroids and adoption of biologics were more frequently observed in pediatric than adult patients, consistent with pediatric CD presenting with more aggressive disease.
