Safety profile of desmopressin tablet for enuresis in a prospective study.

INTRODUCTION

This pre-specified sub-study of the desmopressin response in primary nocturnal enuresis study (DRIP study) evaluates the safety profile of the oral desmopressin tablet in children with primary nocturnal enuresis. Endpoints are adverse events and change in body mass index.

METHODS

The DRIP study was an open-label, intention-to-treat, phase IV, multi-national study. Overall, 936 patients were screened and 744 children aged 5-15 years with previously untreated primary nocturnal enuresis were eligible to receive the study medication desmopressin once daily as an oral tablet formulation. At each visit, adverse events were questioned and observed signs or symptoms were recorded.

RESULTS

Overall, 222 (30%) patients experienced 404 treatment-emergent adverse events. The proportion of patients experiencing treatment-emergent adverse events was similar regardless of patient gender or age. Most treatment-emergent adverse events were experienced in three system organ classes: gastrointestinal disorders; infections and infestations; and respiratory, thoracic and mediastinal disorders and were considered unrelated to the study drug. There was a slight increase in body mass index from screening levels during the study, however, clinically not significant.

CONCLUSION

Desmopressin tablet treatment is well tolerated in children with primary nocturnal enuresis, regardless of patient gender or age.
