Omegapres versus solifenacin plus mirabegron for children with primary mono‑symptomatic nocturnal enuresis

A Randomized Controlled Trial Comparing Mirabegron and Solifenacin Combination Therapy Versus Desmopressin Monotherapy in Treatment of Children With Primary Mono-Symptomatic Nocturnal Enuresis

Phase 3 Interventional Mansoura University · NCT07199894

This tests whether a daily combination of solifenacin and mirabegron reduces nightly bedwetting more than Omegapres in children with primary mono‑symptomatic nocturnal enuresis.

What this trial studies

Children with primary mono‑symptomatic nocturnal enuresis will receive either a daily combination of solifenacin and mirabegron or Omegapres for three months and will be followed monthly. Caregivers will keep a diary of wet nights and symptoms while clinic visits include checks and safety tests. The trial's main outcomes are change in number of wet nights and the safety/tolerability of the drug combination. Participants with bowel dysfunction, psychiatric illness, or respiratory sleep disorders are excluded.

Who should consider this trial

Good fit: Children aged 5 years or older with primary mono‑symptomatic nocturnal enuresis and no other lower urinary tract symptoms are the intended participants.

Not a fit: Children with bowel dysfunction, psychiatric illness, respiratory sleep disorders, congenital urinary tract anomalies, or non‑mono‑symptomatic enuresis are unlikely to benefit from this regimen.

Why it matters

Potential benefit: If successful, the combination could reduce the number of wet nights and provide an alternative for children who do not respond to desmopressin alone.

How similar studies have performed: Smaller studies and off‑label use of anticholinergics and mirabegron have shown benefit for detrusor overactivity and some enuresis cases, but large phase‑3 data combining these two drugs versus desmopressin are limited.
