NCT07533565

Brief Summary

This study was a prospective, interventional, pilot clinical study conducted over 3 months on cirrhotic patients with overactive bladder and asthma, evaluating the real-world applicability of selected PBPK-guided dosing regimens. Patients were stratified according to Child-Pugh class (CP-A, CP-B, and CP-C) and administered mirabegron and montelukast at doses corresponding to the closest commercially available strengths to Simcyp®-optimized doses. Clinical evaluation included number of incontinence episodes, number of micturation, volume voided per micturation, cough, and wheezing. Routine laboratory investigations were conducted to assess efficacy and safety and included liver function tests (serum albumin, total bilirubin, alanine aminotransferase \[ALT\], and aspartate aminotransferase \[AST\]), kidney function tests (serum creatinine and blood urea nitrogen \[BUN\]), and CBC.

Outcome Measures

Primary Outcomes (1)

  • Change in number of urinary incontinence episodes per 24 hours

    The primary outcome will be the change from baseline in the number of urinary incontinence episodes recorded over 24 hours, assessed before and after treatment in the control and treatment groups. Urinary incontinence episodes will be documented using a 24-hour bladder diary.

    3 months

Secondary Outcomes (1)

  • Monitoring of Adverse Effects
