Is this trial a fit for you?

Likely a good fit

Ideal candidates are adult women with MS and AUASS > 8 who have no UTI and meet all inclusion criteria.

Probably not a fit

Patients with recent MS relapse, significant kidney or liver impairment, orthostatic hypotension, or other exclusion criteria may not benefit or may be at higher risk.

What this trial studies

This phase 4 trial enrolls adult women with MS and moderate to severe LUTS to receive either silodosin 8 mg daily or a placebo for 8 weeks. Researchers will use questionnaires and uroflowmetry tests to assess changes in urinary symptoms and voiding parameters. The study compares the active drug to placebo to determine if silodosin can improve LUTS in this population while monitoring safety and tolerability. Participants will have an initial clinic visit before starting treatment and a follow-up visit after 8 weeks for assessments.

Why it matters

Potential benefit: If successful, participants may experience a reduction in urinary symptoms and improved bladder function.

How similar studies have gone: Previous alpha-blocker studies in LUTS have shown potential benefits in similar populations, but this trial addresses a specific MS-related LUTS group with silodosin.
