The Efficacy of Graminex® Flower Pollen Extracts in Healthy Women With Urinary Incontinence
Study Details
Study Description
Brief Summary
The primary objective of this study is to investigate the effect of Graminex® Flower Pollen Extracts in healthy women with urinary incontinence. The change in severity of urinary incontinence between baseline and 24 weeks will be assessed by an International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and compared between the investigational product and placebo groups. Additionally, the safety and tolerability of Graminex® Flower Pollen Extracts, as compared to placebo, will be measured by the occurrence of and/or changes in treatment-emergent adverse events (AEs).
