Summary
Brief summary
The aim of the study is to determine how well the drug BAY1817080 works in OAB patients with
urgency urinary incontinence (UUI), defined as involuntary leakage of urine, accompanied or
immediately preceded by a sudden compelling desire to void.

BAY1817080 is a new drug under development which blocks proteins expressed on the sensory
nerves in the bladder. These nerves seem to overreact in OAB patients.

This study will test if the treatment with BAY1817080 will reduce the frequency of OAB
symptoms. The frequency of OAB symptoms before the treatment and the frequency after 4, 8 and
12 weeks of treatment will be compared.

Another important objective of this study will be the assessment of BAY1817080 safety and
tolerability in this patient population.

BAY1817080 will be compared to a "placebo". A placebo tablet looks like the study drug but
does not have any medicine in it. Using a placebo helps to learn if the study drug works.
Each participant is expected to take part in the study for about 5 months (around 20-22
weeks).
