able to measure his/her vital signs at home at stipulated time points, using the device provided by the study
personnel, and to adequately record the readings

7. Subject is willing and able to complete the micturition diary correctly and is willing and able to measure
his/her vital signs at home at stipulated time points, using the device provided by the study personnel, and to
adequately record the readings
Inclusion Criteria at Visit 3/Baseline
8. Subject continues to meet all inclusion criteria and none of the exclusion criteria for Visit 1;
9. Subject has experienced frequency of micturition on average = 8 times per 24-hour period during the 3-day
micturition diary period (incontinence episode should not be counted as a micturition);
10. Subject must experience at least 1 episode of urgency (grade 3 or 4) per 24-hour period (with or without

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

2. Female subjects of childbearing potential and not using a highly effective method of birth control during the
study and for 30 days after final study drug administration.
3. Male subjects (unless surgically sterile) with female spouses/partners who are of childbearing potential, and not

addition, female spouses/partners of male subjects and who are of childbearing potential should also use a highly
effective method of birth control during the study and for 30 days after final study drug administration. Highly
effective methods of birth control are defined as those, alone or in combination, that result in a low failure rate
(i.e. less than 1% per year) when used consistently and correctly.
4. In the opinion of the Investigator, the subject has clinically significant bladder outflow obstruction at risk of
urinary retention;

9. Subject has diabetic neuropathy;
10. Subject has chronic inflammation such as interstitial cystitis, bladder stones, previous pelvic radiation therapy
or previous or current malignant disease of the pelvic organs;

capsaicin;
13. Subject has uncontrolled narrow angle glaucoma, urinary or gastric retention, severe ulcerative colitis
or Crohn’s Disease, toxic megacolon, myasthenia gravis or any other condition which makes the use of
anticholinergics contraindicated;

Screening, such as myocardial infarction, uncontrolled angina, significant ventricular arrhythmias, heart failure
and stroke;
15. Subject is receiving current non-drug treatment including electro-stimulation therapy (with the exception of a
bladder training program or pelvic floor exercises which started more than 30 days prior to Screening);
16. Subject is using medications intended to treat OAB or prohibited medications. Subject is excluded if using
restricted medications under conditions different to those specified in the Concomitant Medication” section;
17. Subject has known or suspected hypersensitivity to solifenacin succinate, mirabegron or any of their
excipients;
18. Subject has any significant neurological disease or defect affecting bladder function (e.g., neurogenic bladder,
systemic or central neurological disease such as multiple sclerosis [MS] and Parkinson’s disease);
19. Subject has severe hypertension which is defined as a sitting average systolic blood pressure = 180 mmHg
