- Intervention Model: FACTORIAL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None

Eligibility Criteria:
Inclusion Criteria:~* Inclusion Criteria at Visit 1/Screening:~  * Subject has a Body Mass Index (BMI) of between 18 and 35 kg/m\^2 and a total body weight between 50 and 95 kg;~ * Subject is willing and able to complete the micturition diary and questionnaires 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;~ * Subject has symptoms of overactive bladder (OAB; urinary frequency, urgency and/or urgency incontinence) for at least 3 months.~* Inclusion Criteria at Visit 3/Baseline:~  * 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);~ * Subject must experience at least 1 episode of urgency (grade 3 or 4) per 24-hour period (with or without urgency incontinence) during the 3 day micturition diary period.~Exclusion Criteria:~* Exclusion Criteria at Visit 1/Screening:~  * Subject is breastfeeding, pregnant or intends to become pregnant during the study. The pregnancy test (Beta Human Chorionic Gonadotropin in serum) at Screening must be negative in women of childbearing potential;~ * 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.~ * Male subjects (unless surgically sterile) with female spouses/partners who are of childbearing potential, and not using a barrier method of contraception during the study and for 30 days after final study drug administration. In 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.~ * Subject has significant post-void residual (PVR) volume (\> 150 mL);~ * Subject has significant stress incontinence or mixed stress/urgency incontinence where stress is the predominant factor as determined by the Investigator (for female subjects confirmed by the cough provocation test);~ * Subject has a neurological cause for detrusor overactivity;~ * Subject has an indwelling catheter or practices intermittent self-catheterization;~ * Subject has diabetic neuropathy;~ * Subject has chronic inflammation such as interstitial cystitis, bladder stones, previous pelvic radiation therapy or previous or current malignant disease of the pelvic organs;~ * Subject has had previous lower urinary tract or pelvic floor surgery (except cystoscopy);~ * Subject has had intravesical treatment in the past 12 months with e.g., botulinum toxin, resiniferatoxin, capsaicin;~ * 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;~ * Subject has clinically significant cardiovascular or cerebrovascular diseases within 6 months prior to Screening, such as myocardial infarction, uncontrolled angina, significant ventricular arrhythmias, heart failure and stroke;~ * 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);~ * Subject is using medications intended to treat OAB or prohibited medications.~ * Subject has known or suspected hypersensitivity to solifenacin succinate, mirabegron or any of their excipients;~ * 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);~ * Subject has severe hypertension which is defined as a sitting average systolic blood pressure ≥ 180 mmHg and/or an average diastolic blood pressure ≥ 110 mmHg;~* Exclusion Criteria at Visit 2/Placebo Run-In:~  * Subject has evidence of a urinary tract infection (UTI) (urine culture containing \> 100,000 cfu/mL). The subject can be enrolled into the study after successful treatment of the UTI (confirmed by a laboratory result of negative urine culture). However, the subject must be re screened if the initial screening visit was \> 28 days;~ * Subject has a QT interval \> 450 ms or is at risk of QT prolongation (e.g., family history of long QT syndrome, hypokalaemia) or is on drug treatment known to be associated with QT prolongation;~ * Subject has clinically significant abnormalities on the 12 lead electrocardiogram (ECG);~ * Subject has serum creatinine \> 150 µmol/L, aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) \> 2x upper limit of normal (ULN), gamma-glutamyltransferase (γ-GT) \> 3x ULN, or total bilirubin \> 2x ULN, as assessed in Screening samples;~* Exclusion Criteria at Visit 3/Baseline:~  * Subject had an average total daily urine volume \> 3000 mL as recorded in the micturition diary period;~ * Subject has severe hypertension which is defined as a sitting average systolic blood pressure ≥ 180 mmHg and/or an average diastolic blood pressure ≥ 110 mmHg.
