Exclusion criteria:
Subjects will be excluded from participation if any of the
following apply:

At screening (visit 1):
1. Subject in the opinion of the investigator has clinically
significant Bladder Outlet Obstruction (BOO).
2. Subject has significant PVR volume (PVR > 150 ml).
3. Subject has significant stress incontinence or mixed
stress/urgency incontinence where stress is the predominant
factor as determined by the investigator
4. Subject has an indwelling catheter or practices intermittent
self-catheterization.
5. Subject has evidence of a Urinary Tract Infection (UTI). If a
urine dipstick shows positive for nitrite, this must be followed
up with a urine sediment and then culture (if the sediment is
positive). The subject should be treated with an appropriate
course of antibiotics. The subject can be enrolled into the study
after successful treatment of the UTI, which is confirmed by a
dipstick test negative for nitrites. If more than 28 days has
passed since the initial screening visit, the subject must repeat
the screening assessments.
6. Subject has chronic inflammation such as interstitial cystitis,
bladder stones, previous pelvic radiation therapy, or previous
or current malignant disease of the pelvic organs (i.e., within
the confines of the pelvis including the bladder and rectum in
both sexes, the prostate in males and the uterus, ovaries, and
fallopian tubes in females; organs of the lower gastrointestinal
tract are not necessarily considered pelvic organs as the distal
ascending colon, the full transverse colon and proximal portion
of the descending colon are in the abdomen).
7. Subject has received intravesical treatment in the past 12
months with e.g., botulinum toxin, resiniferatoxin, capsaicin.
8. Subject has uncontrolled narrow angle glaucoma, urinary or
gastric retention, severe ulcerative colitis, toxic megacolon,
myasthenia gravis or any other medical condition which in the
opinion of the investigator makes the use of anticholinergics
contraindicated.
9. Subject receives non-drug treatment including sacral nerve
stimulation therapy (a bladder training program or pelvic floor
exercises which started more than 30 days prior to entry into
the study can be continued).
10. Subject has moderate to severe hepatic impairment defined as
Child-Pugh Class B or C.
11. Subject has severe renal impairment or End Stage Renal
disease defined as eGFR < 30 ml/min/1.73 m2.
12. Subject has serum creatinine > 150 µmol/L, AST and/or ALT
> 2x upper limit of normal (ULN), ?-GT > 3x ULN, or total
bilirubin 2x ULN, as assessed in screening samples.
13. Subject has severe uncontrolled hypertension, which is defined
as a sitting average systolic blood pressure = 180 mmHg
and/or average diastolic blood pressure = 110 mmHg.
14. Subject has a QTcF interval > 450 ms for males or > 470 ms
for females or is at risk of QT prolongation (e.g., family
history of long QT syndrome, hypokalaemia).
15. Subject has a clinically significant abnormal ECG.
16. Subject has a known or suspected hypersensitivity to
solifenacin, mirabegron or any of the inactive ingredients. This
includes subjects with rare hereditary problems of galactose
intolerance, the Lapp lactase deficiency or glucose-galactose
malabsorbtion.
17. Subject has any other clinically significant condition, which in
the opinion of the investigator makes the subject unsuitable for
the study.
18. Subject has been treated with an experimental device wit
