| Scientific title |
|
| Acronym | WTPCGTO |

| Countries of trial | United Kingdom |
| Participants - inclusion criteria | At study entry: 1. Female patient aged ≥18 2. Written informed consent obtained 3. Patient is willing and able to complete the frequency volume chart (FVC) and questionnaires correctly 4. Symptoms of overactive bladder (frequency/urge/urge incontinence) for ≥3 months AND/OR previously demonstrated detrusor overactivity (DO) at urodynamics
At randomisation: 1. At least three episodes of urgency or urge incontinence on FVC over 3 days 2. At least frequency ≥8 on FVC over 3 days |
| Participants - exclusion criteria | At study entry: 1. History of allergy to oxybutynin or any of the ingredients of Kentera 2. History of allergy from medical tape or transdermal skin patch 3. Pregnancy, intention to become pregnant during study period, unreliable contraception despite being sexually active, breast feeding 4. Urodynamic proven mixed incontinence 5. Voiding difficulties (flow rate <15 ml/s, or post void residual >50 ml) 6. Patient with indwelling catheter or practicing clean intermittent self-catheterisation (CISC) 7. Evidence of current urinary tract infection (UTI) or bladder stone or malignancy 8. Uncontrolled narrow angle glaucoma, myasthenia gravis, gastric or urinary retention, renal impairment or dialysis, moderate or severe hepatic impairment, chronic intestinal disease (including ulcerative colitis and gastrointestinal obstruction), megacolon, diabetic neuropathy, oesophageal inflammation (hiatus hernia, gastrooesophageal reflux), Parkinson’s disease, or other significant clinical condition (at the discretion of the investigator) 9. Other specific medications: anticholinergics, antispasmodics, anti-parkinsonian, tricyclics, tetracyclics, duloxetine, antihistamines, antiemetics, diuretics, neuroleptics, type I antiarrythmics, opioids, alpha-antagonists, CYP3A4 inhibitors or inducers, any other bladder medication
