E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To evaluate the effect of solifenacin versus placebo on bladder wall thickness (BWT) after 12 weeks of treatment. 2. To evaluate the effect of solifenacin versus placebo on urinary Nerve Growth Factor (uNGF) normalized by urine creatinine level (uNGF/Cr) after 12 weeks of treatment in subjects with uNGF above laboratory quantification limit at baseline. |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate the effect on bladder wall thickness (BWT) of a. Solifenacin versus placebo after six (6) weeks of treatment. b. 5mg and 10mg of solifenacin (dose response). 2. To evaluate the relationship of bladder wall thickness (BWT) and a. OAB symptoms at baseline and changes observed during the study. b. Changes observed in subject perceived satisfaction scales. 3. To evaluate the effect on urinary nerve growth factor (uNGF) / creatinine (Cr) of a. Solifenacin versus placebo after six (6) weeks of treatment. b. 5mg and 10mg of solifenacin (dose response). 4. To evaluate the relationship of urinary nerve growth factor (uNGF) / creatinine (Cr) and a. OAB symptoms at baseline and changes observed during the study. b. Changes observed in subject perceived satisfaction scales. 5. To evaluate the relationship between bladder wall thickness (BWT) and urinary nerve growth factor (uNGF) / creatinine (Cr). 6. To evaluate the safety and tolerability of 5mg and 10mg solifenacin. |

E.3 | Principal inclusion criteria |
Subject is eligible for the study if all of the following apply: 1. The subject should be female aged greater than or equal to 18 years of age. 2. The subject should have symptoms of overactive bladder (OAB), including urinary frequency, urgency or urge incontinence, for greater than or equal to 3 months. 3. The subject should have an urodynamic diagnosis of detrusor overactivity (DO). 4. The subject should be either naïve to anti-muscarinic treatment (i.e. no prior history of use of antimuscarinic agents) or 6-months anti-muscarinic treatment free i.e. have had no anti-muscarinic treatment within 6 months) prior to the screening visit. 5. The subject should have a bladder post-void residual volume of less than 30ml. 6. The subject has provided Independent Ethics Committee (IEC)-approved written informed consent and privacy language as per national regulations (e.g., HIPAA Authorization for U.S. sites) prior to any study-related procedures. 7. The subject is available to complete the study. |
|
E.4 | Principal exclusion criteria |
Subject will be excluded from participation if any of the following apply: 1. The subject has a history of stress urinary incontinence, uretheral sphincter incompetence or neurogenic detrusor overactivity. 2. The subject has a history, signs or symptoms suggestive of urinary tract infection (confirmed by positive urine analysis), obstruction or urogenital pro-lapse (greater than grade II). 3. The subject has a history of urinary tract operation within 6 months prior to screening. 4. The subject has an indwelling catheter or permanent catheter fitted. 5. The subject has a history of pelvic area radiotherapy treatment. 6. The subject has uncontrolled diabetes mellitus. 7. The subject has a history of fibromyalgia. 8. The subject is post-partum or breast-feeding within 3 months prior to screening visit. 9. The subject is either pregnant or intends to become pregnant during the study or sexually active, of childbearing potential and is unwilling to utilize a reliable method of birth control such as implants, injectables, combined oral contraceptives, some IUDs, sexual abstinence or vasectomized partner. 10. The subject has a positive pre–study hepatitis B surface antigen, hepatitis C antibody or HIV result at time of screening. 11. The subject has a history of drug and / or alcohol abuse at time of screening. 12. The subject has a history of known or suspected hypersensitivity to solifenacin succinate, oxybutynin hydrochloride, other anti-cholinergics or lactose, to any component of the dosage form or any other allergy, which, in the opinion of the Investigator, contraindicates their participation. 13. The subject has a history of urinary retention, severe gastrointestinal obstruction (including paralytic ileus or intestinal atony or toxic megacolon or severe ulcerative colitis), myasthenia gravis, uncontrolled narrow angle glaucoma or shallow anterior chamber or deemed to be at risk for these conditions. 14. The subject is undergoing hemodialysis or has severe renal impairment (creatinine clearance < 30 ml/min) or moderate hepatic impairment. Subjects who are on treatment with a potent CYP3A4 inhibitor, e.g. Ketoconazole will also be excluded. (Prior to randomization at least one actual serum creatinine value should be available to calculate creatinine clearance according to MDRD / Cockroft Gault). 15. The subject has started or had any dose(s) changes of medication, described in the list in appendix 1B (list of medications permitted with restrictions), within 1 month prior to screening, which will interfere with the study procedures or compromise safety. 16. The subject is currently dosing with medication(s) intended to treat overactive bladder symptoms or has a history of non-drug treatment, such as electrical therapy, magnetic field stimulation, pelvic floor treatment or bladder training intended to treat overactive bladder symptoms within 6 months prior to screening, as described in the list in appendix 1A (list of prohibited medications). 17. The subject is currently receiving or has a history of treatment with alpha blockers, botulinum toxin (cosmetic use is acceptable), resiniferatoxin or pelvic floor muscle relaxants within 9 months prior to screening, as described in the list in appendix 1A (list of prohibited medications) 18. The subject has any clinically significant abnormality following Investigator review of the physical examination which, in the opinion of the Investigator, contraindicates her participation. 19. The subject has any clinically significant abnormal heart rate or blood pressure measurements, at the screening visit, which, in the opinion of the Investigator, prevent safe participation in the study. 20. The subject, in the opinion of the investigator, may find it difficult to adhere to the provisions of treatment and observation specified in the protocol such as the subject diary. 21. The subject has participated in any clinical study less than or equal to 3 months prior to screening. 22. The subject has any clinical condition, diagnosis, symptomatology or ongoing investigation, which, in the opinion of the Investigator, contraindicates their participation. 23. The subject is an employee of Astellas Pharma or any other third party related to the study site. |
