Clinical Study of Solifenacin Succinate in Patients With Bladder Symptoms Due to Spinal Cord Injury or Multiple Sclerosis (SONIC)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00629642
Recruitment Status : Completed
First Posted : March 6, 2008
Last Update Posted : September 1, 2017

Astellas Pharma Inc

Brief Summary:
A clinical study to evaluate the efficacy and safety of solifenacin in patients with bladder symptoms due to spinal cord injury or multiple sclerosis

Condition or disease Intervention/treatment Phase
Multiple Sclerosis Neurogenic Bladder Spinal Cord Diseases Drug: Solifenacin Succinate Drug: Oxybutynin Hydrochloride Drug: Placebo Phase 4

Detailed Description:
A clinical study to compare the efficacy and safety of solifenacin succinate in patients with neurogenic detrusor overactivity. In this randomized, double blind, double dummy study solifenacin will be compared to placebo and an active comparator, oxybutynin hydrochloride. Patients will be randomized to one of four treatment arms; solifenacin 10mg, solifenacin 5mg, placebo or oxybutynin 15mg. Patients will be assessed over a four week treatment period.

    • Multiple sclerosis(MS)(EDSS≤8) or
    • Spinal cord injury(SCI)(partial or complete lesions)
  • MS or SCI symptoms should be stable for >= 6 months
  • Neurogenic detrusor overactivity symptoms should be stable for >= 6 months
  • Subject is willing and able to perform clean, intermittent, catheterization, if required
  • Subject is willing and able to take study medication in compliance with the protocol

Exclusion Criteria:

  • Subjects with neurogenic detrusor overactivity due to Parkinson's or cerebrovascular disease
  • Subjects with Sjögren's Syndrome or any similar symptoms
  • Subjects with evidence of a symptomatic urinary tract infection, chronic inflammation such as interstitial cystitis, bladder stones, previous pelvic radiation therapy or previous or current malignant disease of the pelvic organs
  • Subjects with stress incontinence or mixed incontinence where stress is the predominant factor as determined by the investigator
  • Subjects with evidence of pressure sores >= grade 2
  • Subjects with a history of bladder sphincterotomy
  • Subjects with known history of vesico-ureteral reflux without upper urinary tract infection
  • Any clinically significant condition, which in the opinion of the investigator makes the subject unsuitable for the study or includes a history of acute urinary retention, severe gastrointestinal obstruction (including paralytic ileus or intestinal atony), severe gastrointestinal conditions (including toxic megacolon or ulcerative colitis), myasthenia gravis, narrow angle glaucoma or shallow anterior chamber
  • Subjects undergoing hemodialysis
  • Subjects with severe hepatic impairment
  • Concurrent use of drugs intended to treat symptoms of overactive bladder
  • Use of antidepressants or muscle relaxants which have not been administered at a constant dose for >= 3 months
  • Use of non-drug treatment intended to treat overactive bladder symptoms including electrostimulation therapy, botulinum toxin and vanilloids therapy in the six months prior to the commencement of the study
  • Use of permanent, indwelling catheters
  • Known or suspected hypersensitivity to solifenacin succinate, oxybutynin hydrochloride, other anti cholinergics or lactose
  • Concomitant use of a strong CYP3A4 inhibitor, e.g. ketoconazole
  • Pregnant women, women who intend to become pregnant during the study, women of childbearing potential who are sexually active and practicing an unreliable method of birth control or women who will be lactating during the study. Reliable contraceptive methods are intra-uterine devices, contraceptive pills of combination type, hormonal implants and injectable contraceptives
  • Participation in any clinical study within 30 days of randomization, or the limit set by national law, whichever is longer
