入选标准

  • 1.Male or female patients aged 18-65 years, with urodynamic evidence of neurogenic detrusor overactivity (phasic or uninhibited detrusor contraction) arising as a consequence of spinal cord injury or pathology.
  • 2.Evidence of phasic uninhibited detrusor contraction on fast fill cystometry at the beginning of Period 1.
  • 3.Demonstrable provoked uninhibited detrusor contraction following force fill at the beginning of Period 1.
  • 4.Subjects capable of understanding and giving written informed consent after full discussion concerning the nature of the research.
  • 5.Female subjects must have a negative pregnancy test.
  • 6.Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the trial.
  • 7.Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range
  • F.1.3 Elderly (>=65 years) no
  • F.1.3.1 Number of subjects for this age range

排除标准

  • 1.Subjects who do not provide written consent to participate in the study
  • 2.Subjects who have a medical condition that would impair their ability to participate reliably in the study.
  • 3.Subjects who are pregnant or lactating.
  • 4.Subjects with a recent history of autonomic dysreflexia (AD) or AD which is associated with urodynamic investigations
  • 5.Treatment within 7 days (or 5x plasma half-life, if longer) preceding the study, or expected to start treatment during the study with:
  • a.anticholinergic drugs
  • b.drugs with significant anticholinergic effects such as tricyclic antidepressants
  • c.drug treatment for overactive bladder. Estrogen treatment initiated more than 2 months prior to randomization is allowed.
  • 6.Use of inhibitors of the metabolism of tolterodine:
  • a.Potent cytochrome P450 3A4 inhibitors such as macrolide antibiotics (erythromycin and clarithromycin), antifungal agents (ketoconazole and itraconazole), cimetidine, MAOIs, and protease inhibitors. Drugs and/or herbal preparations capable of inducing hepatic enzyme metabolism (e.g., barbiturates, rifampin, carbamazepine, phenytoin, primidone or St. John’s Wort). These must be discontinued within 30 days (or 5 half-lives of inducing/inhibiting agent, whichever is longer) of enrollment in the study.
  • b.Fluoxetine must be discontinued at least 5 weeks before first dose of study medication.
  • c.Have consumed grapefruit or grapefruit-containing products within 7 days prior to the first dose of study medication
  • 7.Subject on a variable dosage of any drug with anticholinergic side effects, or subject expected to start such treatment during the study.
  • 8.Have a known history of hypersensitivity, allergy, severe adverse drug reaction or intolerance to anticholinergic drugs, including tolterodine.
  • 9.Have contraindications to the use of anticholinergic drugs, e.g., uncontrolled narrow-angle glaucoma, urinary retention, significant urinary outflow obstruction (not including sphincter dyssynergia), gastric retention. Significant urinary outflow obstruction is defined as being a urinary pressure/flow study in the obstructed range of the Abrams/Griffiths nomogram or a maximum urinary flow rate <15 mL/sec.
  • 10.Subjects who have evidence of alcohol abuse or abuse of controlled substances.
  • 11.Subject who has received any electrostimulation or bladder retraining within the three months before randomization, or is expected to start such therapy during the study period.
  • 12.Chronic persistent local pathology that may lead to urinary symptoms e.g. urinary tract infection, marked cystocele or pelvic prolapse, interstitial cystitis, bladder stones, unexplained hematuria (> 1+ on dipstick test unless fully investigated prior to randomization to exclude significant urological disease).
  • 13.Have a clinically significant ECG abnormality at screening, except those with non-clinically significant sinus tachycardia or sinus bradycardia. Screening 12-lead ECG demonstrating QTC>430 msec (males) and QTc>450 msec (females).
  • 14.History or evidence of major hematological, renal or hepatic abnormalities (subjects with clinically significant hepatic (Child Pugh C classification) or significant renal impairment serum creatinine 3xULN).
