Clinical Trial Summary

This study is a double blind, randomized, placebo controlled trial to explore the effect of early treatment with Onabotulinumtoxin A in patients with acute complete motor spinal cord injury (SCI) on the development of neurogenic detrusor overactivity (NDO). A total of 20 patients will be randomized to intra-detrusor injection of 300 U Onabotulinumtoxin A in 30 ml NaCl 0.9 % or placebo with 30 ml NaCl 0.9 %. Bladder biopsies will be obtained in the same procedure. The treatment will be repeated after three months. All included patients will be evaluated with urodynamic examinations. Follow-up is 12 months after the first treatment. The primary endpoint of the study is development of NDO.

Outcome

Type Measure Description Time frame Safety issue
Other Detrusor pathophysiology Differences in levels of transmitters and receptors relevant to development of bladder dysfunction, measured in urine samples and bladder biopsies, to gain knowledge of the pathophysiology behind neurogenic detrusor overactivity. 12 months
Primary Presence of neurogenic detrusor overactivity during cystometry, defined as contractions with amplitudes above 40 cm H2O. 12 months
Secondary Urodynamic parameters Maximal detrusor pressure (cmH2O), maximal bladder capacity (ml), compliance (?cmH2O/?ml), and occurrence of DSD. 12 months
Secondary Quality of life (QOL) in the treated group compared to the placebo group 12 months after first treatment. 12 months
Secondary Occurrence of complications. 12 months
