November 22, 2022 updated by: Lars Frich, Oslo University Hospital

Prevention of Bladder Dysfunction in Acute Spinal Cord Injury. A Double-blind, Randomized, Placebo-controlled Study to Explore the Effect of Early Treatment With Onabotulinumtoxin A on Development of Detrusor Overactivity

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (ADULT, OLDER_ADULT)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Presence of neurogenic detrusor overactivity during cystometry, defined as contractions with amplitudes above 40 cm H2O.
Time Frame: 12 months
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment.
