June 19, 2014 updated by: Allergan
This study is an observational trial which will measure the efficacy of onabotulinumtoxinA in treating Cervical Dystonia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

  • Child
  • Adult
  • Older Adult

Description

Inclusion Criteria:

  • Diagnosed with Cervical Dystonia
  • Candidate for botulinum toxin type A therapy
  • New to physician's practice, and/or new to botulinum toxin type A therapy, or has not been injected with botulinum toxin type A for at least 16 weeks as a participant in another clinical trial investigating botulinum toxin type A for cervical dystonia

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
Measure Description
Time Frame
Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) Total Score
Time Frame: 4-6 weeks after treatment 3 (Up to 104.3 weeks)
TWSTRS is an assessment scale used to measure the impact of cervical dystonia on patients. The score is comprised of 3 subscales: Severity, Disability, and Pain, each of which is scored independently. The total of these 3 subscales comprises the TWSTRS total score which is scored from 0 (least symptoms) to 85 (worst symptoms). Higher scores indicate a greater degree of symptom severity.
4-6 weeks after treatment 3 (Up to 104.3 weeks)

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
Time Frame
Percentage of Participants With Cervical Dystonia (CD) Severity Mild
Time Frame: Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)
The physician assessed the patient's severity of CD using a 3-point scale: mild, moderate or severe. The percentage of participants with CD Severity Mild is reported.
Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)
Percentage of Participants With Improvement in Clinicians Global Impression of Change
Time Frame: Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)
The physician evaluated the change in the patient's present condition compared to Baseline using a 7-point scale where: 1= very much improved to 7= very much worse. The percentage of participants where the physician's response was: 1=very much improved, 2=much improved or 3=minimally improved is reported.
Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)
Percentage of Participants With Improvement in the Patient Global Impression of Change
Time Frame: Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)
The patient evaluated the change in their present condition compared to Baseline using a 7-point scale where: 1= very much improved to 7= very much worse. The percentage of participants with responses: 1=very much improved, 2=much improved or 3=minimally improved is reported.
Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)
Pain Numeric Rating Scale Score
Time Frame: Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)
Patients rated their level of pain during the past 24 hours using an 11-point scale where: 0=no pain to 10= pain as bad as you can imagine. A lower number score indicated a lower amount of pain.
Baseline, 4-6 weeks after treatment 3 (Up to 104.3 weeks)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
