About this study
Official title: A Phase III, Randomised, Double-blind and Open Label Phase, Active and Placebo Controlled Study Comparing the Short-term Efficacy of Two Formulations of Clostridium Botulinum Type A Toxin (Dysport and Dysport NG) to Placebo, and Assessing the Short and Long Term Efficacy and Safety of Dysport NG Following Repeated Treatments of Subjects With Cervical Dystonia
The purpose of this study is to evaluate how well a new drug called Dysport NG works and how safe it is, when it is used for the treatment of cervical dystonia. Dysport NG will be compared to an approved drug called Dysport.
Read the detailed description
The primary study objectives will be assessed in terms of improvement of the subject's CD at a pre-defined time point after treatment. The primary study objectives are to demonstrate the superiority of Dysport NG to placebo in terms of efficacy and to test the non-inferior efficacy of Dysport NG, when compared to Dysport, in CD subjects. In addition to testing for the primary study objectives, the superiority in terms of efficacy of Dysport versus placebo, will be assessed.
This clinical study was designed and implemented and reported in accordance with the International Conference on Harmonization (ICH) Harmonized Tripartite Guidelines for Good Clinical Practice (GCP), with applicable local regulations (including European Directive 2001/20/EC, US Code of Federal Regulations Title 21, and with the ethical principles laid down in the Declaration of Helsinki.
A large body of evidence demonstrates the safety and efficacy of Dysport across several clinical indications. This study was the first use of Dysport NG in humans with CD. The active substance (BTX-A-HAC) in Dysport NG was the same as in the currently marketed Dysport product and had the same mechanism of action. Dysport NG was, therefore, expected to have the same efficacy and safety profile in humans as Dysport, with the advantage of eliminating the potential risk of transmission of infective agents, by the substitution of plant and synthetic products for human and animal-derived products. However, due to the change of excipient, thorough assessment of the safety and efficacy of Dysport NG is necessary. Previous clinical studies indicate that the maximum effect of Dysport and maximum improvements in CD are observed approximately 4 weeks post treatment, after which there is a gradual return to baseline disease status. The Week 4 follow up visit after the first treatment cycle was therefore, chosen as the primary time point of interest. Retreatment is necessary in order to maintain the beneficial effect and the long term treatment of CD. Previously conducted long term studies demonstrate the maintenance of the therapeutic effect of Dysport following repeated treatments, with a favourable short and long term safety and immunogenicity profile.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) Total Score Following First Treatment Cycle
TWSTRS measures the degree of CD and is comprised of three different components, namely Severity, Disability and Pain subscales. There is an ordinal scale score and range for each component. Severity scores range from 0 (absence of severity) to 35 (maximum severity), Disability scores range from 0 (no disability) to 30 (maximum disability) and Pain scores range from 0 (no pain) to 20 (maximum pain). TWSTRS Total score is the sum of the 3 component scores ranging from 0 to a maximum of 85, with higher scores denoting worse outcome. If the change from baseline is negative, this represents an improvement in symptoms.
Measured: Baseline and Week 4

TWSTRS measures the degree of CD and is comprised of three different components, namely Severity, Disability and Pain subscales. There is an ordinal scale score and range for each component. Severity scores range from 0 (absence of severity) to 35 (maximum severity), Disability scores range from 0 (no disability) to 30 (maximum disability) and Pain scores range from 0 (no pain) to 20 (maximum pain). TWSTRS Total score is the sum of the 3 component scores ranging from 0 to a maximum of 85, with higher scores denoting worse outcome.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Botulinum toxin type A in people with Cervical Dystonia, run by Ipsen at 57 sites in 11 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 57 sites in Germany, Ukraine, France, Poland, Russia and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 24 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
