E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to confirm the safety and efficacy of NT 201 after one injection session in the treatment of patients with cervical dystonia. |
|
E.2.2 | Secondary objectives of the trial |
As secondary objectives the efficacy and safety profile and the duration of treatment effect of NT 201 in long-term treatment with repeated injection sessions will be determined. In addition, the usefulness of a patient diary for achievement of optimal treatment during this period in clinical practice will be investigated. As part of the safety evaluations during the Main Period and the Extension Period, the incidence of adverse events (AEs) and the formation of antibodies will be investigated.

E.3 | Principal inclusion criteria |
- Willingness of the patient to participate as documented by written informed consent - Male or female patient aged ≥ 18 and < 76 years - A clinical diagnosis of cervical dystonia, i.e., spasmodic torticollis, of predominantly rotational form with a need for injection. Cervical dystonia is characterized by involuntary, inappropriate neuromuscular hyperactivity in neck and shoulder muscles leading to abnormal head movements and postures - Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS, see protocol) – total score at baseline ≥ 25 - TWSTRS – severity score ≥ 10 - TWSTRS – disability score ≥ 3 - Patient must be on a stable dose of other medications (if any) used for focal dystonia treatment (e.g., anticholinergics and benzodiazepines) for ≥ 3 months prior to and throughout the Main Period and if possible, throughout the Extension Period - Negative pregnancy test at trial entry for female of childbearing potential (premenopausal female or postmenopausal female with last menses less than 12 months ago) - Woman of childbearing potential using highly effective methods of birth control, defined as those which result in a low failure rate (i.e., less than 1% per year) when used constantly and correctly such as hormonal contraception or intrauterine contraceptive device or combination of two barrier methods (e.g., condom or diaphragm plus spermicidal cream) - For pre-treated patients only: Source documentation of the last two consecutive injection sessions with botulinum neurotoxin type A and stable treatment response directly prior to trial entry. - For pre-treated patients only: At least 10 weeks must have passed between the last injection session with botulinum neurotoxin type A for cervical dystonia and the time of the baseline visit. - For pre-treated patients only: The most recent injection session with botulinum neurotoxin for cervical dystonia must have been at a dose of ≤ 300 units of Botox® or Xeomin® or ≤ 1,200 units Dysport® For the longterm extension period: - Negative pregnancy test for female of childbearing potential (premenopausal female or postmenopausal female with last menses less than 12 months ago) - Woman of childbearing potential using highly effective methods of birth control, defined as those which result in a low failure rate (i.e., less than 1% per year) when used constantly and correctly such as hormonal contraception or intrauterine contraceptive device or combination of two barrier methods (e.g., condom or diaphragm plus spermicidal cream) - At least 10 weeks must have been passed since the last injection session with botulinum neurotoxin type A for cervical dystonia
