Inclusion criteria

  1. Male or female of aged over 19 years
  2. Subjects diagnosed with primary cervical dystonia

Exclusion criteria

Exclusion Criteria:

  1. Subjects who have administered botulinum toxin within 16 weeks at the time of baseline
  2. Pregnant or nursing
  3. Females or males who do not agree on proper measure
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. rate of adverse event

    To assess severity and frequency of reported adverse events and clinically-relevant changes in laboratory testing after investigational product injection.

    Time frame: 12 weeks (during the clinical trial)

  2. Change From Baseline in the Total Score of the TWSTRS score.

    The average of the change from baseline in TWSTRS-total score at Weeks 4, 8 and 12 will be determined. full name of TWSTRS is Toronto Western Spasmodic Torticollis Rating Scale. The validated assessment scale TWSTRS is consists of 3 sub-scales. 1. severity (0\~35 points) 2. pain (0\~20 points) 3. disability( 0\~30 points) Total score ranges from 0 to 85 points.

    Time frame: Baseline to Week 4 , Week 8, Week 12

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 22, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
