About this study
Official title: A Phase II, Multicentre, Randomised, Double-blind, Parallel-Group, Placebo Controlled Study to Evaluate the Efficacy and Safety of IPN10200 as a Treatment for Cervical Dystonia in Adult Participants
The purpose of this study is to evaluate the efficacy and safety of the study drug, Corabotase (also known as IPN10200), and to assess how well it works when compared with placebo in treating Cervical Dystonia (CD) in adults.
CD can cause a series of abnormalities and symptoms in the head and neck that can lead to neck pain and stiffness, and headaches. CD is believed to involve deep parts within the brain that control movement, but genetic factors, environmental factors, and abnormalities in the brain may also play a role.
Read more
The usual treatment for CD includes injecting BoNT into the affected muscles, but the treatment only lasts about 3 months. Corabotase is designed to last for a longer period.
The study will consist of two periods:
- A Screening Period of up to 4 weeks (28 days) to assess whether a participant can take part in the study and requires at least one visit.
- A Treatment Period of 36 weeks.
On Day 1 of the treatment period, participants will receive either Corabotase Dose A or Dose B (additional participants may receive Corabotase Dose C) of the study drug, or placebo distributed into different muscles in the head, neck and shoulders. Participants may continue some other medications, but details need to be recorded.
There will be 10 visits to the clinic in person and one remote visits (phone call) (12 visits to the clinic for participants who receive Dose C). Participants will undergo blood samplings, urine collections, physical/neurological examinations, and clinical evaluations. Participants will also need to complete questionnaires throughout the study.
The total study duration for a participant will be up to 40 weeks (approximately 9 months).

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Baseline in the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total score
The Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) is a rating scale for Cervical Dystonia (CD) consisting of three subscales: severity, disability and pain scales. The total score is the sum of each of the subscales, with a range of 0 to 85, where higher scores are indicative of greater impairment.
Measured: At Week 4
Secondary outcomes (20)
Change from Baseline in the TWSTRS total score at all other scheduled timepoints post injection until Week 36
The Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) is a rating scale for Cervical Dystonia (CD) consisting of three subscales: severity, disability and pain scales. The total score is the sum of each of the subscales, with a range of 0 to 85, where higher scores are indicative of greater impairment.
Measured: At all timepoints post injection until Week 36.
Change from Baseline in the TWSTRS-Pain Subscale
The TWSTRS pain subscale consists of three patient-rated items that assess the participants usual, worst and best pain from the preceding week, and the subscore has a maximum of 20.
Measured: At all timepoints post injection until Week 36.
Change from baseline in the daily Numerical Rating Scale (NRS) score
The Numeric Rating Scale (NRS) is a unidimensional measure of pain intensity in adults. The NRS is a segmented numeric version of the visual analogue scale in which a respondent selects a whole number (0 to 10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").
Measured: Averaged over every 7-day period until the Week 4 visit
Time to onset of pain reduction
Defined as the duration from the administration of the study injection to the first recorded instance of a minimum 2-point decrease in the Numeric Rating Scale (NRS) score.
Measured: From study injection to first timepoint at which at least 2-point reduction is observed in NRS score
Time to return of symptoms in responders (time from treatment to loss of 80% of peak treatment effect)
As assessed by TWSTRS total score. TWSTRS scale consisting of three subscales: severity, disability and pain scales. The total score is the sum of each of the subscales, with a range of 0 to 85, where higher scores are indicative of greater impairment.
Measured: From randomization until Week 36
Change from Baseline in the TWSTRS-Disability Subscale
The TWSTRS disability subscale assesses the effect that Cervical Dystonia (CD) has on the participant's daily activities and the subscore has a maximum of 30 and consists of six items.
Measured: At all timepoints post injection until Week 36.
Change from Baseline in the TWSTRS-Severity Subscale
The TWSTRS severity subscale rates the maximal excursion of the torticollis (degree of tilt or rotation), elevation, range of motion, etc. This severity subscore has a maximum subtotal of 35 and consists of 11 items.
Measured: At all scheduled timepoints post injection until Week 36
Change from baseline in Clinical Global Impression of Severity score
The Clinical Global Impression of Severity (CGI-S) is a clinician rated scale that measures the severity of an illness in a participant. It is rated on a 7-point scale ranging from 1 (normal) to 7 (severely ill) in answer to a question on the mental state of the participant at the time of the assessment.
Measured: At all timepoints post injection until Week 36.
Clinical Global Impression of Change score
The Clinical Global Impression of Change (CGI-C) is a clinician rated scale that measures the clinical change in a participant. It is rated on a 7 point scale ranging from 1 (very much improved) to 7 (very much worse) in answer to a question on the mental state of the participant at the time of the assessment.
Measured: At all timepoints post injection until Week 36.
Change from baseline in Patients' Global Impression of Severity score
The Patient Global Impression of Severity (PGI-S) is a global index that may be used to rate the severity of a specific condition (a single-state scale). The PGI-S is a single question asking the participant to rate how their condition is now on a scale of 1 (Normal) to 4 (Severe).
Measured: At all timepoints post injection until Week 36
Patients' Global Impression of Change score
The Patient Global Impression of Change (PGI-C) is a single-item questionnaire used to measure the participant's impression of overall change in CD, in terms of activity, limitations, symptoms, emotions, and overall quality of life, since the first dose of study intervention. The measure uses a 7-point rating scale with responses ranging from "very much improved" (3) to "very much worse" (-3). Improvement is considered as very much improved, much improved, or minimally improved.
Measured: At all timepoints post injection until Week 36
Change from Baseline in the CDIP-58 total score
The Cervical Dystonia Impact Profile (CDIP-58) is a patient-based rating scale measuring the health impact of CD and contains eight subscales measuring head and neck symptoms (6 items), pain and discomfort (5 items), sleep (4 items), upper limb activities (9 items), walking (9 items), annoyance (8 items), mood (7 items), and psychosocial functioning (10 items). The total score and each subscale score have a common range of 0 (no impact) to 100 (most impact).
Measured: At all timepoints post injection until Week 36
Percentage of participants experiencing any Adverse Event (AEs) including treatment emergent adverse events (TEAEs), serious adverse events (SAEs), adverse event of special interest (AESI) and AE leading to treatment discontinuation
An Adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. TEAE is an AE for which the start date is on or after the date that the intervention began.
Measured: From baseline to Week 36.
Percentage of participants with clinically significant changes from baseline in Laboratory Parameters
Clinically significant change in laboratory parameters will be reported. The clinical significance will graded by the investigator.
Measured: At all timepoints post injection until Week 36
Percentage of Participants With Clinically Significant Changes from baseline in Vital Signs
