DysportBiological
Powder for solution for injection
| Study group | Role | What they receive |
|---|---|---|
| Dose escalation | Experimental | One single administration of study medication (Corabotase, Dysport or placebo) will be injected in a dose-escalation manner. Dose-escalation will include several cohorts. Receives: Biological: Corabotase; Drug: Placebo; Biological: Dysport |
| Dose ranging | Experimental | Two fixed doses of Corabotase will be administrated as a single injection into several muscle groups of the upper limb.
Participants will be randomised in the ratio of 3:3:2 (total Corabotase dose 1: 30 participants; total Corabotase dose 2: 30 participants; Dysport: 20 participants) Receives: Biological: Corabotase; Biological: Dysport |
| Total dose | Experimental | One single injection of study medication will be administered locally into several muscle groups of the upper limb.
Participants will be randomized in the ratio of 2:1 (Total Corabotase dose: 30 participants; placebo: 15 participants, resulting in a total of 45 participants in Stage 3).
Or
Participants will be randomized in the ratio of 3:1 (Corabotase lower dose: 30 participants; placebo: 10 participants, then Corabotase higher dose: 30 participants; placebo: 10 participants, resulting in a total of 80 participants in Stage 3). Receives: Biological: Corabotase; Drug: Placebo |

The primary outcome is the main question the study is designed to answer.
Percentage of participants with treatment emergent adverse events (TEAEs).
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.
Measured: From baseline until the end of study (9 months)
Percentage of participants with adverse events of special interest (AESI).
Measured: From baseline until the end of study (9 months)
Change from baseline in vital sign parameter (blood pressure)
Measured: 9 months
Change from baseline in vital sign parameter (Heart rate)
Measured: 9 months
Change from baseline in clinical laboratory test results.
Number and percentage of participants with low, normal or high values and normal or abnormal examinations will be presented.
Measured: 9 months
Presence of IPN10200 and BoNT-A antibodies (binding and neutralising)
Measured: From baseline until the end of study (9 months)
Change from baseline in physical examination findings.
Number of Participants with change in physical examination findings
Measured: 9 months
Secondary outcomes (14)
Change from Baseline to all post-treatment visits in Modified Ashworth scale (MAS) score in the Primary target muscle group (PTMG)
MAS is a scale to assess muscle tone in the injected muscles. The muscle tone will be rated as per grading from 0 to 4, there 0 =No increase in muscle tone and 4 =Affected part(s) rigid in flexion or extension.
Measured: from baseline until the end of study (9 months)
Change from Baseline to post-treatment Day 29 in MAS score in the PTMG.
If PD profile of IPN10200 in dose escalation indicates a peak of effect different than Day 29, the endpoint will be modified accordingly)
Measured: From baseline until post-treatment Day 29
Change from Baseline in MAS score in all injected muscle Groups
Measured: From baseline until the end of study (9 months)
Time to onset - time to the response to treatment (a reduction of at least one grade in the MAS score).
Measured: From baseline until the end of study (9 months)
Peak of effect - maximal decrease in the MAS score from Baseline.
Measured: From baseline until the end of study (9 months)
Time to peak - time to reach the peak of effect (maximal decrease in the MAS score from Baseline).
Measured: From baseline until the end of study (9 months)
Duration of effect - duration between time to onset and last timepoint with a response to Treatment.
Measured: From baseline until the end of study (9 months)
Response to treatment as measured by at least one grade reduction in MAS score in the PTMG from Baseline
Measured: From baseline until the end of study (9 months)
Response to treatment as measured by at least one grade reduction in MAS score in all injected muscles from Baseline
Measured: From baseline until the end of study (9 months)
Physician's Global Assessment (PGA) score of overall treatment response
The PGA is a 9-point scale (from -4= markedly worse to +4=markedly improved) used to assess global overall treatment response by the investigator.
Measured: From baseline until the end of study (9 months)
Patient Global Impression of Change in the Spastic Clinical Pattern using specific scale (PGI-c)
PGI-C is a scale to assess global impression of change in the spastic clinical pattern using a 7-point Likert scale (from -3: very much worse to +3: very much improved) by answering a specific question
Measured: from baseline until the end of study (9 months)
Change from Baseline in the Disability Assessment Scale (DAS)
The DAS will be used to assess the effect of upper limb spasticity on hygiene, dressing, limb position and pain. Participants will be assessed in an interview format.
Measured: From baseline until the end of study (9 months)
Reduction of pain in the shoulder (adducted/rotated pattern) using the Numeric Rating Scale
Measured: From baseline until the end of study (9 months)
The number and percentage of participants with presence of IPN10200 and BoNT-A antibodies and titres (binding and neutralising)
Measured: At baseline

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Corabotase and Dysport in people with Spasticity, run by Ipsen at 81 sites in 14 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 16 inclusion and 19 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: looking for participants now, as of the sponsor's last update on 28 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 81 sites in Poland, Germany, Spain, Czechia, Russia and 9 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ipsen Recruitment Enquiries (see email, clinical.trials@ipsen.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of participants with treatment emergent adverse events (TEAEs). (time frame: From baseline until the end of study (9 months)). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jul 2026.
