  10. In good health (i.e. absence of any uncontrolled systemic disease or other significant medical condition) as determined by medical history, physical and neurological examinations, clinical laboratory studies, electrocardiograms (ECGs), vital signs, and Investigator's judgment prior to randomization

  11. Male and female participants Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

Male participants must agree that, if their partner is at risk of becoming pregnant, they will use an effective method of contraception. The participants must agree to use the contraception during the whole period of the study.

A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies: Is a woman of non-childbearing potential (WONCBP) or is a woman of childbearing potential (WOCBP) and using an acceptable contraceptive method (until the end of the study). The investigator should evaluate the potential for contraceptive method failure in relationship to the first dose of study intervention. A WOCBP must have a negative highly sensitive pregnancy test.

Exclusion Criteria
  1. Any medical condition (including severe dysphagia or airway disease) that may increase, in the opinion of the investigator, the likelihood of adverse events (AEs) related to BoNT treatment.
  2. Known disease of the neuromuscular junction (e.g. Lambert-Eaton myasthenic syndrome, myasthenia gravis or amyotrophic lateral sclerosis etc.).
  3. Has a history of hypersensitivity to the investigational medicinal products (or other BoNTs) or any excipient used in their formulation.

  5. Likely treatment with any serotype of BoNT for any condition during the study.
  6. Undergone previous surgery to treat spasticity in the affected upper limb.
  7. Has initiated physiotherapy within 30 days prior to Baseline (if physiotherapy initiated more than 30 days prior to Baseline and ongoing, the therapy regimen should be maintained at the same frequency and intensity throughout the study if possible or at least up to 3-months post-injection).

  11. Use of concomitant therapy which, in the investigator's opinion, would interfere with the evaluation of the safety or efficacy of the study intervention, including medications affecting bleeding disorders. For patients taking vitamin K antagonists, the INR values should be controlled (between 2 and 3)
  12. Currently planned or a history of tendon lengthening surgery, significant contracture or muscle atrophy at target joint or muscle in the past 6 months prior to Screening.
  13. Use of any experimental device within 30 days or use of any treatment with an experimental drug within five times the documented terminal half-life of the respective drug or its metabolites or if the half-life is unknown within 30 days prior to the start of the study (prior to Baseline) and during the conduct of the study.
  14. Presence of any other condition (e.g. neuromuscular disorder, muscular dystrophies, cancer cachexia, sarcopenia or other disorder that could interfere with neuromuscular function), laboratory finding or circumstance that, in the judgment of the investigator, might increase the risk to the participant or decrease the chance of obtaining satisfactory data to achieve the objectives of the study.
  15. Pregnant or lactating women, or women of childbearing potential not willing to practice a highly effective form of contraception method at the beginning of the study, for the duration of the study and for the duration of the study
  16. Inability to understand protocol procedures and requirements
  17. Infection at the injection site(s)
  18. A history of drug or alcohol abuse
  19. Male participants who are not vasectomised and who have female partners of childbearing potential and are not willing to use condoms with spermicide throughout study participation.

Dose escalationDysportOne single administration of study medication (IPN10200, Dysport or placebo) will be injected in a dose-escalation manner. Dose-escalation will include several cohorts.
Total dosePlaceboOne 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 IPN10200 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 (IPN10200 lower dose: 30 participants; placebo: 10 participants, then IPN10200 higher dose: 30 participants; placebo: 10 participants, resulting in a total of 80 participants in Stage 3).

Secondary Outcome Measures
NameTimeMethod
Change from Baseline in MAS score in all injected muscle Groupsfrom 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).from baseline until the end of study (9 months)
Peak of effect - maximal decrease in the MAS score from Baseline.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).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.from baseline until the end of study (9 months)
Physician's Global Assessment (PGA) score of overall treatment responsefrom baseline until the end of study (9 months)

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.

Patient Global Impression of Change in the Spastic Clinical Pattern using specific scale (PGI-c)from baseline until the end of study (9 months)

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

The number and percentage of participants with presence of IPN10200 and BoNT-A antibodies and titres (binding and neutralising)At baseline
Change from Baseline in the Disability Assessment Scale (DAS)from baseline until the end of study (9 months)

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.

Change from Baseline to post-treatment Day 29 in MAS score in the PTMGfrom baseline until port-treatment Day 29

if PD profile of IPN10200 in dose escalation indicates a peak of effect different than Day 29, the endpoint will be modified accordingly)
