Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age ≥ 18 years.
  • Spastic Cerebral Palsy.
  • Chronic pain, related to spastic muscle. Chronic pain defined as: 1)Recurring regional pain for at least three months AND 2)Pain intensity on average for the last 24 hours ≥3 on Numerical Rating Scale.
  • Signed Informed consent.

Exclusion Criteria:

  • Allergy/hypersensitivity to Dysport® or any of its components.
  • Pregnancy.
  • Women who breastfeed their children.
  • Treatment with Botulinum toxin-A within the last five months.

  • A clear degenerative cause behind the pain as elucidated by the clinical examination (e.g. history of osteoarthritis).
  • Intellectual disability and/or communication impairment that disable the individual from answering the questionnaires and giving informed consent.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain intensity
Time Frame: Six weeks after treatment
Proportion of responders derived as reduction of intensity of pain of ≥2 points on the Numerical Rating Scale (NRS) at Visit 3 (six weeks after treatment) compared to baseline.
Six weeks after treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Use of other analgesic treatment
Time Frame: Six weeks after treatment
Categories of change in the use of analgesic treatments, derived as Increase, No change, or Decrease at Visit 3 (six weeks after treatment), compared to baseline.
Six weeks after treatment
Pain interference
Time Frame: Six weeks after treatment
Proportion of responders derived as a reduction in mean interference score of ≥1 on the Brief Pain Inventory (BPI-SF) at Visit 3 (six weeks after treatment) compared to baseline.
Six weeks after treatment

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
HRQoL (Health-Related Quality of Life)
Time Frame: Six weeks after treatment
Mean change at Visit 3 (six weeks after treatment) compared to baseline in the Short Form 36 v2 Health-related Quality of Life questionnaire (SF-36v2)
Six weeks after treatment
Global Impression of Change
Time Frame: Six weeks after treatment
Proportion of responders at Visit 3 (six weeks after treatment) in the Global Impression of Change Scale (PGIC) derived as at least "Minimally improved".
Six weeks after treatment
Fatigue Severity Scale
Time Frame: Six weeks after treatment
Proportion of responders at Visit 3 (six weeks after treatment) in the Fatigue Severity Scale (FSS) derived as a reduction in mean score of ≥1 point.
Six weeks after treatment
Spasticity
Time Frame: Six weeks after treatment
Proportion of responders at Visit 3 (six weeks after treatment) derived as achieving reduction of spasticity of >1 scale steps on the Modified Ashworth Scale (MAS)
Six weeks after treatment
Range of Motion
Time Frame: Six weeks after treatment
Proportion of responders at Visit 3 (six weeks after treatment) derived as improvement in passive joint range of motion (ROM) ≥ 10 degrees.

Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
