Prospective, open-label, non-randomized, single-arm, dose titration, phase II study. The study will consist of three injection cycles. In each, an injection visit is followed by an observation period of 12 to 20 weeks. During cycle 1, a total body dose of 16U/kg (maximum 400U) of IncobotulinumtoxinA will be injected into the spastic muscles of the affected limbs. During cycle 2, a total body dose of 19U/kg (maximum 475U) of IncobotulinumtoxinA will be injected into the spastic muscles of the affected limbs. If a dose of 19U/kg is not justified (i.e., for clinical or safety reasons) but BoNT-A treatment is still needed (according to the clinical condition of patients) the same dose injected in cycle 1 (16U/Kg; maximum 400U) may be administered in the cycle 2. During cycle 3, a total body dose of 22U/kg (maximum 550U) of IncobotulinumtoxinA will be injected into the spastic muscles of the affected limbs. If a dose of 22U/kg is not justified (i.e., for clinical or safety reasons) but BoNT-A treatment is still needed (according to the clinical condition of patients) the same dose injected in cycle 2 (19U/Kg; maximum 475U) may be administered in the cycle 3.

Primary | Ashworth Scale | The Ashworth scale is a well-known and commonly used scale in clinical trials with spasticity. It will be used to categorize the severity of spasticity by judging resistance to passive movement. It is a 5-point scale that ranges from 0 (=no increase in tone) to 4 (=limb rigid in flexion or extension). | During the screening assessment | |

Secondary | REsistance to PAssive movement Scale (REPAS) | The REPAS is a summary 26-item test used to assess resistance to passive movement in all four limbs of the body. It provides a global evaluation of spasticity status, as well as per hemibody and per limb. 16 items describe the condition of both upper limbs, 10 that of both lower limbs. Each item is rated by using the AS. The sum of the values represent the REPAS score which may range from zero (no resistance for any item) to 104 (limbs rigid for all items). | Immediately before each IncobotulinumtoxinA treatment session; at the follow-up clinical assessment at 4 and 12 weeks from each injection | |
Secondary | Gross Motor Function Classification System (GMFCS) | Is a 5 level classification system that describes the gross motor function of people with cerebral palsy (I=can walk indoors and outdoors and climb stairs without using hands for support; II=can climb stairs with a railing, has difficulty with uneven surfaces, inclines or in crowds; III=walks with assistive mobility devices indoors and outdoors on level surfaces, may be able to climb stairs using a railing, may propel a manual wheelchair and need assistance for long distances or uneven surfaces; IV=walking ability severely limited even with assistive devices, uses wheelchairs most of the time and may propel own power wheelchair, standing transfers, with or without assistance; V=has physical impairments that restrict voluntary control of movement, ability to maintain head and neck position against gravity restricted, impaired in all areas of motor function, cannot sit or stand independently, even with adaptive equipment). | During the screening assessment; immediately before each IncobotulinumtoxinA treatment session; at the follow-up clinical assessment at 4 and 12 weeks from each injection | |
Secondary | Visual Analog Scale (VAS) | The VAS, which is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain." | Immediately before each IncobotulinumtoxinA treatment session; at the follow-up clinical assessment at 4 and 12 weeks from each injection | |
Secondary | Goal Attainment scale (GAS) | The GAS measures the extent to which a subject's individual goals are achieved in course of intervention. The subject and treating team have to identify 2 personal goals for each treated limb at each injection cycle. Investigator rates the GAS score for each injection cycle. The degree of goal attainment is rated on a 5-point scale (-2, -1, 0, +1, +2; study baseline set to -1) and in order to account for interindividual differences in the number of goals (positive values indicate higher goal attainment). | Immediately before each IncobotulinumtoxinA treatment session; at the follow-up clinical assessment at 4 and 12 weeks from each injection | |
Secondary | Global Assessment of Efficacy | The Global Assessment of Efficacy, which will be assessed by the investigator, the patient (if possible), and the caregiver using a 4-point Likert scale with the ratings 1 = very good, 2 =good, 3 = moderate, and 4 = poor. | At the follow-up clinical assessment at 4 and 12 weeks from each injection | |
Secondary | Global Assessment of Tolerability | The Global Assessment of Tolerability, which will be assessed by the investigator at each injection cycle control [V3, V6, V9] and end of cycle visits [V4, V7, V10] using a 4-point Likert scale with the ratings 1 = very good, 2 = good, 3 = moderate, and 4 = poor. | At the follow-up clinical assessment at 4 and 12 weeks from each injection |
