    Sativex (Randomised Phase)
    Arm description
    Sativex was presented as an oromucosal spray. Sativex was administered by participants or caregivers to the sub-lingual or oral mucosa up to a maximum of 12 sprays per day, for 12 weeks. Each actuation delivered 100 μL (2.7 milligrams [mg] delta-9-tetrahydrocannabinol [THC] and 2.5 mg cannabidiol [CBD]). Sativex was administered as per the following titration schedule (subject to tolerability): Week 1: 1 spray every evening; Week 2: 1 spray twice daily (morning and evening); Weeks 3-4: 1 spray 3 times a day (morning, noon, and evening); Weeks 5 -6: 2 sprays 3 times a day; Weeks 7-8: 3 sprays 3 times a day; Weeks 9-12: 4 sprays 3 times a day. The maximum number of sprays at each stage of titration did not have to be reached. Participants were permitted to stop titrating at any well tolerated dose of 1–12 sprays per day.

    Sativex was presented as an oromucosal spray in an amber plastic coated glass vial. Sativex contained THC (27 mg/mL) and CBD (25 mg/mL) in ethanol:propylene glycol (50:50) with peppermint oil (0.05%) as flavouring. Each actuation delivered 100 μL (2.7 mg THC and 2.5 mg CBD) and was administered sublingually or to oral mucosa. In those participants whose disabilities made this difficult, a caregiver administered the medication. If participants complained of oral discomfort, they were advised to apply the spray to varying sites in the mouth and were not to continue spraying onto sore or inflamed mucous membranes. If lesions were observed or persistent soreness was reported, the dosing of Sativex was to be stopped until complete resolution occurred.

    Change From Baseline In Spasticity Severity 0-10 Numerical Rating Scale (NRS) Score To End Of Treatment (EOT) (12-Week Randomised Phase)
    End point description
    The spasticity 0-10 NRS was completed daily at bedtime using a study diary. The primary caregiver was asked the following question: “This question is about your child’s muscles and how soft or tight/hard they have felt today. Think carefully about how your child’s muscles have felt today and circle a number from 0 to 10 that best describes this, where: 0 = ‘my child’s muscles have felt totally relaxed’ and 10 = ‘my child’s muscles have felt the tightest/hardest they have ever felt’”. Baseline was defined as the average of the assessments recorded on Day −7 to Day −1, inclusive. EOT was the average of the last 7 days of diary data up to the earliest of Day 84, the last dose of IMP and the last day with relevant efficacy data. Least Squares Means (LS Means) were calculated using an analysis of covariance (ANCOVA) with baseline score as a covariate and treatment as fixed effect. A reduction in score indicates an improvement in condition

    Change From Baseline In Modified Tardieu Scale (MTS) Score Of The Worst Affected Limb To EOT (12-Week Randomised Phase)
    End point description
    The MTS of the worst affected limb (identified for each participant at Baseline) was assessed. Individuals were positioned in sitting position to test upper extremities and supine position to test lower extremities. MTS was based on the following criteria: • 3 speed definitions of limb movement: V1 (as slow as possible), V2 (falling under gravity), V3 (as fast as possible) • MTS describes R1 and R2: R1 is the angle of muscle reaction; R2 is the full passive range of movement. • R2 was measured at V1 and R1 at V3. R2-R1 = dynamic tone component of the muscle. The relationship between R1 and R2 estimates the relative contributions of spasticity compared to contracture. EOT was defined Day 84. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect; using Last observation carried forward (LOCF) if observations were missing at EOT. A reduction in score indicates an improvement in condition.

    This trial assessed the MAS of the main muscle groups of the upper and lower limb using the MAS Examination and Scoring System. The MAS was performed by the same examiner at each clinic visit (where possible), with the participant in the supine position and the participant was requested to relax. If a muscle that primarily flexed a joint was tested, the joint was placed in a maximally flexed position and moved to a position of maximal extension in 1 second (counted ‘one thousand one’). If a muscle that primarily extended a joint was tested, the joint was placed in a maximally extended position and moved to a position of maximal flexion in 1 second (counted ‘one thousand one’). EOT was defined as Day 84. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect; using LOCF if observations were missing at EOT. A reduction in score indicates an improvement in condition.

    End point description
    Sleep quality was assessed using a 0-10 NRS questionnaire completed at the same time each day, ideally when waking in the morning. This questionnaire was designed to record the level of sleep disturbance. The primary caregiver was asked the following question: “This question is about how badly your child slept last night. Please mark a number from 0 to 10 that indicates how bad your child’s sleep was, where a score of 0 indicated "My child had a night of non-stop sleep" and a score 10 indicated "My child was unable to sleep at all.” EOT is the average of the last 7 days of diary data up to the earliest of Day 84, the last dose of IMP and the last day with relevant efficacy data. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect. A reduction in score indicates an improvement in condition.

    Change From Baseline In Paediatric Pain Profile (PPP) Score To EOT (12-Week Randomised Phase)
    End point description
    The PPP is a 20-item behaviour rating scale designed to assess pain in children with severe neurological disability. Each item was scored on a 4-point scale of 0 to 3 as occurring ‘not at all’ (zero) to ‘a great deal’ (three) in the given time period. Therefore, the total score ranged from 0 to 60. The questionnaire was designed to be completed by the child’s primary caregiver and was completed at each assessment visit during the trial. EOT was defined as Day 84. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect; using Last observation carried forward (LOCF) if observations were missing at EOT. A reduction in score indicates an improvement in condition.

    Change From Baseline In Cerebral Palsy Quality Of Life (CP QOL) Score To EOT (12-Week Randomised Phase)
    End point description
    CP QOL-child (4-12 years old) questionnaire assessed the following domains of life: social wellbeing and acceptance, feelings about functioning, participation and physical health, emotional wellbeing and self-esteem, access to services, pain and impact on disability, family health. CP QOL-teen (13-18 years old) questionnaire completed by the participant (if possible) assessed the following domains of life: feelings about functioning, access to services, general wellbeing and participation, communication and physical health, school wellbeing, social wellbeing. Scores from both questionnaires were transformed to a 0–100 scale. Domain scores were calculated by taking the average of the converted question response scores for the questions included in that domain. EOT was Day 84. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect; using LOCF if observations were missing at EOT. Increase in score indicates improvement in condition.

    Change From Baseline In Comfort Questionnaire Outcome To EOT (12-Week Randomised Phase)
    End point description
    The comfort questionnaire was completed at the same time each day, that is, bedtime in the evening. The caregiver was asked to reflect on the whole day and record the longest number of minutes at any 1 time during which their child was able to sit in comfort for, without moving position. Baseline was defined as the average of Day −7 to Day −1. EOT was the average of the last 7 days of diary data up to the earliest of Day 84, the last dose of IMP and the last day with relevant efficacy data. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect. An increase in time indicates an improvement in condition.

    Change From Baseline In Children's Depression Inventory (CDI) 2 Score To EOT (12-Week Randomised Phase)
    End point description
    The CDI 2 contains 12 items, each of which consists of 3 statements (each scored 0-2 [0=best outcome, 2=worst outcome]). For each item, the participant was asked to select the statement that best describes his or her feelings. The assessment addressed a variety of situations, including schools, child guidance clinics, paediatric practices, and child psychiatric settings. If the participant was unable to complete the questionnaire, the questionnaire was left blank. All CDI 2 forms were administered and scored using the Multi-health System Inc. QuikScore™ format. Each QuikScore form included conversion tables, which were used to convert raw scores to T-scores. EOT was defined as Day 84. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect; using LOCF if observations were missing at EOT. A reduction in T-score indicates an improvement in condition.

    The SF-36-II is a 36 item questionnaire that measures 8 multi-item dimensions of health: physical functioning (10 items) social functioning (2 items) role limitations due to physical problems (4 items), role limitations due to emotional problems (3 items), mental health (5 items), energy/vitality (4 items), pain (2 items), and general health perception (5 items). There is a further unscaled single item asking respondents about health change over the past year. For each dimension item scores were coded, summed, and transformed on to a scale from 0 (worst possible health state measured by the questionnaire) to 100 (best possible health state). EOT was defined as Day 84. LS Means were calculated using ANCOVA with baseline score as a covariate and treatment as fixed effect; using LOCF if observations were missing at EOT. An increase in score indicates an improvement in condition.

    Caregiver Global Impression Of Change (CGIC) Response On Participants General Functional Capabilities At Last Visit (12-Week Randomised Phase)
    End point description
    The main caregiver was asked to assess the change in the participant’s condition. At Visit 2 (Baseline) carers were asked to write a brief description of the participant’s general functional abilities. This acted as a memory aid that the carer could refer to when answering the CGIC question at later time points in the trial. The caregiver was asked, ”How have the participant’s general functional abilities changed since Visit 2?” (Baseline). The question was rated on a 7-point scale: Very much worse, Much worse, Minimally worse, No change, Minimally better, Much better, Very much better. The number of participants for each marker is presented.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    04 Mar 2015
    - A change in an inclusion no longer requires participants to currently be on spasticity therapy as paediatric participants are less likely than adults to continue on medications that are not sufficiently alleviating their symptoms or if side effects occur. The protocol amendment now required participants to have received inadequate efficacy and/or experienced unacceptable side effects from previous or current treatment with at least one of the following medications for spasticity: Baclofen, diazepam (or another benzodiazepine), dantrolene, tizanidine, gabapentin and trihexyphenidyl. - A parental/legal representative can withdraw participant assent/consent. -Before any open-label procedures are performed, the Investigator must reiterate the known adverse reactions to Sativex and ensure participants and parents/legal guardians are fully informed of the trial requirements. The signed informed consent/assent forms can be referred to for this. Participants who decline will receive a follow up telephone call 14 days after the end of treatment to check for AEs and concomitant medication changes. - If a participant does not possess adequate understanding, assent will be taken along with parental/legal representative consent. The investigator should also give consideration to a child's wishes not to participate, or wishes to withdraw at any time during the trial regardless of their level of understanding and regardless of parental/legal representative consent.
