Sativex and rifampicin

The spasticity 0-10 NRS was completed daily at bedtime using a paper study diary. The difference between spasticity and spasm was clearly explained to the caregiver. 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'". A reduction in score indicates an improvement in condition. The mean spasticity 0-10 NRS score of the last 7 days of the baseline period was used for a patient's mean baseline score. The mean 0-10 NRS score of the last 7 days prior to completion/withdrawal was used for a patient's mean end of treatment score.

Subjects were asked "On a scale of '0 to 10' please indicate the average level of your spasticity over the last 24 hours" with the anchors: 0 = 'no spasticity' and 10 = 'worst possible spasticity'. They were asked to relate 'no spasticity' to the time prior to the onset of their spasticity.

The time to treatment failure was calculated as the number of days from the first day of treatment up to the day of treatment failure. The day of treatment failure was the earliest of:the day of premature cessation of study medication;the first day of the longest period, ending on the last day of treatment, where the mean spasticity NRS had increased by at least 20% and at least 1 unit from the treatment baseline; the day of a clinically relevant increase in anti-spasticity or disease modifying medication. The number of subjects who failed treatment were calculated.

The pain severity Numerical Rating Scale was complete at the same time each day, i.e. bedtime in the evening. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain severity in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of neuropathic pain. A negative value indicates an improvement in pain score from baseline.

The pain NRS was completed at the same time each day, i.e. bedtime in the evening. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of pain due to multiple sclerosis. A negative value indicates an improvement in pain score from baseline.

A positive 30% pain response is defined as a reduction of at least 30% in the mean NRS pain score from baseline to week 14 (last 7 days). The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of pain due to multiple sclerosis. The pain NRS was completed at the same time each day, i.e. bedtime in the evening.

The average pain NRS was complete at the same time each day, i.e. bedtime in the evening. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain or average pain in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of pain. A negative value indicates an improvement in pain score from baseline.

The peripheral neuropathic pain NRS was completed at the same time each day, i.e. bedtime in the evening. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain or average pain in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of pain. A negative value indicates an improvement in pain score from baseline.

The diabetic neuropathy pain Numerical Rating Scale was complete at the end of every day. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your nerve pain due to diabetes in the last 24 hours" where 0 = no pain and 10 = worst possible pain. No pain relates to the time prior to the onset of pain due to diabetic neuropathy. For those whose evaluable period ended before Day 7, the mean of the available post-randomisation data was used. Those with no post-baseline diary pain 0-10 Numerical Rating Scale scores were excluded from the analysis.

A positive 30% pain response is defined as a reduction of at least 30% in the mean NRS average pain score from baseline to week 14 (last 7 days). The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain or average pain in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of pain. The average pain NRS was completed at the same time each day, i.e. bedtime in the evening. Estimates were produced for a one-week period, with the evaluable period finishing at the end of the appropriate seven-day period.

The average spasticity NRS was completed at the same time each day, i.e. bedtime in the evening. The subject was asked "on a scale of '0 to 10', please indicate the number that best describes your spasticity in the last 24 hours" where 0 = no spasticity and 10 = worst possible spasticity. A negative value indicates an improvement in pain score from baseline.

To assess the effect of Sativex in neurogenic overactive bladder, the incontinence episode frequency was selected as the primary endpoint. Baseline was the average of all available data recorded during the 14 days immediately prior to the randomisation visit. End of Treatment was the last average available from Week 3, Week 5, and Weeks 7-8. A negative value indicates an improvement in score from baseline.

The spasticity Numerical Rating Scale was completed at the same time each day, i.e. bedtime in the evening. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your average spasticity in the last 24 hours" where 0 = no spasticity and 10 = worst ever spasticity. For the analysis, end of treatment was defined as the mean of the last seven days in the study or the last three days if the subject withdrew due to worsening spasticity or lack of efficacy. A negative value indicates an improvement in spasticity score from baseline.

The neuropathic pain Numerical Rating Scale was completed at the same time each day, i.e. bedtime in the evening. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain or average pain in the last 24 hours" where 0 = no pain and 10 = worst possible pain. A negative value indicates an improvement in pain score from baseline.

All blood samples will be taken by either direct venipuncture or an indwelling cannula inserted in a forearm vein. For pharmacokinetic (PK) assessments, blood will be drawn from each patient into a five mL lithium-heparinised tube at the following intervals (±five min): Pre-dose (0),0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9, 11, 24, 36 and 48 hours post dose.
