Study Endpoints

Primary Endpoints

Change From Baseline in Mean Central Neuropathic Pain 11-Point Numerical Rating Scale Scores at the End of Treatment (up to 51 Days).
Up to 51 days

The Central Neuropathic Pain Numerical Rating Scale score was recorded three times daily, in the morning (on waking), at lunchtime and in the evening using the scale, 0 = 'No Pain' and 10 = 'Worst Possible Pain'. Patients were instructed to relate 'No Pain' to the time before the start of their spinal cord injury. End of Treatment was defined as the mean of the last seven days in the study or the mean of the last three days if the subject withdrew. A negative value indicates an improvement in pain score from baseline.

Change From Baseline in Mean Pain Box Scale-11 Score at 3 Weeks.
0 - 3 weeks

Each day, in the morning (on waking), at lunchtime and in the evening (just before going to bed), patients recorded in their patient diary their level of pain using a Box Scale-11 pain score ranging from zero "no pain" to 10 "worst possible pain". Week 3 analysis was defined as the mean of the last seven days in the study. The last day was taken as the last day with complete diary card pain data that occurred on or before the last day the patient took study medication. A negative value from baseline indicates and improvement.

Incidence of Adverse Events as a Measure of Subject Safety.
Up to 1051 days

Following data entry, all adverse events were medically encoded using the Medical Dictionary for Regulatory Activities (MedDRA) 6.0. All subjects who experienced an adverse event during the treatment period is presented.

Change From Baseline in the Mean Box Scale-11 Pain Review Score at the End of Each Treatment Period (Each Lasting 14-20 Days)
Up to 74 days

Each day patients recorded in their patient diary, the severity of their pain during the previous 24 hours using a Box Scale-11 pain score ranging from zero "no pain at all" to 10 "pain as bad as you can imagine". The Box Scale-11 pain score endpoint for each assessment period was the average of all available data recorded during the seven whole days prior to the visit immediately subsequent to that period, but only including data from Day 8 onwards. A negative value indicates an improvement in pain score from baseline.

Incidence of Adverse Events as a Measure of Patient Safety
up to1206 days

The number of patients who experienced an adverse event during the course of this extension study is presented

Change From Baseline in Composite Primary Impairment Visual Analogue Scale Score at the End of 6 Weeks of Treatment
baseline and 6 weeks

This was achieved by measuring the change from baseline after six weeks of therapy in the severity of the primary impairment, a composite score from one of five Multiple Sclerosis symptom categories that subjects nominated as their most severe symptom. The severity scores were recorded using a 100 mm Visual Analogue Scale, where 0 = no problem and 100 = very bad. A decrease in score indicates an improvement.

Change From Mean Part A Primary Impairment Visual Analogue Scale Score (After 6 Weeks) at the End of Four Weeks of Open-label Treatment (10 Weeks Total)
End of Part A (week 6) - end of Part B (week 10 [4 weeks total open-label treatment])

This was achieved by measuring the change in the Part A study score (mean of all scores during the last two weeks of six weeks of double-blind therapy) in the severity of the primary impairment (mean of all scores during the last two weeks of four weeks of open-label therapy), a composite score from one of five multiple sclerosis symptom categories that subjects nominated as their most severe symptom. The severity scores were recorded using a 100 mm Visual Analogue Scale, where 0 = no problem and 100 = very bad. As such, a decrease in score indicates an improvement and a negative value indicates an improvement in score from baseline.

Secondary Endpoints

Change From Baseline in the Mean Percentage of Days on Which Escape Medication Was Used at the End of Treatment
Up to 51 days
Change From Baseline in Mean Spasm Severity Numerical Rating Scale Score at the End of Treatment
Up to 51 days
Change From Baseline in the Percentage of Days on Which Spasm Was Experienced at the End of Treatment
Up to 51 days
