Outcomes
Primary Outcome Measures
Incidence of Adverse Events as a Measure of Subject Safety.
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.
Secondary Outcome Measures
Change From Parent Study Baseline in Spasticity 0-10 Numerical Rating Scale Score After 52 Weeks of Treatment.
Subjects were asked to rate the severity of their primary symptom each week in the diary using an 11-point Numerical Rating Scale, where zero = "best possible" and 10 = "worst possible". A negative value indicates an improvement in score from baseline.
Change From Parent Study Baseline in Central Neuropathic Pain 0-10 Numerical Rating Scale Score at 52 Weeks of Treatment.
Subjects were asked to rate the severity of their primary symptom each week in the diary using an 11-point Numerical Rating Scale, where zero = "best possible" and 10 = "worst possible". A negative value indicates an improvement in score from baseline.

5. Study Description
Brief Summary
Subjects who had previously received GW-1000-02 in a GW study who opted to continue using it in the long-term were monitored for ongoing tolerability and evidence of clinical benefit.
Detailed Description
Subjects who had previously participated in a placebo controlled GW clinical study were screened and if eligible began dosing with GW-1000-02. Subjects were reviewed for tolerability and evidence of clinical benefit at weeks two and four and then every eight weeks. Subjects self-titrated to symptom resolution or maximum tolerated/allowable dose of 130 mg THC and 120 mg CBD.
