Registered outcomes2

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryChange in Mean Pain (NRPS) From Baseline to Endpoint in Mean Painbaseline and 13 weeks
The primary efficacy variable will be based upon an 11-point (0-10) Numeric Rating Pain Scale (NRPS), where 0 = no pain and 10 = worst possible pain, to be recorded in a patient's diary upon awakening each morning. This score should reflect the patient's mean pain over the previous 24 hours. Please note that the change from baseline to endpoint in mean pain, i.e. the difference between endpoint mean pain and baseline mean pain, which are defined as follows: * Baseline mean pain is defined as the mean of the last four available ratings of average daily pain (NRPS) in the patient diary performed in the last 7 days before randomisation. * Endpoint mean pain is defined as the mean of the last four available ratings of average daily pain in the patient diary in the last 7 days of the treatment period.
OtherChange in Mean Pain (NRPS) From Baseline to Endpoint by Total Daily Dosebaseline and 13 weeks
Details of neuropathic pain, as recorded in a subject diary, were used for the primary assessment of analgesic efficacy. Subjects assessed their pain using an 11-point (0 "no pain" to 10 "worst possible pain") NRPS upon awakening each morning and recorded the results in the subject diary. This score reflected the subject's mean pain over the previous 24 hours. Subjects were trained how to record their pain reliably. Investigators were trained in the subject's NRPS use during site initiation visits and at the investigators' meeting.
