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

ListOutcomeTime frameDescription
PrimaryChange in Average Pain Intensity Measured by the Change in Pain Intensity-Numeric Rating Scale (PI-NRS) Scores From Randomization Baseline to Week 12 of the Double-blind Maintenance PhaseRandomized Baseline through Week 12The PI-NRS is an 11-point numerical rating scale ranging from 0 (no pain) to 10 (worst possible pain).
SecondaryTime-to-exit From the Study for All CausesRandomization Baseline through Week 12
Survival analysis. Measure type indicated as 'Number' below represents 25% quartile, given that the median was not reached. These data are consistent with subject completion in the Participant Flow module.
SecondaryPercent Reduction in Pain Intensity for RespondersScreening Baseline through Week 12
Includes the cumulative distribution of subjects with an improvement in pain intensity, as measured on an 11-point PI-NRS scale, and the proportion of responders with at least 30% and at least 50% reduction in pain intensity.
SecondaryWeekly Changes in Pain IntensityRandomization Baseline and weekly through Week 12
Weekly pain intensity scores were calculated based on averaged daily pain intensity scores (PI-NRS). Increases to the weekly change in pain intensity, correspond to increases in the PI-NRS scores (i.e. more pain).
SecondaryRescue Medication Usage by DoseRandomization Baseline through Week 12Evaluation of the total amount of rescue medication used (number of doses per day, number of doses per week, and total number of doses while on-study)
SecondaryRescue Medication Use by DosageRandomization Baseline through Week 12Evaluation of the total amount of rescue medication used (by milligrams of dosage per day, dosage per week, and total dosage while on-study)
SecondaryPatient Global Impression of Change (PGIC)Screening Baseline through Week 12
The PGIC scale is a self-reported assessment that assesses a subject's impression of his/her change in activity limitations, symptoms, emotions, and the overall quality of life as they relate to his/her painful condition. The 7-point PGIC assessment includes "very much improved", "improved", "a little improved", "no change", "a little worse", "worse", and "very much worse".
SecondaryChanges in Quality of LifeRandomization Baseline through Week 12
Short Form 12 Question Health Survey version 2 (SF-12v2) is a self-report survey designed to measure general quality of life from the subject's point of view. The survey includes eight domains: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health. Physical (PCS) and mental component scores (MCS) are also calculated. Positive values indicate improvement from randomization baseline to Week 12.
SecondaryChange in Level of Physical Disability Using the Roland Morris Disability Questionnaire (RMDQ)Randomization Baseline and Week 12
The Roland Morris Disability Questionnaire (RMDQ) is a self-administered questionnaire designed to assess physical disability caused by lower back pain. The RMDQ contains 24 sentences that subjects used to describe themselves when they have back pain. The RMDQ score is the total number of items checked which is from a minimum of 0 to a maximum of 24; the greater the score the grater the physical disability due to lower back pain.
