Primary Outcome Measures :
  1. Change From Baseline to 13 Week Endpoint in Brief Pain Inventory (BPI) Modified Short Form-adolescent Version 24 Hour Average Pain Severity Item [ Time Frame: Baseline, 13 weeks ]

    Brief Pain Inventory (BPI) modified short form is a self-reported scale that measures the severity of pain and the interference of pain on function, Severity scores range from 0 (no pain) to 10 (pain as bad as you can imagine). Severity of pain is measured based on the average pain experienced over the past 24-hours.

    Mixed Model Repeated Measure (MMRM) model with terms for treatment, pooled investigator, visit, baseline, treatment by visit, and baseline by visit was used to produce Least Square (LS) means.



Secondary Outcome Measures :
  1. Change From Baseline to 13 Week Endpoint in Brief Pain Inventory (BPI) Modified Short Form-Adolescent Version Severity and Interference Items [ Time Frame: Baseline, 13 weeks ]

    The Brief Pain Inventory (BPI) - Modified Short Form Adolescent Version is a self-reported scale that measures the severity of pain and the interference of pain on function. The Severity scores range from 0 (no pain) to 10 (pain as bad as you can imagine).There are 4 questions assessing the severity for worst pain, least pain, average pain in the past 24 hours (which is the primary efficacy measure), and the pain right now. The Interference scores range from 0 (does not interfere) to 10 (completely interferes). There are 7 original questions assessing the interference of pain in the past 24 hours on the following: general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life. The BPI: Adolescent Version added an eighth interference question to assess interference of pain on school work.

    MMRM model with terms for treatment, pooled investigator, visit, baseline, treatment by visit, and baseline by visit was used to produce LS means.


  2. Maintenance Effect in Acute Phase Responders on the Brief Pain Inventory (BPI) Modified Short Form-adolescent Version 24 Hour Average Pain Severity Item [ Time Frame: Baseline (Extension Phase), 39 weeks ]

    Brief Pain Inventory (BPI) modified short form is a self-reported scale that measures the severity of pain and the interference of pain on function.Severity scores range from 0 (no pain) to 10 (pain as bad as you can imagine).

    Acute phase responders: Participants with ≥30% pain reduction from baseline on the BPI average pain severity measure at the last non-missing assessment in acute phase.


  3. Number of Participants With Greater Than or Equal to 30% Reduction From Baseline in BPI 24 Hour Average Pain Severity Score at 13 Weeks [ Time Frame: 13 weeks ]

    Brief Pain Inventory (BPI) modified short form is a self-reported scale that measures the severity of pain and interference of pain on function, Severity scores range from 0 (no pain) to 10 (pain as bad as you can imagine).

The severity scores range from 0 (no hurting, no discomfort, no pain) to 100 (hurting a whole lot, very uncomfortable, severe pain).

    Analysis of Covariance (ANCOVA) model with last observation carried forward (LOCF) was used to produce LS means with terms for treatment, pooled investigator and baseline value.

    Clinical Global Impression of Severity: Overall Illness (CGI-S: Overall Illness) scale evaluates the severity of the overall illness of JPFS, including all relevant, associated symptoms. The scoring ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill participants). The scoring is based on observed and reported symptoms and behaviors over the past 7 days that are ongoing at the time of the Study Visit.

    Analysis of Covariance (ANCOVA) model with last observation carried forward (LOCF) was used to produce LS mean with terms for treatment, pooled investigator and baseline value.


  7. Change From Baseline in Clinical Global Impression (CGI) Severity: Mental Illness Score [ Time Frame: Baseline, 13 weeks ]
