Further study details as provided by Stanford University:

Primary Outcome Measures:
  • Visual Analog Scale [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    intrapatient comparisons of Visual Analog Scale on Day 35 vs Visual Analog Scale on Day 1, comparing active drug to placebo groups.

Secondary Outcome Measures:
  • Adolescent Pediatric Pain Tool [ Time Frame: At end of each week of treatment ] [ Designated as safety issue: No ]
    The Adolescent Pediatric Pain Tool is a survey that will be administered at baseline and at the end of each of the four weeks of treatment.

  • Skin Temperature and Volume of Affected Limb [ Time Frame: At beginning and end of study ] [ Designated as safety issue: No ]
    The skin temperature and volume of the affected limb will be measured at the beginning and end of the study.

  • Hospital Anxiety and Depression Scale [ Time Frame: Beginning and end of study ] [ Designated as safety issue: No ]
    The Hospital Anxiety and Depression Scale is a survey that will be administered at the beginning and end of the study.

  • Sleep Disturbance Scale for Children [ Time Frame: Beginning and end of the study ] [ Designated as safety issue: No ]
    The Sleep Disturbance Scale for Children is a survey that will be administered at the beginning and end of the study.

  • Sleep pattern and quality [ Time Frame: Daily ] [ Designated as safety issue: No ]
    The patient will sleep with a JawboneUp device, which will measure the sleep pattern and quality.

Estimated Enrollment: 12
