Inclusion Criteria

Inclusion Criteria include:

- Male and female patients, 7 to 16 years of age, inclusive, with malignant and/or
nonmalignant moderate to severe pain requiring or anticipated to require continuous,
around-the-clock, opioid treatment for at least 2 weeks (based on the investigator's
judgment);

- Patients must have written informed consent provided by the parent or legal guardian
and assent provided by the patient, when appropriate;

- Patients on incoming opioids must be taking ≤ 80 mg morphine or equivalent if aged 12
to 16 years or ≤ 40 mg morphine or equivalent if aged 7 to 11 years prior to
initiation with BTDS treatment;

- Patients must be able to understand and complete the age appropriate scale to rate
pain intensity, ie, patients must not have a cognitive developmental delay or any
other condition that would preclude them from completing age appropriate pain scale;

- Patients with malignant and/or nonmalignant medical conditions causing moderate to
severe pain requiring continuous, around-the-clock opioid analgesic therapy such as
cancer, sickle-cell disease (eg, resulting in persistent body pain, persistent limb
pain, avascular necrosis, persistent abdominal pain), persistent orthopedic pain (eg,
spinal injury, spinal disc herniation, persistent limb/stump pain, major trauma),
juvenile rheumatoid arthritis (pain not controlled by therapy treating the underlying
disease), and cystic fibrosis resulting in persistent chest pain;

the protocol, capable of patient evaluation, able to read and understand
questionnaires, willing and able to use a diary, and able to read, understand, and
