The patient reports an average pain intensity score, over the prior 24 hours, of 6 or less (0=no pain through 10=worst pain) for the chronic pain.
The patient experiences, on average, 1 to 4 BTP episodes per day while taking around-the-clock (ATC) opioid therapy, and on average, the duration of each breakthrough pain (BTP) episode is less than 3 hours.
The patient currently uses opioid therapy for alleviation of BTP episodes occurring at the location of the chronic pain, and achieves at least partial relief.
The patient must be willing and able to successfully self-administer the study drug, comply with study restrictions, and return to the clinic for scheduled study visits and a follow-up evaluation as specified in this protocol.

Exclusion Criteria

The patient's primary painful condition is headache, including migraine.
The patient is expected to have surgery during the study, and it is anticipated that the surgery will alleviate the patient's pain.
The patient has had therapy before study drug treatment that, in the opinion of the investigator, could alter pain or response to pain medication.

Arm && Interventions

Group	Intervention	Description
fentanyl buccal tablets	Fentanyl Buccal Tablets	Successful dose strength for each participant was determined during a titration period of no more than 10 days. Participants used the successful dose of 100, 200, 400, 600, or 800 mcg during the four week open-label treatment period.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in the Pain Anxiety Symptoms Scale (PASS) Total Score at Approximately Week 5	Day 0 (baseline), approximately week 5	The change from baseline to approximately week 5 in the PASS total score. PASS asks participants to indicate how often they engage in each of the 40 thoughts or activities that represent anxiety symptoms on a scale of 0=never to 5=always. The total score has a range of 0-200.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in the Pain Anxiety Symptoms Scale (PASS) Subscale Scores at Approximately Week 5	Day 0 (baseline), approximately week 5	The change from baseline to approximately week 5 in the PASS subscale scores. PASS asks participants to indicate how often they engage in each of the 40 thoughts or activities that represent anxiety symptoms on a scale of 0=never to 5=always. Those 40 questions are organized into four subscales: fear, cognitive anxiety, somatic anxiety, and escape/avoidance. Each subscale score is obtained by summing the answers to the ten items in the subscore resulting in a range of 0-50.
Change From Baseline in the Beck Depression Inventory at Approximately Week 5	Day 0 (baseline), approximately week 5	Change from baseline to endpoint (week 4 of Treatment period or last post baseline visit) in the Beck Depression Inventory (BDI). The BDI is a self-reporting instrument that asks 21 questions regarding how the participant felt in the past few days. Answers are in sentence form, and offer a scale where the first answer (worth 0 points) indicates no depression and the fourth answer (worth 3 points) indicates significant depression. Totals (0-63) are grouped so that totals of 1-10 are interpreted as 'These ups and downs are considered normal' and scores \>40 indicate extreme depression.
Change From Baseline in the West Haven-Yale Multidimensional Pain Inventory Subscales at Approximately Week 5	Day 0 (baseline), approximately week 5	Change from baseline to endpoint (week 4 of Treatment period or last post baseline visit) in the Multidimensional Pain Inventory Subscales. Answers to questions in the MPI are captured on a 7-point scale, with 0=most positive answer and 6= least positive answer. Twenty questions focus on pain, fourteen on a significant other's response when participant is in pain, and eighteen questions about daily activities. There are a total of 13 subscales with variable ranges. Subscales and corresponding ranges are listed in the results table. The General Activity category combines the Household Chores, Outdoor Work, Activities Away from Home, and Social Activities categories.

Summary of Participants' Successful Dosing Levels of Fentanyl Buccal Tablets to Control Episodes of Breakthrough Pain (BTP)	up to 10 days	During the dose titration period, participants self-administered FBT, starting at 100, 200 or 400 mcg (depending on analgesic used pre-study) and titrated to 600 and 800 mcg if needed. For each breakthrough pain (BTP) episode, participants took a dose, and did not take further study drug if adequate pain relief was achieved. If pain was not controlled within 30 minutes, the same dose level was repeated. If pain relief was inadequate 30 minutes after the second dose, usual rescue medication was taken for that BTP episode. Doses were adjusted until pain relief was adequate and side effects were tolerated. This outcome summarizes the successful dose levels identified during the titration period.
