Trial Outcomes & Findings for Open-Label Study to Evaluate the Effect of Treatment With Fentanyl Buccal Tablets on Pain Anxiety Symptoms When Used for the Management of Breakthrough Pain (NCT NCT00387010)

NCT ID: NCT00387010

Last Updated: 2012-10-22

Results Overview

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

Timeframe: Day 0 (baseline), approximately week 5

Population: Full analysis set

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 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 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.

Population: Safety analysis set

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.
