Intervention / Treatment
Detailed Description
Stage I: dose-response relationship and safety assessment of inhaled fentanyl aerosol in patients with breakthrough cancer pain. placebo-controlled, cross-over, double-blind randomized design is applied in this stage.
Patients meeting the inclusion/exclusion criteria will be treated with inhaled fentanyl aerosol (4 of 6 episodes BTcp) or placebo (2of 6 episodes BTcp).Subjects will inhale fentanyl aerosol or placebo for each episode of BTcp with a starting dose of 25 µg every 4 minutes until adequate pain alleviation. The maximum doses are 6×25 µg.
Stage II: The dosage regimen (number of puffs) will be depended on the data from Stage I. Subjects will inhale fentanyl aerosol not in the episode of breakthrough cancer pain with a starting dose of 25 µg every 4 minutes.

Experimental: Inhaled fentanyl aerosol
Participants in the stage I were randomized to 6 BTP episodes, in which 4 BTP episodes were treated with inhale fentanyl aerosol (with a starting dose of 25 µg every 4 minutes until adequate pain alleviation.
The maximum doses are 6×25 µg) and 2 BTP episodes with placebo(0 µg every 4 minutes until adequate pain alleviation.
The maximum doses are 6×0µg) in a random sequence.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
SPID30
Time Frame: During the stage I, at each episode of breakthrough pain, 30 minutes after first dose of study drug.
|
Weighted sum of pain intensity difference at post dose 30 minutes.Pain intensity at each breakthrough pain (BTP) episode at 0 ,4,8,12,16,20 and 30 minutes after first dose using the 11-point Numerical Rating Scale (NRS) on a scale from 0 to 10, where 0 represents the absence of pain and 10 is "worst possible pain".
PID30 is calculated as the difference in pain intensity from time 0 to 30 minutes.
A positive value is a decrease (improvement) of the pain.SPID30=PID4*4+PID8*4+PID12*4+PID16*4+PID20*4+PID30*10

Overall responder rate is defined as the proportion of breakthrough pain (BTP) episodes with a positive response to treatment.
The following definitions of a positive response were analyzed: greater than or equal to 3 point reduction in PI from time 0. Pain intensity was assessed using the 11-point Numerical Rating Scale (NRS) on a scale from 0 to 10, where 0 represents the absence of pain and 10 is "worst possible pain".
