Overview
Brief Summary
Breakthrough cancer pain (BTcP) is a rapid onset, high intensity and short duration pain episode, which takes place within stable background pain control. It significantly affects the quality of life of patients with cancer and their ability to function normally. Rapid onset opioids and immediate-release oral opioids (e.g. morphine sulfate, hydromorphone, and oxycodone) are the standard treatment for BTcP. Because of the limited availability, high cost, complicated titration and the high risks of overdosing with rapid-onset opioids, most often the preferred choice of treatment is immediate-release oral opioids. However, this approach might not always offer optimal speed for onset of action and duration to match the rapid nature of an episode of BTcP. In order to seek a potential alternative to immediate-release oral opioids, we are proposing to test the onset of action of PPP001 to rapidly alleviate breakthrough pain in patients with cancer. We will also examine the safety and the efficacy on pain intensity of PPP001 within this population.
Detailed Description
The study is a randomized, open-label crossover comparison study: This will be a 10-week open-label randomized study to evaluate the effect of inhaled PPP001 as compared to morphine sulfate or hydromorphone or oxycodone to improve for the treatment of BTcP. After proper screening and verified inclusion/exclusion criteria, 20 consecutive subjects will be recruited.

Outcomes
Primary Outcomes
Time weighted Sum of Pain Intensity Differences from 0 to 30 minutes (SPID30).
Time Frame: change between 0 min (before starting treatment) and 30 minutes after dosing
SPID30 score after PPP001 administration or immediate-release oral opioids (morphine sulfate or hydromorphone or oxycodone) administration. The SPID30 calculation is based on a 100 mm pain intensity VAS were 0 mm is the minimum and 100 mm the maximum with higher score representing a worse outcome.
Secondary Outcomes
- Pain relief at 5, 10, 15, 30 and 60 minutes(5, 10, 15, 30 and 60 minutes after dosing)
- SPID at 10, 15, and 60 minutes(10, 15, and 60 minutes after dosing)
- Pain intensity difference (PID)(5, 10, 15, 30 and 60 minutes after dosing)
