Positive phase III efficacy clinical trial for Fentanyl sublingual spray .....

INSYS Therapeutics, Inc. announced positive results from the pivotal phase III efficacy  trial for patients utilizing the Fentanyl Sublingual Spray (SL Spray) technology to treat breakthrough cancer pain.  The company claims that all primary and secondary endpoints were achieved in the study, and the drug is the first product to ever show statistically significant pain relief when measuring the summary of pain intensity difference at five minutes (SPID(5)) in a phase III breakthrough cancer pain trial using Fentanyl.

Dr. Richard Rauck, a principal investigator in the Phase III study observed,  the sublingual spray demonstrated very rapid, effective pain relief. Patients began to experience meaningful pain relief within five minutes. This observation was supported by the clinical research findings.  As claimed by the researchers, to date, no other transmucosal Fentanyl  (see the general structure) product has produced pain relief this quickly. This  finding is supported with continued pain relief at all subsequent time intervals. 

Hope this easy-to-use oral spray that can produce effective, potent and very rapid pain relief will be a tremendous advantage for the  patients who experience moderate to severe cancer breakthrough pain.....
