Insys Therapeutics announced that the Food and Drug Administration (FDA) has accepted for filing the New Drug Application (NDA) for its novel buprenorphine sublingual spray for the management of moderate-to-severe acute pain

The NDA submission was supported by data from a study that met its primary efficacy endpoint in addition to several pharmacokinetic studies. Recently, the Company finished a 7-day safety and tolerability study among 100 patients for which the data will be submitted to the FDA in early 2018.

Compared to other commonly used opioids, buprenorphine offers a ceiling effect for respiratory depression and less abuse potential, less cognitive impairment, and less constipation.
