According to the
The INSYS study was a single-dose, open-label, randomized, four-treatment, four-way crossover study. Twenty-four healthy volunteer subjects received one dose each of 8 mg naloxone nasal spray (Formulation I and Formulation II), one dose of 2 mg Naloxone HCl IV Injection (1 mg/mL), and one dose of Naloxone HCl IM Injection (0.4 mg/mL).
The results from the study, per the graph below, demonstrate that the mean unconjugated naloxone plasma concentrations after administration of the two test nasal formulations:
1) reached appreciably higher levels than those observed after the administration of the IM dose at all timepoints beginning at two minutes; and
2) maintained high levels above the Cmax of 0.4 mg IM for two hours.
Unconjugated naloxone exposure generated from the two test nasal formulations were from 9.6- to 27-fold higher compared to Naloxone 0.4 mg IM.
The results of this study are consistent with the prior study conducted by INSYS (INS012-17-108) that compared the company’s two proprietary nasal formulations with 0.4 mg of Naloxone Intramuscular
“Due to the introduction of synthetic opioids, a more potent, longer-lasting naloxone is required to address an unmet need in today’s opioid epidemic,” said Ahmed Elkashef, M.D., vice president of clinical development at INSYS. “The PK results from this study suggest that our naloxone nasal spray formulation may hold promise to address this unmet need. Based on these results, we look forward to working with the FDA to bring a new treatment to people on the front lines of the opioid crisis.”
Upon receiving the results from the nonclinical juvenile toxicity study, the company plans to file the NDA at the end of the first quarter of 2019.
