Brief Summary

This multi-site Phase 3 clinical trial is a randomized, double-blind, placebo-controlled and open label active-controlled study to identify the safety and efficacy of a repeated-dose regimen of DPI-386 nasal gel (intranasal scopolamine gel) for the prevention and treatment of motion sickness. The study will be conducted aboard Navy fleet or Marine ships undergoing military operations to obtain data in an operationally relevant real world environment.

Detailed Description

The study will have three arms: DPI-386 nasal gel, placebo nasal gel, and Transderm Scop® (1.5 mg/72 hours; transdermal scopolamine patch [TDS], the current standard of care for the treatment of motion sickness). The study will include 100 subjects per arm, for a total of 300 subjects (n=300). Multiple ships and ships' crews will be used, until the required enrollment is completed. The DPI-386 Nasal Gel and placebo nasal gel arms will be double-blinded, whereas the TDS arm will remain unblinded. Both DPI-386 Nasal Gel and placebo nasal gel will be administered twice daily over the six consecutive Treatment Days. The two daily doses of DPI-386 Nasal Gel or placebo nasal gel will be separated by a minimum of six hours ± 15 minutes, and will occur during the subject's on-duty period. The TDS patch will be administered on Treatment Days 1 and 4.
