Summary

This single-site Phase 3 clinical trial is a randomized, double-blind, placebo-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 nausea associated with motion sickness. The study will be conducted aboard an ocean going vessel to obtain data in a real world environment. The study will have three arms: DPI-386 nasal gel, placebo nasal gel, and TDS patch (1.5 mg/72 hours), 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 voyages with the same vessel will be used until the required enrollment is completed. A double dummy design will be used to mask the treatment assignment. All subjects will receive both a patch and nasal gel randomized to one of the following three arms: DPI-386 Nasal Gel + placebo patch, placebo nasal gel + placebo patch, and placebo nasal gel + TDS patch.

Detailed description

The investigational product will be administered using a delivery device comprised of: (a) a vial prefilled with DPI-386 Nasal Gel or placebo nasal gel, and (b) a nasal gel pump attached to the vial during the manufacturing process. Each 0.12 gram of the gel contains 0.2 mg of scopolamine HBr as the active ingredient along with the excipients sodium citrate, citric acid, sodium metabisulfite, glycerin, benzalkonium chloride, polyvinyl alcohol and purified water. The DPI 386 Nasal Gel is formulated to contain 0.2 mg scopolamine HBr per 0.12 g dose, with each dose therefore described as "0.2 mg / 0.12 g". The placebo nasal gel product is the same but does not contain scopolamine HBr. Each vial of DPI 386 Nasal Gel or placebo nasal gel is a multi-dose product, sufficient for three days of dosing (two doses per day). Each pumping action is designed to deliver a single 0.12 g dose. Each vial/delivery device must be primed by the subject prior to first dose delivery for that vial. Each time a new bottle is used, it needs to be initially primed with 5 actuations. The 6th actuation is the first dose and subsequent actuations are doses 2-6 of that bottle. No re-priming is needed at all. Subjects will be trained in priming by research staff, and all priming will be performed under supervision by the research staff. All subjects will self-administer the nasal gel twice daily over the three day treatment period, with no more than two doses every 24 hours, unless a third dose is deemed necessary by the PI or qualified designee, and the two daily doses separated by a minimum of six hours ± 15 minutes
