Study Details

Study Description

Brief Summary

Part 1, the pharmacokinetic (PK) phase, will expand upon the pilot study conducted at Naval Medical Research Laboratory (NAMRL) and has the goal of determining bioavailability and time to Cmax in a larger representative sample. Part 2, the efficacy phase, is to determine the efficacy of the aqueous spray solution via exposure to a nausea-inducing stimulus.

Condition or Disease Intervention/Treatment Phase
Phase 2/Phase 3

Detailed Description

Part 1: The pharmacokinetic (PK) phase Objective: To determine the bioavailability and amount of scopolamine absorbed after administration of 0.2 mg intranasal scopolamine at regular intervals across 8 hours post- dose.

Hypothesis: Detectable levels of Intranasal scopolamine (INSCOP) will be present in subject plasma within 15 minutes post-dose; mean time to Cmax (maximum plasma concentration) will be less than 1.5 hr.

Part 2: The Efficacy phase Objective: To determine the effectiveness, cognitive performance effects, and medication side-effect profile of 0.2 mg intranasal scopolamine spray as a motion sickness (MS) countermeasure.

Hypothesis: The primary hypothesis is that the INSCOP spray will be more efficacious against MS than placebo, without statistically significant cognitive performance side-effects. Specifically, participants will tolerate significantly more provocative head tilts in the INSCOP condition than in the placebo condition.

Outcome Measures

Primary Outcome Measures

  1. Efficacy: Number of Head Movements During Rotation [40 min]

    During rotation, efficacy is measured by the number of head movements subjects are able to make (12 per minute). While seated yaw-axis rotating, a pre-recorded computerized voice informed subjects to make paced head tilts of 30 ̊ to the right and left at a rate of 0.125 Hz (right, center, left, and back to center over 16 seconds).

Study Results

Participant Flow

Recruitment Details This study enrolled subjects who were active-duty military or reserves on active duty status between the ages of 18 and 59 from the Wright-Patterson Air Force Base located in Dayton, Ohio. The last subjects completed in August 2015.
Pre-assignment Detail For the Pharmacokinetics part, 21 subjects were screened, and 13 completed the pharmacokinetics portion. For Efficacy, 42 subjects were screened, and 23 completed, with one removed from efficacy tabulated results due to noncompliance with study protocol. All subjects randomized into treatment order with cross-over design.
Arm/Group Title PK: Scopolamine Only, Open-label Efficacy: Scopolamine, Then Placebo Efficacy: Placebo, Then Scopolamine
Arm/Group Description Baseline vitals, blood draw, and cognitive testing applied. Subjects then received one dose of 0.2 mg intranasal scopolamine (0.1 mg per nostril). No placebo or efficacy. Blood draws, vitals collection, cognitive testing, and subjective fatigue collected for approximately eight hours post-dose. Subjects received one dose of 0.2 mg intranasal scopolamine (0.1 mg per nostril) for the first of two Efficacy sessions, and then one dose of 0.2 mg placebo intranasal (0.1 mg per nostril) for the second Efficacy session. A minimum of one week separated the two sessions. Each session was identical except for contents of intranasal spray. Baseline vitals, blood draw, and cognitive testing applied prior to dosage. Approximately 40 minutes post-dose, subjects experience mechanical rotation via Coriolis cross-coupling in a stairwise progression until subject reported either full minute of unabated stomach awareness, or the maximum rotation of 40 rpm obtained. Blood draws, vitals collection, cognitive testing and subjective fatigue collected for approximately three hours post-rotation. Subjects received one dose of 0.2 mg intranasal placebo (0.1 mg per nostril) for the first of two Efficacy sessions, and then one dose of 0.2 mg intranasal scopolamine (0.1 mg per nostril) for the second Efficacy session. A minimum of one week separated the two sessions. Each session was identical except for contents of intranasal spray. Baseline vitals, blood draw, and cognitive testing applied prior to dosage. Approximately 40 minutes post-dose, subjects experience mechanical rotation via Coriolis cross-coupling in a stairwise progression until subject reported either full minute of unabated stomach awareness, or the maximum rotation of 40 rpm obtained. Blood draws, vitals collection, cognitive testing and subjective fatigue collected for approximately three hours post-rotation.
