Basic Information

• Recruitment Status: COMPLETED

Brief Summary

This study will be a Phase 1, single-center, open-label, randomized cross-over study to evaluate the PK of a new AP003 device which delivers two sprays of 4 mg naloxone hydrochloride intranasally.

Detailed Description

Based on the intended AP003 product presentation there will be two devices in each carton allowing for administration of a total of 16 mg. This study is designed for subjects to receive naloxone therapy either through the AP003 device or through the currently approved NARCAN® nasal spray (4 mg) device (per label), reference therapy. After administration of the therapy patients will be followed by a 48-hour washout period before treatment crossover. Key study parameters include safety and PK. Safety evaluations will include but not limited to complete and system directed physical examinations (including signs of nasal irritation such as erythema, edema, and erosion), administration of a Brief Smell Identification Test (B-SIT), assessments of vital signs, 12 lead electrocardiogram (ECG), continuous cardiac telemetry monitoring (CCT) , clinical laboratory tests (e.g., hematology, chemistry, urinalysis, pregnancy test), and evaluation of adverse events.
