Study of Single and Multiple Doses of Inhaled AeroLEF (Liposome-Encapsulated Fentanyl)in Healthy Subjects - Full Text View

Purpose

This study was designed to assess single-dose and multiple-dose PK and safety parameters utilizing a dosage of 3 mL (500 µg/mL)AeroLEF delivered via nebulization with the AeroEclipse BAN device. The study was conducted in opioid naïve subjects who were not blocked with naloxone or other opioid receptor antagonists.

Active Comparator: Treatment Group A Subjects received an i.v. dose of fentanyl (200 µg)	Drug: i.v. fentanyl single dose, 200 ug Other Name: fetanyl citrate injection
Experimental: Treatment Group B Subjects received a single dose of 3 mL AeroLEF (500 µg/1 mL)	Drug: 3 mL AeroLEF (500 µg/1 mL) A single dose of 3mL (500 µg/1 mL) of AeroLEF (Aerosolized Free and Liposome-Encapsulated Fentanyl) Other Name: Aerosolized Free and Liposome-Encapsulated Fentanyl
Experimental: Treatment Group C Subjects received multiple doses of 3 mL AeroLEF (500 µg/1 mL) every 12 hours for a total of five doses over a 3 days	Drug: 3 mL AeroLEF (500 µg/1 mL) A multiple doses of 3mL (500 µg/1 mL)of AeroLEF (Aerosolized Free and Liposome-Encapsulated Fentanyl)every 12 hours for a total of five doses over a 3 days Other Name: Aerosolized Free and Liposome-Encapsulated Fentanyl

Detailed Description:

Period I: Subjects received an i.v.dose of fentanyl (200 µg) (Treatment A).

Period II: Subjects were randomly assigned to receive either a single-dose (Treatment B) or multi-dose (Treatment C) of AeroLEF.

In the multi-dose Treatment C group, subjects received a dose of 3 mL AeroLEF every 12 hours for a total of five doses over a 3 days with a 4 week washout period before crossing over to Period III.

Period III: Subjects from Period II participated in the crossover study and receive either a multi-dose (Treatment C, 5 doses at 12 hour intervals) or a single dose (Treatment B). Subjects in Treatment B or Treatment C were instructed to continue inhalation of AeroLEF for approximately one (1) minute beyond the point of nebulizer sputter to ensure that all aerosolized medication was delivered.
