Status Completed

Clinical Trial Summary

To investigate the efficacy and safety of Nalbuphine ER (NAL ER) tablets in subjects diagnosed with Idiopathic Pulmonary Fibrosis (IPF) and evaluate it's treatment of cough in these patients. This is a two-treatment, 2-period crossover study. Subjects will be randomized in Treatment Period 1 to either NAL ER or matching placebo and evaluated for approximately 21 days. After completion of the first phase, subjects who received NAL ER will crossover to placebo and subjects who received placebo will crossover to NAL ER to complete Treatment Period 2.

Clinical Trial Description

This is a double-blind, randomized, placebo-controlled, 2-treatment, 2-period crossover efficacy and safety study in IPF subjects with NAL ER tablets for the treatment of cough. The study consists of 2 treatment periods of 3 weeks, each followed by a washout period of 2 weeks. Treatment Period 1: During Treatment Period 1, eligible subjects will be randomized (1:1) to one of the following treatment arms: - Arm 1: Active NAL ER followed by crossover Placebo in Treatment Period 2 - Arm 2: Placebo followed by crossover NAL ER in Treatment Period 2 Following 3 weeks of dosing in Treatment Period 1, subjects will complete a 2-week washout period before entering Treatment Period 2. Subjects assigned to Arm 1 will receive placebo and subjects assigned to Arm 2 will receive NAL ER during Treatment Period 2. A final 2-week washout period will occur at the completion of Treatment Period 2. NAL ER Dosing Subjects on NAL ER will have the dose titrated from 27 mg once daily (QD) to 54 mg twice a day (BID) over a 5-day period and then maintained at 54 mg twice a day (BID) for approximately 4 days. Doses will be subsequently escalated and maintained at 108 mg twice a day (BID) over 1 week and then to 162 mg twice a day (BID) over 6 days. ;
