Bioequivalence and Food Effect Bioavailability Study of Lumacaftor Film-Coated Tablets

A Single-Dose, Bioequivalence and Food Effect Bioavailability Study in Healthy Volunteers Comparing the Commercial Lumacaftor 200 mg / Ivacaftor 125 mg Combination Film-Coated Tablet (Orkambi®) to the Lumacaftor 200 mg Film-Coated Tablet Formulation, and the Lumacaftor 200 mg Film-Coated Tablet Formulation in the Fasted to Fed State.

The objective of this study is to assess bioequivalence of lumacaftor from Lumacaftor 200 mg Film-Coated Tablet Formulation (Qanatpharma) versus the reference commercial product, Lumacaftor 200 mg /Ivacaftor 125 mg Combination Film-Coated Tablet (Orkambi®) in the fed state, and food-effect bioavailability of Lumacaftor 200 mg Film-Coated Tablet Formulation (Qanatpharma) in the fasted and fed state in healthy, non-smoking, male and non-pregnant female volunteers, 18 to 55 years of age, inclusive.

Study Overview

• Status: Completed
• Conditions: Healthy Volunteer
• Intervention / Treatment: Drug: Lumacaftor 200 mg Film-Coated Tablet Formulation; Drug: Lumacaftor 200 mg/Ivacaftor 125 mg Film-Coated Tablet

Detailed Description

This single-dose, randomized, open-label, three-way crossover, three-period, three-sequence, three-treatment, single-centre, bioequivalence and food-effect study will compare lumacaftor from Lumacaftor 200 mg Film-Coated Tablet test formulation and the commercial product, Lumacaftor 200 mg/Ivacaftor 125 mg Combination Film-Coated Tablet (Orkambi®) under fed conditions, and food-effect bioavailability study of Lumacaftor 200 mg Film-Coated Tablet test formulation from fasted to fed state.

The products will be studied using a crossover design with 39 healthy, non-smoking male and non-pregnant female volunteers being administered an oral dose of 1 x (2 x lumacaftor 200 mg) under fasted and fed conditions and 1 x (2 x lumacaftor 200 mg/ ivacaftor 125 mg) under fed conditions. There will be at least a 14-day washout period between the study periods to avoid carry-over effects of the preceding treatments.

This study is being conducted to support development of a lumacaftor mono-substance treatment for improving cerebral blood flow.
