Comparative bioavailability study of film-coated tablet and granuleformulations of RG1662

Status:

Completed

Protocol number:

WP28978

Sponsor:

Hoffmann-La Roche

Company division:

Pharmaceutical

Product name:

RG1662

Official Scientific Title:

A Randomized, Open-Label, Four Period, Four-Treatment Crossover Study toInvestigate the Comparative Bioavailability of Film-Coated Tablet and GranuleFormulations of RG1662 Under Fed and Fasted Conditions in Healthy Volunteers

Brief summary:

This study will compare the pharmacokinetic performance of film-coatedtablet and granule formulations of RG1662 under fed and fasted conditions inhealthy volunteers. A randomized, four-period, four-treatment crossover designis used. In each period, each volunteer will receive a single oral dose of thetablet or granule formulation either with or without food. Target sample sizeis 18.

Study phase:

I

Study type:

Interventional; Other; Randomized; Open label; Crossover; Bio-availabilitystudy

Conditions:

·         Healthy Volunteer

Primary outcome:

1.    Tablet Fed (reference): RG1662 plasmaexposure, area under the concentration-time curve Time frame: Up to 9 weeks

2.    Tablet Fasted (reference): RG1662 plasmaexposure, area under the concentration-time curve Time frame: Up to 9 weeks

3.    Granules Fed (test): RG1662 plasmaexposure, area under the concentration-time curve Time frame: Up to 9 weeks

4.    Granules Fasted (test): RG1662 plasmaexposure, area under the concentration-time curve Time frame: Up to 9 weeks

Key secondary outcomes:

1.    Tablet formulation: RG1662 plasma exposureratio between fed (test) and fasted (reference) conditions, estimated from areaunder the concentration-time curve measurements Time frame: Up to 9 weeks

2.    Granule formulation: RG1662 plasmaexposure ratio between fed (test) and fasted (reference) conditions, estimatedfrom area under the concentration-time curve measurements Time frame: Up to 9weeks

3.    Palatability of the granule formulation,as assessed by questionnaire Time frame: Day 1, Day 3 in granule administrationperiods
