Comparison of the Pharmacokinetic Properties of Two Tablet Formulations of Macitentan in Healthy Adults
Study Details
Study Description
Brief Summary
A study conducted in healthy adults to investigate if a new macitentan tablet leads to the same fate of macitentan in the body (time of onset, time of presence, amount in the blood) as the marketed macitentan tablet.

Phase 1 |
Detailed Description
The purpose of this study is to establish biocomparison of 2 types of tablets containing macitentan: a pediatric dispersible tablet and the adult film-coated tablet. A single oral dose of each tablet will be given to healthy subjects on 2 different periods separated by a washout phase of 10 to 14 days.
Biocomparison will be based on the comparison of the pharmacokinetic parameters of macitentan with the two types of tablets using specific statistical methods. The pharmacokinetic parameters will be considered equivalent if specific criteria defined in the study protocol are met.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Sequence AB Subjects receive treatment A in Period 1 followed by treatment B in Period 2 with a washout phase of 10 to 14 days between the two treatment periods |
Drug: Treatment A (adult formulation)
Single oral administration of one film-coated tablet containing 10 mg of macitentan as active substance and lactose, magnesium stearate, microcrystalline cellulose, povidone, sodium starch glycolate type A, polysorbate as inactive ingredients.The film coat contains titanium dioxide, talc, xanthan gum, polyvinyl alcohol, and soy lecithin.
Other Names:
Drug: Treatment B (pediatric formulation)
Single oral administration of two dispersible tablets, each containing 5 mg of macitentan as active ingredient and Mannitol delta polymorphic crystals, mannitol, isomalt, isomalt agglomerated, croscarmellose sodium, and magnesium stearate as inactive ingredients.

Outcome Measures
Primary Outcome Measures
- Plasma pharmacokinetic profile [From pre-dose to 216 hours post-dose]
Pharmacokinetic profile will be determined by the following parameters: Cmax (Maximum plasma concentration), tmax (Time to reach Cmax), t1/2 (Terminal half-life), AUC(0-t) (Area under the plasma concentration-time curve from zero to time t of the last measured concentration above the limit of quantification), AUC(0-inf) (Area under the plasma concentration-time curve from zero to infinity)
Other Outcome Measures
- Incidence of adverse events [from baseline to Day 10-13 post-dose]
Number of adverse events and serious adverse events, including abnormal laboratory findings
- ECG abnormalities [from baseline to to Day 10-13 post-dose]
ECG evaluation will be based on the cardiac rhythms measured using a standard 12-lead ECG device
