Study Description

Brief Summary:

The aim of this Phase 1 trial is to study a potential drug-drug interaction between macitentan and rosuvastatin, a model substrate of various transporter proteins (e.g. in the gut).

Condition or disease	Intervention/treatment	Phase
Healthy Subjects	Drug: Rosuvastatin; Drug: Macitentan	Phase 1

Detailed Description:

Rosuvastatin is a substrate of various transporter proteins including breast cancer resistance protein (BCRP) and organic anion-transporting polypeptides (OATP). It is unknown to which extent macitentan has an effect, if any, on BCRP transporters, especially intestinal BCRP. The primary purpose of this Phase 1 study is to investigate the effect of macitentan on the pharmacokinetics of rosuvastatin, a model BCRP substrate.

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 20 participants
• Allocation: N/A
• Intervention Model: Single Group Assignment
• Intervention Model Description: All subjects will receive rosuvastatin alone (treatment A) or with macitentan at steady state (treatment B). A fixed sequence design was selected to avoid a lengthy washout period and unnecessary prolongation of subjects' participation in the study.
• Masking: None (Open Label)
• Primary Purpose: Other
• Official Title: A Single-center, Open-label, One-sequence, Two-treatment Study to Investigate the Effect of Macitentan at Steady State on the Pharmacokinetics of Rosuvastatin in Healthy Male Subjects.
• Actual Study Start Date: November 3, 2017
• Actual Primary Completion Date: December 4, 2017
• Actual Study Completion Date: December 4, 2017

Arms and Interventions

Arm

Intervention/treatment

Experimental: Sequence AB; Subjects participate in two study periods: During the first period (treatment A), they receive a single oral dose of rosuvastatin on Day 1. During the second period (treatment B), they receive a single oral loading dose of macitentan on Day 5 and oral doses of macitentan from Day 6 to Day 16 (i.e., 11 doses). Subjects receive a single oral dose of 10 mg rosuvastatin concomitantly with macitentan in the morning of Day 10.

Drug: Rosuvastatin; Single oral dose of 10 mg rosuvastatin (film-coated tablet) on Day 1 and Day 10; Drug: Macitentan; Single oral dose of 30 mg macitentan (film-coated tablet) on Day 5 and 10 mg macitentan administered orally from Day 6 to Day 16; Other Name: ACT-064992

Outcome Measures

Primary Outcome Measures :

1. AUC(0-inf) of rosuvastatin following administration of rosuvastatin alone (treatment A) and in combination with macitentan (treatment B) [ Time Frame: From Day1 to Day17 (treatment A: from Day1-Day5 and treatment B: from Day10-Day17) ]
   AUC(0-inf) is the area under the plasma concentration-time curves of rosuvastatin, calculated from time zero to the extrapolated infinite time
2. Cmax of rosuvastatin following administration of rosuvastatin alone (treatment A) and in combination with macitentan (treatment B) [ Time Frame: From Day1 to Day17 (treatment A: from Day1-Day5 and treatment B: from Day10-Day17) ]
   Cmax is the maximum observed plasma concentration and is directly derived from the individual plasma concentration time curves of rosuvastatin

Secondary Outcome Measures :

1. tmax of rosuvastatin following administration of rosuvastatin alone (treatment A) and in combination with macitentan (treatment B) [ Time Frame: From Day1 to Day17 (treatment A: from Day1-Day5 and treatment B: from Day10-Day17) ]
   The time to reach maximum plasma concentration (tmax) of rosuvastatin
2. t½ of rosuvastatin following administration of rosuvastatin alone (treatment A) and in combination with macitentan (treatment B) [ Time Frame: From Day1 to Day17 (treatment A: from Day1-Day5 and treatment B: from Day10-Day17) ]
   t½ is the terminal half-life of rosuvastatin and corresponds to the period of time required for the concentration levels of rosuvastatin to be reduced by one-half
3. AUC(0-t) of rosuvastatin following administration of rosuvastatin alone (treatment A) and in combination with macitentan (treatment B) [ Time Frame: From Day1 to Day17 (treatment A: from Day1-Day5 and treatment B: from Day10-Day17) ]
   AUC(0-t) is the area under the plasma concentration-time curve from time zero to time t of the last measured concentration above the limit of quantification of rosuvastatin
4. Trough plasma concentrations of macitentan and its metabolite ACT-132577 [ Time Frame: From Day5 to Day17 ]
   Trough concentrations of macitentan and ACT-132577 are measured before oral administration of macitentan
5. Change from baseline in supine blood pressure [ Time Frame: From Day1 to end-of-study visit (Day 26-28) ]
   Change from baseline to each time point of measurement during study period
6. Change from baseline in pulse rate [ Time Frame: From Day1 to end-of-study visit (Day 26-28) ]
   Change from baseline to each time point of measurement during study period
7. Change from baseline in heart rate (HR) [ Time Frame: From Day1 to end-of-study visit (Day 26-28) ]
   Change from baseline to each time point of measurement during study period
8. Change from baseline in ECG variables [ Time Frame: From Day1 to end-of-study visit (Day 26-28) ]
   Change from baseline to each time point of measurement during study period in ECG variables: PR, QRS, QT, RR, and QT corrected for Bazett's and Fridericia's formulae (QTcB and QTcF, respectively)
9. Change from baseline to end-of-study (EOS) in body weight [ Time Frame: From Day1 to end-of-study visit (Day 26-28) ]
   Change in body weight measured in kg during study period
10. Change from baseline in clinical laboratory tests [ Time Frame: From Day1 to end-of-study visit (Day 26-28) ]
    Change from baseline to each time point of measurement during study period for clinical laboratory tests (hematology, clinical chemistry, serology)
11. Incidence rate of treatment-emergent treatment-emergent adverse events (AEs) and serious adverse events (SAEs) [ Time Frame: From Day1 to follow-up period (Day46-48) ]
    Incidence rates of treatment-emergent AEs including abnormalities in ECG variables during each treatment as well as AEs leading to the discontinuation of study treatment. A treatment-emergent AE is any AE temporally associated with the use of a study treatment, whether or not considered related to the study treatment.
