Brief Summary:
The primary purpose of this study is to evaluate the safety and tolerability of ascending multiple doses of ACT-709478 in healthy male and female subjects

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Other
Official Title: A Single-center, Double-blind, Parallel-group, Randomized, Placebo-controlled, Multiple-ascending Oral Dose Study to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of ACT-709478 in Healthy Subjects
Actual Study Start Date : July 24, 2017
Actual Primary Completion Date : November 15, 2018
Actual Study Completion Date : November 15, 2018

Arm Intervention/treatment
Experimental: ACT-709478

Up to 30 healthy male and female subjects (40 subjects if the optional fourth dose level is conducted) will receive multiple doses of ACT-709478 at the planned dose levels of 30, 100, and 200 mg.

Each dose level will be investigated in a new cohort of 10 healthy male and female subjects (4 male subjects on active drug and 1 on placebo, 4 female subjects on active drug and 1 on placebo) undergoing one treatment period with a once daily dosing scheme.

Drug: ACT-709478
Hard gelatine capsules for oral administration

Placebo Comparator: Placebo
Matched placebo administered accordingly
Drug: Placebo
Placebo capsules matching ACT-709478 capsules




Primary Outcome Measures :
  1. Incidence of treatment-emergent adverse events [ Time Frame: up to Day 23 ]
    The percentage of subjects with treatment-emergent adverse events will be reported

  2. Changes from baseline in vital signs [ Time Frame: up to Day 23 ]
    Vital signs include diastolic and systolic blood pressure and pulse rate

  3. Incidence of any clinical relevant findings in ECG variables [ Time Frame: up to Day 23 ]
    The number of subjects with any treatment-emergent electrocardiogram (ECG) abnormalities will be reported


Secondary Outcome Measures :
  1. Maximum plasma concentration (Cmax) of ACT-709478 [ Time Frame: up to Day 23 ]
    Cmax is derived from the observed plasma concentration-time curves

  2. Time to reach Cmax (tmax) of ACT-709478 [ Time Frame: up to Day 23 ]
    tmax is directly derived from the observed plasma concentrations

  3. Terminal half-life (t1/2) of ACT-709478 [ Time Frame: up to Day 23 ]
    t1/2 is calculated from the terminal rate constant obtained from the plasma concentrations-time curves

  4. Area under the plasma concentration-time curve AUC(tau) of ACT-709478 [ Time Frame: up to Day 23 ]
    AUCtau is defined as the area under the plasma concentration-time curve during one dosing interval
