Inclusion Criteria
  • Signed informed consent
  • Body mass index (BMI) of 18.0 to 31.0 kg/m2 (inclusive) at screening
  • Systolic blood pressure (SBP) 100-145 mmHg, diastolic blood pressure (DBP) 50-90 mmHg, and pulse rate 45-90 beats per minute (inclusive) at screening
  • Healthy on the basis of physical examination, electrocardiogram and laboratory tests

GroupInterventionDescription
AC-076 sc administration - single ascending doseAC-076 for s.c. administrationOn Day 1, 48 subjects will receive AC-076 at different single dose levels in a sequential manner and in a maximum of 6 dose levels, starting from 1 mg. Subjects will be followed by an observation period of 48 h. Each dose level will be investigated in a new group of 8 healthy male subjects (6 on active drug and 2 on placebo)
PlaceboPlaceboFor each AC-076 dose level tested, 2 healthy male subjects will receive matching placebo in the same condition
Primary Outcome Measures
NameTimeMethod
Number of participants with adverse events (AEs)From study treatment administration up to day 3

Treatment-emergent AEs and treatment-emergent serious AEs

Changes from baseline in electrocardiogram (ECG) variablesFrom study treatment administration up to day 3

ECG variables are to be recorded at rest using a standard 12-lead ECG

Changes from baseline in supine blood pressureFrom study treatment administration up to day 3

Supine blood pressure (mmHg)

Changes from baseline in pulse rateFrom study treatment administration up to day 3

Pulse rate (bpm)

Secondary Outcome Measures
NameTimeMethod
Maximum plasma concentration (Cmax) of AC-076From baseline up to day 3

Cmax of AC-076 will be derived by non-compartmental analysis of the plasma concentration-time profile

time to reach Cmax (tmax)From baseline up to day 3

tmax of AC-076 will be derived by non-compartmental analysis of the plasma concentration-time profile

Measurement of inhibition of platelet aggregation (IPA) using anticoagulant assaysFrom baseline up to day 3

Maximum (MPA) and final (FPA) platelet aggregation using light transmission aggregometry (LTA) assay.

% inhibition of platelet aggregation (IPA), MPA and FPA.

P2Y12 reaction units (PRU) using the VerifyNow P2Y12 assay.

* IPA PRU

Area under the plasma concentration-time curves from time 0 to inf [AUC(0-inf)]From baseline up to day 3

AUC(0-inf) of AC-076 will be derived by non-compartmental analysis of the plasma concentration-time profile

Area under the plasma concentration-time curves during a dosing interval [AUC(0-t)] ofFrom baseline up to day 3

AUC(0-t) of AC-076 will be derived by non-compartmental analysis of the plasma concentration-time profile

terminal half-life (t1/2)From baseline up to day 3

t1/2 of AC-076 will be derived by non-compartmental analysis of the plasma concentration-time profile
