Primary Outcome Measures :
  1. Mean change in trough sitting diastolic blood pressure (dBP) assessed by conventional BP measurements after 8 weeks of double-blind treatment.

Secondary Outcome Measures :
  1. Mean change in trough sitting sBP and mean BP daytime, nighttime and 24h ABPM after 8 weeks of double-blind treatment.
  2. Responder rate, defined as number (%) of patients achieving BP goals during 8 weeks of double-blind treatment.
  3. Safety and tolerability
