Brief Summary:
2QG1 is a Phase IIa study aiming to assess the blood pressure lowering effect of 4-week administration of QGC001 oral doses in patients with grade I or II essential hypertension compared to placebo, to assess the safety and tolerability, to obtain preliminary PK information for QGC001 given as multiple oral doses and to determine preliminary PD profile of QGC001 multiple oral doses on plasma and urine hormones, which will be compared to that of placebo.

Primary Outcome Measures :
  1. Efficacy - 24h ABPM [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks (end-of-study visit). ]
    Measurements will include mean 24h systolic and diastolic pressures, and daytime values (measured every 15 min from 07:00 am to 10:00 pm) and night-time values (measured every 20 min from 10:00 pm to 07:00 am). Only ambulatory BP recordings with a minimum of 24 measurements will be considered as successful.


Secondary Outcome Measures :
  1. Efficacy - Self BP measurements at home [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    Additional information will be obtained from self-measurement of BP at home (HBP) with an automatic validated device. To be performed for 7 consecutive days just before the planned visit.

  2. Efficacy - Office BP measurements [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    Office SBP, DBP and HR measured after resting in the semi-recumbent position for at least 5 min. Office SBP, DBP and HR measured after 1 min in a standing position will be recorded at each visit, immediately before the administration of the study drug.

  3. Efficacy - Hormonal measurements [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    The pharmacodynamic neurohormonal effects of QGC001 will be assessed by measurements of plasma active renin, aldosterone, cortisol, adrenocorticotropic hormone (ACTH), apelin and copeptin as well as urine aldosterone, cortisol, creatinine, sodium and potassium using commercially available validated assays.

  4. Pharmacokinetics - Plasma levels of QGC001 [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    Four (4) PK blood samples will be taken. Plasma levels of QGC001 and its metabolite EC33 will be measured using validated LC/MS/MS methods.

  5. Pharmacokinetics - Plasma levels of EC33 [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    Four (4) PK blood samples will be taken. Plasma levels of QGC001 and its metabolite EC33 will be measured using validated LC/MS/MS methods.

  6. Safety - Reported signs and symptoms [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    Patients will report to the center at approximately 08:00 am, without having taken their morning dose, to undergo safety assessments.

  7. Safety - Physical examination [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    The physical examinations will be performed by the investigator or his/her representatives.

  8. Safety - Vital sign measurements [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    For OBP measurements, three consecutive (2 min interval) SBP/DBP measurements will be done with an adapted cuff after resting in the semi-recumbent position for at least 5 min using a validated oscillometric semi-automatic device. In addition, SBP, DBP and HR will be measured after 1 min in a standing position.

  9. Safety - Adverse events [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
  10. Safety - Morisky Medication Adherence Questionnaire [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
  11. Safety - Electrocardiogram [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    The measurements will consist of a 12-lead digital ECG.

  12. Safety - Clinical laboratory tests [ Time Frame: Change from Period 1 to Period 2 up to 16 weeks. ]
    These include blood cells count, fasting glucose, sodium, potassium, chlorides, bicarbonates, creatinine, uric acid, total proteins, total cholesterol, high density lipoprotein (HDL) cholesterol, triglycerides, aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), bilirubin, gamma glutamyl transferase (GammaGT), alkaline phosphatases.
