Primary Outcome Measures
NameTimeMethod
Change From Baseline in MSSBP at Week 8 Last Observation Carried Forward (LOCF)Baseline, Week 8

Arterial blood pressure (BP) determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSSBP was calculated comparing the Week 8 readings to the readings taken at Baseline. The change from Baseline in MSSBP was analyzed using an analysis of covariance model (ANCOVA) with treatment and country as factors and Baseline MSSBP as a covariate.

Arterial BP determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSSBP was calculated comparing the Week 8 readings to the readings taken at Baseline. The change from Baseline in MSSBP was analyzed using an ANCOVA with treatment and country as factors and Baseline MSSBP as a covariate.

Change From Baseline in Mean 24 Hours, Mean Daytime and Mean Nighttime Systolic Blood Pressure (SBP) at Week 8 LOCF, as Measured by Ambulatory Blood Pressure Measurement (ABPM)Baseline, Week 8

An ABPM measured a participant's blood pressure over a 24-hour period including daytime and nighttime readings, using an automated validated monitoring device from Baseline to Week 8. The 24-hour SBP was calculated by taking the mean of all ambulatory systolic blood pressure readings for the 24-hour period. The change from Baseline in SBP was analyzed using ANCOVA with treatment and country as factors and Baseline MSSBP as a covariate.

Change From Baseline in Mean 24 Hours, Mean Daytime and Mean Nighttime SBP in LCI699 1mg QD Versus LCI699 0.5mg BID Arm at Week 4, as Measured by ABPMBaseline, Week 4

An ABPM measured a participant's blood pressure over a 24-hour period including daytime and nighttime readings using an automated validated monitoring device from Baseline to Week 4. The 24-hour SBP was calculated by taking the mean of all ambulatory systolic blood pressure readings for the 24-hour period. The change from Baseline in SBP was analyzed using an ANCOVA with treatment and country as factors and Baseline MSDBP as a covariate.

Change From Baseline in Mean 24 Hours, Mean Daytime and Mean Nighttime DBP in LCI699 1mg QD Versus LCI699 0.5mg BID Arm at Week 4, as Measured by ABPMBaseline, Week 4

An ABPM measured a participant's blood pressure over a 24-hour period including daytime and nighttime readings using an automated validated monitoring device from Baseline to Week 4. The 24-hour DBP was calculated by taking the mean of all ambulatory diastolic blood pressure readings for the 24-hour period. The change from Baseline in DBP was analyzed using an ANCOVA with treatment and country as factors and Baseline MSDBP as a covariate.

Change From Baseline in MSDBP at Week 8 LOCFBaseline, Week 8

Arterial BP determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSDBP was calculated comparing the Week 8 readings to the readings taken at Baseline. The change from Baseline in MSDBP was analyzed using an ANCOVA with treatment and country as factors and Baseline MSDBP as a covariate.

Percentage of Participants With a MSDBP Response and MSDBP Control at Week 8, as Measured by OBPWeek 8

MSDBP response was defined as the percentage of participants with a MSDBP \<90 mmHg or a \>=10 mmHg reduction from baseline. MSDBP control was defined as the percentage of participants with a MSDBP \<90 mmHg for non-diabetic participants and \<80mHg for diabetic participants.

Percentage of Participants With a MSSBP Response and MSSBP Control at Week 8, as Measured by Office Blood Pressure (OBP)Week 8

MSSBP response was defined as the percentage of participants with a MSSBP \<140 mmHg or a \>=20 mmHg reduction from baseline reduction from baseline. MSSBP control was defined as the percentage of participants with a MSSBP \<140 mmHg for non-diabetic participants and \<130mHg for diabetic participants.

Dose/Exposure BP Response Relationship of LCI699, as Measured by Change From Baseline in MSDBP at Week 8Baseline, Week 8

Arterial BP determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSDBP was calculated comparing the Week 8 readings to the readings taken at Baseline.

Change From Baseline in Mean 24 Hours, Mean Daytime and Mean Nighttime Diastolic Blood Pressure (DBP) at Week 8 LOCF, as Measured by ABPMBaseline, Week 8

An ABPM measured a participant's blood pressure over a 24-hour period including daytime and nighttime readings, using an automated validated monitoring device from Baseline to Week 8. The 24-hour DBP was calculated by taking the mean of all ambulatory diastolic blood pressure readings for the 24-hour period. The change from Baseline in DBP was analyzed using an ANCOVA with treatment and country as factors and Baseline MSDBP as a covariate.

Number of Participants With Adverse Event (AEs), Serious Adverse Events (SAEs), Hyperkalemia, and HyponatremiaAEs, Hyperkalemia, and Hyponatremia: From start of the study drug treatment up to 10 weeks; SAE: From signing of the informed consent up to 10 weeks

An AE was an adverse medical event which occurs in a participant of the study and which is not necessarily in a causal relationship with the treatment the participant receives. SAEs were AEs leading to death, are life-threatening, require hospitalizations or prolongation of hospitalizations, represent an innate malformation or a congenital abnormality. Hyperkalemia was defined as potassium level \>5.5 millimoles per liter (mmol/L). It is the medical term that describes a potassium level that's higher than normal. Hyponatremia was defined as sodium level \<135 mmol/L. It is the medical term that describes a sodium level that's lesser than normal.

Number of Participants With Cortisol Levels Below 500 Nmol/L at 1 Hour After Adrenocorticotropic Hormone (ACTH) Injection at Week 81-hour post-dose at Week 8

Serum cortisol concentrations at 1 hour after injection were measured to assess the maximum stimulated cortisol level achieved. Potential adrenal suppression was indicated if the serum cortisol concentration was \<500 nanomoles per liter (nmol/L) at 1 hour after the injection.

Percent Change From Baseline in Renin-Angiotensin-Aldosterone-System (RAAS) Biomarker: Plasma Aldosterone (PA) in LCI699 Compared to Eplerenone 50 mg at Week 8 LOCFBaseline, Week 8

Percent change from Baseline was analyzed by ANCOVA model using PA values measured at Baseline and Week 8 LOCF, with treatment and country as factors and Baseline value as the covariate. Negative percent change from Baseline shows improvement.

Percent Change From Baseline in RAAS Biomarker: Plasma Renin Activity (PRA) in LCI699 Compared to Eplerenone 50mg at Week 8 LOCFBaseline, Week 8

Percent change from Baseline was analyzed by ANCOVA model using plasma renin values measured at Baseline and Week 8 LOCF, with treatment and country as factors and Baseline value as the covariate. Negative percent change from Baseline shows improvement.

Percent Change From Baseline in RAAS Biomarker: Active Renin (ARC) in LCI699 Compared to Eplerenone 50mg at Week 8 LOCFBaseline, Week 8

Percent change from Baseline was analyzed by ANCOVA model using active renin values measured at Baseline and Week 8 LOCF, with treatment and country as factors and Baseline value as the covariate. Negative percent change from Baseline shows improvement.

Percent Change From Baseline in RAAS Biomarker: Ratio of PA to PRA in LCI699 Compared to Eplerenone 50mg at Week 8 LOCFBaseline, Week 8

Percent change from Baseline was analyzed by ANCOVA model using percent ratio of PA to PRA values measured at Baseline and Week 8 LOCF, with treatment and country as factors and Baseline value as the covariate. Negative percent change from Baseline shows improvement.
