Maximum Tolerated Dose (MTD) of LCI699 With Respect to Effect on the Adrenocorticotropic Hormone (ACTH)-Stimulated Cortisol Response Following ACTH Stimulation in Hypertensive Participants

As per the protocol, MTD is the dose at which 4 participants exhibited ACTH-stimulated cortisol results <400 nanomoles per liter (nmol/L). The change in the distribution across the treatments were analyzed using 1- way analysis of variance (ANOVA) for continuous variables.

LCI699 Exposure-response Relationship on Cortisol Levels Following ACTH Stimulation in Hypertensive Participants

Exposure-response relationship was assessed using ACTH stimulation test. Tests were done 2 hours after study drug administration (i.e., at peak LCI699 concentrations). An increase in cortisol greater than >500 nmol at 60 minutes after ACTH administration was expected.

Percentage of Participants With a Mean Sitting Systolic Blood Pressure (MSSBP) Response and MSSBP Control at Week 6 Last Observation Carried Forward (LOCF), as Measured by Office Blood Pressure (OBP)

Automated arterial BP determinations was made with an automated BP device (such as the Omron BP monitor) in accordance with the Guidelines for management of hypertension: report of the 4th working party of the British Hypertension Society, 2004-BHS IV. Sitting and standing blood pressure (BP) and heart rate (HR) measurements were performed. MSSBP response was defined as the percentage of participants with a MSSBP <140 mmHg or a >=20 mmHg 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.
