Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this study is to compare the change from baseline in SeSBP between the first-line combination arm and each of the two monotherapy arms at Week 8.;Secondary Objective: • To characterize the safety/tolerability in the two treatment regimens over twelve weeks of active therapy, examining in particular the frequency of treatment discontinuations due to adverse events, the frequencies of hypotension, dizziness, and syncope, the frequency of headaches, and the frequencies of hypokalemia and hyperkalemia. • To compare the change from baseline in SeDBP between the first-line combination arm and each of the two monotherapy arms at Weeks 8 and 12 • To compare the change from baseline in SeSBP between the first-line combination arm and each of the two monotherapy arms at Week 12 • To compare the proportion of subjects with simultaneous SeSBP < 140 mmHg and SeDBP < 90 mmHg between the first-line combination arm and each of the two monotherapy arms at Weeks 8 and 12 • To examine the change from baseline in hs-CRP at Week 12. ;Primary end point(s): * The primary efficacy variable is the change in SeSBP from baseline to Week 8.
