About

This is a phase III, non-inferiority, randomized, double-blind, double-dummy, active-controlled, multicenter study to compare the efficacy and safety of N0877 versus double combination with already established efficacy on systolic blood pressure (SBP) in the sitting position in the medical office in patients with SAH after 8 weeks of treatment.

Full description

This is a phase III, non-inferiority, randomized, double-blind, double-dummy, active-controlled, multicenter study to compare the efficacy and safety of N0877 versus double combination with already established efficacy (olmesartan 40 mg + hydrochlorothiazide 25 mg) in individuals with stage 2 primary arterial hypertension (SBP ≥ 160 ≤ 179 mm Hg or DBP ≥ 100 ≤ 109 mm Hg). This study will be used to support the registration of the new FDC of Eurofarma Laboratórios S.A.

The randomized treatment period aims to demonstrate the non-inferiority of the new combination compared to its comparator on the SBP in patients with SAH in 8 weeks of treatment after randomization.

Throughout the study, the participant must attend to four (04) in-person visits to the research site, being one Screening Visit (VS/V1) throughout the run-in period, one Randomization Visit (VR/V2), one follow-up visit after four (04) weeks (V3), and one Final Visit (VF/V4) after eight (08) weeks of randomized treatment, this being the visit to assess the primary endpoint of the study

Exclusion criteria

1. Pregnant or lactating women.

6. History of hypertensive emergencies in the last 6 months.
7. Moderate to severe cardiovascular (acute myocardial infarction or unstable angina, unstable or life-threatening arrhythmia) and/or cerebrovascular events within the last 6 months or any other disorder that in the opinion of the investigator excludes the participant from the study.
8. Participant who is unwilling to switch from hypertension treatment to study medications.
9. 12-lead electrocardiogram (ECG) with any clinically significant abnormality.
10. Drug or alcohol abuse in the last 2 years.
