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
