TRIAL DRUG:~GMRx2: Single pill combinations of telmisartan/amlodipine/indapamide Dose version 2: telmisartan 20mg/amlodipine 2.5mg/indapamide 1.25mg Dose version 3: telmisartan 40mg/amlodipine 5 mg/indapamide 2.5mg INDICATION: Hypertension TRIAL DESIGN: International, multicenter, randomized, double-blind, active controlled, parallel-group.~OBJECTIVES: To investigate the efficacy and safety of GMRx2 compared to dual combinations~INTERVENTION:~Single-Blind Active Run-In Period. Enrolled participants will be asked to discontinue their current BP-lowering drug(s) and undergo a single-blind active run-in period for 4 weeks with GMRx2 dose version 2. Participants will be advised to take the capsule once daily in the morning at the same time (± 2 hours) before home BP measurement is performed.~Double-Blind Treatment Period. Participants still eligible after the run-in period will be allocated in a double-blind fashion to one of the following 4 randomized groups: GMRx2 dose version 2, or telmisartan20mg+amlodipine2.5mg, or telmisartan 20mg+indapamide 1.25mg, or amlodipine2.5mg+indapamide 1.25mg. At week 6 all doses will be doubled.
Recent hypertension guidelines recommend combination therapy as initial treatment for many or most patients. Several trials suggest triple low-dose combination therapy may be highly effective in terms of achieving blood pressure control without increasing adverse effects. This trial is designed to investigate the efficacy and safety of GMRx2 in participants with high blood pressure compared to dual combinations.
