To Assess Allisartan Isoproxil/Sustained-Release Indapamide in Patients With Essential Hypertension Uncontrolled With Allisartan Isoproxil

Phase 3
Completed
Conditions
Essential Hypertension
Interventions
Registration Number
NCT06500689
Lead Sponsor
Shenzhen Salubris Pharmaceuticals Co., Ltd.
Brief Summary

The main objective of the study will be to assess the efficacy and safety of Allisartan Isoproxil/sustained-release indapamide (240 mg/1.5 mg) in patients with mild to moderate essential hypertension uncontrolled after 4-week treatment with Allisartan Isoproxil (240 mg).

Detailed Description

Allisartan isoproxil is a novel angiotensin receptor blocke available in China for over ten years and has the same active compound EXP3174 with losartan, while sustained-release indapamide is a long-standing thiazide-type diuretic. The novel single-pill combination of allisartan isoproxil and sustained-release indapamide exerts synergistic antihypertensive effects.

Inclusion Criteria
  1. Patients 18-75 years old with mild to moderate essential hypertension;

  2. Patients who meet one of the following criteria when screening:

    1. Untreated patients (either newly diagnosed essential hypertension or those patients with a history of hypertension but have not been taking any antihypertensive drugs for at least 2 weeks before the first visit) must have an office msSBP ≥ 150 mmHg and < 180 mmHg and msDBP<110 mmHg;
    2. Patients who had not received regular treatment with allisartan isoproxil (240 mg/day) (less than 4 weeks of medication intake or a history of missing doses for 5 or more days within the 4 weeks before screening) with the msSBP of 140 mmHg≤ SBP <180 mmHg and DBP<110 mmHg;
    3. Patients currently receiving other antihypertensive agents (non-study medications for at least 2 weeks prior to screening) with the msSBP of 140 mmHg≤ SBP <180 mmHg and DBP<110 mmHg, and the clinician determined that it was appropriate to switch to allisartan isoproxil (240 mg/day);
    4. Patients who have been stably treated with allisartan isoproxil (240 mg/day) for at least 4 weeks with the msSBP of 140 mmHg≤ SBP <180 mmHg and DBP<110 mmHg.
  3. During randomization for the double-blind treatment period, msSBP should be 140 mmHg≤ SBP <180 mmHg and DBP<110 mmHg;

  4. Participants enrolled in the ABPM study should have 24-hour mean ambulatory blood pressure ≥130/80 mmHg after 4 weeks of monotherapy treatment;

  5. Patients who understand and sign the informed consent form.
