## Brief Summary

Hypertension is a leading cause of morbidity and mortality globally. Although multiple drugs are frequently used to treat it, in the South Asian context, evidence is lacking on best drug combinations. This trial aims to compare efficacy of three single-pill combinations of two anti-hypertensive agents on 24-hour ambulatory systolic blood pressure among 1968 individuals with hypertension. The trial is a single-blind randomized controlled trial spread across 37 hospitals in India.

Single Pill combinations (SPCs): 1) Amlodipine + Perindopril, 2) Perindopril + Indapamide, 3) Amlodipine + Indapamide

## Detailed Description

This is a multi-centre, individual randomized single-blind, parallel group, three-armed superiority trial to compare the efficacy of three different single-pill combinations of antihypertensive therapies (Amlodipine/Perindopril, Perindopril/Indapamide, and Amlodipine/Indapamide)on 24-hour ambulatory BP levels in Indians.

## Eligibility

- **Minimum age:** 30 Years
- **Maximum age:** 79 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

1. Age 30-79 years AND

12. Pregnancy or those of child-bearing age who are not taking reliable contraception.
13. History of Gout.
14. Serum potassium \< 3.5mmol/L at screening.

## Arms

- **Arm 1** (EXPERIMENTAL) — (Arm 1 compare to Arm 2 compare to Arm 3) - Treatment Period 1 (Enrollment - 2 months) - Single Pill Combination of Amlodipine 5 mg and Perindopril 4 mg once daily, orally Treatment Period 2 (2 months - 6 months) - Single Pill Combination of Amlodipine 10 mg and Perindopril 8 mg once daily, orally
- **Arm 2** (EXPERIMENTAL) — (Arm 1 compare to Arm 2 compare to Arm 3) - Treatment Period 1 (Enrollment - 2 months) - Single Pill Combination of Perindopril 4 mg and Indapamide 1.25 mg once daily, orally Treatment Period 2 (2 months - 6 months) - Single Pill Combination of Perindopril 8 mg and Indapamide 2.5 mg once daily, orally
- **Arm 3** (EXPERIMENTAL) — (Arm 1 compare to Arm 2 compare to Arm 3) - Treatment Period 1 (Enrollment - 2 months) - Single Pill Combination of Amlodipine 5 mg and Indapamide 1.5 mg sustained release once daily, orally Treatment Period 2 (2 months - 6 months) - Single Pill Combination of Amlodipine 10 mg and Indapamide 1.5 mg sustained release once daily, orally

## Interventions

- **Amlodipine + Perindopril** (DRUG) — Single pill combination of dual antihypertensive agent
- **Perindopril + Indapamide** (DRUG) — Single pill combination of dual antihypertensive agent

## Primary Outcomes

- **Proportion of patients classified as "responders"** _(time frame: Clinic BP as measured at baseline, 2 month, 4 month and 6 month)_
- **Micro- and macro-albuminuria** _(time frame: Change in serum albumin measured at baseline and 6 month)_
- **Fasting blood glucose** _(time frame: Change in fasting blood glucose measured at baseline and 6 month)_
