Detailed Description
Intracerebral haemorrhage (ICH) is the most serious and least treatable form of stroke, accounting for at least 10% of the 20 million new strokes that occur globally each year. Survivors of ICH are at high risk of recurrent ICH and other serious cardiovascular events.
While there is strong evidence that this risk can be reduced by lowering the blood pressure (BP) of patients after ICH, many patients with ICH do not receive BP-lowering treatment long-term unless BP levels are particularly high, and many do not receive BP combination therapy.
The aim of this study is to assess the safety and efficacy of a combination of fixed low-dose generic BP lowering agents, as a "Triple Pill" strategy on top of standard of care for the prevention of recurrent stroke in patients with a history of ICH and high normal or low grade hypertension. The study is a large-scale, international, double-blind, placebo-controlled, randomised controlled trial.

- No clear contraindication to any of the study treatments
- Provision of written informed consent
Exclusion Criteria:
Taking an ACE-I that cannot be switched to any of the following alternatives:
- telmisartan 20 or 40mg, amlodipine 2.5 or 5mg, indapamide 1.25mg, or
- an equivalent class (ARB, CCB or thiazide [TZ]-like diuretic), or
- a BB
- Contraindication to any of the study medications, in the context of currently prescribed BP-lowering medication
- Unable to complete the study procedures and/or follow-up
- Females of child-bearing age and capability, who are pregnant or breast-feeding, or those of child-bearing age and capability who are not using adequate birth control
- Significant hyperkalaemia and/or hyponatremia, in the opinion of the responsible physician
- Estimated glomerular filtration rate (eGFR) <30mL/min/1.73m2
- Severe hepatic impairment (alanine aminotransferase [ALT] or aspartate aminotransferase [AST] >3x the upper limit of normal [ULN])
- Any other condition that in the opinion of the responsible physician or investigator renders the patient unsuitable for the study (e.g. severe disability [i.e. simplified modified Rankin Scale (smRS) of 4-5] or significant memory or behavioural disorder)
Exclusion Criteria for MRI (as applies)
• Any MRI contraindication (e.g. metallic implants, claustrophobia, etc) or participant refusal.
