Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients in the intervention arm will start on the lower dose of the drug under investigation with the option to move to the higher dose if blood pressure is not controlled to the responsible clinician's satisfaction. Each dose version is taken as one tablet once a day for a total period of 6 months.
Components of each dose version are as follows:
Low Dose: Telmisartan 20mg, Amlodipine 2.5mg, Chlorthalidone 12.5mg
High Dose: Telmisartan 40mg, Amlodipine 5mg, Chlorthalidone 25mg

Control group
Active

Outcomes
Primary outcome [1] 288203 0
Proportion of patients achieving target blood pressure (BP) at the end of 6 months follow-up: systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) < 90 mmHg (SBP < 130 mmHg and DBP < 85 mmHg for patients with diabetes and chronic kidney disease).
BP will be measured using automated BP machines (Omron) during the trial visit using standardised BP measurement protocols (e.g. sitting, 2 measurements taken 5 minutes apart)

Secondary outcome [1] 299597 0
Proportion of patients reaching target BP: SBP < 140 mmHg and DBP < 90 mmHg (SBP < 130 mmHg and DBP < 85 mmHg for patients with diabetes and chronic kidney disease).
BP will be measured using automated BP machines (Omron) during the trial visit using standardised BP measurement protocols (e.g. sitting, 2 measurements taken 5 minutes apart)

Secondary outcome [2] 299598 0
Mean change in SBP and DBP
BP will be measured using automated BP machines (Omron) during the trial visit using standardised BP measurement protocols (e.g. sitting, 2 measurements taken 5 minutes apart)
Timepoint [2] 299598 0
6 months
Secondary outcome [3] 299599 0
Tolerance to treatment will be assessed by comparing the rates of medication discontinuation, due to side effects, in both arms of the trial.
No increased side effects are expected beyond those expected for the individual medications taken either as components of the Triple Pill or the individual medications taken in the usual care arm. Cessation of medication due to side effects will be assessed by asking the patient why (if relevant) they have stopped taking their medication.
Timepoint [3] 299599 0
6 months
Secondary outcome [4] 299600 0
Use of health care services (hospitalisations, medical consultations, tests).
Use of such services will be assessed by patient recall of relevant health service utilisation during the trial period. This data will be collected by the study nurse during the trial visit.
Timepoint [4] 299600 0
6 months
Secondary outcome [5] 299601 0
Self-reported BP lowering medication use (7-day recall) - adherence defined as taking the drug for at least 4 out of the previous 7 days.
Medication use will be ascertained during the study visit by patient recall of how many times they took their medication over the last 7 days.
Timepoint [5] 299601 0
6 months
Secondary outcome [6] 299602 0
Quality of life will be assessed using the EQ5D health assessment questionnaire.

Eligibility
Key inclusion criteria
* The investigator is satisfied that the patient has persistent hypertension (SBP>140mmHg and/or DBP>90mmHg; or SBP>130mmHg and/or DBP>80mmHg in patients with diabetes mellitus or chronic kidney disease) requiring initiation of pharmacological treatment (in patients not taking drug therapy) or up-titration of pharmacological treatment (in patients taking single drug therapy)

*Trial Investigator is unsure as to whether a Triple Pill based therapy or usual care is better.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
*on 2 or more BP lowering drugs
* severe or uncontrolled hypertension (SBP > 180mmHg and/or DBP > 110 mmHg)
*Accelerated hypertension or hypertension at a level where the physician feels that slower up-titration of treatment is appropriate (e.g. elderly patients)
*Contraindication to any of the components of the Triple Pill
*Pregnancy, breast feeding, childbearing potential not on effective medically accepted method of child birth control.
*Unstable medical condition or known situation where medication regimen might be altered for a significant length of time, e.g. current acute cardiovascular event, planned coronary bypass graft operation, dialysis.
*Participants with clinically significant abnormal laboratory value judged to be unsuitable for trial participation by the investigator.

Summary
Brief summary
The study is a prospective, open, randomised controlled clinical trial (n=700) of a combination blood pressure lowering pill (“Triple Pill”)-based strategy compared to usual care among individuals with newly diagnosed hypertension on no or minimal drug therapy, augmented by a cost-effectiveness analysis and a formal process evaluation.
The key hypothesis tested is that there is no difference in the proportion of patients reaching their target blood pressure at 6 months compared to usual care.
