  • The mean difference in change in systolic blood pressure (BP) between the intervention and control communities from baseline to 1 year. [ Time Frame: Baseline to 1 year (HT phase) ] [ Designated as safety issue: No ]
  • Difference in number of a composite of major CV events (CV death, myocardial infarction (MI), stroke, congestive heart failure (CHF) and CV hospitalizations (unstable or new onset angina, CHF, or coronary revascularization) from baseline to 6 years. [ Time Frame: Baseline to 6 Years (CVD Phase) ] [ Designated as safety issue: No ]

  • The mean differences in calculated INTERHEART risk score from baseline to 1 year. [ Time Frame: Baseline to 1 year (HT Phase) ] [ Designated as safety issue: No ]
  • The difference in the proportion of participants on antihypertensive treatment and well-controlled from baseline to 1 year. [ Time Frame: Baseline to 1 year (HT Phase) ] [ Designated as safety issue: No ]
  • Difference in number of initiations, discontinuations, and up/down titrations of PolyCap formulations, as well as number of hospitalizations and CVD events from baseline to 1 year. [ Time Frame: Baseline to 1 year (HT Phase) ] [ Designated as safety issue: Yes ]
  • Difference in the number of individual components of the primary outcome (CV death, MI, stroke, CHF and CV hospitalizations, unstable or new onset angina, CHF, or coronary revascularization) from baseline to 6 years. [ Time Frame: Baseline to 6 Years (CVD Phase) ] [ Designated as safety issue: No ]

Health economic evaluations - measure/calculate the unit costs and the quantity used of each of the components of the intervention and in usual care in the participating countries. [ Time Frame: Baseline to 6 years ] [ Designated as safety issue: No ]
We will collect data that will allow us to determine (i) the costs of the suggested programs (i.e. intervention package) and the costs of what is being provided currently for CVD assessment and management in the communities studied (i.e. control).

Heart Outcomes Prevention and Evaluation 4
Heart Outcomes Prevention and Evaluation 4 (HOPE-4)

The overall objective of the HOPE-4 study, Phases (hypertension (HT) and cardiovascular disease (CVD)), is to develop and test a program for cardiovascular disease risk assessment and treatment involving: (1) simple screening and treatment guidelines implemented by non-physician health workers (NPHW); (2) single pill containing blood pressure and cholesterol lowering drugs; and (3) family or friends and mobile phone technology to help participants comply with the treatment regimen. This program has the potential to reduce major cardiovascular events by 35% over 6 years, as compared to usual care.

Study design: open-label, cluster randomized controlled trial design.

HT Phase: 50 urban and rural communities in Colombia and Malaysia will be randomized to participate in an intensive cardiovascular (CV) risk detection and control program by non-physician health workers (NPHW) or to care as usual for 12 months.

CVD Phase: Continuation and expansion of HT Phase to include a total of 190 urban and rural communities in countries within Asia (India, Malaysia, Philippines), South America (Colombia, Argentina), and Sub-Saharan Africa (South Africa, Tanzania, Rwanda) that will be allocated to participate in the intensive CV risk detection and control program by NPHW or to care as usual for a target of 6 years.

Communities will be randomized 1:1 with a central randomization list to either a) intervention or b) control.

Interventional
Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Hypertension
  • Cardiovascular Disease
  • Other: Intervention
    In intervention communities, management plans will be developed by the NPHW for all enrolled participants. The NPHWs will educate participants about CVD, HT treatment, lifestyle modifications and initiate therapy according to the modified WHO CVD risk-management algorithm, including referral of high-risk patients to physicians and safety monitoring where appropriate. Participants in intervention communities will have support from family or friends (treatment supporters) and will receive educational materials and treatment reminders using text-messaging, email, and printed materials, as appropriate for the participant and the community setting. Standard and half-dose Polycap formulations will be provided to the NPHWs and supervising physicians for participant treatment.
  • Other: Usual Care
    At initial screening, eligible participants will be provided with a brief information booklet/leaflet (customized to the community or region) regarding lifestyle modification and be advised to see their usual physician for care that is considered appropriate. No structured interventions will be employed.
  • Experimental: Intervention
    Intensive CV risk detection, counselling and follow-up program by non-physician health workers (NPHW); open-label fixed-dose combination pill therapy (Polycap) in accordance with treatment algorithm; use of treatment supporters and mobile phone technology to reinforce adherence.
    Intervention: Other: Intervention
  • Control - Usual Care
    Participants in control communities will be referred to usual care.
    Intervention: Other: Usual Care
