Abstract
BackgroundBlood pressure (BP) control among treated patients in Africa is very suboptimal, with low levels of combination therapy use and therapeutic inertia being among the major barriers to effective control of hypertension. The VERONICA-Nigeria study aims to evaluate, among Black African adults with hypertension, the effectiveness and safety of a triple pill-based treatment protocol compared to Nigeria hypertension treatment protocol for the treatment of hypertension. MethodsThis study involves a randomised, parallel-group and open-label trial. Adults with uncontrolled hypertension (n=300), untreated or receiving monotherapy, with no contraindication to study treatments will be randomly assigned 1:1 to treatment with a triple pill based-treatment protocol or Nigeria hypertension treatment protocol. Follow-up is for 6 months, with interim follow up visits at month 1, 2, and 3. In a non-comparative extension treatment period, participants completing the 6 months randomised period and on ≤3 BP-lowering drugs will receive treatment with the triple pill-based treatment protocol for 12 months. The primary outcome is change in home mean SBP from baseline to month 6, and key secondary efficacy outcome is percentage of participants with clinic BP <140/90 mmHg at month 6. The primary safety outcome is discontinuation of trial treatment due to adverse events from randomization to month 6. Economic evaluation will be conducted to assess the cost-effectiveness of the triple pill-based treatment protocol, and process evaluation will be conducted to understand the context in which the trial was conducted, implementation of the trial and interventions and mechanisms of effect, and potential barriers and facilitators to implementing the intervention in clinical practice. ConclusionThe VERONICA-Nigeria trial will provide evidence of effectiveness and safety of the triple-based treatment protocol for the pharmacological management of hypertension, in Black African adults.
