Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The WHO has recommended TB preventive therapy (TPT) for children living with HIV (CLHIV) and household contacts of people living with TB, however, the scale-up and implementation of TPT has been sub-optimal globally particularly in children. A safe and effective short-course TPT regimen, 3HP (rifapentine and isoniazid given once weekly for three months), is available but there is a lack of child-friendly formulations resulting in increased pill burden and there is a need to improve acceptability and adherence among children. The introduction of a dispersible rifapentine formulation has potential to improve uptake, treatment adherence and completion.

Overall goal is to generate critical knowledge to improve delivery of TPT and, more specifically, of dispersible 3HP, in children in routine programs.

This evaluation will create an important understanding of TPT uptake and completion among children and assess the impact of the introduction of a dispersible 3HP formulation. These results will provide actionable information for improving service delivery and the scale-up of TPT in the respective countries.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Children <12 years who are eligible for TPT - HHC

No intervention. Clinic record review: Data will be retrospectively abstracted from routine medical files using a standardised data collection tool that will document TPT uptake and outcomes

No interventions assigned to this group

Policy makers/Program managers

No intervention. Qualitative study: We will recruit a purposive sample of policy makers, healthcare workers and caregivers who will be interviewed to evaluate buy-in and explore their insights and experiences on the different TPT regimens and formulations.

Healthcare Workers

No intervention. Qualitative study: We will recruit a purposive sample of policy makers, healthcare workers and caregivers who will be interviewed to evaluate buy-in and explore their insights and experiences on the different TPT regimens and formulations.

Caregivers

No intervention. Qualitative study: We will recruit a purposive sample of policy makers, healthcare workers and caregivers who will be interviewed to evaluate buy-in and explore their insights and experiences on the different TPT regimens and formulations.

No interventions assigned to this group

Pharmacy managers/pharmacists

No intervention. Clinic assessment: We will assess provider barriers and facilitators to prescribing the new dispersible 3HP (single dispersible formulations of isoniazid and rifapentine) through a survey tool which will collect information on the flow of TPT from national supply to the clinic and dispensing to the child.
