Brief Summary

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

This cluster-randomized trial tests a differentiated care model for HIV-positive individuals not on ART during a home-based HIV testing campaign in rural Lesotho, Southern Africa. In intervention clusters, patients are offered a differentiated ART delivery package with two features. Firstly, drug-refill and follow-up are provided by village health workers (VHW), reducing clinic visits to twice a year for laboratory assessment. Secondly, participants have the option of receiving individually tailored adherence reminders and viral load result notifications via SMS.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The VIBRA trial is a cluster randomized controlled, open-label, superiority trial in a resource-limited setting. The trial is linked to a another trial, the HOSENG (HOme-based SElf-testiNG) trial, that is described elsewhere (NCT03598686). Together, they consitute the GET ON (GETing tOwards Ninety) research project. The HOSENG study, with its home-based HIV testing campaign, provides the recruitment platform for the VIBRA study. The reasons for this interlinked design are: a) potential study participants for VIBRA trial (HIV-positive individuals not on ART) are to be recruited during a home-based HIV testing campaign and hence, it allows us to assess the entire HIV care cascade in one larger project, and b) both trials rely on interventions involving VHWs, who need to be randomized and specifically trained. Therefore, it is efficient and feasible to run both trials parallel and randomize at one time point only. The rational for a cluster randomized design is the reliance of the trial on the VHWs and, thus, the high risk of cross-contamination between the study arms if randomization would be done at individual level.
