简要总结
The study design is an open-label, randomized controlled trial. The study will be conducted at study sites in Uganda and South Africa. The study population will include HIV-infected patients on first-line antiretroviral therapy with a recent viral load >1,000 copies/milliliter (or dried blood spot viral load >1,000 copies/milliliter). Eligible participants will be randomized to the WHO-based standard of care for management of virologic failure or immediate resistance testing to guide ART regimen decisions. The primary outcome of interest will be viral suppression (<200 copies/mL) at 9 months after study enrollment, and will be assessed using an intention to treat analysis, where missing or absent results will be considered failures. Secondary outcomes of interest will be viral suppression below the limit of assay detection, viral suppression on continuation of first-line (non-nucleoside reverse transcriptase inhibitor [NNRTI]-based) therapy, drug resistance at study conclusion, and mortality, among others. The overarching goal of this study is to determine whether addition of routine resistance testing, to guide management of virologic failure and sustain the successful completion of the HIV continuum of care, improves clinical outcomes and reduces costs for patients with virologic failure on first-line therapy in sub-Saharan Africa.

STUDY PROCEDURES FOR PARTICIPANTS RANDOMIZED TO STANDARD OF CARE ARM
A. Visit 1-SOC: Baseline Visit for Standard of Care Participants
At Study Visit 1, participants randomized to the SOC will complete the baseline questionnaire to collect sociodemographic, HIV clinical and treatment history, self-reported ART medication adherence, quality of life, and resource allocation data. Study staff will review participant records to collect data on clinic initiation start date, opportunistic infection history, ART initiation date, ART regimen history, CD4 count and viral load result histories. A single 10cc blood specimen will be drawn for storage for future testing for viral load, resistance testing, and drug therapeutic monitoring. Upon completion of the baseline questionnaire, participants will be referred to clinic counselors who will conduct adherence support counseling as per standard clinical procedures. A follow-up study visit will be scheduled 3 months from the baseline date (or at 1 month for pregnant participants only). Any interim clinical visits that are indicated by the clinic staff will be maintained. The participant will be instructed to continue their current ART regimen until at least the next clinical visit.
B. Visit 2A-SOC: Repeat Viral Load Testing Visit
At Study Visit 2A, participants in the SOC arm will undergo blood collection for viral load testing in keeping with WHO guidelines. An additional tube 10cc tube will be drawn for storage for future analyses. A study questionnaire will be administered to assess self-reported ART medication adherence. No other procedures are scheduled at this visit. Participants will be notified that study staff will contact them as soon as their results are available, to request return to clinic for further management. The participant will be instructed to continue their current ART regimen until at least the next clinical visit. As soon as the viral load result is available, study participants will be contacted and requested to return to clinic for review. If the viral load is indeterminate or not completed for any reason, study staff will request that the participant return for a repeat viral load test.
