SECONDARY outcome

Timeframe: 15 months

Population: WHO defines pretreatment HIV drug resistance (PDR) as "DR that is detected in ARV drug-naive people initiating ART or people with prior ARV drug exposure initiating or reinitiating first-line ART. PDR is either transmitted or acquired drug resistance, or both". Thus, we did not report outcomes with TDR, instead we reported PDR as this could be determined but antiretroviral history was not available. Thus, PDR is reported in place of TDR. This included participants with PDR ≥10% at randomization.

We did not analyze and report outcome of people with TDR ≥10%, instead we reported pretreatment drug resistance (PDR) as this parameter could be determined but antiretroviral history was not reliably available. Thus, PDR ≥10% is considered below in place of TDR ≥10%. Chung et al. Lancet HIV 2020; 7: e104-12.

SECONDARY outcome

Timeframe: 24 months

Population: Analysis included 352 participants from Nairobi, including 332 with virologic suppression at month-12 of efavirenz-based ART who enrolled for a second year and 20 participants who experienced virologic failure by month-12 of efavirenz-based ART. Pretreatment drug-resistance was classified as: wild-type (0%), low-frequency (1-9%), high-frequency (10-100%). Virologic failure by month-24 of efavirenz-based ART, was compared between individuals with and without pretreatment drug-resistance.

The prespecified outcomes of this study included differences in the rate of virologic failure over 24 months of efavirenz-based ART between participants by frequency of drug-resistant variants detected by next-generation sequencing at enrollment. Drug-resistance frequency was defined as the proportion of a nucleotide variant encoding a drug-resistant codon in specimens with at least 100 viral templates sequenced. Virologic failure was defined as plasma HIV RNA of at least 400 copies/ml in sequential specimens or at the final study visit in participants prescribed efavirenz-based ART. \[Milne et al.

OTHER_PRE_SPECIFIED outcome

Timeframe: Enrollment

Population: Among the subgroup of enrollment samples with both OLA and CS testing, we compared mutation detection by each method at OLA codons and assessed mutations at non-OLA codons detected by CS. Only mutations with Stanford HIVDR Program drug resistance mutation scores ≥10 were included.

Rates of pre-treatment drug resistance among all study participants in the study were assessed by OLA but not by consensus sequencing (CS) due to the high cost of sequencing the entire population. However, all mutations detected by OLA were confirmed by CS in Seattle, and if not detected by CS were confirmed by next generation Illumina sequencing. Participants with any indeterminate OLA results were also sequenced to determine the genotype at the indeterminate codon.
