Measure
BIC Arm
The Intervention Arm ART regimen is a fixed-drug combination of a single tablet co-formulated regimen containing Bictegravir 50mg Emtricitabine 200mg and tenofovir alafenamide 25mg (BIC/FTC/TAF; Biktarvy®) that will be taken twice a day during rifampicin-containing TB treatment and 2 weeks after stopping TB treatment, thereafter the BIC/FTC/TAF single tablet co-formulation will be taken once daily.
DTG Arm
Dolutegravir 50mg /Lamivudine 300mg/ Tenofovir 300mg (TLD- fixed-drug combination single tablet) plus Dolutegravir 50mg evening dose during TB treatment and for two weeks after completion of TB treatment, then TLD once daily thereafter- as per Standard of Care (SOC)
