Which of the following is NOT a standard HAART regimen for treatment-naïve HIV patients?

• A. NNRTI + 2 NRTIs
• B. PI + 2 NRTIs
• C. INSTI + 2 NRTIs
• D. NNRTI + PI

Answer: (D)

Starting HIV treatment uses a three-drug plan with two NRTIs forming the backbone and a third drug from NNRTI, INSTI, or boosted PI. This backbone of two NRTIs is essential for potency and resistance control. Examples include two NRTIs plus an NNRTI (like efavirenz), two NRTIs plus an INSTI (like dolutegravir), or two NRTIs plus a boosted PI (like darunavir/ritonavir). The option that combines an NNRTI with a protease inhibitor without any NRTIs lacks that essential backbone, so it isn’t a standard initial regimen for treatment-naïve patients. That’s why it’s not used as standard HAART.
