LPV/r+3TC

In the GARDEL study comparing LPV/r+3TC with LPV plus two NRTIs the LPV/r+3TC regimen demonstrated non-inferiority at 48 weeks. However, because of the pill burden of LPV/r (3 pills taken twice daily), twice daily dosing, and higher rates of GI side effects compared to other PIs, the DHHS panel recommends that LPV/r plus 3TC be considered only in patients who cannot take TAF, TDF or ABC (Cahn 2014).

Efficacy in clinical trials:

  • In the GARDEL study, 426 ART-naive patients were randomized to receive twice-daily LPV/r plus either open-label 3TC (twice daily) or two NRTIs selected by the study investigators. At 48 weeks, a similar number of patients in each arm had HIV RNA <50 copies/mL, meeting the study’s non-inferiority criteria. The LPV/r+3TC regimen was better tolerated than the LPV/r plus 2 NRTI regimen (Cahn 2014).
