HIV-1 TREATMENT REGIMENS
POWERED BY DOLUTEGRAVIR AT THE CORE
When prescribing an HIV-1 treatment, choose a dolutegravir-based regimen
TIVICAY and TIVICAY PD are human immunodeficiency virus type 1 (HIV-1) integrase strand transfer inhibitors (INSTIs) indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults (treatment-naïve or -experienced) and in pediatric patients (treatment-naïve or -experienced, but INSTI-naïve) aged ≥4 weeks and weighing ≥3 kg
TIVICAY is indicated in combination with rilpivirine as a complete regimen for the treatment of HIV-1 infection in adults to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA <50 copies/mL) on a stable antiretroviral regimen for ≥6 months with no history of treatment failure or known substitutions associated with resistance to either antiretroviral agent
Proven high barrier to resistance*†
in treatment-naïve patients and
with baseline resistance1-5
Resistance was a secondary endpoint for SINGLE, SPRING-2, FLAMINGO, and SAILING

*Based on the SINGLE double-blind (to Week 96; open-label from Week 96 to Week 144) trial comparing DTG 50 mg once daily + ABC/3TC (n=414) vs EFV/TDF/FTC once daily (n=419). No patients in the treatment arm receiving DTG in the SINGLE trial had a detectable decrease in susceptibility to DTG or background NRTIs (ABC/3TC) in the resistance analysis data set (n=11 with HIV-1 RNA >400 copies/mL at failure or last visit and having resistance data). Two patients with virologic failure in the SINGLE trial had treatment-emergent G/D/E193D and G193G/E integrase substitutions at Week 84 and Week 108, respectively, and 1 patient with 275 copies/mL HIV-1 RNA had a treatment-emergent Q157Q/P integrase substitution detected at Week 24.
†Based on data from SAILING, a 48-week, randomized, double-blind, active-control trial comparing DTG 50 mg once daily + BR (n=357) vs RAL 400 mg twice daily + BR (n=362) in treatment-experienced, INSTI-naïve adults with HIV-1. BR was investigator selected and consisted of up to 2 agents, including at least 1 fully active agent. All patients had at least 2-class antiretroviral treatment resistance (not including INSTIs); 49% were resistant to ≥3 ART classes. No patients with treatment-emergent integrase substitutions in the arm receiving DTG (n=5) had reduced susceptibility (>2-fold change) to DTG. Substitutions with <2-fold decreased susceptibility: L74L/M/I, Q95Q/L, V151V/I (n=1 each), and R263K (n=2).
3TC=lamivudine; ABC=abacavir; ART=antiretroviral therapy; BR=background regimen; DTG=dolutegravir; EFV=efavirenz; FTC=emtricitabine; INSTI=integrase strand transfer inhibitor; NRTI=nucleoside reverse strand transfer inhibitor; RAL=raltegravir; TDF=tenofovir disoproxil fumarate.
