Why investigate a 2-drug regimen?

No one should take more medicine than they need

A 20-year old starting a 3-drug regimen (3DR) may be on therapy for nearly 6

decades, which translates to more that 60,000 doses of individual medications.1

Managing comorbidities, DDIs and potential long-term effects of treatment are

important considerations

1. The Antiretroviral Therapy Cohort Collaboration. Survival of HIV-positive patients starting antiretroviral therapy between 1996 and 2013: a collaborative analysis of cohort

studies. Lancet HIV. 2017;4(8):e349-e356

2. Marcotullio S, et al. EACS 2017, poster PE25/9

ARV, antiretroviral; PLHIV, people living with HIV

The Positive Perspectives Survey highlighted that 72% (n=783/1085) of

PLHIV worry about the long-term impact of their medicines on their bodies2

The potential benefits associated with 2-drug regimens (2DRs) include

reduced ARV exposure and potential for toxicities, drug preservation for

future treatment options and increased treatment access

3DRs achieve viral suppression by targeting two different intracellular viral

replication processes; 2DRs can be expected to achieve the same as they also

target two distinct viral replication processes

• The requirement for lifelong ART for HIV infection has highlighted interest in

2DRs to minimize cumulative drug exposure1

• Lower ARV exposure may translate to less long-term drug toxicity

• The potency, safety and high resistance barrier of DTG make it an optimal core

agent for 2DRs

• The safety, tolerability and efficacy of 3TC make it a reliable partner for initial

HIV-1 treatment

• Previous pilot studies have evaluated DTG + 3TC as a complete 2DR in

treatment-naive participants

– PADDLE: 90% (18/20) had VL <50 c/mL at Week 482

– ACTG A5353: 90% (108/120) had VL <50 c/mL at Week 243

• DTG + 3TC was evaluated vs a 3-drug regimen (3DR) DTG + TDF/FTC for

treatment-naive patients with HIV-1 infection through 48 weeks

Confirmed virologic withdrawal criteria is defined as a second and consecutive HIV-1 RNA value meeting virologic non-response or rebound. Virologic non-response is defined as either a decrease in

plasma HIV-1 RNA of less than 1 log10 c/mL by Week 12 with subsequent confirmation unless plasma HIV-1 RNA is <200 c/mL, or confirmed plasma HIV-1 RNA levels ≥200 c/mL on or after Week 24.

Virologic rebound is defined as confirmed rebound in plasma HIV-1 RNA levels to ≥200 c/mL after prior confirmed suppression to <200 c/mL.

aThe adjusted mean is the estimated mean change from baseline in each fasting lipid at Week 48 in each arm calculated from an ANCOVA model adjusting for the

following covariates/factors: study treatment, baseline plasma HIV-1 RNA, baseline CD4+ cell count, age and fasting lipids at baseline. Multiple imputed dataset

(missing at random). Absolute values based on summaries. Baseline values are represented by the main legend colors, with changes at Week 48 represented by

shaded areas (increases) or dashed lines (decreases).

Page 20: Non-Inferior Efficacy of Dolutegravir (DTG) plus ... · •The requirement for lifelong ART for HIV infection has highlighted interest in 2DRs to minimize cumulative drug exposure1

• GEMINI-1 and GEMINI-2 results demonstrate non-inferior virologic efficacy for

the 2DR DTG + 3TC vs a 3DR DTG + TDF/FTC at Week 48

• Both DTG + 3TC and DTG + TDF/FTC were associated with low rates of

confirmed virologic withdrawals through Week 48

– No treatment-emergent INSTI or NRTI mutations were observed among participants

who met CVW criteria

• Overall safety and tolerability profile at Week 48 was comparable between the

2 regimens

– Fewer drug-related AEs with DTG + 3TC

– Statistically significant change in renal and bone biomarkers from baseline favours

DTG + 3TC vs DTG + TDF/FTC

• GEMINI-1 and GEMINI-2 data support DTG + 3TC as a 2DR for the treatment of

HIV-1 infection in treatment-naïve HBV-negative patients with viral loads up to

500,000 copies/mL

Warnings/precautions: Risk of hypersensitivity reactions. Discontinue dolutegravir and other suspect agents immediately if suspected. The two-drug regimen of dolutegravir and lamivudine is only suitable for the treatment of HIV-1 infection where there is no known or suspected resistance to the integrase inhibitor class, or to lamivudine. Risks of osteonecrosis, immune reactivation syndrome. Monitor LFTs in Hepatitis B/C co-infection and ensure

effective Hepatitis B therapy. Caution with metformin: monitor renal function and consider metformin dose adjustment. Use with etravirine requires boosted PI or increased dose of dolutegravir. Use with Mg/Al-containing antacids, calcium, multivitamins or iron requires dosage separation. Pregnancy/ lactation: Not recommended. Avoid breast-feeding. Side effects: See SmPC for full details.
