Real-World Experience
Real-World Studies Supporting Findings From Phase III Trials1-17*
*All data below are reported as available, from a literature search up to October 2020, for studies including patients with no known or suspected resistance to integrase inhibitors or lamivudine. Available data shows:

Between 0 and 2.3% VF in studies with available data.2,6-8,10,14,15,17
Includes studies reporting applicable effectiveness outcomes for >50 patients receiving DTG + 3TC

High Barrier to Resistance
Dovato has demonstrated a high barrier to resistance in 874 patients across eight-real world switch studies1-8,11,15,17

Low Rate of Treatment Discontinuations
Between 1.5 and 6.2% discontinued due to AEs in studies with available data2,5-8,10,15,17
Percentage calculated based on overall N on DTG + 3TC as the denominator. Only those studies that include >50 patients on DTG + 3TC and report data on treatment discontinuation due to AEs have been included
DTG 50 mg + 3TC 300 mg used in the GEMINI-1 and -2, and real-world studies
*From a literature search, up to October 2020, for studies including patients with no known or suspected resistance to INIs or 3TC
RWE complements data from RCTs and builds confidence in the effectiveness and safety of new treatments in clinical practice.
Real-world Effectiveness Studies*
Support findings from Phase III RCTs*†
- Low risk of VF
- High barrier to resistance
- Low rate of treatment discontinuations

DTG 50 mg + 3TC 300 mg used in the GEMINI-1 and -2, and real-world studies
*From a literature search, up to October 2020, for studies including patients with no known or suspected resistance to INIs or 3TC.
†Please note each study may not have reported each clinical endpoint of VF, emergent resistance or Treatment discontinuations
DTG + 3TC has been evaluated across diverse patient populations in clinical trials and real-world studies*1-12

DTG 50 mg + 3TC 300 mg used in the GEMINI-1 and -2, and real-world studies
*From a literature search, up to October 2020, for studies including patients with no known or suspected resistance to INIs or 3TC
* From a literature search, up to October 2020, for studies including patients with no known or suspected resistance to integrase inhibitors or lamivudine.2-13
