BEYOND VIRAL SUPPRESSION

DOVATO HAS DEMONSTRATED NO CLINICALLY SIGNIFICANT METABOLIC HEALTH* IMPACT IN SWITCH PATIENTS

Metabolic Health Parameters Reported in Studies did not determine if these changes translate into clinical differences

Metabolic health outcomes in the TANGO and SALSA studies
  • Small changes with generally favourable lipid results vs TAF-containing regimens

  • Similar small increases in metabolic syndrome across arms

  • Similar small changes in fasting glucose across arms

  • Similar small increases in HOMA-IR levels across arms

OUT TO 144 WEEKS IN SWITCH PATIENTS[1,2]
Metabolic health outcomes in the TANGO and SALSA studies
  • Changes in lipid parameters were small and similar between treatment arms

OUT TO 48 WEEKS IN SWITCH PATIENTS[3]
RUMBA
  • Small changes in HDL cholesterol favouring DOVATO vs. BIC/FTC/TAF

  • Similar changes in other lipid parameters across arms

  • Similar changes across HOMA-IR across arms

OUT TO 48 WEEKS IN SWITCH PATIENTS[4]

*“Metabolic health” is an umbrella term for several metabolic variables that are associated with developing cardiometabolic disease.
Metabolic syndrome defined by the International Diabetes Federation as a combination of risk factors for cardiovascular disease.[4]
Defined as homeostatic model assessment of insulin resistance (HOMA-IR) ≥2.[1]

IN CLINICAL STUDIES, DOVATO WAS ALSO ASSOCIATED WITH SMALL WEIGHT CHANGES

WHAT WEIGHT CHANGES HAVE BEEN OBSERVED WITH OTHER ARTs?

  • Weight Gain: Treatment Naïve

    INCREASED WEIGHT GAIN WITH TAF AND INIs IN TREATMENT-NAÏVE PATIENTS

    In a Pooled Analysis of 8 Treatment-Naïve RCTs (N=5,680)[8]:

    TAF Was Associated With Weight Gain at 96 Weeks

    LS mean weight change over time in patients taking NRTIs*[8]

    TAF was also associated with an increased risk of a clinically meaningful† weight gain compared with ABC (OR, 1.90 [95% CI: 1.25–2.88]; P=0.003) and TDF (OR, 1.47 [95% CI: 1.14–1.90]; P=0.003).

    BIC and DTG Were Associated With a Significantly Increased Risk of Weight Gain Compared With Boosted EVG at 96 Weeks

    LS mean weight change over time in patients taking INIs*[8]

    Adapted from Sax et al, 2020.[8]

    BIC and DTG (OR, 1.82 [95% CI: 1.24–2.66]; P=0.002), and EVG/c (OR, 1.36 [95% CI: 1.04–1.78]; P=0.026), were also associated with an increased risk of a clinically meaningful† weight gain compared with EFV.

    Asterisks are colour-coded to match the respective comparator and denote P≤0.05 compared with EVG/c.[8]

    LS=least squares; OR=odds ratio.
    *Multivariate model; stepwise model selection was used to identify baseline risk factors.[8]
    ≥10% weight gain.
