Why 2DR?

AE, adverse event; DDI, drug-drug interaction; HCP, healthcare professional; SoC, standard of care

Reduce potential impact of long-term

exposure to multiple ARVs

Less potential for AEs?

“As much as needed, as little as possible”

“Why take 3 (or 4), when 2 can do?”

Why 2DR?

Potential to reduce DDIs

Ageing patients

Co-morbidities

Potential preservation of future

treatment options

Clinical profile of newer agents allow

us to investigate 2DR

changed the focus from saving lives to chronic

management1

NRTI, is approved,

HIV2

of third agents

marked the

beginning of the era

Life expectancy among PLHIV is

approaching normal

Life expectancy in patients on ART has increased to near normal1

However, even with early treatment and access to care, an 11.8-year

gap in life expectancy remains for HIV-infected compared with HIV-

uninfected individuals2

PLHIV will be on ARV therapy for decades; the mean estimated

duration of lifetime treatment in 2012 was 39.1 years3

Among PLHIV, the prevalence of comorbidities and

comedication use increases with age1

Proportion of patients having ≥ 1 comorbidity or receiving

≥ 1 comedication increased with age1

As part of the Swiss HIV Cohort Study, Hasse et al. investigated how the number of

comorbidities and the number of non-AIDS comedications taken by HIV-positive patients

differed with age (8444 PLHIV in cohort)

• No treatment-emergent INSTI mutations or NRTI mutations were

observed among participants who met CVW (confirmed virologic

withdrawal) criteria

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.

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

DTG + 3TC vs the 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

– Change in renal and bone biomarkers significantly favors DTG + 3TC

• These data support DTG + 3TC as an effective option for the treatment of HIV-1

infection

• NTDs are congenital abnormalities affecting the brain, spine, or

spinal cord and result from failure of complete closure of the neural

tube, which usually occurs by Day 28 of pregnancy.

• Most common NTDs are spina bifida (usually compatible with life)

and anencephaly (usually incompatible with life).

• Diagnosis is through imaging or blood tests during pregnancy, or

made at birth.

• Risk factors include: Genetic factors, Folate/B12 deficiency,

Obesity, Diabetes, Medications (e.g. anti-epileptics)

• Prevalence rates of NTDs can vary widely between regions

– UK: 0.13%

– Europe: 0.09%

– USA: 0.02 – 0.2%

– India: 0.45%

– Africa: 0.05 – 0.75%

– ViiV sponsored clinical trials: 74 pregnancies - no NTDs reported.

– Post-marketing reports: Approximately 500 pregnancy outcomes - 3 NTDs

reported.

– Non-ViiV Data: Approximately 4,150 pregnancies with approximately 880

exposed at time of conception. From the Botswana cohort: 4 NTDs with

exposure at conception, 1 NTD with exposure during pregnancy (8 weeks

GA).

• From 1 May-15 July, there were 2 more NTDs; 1 in an infant exposed to DTG started during pregnancy (8 weeks GA) and 1 birth to an HIV-uninfected woman- NTDs in DTG started in pregnancy: 1/3104 (0.03%, 95% CI

0.01%, 0.18%)

Update since 1 May 2018

Updated prevalence of DTG exposure at conception is 4/596 (0.67%, 95% CI 0.26%, 1.7%)-- 95% CI still does not overlap with any other exposure group

Page 50: UK CAB 2018 · Reduced cost9,10 • Reduced drug costs, and long-term care/societal costs • Improvements in access Improved quality of life11 • Improvements in patient satisfaction

Updated Analysis Plan

• Next formal analysis will occur after 31 March 2019– Will include women already exposed to DTG from conception

prior to recent guideline change

– Plans in place to expand from 8 to 18 sites, increasing from 45% to 72% of births in the country

• Final analysis in 2019 to include:– NTDs

– All major malformations

– Other adverse birth outcomes (stillbirth, preterm, SGA, NND)

Projections for March 2019

• With expanded surveillance to 18 sites, we estimate ~ 1226 births with exposure to DTG from conception by end of March 2019

With 0 more NTDs, the lower CI overlaps with the upper CI for other ART at conception (0.21%), EFV at conception (0.15%) and with HIV-uninfected (0.13%)

With 1 more NTD, the lower CI overlaps with the upper CI for other ART at conception (0.21%)

Conclusion

• We have identified a concerning preliminary early signal for DTG and neural tube defects that requires further data to confirm or refute– Based on only 4 cases (though 95% confidence intervals do

not overlap with other exposure groups)

– Absolute prevalence difference is small (~ 0.8%)

– The 4 different defects among infants exposed to DTG at conception is unusual

DTG and Weight Gain – Summary

See slide notes for references

• Weight gain has been associated with ARV use,1–6 and is mentioned in the SmPCs of many

commonly used ARVs7–18

• Increased weight is not mentioned in the Tivicay (DTG) SmPC19

• Despite ART-related weight gain, HIV-positive patients generally have similar or lower weight

than HIV-negative persons of a similar age5,6,20

• Data are not available to determine whether observed weight gain is reflective of a return to

health or is clinically significant

• Data on weight gain with DTG are limited, largely consisting of case reports21 and

retrospective, observational studies22–24

• Two comparative studies reported weight/BMI gain with DTG-based regimens23,24

‒ One large study found significant BMI increases after 12 months of treatment with DTG, EVG,

RAL, DRV and RPV, with little difference between them23

‒ Another study found significantly greater weight gains with INI- or PI-based regimens versus EFV,

with most notable increases after 18 months of DTG/ABC/3TC24

• In a post-hoc weight analysis of the NEAT-022 study in virologically suppressed patients with high

CV risk, switch from Pl/r to DTG was associated with a small but statistically significant weight &

BMI gain over 48 weeks; risk of weight gain was higher amongst individuals switching from

darunavir/r vs other protease inhibitors.25

• Weight changes will continue to be monitored and evaluated in current and future DTG RCTs
