Disclosures

  • Brad Hare:
  • None
  • Annie Luetkemeyer:
  • Research support from ViiV

Goals/Format

  • Explore three cases in ART management
  • Elicit audience opinions
  • Expert panel reflections

Patient 1

  • 38 year old man, no medical history
  • Being routinely tested for HIV every three months;

last negative test 3 months ago, August 2017

  • In November 2017, HIV test is positive
  • CD4=640 cells/uL, HIV-1 RNA = 31,000 c/mL
  • HIV-1 genotype is sent, and still pending
  • Patient expresses desire to initiate ART immediately

(and you agree)

Audience Preliminary Vote

  • Given the many options for ART, would you

initiate TAF/FTC (Descovy) + dolutegravir (Tivicay)?

– (A) YES, I would give TAF/FTC + DTG. – (B) NO, I would recommend something else.

Case 1:

Susa Coffey

Yes, comfortable initiating TAF/FTC + dolutegravir

Case 1: Starting DTG + TAF/FTC is appropriate

. Pt Pt with early HIV, CD4=640, VL=31,000; genotype is pending.

  • Mountains of data and experience with DTG + 2 NRTIs in

initial ART; preferred regimen

  • If concern for transmitted resistance (R)
  • How likely?
  • How likely to impact this regimen in NEXT 2-3 WEEKS?
  • TDR present in ~15%, NRTI mutation ~7%
  • K65R rare, M184V ~4-5%
  • Major INSTI mutations RARE
  • Almost certainly has fully-active DTG and TAF, fully
  • r perhaps partially effective FTC; this should be sufficient

Menza TW et al, AIDS 2017.

Case 1: Starting DTG + TAF/FTC is appropriate

. Pt Pt with early HIV, CD4=640, VL=31,000; genotype is pending.

  • Assuming resistance to 1 NRTI, should still be

effective

  • Data for DTG + 1 fully- active NRTI
  • Naives:
  • DTG + 3TC:
  • PADDLE, wk 48 VF in 1/20, no mutations
  • ACTG 5353: wk 24 VL <50 in 90%; 89% if BL VL

>100,000. VF with R in 1/120 (adherence issues)

  • Treatment-experienced:
  • DTG + 2NRTIs
  • SAILING: subset on DTG + 2 NRTIs with resistance to

1-2 NRTIs-> Wk 48 NO VF if 0 or 1 fully-active NRTI (0/13)

  • DAWNING: DTG + 2NRTIs (vs LPV/r + 2NRTIs) after VF

with 1st ART regimen->251 pts w/ 1 fully active NRTI, 84% w/ VL <50 at wk 48 (vs 73% of LPV/r); no IN or new RT mutations

Mean BL VL 4.21 log; >100K in 22%

Real-World Risk of Virologic Failure in Pts Starting DTG-Based vs DRV-Based ART

  • Patients who initiated DHHS

Recommended ART from 8/13- 3/17 at 8 CNICS sites (N = 5177)

  • 1229 on DTG or DRV/r with

ABC/3TC, TDF/FTC, or TAF/FTC

Nance R, et al. IDWeek 2017. Abstract 1688. Modified from clinicaloptions.com

†Virologic failure: HIV-1 RNA > 400 c/mL at ≥ 6 mos after initiating ART.

*Cox models adjusted for age, CD4+ cell count, days from last HIV-1 RNA, CNICS site, sex, HBV, HCV, HIV risk factor, and race.

Pts aHR* for VF† of DTG vs DRV (95% CI) All pts § DRV § DTG 0.41 (0.30-0.55) Tx-naive pts (1229) § DRV § DTG 0.32 (0.14-0.75)

  • DTG + TAF/FTC is a

potent, simple, tolerable regimen

  • Likelihood of

transmitted resistance is very low, and risk of VF from transmitted resistance is even lower,

  • esp. in next 2-3 weeks
  • Much clinical experience

from SFGH RAPID ART

Case 1: Counterpoint:

Brad Hare

No, not comfortable initiating TAF/FTC + dolutegravir… Would initiate another regimen

Buchacz (CROI 2013, #615). HOPS Cohort 1999-2011

  • Transmitted drug resistance still occurs

Case 1 (BH)

  • Transmitted drug resistance still
  • ccurs
  • Clinical trials:
  • Participants always have

baseline genotypes to enter

  • Reasonable clinical strategy:
  • Start broad (still simple), wait for

the data, and refine

  • What’s worse: 2-4 weeks of one

extra drug, or a lifetime of generated resistance?

Final Audience Vote

  • Given the many options for ART, would you

initiate TAF/FTC (Descovy) + dolutegravir (Tivicay)?

– (A) YES, I would TAF/FTC + DTG. – (B) NO, I would recommend something else.

Patient 2

  • 56 year old man, no medical co-morbidities
  • Diagnosed with HIV in 2012; initially started

TDF/FTC (Truvada) + ritonavir/darunavir and achieved virologic suppression.

  • Switched Truvada to TAF/FTC (Descovy) in 2016;

maintained RTV/DRV

  • Continuous virologic suppression

Audience Preliminary Vote

  • Would you recommend switching off the

protease inhibitor and switching to an integrase inhibitor? Or stay with current protease inhibitor?

– (A) I would switch the PI to an INSTI. – (B) I would continue the PI.

Case 2:

Annie Luetkemeyer

Would switch to integrase-based regimen

DHHS guidelines 10/17 https://aidsinfo.nih.gov/guidelines

NO Protease inhibitors in Preferred initial ART

Ryom L, et al. CROI 2017. Abstract 128LB.

PI’s associated with:

  • Increase CVD (53% increase in D:A:D

with DRV/r!)

  • Dyslipidemia
  • Metabolic derangement

AND NO current single pill formulation, to boot! NEAT-022: ≥ 50 yrs old or Framingham >10%,

  • n PI/r + NRTI, suppressed x ≥ 6 months, no

documented resistance/virologic failure

  • Non-inferior to PI/r
  • Improved lipid

profile

  • Improved

Framingham score (both ATZ and DRV)

Ryom L, et al. CROI 2017. Abstract 128LB.

Gatell TUAB1012 IAS 2017

Wha What if f pr preexi xisting ng resi sistanc nce? ?

  • SPIRAL study: 282 patients suppressed on PI/r x > 24

weeks, 40% with prior virologic failure

  • RAL-based regimen equivalent to PI/r, virologic failure rare (1
  • vs. 3)
  • DTG more potent than RAL
  • DTG/3TC dual therapy thus far effective in several pilot

switch studies and several pilot treatment initiation studies, thus:

üTAF should have efficacy with DTG even if M184 and 1-2 TAMs present üTransmitted INSTI resistance still very rare.

To Too soon for 2 drug therapy here!

  • The #1 goal for her is to maintain virologic suppression!
  • This patient would not have qualified for SWORD, PADDLE, NEAT

given her comorbidities

  • DTG + 2nd drug is one step away from DTG monotherapy
  • Excellent data to support 3 drug regimens, including NRTI-sparing
