ART: Simplification/Switch Late Switch efficacy at 48 weeks Well tolerated. Why less AE than in W24??? No Virological Failures DTG-3TC-ABC good alternative for simplification Aboud et al. THAB02 STRIIVING: Switch to DTG-ABC-3TC from a variety of PI, INI or NNRTI Based Regimen

ART: Perspectives Argentina, Cahn et al. FRAB01 PADDLE: DTG-3TC in naïve patients (48w)
ART: Perspectives • CAB is an HIV-1 integrase inhibitor • Oral 30 mg tablet (t½, ~40 hours) • LA nanosuspension 200 mg/mL (t½, ~20-40 days) • RPV is an HIV-1 NNRTI • Oral 25 mg tablet (t½, ~50 hours) • LA nanosuspension 300 mg/mL (t½, ~30-90 days) • Oral 2-drug CAB + RPV proof of efficacy through Week 96 in LATTE-1 Margolis et al. THAB0206 LATTE‑2 (CAB-RIL) Week 48 Results
LATTE-2 Study Design Maintenance perioda Induction period CAB 400 mg IM + RPV 600 mg IM Q4W (n=115) CAB loading dose at Day 1 CAB 600 mg IM + RPV 900 mg IM Q8W (n=115) CAB 30 mg + ABC/3TC PO QD for 20 weeks (N=309) CAB 30 mg + ABC/3TC for 20 weeks CAB loading doses at Day 1 and Week 4 CAB 30 mg + ABC/3TC PO QD (n=56) Add RPV PO QD 4 weeks Week 96b Week 48 Analysis Dosing regimen confirmation Week 32 Primary analysis Dosing regimen selection Day 1 Randomization 2:2:1 Margolis et al.

Results: HIV-1 RNA <50 c/mL by Snapshot (ITT-ME) Maintenance period Induction period Proportion of patients with virological suppression, % W-4 W36 W44 W48 BL W-16 W-12 W-8 D1 W4 W8 W12 W16 W20 W24 W28 W32 W40 Study visit Oral CAB induction (ME population) Oral CAB (n=56) Q4W IM (n=115) Q8W IM (n=115) Margolis et al.

Snapshot Outcomes:HIV-1 RNA <50 c/mL at Week 48 (ITT-ME) aWeek 48 HIV-1 RNA Q8W: 50 c/mL, 57 c/mL, 97 c/mL, 110 c/mL, 135 c/mL, 463/205 c/mL; Q4W: 59 c/mL; Q8W: 5 of 6 remain in the study, 4 of 6 have HIV-1 RNA <50 c/mL at all subsequent visits through W80. bWithdrew consent: intolerability of injections. cQ4W: hepatitis C, rash, depression, psychosis, epilepsy, and Churg-Strauss vasculitis; oral CAB: hepatitis C, DILI. dQ8W: ISR; Q4W: pregnancy, prohibited medication, relocation; oral CAB: lost to follow-up, relocation, withdrew consent (wanted injections rather than oral tablets). Margolis et al. THAB0206
Conclusions • LATTE-2 results successfully demonstrate ability to maintain HIV-1 VL <50 c/mL with IM CAB + RPV LA, dosed every 4 or 8 weeks • Three subjects met PDVF criteria during maintenance • Q8W (n=2), oral CAB (n=1); one Q8W subject with emergent RPV and CAB resistance • Injection tolerability • Majority of ISRs were Grade 1 to 2 pain, with a median duration of 3 days • Few subjects had an ISR that led to discontinuation • High overall reported satisfaction • Dose selection • Q4W dosing resulted in lower rates of virologic non-response with similar safety to Q8W • Q4W dosing was selected for pivotal phase III studies

Co-infections • ASTRAL 5: SOF-VEL in HIV-HCV (pan-GTP)
Co-infections • ASTRAL 5: SOF-VEL in HIV-HCV (pan-GTP) Safe, well tolerated, no DDI
Co-infections • TURQUOISE-I, PART 2 : OMBITASVIR/PARITAPREVIR/RITONAVIR ± DASABUVIR WITH OR WITHOUT RIBAVIRIN IN PATIENTS WITH HIV-1 AND HCV GT1 OR GT4 CO-INFECTION
TURQUOISE-I Part 2 Study Design *Arm G was omitted from this analysis as the recommended regimen for GT1b patients is 3D without RBV = randomized treatment arms R
Efficacy: ITT & mITT Analyses by Genotype • 3 patients with GT1 infection did not achieve SVR12: • 1 on-treatment virologic failure • 2 relapses ART RESTRICTIONS *5 out of 200 patients have not yet reached the SVR12 time point and are excluded from the analysis mITT: modified ITT population, which excludes non-virologic failures and patients missing data ITT: intent-to-treat population
Co-infections • HIV-HBV: -3TC vs. 3TC-TDF for HBV MTCT -HCC in HIV-HBV at younger age than HIV (-) • HIV-TB, always present: Need to improve Diagnosis and Therapy (new drugs, new administration of old drugs) -RAFA trial: High R dose, reduce mortality

Take-Home Messages (for non-clinicians) Adolescents becoming a key population: special programs needed ART: strong differences in initial therapy North-South (InSTI) Dual therapies (Ex: DTG-3TC, DTG-RIL) may be a line to explore, even in experienced patients Long-lasting action injecting drugs? HCV-HIV do not seem longer a different population among HCV patients TB always there: need to improve D and T
Take-Home Messages (for non-clinicians) Non-AIDS conditions and aging, increasing problem in the North, emerging problem in the South Continue working to translate all this science into action… For EVERYONE
