    Rilpivirine (RPV) is an NNRTI with the following attributes: • Anti-HIV-1 activity, EC50=0.3ng/mL1 • No teratogenicity in preclinical studies2

    • Half-life of ~ 50 hours3

    • Food increases RPV’s bioavailability by approximately 60% – RPV should be taken with a meal4

    • No significant drug interaction with TDF5 or FTC6

    • >99.7% protein-bound in vitro7

    • Metabolised primarily via the CYP3A pathway8

    • Eviplera (RPV + TDF/FTC) or Edurant (RPV)

    Taking RPV with food increases RPV exposure by 57% compared to fasting. RPV AUC was similar when administered after a high-fat or standard breakfast.

  • Drug Interactions: Contra-indications

    Drug that may decrease RPV plasma concentrations 1. Drugs that increase gastric pH

    – PPIs (esomeprazole, lansoprazole, omeprazole, pantoprazole, rabeprazole)

    Alternative #1: H2 blocker given at least 12h before or 4h after RPV Alternative #2: Antacids given ≥ 2h before or ≥ 4h after RPV

    2. CYP3A4 inducers – Anticonvulsants (carbamazepine, oxcarbazepine, phenobarbital,

    phenytoin) – Antimycobacterials (rifabutin, rifampin, rifapentine) – St. John’s Wort (Hypericum perforatum) – System glucocorticoid dexamethasone (more than a single dose)

    • Objectives: to assess the potential effects of oral RPV on embryo-foetal development in rats and rabbits

    • RPV did not show teratogenic potential in rat and rabbit models at exposures 13- to 80-times higher than those seen in HIV-1-infected patients receiving 25mg qd RPV at steady-state

    • These animal data suggest that further studies of RPV in women of child bearing potential are warranted

    † P

  • Pooled ECHO and THRIVE: Conclusions at Week 96

    • RPV showed sustained overall efficacy that was similar to EFV over 96 weeks (78% overall response in each group)

    – Suboptimal adherence was associated with reduced responses in both groups

    – Response was numerically higher in the RPV group with baseline VL ≤100K

    – The effect of suboptimal adherence and higher baseline viral load on VFeff was more apparent with RPV than with EFV

    • At Week 48 the overall VFres rate was higher with RPV than EFV, however, beyond Week 48 there were similar increases in VFres for both groups

    • RPV showed lower incidences than EFV of

    – Grade 2–4 overall AEs†

    – Dizziness, abnormal dreams/nightmares and rash (any grade)†

    – Discontinuations due to AEs (mainly rash and dizziness)

    – Grade 2 to 4 lipid abnormalities

    • From Week 48 to 96, there were no new safety concerns with either NNRTI

    • RPV was efficacious and well tolerated in a large and diverse group of treatment-naïve patients

    • RPV + TDF/FTC approved in Europe in naïve patients with

  • • Overall, RPV/TDF/FTC was non-inferior to EFV/FTC/TDF through 48 weeks for the primary endpoint of virologic suppression

    – Superior when baseline HIV-1 RNA ≤100,000 copies/mL – Non-inferior when baseline HIV-1 RNA >100,000 copies/mL

    • Overall, low and similar rates of virologic failure occurred for RPV/FTC/TDF (8%) and EFV/FTC/TDF (6%)

    – Similar rates observed for virologic failure with baseline HIV-1 RNA ≤100,000 c/mL (RPV/FTC/TDF 5%, EFV/FTC/TDF 3%) and for >100,000 to 500,000 c/mL (RPV/FTC/TDF 10%, EFV/FTC/TDF 9%); low rates of resistance

    – Higher rates of virologic failures for baseline HIV-1 RNA >500,000 c/mL (RPV/FTC/TDF 25%, EFV/FTC/TDF 16%); resistance rate higher for RPV/FTC/TDF (19% vs EFV/FTC/TDF 4%)

    • RPV/FTC/TDF is well-tolerated compared to EFV/FTC/TDF – Significantly fewer nervous system and rash adverse events – Significantly fewer discontinuations due to adverse events

    • Significant differences for change in lipids – TC, LDL, and TG favoring RPV/FTC/TDF – HDL favoring EFV/FTC/TDF – Similar change to TC:HDL ratio for both arms

  • 48

    • Through 24 weeks, switching to RPV/FTC/TDF was non-inferior to remaining on PI+RTV+2NRTIs (93.7% versus 89.9%) – In the delayed switch arm, virologic suppression was maintained through

    24 weeks with RPV/FTC/TDF (92.1%) – In the immediate switch arm, virologic suppression was maintained through

    48 weeks after switching to RPV/FTC/TDF (89.3%) • Lower rate of virologic failure observed in subjects switching to

    RPV/FTC/TDF (0.9%) compared to remaining on PI+RTV+2NRTIs (5.0%) at Week 24 – Low rate of virologic failure (1.3%) was also seen in the delayed

    switch arm – Through 48 weeks, RPV/FTC/TDF maintained a low rate (2.5%)

    of virologic failure • Resistance development was infrequent with switching to RPV/FTC/TDF • Switching to RPV/FTC/TDF resulted in improvement in fasting lipids,

  • BACKGROUND AND OBJECTIVES • Rilpivirine (RPV) is a second-generation NNRTI given once daily,

    available in France since September 2012. • In treatment-naïve patients, RPV has shown non-inferior antiviral

    activity versus efavirenz (EFV) in three large phase III clinical trials (ECHO, THRIVE and STAR).

    • The SPIRIT trial evaluated in virologically suppressed patients the switch from a boosted PI to RPV/TDF/FTC.

    • At week 48, among 317 patients who switched to RPV, 283 (89.3%) had VL< 50 cp/mL, 8 (2.5%) had VF and 8.2% had no data. 4/7 patients with VF developed RAM. (Pallela et al. AIDS 2014)

    • We wished to assess the efficacy and safety of RPV in treatment-experienced patients with suppressed HIV-1 replication switching to a RPV-based regimen in a “real-life” setting.

  • METHODS • Study design: observational, longitudinal, prospective, monocentric

    cohort study at Saint-Louis hospital (Paris-France) • Patients:

    – All antiretroviral therapy (ART) experienced HIV-1 infected patients switching to a RPV-based regimen

    – With a plasma HIV-RNA level 50 cp/mL and RPV discontinuation Window period M12 = M12+/- 8 weeks. A sensitivity analysis was performed with available data beyond M12. – Secondary endpoints: To describe:

    • Reasons for the switch • Virologic and immunological efficacy • Virologic failure and emergence of resistant associated mutation (RAM) • Clinical and biological tolerability.

  • 281 Patients included

    3491 Patients followed at Saint-Louis hospital

    385 Patients treated with RPV

    Exclusion of patients treated in trials: 9

    Exclusion of treatment-naive patients : 46

    Exclusion of patients without RPV: 7

    Exclusion of patients with VL> 50 cp/ml: : 42

    38 (14%) Patients discontinued RPV - 7 due to VF - 23 due to AEs - 6 due to other reasons - 2 patients died

    211 (75%) Patients remained on RPV at M12

  • Summary • RPV was overall well tolerated. Only 23 (8%) discontinued for AEs, 16 (70%) of whom with neuropsychiatric AEs.

    • 16 (6%) patients experienced virological failure, 5 (2%) of whom developed new NRTI or NNRTI RAMs. • RPV is indicated in France for naive patients with no baseline resistance and VL < 100,000 cp/ml and in well suppressed patients on a PI-based regimen with no previous failure or resistance • Patients with unknwon resistance genotype or a history of virological failure or with NNRTI and/or NRTIs (M184V) RAM should not be switched to RPV based regimen.
