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

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

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

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.
