Agenda • Introduction- Jessica Rodrigues, IATT • Paediatric Treatment Optimization- George Silberry, Senior Technical Advisor for Pediatric HIV, OGAC • Optimal regimen selection and sequencing- Elaine Abrams Senior Director for Research, ICAP • Optimal formulation selection- Marc Lallemant Head of Pediatric HIV, DNDi and Janice Lee Project Manager for Pediatric HIV, DNDi • Optimizing supply chain management- Nandita Sugandhi, Senior Clinical Advisor, CHAI and Marianne Gauval Associate Director of Pediatric Access, CHAI • Q&A/Discussion- Surbhi Modi, Maternal and Infant HIV Team Lead, CDC 2013 WHO Recommendations First-line Antiretroviral Regimens Children < 3 years Children 3 years to < 10 years Adolescents > 10 years Preferred ABC + 3TC + LPV/r or AZT + 3TC + LPV/r ABC + 3TC + EFV TDF + 3TC + EFV Alternative ABC + 3TC + NVP AZT + 3TC + NVP ABC + 3TC + NVP AZT + 3TC + EFV AZT + 3TC + NVP TDF + 3TC (or FTC) + EFV TDF + 3TC (or FTC) + NVP AZT + 3TC + EFV AZT + 3TC + NVP TDF + 3TC (or FTC) + NVP At program level generally fewer choices are available: •Simplifies guidance for health care workers •Streamlines procurement and supply chain Choosing a Preferred Pediatric First Line Children < 3 years • • • • • Effective Preferred ABC + 3TC + LPV/r Safe Or Forgiving AZT + 3TC + LPV/r Easy to take Easy transition as children grow Children 3 years to < 10 years Adolescents > 10 years ABC + 3TC + EFV TDF + 3TC + EFV Life-long Treatment: Rational Sequencing of Regimens Starting in Childhood • Objective to achieve simplified recommendations harmonized across all age groups • Rational sequencing of drugs and drug regimens for a public health approach • From first to second to third line • From infancy to adulthood • Considerations for guidance for regimen transitions as children age into adulthood frRational SequencingofofNRTI’s NRTI’s Rational sequencing AZT Thymidine Analogs d4T ABC Cytidine Analogs TDF Thymidine analogs may be MORE effective after failure on cytidine analogs; cytidine analogs may be LESS potent after thymidine analog failure and accumulation of TAMS 5 First-line Determines Second-line WHO, 2013 Simplifying Second-line ART Challenge Solution Low recognition of treatment failure Expanded use of VL for routine monitoring Currently used 2nd line regimens don’t support adherence Simpler options are available (e.g. ATV/r for older children) Confusion about what to Introduction of new use after LPV/r failure in 1st agents: Raltegravir line >4weeks, dolutegravir >12 yrs, darunavir for >3 years Raltegravir • Dosing established in pediatrics for ≥ 4 weeks of age • Pediatric formulations available: – Powder for suspension for <10kg – Chewable tab for >10kg • Twice daily dosing • RTG dosing with TB co-treatment under study • Currently limited availability • Limited interest for adults Good option but not favourable for harmonization Dolutegravir • Low dose/kg is good for infants and children • High genetic barrier ideal for poorly adherent children and adolescents • Once daily dosing and good toxicity profile • Only approved for ≥12 years of age • Dispersible formulation in development • Not FDC ready yet and only planned in combination with abacavir • Ongoing and planned studies for children IMPAACT 1093 & ODYSSEY Ideal for harmonization but not yet a reality : Third-line forChildren: Children: Third-line ART ART for a PublicHealth Health Approach Approach Possible? Is Is a Public Possible? Challenge Solution Individualized regimens based on resistance pattern New guidance from WHO based on rational sequencing and availability of new drugs Cost Availability in RLS Affordable options should become available with increasing demand Programs are beginning to plan for introduction of third-line (New Horizons) 10
