The New Horizons (NH) Advancing Pediatric Care Collaborative was launched in 2014 by Janssen Pharmaceutical Companies of Johnson & Johnson (J&J), together with the Elizabeth Glaser Pediatric AIDS Foundation (EGPAF), national Ministries of Health (MOH) and other international, national and regional partners, NH was designed to support access to Darunavir and/or Etravirine donated by J&J as well as build healthcare capacity to manage pediatric treatment failure in children and adolescents. As 2024 is the 10th anniversary of NH, J&J and EGPAF want to celebrate and publicize the successes, lessons learned and tools developed through the collaborative. The satellite session will feature high-level speakers from J&J, EGPAF and other pediatric HIV stakeholders to highlight the need for a focus on treatment failure management in children and show data and success stories from NH that addresses these gaps.
