The Platform invited the first 6 initial countries into  a two-day event held in Memphis, Tennessee on April 12 and 13, 2023. The Forum was designed to bring together partners representing a wide-range of experts and involved organizations in access to childhood cancer medicines from initial countries to work closely to define guideline principles and operational approach in preparation for a successful launch of the Platform. This Forum facilitated an exchange of best practices and strategies to address end-to-end needs relevant for childhood cancer medicines access, giving the opportunity for participants to co-design Platform processes to optimize implementation in the pilot phase and beyond.
