Summary
Phase 1: - To confirm the safety and anticipated recommended phase 2 dose (RP2D) of REGN2810 (cemiplimab) for children with recurrent or refractory solid or Central Nervous System (CNS) tumors - To characterize the pharmacokinetics (PK) of REGN2810 given in children with recurrent or refractory solid or CNS tumors Phase 2 (Efficacy Phase): - To confirm the safety and anticipated RP2D of REGN2810 to be given concomitantly with conventionally fractionated or hypofractionated radiation among patients with newly diagnosed diffuse intrinsic pontine glioma (DIPG) - To confirm the safety and anticipated RP2D of REGN2810 given concomitantly with conventionally fractionated or hypofractionated radiation among patients with newly diagnosed high-grade glioma (HGG) - To confirm the safety and anticipated RP2D of REGN2810 given concomitantly with re-irradiation in patients with recurrent HGG - To assess PK of REGN2810 in pediatric patients with newly diagnosed DIPG, newly diagnosed HGG, or recurrent HGG when given in combination with radiation - To assess anti-tumor activity of REGN2810 in combination with radiation in improving overall survival at 12 months (OS12) among patients with newly diagnosed DIPG - To assess anti-tumor activity of REGN2810 in combination with radiation in improving progression-free survival at 12 months (PFS12) among patients with newly diagnosed HGG - To assess anti-tumor activity of REGN2810 in combination with radiation in improving overall survival at OS12 among patients with recurrent HGGPhase:
