Refractory Childhood Neuroblastoma

This phase I/II trial tests the safety, side effects, best dose and how well giving daraxonrasib works for the treatment of pediatric patients with solid tumors with RAS mutations that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Daraxonrasib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving daraxonrasib may be safe, tolerable and/or effective in treating patients with relapsed or refractory solid tumors with RAS mutations.
