This study is for children and young adults, aged 6 to 25, who have certain types of brain cancer that have not responded to other treatments. The study will test a new cancer treatment that combines two drugs, ibrutinib and indoximod, with chemotherapy. Ibrutinib helps block cancer cell growth, while indoximod boosts the immune system to fight cancer. This treatment is designed to work better against cancer than using just one drug alone.
- Study involves taking pills and requires the ability to swallow them.
