This randomized clinical trial studies how well an adaptive computerized cognitive training program works compared to a non-adaptive computerized cognitive training program in treating younger patients with brain tumor who underwent radiation therapy. Providing a computer training program may improve the well-being and quality of life of patients with cognitive (physical and mental) function difficulties caused by radiation therapy to the brain.

Single center, non-randomized, Phase 0 study. Sacituzumab Govitecan given preoperatively, followed by craniotomy with surgery or biopsy of brain tumors (GBM and metastatic brain tumors from Breast) and intraoperative tissue collection will follow with contemporaneous CSF (depending on tumor location) and whole blood (serum) sampling.

This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Radiotherapy uses high-energy radiation from x-rays to kill cancer cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, vincristine sulfate, cyclophosphamide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving reduced craniospinal radiation therapy and chemotherapy may kill tumor cells and may also reduce the late side effects of treatment.

This is an international, multicenter, open-label, randomized, Phase 3 study in patients withlocally advanced, inoperable or metastatic triple-negative breast cancer (TNBC) who have not received previous therapy for advanced disease and whose tumors are either: PD-L1 negative at screening (defined using the PD-L1 IHC 22C3 assay as tumors with a combined positive score (CPS) < 10), OR PD-L1 positive at screening (defined using the PD-L1 IHC 22C3 assay as tumors with a CPS ≥ 10) if they previously received a checkpoint inhibitor in the adjuvant or neoadjuvant setting.

This phase I trial studies the side effects and best dose of pembrolizumab and recombinant interleukin-12 in treating patients with solid tumors. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Recombinant interleukin-12 may kill tumor cells by blocking blood flow to the tumor and by stimulating white blood cells to kill tumor cells. Giving pembrolizumab and recombinant interleukin-12 may work better than giving pembrolizumab alone in treating patients with solid tumors.

This partially randomized phase III trial is studying maintenance chemotherapy to see how well it works compared to observation following induction chemotherapy and radiation therapy in treating young patients with newly diagnosed ependymoma. Drugs used in chemotherapy, such as vincristine sulfate, carboplatin, cyclophosphamide, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving chemotherapy with radiation therapy may kill more tumor cells and allow doctors to save the part of the body where the cancer started.
