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.

This is an open-label, non-randomized, Phase 1b/2 study to determine the safety and tolerability of NC410 when combined with a standard dose of Pembrolizumab. This study will also assess the clinical benefit of combination therapy in participants with advanced unresectable and/or metastatic ICI refractory solid tumors OR ICI naïve MSS/MSI-low solid tumors

This is an international, multicenter, open-label, randomized, Phase 3 study in patients with locally advanced, inoperable, or metastatic triple-negative breast cancer (mTNBC) who have not received previous therapy for advanced disease and whose tumors are PD-L1 positive (defined using the PD-L1 IHC 22C3 assay as tumors with a combined positive score [CPS] ≥ 10) at screening.

This phase II trial investigates the effect of combining two immune therapies, atezolizumab and CDX-1127 (varlilumab), with or without cobimetinib, in treating patients with biliary tract cancer that cannot be removed by surgery (unresectable).
