This phase II trial tests the safety, side effects, best dose and activity of tovorafenib (DAY101) in treating patients with Langerhans cell histiocytosis that is growing, spreading, or getting worse (progressive), has come back (relapsed) after previous treatment, or does not respond to therapy (refractory). Langerhans cell histiocytosis is a type of disease that occurs when the body makes too many immature Langerhans cells (a type of white blood cell). When these cells build up, they can form tumors in certain tissues and organs including bones, skin, lungs and pituitary gland and can damage them. This tumor is more common in children and young adults. DAY101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Using DAY101 may be effective in treating patients with relapsed or refractory Langerhans cell histiocytosis.

CB010A is a study evaluating safety, emerging efficacy, pharmacokinetics and immunogenicity
of CB-010 in adults with relapsed/refractory B cell non-Hodgkin lymphoma after
lymphodepletion consisting of cyclophosphamide and fludarabine.

This phase II/III trial tests the role of DNA released from tumor cells into the blood in guiding the use of immunotherapy (nivolumab alone or with relatlimab) after surgical removal of the bladder for bladder cancer treatment. DNA is material found inside all of our cells that acts as a blueprint for how cells function. Tumor cells often have abnormal DNA that looks different than DNA in normal cells. A new test called Signatera has been developed that can detect bladder cancer DNA in the blood which might indicate the presence of bladder tumor cells somewhere in the body. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Relatlimab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. This trial may help doctors determine if the Signatera test can better identify which patients need an additional treatment with immunotherapy to help prevent bladder cancer from coming back after surgery.

This phase II trial studies how well stopping anti-HER2 therapy works in improving outcomes of patients with HER2-positive breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and have experienced long-term benefit from first-line treatment (exceptional responders). Patients with metastatic HER2-positive breast cancer are currently treated with systemic drugs indefinitely. These drugs include chemotherapy and/or biological agents targeting the HER2 protein. The first drug combination administered after diagnosis of metastatic spread (i.e., first-line treatment) usually combines chemotherapy with anti-HER2 agents (trastuzumab with or without pertuzumab). Chemotherapy is administered for a limited number of months, and anti-HER2 agents are continued indefinitely as maintenance therapy. Some of these patients experience a long-term benefit from first-line treatment without cancer growth and can be defined as exceptional responders. Nevertheless, all patients with this type of tumor typically continue maintenance treatment with anti-HER2 therapy indefinitely. Exceptional responders usually receive treatment for many years. Information learned from this trial may help researchers understand whether maintenance anti-HER2 treatment can be safely stopped in patients with exceptional response to first-line therapy.

This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and may reduce harm to normal cells. Lutetium Lu 177 dotatate may be more effective than everolimus in shrinking or stabilizing advanced bronchial neuroendocrine tumors.

This phase II trial studies how well TPIV100 and sargramostim work in treating patients with HER2 positive, stage I-III breast cancer that has residual disease after chemotherapy prior to surgery. It also studies why some HER2 positive breast cancer patients respond better to chemotherapy in combination with trastuzumab and pertuzumab. TPIV100 is a type of vaccine made from HER2 peptide that may help the body build an effective immune response to kill tumor cells that express HER2. Sargramostim increases the number of white blood cells in the body following chemotherapy for certain types of cancer and is used to alert the immune system. It is not yet known if TPIV100 and sargramostim will work better in treating patients with HER2 positive, stage I-III breast cancer.

This phase III trial compares the addition of total ablative therapy to the usual systemic therapy versus the usual systemic therapy alone in treating patients with advanced colorectal cancer that has spread to up to 4 body sites (limited metastatic). The usual approach for patients who are not participating in a study is treatment with intravenous (through a vein) and/or oral medications (systemic therapy) to help stop the cancer sites from getting larger and the spread of the cancer to additional body sites. The ablative local therapy will consist of very focused, intensive radiotherapy called stereotactic ablative radiotherapy (SABR) with or without surgical resection and/or microwave ablation, which is a procedure where a needle is temporarily inserted in the tumor and heat is used to destroy the cancer cells. The addition of ablative local therapy to the usual approach of systemic therapy could be more effective than usual chemotherapy alone by increasing the life of patients with limited metastatic colorectal cancer.

This phase II trial studies the best approach to combine chemotherapy and radiation therapy (RT) based on the patients response to induction chemotherapy in patients with non-germinomatous germ cell tumors (NGGCT) that have not spread to other parts of the brain or body (localized). This study has 2 goals: 1) optimizing radiation for patients who respond well to induction chemotherapy to diminish spinal cord relapses, 2) utilizing higher dose chemotherapy followed by conventional RT in patients who did not respond to induction chemotherapy. Chemotherapy drugs, such as carboplatin, etoposide, ifosfamide, and thiotepa, 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. Radiation therapy uses high energy x-rays or high-energy protons to kill tumor cells and shrink tumors. Studies have shown that patients with newly-diagnosed localized NGGCT, whose disease responds well to chemotherapy before receiving radiation therapy, are more likely to be free of the disease for a longer time than are patients for whom the chemotherapy does not efficiently eliminate or reduce the size of the tumor. The purpose of this study is to see how well the tumors respond to induction chemotherapy to decide what treatment to give next. Some patients will be given RT to the spine and a portion of the brain. Others will be given high dose chemotherapy and a stem cell transplant before RT to the whole brain and spine. Giving treatment based on the response to induction chemotherapy may lower the side effects of radiation in some patients and adjust the therapy to a more efficient one for other patients with localized NGGCT.

This phase III trial studies if selumetinib works just as well as the standard treatment with carboplatin/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low-grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, 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. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine.

This phase II trial studies how well cabozantinib works in combination with nivolumab and ipilimumab in treating patients with rare genitourinary (GU) tumors that that has spread from where it first started (primary site) to other places in the body. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib, nivolumab, and ipilimumab may work better in treating patients with genitourinary tumors that have no treatment options compared to giving cabozantinib, nivolumab, or ipilimumab alone.
