This phase II trial tests how well itacitinib works in in patients with immune related adverse events (irAEs) arising from immune checkpoint inhibitors (ICI) that do not respond to steroids (steroid refractory). Steroids are the usual treatment for these side effects. However, sometimes steroids do not improve or fix the side effects. Giving itacitinib may be effective in treating patients with known or suspected problems coming from ICIs, that do not resolve or improve with steroids, by reducing the patient's immune system response that can cause the irAEs.

This phase II trial tests how well decitabine and cedazuridine (DEC-C) works in combination with venetoclax in treating acute myeloid leukemia (AML) in patients whose AML has come back after a period of improvement (relapse) after a donor stem cell transplant. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving DEC-C in combination with venetoclax may kill more cancer cells in patients with relapsed AML.

This phase I/II trial studies the side effects, safety, and effectiveness of low dose radiation to the entire body (total body irradiation [TBI]) and higher dose radiation to known areas of cancer (hypofractionated radiation therapy [H-RT]) combined with atezolizumab and chemotherapy (carboplatin & etoposide) in treating patients with small cell lung cancer that has spread to disease sites outside of the lung (extensive stage). Extensive stage disease has historically been treated with chemotherapy alone with consideration of chest (thoracic) radiation therapy for those with response to chemotherapy, as well as consideration of preventative radiation therapy to the head (prophylactic cranial irradiation). Emerging evidence supports the synergistic interactions between immunotherapy and radiation therapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. Combining TBI and H-RT with atezolizumab and chemotherapy may improve response to treatment.

This phase I/II trial studies the side effects and best dose of a combination of gabapentin and ketamine and to see how well it works to prevent acute and chronic pain in patients receiving chemotherapy and radiation therapy (chemoradiation) for head and neck cancer that has spread to nearby tissue or lymph nodes (locally advanced). Gabapentin is a medication that is commonly used to treat nerve related pain. Specifically, it has been used to treat pain involving the mouth, throat and nasal passages in head and neck cancer patients treated with radiation. Ketamine is a type of general anesthetic that blocks pathways to the brain involved with sensing pain. This trial may help doctors determine how patients tolerate the combination of gabapentin and ketamine and to find the correct dosing for ketamine in those taking gabapentin. This will be the basis for a future, larger study to look at how effective this combination is at reducing and/or preventing pain in head and neck cancer patients.

This phase I/II trial tests the safety, side effects, and best dose of decitabine and cedazuridine (ASTX727) in combination with itacitinib and how well they work in treating patients with myelodysplastic/ myeloproliferative neoplasm. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Itacitinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving decitabine and cedazuridine in combination with itacitinib may work better in treating patients with myelodysplastic/myeloproliferative neoplasm.

This study will have two Phases: Phase 1a and Phase 1b. The goal of Phase 1a of this clinical
study is to learn more about the safety, tolerability and dosing of study drug KITE-197, in
participants with relapsed or refractory large B-cell lymphoma (r/rLBCL). The goal of Phase
1b of this clinical study is learn about the effectiveness of the recommended dose of
KITE-197 in participants with r/r LBCL.

The primary objectives of this study are:

Phase 1a: To evaluate the safety of KITE-197 in participants with r/r LBCL and determine the
target dose level for Phase 1b.

Phase 1b: To evaluate the efficacy of KITE-197 in participants with r/r LBCL as measured by
the complete remission (CR) rate.

This phase IV trial evaluates how well giving standard of care (SOC) peptide receptor radionuclide therapy (PRRT) after SOC surgical removal of as much tumor as possible (debulking surgery) works in treating patients with grade 1 or 2, somatostatin receptor (SSTR) positive, gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have spread from where they first started (primary site) to the liver (hepatic metastasis). Lutetium Lu 177 dotatate is a radioactive drug that uses targeted radiation to kill tumor cells. Lutetium Lu 177 dotatate includes a radioactive form (an isotope) of the element called lutetium. This radioactive isotope (Lu-177) is attached to a molecule called dotatate. On the surface of GEP-NET tumor cells, a receptor called a somatostatin receptor binds to dotatate. When this binding occurs, the lutetium Lu 177 dotatate drug then enters somatostatin receptor-positive tumor cells, and radiation emitted by Lu-177 helps kill the cells. Giving lutetium Lu 177 dotatate after surgical debulking may better treat patients with grade 1/2 GEP-NETs.

This phase II trial studies how well pembrolizumab after standard treatment with radiation plus the following chemotherapy drugs: cisplatin or carboplatin, plus etoposide works in treating patients with limited stage small cell lung cancer (LS-SCLC). 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. Giving pembrolizumab after standard treatment with radiation plus chemotherapy may increase the ability of the immune system to fight LS-SCLC.

This clinical trial evaluates different nerve patterns to the throat muscles (stylopharyngeus and pharyngeal constrictor) and what they look like in different patients by measuring and photographing them in the neck during surgery when the nerves are dissected (separated into pieces) as part of regular surgical care. Researchers think that some of the muscles in the neck might be useful for treating a condition called obstructive sleep apnea (OSA). This happens when muscles of the throat relax at night and the airway becomes blocked. Blockage of airflow leads to drops in oxygen levels and can disturb sleep by forcing a persons brain to wake to restore airway muscles so they can breathe. This trial may help researchers provide a new way to treat OSA that may be better than the current standard ones.

This clinical trial is studying how well magnetic resonance imaging (MRI) in combination with 18F-fluoromisonidazole (18F-FMISO) positron emission tomography (PET)/computed tomography (CT) scans works in assessing a decrease in the amount of oxygen (hypoxia) in tumor cells and in guiding adaptive radiation treatment in patients with head and neck cancer or cancer that has spread to the brain from where it first started (brain metastasis). Both head and neck cancer and brain metastases can be treated with radiation. Previous research studies have shown that the amount of oxygen that goes towards cancer cells prior to their radiation treatments predicts how the cancer cells will respond to radiation treatment. MRI is a type of imaging technique that uses radio waves and large magnets to produce detailed images of areas inside the body. 18F-FMISO is a radioactive substance that binds to hypoxic tumor cells and emits radiation, allowing the tumor cells to be visualized using PET/CT, which is an imaging technique that combines PET and CT in a single machine. It is used to make detailed, computerized images of inside the body. By combining MRI with 18F-FMISO PET/CT, researchers may be able to develop an MRI sequence that can be used to evaluate hypoxia in tumor cells and predict response to treatment in patients with head and neck cancer or brain metastases.
