NCT05987241
This phase II/III trial examines whether patients who have undergone surgical removal of bladder, kidney, ureter or urethra, but require an additional treatment called immunotherapy to help prevent their urinary tract (urothelial) cancer from coming back, can be identified by a blood test. Many types of tumors tend to lose cells or release different types of cellular products including their DNA which is referred to as circulating tumor DNA (ctDNA) into the bloodstream before changes can be seen on scans. Health care providers can measure the level of ctDNA in blood or other bodily fluids to determine which patients are at higher risk for disease progression or relapse. In this study, a blood test is used to measure ctDNA and see if there is still cancer somewhere in the body after surgery and if giving a treatment will help eliminate the cancer. Immunotherapy with monoclonal antibodies, such as nivolumab and relatlimab, can help the body's immune system to attack the cancer, and can interfere with the ability of tumor cells to grow and spread. This trial may help doctors determine if ctDNA measurement in blood can better identify patients that need additional treatment, if treatment with nivolumab prolongs patients' life and whether the additional immunotherapy treatment with relatlimab extends time without disease progression or prolongs life of urothelial cancer patients who have undergone surgical removal of their bladder, kidney, ureter or urethra.
NCT03698019
This phase II trial studies how pembrolizumab works before and after surgery in treating patients with stage III-IV high-risk melanoma. 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 before and after surgery may work better compared to after surgery alone in treating melanoma.
NCT03375307
This phase II trial studies how well olaparib works in treating patients with bladder cancer and other genitourinary tumors with deoxyribonucleic acid (DNA)-repair defects that has spread to other places in the body (advanced or metastatic) and usually cannot be cured or controlled with treatment. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing.
NCT04691154
This Phase 3, 2-part, open-label, multicenter study aims to demonstrate the safety and tolerability of L606 in patients with PAH or PH-ILD. The study will determine the short-term and long-term safety and tolerability of L606 in this patient population.
NCT06179888
This phase II trial compares iberdomide maintenance therapy to disease monitoring for improving survival in patients who have received idecabtagene vicleucel (a type of chimeric antigen receptor T-cell \[CAR-T\] therapy) for multiple myeloma. The usual approach after treatment with idecabtagene vicleucel is to monitor the multiple myeloma without giving myeloma medications. There is currently no medication approved specifically for use after idecabtagene vicleucel treatment. Upon administration, iberdomide modifies the immune system and activates immune cells called T-cells, which could enhance the effectiveness of idecabtagene vicleucel. Iberdomide may keep multiple myeloma under control for longer than the usual approach (disease monitoring) after idecabtagene vicleucel, and may help multiple myeloma patients live longer.
NCT03914625
This phase III trial studies how well blinatumomab works in combination with chemotherapy in treating patients with newly diagnosed, standard risk B-lymphoblastic leukemia or B-lymphoblastic lymphoma with or without Down syndrome. Monoclonal antibodies, such as blinatumomab, may induce changes in the body's immune system and may interfere with the ability of cancer cells to grow and spread. Chemotherapy drugs, such as vincristine, dexamethasone, prednisone, prednisolone, pegaspargase, methotrexate, cytarabine, mercaptopurine, doxorubicin, cyclophosphamide, and thioguanine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Leucovorin decreases the toxic effects of methotrexate. Giving monoclonal antibody therapy with chemotherapy may kill more cancer cells. Giving blinatumomab and combination chemotherapy may work better than combination chemotherapy alone in treating patients with B-ALL. This trial also assigns patients into different chemotherapy treatment regimens based on risk (the chance of cancer returning after treatment). Treating patients with chemotherapy based on risk may help doctors decide which patients can best benefit from which chemotherapy treatment regimens.
NCT05279053
The proposed study evaluated sex differences in glutamate (Glu), with a focus on the dorsal anterior cingulate cortex (dACC), anterior insula, and thalamus, as well as how it is influenced by sex (males vs. females), smoking state (overnight abstinent vs. sated), and circulating ovarian hormones (estrogen and progesterone) in women. Glu was measured in the entire brain with special focus on the dorsal anterior cingulate cortex (dACC), anterior insula, and thalamus, all of which have been implicated in tobacco withdrawal, using an echo-planar spectroscopic imaging (EPSI) variant of magnetic resonance spectroscopy (MRS). Serum ovarian hormones (estrogen and progesterone) were measured for female participants to determine relationships between brain Glu and this hormone. Glu was be measured in smokers after overnight (\~12 h) abstinence and after participants smoked the first cigarette of the day.
NCT02775851
This pilot phase II trial studies how well pembrolizumab works in treating patients with desmoplastic melanoma (DM) that can be removed by surgery (resectable) or cannot be removed by surgery (unresectable). 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.
NCT03233711
This phase III trial investigates how well nivolumab after combined modality therapy works in treating patients with high risk stage II-IIIB anal cancer. 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.
NCT04310007
This phase II trial compares cabozantinib alone and the combination of cabozantinib and nivolumab to standard chemotherapy in the treatment of patients with non-squamous non-small cell lung cancer (NSCLC). 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, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ramucirumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as docetaxel, gemcitabine hydrochloride, paclitaxel, and nab-paclitaxel, 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 cabozantinib alone or in combination with nivolumab may be more effective than standard chemotherapy in treating patients with non-small cell lung cancer.
NCT04068194
This phase I/II trial studies the best dose and side effects of peposertib and to see how well it works with avelumab and hypofractionated radiation therapy in treating patients with solid tumors and hepatobiliary malignancies that have spread to other places in the body (advanced/metastatic). Peposertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving peposertib in combination with avelumab and hypofractionated radiation therapy may work better than other standard chemotherapy, hormonal, targeted, or immunotherapy medicines available in treating patients with solid tumors and hepatobiliary malignancies.
NCT04595747
This phase II trial studies the effect of rogaratinib in treating patients with sarcoma with a change in a group of proteins called fibroblast growth factor receptors (FGFRs) or SDH-deficient gastrointestinal stromal tumor (GIST). Rogaratinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
NCT06311227
This phase II trial tests how well venetoclax works in treating patients with hairy cell leukemia that has come back after a period of improvement (relapsed). 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.
NCT07219173
The purpose of this study is to assess the safety and efficacy of brenipatide at different dose levels compared with placebo in participants with moderate-to-severe asthma. Study participation will last approximately 65 weeks, including screening, treatment, and follow-up periods.
NCT07169851
The purpose of this study is to check how well LY35327021 works and how safe it is for controlling nausea and vomiting caused by chemotherapy. Participants who join this study will be in it until all parts are finished, which could take about 2 months.
NCT05673200
This phase I trial tests the safety, side effects, and best dose of ASTX727 when given in combination with a usual approach of treatment with paclitaxel and pembrolizumab in patients with triple-negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). The usual approach is defined as care most people get for this type of cancer. The usual approach for patients with metastatic triple negative breast cancer who are not in a study is chemotherapy with drugs like paclitaxel, carboplatin, cisplatin, eribulin, vinorelbine, capecitabine, gemcitabine, doxorubicin or cyclophosphamide. There is a protein called PD-L1 that helps regulate the body's immune system. For patients who have PD-L1+ tumors, immunotherapy (pembrolizumab) is usually added to paclitaxel or carboplatin/gemcitabine as initial treatment. For patients who have PD-L1-negative tumors, chemotherapy alone is used, without immunotherapy. ASTX727 is a combination of two drugs, decitabine and cedazuridine. 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. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. 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 ASTX727 with usual treatment approach with paclitaxel and pembrolizumab may be able to shrink or stabilize the tumor for longer than the usual approach alone in patients with metastatic triple negative breast cancer.
NCT06980038
This phase II trial compares the effectiveness of cemiplimab with CDX-1140 to cemiplimab without CDX-1140 prior to surgery in treating patients with stage III-IV head and neck cancer. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. CDX-1140 is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Giving cemiplimab with CDX-1140 versus cemiplimab alone before surgery may make the tumor smaller and may reduce the amount of normal tissue that needs to be removed for patients with stage III-IV head and neck cancer.
NCT07115329
The goal of this clinical trial is to learn if zelquistinel works to treat depression in adults. It will also learn about the safety of zelquistinel. The main questions it aims to answer are: Does zelquistinel reduce depression scores in participants compared to participants who take a placebo (a look-alike tablet that contains no zelquistinel1)? What medical problems are observed in participants who take zelquistinel? Participants will take one tablet of zelquistinel or placebo every week for 6 weeks. Participants will visit the clinic every week of the 6 week period to have the severity of their depression evaluated.
