NCT01004978
This randomized phase III trial studies chemoembolization and sorafenib tosylate to see how well they work compared with chemoembolization alone in treating patients with liver cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as doxorubicin hydrochloride, mitomycin, 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. Chemoembolization kills tumor cells by carrying drugs directly into blood vessels near the tumor and then blocking the blood flow to allow a higher concentration of the drug to reach the tumor for a longer period of time. Kinase inhibitors, such as sorafenib tosylate may stop the growth of tumor cells by blocking the action of an abnormal protein that signals cancer cells to multiply. It is not yet known whether giving chemoembolization together with sorafenib tosylate is more effective than chemoembolization alone in treating patients with liver cancer.

NCT05236712
This will be a pilot clinical trial to evaluate preliminary efficacy of a newly designed mobile intervention designed to support healthy eating in old people. The main scientific premise of this project is that mobile approaches are feasible for behavioral and metabolic improvements in the population of people 65+ with mild-to-moderate frailty. Specific Aim of this project is to describe feasibility, acceptability and initial efficacy of the newly designed mobile intervention in a pilot RCT. The pilot RCT, comparing usual care to usual care plus mobile intervention, will provide data on the sensitivity of outcome measures and estimated effect size to inform a larger RCT. Primary outcomes for the pilot RCT will include change in adherence to Mediterranean diet (MedD) score, change in insulin sensitivity measures, feasibility and acceptability. Secondary outcomes include MedD knowledge, self-efficacy, outcome expectation, self-regulation, social support, platform use and anthropometric and functional measures.
NCT03502577
This phase I trial determines the side effects and best dose of B-cell maturation antigen (BCMA)-chimeric antigen receptor (CAR) T-cells when combined with gamma-secretase inhibitor LY3039478 (JSMD194), cyclophosphamide, and fludarabine in treating participants with multiple myeloma that that has come back or remains despite treatment. Placing genes added in the laboratory into immune T-cells may make the T-cells recognize BCMA, a protein on the surface of cancer cells. JSMD194 may enhance the killing of cancer cells by increasing the BCMA expression on multiple myeloma cells, making the targeted BCMA CAR-T treatment more effective. JSMD194 also decreases the amount of BCMA found in the circulation (called soluble BCMA) that is not bound to the myeloma cells. JSMD194 can therefore reduce the potential for soluble BCMA to act as a decoy. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine, 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. Giving BCMA CAR T therapy with JSMD194, cyclophosphamide, and fludarabine may work better in treating participants with relapsed or persistent multiple myeloma.
NCT01940185

NCT04496219
This phase II trial studies the safety and feasibility of utilizing acupuncture in patients with high-risk bladder cancer that has not spread to the surrounding muscle (non-muscle invasive) undergoing treatment with Intravesical BCG. BCG is a weakened form of the bacterium Mycobacterium bovis that does not cause disease. It is used in a solution to stimulate the immune system in the treatment of bladder cancer. Unfortunately, many patients experience side effects such as pelvic pain, painful urination, severe urgency, frequency, urge incontinence, need to urinate at night, and/or infectious complications. These side effects may cause patients to delay or stop BCG treatment. Acupuncture is a medical intervention in which fine metallic needles are inserted into anatomical locations of the body to stimulate the peripheral and the central nervous system. Giving acupuncture before each intravesical BCG treatment may help to reduce the side effects of intravesical BCG, and help patients complete treatment. Specific outcomes of interest include acceptability to patients, effect of acupuncture on intravesical BCG-related side effects, and adverse events associated with acupuncture.
NCT04322708
This is a Phase 2/3, multi-center, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of lirentelimab (AK002) given monthly for 6 doses in adult and adolescent patients with active eosinophilic esophagitis. Subjects who complete the randomized, double-blind, placebo-controlled treatment may have the option to receive 6 doses of open-label lirentelimab (AK002) through the OLE Period of the study.
NCT03439462
A phase 1/2 multi-center investigation of nab-sirolimus (also known as ABI-009, nab-rapamycin) in combination with mFOLFOX6 and Bevacizumab as first-line therapy in patients with metastatic colorectal cancer
NCT03749460
This phase I/II trial studies the side effects and how well nivolumab and ipilimumab works when given together with stereotactic body radiation therapy (SBRT) in treating patients with salivary gland cancers. 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. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving nivolumab and ipilimumab and SBRT may work better in treating patients with advanced salivary gland cancers.

NCT05025852
The incidence of diabetes in pregnancy is rising, with rates of 1 in 7 pregnancies globally. Metformin is used for type 2 diabetes (T2DM) outside of pregnancy and is now increasingly prescribed during pregnancy. There are some concerns as metformin crosses the placenta and effects on offspring exposed during pregnancy are unknown. Animal and human evidence indicate that metformin may create an atypical in-utero environment similar to under-nutrition which has been associated with adult obesity. This is supported by studies in children of mothers treated with metformin in other populations where an increase in childhood obesity was found at 4-9 years of age. We now have evidence from the MiTy trial, that offspring of metformin-exposed women with T2DM have less large infants and are less adipose at birth, but are also more likely to be small for gestational age (SGA). These effects could lead to benefit or harm in the long-term. Offspring of MiTy mothers are currently being followed up to 2 years. Given that long-term effects may not be evident until 5 years of age, it is imperative to follow these children longer. Goals/Research Aims:To determine whether in-utero exposure to metformin, in offspring of women with T2DM, is beneficial or harmful in the long-term. Research Questions: 1. In offspring of women with T2DM, how does treatment with metformin during pregnancy affect a) adiposity b) growth over time c) metabolic syndrome d) cognitive and behavioral measures:2. What factors predict altered childhood adiposity and insulin resistance in these offspring? Primary Outcome: Body mass index (BMI) z-score. Secondary Outcomes: 1) other measures of adiposity (i.e. skinfolds, 2) growth over time 3) measures of insulin resistance 4) adipocytokines 5)neurodevelopment Expected Outcomes Given these increasing concerns, this study will inform the best treatment for pregnant mothers with diabetes by studying the long-term outcomes of children exposed to metformin during pregnancy.
