All clinical trials

The trial proposed here attempts to reduce induction chemotherapy to phase I of standard induction in patients with B-precursor ALL. Induction phase II will be replaced by blinatumomab. The initial treatment phase is followed by sequential chemotherapy and further blinatumomab cycles.

Title: Impacts of mitochondrial-targeted antioxidant on leg blood flow and skeletal muscle mitochondrial function in peripheral artery disease patients. Peripheral artery disease (PAD) is a common cardiovascular disease, in which narrowed arteries reduce blood flow to the limbs, causing pain, immobility and in some cases amputation or death. PAD patients have shown higher levels of systemic and skeletal muscle inflammation due to the impaired oxygen transfer capacity of these blood vessels. This attenuated oxygen transfer capacity causes hypoxic conditions in the skeletal muscle and results in mitochondrial dysfunction and elevated reactive oxygen species (ROS). These harmful byproducts of cell metabolism are the major cause of intermittent claudication, defined as pain in the legs that results in significant functional limitations. One potential defensive mechanism to these negative consequences may be having higher antioxidant capacity, which would improve blood vessel vasodilatory function, enabling more blood to transfer to the skeletal muscles. Therefore, the purpose of this project is to examine the impact of mitochondrial targeted antioxidant (MitoQ) intake on oxygen transfer capacity of blood vessels, skeletal muscle mitochondrial function, leg function, and claudication in patients with PAD. Blood vessel oxygen transfer capacity in the leg will be assessed in the femoral and popliteal arteries. Skeletal muscle mitochondrial function and ROS levels will be analyzed in human skeletal muscle via near infrared spectroscopy and through blood samples. Leg function will be assessed by walking on a force platform embedded treadmill and claudication times will be assessed with the Gardner maximal walking distance treadmill test.

High-Flow Nasal Oxygen (HFNO) therapy has never been tested against Noninvasive ventilation, the reference standard therapy for acute exacerbation of chronic obstructive pulmonary disease (COPD), in randomized clinical trials. The aim of the present study is to compare the effects of HFNO therapy on arterial blood gas variables over the first 24 hours of therapy, to those of Noninvasive ventilation, in patients experiencing a moderate (i.e. with arterial pH within 7.25-7.35) exacerbation of COPD.

Nearly one third of patients with colorectal cancer develop liver metastases. It is well known that the achievement of a R0-situation is one of the most important factors for a positive long-term outcome. Despite further advantages in multimodal treatment concepts, only 20 - 30 % of the patients with metastases can be resected in curative intention. Recent studies, especially from Norway, have shown that liver transplantation might be a feasible option in well selected patients since the complete hepatectomy with subsequent liver transplantation can be an option for the achievement of a R0 situation. In this study, we pursue the strategy of two-stage hepatectomy combined with a left-lateral living donor liver transplantation. Inclusion criteria are as follows: non-resectable liver metastases of a primary colorectal carcinoma with an assumed portal-venous drainage of the tumor and at least a "stable disease" after a period of eight weeks systemic chemotherapy. Patients are excluded from the study if there is an extrahepatic tumor burden (with the exception of resectable lung metastases) or if the patient is not suitable for liver transplantation due to co-morbidities. The transplantation itself will be undertaken as a living donor liver transplantation where the left lateral liver lobe (liver segments 2 & 3) from a healthy volunteer donor will serve as graft. Prior transplantation, a left hemihepatectomy in the recipient is performed and the left lateral graft will be transplanted in this position. At the end of the transplantation procedure, the right portal vein will be closed to induce a rapid growth of the graft. The second step, and therefore the completion of the operation is performed after a growth period of the transplanted left-lateral lobe: in this procedure, the right hemi-liver of the recipient will be removed and the patient is supposed to be free of tumor at this point in time.

This randomized phase II trial studies how well chemotherapy before surgery and radiation therapy works compared to surgery and radiation therapy alone in treating patients with nasal and paranasal sinus cancer that can be removed by surgery. Drugs used in chemotherapy, such as docetaxel, cisplatin, and carboplatin 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 to kill tumor cells and shrink tumors. Giving chemotherapy before surgery and radiation therapy may make the tumor smaller and reduce the amount of normal tissue that needs to be removed and treated with radiation.

Background: Immunotherapy drugs help the body to fight cancer. Scientists think that combining some of these drugs will make them work better than when used alone. This may be true for many types of cancer, including castration-resistant prostate cancer (CRPC). Objective: To test if the combination of the drugs BN-brachyury, M7824, N-803, and Epacadostat is safe and shrinks tumors. Eligibility: People ages 18 and older with CRPC or another metastatic cancer Design: Participants will be screened with: Medical history Physical exam CT or MRI scans Possible bone imaging Blood, urine, and heart tests Possible tumor biopsy Participants will be treated with a 2-, 3- or 4-drug combinations of the following study drugs in 2-week cycles: Participants will receive M7824 by IV once every 2 weeks. Participants will receive N-803 by injection once every 2 weeks. They will record any skin changes at the injection site in a diary. Participants will receive BN-brachyury as 4 injections to different limbs. They will get the first 3 doses 2 weeks apart. Then they will get doses every 4 weeks for 6 months, then every 3 months for 2 years, then every 6 months. Participants will take Epacadostat orally every 12 hours. They will keep a pill diary. Participants will have physical exams and blood and urine tests at the start of each cycle. They may have scans every 12 weeks. Participants will continue treatment until their disease gets worse or they cannot tolerate the side effects. Participants will have a follow-up visit 4-5 weeks after they stop treatment. They will have a physical exam and blood tests. They may be asked to return for scans every 3 months.

The purpose of this study is to determine the safety of using an autologous mesenchymal stromal cell (MSC) coated fistula plug in people with fistulizing Crohn's disease. Autologous means these cells to coat the plug come from the patient.

The investigators hypothesize that palmar injections of botulinic toxin, via an inhibition of the sudation, would limit the occurrence of blisters in localized epidermolysis bullosa simplex (LEBS).

The purpose of this prospective, parallel-group, cohort study is to implement phenotype-guided targeted therapy based on functional signal transduction pathway (STP) activity in recurrent ovarian cancer patients using a novel mRNA-based assay. Existing targeted drugs with tolerable toxicity profiles are used to investigate the therapeutic value beyond their approved indication, which are deemed beneficial in the select group of patients with a relevant predominantly active functional STP, in order to improve survival and maintain quality of life.

The primary objective of this study is to describe the rate of local control in patients with her-2 positive early stage breast cancer with a complete response to chemotherapy and lumpectomy alone.
