There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The study will compare the effectiveness of amitriptyline versus placebo (inactive medication) in treating chronic laryngitis. At the baseline visit, subjects will be assigned at random to amitriptyline or placebo which they will take for 8 weeks. Subjects will be seen in the clinic at baseline and at 8 weeks. Improvement will be measured using standardized symptom scales, and a self-reported subjective improvement percentage.
This phase I/II trial studies the safety of topical phenylephrine solution and to see how well it works in preventing oral mucosa (mouth sores) in bone marrow transplant patients receiving cyclophosphamide and total body radiation therapy. Topical phenylephrine solution may prevent or lessen the severity of oral mucosa in patients receiving cyclophosphamide and total body radiation prior to undergoing a bone marrow transplant.
1. To determine if a formula derived from PCA using specific patient parameters can be used to determine the individual contrast material dose and provide a more consistent level of vascular and parenchymal enhancement during MDCT scanning of the abdomen and pelvis. 2. Up to 500 adult patients referred for a "CT of the abdomen and pelvis with contrast material" will be recruited to participate in this trial. Single CT axial slices (n=2) will be obtained at the level of the L4 pedicle and the supra-acetabular pelvis using a field-of-view that includes all of the patient. From patient measurements (height, weight, body dimensions), a customized dose of contrast material will be specified according to the derived formula for 400 subjects. One hundred subjects will receive the usual fixed contrast dose. 3. Enhancement data in HU will be measured from the CT scans using manually-placed ROIs on the upper abdominal aorta, main portal vein and liver parenchyma, avoiding visible liver tumors, major blood vessels and artifacts, if present. This enhancement data will be used to determine the patient-to-patient variability.
This study is intended to measure declarative or stored memory and behavior between infants who consume one of two infant formulas through approximately one year of age.
Allogeneic transplant can sometimes be an effective treatment for leukemia. In a traditional allogeneic transplant, patients receive very high doses of chemotherapy and/or radiation therapy, followed by an infusion of their donor's bone marrow or blood stem cells. The high-dose chemotherapy drugs and radiation are given to remove the leukemia cells in the body. The infusion of the donor's bone marrow or blood stem cells is given to replace the diseased bone marrow destroyed by the chemotherapy and/or radiation therapy. However, there are risks associated with allogeneic transplant. Many people have life-threatening or even fatal complications, like severe infections and a condition called graft-versus-host disease, which is caused when cells from the donor attack the normal tissue of the transplant patient. Recently, several hospitals around the world have been using a different type of allogeneic transplant called a microtransplant. In this type of transplant, the donor is usually a family member who is not an exact match. In a microtransplant, leukemia patients get lower doses of chemotherapy than are used in traditional allogeneic transplants. The chemotherapy is followed by an infusion of their donor's peripheral blood stem cells. The objective of the microtransplant is to suppress the bone marrow by giving just enough chemotherapy to allow the donor cells to temporarily engraft (implant), but only at very low levels. The hope is that the donor cells will cause the body to mount an immunologic attack against the leukemia, generating a response called the "graft-versus-leukemia" effect or "graft-versus-cancer" effect, without causing the potentially serious complication of graft-versus-host disease. With this research study, the investigators hope to find out whether or not microtransplantation will be a safe and effective treatment for children, adolescents and young adults with relapsed or refractory hematologic malignancies
The goal of this protocol is to evaluate the potential of PET imaging of amino acid transport and microglial activation to improve the differentiation of tumor recurrence and radiation necrosis in patients with brain metastases after treatment with stereotactic radiosurgery (SRS) who have re-growing lesions. These state-of-the-art imaging tools will be used in combination with standard magnetic resonance imaging (MRI), MR spectroscopy (MRS) and FDG-PET (fluorodeoxyglucose).
This is an open label extension study in subjects with Sickle Cell Disease (SCD) who have completed the double blind Phase 3 study (B5201002).
SPECIFIC STUDY AIMS 1. To evaluate congruence between pelvic anatomical structures segmented on MRI and/or CT scans co-registered with transperineal US scans acquired with an optically and/or electromagnetically tracked matrix array ultrasound transducer. 2. To estimate the achievable accuracy of anatomy tracking based on 3D US matrix-array transducer imaging and grey-level based image registration algorithms.
This was an open-label, single-arm, Phase II study in which amcasertib (BBI503) was administered to adult, asymptomatic patients with recurrent ovarian cancer who had elevated CA-125.
Acne vulgaris is a multifactorial, highly prevalent dermatologic condition that results in visible lesions that can be quite disfiguring. Consequently, individuals with acne often suffer from a wide range of psychological manifestations. Although there is consensus that combination therapy is most effective in treating acne, researchers are constantly striving to develop new treatment. Microcurrent therapy (MCT) is a non-invasive modality that has successfully been used to promote wound healing and has been routinely used in aesthetics. Use of MCT alone or in combination with current successful treatment such as blue light phototherapy (BLP), may hold promise for acne treatment. The investigators propose to conduct a small randomized control trial to determine the safety and preliminary efficacy of a novel combination therapy to treat acne vulgaris. The investigators will recruit up to 60 males and females and randomly assign them to one of 3 arms: 1) BLP; 2) MCT; and combination therapy (BLP and MCT). The investigators will assess physiological parameters (number of acne lesions, amount of sebum produced, degree of acne severity) and psychosocial factors (dermatologic quality of life, social anxiety, depressive symptomatology, self-esteem). Participants will complete a baseline assessment prior to initiating treatment and a follow-up assessment at 4 weeks post termination of treatment. The investigators will conduct intermediary assessments at weeks 3 and 5 and 1 week post termination of the treatment. The investigators will use measures of central tendency to describe the sample and repeated measures analysis of variance to compute the main and interaction effects.
