NCT01838876
The objective of this study is to evaluate the long-term safety and tolerability of cariprazine as an adjunctive treatment to antidepressant therapy (ADT) in patients with Major Depressive Disorder (MDD).
NCT03397186
This research trial studies the immune changes following trabectedin in patients with sarcoma that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Analyzing tumor tissue may help to understand the changes in immune cells in or around the tumor or if there is an increase in immune cells in the tumor after receiving trabectedin.
NCT00005799
This clinical trial studies fludarabine phosphate, low-dose total body irradiation, and donor stem cell transplant in treating patients with hematologic malignancies or kidney cancer. Giving chemotherapy drugs, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine before the transplant and cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.
NCT01282463
This multicenter trial will enroll participants with metastatic transitional cell carcinoma of the bladder, urethra, ureter, or renal pelvis who have had disease progression on first-line platinum-based chemotherapy regimens. Participants will be enrolled into 1 of 3 treatment arms: docetaxel; docetaxel and ramucirumab; or docetaxel and icrucumab.
NCT01768650
This study seeks to compare two different behavioral treatments for pain in Veterans with a history of TBI. Both treatments involve educating the Veteran about pain, discussing the impact of pain, and different ways to manage it in hopes of decreasing pain and its impact on life. These approaches are called "self-management" approaches to pain. Both of these treatments are commonly used in pain clinics to treat pain in persons with back pain, headaches, and other types of chronic pain. The investigators will be delivering both treatments over the telephone to make the treatments accessible to Veterans wherever they live.
NCT02710318
Immunization is one of the most effective public health interventions. Yet, nationally coverage has consistently fallen short of national goals, and has remained for the most part stagnant. The continued presence of vaccine-preventable diseases poses a threat to public health. In addition to needed improvement of immunization coverage for the general pediatric/adolescent population, some children with chronic medical conditions need specific additional immunizations, yet many fail to receive them. Immunization reminders for providers in the electronic health record (EHR) are a type of clinical decision support (CDS) that can reduce missed immunization opportunities. One limitation of these reminders is that they generally depend only on data local to the EHR, which can be incomplete due to record scatter, leading to inaccurate alerts. An Immunization Information System (IIS), also known as an immunization registry, is a population-based system that collects immunization data primarily for children and adolescents from providers at a regional or state level. The investigators seek to couple bidirectional exchange of IIS immunization information and forecasting tools with patient level medical history from the EHR to deliver accurate, patient-specific EHR immunization reminders.
NCT01287585
This is a study of ADI-PEG 20 (pegylated arginine deiminase), an arginine degrading enzyme versus placebo in patients with hepatocellular carcinoma who have failed prior systemic treatment (chemotherapy). Hepatocellular carcinomas have been found to require arginine, an amino acid. Thus the hypothesis is that by restricting arginine with ADI-PEG 20, the hepatocellular carcinoma cells will starve and die.
NCT00621309
Adverse drug-drug interactions (DDIs) are responsible for approximately 3% of all hospitalizations in the US, perhaps costing more than $1.3 billion per year. One of the most common causes of DDIs is the when one drug alters the metabolism of another. A key enzyme in the liver and intestine, called "cytochrome P450 3A4 (CYP3A4) is generally considered to be the most important drug metabolizing enzyme. The gene for CYP3A4 can be 'turned on' by the presence of certain other drugs, resulting in much higher levels of CYP3A4 in the liver and intestine. Thus, when a drug that induces CYP3A4 is given with or before another drug that is metabolized by 3A4, a 'drug-drug' interaction occurs because the first drug (the inducer) greatly changes the rate at which the second drug (CYP3A4 substrate) is removed from the body. Many drugs increase CYP3A4 activity by binding to a receptor called the Pregnane-X-Receptor (PXR), which is a major switch that controls the expression of the CYP3A4 gene. Using human liver cells we have demonstrated that sulforaphane (SFN), found in broccoli, can block drugs from activating the PXR receptor, thereby inhibiting the switch that causes CYP3A4 induction. The purpose of this project is to determine if SFN can be used to block adverse DDIs that occur when drugs bind to and activate the PXR receptor and subsequently induce CYP3A4 activity. We will recruit 24 human volunteers to participate in the study. This project will determine whether SFN can prevent the drug Rifampin from binding to PXR and increasing CYP3A4 activity in humans following oral administration of SFN (broccoli sprout extract). The rate of removal of a small dose of the drug midazolam will be used to determine the enzymatic activity of CYP3A4 before and following treatment with Rifampin, in the presence or absence of SFN, since midazolam is only eliminated from the bloodstream by CYP3A4. . We predict that SFN will prevent the increase in midazolam clearance (metabolism) that normally follows treatment with the antibiotic, rifampicin. This research is important because it could potentially lead to a simple, cost-effective way of preventing one of the most common causes of adverse drug-drug interactions that occurs today. For example, rifampicin, which is a cheap and effective antibiotic used to treat TB, cannot be used in HIV/AIDS patients because it increases the metabolism of many of the antiretroviral drugs used to treat HIV/AIDS. TB is a major opportunistic infection in AIDS patients, so this is a serious clinical problem, especially in developing countries where more expensive alternative drug therapies are not available. We hypothesize that co-formulation of rifampicin with SFN could block this drug-drug interaction without altering its efficacy, thereby allowing its use in HIV/AIDS patients infected with TB. This is but one example of numerous drug-drug interactions that occur via this mechanism.
NCT02239120
This trial will enroll approximately 6,000 patients with recent embolic stroke of unknown source (ESUS). Patients will be randomized to dabigatran or acetylsalicyclic acid (ASA) (1:1 ratio) and have visits every three months. The study doctor may prescribe blinded concomitant ASA for pts with coronary artery disease but this is not mandatory. All Adverse Events (AEs), Serious Adverse Events (SAEs), outcome events will be recorded. The trial will conclude when the required number of stroke events are positively adjudicated which is estimated to take 3 years (including 2.5 years of enrollment).
NCT01182350
Diagnosis of diffuse intrinsic pontine glioma (DIPG) for decades has relied on imaging studies and clinical findings. Histologic confirmation has been absent with surgical biopsy of brainstem tumors not believed to have acceptable safety. The prognosis of DIPG has remained quite poor and novel therapeutic strategies are needed. This DIPG Biology and Treatment Study (DIPG-BATS) study incorporates a surgical biopsy at presentation using strict preoperative neurosurgical planning and stratifies participants to receive FDA-approved agents chosen on the basis of specific biologic targets. This is the first prospective national clinical trial to examine the feasibility and safety of incorporating surgical biopsy into potential treatment strategies for children with DIPG.
NCT02082522
Photodynamic therapy (PDT) is a combination of a drug, porfimer sodium (Photofrin), which is activated by a light from a laser that emits no heat. This technique works to allow the medical doctor to specifically target and destroy abnormal or cancer cells while limiting damage to surrounding healthy tissue. The activation of the drug is done by lighting the abnormal areas using a fiber optic device (very fine fiber like a fishing line that permits light transmission) inserted into a flexible tube with a light called cholangioscope for the bile duct. The light will activate the porfimer sodium concentrated in the abnormal tissue, leading to its destruction. This research study will evaluate the efficacy and safety of PDT with porfimer sodium administered with Standard Medical Care (SMC) compared to SMC alone on the overall survival time of patients with non-operable advanced cholangiocarcinoma, a rare cancer of the bile ducts. It will involve 200 patients across North America and Europe. Other countries may participate if needed. Participation will last at least 18 months.
NCT02688725
Currently, there is no standard recommendation for using imaging studies to check patients for breast cancer recurrence who have been treated with mastectomy. The investigator proposes performing in-office ultrasound examinations of these patients to determine if this would be helpful in identifying an expected 5-7% of patients with breast cancer recurrences following mastectomy.
NCT02688764
This is a Phase 3, Open-label, Randomised, Active-controlled, Parallel Group, Multicentre Study to Investigate the Safety and Efficacy of PA21 (Velphoro®) and Calcium Acetate (Phoslyra®) in Paediatric and Adolescent CKD Patients with Hyperphosphataemia. The aim of this Phase 3 clinical study is to demonstrate similar efficacy of PA21 (Velphoro) in paediatric and adolescent patients with CKD, and to provide safety and dosing information for this patient population. The Phoslyra (comparator) group provides information for a descriptive comparison of PA21 against a commonly used calcium-based phosphate binder (calcium acetate).
