Dexamethasone Clinical Trials

This study will look at the safety and tolerability of the new drug MLN9708 in combination with the existing drugs panobinostat and dexamethasone among patients with relapsed or refractory multiple myeloma. This study will also look at the response and clinical benefit of the treatment and the progression-free survival and overall survival of study participants. Read Less

This study is a Phase I study to investigate the addition of inhaled Ipratropium bromide to standard therapy in the treatment of severe asthma attacks in children admitted to the Pediatric Intensive Care Unit. Half of the subjects will receive inhaled Ipratropium, and half will receive an inhaled placebo. Read Less

This study will examine the use of the dexamethasone implant (Ozurdex) in patients with macular edema associated with an epiretinal or preretinal membrane requiring surgical intervention. After the surgery is performed (pars plana vitrectomy), an Ozurdex implant will be placed in the eye. Patients will be followed for 1 year. Read Less

This study will test the hypothesis that adding dexamethasone significantly prolongs the duration of ropivacaine and bupivacaine analgesia, and that the magnitude of the effect differs among the two local anaesthetics.. Participants will be patients undergoing shoulder surgery with an interscalene nerve block. Read Less

Evidence thus suggests that steroid administration, tight glucose control, and avoidance of deep anesthesia may decrease perioperative morbidity by reducing the inflammatory response to surgery. Using a three-way factorial approach, the investigators thus propose to test the primary hypotheses that major perioperative morbidity is reduced by: 1) low-dose dexamethasone; 2) intensive perioperative glucose control; and 3) lighter anesthesia. Secondary hypotheses include that each intervention reduces circulating concentrations of the inflammatory marker CRP, and that there is a correlation between C-reactive protein (CRP) and post-operative complications. Anesthetic sensitivity predicts major and minor complications, and delirium Other secondary hypotheses are that each intervention, reduces minor surgical complications, reduces postoperative nausea and vomiting (PONV), reduces postoperative delirium, speeds hospital discharge, improves quality of life (SF-12v2 Health Survey, Christensen's VAS fatigue score), and reduces all-cause one-year mortality.

This phase I trial studies the side effects and the safety of injecting HSV1716 (a new experimental therapy) into or near the tumor resection cavity. The injection will be done at the time of surgery. HSV1716 is a virus that has a gene which has been changed or removed (mutated) in such a way that lets the virus multiply in dividing cells of the tumor and kills the tumor cells. Read Less

The investigators hypothesize that preoperative administration of 8 mg IV dexamethasone will benefit patients' perceived quality of recovery after surgery. Read Less

Patients undergoing rotator cuff repair or subacromial decompression at the investigators institution are frequently hospitalized overnight due to inadequate pain relief after resolution of interscalene brachial plexus blocks. For ropivacaine 0.5%, the investigators usual local anesthetic, previous studies report an analgesic duration of 11.1 ± 5 hours without epinephrine and approximately 12 hours with epinephrine. Consequently, a method of prolonging analgesia from a brachial plexus block without the extra equipment and logistical difficulties of indwelling catheters would benefit both patients and caregivers. A potential approach is use of adjuvant drugs that prolong block duration when added to the local anesthetic. In addition to the usual adjuvant anesthetic drugs, investigators have begun to evaluate glucocorticoids as adjuvants for regional anesthesia. Known for their anti-inflammatory, analgesic, immunosuppressive, and antiemetic properties, these corticosteroids exert their effects by inhibition of phospholipase A2 as well as changes in cell function induced by glucocorticoid receptor activation. Although associated with significant toxicity when administered in large doses for long periods, emerging literature suggests that a single perioperative dose of glucocorticoid is safe. Several studies, including a recent trial at the investigators institution, have demonstrated the efficacy of dexamethasone in prolonging regional anesthetics. Available data thus suggest that combining glucocorticoids with local anesthetics prolongs block duration. However, systemic glucocorticoids have also been shown to reduce postoperative pain. This raises the question whether the beneficial effects of adding glucocorticoid to a regional anesthetic is solely due to local effect or is mediated at least in part by systemic action. Previous trials, however, have not addressed this important issue. If this beneficial effect of analgesic duration is mediated by systemic action, adding dexamethasone to the local anesthetic mixture may be unnecessary. Although no study has reported neurotoxicity from perineural dexamethasone and laboratory data appear to confirm the safety of this route, achieving similar results with more conventional administration would be desirable for two reasons. First, conventional intravenous dosing is convenient, useful for other reasons (for example, postoperative nausea prophylaxis), and well-studied. Second, equivalent (or not equivalent) results from systemic dosing would provide valuable information about the mechanism behind dexamethasone's effect on block duration. Read Less

RATIONALE: Hyperbaric oxygen may increase blood flow and decrease swelling in areas of the brain damaged by radiation therapy. Giving hyperbaric oxygen therapy together with dexamethasone may be an effective treatment for radiation necrosis of the brain. PURPOSE: This randomized clinical trial is studying how well hyperbaric oxygen therapy works in treating patients with radiation necrosis of the brain. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy consisting of liposomal doxorubicin, vincristine, and dexamethasone in treating patients with newly diagnosed or previously treated multiple myeloma. Read Less

RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Thalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Giving arsenic trioxide together with ascorbic acid, dexamethasone, and thalidomide may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with ascorbic acid, dexamethasone, and thalidomide work in treating patients with multiple myeloma. Read Less

The FSGS Clinical Trial is a multi-center, prospective, controlled, open label randomized trial designed to determine if treatment with mycophenolate mofetil (MMF) in conjunction with pulse steroids is superior to treatment with Cyclosporine-A (CSA) in inducing remission from proteinuria over 12 months.
