Filter by:The purpose of this study is to assess the relationship between bupropion, stimulant use and relapse, ADHD (Attention Deficit Hyperactivity Disorder), and measures of mood, drug craving, and inhibitory control in individuals enrolled in inpatient treatment for stimulant-use disorder with and without ADHD. The experimenters hypothesize that Bupropion and Contrave (Bupropion/Naltrexone) will increase inhibitory control and decrease drug craving and depressive symptoms in recently abstinent stimulant users in inpatient treatment with effects greater than those seen in recently abstinent stimulant users completing inpatient treatment as usual. An additional hypothesis is that relapse rates after leaving inpatient treatment in the group receiving bupropion will be lower than those of the group completing inpatient treatment as usual. The study design consists of four assessments of drug craving, inhibitory control, impulsive choice, and mood (depression and anxiety). The timepoints for these assessments include: A. baseline after entering treatment B. 2 weeks after starting drug C. 8 weeks after starting drug, and D. 1 month after leaving treatment. Following eligibility screening, 60 stimulant users will be enrolled in one of 3 groups. Group 1 Bupropion Active Group: 20 subjects will receive bupropion for 8 weeks during inpatient treatment. Group 2 Contrave Active Group: 20 subjects will receive Contrave for 8 weeks during inpatient treatment. Group 3 Control Group: 20 subjects enrolled in inpatient treatment will complete treatment as usual as well as the four assessments (A-D) described above but will not receive drug (convenience control). Half of the subjects in each group will be diagnosed with ADHD and half will not, for a total of 10 subjects per group with ADHD.
This phase I trial investigates the side effects and effectiveness of chemotherapy followed by a donor (allogeneic) stem cell transplant when given to patients with high grade brain cancer. Chemotherapy drugs, such as fludarabine, thiotepa, etoposide, melphalan, and rabbit anti-thymocyte globulin, 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. Giving chemotherapy before a donor stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets and may help destroy any remaining cancer cells.
There is no current accepted and predictably effective ablative therapy for patients with recurrent paroxysmal atrial fibrillation after prior pulmonary vein isolation (PVI). This study will compare redo PVI with hybrid epicardial ablation incorporating posterior wall isolation and LAA clip, and redo PVI.
This phase Ib trial investigates the side effects of the combination of nivolumab and ipilimumab, and to see how well they work in treating patients with cancers that have come back (relapsed) or does not respond to treatment (refractory) and have an increased number of genetic changes. 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. Tumor mutational burden (TMB) is the total amount of genetic changes or "mutations" found in tumor cells. Some studies in adults with cancer have shown that patients with a higher TMB (an increased number of genetic changes) are more likely to respond to immunotherapy drugs. There is also evidence that nivolumab and ipilimumab can shrink or stabilize cancer in adult patients with cancer. This study is being done to help doctors learn if the combination of nivolumab and ipilimumab can help children, adolescents, and young adults patients live longer.
This is a prospective, single-center, open-label phase Ib study aimed at determining a recommended phase II dose of INCB053914 and pomalidomide with dexamethasone. The trial will follow a 3 + 3 phase I dose-escalation design.
A randomized, multi center, open label, two-period, single dose, crossover study to evaluate the bioavailability and safety of Paclitaxel Injection Concentrate for Suspension in Locally Recurrent or Metastatic Breast Cancer subjects.
The purpose of this study is to determine whether a medication, fluvastatin, can change melanoma to a state that is less likely to metastasize or recur. Fluvastatin is experimental in this setting because it is not approved by the Food and Drug Administration (FDA) for treatment or prevention of melanoma. However, fluvastatin has been approved by the FDA for treating high cholesterol.
Current international guidelines recommend a three-month blanking period after pulmonary vein isolation (PVI) for atrial fibrillation (AF). Early recurrence of atrial tachyarrhythmia (ERAT; comprising of AF, left atrial tachycardia and atrial flutter) is common, occurring in up to 65% of patients, but in the first month is generally thought not to predict long-term AF recurrence, and re-intervention is not recommended. Suggested causes for ERAT include inflammation and arrhythmogenic structural changes caused by ablation lesions. Early, purely inflammatory ERAT would not lead to late AF recurrence as pulmonary vein reconnection is established as the main factor associated with long-term recurrence in paroxysmal AF. Previous studies have shown ERAT in the second to third month (rather than first month) to be a stronger predictor of late AF recurrence, due to presumed reduction in the contribution of the acute inflammatory response after this. Biochemical data have shown that the post-ablation inflammatory phase is usually limited to the first month after both radiofrequency (RF) and cryoballoon (CB) ablation, though inflammatory markers have been shown to be less elevated following CB PVI. Histologically, lesions formed by the two modalities differ significantly. RF lesions are characterised by irregular boundaries and significant disruption to the endothelium, exposing the sub-endothelial layer and resulting in significant and sustained platelet activation, changes which can last for many months. CB lesions on the other hand, are observed as well demarcated and homogenous within one week, with reduced thrombogenicity, which may lead to reduced inflammation. ERAT following CB ablation cannot be accurately predicted by inflammatory response and it is postulated that endothelial function may play a role in the development of ERAT in such patients. Some studies have shown reduced recurrence rate and re-hospitalisation amongst the CB population, including the FIRE and ICE trial, potentially resulting in a better patient experience with CB and the possibility of a shorter blanking period. Post-ablation inflammatory response is more predictive of ERAT following RF than CB PVI, and the latter is considered to be associated with less inflammation. There is however, a paucity of data evaluating endothelial function post-AF ablation and its correlation with ERAT or late recurrences of arrhythmia. Given that earlier re-intervention in patients with ERAT in the third month of the blanking period can result in greater outcomes with respect to late recurrence of AF, if it can be demonstrated that endothelial function testing in the first few months post-CB PVI can be predictive of later ERAT, then shortening the blanking period following CB PVI and performing repeat ablation to control troublesome later ERAT may reduce overall patient morbidity and re-hospitalisation. The purpose of this novel pilot study is to examine the relationship between the post-ablation inflammatory response, endothelial function and timing and frequency of ERAT for patients undergoing RF and CB PVI for paroxysmal or short-lived persistent (less than 6 months' duration) AF. If the initial data provides hypothesis generating information, the aim would be to perform the study on a larger basis with higher statistical power to determine whether early post-ablation endothelial function testing can predict recurrences and identify those suitable for earlier re-intervention.
This phase II trial studies how well vorinostat and combination chemotherapy before donor stem cell transplantation work in treating patients with aggressive B-cell or T-cell non-Hodgkin lymphoma that has come back (relapsed). Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as busulfan, gemcitabine, and clofarabine, 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 vorinostat together with combination chemotherapy before donor stem cell transplantation may help to control lymphoma.
The aim of this study is to test whether the realization of 3 courses of intra-arterial chemotherapy of idarubicin-lipiodol without embolization, administered non-selectively in the hepatic artery, following the percutaneous tumour ablation of a hepatocellular carcinoma, could constitute an effective adjuvant treatment to reduce the rates of local and intrahepatic distant recurrence and thus improve the survival without hepatic progression.
