NCT02858076
Although vitreous hemorrhage (VH) from proliferative diabetic retinopathy (PDR) can cause acute and dramatic vision loss for patients with diabetes, there is no current, evidence-based clinical guidance as to what treatment method is most likely to provide the best visual outcomes once intervention is desired. Intravitreous anti-vascular endothelial growth factor (anti-VEGF) therapy alone or vitrectomy combined with intraoperative PRP each provide the opportunity to stabilize or regress retinal neovascularization. However, clinical trials are lacking to elucidate the relative time frame of visual recovery or final visual outcome in prompt vitrectomy compared with initial anti-VEGF treatment. The Diabetic Retinopathy Clinical Research Network Protocol N demonstrated short-term trends consistent with a possible beneficial effect of anti-VEGF treatment in eyes with VH from PDR, including greater visual acuity improvement and reduced rates of recurrent VH as compared with saline injection. It is possible that a study with a longer duration of follow-up with structured anti-VEGF retreatment would demonstrate even greater effectiveness of anti-VEGF for VH to avoid vitrectomy and its attendant adverse events while also improving visual acuity. On the other hand, advances in surgical techniques leading to faster operative times, quicker patient recovery, and reduced complication rates may make prompt vitrectomy a more attractive alternative since it results in the immediate ability to clear hemorrhage and to perform PRP if desired, often as part of one procedure. This proposed study will evaluate the safety and efficacy of two treatment approaches for eyes with VH from PDR: prompt vitrectomy + PRP and intravitreous aflibercept injections.
NCT02232659
The SynCardia 70cc temporary Total Artificial Heart (TAH-t) is approved by the U.S. Food and Drug Administration (FDA) for use as a bridge to transplant for patients at risk of imminent (about to happen) death from irreversible biventricular heart failure. The purpose of this research study is to evaluate whether the TAH-t can support patients with life-threatening irreversible biventricular heart failure who are not eligible for transplantation. The TAH-t, when used for patients who are not eligible for transplant, is considered to be an investigational (not approved by FDA) use. This use is called destination therapy (DT). Nineteen (19) patients with life-threatening, biventricular failure who are not eligible for cardiac transplant will be enrolled in the Primary Arm of the study and followed for up to six months post-TAH-t implant. Safety will be evaluated by reviewing the adverse events that are experienced by the enrolled subjects and comparing them to previous experience of TAH-t patients who were waiting for a heart transplant. Since approximately 74% of patients with this condition would not be expected to live beyond six months, the benefit of the TAH-t for DT will be confirmed based on survival to six months without experiencing permanent disabling stroke-related deficits. After the six month follow-up visit, patients will continue to be followed under the study for up to five (5) years postTAH-t implant \[every six months for up to two years while supported with the TAH-t implant and then annually for another three years\]. Up to an additional 19 patients may be enrolled in the Secondary Arm of the study to further characterize the use of the TAH-t for DT in a broader patient population. Follow-up would be the same for patients enrolled in both arms of the study.
NCT04332991
ORCHID is a multicenter, blinded, placebo-controlled, randomized clinical trial evaluating hydroxychloroquine for the treatment of adults hospitalized with COVID-19. Patients, treating clinicians, and study personnel will all be blinded to study group assignment.
NCT01801007
The purpose of this study is to evaluate the safety and effectiveness of the MicroVention Flow Redirection Intraluminal Device (FRED) system when used in the treatment of wide-necked intracranial aneurysms.
NCT00485433
The purpose of this study is to evaluate three dose levels of SKY0402 compared with 105 mg of bupivacaine HCl.
NCT02897765
The purpose of this study is to evaluate if the treatment with NEO-PV-01 + adjuvant in combination with nivolumab is safe and useful for patients with certain types of cancer. The study also will investigate if NEO-PV-01 + adjuvant with nivolumab may represent a substantial improvement over other available therapies such as nivolumab alone. All eligible patients will receive NEO-PV-01 + adjuvant and nivolumab while on this trial.
NCT00413010
The primary objective of this study is to evaluate the efficacy of pregabalin as compared to placebo in the treatment of patients with general anxiety disorder (GAD). Efficacy will be measured by the improvement in the total Hamilton Anxiety Rating Scale (HAM-A) scores from baseline observed following 8 weeks of double-blind treatment or at earlier termination during the double-blind treatment phase and analyzed using a mixed linear model for repeated measures.
NCT01445080
This phase I/II trial is studying the side effects and best dose of sorafenib in treating young patients with relapsed or refractory solid tumors or leukemia. Sorafenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer.
NCT02847429
This is a multicenter, randomized, double-blinded, placebo-controlled, trial of oral crenolanib versus oral placebo in combination with best supportive care in subjects with advanced or metastatic GIST with a D842V mutation in the PDGFRA gene. Approximately 120 subjects will be randomized in a 2:1 ratio to receive either crenolanib 100 mg or matching placebo orally (PO) 3 times daily (TID) in combination with best supportive care.
NCT01531361
This phase I clinical trial studies vemurafenib with sorafenib tosylate or crizotinib in treating patients with advanced malignancies with BRAF mutations. Sorafenib tosylate and crizotinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Sorafenib tosylate may also stop the growth of advanced malignancies by blocking blood flow to tumors. Drugs used in chemotherapy, such as vemurafenib, 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 vemurafenib together with sorafenib tosylate or crizotinib may kill more cancer cells.
NCT03354598

NCT01151020
The Zenith® TX2® Low Profile TAA Endovascular Graft study is a clinical trial approved by US FDA to evaluate the safety and effectiveness of the Zenith® TX2® Low Profile TAA Endovascular Graft indicated for the treatment of patients with aneurysms/ulcers of the descending thoracic aorta having vessel structure suitable for repair.
NCT00368745
GAD subjects maintained on a stable dose of alprazolam for at least four weeks who meet eligibility criteria will be randomized to receive pregabalin vs matching placebo while simultaneously tapering off of alprazolam over 6 weeks. Subjects return weekly for assessment of safety/tolerability of pregabalin vs placebo as well as for assessment of anxiety and benzodiazepine withdrawal symptoms. Subjects successfully able to discontinue alprazolam, will continue 6 weeks of treatment with pregabalin vs placebo (free of benzodiazepine use). The efficacy and safety of pregabalin vs placebo for anxiety symptoms and ability to discontinue/remain free of alprazolam will be compared among pregabalin and placebo treated groups. Hypothesis is that a greater proportion of subjects will be successful in discontinuing and remaining free from benzodiazepines who were treated with pregabalin as compared to subjects treated with placebo.
