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.
This is an open-label, single-arm, multicenter Phase II safety and efficacy study of combination therapy with pembrolizumab and Sylatron (Peginterferon alpha-2b) in patients with advanced cholangiocarcinoma who have progressed on or cannot tolerate frontline chemotherapy.
The participant is being asked to be a subject in this research study because the participant may have a disorder that can cause optic nerve damage and impairment of his/her visual function which is called optic neuropathies (ON). Optic neuropathy refers to damage to the optic nerve (a "cable" connecting the eyes and the brain to transmit the visual signals) due to any cause.In this study, the investigator is using magnetic resonance imaging (MRI) and ophthalmic measures such as optic coherent tomography(OCT), which are non-invasive imaging tests to measure the changes in eye globe shape ,the flow of blood and brain fluid. It is hoped that this study will provide new knowledge that may allow the investigator to better understand the cause of symptoms associated with optic neuropathy and ways to better monitor what is happening.
A double-blinded, placebo-controlled study of Dimethyl fumarate (DMF) in 34 Systemic Sclerosis-Pulmonary Hypertension (SSc-PAH) patients. The study will determine safety and the primary outcome variability for DMF in treating SSc-PAH; the primary outcome of clinical efficacy in this pilot trial will be improvement in 6-minute walk distance (6MWD).
This is a Phase 3, multicenter, randomized, masked, controlled, parallel group study of 12 months duration in treatment naïve subjects with RVO.
This is a randomized, double-Blind, placebo-controlled Phase 2a study to evaluate the efficacy and safety of SUNPG1622.
The purpose of this research study is to compare the forearm free flap of patients with a traditional split thickness skin graft and those repaired with Integra (a skin substitute that helps to provide wound closure) and a split thickness skin graft. The study team will be looking at the subject's satisfaction with how the skin graft site looks and how well the skin graft site is functioning.
This pilot study aims to investigate the efficacy of fMRI-targeted repetitive transcranial magnetic stimulation (rTMS) in treatment of major depression associated with traumatic brain injury (TBI). Half of patients will receive active treatment, while the other will receive a sham treatment with the option of receiving open-label active treatment afterwards.
A prior study by the principal investigator of this project identified dopamine- and oxytocin-related brain pathways that showed a diminished response when addicted mothers viewed the faces of their own vs. unknown infants, compared with non-addicted mothers. These areas include the hypothalamus, striatum and ventromedial prefrontal cortex. In addition, the investigators plan to examine activation patterns within the salience network, which includes the anterior cingulate cortex and the anterior insula. Oxytocin, a neuropeptide with decreased blood levels seen in addicted mothers, is integrally involved in maternal brain and behavioral responses. When administered intranasally, the pilot data has shown enhanced activation of the striatum, prefrontal cortex (PFC) and amygdala. The purpose of this study is to continue and expand upon the previous investigation of maternal addiction, by conducting a randomized, double-blinded, placebo controlled, crossover study of intranasal oxytocin on maternal brain responses. 150 mothers from the University of Iowa and the Yale Child Study Center will be enrolled (75 with a history of drug addiction and 75 matched control mothers), along with their 2 to 12-month-old infants, to participate in four study visits over a two-month period.
The aim of study is to determine if 99mTc Annexin V-128 (AxV- 128/Tc) single photon emission computed tomography (SPECT)-computed tomography (CT) can detect perioperative lung injury. The investigators will study patients undergoing major surgery, specifically Whipple procedures (pancreatico-duodenectomies) and compare AxV-128/Tc SPECT-CT scans before and after surgery in Chronic Obstructive Pulmonary Disease (COPD) and non-COPD patients.
Gluteus medius tendinopathy, which is often referred to as Greater Trochanteric Pain Syndrome, is characterized by pain in the lateral aspect of the hip that is aggravated by side lying, stair climbing, and walking. Treatment is currently limited to lifestyle modifications, corticosteroid injections, physical therapy, and open and endoscopic surgical repair. Platelet rich plasma (PRP) injections contain important growth factors that are essential in the healing and tissue formation processes. However, the extent to which PRP is more efficacious than whole blood in tendinopathy remains unclear. In this double-blind randomized trial, patients will be allocated to receive either a PRP or whole-blood injection. Post-procedure assessments will occur at 6 weeks, 3 months, 6 months, 9 months, and 1 year.
