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.
The primary objective of the study is to compare the clinical efficacy of high-dose quadrivalent influenza vaccine (QIV-HD) to standard-dose quadrivalent influenza vaccine (QIV-SD) in participants 6 months through 35 months of age for the prevention of laboratory-confirmed influenza illness caused by any influenza A or B type. The secondary objectives of the study are: - To compare QIV-HD to QIV-SD: - in participants 6 months through 35 months of age for the prevention of laboratory-confirmed influenza illness caused by any influenza A or B type using a more stringent threshold - in participants 6 months through 35 months of age for the prevention of laboratory-confirmed protocol-defined influenza-like illness caused by viral strains similar to those contained in the vaccine. - in participants 6 months through 23 months of age for the prevention of laboratory-confirmed influenza illness caused by any influenza A or B types. - To compare hemagglutination inhibition (HAI) immune response of QIV-HD to QIV-SD in participants 6 months through 35 months of age - To describe the HAI, seroneutralization (SN), and anti-neuraminidase (NA) immune response - To describe the immune response to revaccination in Season 3 (Northern Hemisphere) - To describe the safety profile of each vaccine
This phase I trial investigates the side effects and determines the best dose of an immune cell therapy called GD2CART, as well as how well it works in treating patients with osteosarcoma or neuroblastoma that has come back (relapsed) or does not respond to treatment (refractory). T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this trial will come from the patient and will have a new gene put in them that makes them able to recognize GD2, a protein on the surface of tumor cells. These GD2-specific T cells may help the body's immune system identify and kill GD2 positive tumor cells.
Adults and children undergoing medical care (inpatient or outpatient) often experience pain and anxiety either as a result of their medical condition or a side effect of medical procedures. The purpose of this study is to create a registry of patients using virtual reality (VR) mindfulness therapy through different aspects of their medical care to determine if VR mindfulness therapy is more effective than the standard of care (i.e., no technology based distraction) for treating or preventing anxiety and pain in adults and children suffering from chronic pain, GI conditions where pain is a common symptom, or undergoing any painful medical procedure (i.e. IV access, blood draws, endoscopy, surgery). The anticipated primary outcome will be reduction of pain and anxiety for both acute and chronic pain.
Investigating the efficacy of a form of TMS called theta-burst stimulation for restricted and repetitive behavior in ASD.
Use of novel radio-pharmaceutical Rhodamine 6G to determine myocardial blood flow
The purpose of this study is to evaluate the safety, tolerability and efficacy of GV-971 in mild to moderate Alzheimer's disease.
The investigators propose an open label, non-blinded, single center randomized controlled feasibility study to find the optimal initial HFNC flow rate in children less than 12 months old with clinically diagnosed moderate to severe bronchiolitis. This feasibility study is projected over December 2020 to April 2023. The study is consisted of 3 arms, comparing HFNC therapy at 1 L/kg/min, 1.5 L/kg/min, and 2 L/kg/min (20 L/min max). Moderate to severe bronchiolitis is defined clinician's assessment for the need for ICU level of care. The primary outcome is treatment response to HFNC therapy defined by RDAI/Respiratory Assessment Change Score (RACS) ≥ 4 at 4 hours of therapy. Secondary outcome measures comprise of treatment failure requiring an escalation of care during the first 24 hours of HFNC therapy, duration of HFNC and simple nasal cannula therapy, duration of simple nasal cannula therapy, hospital and PICU length of stay (LOS), time to treatment failure, and adverse events.
This is a research study to develop a noninvasive test using ultrasound to determine when urgent, life-saving treatment is needed for those with severe traumatic brain injuries.
This is an open-label, phase 1b study to evaluate the safety, tolerability and preliminary efficacy of IBI188 in combination with Azacitidine in newly diagnosed higher risk MDS patients.
Open-label randomized study comparing the current standard of care treatment of Covid-19 in hospitalized patients with evidence of cardiac injury vs. a group of the same type of patients treated with colchicine plus current standard of care.
