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.
For many patients with hematologic disorders and bone marrow failure, hematopoietic stem cell transplantation (HSCT) or cellular therapy (CART) offers a curative treatment option. Patients after SCT or CART have a variable period of immune deficiency in the post-treatment period. The response to vaccination may affect the outcome of the transplant patients. the immunogenicity of vaccines in this immunosuppressed population is uncertain and variable. HSCT and CAR-T recipients are in a COVID-19 high-risk group and conferring immunity by vaccination at the earliest effective timepoint is desirable. At present, the immunogenicity and efficacy of SARS-CoV-2 vaccines in immune-impaired patients including autologous and allogeneic HSCT recipients is unknown. Furthermore, the impact of GvHD and IST on SARS-CoV-2 vaccine immunogenicity is unknown. the investigators aim to evaluate the vaccination response to COVID vaccines after SCT and CART
Primary Objective: • To evaluate the safety and tolerability of cAd3-EBO-S and cAd3 Marburg vaccines when administered Intramuscular (IM) at a dose of 1 x 10^11 particle units (PU) to healthy adults. Secondary Objectives: - To evaluate the antibody response to Monovalent Chimpanzee Adenoviral Vectored Filovirus Ebola-S (cAd3-EBO-S) and Monovalent Chimpanzee Adenoviral Vectored Filovirus (Marburg) (cAd3 Marburg) vaccines as assessed by antigen glycoprotein (GP) specific (enzyme-linked immunosorbent assay) ELISA - To collect sufficient post-vaccination plasma to support further development of filovirus assays
Study to support the mental and physical well-being of US health care workers during the COVID-19 pandemic and ensure high-quality care for patients through Stress First Aid.
Randomized, placebo controlled study to determine if nebulized heparin may reduce the need for mechanical ventilation in hospitalized patients with the novel coronavirus, also known as COVID-19. This will be a part of a larger meta-trial.
The purpose of this randomized, controlled feasibility investigation is to characterize pharmacologically induced ventilatory depression after anesthesia and examine how is affected by the amount of supplemental oxygen patients are receiving in the immediate postoperative period.
This Phase III study will assess whether AZD7442 (a combination of 2 mAbs) can safely treat outpatient adults with COVID-19 and prevent either severe COVID-19 or death.
This study will assess the feasibility and acceptability of a positive psychology intervention, The Gratitude Gallery, for increasing gratitude in adults. The study hypothesizes that participants will find the activity feasible and acceptable and complete the intervention as directed. The project also hypothesizes that those that complete the intervention will show an increase in self-reported gratitude, as well as a decrease in symptoms of anxiety and depression.
The purpose of this 6-week, double-blind, placebo-controlled, crossover study is to explore new treatment options for people with depression who have high inflammation and anhedonia. Thirty-five male and female participants with depression, between the ages of 25-55 years of age, will be randomized to two study tracks (A and B) to receive both placebo and three doses of L-DOPA, given in different orders. Increases or decreases in each dose will occur gradually over 6 weeks of the study. Participants will complete lab tests, medical and psychiatric assessments, neurocognitive testing and functional MRI (fMRI) scans as part of the study. The total length of participation is about 2 months.
This Phase 2 study is conducted to investigate the safety and efficacy of runcaciguat in the treatment of diabetic retinopathy. To assess efficacy, the retinal morphology will be investigated by 7-field color fundus photography for central assessment of the diabetic retinopathy severity score, or DRSS. Two-step DRSS improvement at 24 weeks of treatment will be the primary efficacy endpoint. DRSS assessments are repeated after completion of 48 weeks of treatment. In addition, vision threatening complications will be recorded throughout the study and assessed as secondary efficacy endpoint.
The objective of this study is to clinically develop and evaluate a machine learning approach to improve the performance and data interpretation of the PhotoniCare OtoSight Middle Ear Scope in pediatric patients presenting at the primary care office for suspected ear infections. In this observational study, results of OtoSight imaging will not affect patient standard of care.
