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 study is a prospective, multi-center, proof of principle, phase I human safety study evaluating the sequential treatments of the Avance Nerve Graft, a commercially available decellularized processed peripheral nerve allograft, with autologous Bone Marrow Aspirate Concentrate (BMAC), a source of stem cells, for the repair of peripheral nerve injuries up to 7 cm in length. The purpose of this study is to establish a knowledge product, evaluating the safety profile of the Avance Nerve Graft, followed by the application of BMAC to support further investment into the promising area of using stem cells in conjunction with scaffolds.
Background: Secondary central nervous system lymphoma (sCNSL) is cancer that has spread to the central nervous system. Most drugs used to treat it do not cross the blood-brain barrier. This makes it hard to treat. Researchers hope that a new combination of drugs may be able to help. Objective: To find a better way to treat sCNSL. Eligibility: People ages 18 and older with sCNSL Design: Participants will be screened with: - Medical history - Physical exam - Blood, urine, and heart tests - Eye exam - Tissue or tumor biopsy - Collection of cerebrospinal fluid - CT, PET, and MRI scans: Participants will like in a machine that takes pictures of the body. - Bone marrow aspirations or biopsies: A needle will be inserted into the participant s hipbone. The needle will remove a small amount of marrow. Participants will take the study drugs in 21-day cycles. They will take some drugs by mouth. They will take others through a catheter: A small tube will be inserted into a vein in the arm, neck, or chest. They may have drugs given through a catheter placed through the brain or injected into the spinal canal. Participants will have regular visits during the study. These will include repeats of the screening test. They may also provide a saliva sample or have a cheek swab. Participants will have up to 4 treatment cycles. Participants will have a follow-up visit 30 days after their last treatment dose. Then they will have visits every 3-6 months for 3 years and then yearly....
The objective of this study is to examine how adenocarcinoma of the prostate treatment differentially affects African American men's ability to work and to describe and compare changes in work ability (as measured through self-reported global work ability item) reported by African American and white adenocarcinoma of the prostate survivors before treatment and 6 months after treatment completion.
Heart failure (HF) patients with supportive caregivers have better physical health, emotional health, and quality of life. But caregivers have an increased risk of caregivers' own worsening health and often feel a sense of burden related to caregiving. However, caregivers receive very little support to balance caring for the patient with caring for themselves. Therefore, this research will provide a program for caregivers of advanced heart failure patients to build on the caregiver's strengths, sense of purpose, and set goals for healthy lifestyle changes. The investigators believe that caregivers who receive the program will have better quality of life, less sense of burden, and a healthier lifestyle.
The purpose of this study is to better understand the mechanism of action (MoA) of cladribine tablets by exploring the effect on central nervous system (CNS) and blood biomarkers relevant in the relapsing forms of multiple sclerosis (RMS; to include relapsing-remitting MS [RRMS] or active secondary progressive MS).
Asthma is the most common chronic disease of childhood and is a leading cause of emergency medical treatment. For children experiencing an asthma exacerbation, emergency department (ED) guidelines recommend early systemic corticosteroid (CS) administration, since studies have shown associated, time-sensitive, decreases in hospital admissions and ED length-of-stay (LOS). For patients who are treated by 911 emergency medical services (EMS) first, there exists an opportunity for even earlier administration of CS, prior to ED arrival. Yet, preliminary data demonstrate that currently less than 10% of EMS pediatric asthma patients receive CS prior to ED arrival. Given the known time-sensitivity of CS' effects on patient outcomes, the investigators hypothesize that even earlier EMS administration of CS will decrease hospital admissions, ED LOS, and intensive care unit admissions for pediatric patients with an acute asthma exacerbation. Using a pragmatic observation stepped wedge design in multiple EMS agencies, we will enroll patients over a three-year period to analyze clinical outcomes and comparative costs of EMS CS administration, and how both are influenced by EMS transport time. That novel combination of analyses will help build evidence-based guidelines adaptable for diverse EMS agencies nationwide.
This study evaluates whether addition of the thromboxane receptor antagonist to chronic aspirin therapy improves endothelial function and reduces non-platelet thromboxane generation in patients with established cardiovascular disease. Half of participants will receive ifetroban and the other half will receive matchcing placebo for the 4 week study period.
This is a neoadjuvant study to determine the feasibility and tolerability of 2 weeks of a very low carbohydrate ketogenic diet in combination with letrozole for patients with early stage operable ER+disease.
This study evaluates mirdametinib (PD-0325901) in the treatment of symptomatic inoperable neurofibromatosis type-1 (NF1)-associated plexiform neurofibromas (PNs). All participants will receive mirdametinib (PD-0325901). Eligible participants may continue in a long-term follow-up phase.
The goal of this study is to examine whether a brief, exposure-based treatment (Written Exposure Therapy) approach is just as effective in the treatment of posttraumatic stress disorder (PTSD) compared with a more commonly used time-intensive approach called Prolonged Exposure. One hundred and fifty Veterans diagnosed with PTSD will be randomly assigned to either Written Exposure therapy or Prolonged Exposure. Veteran participants will be assessed at pre-treatment, and 10-, 20-, and 30- weeks post first treatment session. Primary outcome measure will be PTSD symptom severity. The secondary outcome measure will be quality of life. In addition, treatment dropout during the first five sessions will be examined. WET is expected to have a lower treatment dropout rate relative to PE.
