Raleigh-Durham, North Carolina Clinical Trials

This is a multi-center randomized study of three doses of radiation (assigned 1:1:1) delivered by the TheraSight(TM) Brachytherapy System in participants with choroidal neovascularization (CNV) secondary to wet (exudative) AMD. Each participant receives a single dose of radiation delivered by one-time only brachytherapy. Participants are followed for three years after ...

We are establishing a registry-based cohort and repository of biological (e.g. blood, urine,saliva, etc.) and environmental (e.g. household dust) specimens (approximately 20,000 participants) in which the donated specimens are linked to the donor s identities, contact information, and some basic demographics through a personal identification number (PIN). Specimens are available ...

The objective is to define the signaling pathways activated by lipopolysaccharide (LPS) and other selected innate immunity stimuli, and the downstream inflammatory functional consequences, in human leukocytes in vitro. Adult (greater than or equal to 18 - 65 years old), nonpregnant, healthy volunteers will have 320 ml of whole blood ...

Most autoimmune diseases are thought to develop as a result of chronic immune activation and dysregulation after selected environmental exposures in genetically susceptible individuals. Based on prior studies suggesting roles for noninfectious and infectious agents in the development of myositis, as well as the known clinical, epidemiologic and genetic differences ...

Research to advance the characterization of environmental and chemical exposures through improved exposure assessments, at both the individual and population levels, is a research priority identified in the Strategic Research Action Plan for the U.S. Environmental Protection Agency (EPA) s Chemical Safety for Sustainability (CSS) program (EPA 2012) and the ...

Functional hypothalamic amenorrhea (HA) is a reversible form of hypogonadotropic hypogonadism (HH) that can be triggered by stressors such as exercise, nutritional deficits, and psychological stress. Dysfunction of the hypothalamic component of the reproductive axis plays a key role in functional HA and is manifest by an altered pattern of ...

This study will be a prospective, longitudinal, observational, single-center, exploratory, natural history study to collect samples and data that will enable prospective explorations of the interaction between environmental exposures and disease progression over time in moderate-severe atopic asthmatics with persistent disease, and facilitate the formation of mechanistic hypotheses. Environmental and ...

The Registry was originally initiated on 03 May 2005, as part of a program of enhanced pharmacovigilance. Following new European Union Pharmacovigilance legislation, pregnancy registries are to be considered as post-authorization safety studies (PASS). The ongoing Registry will therefore be converted into a PASS study in Q1 2014. Exposed pregnancies ...

This is a multicenter (when more than one hospital or medical school team work on a medical research study), prospective (study following participants forward in time), open-label (all people know the identity of the intervention) study of infliximab in pediatric participants with inflammatory bowel disease. The study consists of 3 ...

The study will consist of the following periods: Screening (Days -21 to -1), Transplant (Day 0), Post-Transplant (Day 0/post-skin closure through 12 months post-transplant). All subjects will enter into a Screening Period (Days -21 to -1 prior to transplant), undergo a Transplant (Day 0 [zero]), and are then to be ...
