Washington Clinical Trials

A listing of Washington clinical trials actively recruiting patient volunteers.

Not to be confused with the nation's capital, the state of Washington is the furthest northwestern U.S. state, bordering the Pacific Ocean. Washington is dotted with more than 600 communities that meet the local definition of "city," but the largest are Seattle, Olympia, Spokane, and Tacoma. With a laid-back and friendly vibe, the state is often compared to California. It is home to the Seattle Space Needle and America's first revolving restaurant, as well as being the principal producer of apples in the nation. Swedish Medical Center First Hill, also in Seattle, is the biggest hospital, with nearly 700 beds.

International Registry for Severe Chronic Neutropenia

NCT00004342

OBJECTIVES: I. Document the clinical course of severe chronic neutropenia (SCN). II. Monitor and assess long term safety of primary treatment in SCN patients in the United States, Canada, Europe, and Australia. III. Study the incidence and outcome of adverse events such as osteoporosis, splenomegaly, cytogenetic abnormalities, myelodysplastic syndrome, and leukemia. IV. Evaluate growth and development and hematologic parameters. V. Monitor for clinically significant changes in primary treatme ...

A Prospective Database of Infants With Cholestasis

NCT00061828

Biliary atresia, idiopathic neonatal hepatitis, and specific genetic cholestatic conditions are the most common causes of jaundice and hyperbilirubinemia that continue beyond the newborn period. The long term goal of the Childhood Liver Disease Research Network (ChiLDReN) is to establish a database of clinical information and plasma, serum, and tissue samples from cholestatic children to facilitate research and to perform clinical, epidemiological and therapeutic trials in these important pediat ...

Conditions: Biliary Atresia, Neonatal Cholestasis

Genetic Analysis in Identifying Late-Occurring Complications in Childhood Cancer Survivors

NCT00082745

This clinical trial studies cancer survivors to identify those who are at increased risk of developing late-occurring complications after undergoing treatment for childhood cancer. A patient's genes may affect the risk of developing complications, such as congestive heart failure, avascular necrosis, stroke, and second cancer, years after undergoing cancer treatment. Genetic studies may help doctors identify survivors of childhood cancer who are more likely to develop late complications.

Conditions: Childhood Malignant Neoplasm

TrialNet Pathway to Prevention of T1D

NCT00097292

Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T ...

Conditions: Diabetes Mellitus, Type 1

Mucopolysaccharidosis I (MPS I) Registry

NCT00144794

The Mucopolysaccharidosis I (MPS I) Registry is an ongoing, observational database that tracks the outcomes of patients with MPS I. The data collected by the MPS I Registry will provide information to better characterize the natural history and progression of MPS I as well as the clinical responses of patients receiving enzyme replacement therapy, such as Aldurazyme (Recombinant Human Alpha-L-Iduronidase), or other treatment modalities. The objectives of the Registry are: To evaluate the long- ...

Fabry Disease Registry & Pregnancy Sub-registry

NCT00196742

The Fabry Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Fabry disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The primary objectives of the Registry are: To enhance the understanding of the variability, progression, and natural history of Fab ...

Conditions: Fabry Disease

Pompe Disease Registry Protocol

NCT00231400

The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: To enhance understanding of the ...

Conditions: Glycogen Storage Disease Type II, Pompe Disease

Longitudinal Study of Urea Cycle Disorders

NCT00237315

Urea cycle disorders (UCD) are a group of rare inherited metabolism disorders. Infants and children with UCD commonly experience episodes of vomiting, lethargy, and coma. The purpose of this study is to perform a long-term analysis of a large group of individuals with various UCDs. The study will focus on the natural history, disease progression, treatment, and outcome of individuals with UCD.

Conditions: Brain Diseases, Metabolic, Inborn, Amino Acid Metabolism, Inborn Errors, Urea Cycle Disorders
