Immune Deficiencies clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT00404560 Recruiting - Immune Deficiencies Clinical Trials

Detection and Characterization of Infections and Infection Susceptibility

Start date: January 2, 2007
Phase:
Study type: Observational

This screening study will examine the causes of immune disorders affecting white blood cells, which defend against infections and will try to develop better means of diagnosis and treatment of these immune disorders. This is a 2 visit screening study and patients determined to be of interest for additional study or treatment will be asked to provide consent for enrollment into an appropriate NIH follow up study. This study does not cover the cost of the first visit to NIH for travel or lodgings but does cover the subsequent visit if there is one. A financial assessment may determine if the patient is eligible for financial assistance. This study does not enroll children under the age of 2. Patients known to have or suspected of having increased susceptibility to infections and their blood relatives may be eligible for this study, at the discretion of the principal investigator. Patients and family members may undergo the following procedures: - Personal and family medical history. - Physical examination and blood and urine tests. - Studies of breathing function (pulmonary function testing) - Dental examination. - Eye examination. - Genetic Testing - Stored specimens for future analysis - Microscopic examination of saliva, wound drainage or tissues removed for medical reasons for cell, hormone or DNA studies. In addition, patients will be asked to obtain permission for investigators to obtain their medical records, previous test results, or radiographic studies prior to the first visit. Patients will be asked to undergo imaging studies, such as a chest X-ray, CT scan or MRI scan. ...
