Study Details

Brief summary:

Background:

  • The Laboratory of Infectious Diseases (LID) Clinical Studies Unit (CSU) enrolls healthy volunteers into clinical studies to study infectious diseases.
  • Viruses can be highly infectious and contagious. They cause considerable illness in the United States each year and a good example of this is influenza (the flu). The LID CSU performs clinical studies to learn about these viral infections and assist in the development of vaccines and treatments for the infections. These clinical studies include influenza "challenge studies" as well as natural history studies and phase I trials involving vaccines for viruses carried by mosquitos such as Zika or Dengue virus.
  • In influenza challenge studies studies, doctors expose a person to a flu virus. Then they study the flu through the body's natural healing process. This information will help to find better ways to prevent the flu and may also improve treatments for the flu.
  • Natural history studies and phase I trials of new vaccines are performed so the researchers can learn how some viral infections occur and if new vaccines are safe and potentially effective in preventing the infections. In some of these studies, participants experience insect bites with special clean (non-infected) insects (such as mosquitos) to better understand the role of insects in these infections.

Objectives:

\- To screen healthy volunteers for future CSU studies.

Eligibility:

\- Healthy people between the ages of 18 and 65

Design:

  • The 3- to 5-hour screening exam includes the following:
  • Medical history and physical exam
  • Standard blood tests including pregnancy, Hepatitis B and C, and HIV tests
  • Standard urine drug testing
  • Electrocardiogram (ECG) to test heart rhythm and function
  • Chest x-ray
  • Eligible volunteers are enrolled in the study for up to 1 year, until they take part in a CSU study or are found to be ineligible to participate.
  • Volunteers may withdraw from the study pool at any time.

Healthy Volunteers: Accepted

  • INCLUSION CRITERIA:

1. Greater than or equal to 18 and less than or equal to 65 years old, and have no significant health abnormalities
2. Willing to consider taking part in a future LID Clinical Studies Unit healthy volunteer study
3. A female participant is eligible for this study if she is any of the following:
  • Of non-childbearing potential (i.e., women who have had a hysterectomy or tubal ligation or are post-menopausal, as defined by no menses in greater than or equal to 1 year)
  • Of childbearing potential but agrees to practice effective contraception or abstinence (from heterosexual sex) for 4 weeks prior to enrolling into a spceific study and during the study.

NOTE: Acceptable methods of contraception may include one or more of the following: 1) male partner who is sterile prior to the female participant's entry into the study and is the sole sexual partner for the female participant; 2) implants of levonorgestrel; 3) injectable progestogen;, 4) an intrauterine device with a documented failure rate of less than 1percent; 5) oral contraceptives; or 6) double barrier methods including diaphragm or condom with a spermicide.

4\. Willing to have samples stored for future research

EXCLUSION CRITERIA:

1. Self-reported history of any significant medical condition including but not limited to:

  • Chronic pulmonary disease (such as asthma, emphysema)
  • Chronic cardiovascular disease (cardiomyopathy, congestive heart failure, cardiac surgery, ischemic heart disease, known anatomic defects)
  • Chronic medical conditions requiring close medical follow-up or hospitalization during the past 5 years (diabetes mellitus, renal dysfunction, hemoglobinopathies)
  • Immunosuppression or cancer
  • Neurological and neuro-developmental conditions (e.g., cerebral palsy, epilepsy, stroke, seizures)
  • Drug and/or alcohol dependency and/or abuse
2. Any condition that, in the judgment of the Principal Investigator, is a contraindication to protocol participation or impairs the volunteer s ability to give informed consent
