HIV and Emerging Infectious Diseases Program

Healthy Volunteer Studies

Studies of healthy volunteers are crucial to the understanding and treatment of diseases. They provide a baseline for measuring the extent of disease and provide important information about the safety and effectiveness of various treatments. The National Institutes of Health (NIH) houses the nation’s most renowned biomedical research institutions. The following clinical research studies are being conducted by NIAID and the NIH Clinical Center in Bethesda, Maryland.

The Influence of Cobicistat or Ritonavir on Dabigatran Pharmacokinetics and Pharmacodynamics in Healthy Volunteers

(P-3 – Protocol #13-CC-0160)

We will recruit 16 subjects who are HIV-negative, healthy individuals between 18 and 70 years of age. Volunteers must be in good general health, and be willing to take the medications dabigatran (Pradaxa, an anti-coagulant) and ritonavir (an HIV medication.)

After completion of the first 16 subjects, an additional 16 subjects will be recruited to take dabigatran with cobicistat (also an HIV medication.) Those volunteers who successfully completed the ritonavir portion of the study may also be considered to participate in the second arm of the study, if they wish. Each arm of the study requires seven visits in approximately a 54-day period. Four of those visits will last approximately one hour; three of those visits will last approximately 12 hours. Participants must provide their own transportation to the NIH. Volunteers will be compensated.​

Phase I Study of Safety and Immunogenicity of Ad4-HIV Vaccine Vectors in Healthy Volunteers

(NACHO, Protocol 14-I-0011)

The purpose of this study is to test experimental HIV vaccines to see if they are safe. HIV (human immunodeficiency virus) is the virus that causes AIDS (acquired immune deficiency syndrome). The vaccines use a live adenovirus as a carrier (or transporter). Adenoviruses are naturally occurring viruses that typically cause symptoms of a cold or conjunctivitis (a superficial eye infection). We hope that the adenovirus carrier will help the vaccines stimulate an immune response against HIV. An immune response is the body’s release of cells and substances that protect the body from infection and foreign matter. Another important goal is to see whether different ways of giving the vaccines cause different immune responses. We also want to see if the adenovirus in the vaccines is contagious or spreads to others. The study vaccine will not expose you to HIV infection. Volunteers will be compensated.​
