Vaccinia Immune Globulin in Treating or Preventing Vaccinal Infection

Status Withdrawn

Clinical Trial Summary

The purpose of this study is to follow responses to treatment with vaccinia immune globulin (VIG) for safety and clinical benefit [during HIV vaccine research]. VIG is purified from human blood and used to treat serious infections of the vaccinia (smallpox vaccine) virus or similar viruses. It is the only treatment available for those viruses. The only available supply of VIG has developed a discoloration over time and therefore is considered an investigational new drug by the FDA. This study will allow it to be used for intramuscular injection in a controlled setting for people who may need it [during HIV vaccine research].

Clinical Trial Description

VIG (Human) is a component of plasma from persons vaccinated with vaccinia vaccine. It is the only product available for the treatment of vaccinia and other orthopox infections. The only lot currently available was released as a licensed product in 1995 but is being treated as an investigational new drug because of slight discoloration in the solution. This study makes existing stocks of VIG available as a short-term solution for the lack of a licensed immune globulin to treat vaccinal infections. Before receiving injections and 3 and 6 months after injections, patients are tested for HIV, hepatitis B, and hepatitis C with pre- and post-test counseling. Referrals for appropriate medical care are provided. Participants have multiple injections (depending on body weight) of VIG at 1 or 2 clinic visits. Following administration of VIG, participants are observed for 1/2 hour at the clinic. Participants return to the clinic for as many as 10 visits to monitor for any adverse reactions and signs and symptoms of vaccinia infections. On Days 7, 84, and 168 participants return to the clinic for evaluations and have blood drawn to check for the response to the VIG injections. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

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.
