Healthy Clinical Trial - Experimental Ebola Vaccine Trial

Status Completed

Clinical Trial Summary

This study will test the safety of an experimental vaccine developed to protect against Ebola virus infection and to determine if the vaccine induces an immune response to the virus. The Ebola virus causes a disease called Ebola hemorrhagic fever. Symptoms begin with fever and muscle aches and progress to breathing problems, severe bleeding, kidney problems, and shock. The infection may be mild, but it can also lead to death. The vaccine used in this study is made from small parts of Ebola genetic material. It cannot cause Ebola hemorrhagic fever to develop in those who receive it.

Healthy volunteers 18 to 44 years of age may be eligible for this study. Candidates will be screened with a medical history, physical examination, and laboratory tests, and complete an "assessment of understanding" questionnaire to show that they understand the study.

Depending on their order of entry into the study, participants are assigned to receive one of three vaccine doses or placebo. The first group receives the lowest dose (2 milligram) of vaccine or placebo. If this dose is safe, then the second group receives 4 mg, and if this dose is safe, the third group receives 8 mg. Injections are given in a muscle in the upper arm. Participants receive three injections, each 4 weeks apart (on study days 0, 28, and 56).

Participants record their temperature and symptoms in a diary card for 7 days following each injection. They return to the clinic 2 to 3 days after each injection and then 2 weeks after each injection until study week 10. Additional follow-up visits are then scheduled at weeks 12, 24, 38, and 52. At each visit, participants provide a blood and urine sample for testing and have their vital signs, and lymph nodes checked, their weight measured, and their symptoms reviewed. Additional laboratory tests may be requested between visits.

Clinical Trial Description

This is a Phase I, randomized, placebo-controlled, dose-escalation study of an Ebola DNA plasmid vaccine. The hypothesis is that the vaccine will be safe for human administration and elicit immune responses to Ebola. Primary objectives are to evaluate the safety and tolerability of the investigational vaccine and the secondary objective is to evaluate immune responses. Randomization assignment will be blinded to subjects, clinical investigators and laboratory investigators. ;

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.
