Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot have taken certain medications like systemic immunosuppressive drugs or live vaccines shortly before the trial starts.

What data supports the effectiveness of the EBV gp350-Ferritin Nanoparticle Vaccine treatment for EBV infection?

Research shows that a similar EBV vaccine using gp350 on nanoparticles can produce strong immune responses in animals, blocking the virus from infecting cells. This suggests that the gp350-Ferritin Nanoparticle Vaccine might also be effective in preventing EBV infection.12345

How does the EBV gp350-Ferritin Nanoparticle Vaccine differ from other treatments for EBV infection?

The EBV gp350-Ferritin Nanoparticle Vaccine is unique because it uses a nanoparticle design to present multiple copies of the gp350 protein, which is a major target for neutralizing antibodies, potentially offering stronger protection against EBV infection compared to traditional monomeric vaccines. This approach is novel as there are currently no vaccines or treatments available for EBV infection.12678

What is the purpose of this trial?

Background:Epstein-Barr virus (EBV) causes most cases of infectious mononucleosis (mono). Up to 1 in 10 people who get mono can have fatigue that lasts more than 6 months. One out of 100 people can have severe complications. EBV is also associated with several types of cancer. Researchers want to test an EBV vaccine.Objective:To test the safety of and immune response to a new vaccine against EBV.Eligibility:Healthy adults ages 18-29Design:Participants will be screened with a medical history and physical exam. They will give a blood sample.Screening tests will be repeated during the study.Participants will get a dose of the study vaccine as an injection in a muscle in the upper arm. They will be observed for 30 to 60 minutes. Blood pressure, heart rate, breathing rate, and temperature will be checked. The injection site will be examined.Participants will get a diary card. They will write down any side effects they have after the vaccine dose, or they may use an electronic diary card. Participants will be asked to write down or enter any important medical events that may occur at any time during the study.Participants will get a vaccine dose at 2 more study visits. They will have 4 follow-up visits at different times after a vaccine dose.Participants will have 6 telephone calls in between the in-person visits. They will also have 1 telephone call 1 year after the third dose of vaccine. If possible, this visit can occur in person.Participation will last about 18 months. There is an optional in-person visit or telephone call 2 years after the third dose of vaccine.

Findings from Research

In a study of asymptomatic infants in Kisumu, Kenya, researchers found that coinfection with both EBV-1 and EBV-2 was common, which affected the antibody response, particularly resulting in lower levels of anti-gp350 IgA antibodies.
The lower levels of anti-gp350 IgA in coinfected infants suggest that these antibodies are crucial for preventing secondary infections, highlighting the need for an EBV vaccine that addresses both strains to effectively protect populations at high risk for Burkitt lymphoma.
Differences in the Epstein-Barr Virus gp350 IgA Antibody Response Are Associated With Increased Risk for Coinfection With a Second Strain of Epstein-Barr Virus.Smith, NA., Baresel, PC., Jackson, CL., et al.[2020]
Current research suggests that while a monomeric EBV gp350 vaccine reduced the incidence of infectious mononucleosis in a phase 2 trial, newer formulations like multimeric forms and nanoparticles may enhance its effectiveness.
Developing a comprehensive EBV vaccine that includes various viral proteins could potentially reduce the risk of infectious mononucleosis and associated complications, as well as EBV-related malignancies such as Hodgkin lymphoma and multiple sclerosis.
