An Efficacy, Safety, Tolerability, Immunogenicity, and Lot-Consistency Clinical Trial of a 6-Valent OspA-Based Lyme Disease Vaccine (VLA15)

Study Purpose

The main purpose of this clinical study is to evaluate a 6-valent OspA-based Lyme disease vaccine (VLA15) for prevention of Lyme disease within North America and Europe. Approximately 18,000 healthy participants 5 years and older will be recruited from areas with high levels of endemic Lyme disease to receive VLA15 or placebo (an inactive substance consisting of saltwater). Each participant will have about a 50% chance of receiving VLA15 and about a 50% chance of receiving placebo. A subset of participants will receive VLA15 from 3 different lots or placebo (1:1:1:3 ratio) to assess lot equivalence. Participants will receive a 3-dose primary vaccination series at about 0, 2, and 5 to 9 months and then receive a booster dose about 12 months later. Vaccination of participants will occur at a time of year such that the primary series is completed before the peak Lyme disease season followed by a booster dose just prior to the beginning of the second Lyme disease season. Comparison will be made between the Lyme disease cases of people receiving the study vaccine to those of the people who are not. This will help us determine if the study vaccine is safe and effective. If enrolled, participants will need to visit the research site at least 7 times during the study. There will also be at least 1 telephone contact. It is expected that each participant will take part in this study for up to about 2 and a half years.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Key

Inclusion Criteria:

  • - Participants who reside in areas with endemic Lyme disease and who lead lifestyles that put them at increased risk for Lyme disease.
For example, this could include, but not be limited to:
  • - Individuals who work in B burgdorferi-infected/tick-infested areas, especially those with occupations that may be associated with higher risk of exposure, such as landscaping, forestry, and wildlife and parks management.
  • - Individuals who pursue recreational activities such as hiking, camping, fishing, hunting, jogging, or gardening in such areas.
  • - Individuals who live on land plots with tree lines and come into contact with these trees regularly.
  • - Individuals who have dogs that regularly are outdoors and frequently return with attached ticks.
  • - Individuals who participate in activities in areas with tall grass, smaller wooded areas beside forests, open fields, lakesides, and riversides.
Key

Exclusion Criteria:

  • - Any diagnosis of Lyme disease within the past 3 months.
  • - Any history of Lyme carditis, neuroborreliosis, or arthritis, regardless of when diagnosed.
  • - Known tick bite within the past 4 weeks.
  • - Newly developed or unstable underlying conditions that may interfere with the assessment of Lyme disease, including but not limited to chronic arthralgia/arthritis, second/third-degree AV heart block, chronic pain syndromes, and chronic skin conditions that reduce the ability to detect cutaneous manifestations of Lyme disease.
  • - Any autoimmune condition with a manifestation (eg, arthritic and neurologic) that may interfere with the assessment of Lyme disease.
  • - Chronic systemic doxycycline or minocycline or other tetracycline class drug use for acne or any other chronic suppressive antibiotics used to treat other conditions.
