S. aureus is the most common pathogen involved in prosthetic joint infection. StaphVAX® is a vaccine to prevent these infections, which conjugates the purified capsular polysaccharides of S. aureus to a carrier protein. It is currently being evaluated for future licensing. This study aims to demonstrate the safety and immunogenicity of a single dose of StaphVAX in patients who are candidates for knee or hip arthroplasty.

Condition Intervention Phase
Staphylococcal Infections Joint Prosthesis Biological: S. aureus Type 5 & 8 Capsular Polysaccharide Conjugate Biological: placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Multicenter, Randomized, Placebo-Controlled, Double-Blinded Study to Evaluate Safety and Immunogenicity of StaphVAX®, a Bivalent Staphylococcus Aureus Glycoconjugate Vaccine, in Adult Patients Receiving an Orthopaedic Prosthetic Implant
