Study Summary

Study Type: A multi-site, parallel group, randomized trial. Study Objectives: The objective is to evaluate safety and determine preliminary efficacy of VT-X7 (Vancomycin and Tobramycin Exchanged over 7 Days). Efficacy is evaluated as superiority of the Experimental Arm in a composite endpoint of Overall Success at 90 days, consisting of a revision prosthesis implanted at Stage 2, patient survival, absence of reoperation and absence of periprosthetic joint infection (PJI). Secondary objectives are to evaluate superiority at 365 days in a composite endpoint of Overall Success, and in separate secondary endpoints for quality of life and patient survival. The exploratory objective is to compare Experimental and Control Arms in exploratory endpoints. Follow-up: Patients will be evaluated at 90-, 180-, and 365-day follow-up visits.

Primary Outcome

Composite endpoint of Overall Success at 90 days consisting of: * Stage 2 revision prosthesis implanted; * Absence of PJI\* post-Stage 2; * Absence of reoperation\*\*\* of the affected joint pre- or post- Stage 2; and * Absence of mortality. * If clinical evidence of infection is present post-Stage 2 surgery, use the International Consensus Meeting on Musculoskeletal Infection 2018 guidelines for definitive PJI confirmation. * Reoperation includes only procedures to irrigate, debride, a
