Our hypothesis is that 30 days of oral levofloxacin (FDA approved antibiotic) in patients with persistent viremia (BK virus found in blood) will impair progress to BK virus induced kidney damage by significantly decreasing or eliminating BK virus in the blood.

Condition Intervention Phase
BK Viremia Drug: levofloxacin Drug: placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Effect of Fluoroquinolones on BK Viremia in the Renal Transplant Recipient, A Multi-Center Study
