Quinolone Prophylaxis for the Prevention of BK Virus Infection in Kidney Transplantation: A Pilot Study

October 11, 2023 updated by: Ottawa Hospital Research Institute

Primary Research Questions:

Efficacy, safety and feasibility of a 3-month course of levofloxacin in a pilot study will be assessed.

  1. Under efficacy, this pilot will determine whether levofloxacin can decrease the incidence of BK viruria and peak urine BK viral load.
  2. Under safety, this pilot will determine the incidence of adverse events with levofloxacin.
  3. Under feasibility, this pilot will determine the number of kidney transplant patients randomized over an eight month enrolment period, adherence to the levofloxacin and frequency of patient drop-out and loss to follow-up

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

BK virus infection has emerged as a major complication in renal transplantation leading to a significant reduction in graft survival. There are currently no proven strategies to prevent or treat BK virus infection. Quinolone antibiotics, such as levofloxacin, have demonstrated activity against BK virus. The investigators hypothesize that administration of a quinolone antibiotic, when given early post-transplantation, will prevent the establishment of BK viral replication in the urine and thus prevent systemic BK virus infection. A non-randomized study in kidney transplant recipients found that patients given levofloxacin or ciprofloxacin had a significantly lower incidence of BK viremia compared to those not receiving a quinolone (4% versus 24.5%, P=0.02).

Objective: The primary objective of the full trial will be to determine if the quinolone levofloxacin decreases the occurrence of doubling creatinine, transplant failure or death in kidney transplant recipients. The aim of this pilot trial is to assess the efficacy, safety and feasibility of a 3-month course of levofloxacin in the kidney transplant population.

Results from this pilot study will provide vital information to design and conduct a large, multi-centre trial to determine if quinolone therapy decreases meaningful clinical outcomes in kidney transplantation. If levofloxacin significantly reduces BK viruria and urine viral loads in kidney transplantation it will provide important justification of biologic effect to progress to the larger trial. If the full trial shows that levofloxacin significantly reduces BK infection and improves outcomes, its use in renal transplantation will be strongly endorsed given the lack of proven therapies for this condition.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • a primary or repeat kidney transplant recipient (deceased or living donor)
  • age greater or equal to 18 years

Exclusion Criteria:

  • Unable to provide informed consent
  • Greater than 5 days post-transplantation
  • BK virus nephropathy with a previous transplant
  • History of allergic reaction to any quinolone antibiotic
  • History of quinolone associated tendonitis or tendon rupture
  • Corrected QT interval prolongation on EKG as defined by Al-Khatib

  • Pregnant or breastfeeding as safety of levofloxacin not established
  • Requires quinolone antibiotic for more than 14 days (e.g. for UTI prophylaxis)
