A multicenter, prospective, non-inferiority, randomized and open clinical trial comparing levofloxacin with isoniazid in the treatment of latent tuberculosis infection in patients eligible for liver transplantation.

Patients over 18 years of age on the waiting list for liver transplantation.

Sample size: n=870 patients.


Levofloxacin treatment of latent tuberculosis infection, begun while on the waiting list for liver transplantation, is safer and not less effective than isoniazid treatment begun after transplantation when liver function is stable.

Condition Intervention Phase
Latent Tuberculosis Infection
Infection in Solid Organ Transplant Recipients
Drug: Levofloxacin
Drug: Isoniazid
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: "A Prospective, Randomized, Comparative Clinical Trial of the Efficacy and Safety of Levofloxacin Versus Isoniazid in the Treatment of Latent Tuberculosis Infection in Liver Transplant Patients".

Primary Outcome Measures:
  • Difference in incidence of tuberculosis disease [ Time Frame: 18 months of follow-up ]
    A patient will be considered as having tuberculosis when Mycobacterium tuberculosis is isolated by culture or M. Tuberculosis DNA is isolated from a representative clinical sample, organ fluid or tissue by polymerase chain reaction. Also cases of histopathologically confirmed tuberculosis (caseating granulomas with/without demonstration of acid-alcohol resistant bacillus [BAAR]) and clinically compatible presentation will be accepted. Tuberculosis will be classified as pulmonary (pulmonary parenchymal involvement), extrapulmonary (involvement of different organs to the lung) or disseminated (involvement of at least two non-contiguous organs). Cases where tuberculosis is diagnosed on the basis of clinical and/or radiology suspicion and for whom the corresponding physician has prescribed a specific treatment will not be accepted.

Secondary Outcome Measures:
  • Mortality [ Time Frame: 18 months ]
    Number of deaths of any cause

  • Toxicity [ Time Frame: During all the 18 months of follow-up ]
    Occurrence of grade 3 or 4 toxicities according to the grading (severity) scale of the National Cancer Institute Common Toxicity Criteria Version 4.0, NCI-CTC-AE v 4.0.

  • Retransplantation [ Time Frame: 18 months ]
    A new liver transplantation during the follow-up

  • Graft dysfunction [ Time Frame: 18 months ]
    Development of advanced graft fibrosis stages 3 and 4

  • Transplant rejection [ Time Frame: 18 months ]
    The occurrence of acute rejection or chronic rejection as per conventional definitions during the follow-up.

Other Outcome Measures:
  • Safety [ Time Frame: 18 months ]

    Drug tolerance will be evaluated by a clinical study interview and periodic analytical determinations which will include levels of transaminases (ALT and AST), alkaline phosphatase and gamma-GT, bilirubin, according to the study visit schedule.

    All symptoms and laboratory results will be evaluated for severity according to the grading (severity) scale of the National Cancer Institute Common Toxicity Criteria Version 3.0, NCI-CTC-AE v 3.0.

Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: levofloxacin
Levofloxacin 500 mg daily for 9 months starting on the waiting list for liver transplant
Drug: Levofloxacin
Other Names:

  • ATC Code: J01MA.
  • Pharmaceutical form: Levofloxacin 500 mg film-coated tablets
Active Comparator: Isoniazid
Isoniazid 300 mg/day for 9 months beginning after transplantation, when the "liver function is stable" and not before 3 months nor after 6 months
Drug: Isoniazid
300 mg/day for 9 months beginning after transplantation, when the "liver function is stable" and not before 3 months nor after 6 months.
Other Names:
  • Generic name: Isoniazid.
  • ATC Code: J04AC
  • Pharmaceutical form: tablets.

Detailed Description:

Primary Objective

  1. To demonstrate that the incidence of tuberculosis in patients with latent tuberculosis infection and treated with levofloxacin is not higher than that observed in patients treated with isoniazid.

    Secondary Objective

  2. To demonstrate that the efficacy of levofloxacin is not limited by adverse effects, paying particular attention to hepatotoxicity.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Liver transplantation candidates with age ≥ 18 years, no clinical or radiological evidence of active tuberculosis and negative pregnancy test (if applicable)who must meet one or more of the following criteria:

  • PPD skin test (initial or after a "booster effect") >5 mm. Alternatively, the determination may be made by the interferon gamma (IFN-g) production in PPD-stimulated lymphocytes using the Quantiferon-TB or ELISPOT assays.
  • Past history of tuberculosis not properly treated.
  • Past history of contact with a patient with active TB.
  • Chest x-ray consistent with past untreated TB (apical fibronodular lesions, calcified solitary nodule, calcified lymph nodes or pleural thickening).

The patient must give their written informed consent.

Exclusion Criteria:

  • Lack of consent to participate in the study.
  • Intolerance or allergy to levofloxacin or to isoniazid.
  • Documented contact with tuberculosis resistant to levofloxacin or to isoniazid.
  • Treatment in the previous month with drugs with potential activity against Mycobacterium tuberculosis, (especially quinolones).
