LEVOS - Levofloxacin and Rifampicin Therapy in the Treatment of OsteoArticular Prothethic Infection

Information source: Sanofi
ClinicalTrials.gov processed this data on August 23, 2015
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Infection

Intervention: Levofloxacin (HR355) and Rifampicin Therapy (Drug)

Phase: Phase 3

Status: Terminated

Sponsored by: Sanofi

Official(s) and/or principal investigator(s):
Nathalie Billon, Study Director, Affiliation: sanofi-aventis administrative office

Summary

The primary objective is: to assess the microbiological success of the combination of levofloxacin and rifampicin, administered for 32 to 37 days, as oral replacement therapy of an empirical antibiotic therapy of a maximum of 5 to 10 days given intravenously, in the treatment of OsteoArticular Prosthetic Infections (OAPI), with a two-stage revision of the prosthesis. The secondary endpoints are:

- To assess the rate of clinical failure 12 months after the reimplantation of the

prosthesis.

- To assess the joint mobility function score 12 months after the reimplantation of the

prosthesis.

- To assess the safety of the combination of levofloxacin and rifampicin.

- To investigate prognostic factors for success after the end of treatment and at 12

months after the reimplantation of the prosthesis.

Clinical Details

Official title: A National, Multicenter, Non-comparative Study Evaluating the Efficacy of the Combination of Levofloxacin (500 mg) and Rifampicin (600 or 900 mg Depending on Weight) Administered Once Daily by Oral Route, as Replacement of Empirical Antibiotic Therapy Given Intravenously With a Total Duration of 6 Weeks of the Antibiotic Therapy, in the Treatment of OsteoArticular Prosthetic Infections (OAPI), With a Two-stage Revision of the Prosthesis.

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Microbiological success defined as the percentage of patients with negative peri-operative bacteriological samples and the absence of clinical, biological or radiological signs of infection.

Secondary outcome:

Clinical failure

Joint mobility function score

Eligibility

Minimum age: 50 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion criteria:

- Osteoarticular prosthetic bacterial infection (hip or knee)

- Documented microbiological infection due to Staphylococcus aureus and/or

coagulase-negative staphylococci, susceptible to fluoroquinolones and to rifampicin with:

- For Staphylococcus aureus, a minimum of 2 positive perioperative samples is

required.

- For the coagulase-negative staphylococci, a minimum of 3 positive perioperative

samples is required. In the event of combination, there is a minimum of 2 positive perioperative samples for Staphylococcus aureus and a minimum of 3 positive perioperative samples for coagulase-negative staphylococci.

- Two-stage surgical management with: during the first operative stage: removal of the

prosthesis, large debridement, implantation or not of a spacer during the second operative stage: implantation of a new cemented prosthesis or not (If possible, without antibiotics as recommended by Sofcot (25), otherwise containing gentamicin).

- Negative urine pregnancy test for females of child-bearing age.

- A barrier contraception method throughout the duration of treatment and for the 4

weeks following the discontinuation of rifampicin for females of child-bearing age. Exclusion criteria:

- Osteoarticular prosthetic infection at more than one site.

- Osteoarticular prosthetic infection without bacteriological documentation.

- Infection due to staphylococci that are not susceptible to fluoroquinolones or

rifampicin.

- Infection not due to staphylococci.

- Absence of surgical management.

- More than 2 surgical repeats due to infection at the infected site.

- Renal impairment with creatinine clearance < 50 ml/min.

- Hepatic impairment.

- Hypersensitivity to levofloxacin, to a product in the quinolone class, to rifamycins

or to the excipients of the study products.

- A history of tendinopathy associated with a fluoroquinolone.

- Glucose-6-phosphate dehydrogenase deficiency.

- History of convulsions or epilepsy predisposing factors for the occurrence of

convulsions.

- Porphyria.

- Combination use with protease inhibitors or with delavirdine or nevirapine.

- Estrogen-progestin and progestin contraceptives.

- Patient over 65 years of age and who has received corticosteroids.

- Breast-feeding female.

- Pregnant female or female who is likely to become pregnant.

- HIV infection.

- Inflammatory rheumatism.

- Treatment with immunosuppressive agents, cardiovascular, neurological or endocrine

disease, or other medically significant disease (cancer, etc.) making the conduct of the protocol or the interpretation of the results of the trial difficult.

- A history of abuse of medicinal products or of alcohol.

- A patient who may receive treatments that are not authorized by the protocol during

the trial.

- Treatment with another product undergoing pharmaceutical development during the 4

weeks prior to inclusion in the trial.

- Patient participating in another trial.

- Patient who is allergic to gentamicin, in the event of implantation of a spacer or of

cement with gentamicin.

- Mental condition making the patient incapable of understanding the nature, objectives

and possible consequences of the trial. The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
