Application of Daptomycin in MRSA Infected Diabetic Foot in Comparison to Vancomycin Treatment

Phase 3
Terminated
Conditions
Diabetic Foot
Interventions
Registration Number
NCT01199783
Lead Sponsor
Ruhr University of Bochum
Brief Summary

Objective of the study is to test whether Daptomycin (6 mg/kg bodyweight) is non-inferior in treatment of severe diabetic foot infections (MRSA) in comparison to antibiotic treatment with Vancomycin (effective blood-plasma concentration of 15 mg/l). In case of microbiologically confirmed gram-negative co-infection effective antibiotic treatment according to microbiologic analysis will be administered upon medical decision in both therapy groups. The study will be carried out as a randomized, open label study.

  • Sexually active females, unless surgically sterile, must be willing to use 2 forms of contraception through the end of the study. Sexually active woman must, except if they were surgically sterilized, have to use for already 30 days before first dose of study medication an effective method of pregnancy prevention. Acceptable forms of contraception for female subjects include: oral, transdermal, injectable or implanted contraceptives, intrauterine device (IUD), female condom, diaphragm with spermicide, cervical cap, absolute waiver of sexual intercourse, use of a condom by the sexual partner, or sterile sexual partner. Male subjects with partners of child-bearing potential should use barrier contraception in addition to having their partners use another method of contraception.
Exclusion Criteria
  • Osteomyelitis according to international consensus guideline (3 of 5 criteria apply for diagnosis)
  • Presence of a severe nephropathy (creatinine clearance < 30 ml/min)
  • Advanced diabetic retinopathy
  • Simultaneous participation in another study or participation in a study in the past 30 days
  • Non permissible concomitant medication e.g. therapy regimen using several antibiotics
  • Contraindication for antibiotics
  • Dialysis essential
  • Pregnancy (to be determined by pregnancy test) or unsafe contraception
  • Neutropenia

Primary Outcome Measures
NameTimeMethod
Clinical Response of the Infection at Test-of-cure (TOC) at Day 14 Post Therapy14 days

Clinical response of the infection at test-of-cure (TOC) at day 14 post therapy by doctoral's decision

For each of the patients included in the study the clinical outcome at TOC should be assessed using the following criteria:

Cure: resolution of all clinical signs and symptoms of infection and a healing wound after ≥ 5 days of therapy Improvement: resolution of ≥ 2 - but not all- clinical signs and symptoms of infection after ≥ 5 days of therapy (only used at the end of therapy) Failure: persistence or progression of baseline clinical signs and symptoms of infections after ≥ 2 days of therapy Missing: patients received therapy for less than 2 days Indeterminate: circumstances preclude classification

Duration of Treatment The duration of treatment will be evaluated as the number of inpatient and outpatient days the patient received antibiotic therapy, even if non-consecutive.

Time to Clinical Improvement If according to the patient record
