  Purpose
This study will treat patients who have fever and neutropenia (after cancer chemotherapy) that is possibly due to a specific bacteria (gram positive bacteria).

Febrile Neutropenia
Drug: linezolid
Drug: vancomycin
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Clinical efficacy of linezolid when administered intravenously as compared to intravenously administered vancomycin in the empiric treatment of oncology patients with febrile neutropenia with suspected gram-positive infections. [ Time Frame: 7-28 days ]

Secondary Outcome Measures:
  • Microbiologic outcome [ Time Frame: 7-28 days ]
  • Pathogen eradication (eradication rates of individual pathogens) [ Time Frame: 7-28 days ]
  • Defervescence (defined as Tmax orally or rectally) [ Time Frame: 7-28 days ]
  • Time to defervescence [ Time Frame: 7-28 days ]
  • Resolution of neutropenia (return of ANC to >500 cells/mm3) [ Time Frame: 7-28 days ]
  • Time to resolution of neutropenia [ Time Frame: 7-28 days ]
  • Mortality rate (survival at 7 days after the end of therapy) [ Time Frame: 7-28 days ]

Enrollment: 120
Study Start Date: November 2001
Study Completion Date: November 2002
Arms Assigned Interventions
Experimental: A.
Patients will be stratified according to the use of prophylactic antibiotics. Both groups may receive open-label gram-negative coverage with either ceftazidime, aztreonam, and/or aminoglycosides (gentamicin, tobramycin, amikacin). Subjects will receive study medication intravenously every 12 hours for 7 to 28 days.
Drug: linezolid
600mg every 12 hours
Other Name: Zyvox
Experimental: B. Drug: vancomycin
1gm every 12 hours. The dose of vancomycin intravenously may be adjusted for renal function, but the patient must be able to receive a 300 mL volume of intravenous fluid at the assigned dosing times of every 12 hours.
