Moxifloxacin Compared With Ciprofloxacin/Amoxicillin in Treating Fever and Neutropenia in Patients With Cancer

Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
No phase specified	Supportive care	Closed	18 and over	Other	EORTC-46001 NCT00062231

Objectives

1. Compare the rates of successful response to moxifloxacin vs ciprofloxacin in combination with amoxicillin-clavulanate potassium in low-risk febrile neutropenic patients with cancer.
2. Compare the time to discharge, time to discontinuation of any antimicrobial therapy, and time to defervescence of patients treated with these regimens.
3. Compare 28-day survival of patients treated with these regimens.
4. Determine the proportion of these patients who are eligible for oral therapy and a therapeutic management including intention of early discharge.
5. Determine the medical and nonmedical reasons for continued in-hospital observation and care or for readmission of these patients.
6. Determine the accuracy of the physician's estimate of further neutropenia duration and evaluate its predictive value in these patients.
7. Validate the Multinational Association for Supportive Care in Cancer low-risk prediction rule to predict the absence of serious medical complications in the setting of oral therapy in in- and outpatients.

Entry Criteria

Disease Characteristics:

• Diagnosis of cancer with developing febrile neutropenia
  • Neutropenia defined as an absolute granulocyte count of less than 1,000/mm³, expected to fall to less than 500/mm³ within 24 hours, secondary to administration of chemotherapy and/or radiotherapy within the past 30 days
  • Fever defined as an oral temperature greater than 38.5ºC once, or 38°C or greater on 2 or more occasions at least 1 hour apart during a 12-hour period, and suspected to be due to infection



• Expected low risk of serious medical complications as predicted by a Multinational Association for Supportive Care in Cancer risk-index score of greater than 20



• No obvious signs of exit-site or tunnel intravascular catheter infection



• No known or suspected CNS infection



• No known or highly suspected bacterial, viral, or fungal infection

Prior/Concurrent Therapy:

Biologic therapy

• Not specified

Chemotherapy

• See Disease Characteristics

Endocrine therapy

• Not specified

Radiotherapy

Other

• More than 4 days since prior antibacterial agents except for the following:
  • A single (oral or parenteral therapeutic) dose after initial diagnosic work-up and within the last 8 hours
  • Low-dose cotrimoxazole (i.e., no more than 480 mg daily or 960 mg 3 times per week) prophylaxis of Pneumocystis carinii pneumonia
• More than 30 days since prior investigational drugs
• No prior randomization in this study
• No other concurrent antimicrobial agents

• No renal failure requiring hemodialysis or peritoneal dialysis

Cardiovascular

• No prior symptomatic arrhythmias
• No clinically relevant bradycardia

• No known allergy or hypersensitivity to any antibiotics in this study or other quinolones
• No signs or symptoms of severe dehydration
• No signs or symptoms of shock
• No other signs or symptoms at presentation that would necessitate IV supportive therapy

Expected Enrollment

A total of 530 patients (265 patients per treatment arm) will be accrued for this study within approximately 2 years.

Outcomes

Response as measured by International Antimicrobial Therapy Group (IATG) specific criteria at the completion of allocated treatment

Rate of complication as measured by Multinational Association for Supportive Care in Cancer (MASCC) criteria at the end of febrile neutropenic episode
Time to discharge as measured by Logrank continuously until the end of febrile neutropenic episode
Time to defervescence as measured by Logrank continuously until the end of febrile neutropenic episode
Survival status as measured by Logrank at day 28

Outline

This is a double-blind, randomized, multicenter study. Patients are stratified according to institution, underlying disease (hematologic malignancy vs other), pretreatment with no more than a single dose (yes vs no), and outpatient status at fever onset (yes vs no). Patients are randomized into 1 of 2 treatment arms.

• Arm I: Patients receive oral moxifloxacin once daily. Patients also receive oral ciprofloxacin placebo and oral amoxicillin-clavulanate potassium placebo twice daily.



• Arm II: Patients receive oral ciprofloxacin and oral amoxicillin-clavulanate potassium twice daily. Patients also receive oral moxifloxacin placebo once daily.

Patients with fever classified as not related to infection (i.e., doubtful) stop antibiotic therapy on day 3. All other patients receive antibiotics until complete resolution of infection, or until failure is determined or anticipated, for up to 28 days.

Patients are followed at 7-10 days.
