Antibiotic Therapy in Preventing Early Infection in Patients With Multiple Myeloma Who Are Receiving Chemotherapy
RATIONALE: Giving antibiotics may be effective in preventing or controlling early infection in patients with multiple myeloma and may improve their response to chemotherapy.
PURPOSE: This randomized clinical trial is studying antibiotics to see how well they work compared to no antibiotics in preventing early infection in patients with multiple myeloma.

|Study Design:||Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Factorial Assignment
Masking: Open Label
Primary Purpose: Supportive Care
|Official Title:||Oral Antibiotic Prophylaxis of Early Infection in Multiple Myeloma|
- Proportion of patients experiencing a serious bacterial infection [ Time Frame: during the first three months of chemotherapy ] [ Designated as safety issue: No ]
|Study Start Date:||March 1997|
|Estimated Study Completion Date:||August 2015|
|Estimated Primary Completion Date:||January 2015 (Final data collection date for primary outcome measure)|
|Experimental: Ciprofloxacin or ofloxacin||
Begin oral ciprofloxacin when they start chemotherapy for multiple myeloma. Assigned treatment consists of ciprofloxacin (Cipro® 500 mg po tablet every 12 hours for two months. The patient will continue to be observed one additional month on study continuing regular myeloma chemotherapy.Drug: ofloxacin
Begin oral ofloxacin when they start chemotherapy for multiple myeloma. Assigned treatment consists of ofloxacin (500 mg po tablet every 12 hours for two months. The patient will continue to be observed one additional month on study continuing regular myeloma chemotherapy.
Begin oral Trimethoprim-sulfamethoxazole when they start chemotherapy for multiple myeloma. Assigned treatment consists of TMP-SMX (Septra® or Bactrim®) 1 DS tablet [TMP-SMX DS = 160 mg trimethoprim and 800 mg sulfamethoxazole] every 12 hours for two months..
- Evaluate whether oral antibiotic prophylaxis with co-trimoxazole (TMP-SMX) versus ciprofloxacin (CPFX) or ofloxacin versus no prophylaxis will significantly reduce rates of serious bacterial infections during the first 3 months of chemotherapy in patients with multiple myeloma.
- Determine whether antibiotic prophylaxis with TMP-SMX or CPFX (or ofloxacin) is associated with an increased incidence of nonbacterial infection or an increased rate of infection from organisms resistant to prophylactic antibiotics.
- Evaluate whether oral antibiotic prophylaxis with CPFX or ofloxacin is as effective as TMP-SMX without the associated toxic effects.
- Evaluate whether protection against early infection in multiple myeloma patients can improve their response to initial chemotherapy.
OUTLINE: This is a randomized, multicenter study. Patients are stratified by participating center. Patients are randomized to 1 of 2treatment arms.
- Arm I: Patients receive co-trimoxazole every 12 hours for 2 months followed by observation for 2 months.
- Arm II: Patients receive oral ciprofloxacin or ofloxacin every 12 hours for 2 months followed by observation for 1 month.
Patients continue their randomly assigned treatment throughout any infection in addition to any treatment needed for infection. Patients also remain on their randomly assigned treatment if chemotherapy is discontinued, changed, or delayed during the 3 month study.
Patients are followed at 6 months, 1 year, and 2 years.
PROJECTED ACCRUAL: A total of 210 patients (70 per treatment arm) will be accrued for this study.
