This phase II trial studies the effect of imipenem-relebactam in treating patients with cancer who have a fever due to low white blood cell counts (febrile neutropenia). In this study, imipenem-relebactam will be compared to the standard-of-care treatment (cefepime, meropenem, or piperacillin/tazobactam) for the treatment of febrile neutropenia. Imipenem-relebactam is used to treat infections. Giving imipenem-relebactam may help to control febrile neutropenia in patients with cancer.
PRIMARY OBJECTIVES: I. To evaluate the safety and tolerability of imipenem-relebactam plus vancomycin, daptomycin, or linezolid compared with SOC plus vancomycin, daptomycin or linezolid as empiric therapy in febrile neutropenic adults with cancer. OUTLINE: Patients are randomized to 1 of 2 groups. GROUP I (TREATMENT): Patients receive imipenem/cilastatin/relebactam IV over 30-60 minutes once every 6 hours (q6h) for 2 days for a minimum of 8 doses. Patients may also receive gram-positive therapy at the discretion of the primary team or emergency center physician consisting of vancomycin IV q12h or linezolid IV or orally (PO) q12h. Patients may continue to receive imipenem/cilastatin/relebactam IV over 30-60 minutes for up to 14 days if clinically indicated by the assessment of the treating physician. GROUP II (STANDARD OF CARE): Patients receive cefepime IV q8h for a minimum of 6 doses, meropenem IV q8h for a minimum of 6 doses, or piperacillin/tazobactam IV q6h for a minimum of 8 doses. Patients may also receive gram-positive therapy at the discretion of the primary team or emergency center physician consisting of vancomycin IV q12h or linezolid IV or PO q12h. Patients in both groups may receive other additional therapy (double-gram negative therapy) consisting of tobramycin IV q24h, amikacin IV q24h, ciprofloxacin IV q8h, minocycline q12h, tigecycline on days 1-2 q12h, doxycycline q12h, and/or bactrim. After at least 48 hours of gram-negative antimicrobial therapy, patients may be allowed to switch to PO or IV therapy such as linezolid PO, ampicillin, amoxicillin, amoxicillin/clavulanate PO, minocycline PO, ciprofloxacin PO, levofloxacin PO, cefpodoxime PO, trimethoprim/sulfamethoxazole PO, ceftriaxone IV, ertapenem IV, daptomycin IV and/or vancomycin IV for outpatient or home administration as clinically indicated. While in the hospital, patients undergo the collection of blood samples daily for 2 weeks, and urine samples every 2 days for up to 2 weeks. After completion of study treatment, patients are followed up at 2, 21-28, and 35-42 days.
