Ceftolozane-Tazobactam for Directed Treatment of Pseudomonas Aeruginosa Bacteremia and Pneumonia in Patients With Hematological Malignancies and Hematopoietic Stem Cell Transplantation

A Pilot Study of Ceftolozane-Tazobactam in Conjunction With Rapid Molecular Diagnosis for Directed Treatment of Pseudomonas Aeruginosa Bacteremia and Pneumonia in Patients With Hematological Malignancies and Hematopoietic Stem Cell Transplantation

This is an open-label study, where participants will be given ceftolozane-tazobactam as the primary treatment for Pseudomonas aeruginosa infections. Open-label means both the investigator and the participant will known what drug will be given. Participants will be followed for approximately 60 days. Ceftolozane-tazobactam is approved by the Food and Drug Administration (FDA) for treatment of serious bacterial infection and the investigator hypothesizes that ceftolozane/tazobactam may be effective as the primary antibiotic treatment for Pseudomonas aeruginosa infections.

Intervention / Treatment
Experimental: Ceftolozane-Tazobactam
Participants receive ceftolozane-tazobactam by injection directly into the vein (intravenously, IV) every 8 hours for 10-14 days.
Zerbaxa (ceftolozane/tazobactam) for injection is supplied as a white to yellow sterile powder for reconstitution in single-use vials; each vial contains 1 g ceftolozane (equivalent to 1.147 g of ceftolozane sulfate) and 0.5 g tazobactam (equivalent to 0.537 g of tazobactam sodium).
