Study Arms:
- Group I (ceftolozane-tazobactam) (Type: EXPERIMENTAL): Participants receive ceftolozane-tazobactam IV over 1 hour every 8 hours for up to 14 days in the absence of disease progression or unacceptable toxicity. After at least 3 days, participants may switch to different PO or IV antibiotics at the discretion of the study doctor.
- Group II (standard of care antibiotic treatment) (Type: ACTIVE_COMPARATOR): Participants receive standard of care antibiotic treatment consisting of either cefepime IV over 30 minutes every 8 hours, meropenem IV over 30 minutes every 8 hours, or piperacillin-tazobactam IV over 1 hour every 6 hours for up to 14 days in the absence of disease progression or unacceptable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
