Frequently asked questions about CAZ104

What is CAZ104 used for?

CAZ104 is an investigational small molecule being studied in healthy volunteers. It is a combination of the antibiotics avibactam and ceftazidime, and the Phase 1 trials assessed how these drugs concentrate in epithelial lining fluid and blood. CAZ104 is not approved and remains in clinical development.

Who makes CAZ104?

CAZ104 is being developed by Pfizer, Inc. (NYSE: PFE). The company sponsored two Phase 1 clinical trials of the drug in healthy volunteers in the United Kingdom.

What phase is CAZ104 in?

CAZ104 is in Phase 1 clinical development. Two Phase 1 trials have been completed, both enrolling healthy volunteers. The drug is investigational and has not been approved by regulatory authorities.

What clinical trials is CAZ104 in?

CAZ104 has been studied in two completed Phase 1 trials: NCT01395420, which assessed avibactam and ceftazidime concentrations in epithelial lining fluid and plasma, and NCT01430910, which evaluated blood levels of the two antibiotics given together and separately. Both enrolled healthy adults in the United Kingdom.

Is CAZ104 the same as avibactam and ceftazidime?

CAZ104 is a combination product containing the antibiotics avibactam and ceftazidime. The clinical trials studied the levels of these two drugs in the blood and lungs when administered together as CAZ104, as well as separately.
