Please email Paige Druce if you are interested in being involved, or would like any further information about CALIPSO.
The start-up meeting was held at the ANZCA CTN workshop in August 2022. To obtain a copy of the recording, email Paige Druce.
The CALIPSO trial is a multicentre, adaptive, pragmatic, double-blind, three-arm, placebo-controlled, randomised, non-inferiority clinical trial comparing the incidence of surgical site infection after intraoperative only (Arm A), to 24 hours (Arm B) and, to 48 hours (Arm C) of IV cefazolin and placebo postoperative surgical antimicrobial prophylaxis in patients undergoing cardiac surgery.
Adult patients scheduled for cardiac surgery involving a median sternotomy.
A bolus of study drug (2g cefazolin or matched placebo) administered every 8-hours following the preoperative dose (time=0) for a total of five postoperative doses.
Incidence of surgical site infection.
Clostridioides difficile infection, other healthcare associated infections (pneumonia, blood stream infection and urinary tract infection), health economic endpoints (days alive and at home at 30, 90 and 180 days after surgery, direct health care costs, Quality of life data (EQ-5D-5L) at 180 days), microbiological impact.
Antimicrobial hypersensitivity reactions, all-cause mortality at 180 days, surgical site infections due to drug-resistant infections (defined as resistance to cefazolin) and, acute kidney injury.

The CALIPSO trial opened to recruitment in February 2023 and has since recruited 219 patients at Alfred Health, Victorian Heart Hospital, Prince Charles Hospital, Westmead Hospital, SJOG Subico, Royal Hobart Hospital, Epworth Richmond, St George Hospital and Waikato, NZ. The trial is expanding internationally with ethics processes underway for sites in South Africa, Italy and Canada.
