Details and patient eligibility

About

The purpose of the present research study is to investigate the pharmacokinetics, as well as safety, tolerability and pharmacodynamics of different ascending dosing regimens of AP214 in patients undergoing cardiac surgery. AP214, the investigational drug, is being developed to potentially prevent post-surgical kidney injury after thoracic aortic aneurysm repair.

Enrollment: 42 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

2. Patients ≥ 18 years old, male or female, not of childbearing potential (postmenopausal or permanently sterilized, e.g. tubal ligation, hysterectomy, bilateral salpingectomy), regardless of ethnicity.
3. Patients undergoing CABG, valve(s), CABG/valve(s) and/or aortic root or ascending aortic aneurysm repair surgery.
4. Cleveland Clinic Renal Score ≥ 2 (higher than average risk for AKI).
5. EF ≥ 30%, evaluated within 2 months prior to screening visit.

Exclusion criteria

1. Cardiac surgery to be performed "off pump" without cardiopulmonary bypass.
2. Circulatory arrest in connection with aortic root or ascending aortic aneurysm repair surgery.
3. Confirmed or suspected endocarditis.
4. Requiring a reoperation on one of the valves within 3 months following the original valve surgical procedure.
5. Receiving Aprotinin during the trial, from Screening to Day 90.
6. Having undergone cardiovascular catheterization ≤ 48 hours prior to scheduled surgery.

19. Current abuse of alcohol or substance, according to the investigator's medical judgment.
20. Has a mental incapacity or language barriers precluding adequate understanding of trial procedures.
21. Is considered by the Investigator unsuitable to participate in the trial for any other reason, for instance due to a significant serious underlying condition.
