What this trial studies

This study aims to assess the efficacy and safety of GDC-8264 compared to a placebo in patients undergoing non-emergent cardiac surgeries who are at moderate to high risk for acute kidney injury (AKI) and major adverse kidney events (MAKE) within 90 days post-surgery. The trial is divided into two parts to comprehensively evaluate the outcomes. Participants will be monitored for kidney function and related complications following their surgical procedures.

Who should consider this trial

Good fit: Ideal candidates include patients over 70 years old or those with specific risk factors for AKI undergoing certain types of cardiac surgery.

Not a fit: Patients with stable kidney function and no recent episodes of AKI may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the incidence of kidney injury and related complications in patients undergoing cardiac surgery.

How similar studies have performed: Other studies have explored similar interventions for preventing AKI, but the specific approach with GDC-8264 is novel.

Eligibility criteria

Inclusion Criteria:

1. One of the following non-emergent cardiac surgery types that requires cardiopulmonary bypass (CPB) to be done in one procedure rather than separate procedures: Isolated Coronary Artery Bypass Grafting (CABG); Isolated Surgical Aortic Valve Replacement (AVR), Mitral Valve Replacement (MVR), Mitral Valve repair (MVr); Combined CABG+AVR, CABG+MVR, CABG+MVr, AVR+MVR, AVR+MVr
2. At least one or at least two of the following AKI risk factors, depending on the type of surgery: age \> 70 years, history of CKD with eGFR \< 60 milliliters/ minutes/ 1.73 meter square (ml/min/1.73 m\^2) within the last 6 months, diabetes (type 1 or type 2) requiring at least one oral hypoglycemic agent or insulin, history of chronic obstructive pulmonary disease (COPD) requiring medical therapy, left ventricular ejection fraction (LVEF) \< 40%, preoperative anemia \[hemoglobin \<10 grams/deciliters (g/dL)\]

2. Need for intra-aortic balloon pump, temporary mechanical circulatory support, or extracorporeal membrane oxygenation prior to scheduled surgery

7. Hypotension or shock requiring hospital admission
8. Cardiopulmonary resuscitation
9. eGFR \< 20 mL/min/1.73 m\^2

11. History of kidney transplant or only one kidney (due to donation)
12. Renal agenesis, total nephrectomy, or partial nephrectomy of \> 50%
