A Clinical Trial To Investigate The Effect Of EA-230 On Hospital Length Of Stay In Patients With Coronary Artery Disease (CAD) Undergoing Coronary Artery Bypass Grafting (CABG) Surgery. (EasyBoost)

Inclusion Criteria:

1. Patients aged ≥18 years, both male and female.
2. Patients scheduled for elective on-pump CABG with at least 3 bypasses, with or without valve replacement.
3. Willing and able to give written informed consent.

Exclusion Criteria:

1. Patients undergoing non-elective on-pump CABG (i.e., emergency surgery). Emergency surgery is defined as planned surgery within 24 hours of diagnosis.
2. Cardiogenic shock or hemodynamic instability that requires inotropes, vasopressors, or other mechanical devices, such as an intra-aortic balloon counter-pulsation (IABP), within 24 hours prior to surgery.
3. Use of a left ventricular assist device (LVAD), or intra-aortic balloon pump or other cardiac devices, within 7 days prior to surgery.
4. A requirement for any of the following within 7 days prior to surgery: defibrillator or permanent pacemaker, mechanical ventilation, IABP, LVAD, or other forms of mechanical circulatory support.
5. Required cardiopulmonary resuscitation within 14 days prior to cardiac surgery.
6. Known chronic liver disorder with Child-Pugh C classification.
7. Confirmed or treated endocarditis requiring antimicrobial or antiviral treatment within 30 days prior to surgery or other current active infection requiring antimicrobial or antiviral treatment within 14 days prior to surgery.
8. Ongoing sepsis (as defined by SEPSIS-3) within 2 weeks of screening or, in the opinion of the investigator, an untreated clinically significant infection (viral or bacterial) prior to or at Screening and before randomization.

9. Immuno-compromised patients, as self-reported or as observed in medical records, including patients:

   1. with solid organ transplantation.
   2. known to be positive for human immunodeficiency virus (HIV).
   3. that use immunosuppressive drugs or have received recent chemotherapy, at the discretion of the Investigator and including patients;

   i. with active malignancy who have undergone chemotherapy within 30 days prior to trial entry.

   ii. receiving chronic corticosteroid treatment equivalent to a prednisone dose of 10 mg or higher per day, within 30 days prior to trial entry, or an equivalent dose of another corticosteroid or any other anti-inflammatory or inflammation-suppressing medications such as interleukin blockers, methotrexate or similar therapies. Non-Steroidal Anti-Inflammatory Drugs are not exclusionary.

10. Patients with hematological disorders (known disorders from myeloid and/or lymphoid origin, leucopenia (both active and in remission)).
11. Known severe renal disease requiring dialysis, or a known estimated Glomerular Filtration Rate (eGFR) prior to admission of < 20 ml/min/1.73 m2.
12. Previous receipt of EA-230.
13. Known hypersensitivity to the IMP.
14. Use of any investigational drug within 1 month or 5 half-lives of said investigational drug (whichever is longer) prior to IMP administration in this trial. Participation in an observational clinical trial is not exclusionary.
15. Women who are pregnant, breastfeeding or planning to become pregnant during the trial or within 28 days after IMP administration (WOCBP must have a negative pregnancy test prior to entry into the trial).
16. Female patients of childbearing potential who are not willing/able to use adequate contraception and refrain from donating ova from enrolment and up to 28 days after IMP administration (contraceptive requirements are detailed in Annex 5. Contraceptive Guidance).
17. Male patients who are not willing/able to use adequate contraception (if their partners is of childbearing potential) and refrain from donating sperm from enrolment and up to 28 days after IMP administration (contraceptive requirements are detailed in Annex 5. Contraceptive Guidance).
18. Inability to personally provide written informed consent.
19. Known or suspected of not being able to comply with the trial protocol, at the discretion of the Investigator.
20. Any other condition which, in the Investigator's opinion, will interfere with completion of the trial.
21. Being an employee of the Investigator or trial site with direct involvement in the proposed trial or other studies under the direction of that Investigator or trial site or being a family member of an employee of the Investigator with direct involvement in the proposed trial.
