E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Signed informed consent must be obtained prior to participation in the study
Participants must be able to communicate well with the investigator and to understand and comply with the requirements of the study.
Male and female patients ≥45 years at screening
Participants must weigh at least 50 kg and maximum 150 kg to participate in the study and must have a body mass index (BMI) below 40. BMI = Body weight (kg) / [Height (m)]2
At screening, vital signs should be assessed in the sitting position. Sitting vital signs should be within the the following ranges:
a. body temperature between 35.0-37.5 °C
b. blood pressure (systolic 100-160 mmHg, diastolic < 100 mmHg)
c. pulse rate (50-100/min) stable with or without medication(s) as per Investigator assessment.
6. Stable renal function with no known increase in SCr of ≥25% at screening visit compared to a previous value not older than 6 weeks. If a SCr obtained within the last 6 weeks is not available, a SCr value obtained within the last 3months can be used as the previous value (as documented by a local laboratory using standard assay methodology).
7. Non-emergent open chest cavity major cardiopulmonary bypass (CPB) surgery with expected CPB time ≥1 hour

E.4 | Principal exclusion criteria |
eGFR at screening <15 mL/min/1.73 m2 (calculated using CKD-EPI 2021 equation)
Receiving renal replacement therapy (RRT) currently or at any time within 3 months prior to screening, or scheduled to start RRT shortly after cardiac surgery.
Patients with bleeding risk at screening,or identified as such pre surgery if screening was performed earlier than Day -1). The Investigator should make this determination in consideration of the participant's medical history and/or clinical or laboratory evidence of any of the following:
History of bleeding with suspected or confirmed bleeding disorder or any other high risk for bleeding in the opinion of the investigator
Thrombocytopenia: platelet count <100x109/L
History of Platelet dysfunction:e.g. ADP induced platelet aggregation lower than 60 %
History of coagulation factor deficiency: including, but not limited to fibrinogen < 2.5-2.8 g/L or Von Willebrand factor (vWF) ≤ 50 IU/dL.
Any emergency surgeries performed less than 30 days before screening, including aortic dissection, and/or major congenital heart defects.
Schedules to undergo cardiac surgery off CPB or with hypothermic circulatory arrest
Cardiogenic shock or hemodynamic instability within four weeks prior to surgery, requiring inotropes or vasopressors or mechanical devices such as intra-aortic balloon counter-pulsation (IABP). Current or within four weeks prior to surgery, clinically significant arrhythmias associated with syncope, dyspnea or hemodynamic instability.
Have received cardiopulmonary resuscitation (CPR) within 30 days prior to cardiac surgery
Use of other investigational drugs at the time of enrollment or within 5 half lives of enrollment or until the expected PD effect has returned to baseline, whichever is longer ; or longer if required by local regulations.
Patients who are post-nephrectomy
Have ongoing sepsis or history of sepsis within the past 8 weeks or untreated diagnosed infection prior to screening visit. Sepsis is defined as presence of a confirmed pathogen, along with fever or hypothermia, and hypoperfusion or hypotension.
Recent (within the last three years) and/or recurrent history of autonomic dysfunction (e.g., recurrent episodes of fainting, palpitations, etc.).
Pregnant or nursing (lactating women)
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception while taking study treatment and until the end of study. Highly effective contraception methods include: • Total abstinence (when this is in line with the preferred and usual lifestyle of the participant. Periodic abstinence (e.g. calendar, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. • Female bilateral tubal ligation, female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or total hysterectomy at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment. • Male sterilization (at least 6 months prior to screening). For female participants on the study, the vasectomized male partner should be the sole partner for that participant. • Use of oral (estrogen and progesterone), injected, or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate < 1%), for example hormone vaginal ring or transdermal hormone contraception. In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment. If local regulations are more stringent than the contraception methods listed above to prevent pregnancy, local regulations apply and will be described in the ICF. Women are considered post-menopausal if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age-appropriate history of vasomotor symptoms). Women are considered not of child-bearing potential if they are post-menopausal or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or bilateral tubal ligation at least six weeks prior to enrollment on study. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered to be not of child-bearing potential.
Use of plasma exchange, plasmapheresis, and other extracorporeal filtration techniques within last month prior to screening or if planned to be used during or after the surgery.
