AKI
Brief summary
The purpose of the clinical study is to assess safety, tolerability and pharmacokinetics of RMC-035 for the prevention and treatment of acute kidney injury (AKI) in patients undergoing cardiac surgery.
Detailed description
This is a study with two parallel treatment groups where subjects are randomized to receive RMC-035 or a matching placebo in a double-blind fashion. The study will comprise of a screening visit, followed by CABG and/or valve replacement on Day 1, double-blind treatment period and a follow-up period up to Day 30.

Eligibility
Inclusion criteria
Key Inclusion Criteria: * Female and male subjects with an age ≥18 years * Subject is scheduled for non-emergent (elective) CABG and/or valve surgery (single or multiple valves) with use of cardiopulmonary bypass (CPB) * Subject has at least ONE of the following risk factors for AKI at screening: * History of LVEF \<35% for at least 3 months prior to screening assessed by either echocardiography, cardiac MRI or nuclear scan. * History of previous open chest cavity cardiac surgery with or without CPB * Confirmed diagnosis of type 2 diabetes (T2DM) at least 3 months prior to screening AND ongoing treatment with an approved anti-diabetic drug * Age ≥70 years * Documented history of heart failure NYHA class II or higher for at least 3 months or longer at screening * Documented history of previous AKI before date of screening independent of the etiology of AKI * Documented history of anemia with hemoglobin ≤ 11 g/dL (≤6.8 mmol/L) for at least 3 months prior to screening * Documented history of albuminuria, defined as UACR \>30 mg/g or \> 30 mg/24 hour in a 24-hour urine collection. * eGFR is ≤ 60 mL/min/1.73 m2 using the Chronic Kidney Disease - Epidemiology Collaboration (CKD-EPI) equation Key
Exclusion criteria
* Estimated glomerular filtration rate (eGFR) is \<30 mL/min/1.73 m2 using the Chronic Kidney Disease - Epidemiology Collaboration (CKD-EPI) equation at screening or at baseline * Subject has surgery scheduled to be performed without CPB (off-pump) * Subject has surgery scheduled for aortic dissection * Subject is scheduled for CABG and/or valve surgery combined with additional non-emergent cardiac surgeries, e.g. for atrial fibrillation ablation * Subject is scheduled to undergo trans catheter aortic valve implantation (TAVI) or trans catheter aortic valve replacement (TAVR), or single vessel off-pump surgeries or left ventricular device (LVAD) implantation * Subject has a requirement for any of the following within one week prior to surgery: defibrillator or permanent pacemaker, mechanical ventilation, IABP, LVAD, other forms of mechanical circulatory support (MCS) (Note: The prophylactic insertion of an IABP preoperatively for reasons not related to existing LV pump function is not exclusionary)

Pre-assignment details
In this study, 13 subjects were enrolled, ie agreed to participate in the study following completion of the informed consent process. However, 1 subject did not fulfill all eligibility criteria and was not randomization. Hence, 12 subjects started the study, ie were assigned to one of the treatment arms.
