Brief Summary


The purpose of this Phase 3 study is to characterize the efficacy and safety of QPI-1002 for
prevention of Major Adverse Kidney Events (MAKE) in subjects who are at high risk for AKI
following cardiac surgery. The primary endpoint will be the proportion of subjects who develop
any of the components of MAKE90 (MAKE by day 90), defined as either death through day 90,
initiation of Renal Replacement Therapy (RRT) through day 90, or a ≥ 25% reduction in
estimated glomerular filtration rate based on serum cystatin C (eGFRcys) at the Day 90 visit.


• To assess the efficacy of a single intravenous (IV) infusion of QPI-1002 in preventing Major Adverse Kidney
Events (MAKE) in subjects at high risk for acute kidney injury (AKI) following cardiac surgery.
• To assess the safety and tolerability of an IV infusion of QPI-1002 in comparison to placebo when
administered to subjects at high risk for AKI following cardiac surgery.

Detailed Description

Subjects who have undergone non-emergent cardiac surgery and meeting all other eligibility criteria will berandomized 1:1 after cardiac surgery to receive a blinded single infusion of either QPI-1002 (10mg/kg) or placebo(saline). The selection of a 10 mg/kg single dose of QPI-1002 is based on the results from the previouslyconducted Phase 1 QRK.002 study in cardiac surgery subjects, the Phase 1/2 QRK.006 study in recipients of akidney transplant from deceased donors, and the demonstration of a positive benefit risk with QPI-1002 forreduction of the incidence of AKI in the Phase 2 study QRK209. Study drug will be administered via intravenousbolus approximately 4 hours ± 30 minutes after the discontinuation of cardiopulmonary bypass (CPB) pump.Study enrollment is planned not to exceed approximately 1088 subjects. Approximately 1038 subjects who haveundergone cardiac surgery will be randomized with a target of 519 subjects in each treatment group. Up to anadditional 50 subjects, adults 18 to <45 years old, may be randomized. An interim safety analysis will beconducted when approximately 50% of the subjects have been randomized and complete Day 5.Subject data will be collected at the Screening Visit (up to 28 days prior to cardiac surgery), Baseline/Day −1,Surgery and Post-Op, Day 1, 2, 3, 4, 5, 7, Day of Discharge, and Days 30, 60, and 90. Long term subject survivaland malignancy status will be obtained under a separate rollover protocol at one year post dosing.Blood samples will be obtained at protocol specific times for analysis of neutrophil gelatinase-associated lipocalin(NGAL).The study duration is 90 days. The primary endpoint will be evaluated at Day 90, with multiple secondaryendpoints, including incidence, severity and duration of AKI. Hospitalization length of stay and number of posthospitalization days at the pre-hospitalization residence endpoints will be collected through Day 90 and analyzedas specified in the Statistical Analysis Plan (SAP). Adverse events (AEs) will be collected through Day 30 andserious adverse events (SAEs) will be collected through Day 90. Long term subject survival and malignancystatus will be obtained under a separate rollover protocol at one year post dosing.Data will be locked and assessed for efficacy and safety once the

(including consent for the use and disclosure of research related health information) and are willing and able
to comply with the requirements of the study (including required study visits)
2. Adult male or female, age ≥ 18 years old
3. Have stable pre-operative renal function per Investigator assessment and no known increase in Serum
creatinine (Scr) of ≥ 0.3 mg/dL (≥ 26.4 μmol/L) during preceding 28 days as assessed by the site’s local
laboratory using standard assay methodology.
4. At risk for AKI following cardiac surgery on the basis of at least one of the following pre-operatively
assessed risk factors:
a) eGFR (defined using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) Scr formula) of

insulin usage prior to hospitalization for cardiac surgery)
c) Albuminuria defined as Urine Albumin/Creatinine ratio > 30 mcg/mg or screening urine dipstick of 1+

Note: If albuminuria is the only possible risk factor (i.e. eGFR is ≥ 60 mL/min/1.73 m2 and subject does not have a history of diabetes requiring prescribed insulin usage), a dipstick must be confirmed by urinalysis as > 30 mcg albumin/mg creatinine. If the urine albumin creatinine ratio is not available, and albuminuria is the only possible risk factor, a dipstick value of ≥ 2+ for protein or equivalent may be considered as meeting the albuminuria definition (> 30 mcg albumin/mg creatinine).

5. Undergoes non-emergent open chest cavity cardiovascular surgeries, with use of cardiopulmonary bypass
(CPB) pump:
a) Combined coronary artery bypass grafting (CABG) surgery and surgery of one or more cardiac valve
(valve(s) surgery)
b) Surgery of more than one cardiac valve (valve surgery)
c) Surgery of the aortic root or ascending part of the aorta in combination with CABG and/or valve(s)
d) If only CABG or single valve surgery, subjects are required to have at least one additional risk factor for
AKI: either two risk factors from Inclusion Criteria #4 above, OR age ≥ 70 years old, OR history of
congestive heart failure requiring hospitalization
Note: Transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR)

*Note: "Non-emergent surgery" would denote an operation that does not require prompt and immediate surgery (within a few hours or the same day) and is scheduled in advance.
