Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase 2 study is to assess the safety and efficacy of APX-115 active doses in Contrast Induced Acute Kidney Disease compared to placebo following multiple oral dosing in patients with undergoing percutaneous coronary intervention. It is anticipated that approximately 280 patients will be randomized into the study in a 1:1 ratio to 400 mg APX-115 (Isuzinaxib hydrochloride) or placebo arm.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with chronic kidney disease undergoing percutaneous coronary intervention deserve careful consideration of various clinical options to minimize the risk of contrast-induced acute kidney injury and to optimize clinical outcomes. Contrast-induced acute kidney injury (CI-AKI) is a leading cause of a hospital-acquired renal failure and has been reported to affect both the mortality and morbidity of patients receiving contrast media. Contrast-induced acute kidney injury is the third leading cause of hospital-acquired acute kidney injury and has been recognized as a serious complication of percutaneous coronary intervention (PCI), which may be associated with increased morbidity and mortality.

APX-115 is a potent small molecule inhibitor of NADPH-oxidase (NOX) isozymes developed by AptaBio Therapeutics, Inc. In-vivo study results suggest that multiple NOX isoforms may contribute to renal injury in CI-AKI model, and pan-NOX inhibition may be a new therapeutic approach for prevention of CI-AKI.

6. Women of childbearing potential or males willing and able to use at least one protocol-specified method of contraception for the duration of their enrolment.
7. Subject is aware of the investigational nature of this study and willing to comply with protocol treatments, blood tests, and other evaluations listed in the ICF.

Exclusion Criteria

1. Females who are pregnant or who are planning to become pregnant before the end of planned enrolment or who are breastfeeding.
2. Subjects who are not expected to go through PCI at the discretion of investigator or cardiologist
3. Subjects who have a history of hypersensitivity to contrast media or who cannot be administered contrast media according to investigator's discretion
4. Acute myocardial infarction within 1 month prior to Screening
5. ESRD confirmed by eGFR \< 15 mL/min/1.73 m2 at Screening.
6. Clinically significant heart disease as determined by the Investigator within 2 months prior to Screening including but not limited to any of following; cardiogenic shock, treatment requiring intra-aortic balloon pump (IABP) support, treatment with extra corporeal membrane oxygenation (ECMO), or NYHA class IV heart failure.
7. Uncontrolled treated/untreated hypertension (defined as systolic blood pressure \> 180 mmHg and/or diastolic blood pressure \> 100 mmHg, mean of measured 2 times at Screening will be permitted).
8. Known or suspected hypersensitivity to any component of the APX-115 formulation.
9. History of acute kidney injury or renal dialysis within 1 month prior to Screening and/or plan to undergo a renal dialysis during enrolment.
10. Clinically apparent liver disease as determined by the Investigator (e.g., jaundice, cholestasis, hepatic synthetic impairment, or active hepatitis) or moderate or severe hepatic impairment as determined by Child-Pugh score (Class B or C) at Screening.
11. Impaired liver function, defined as alanine aminotransferase (ALT) ≥ 2.5 times UNL or Total bilirubin \>1.5 × ULN, unless the subject has known Gilbert's syndrome.
