Details and patient eligibility

About

This is a Randomized, Single-blind, Multi-center, Placebo-controlled, Phase 2a clinical trial of BX-001N to prevent patients from Cardiac Surgery Associated Acute Kidney Injury (CSA-AKI) and subsequent Major Adverse Kidney Events (MAKE) in approximately 40 participants.

Full description

This study will enroll approximately 40 participants, with 16 participants randomized to Experimental Group 1, 16 participants to Experimental Group 2, and 8 participants to the Placebo Group.

Randomized participants will be hospitalized from one day prior to surgery (Baseline, Day -1) through Day 7.

Investigational product (IP) (i.e., BX-001N) will be administered intravenously at a weight-based dose as follows: The test drug will be administered three times in total. Participants in the Placebo Group will receive placebo at the same time points and in the same manner.

Follow-up visits will be conducted up to Day 90 at the study site for scheduled efficacy and safety assessments.

Enrollment: 40 estimated patients

Sex: All

Ages: 19 to 90 years old
