Arch Biopartners' phase II trial for LSALT peptide, targeting cardiac surgery-associated acute kidney injury (CS-AKI), has begun patient recruitment and dosing in Canada. The trial, an international, multi-center, randomized, double-blind, placebo-controlled study, aims to evaluate the percentage of subjects with acute kidney injury within seven days following on-pump cardiac surgery. LSALT peptide, Arch Biopartners' lead drug candidate, targets the dipeptidase-1 (DPEP1) pathway to prevent ischemia-reperfusion injury.
