Patients will be followed for safety and efficacy up to Day 28 (EOS), with Day 1 being the day of randomization of study drug administered at least 1 hour prior to induction of anesthesia.\n\nA total of 240 patients will be included in the study, 120 patients each will be randomized to LSALT peptide or placebo. This study will be double-blinded with only the pharmacist at the site unblinded for the purpose of preparing drug/placebo for injection.\n\nAll subjects will undergo tests during the Screening period (window days -14 to Day 1). After satisfying all inclusion and exclusion criteria, the patient will be randomized equally to the following study arms:\n\n* LSALT peptide 10 mg IV administered over 1 hour twice daily, every 12 ± 1hour, for 5 days\n* Placebo IV administered over 1 hour twice daily, every 12 ± 1 hour, for 5 days\n\nStudy treatment will be initiated pre-operatively on Day 1 and continued for 5 days. Physical examinations, vital signs and urine output will be recorded daily throughout the treatment period and on days 6 and 7. Adverse events will be recorded daily throughout the treatment period, on Days 6, 7, and 28 EOS (Day 28). Kidney function (serum creatinine, serum cystatin C, and BUN), clinical laboratory tests, and other biomarkers will be assessed at baseline (prior to initiation of study drug) and monitored daily throughout the treatment period, on Days 6, 7, and EOS (Day 28). All patients will be maintained on the standard of care (SOC) as per institutional guidelines. Thus, SOC will be followed in each patient with the addition of LSALT peptide or placebo.\n\nSubjects will be followed until EOS (Day 28 ± 3 days) to assess renal function as discussed above.\n\nAn independent Data and Safety Monitoring Board (DSMB) will evaluate patients on a continuing basis for primarily safety assessments. Per the DSMB Charter, the DSMB will meet at least monthly if not more frequently based upon enrollment throughout the study period.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.

A WCBP is defined as a female who is biologically capable of becoming pregnant. A medically acceptable method of birth control includes intrauterine devices in place for at least 3 months, surgical sterilization, or the implant. In patients who are not sexually active, abstinence is an acceptable form of birth control and urine will be tested per protocol. Women who are of nonchild-bearing potential, i.e., post-menopause, must have this condition captured in their medical history. Pregnant women and nursing mothers are excluded from this study.\n5.
