Brief Summary:
To evaluate the proportion of subjects alive and free of respiratory failure (e.g. need for non-invasive or invasive mechanical ventilation, high flow oxygen, or ECMO) and free of the need for continued renal replacement therapy (RRT) on Day 28. The need for continued RRT at Day 28 will be defined as either dialysis in the past 3 days (Day 26, 27, or 28) or an eGFR on Day 28 <10 mL/min/1.73 m2.

Condition or disease Intervention/treatment Phase
COVID Severe Acute Respiratory Syndrome Sars-CoV2 Acute Kidney Injury Drug: LSALT peptide Drug: Placebo Phase 2

Detailed Description:

This is a global, multicenter, randomized, double-blind, placebo-controlled, proof of concept study of LSALT peptide as prevention of acute respiratory distress syndrome (ARDS) and acute kidney injury in patients infected with SARS-CoV-2 (COVID-19). Following screening and after establishing baseline parameters such as lung and renal function, clinical chemistries, coagulation, hematology, and urinalysis, and satisfying all inclusion and exclusion criteria, patients will be randomized to one of two blinded treatment regimens:

  1. 100 mL of 5 mg IV LSALT peptide infusion over 2 hours daily
  2. 100 mL drug-free IV saline infusion over 2 hours daily.

Thirty (30) patients will be randomized to active drug (LSALT peptide) and 30 patients will be randomized to matching placebo. Patients and, if necessary, the Legal Authorized Representative (LAR), the Investigational Staff, and the Sponsor and its representatives will not know the randomization schemata. The Pharmacist at the site will be unblinded and prepare drug/placebo for injection.

The study will have staggered enrolment in that a cohort of 6 patients will be enrolled into the study during the first wave. Further cohorts of 6 patients will be enrolled only after the Data and Safety Monitoring Board (DSMB; refer to the DSMB Charter) has assessed the adequacy of treatment based upon clinical data of the patient, target drug concentrations, and data obtained from the AB001 PK study in healthy subjects to offer recommendations to the Sponsor. In the absence of adverse events or any safety issues during the course of study, the DSMB may recommend additional cohorts of 6 patients to be studied as planned in this protocol. At no time will patients be dosed for more than 14 days of therapy. The DSMB Charter will outline all processes for changes to the protocol and protocol design prior to the first patient being enrolled into study.

Patients will be physically examined throughout the study period, including respiratory assessments. Vital signs, adverse events (AE), routine blood chemistries, coagulation, hematology, and urinalysis will be assessed throughout the study. LSALT peptide and metabolite concentrations and cytokine levels will be assessed daily at the mid-point (1 hour) and immediately at the end of the 2-hour study drug infusion. An ECG will be recorded at Baseline prior to drug therapy, Day 3, and at EOS. A chest x-ray will be obtained at Baseline and Day 3 as well as at time of clinical improvement, EOT, and EOS. Questionnaires (APACHE II, Berlin Definition, SOFA, and modified Medical Research Council Dyspnea Scale) will be assessed each morning and when indicated by the PI.

Duration of therapy will be a maximum of 14 days. Patients will be maintained on the standard of care for the treatment of COVID-19 as defined by the institutional guidelines. Co-morbidities and concomitant medications will be reviewed daily and documented in the patient's eCRF. The risk of venous thromboembolism (VTE), a potential consequence of SARS-CoV-2 infection, will be assessed daily and prophylaxis will be included as standard of care for every patient. Please refer to antithrombotic therapy in patients with COVID-19 (COVID-19 Treatment Guidelines Panel, 12-May-2020).

Experimental: LSALT
100 mL of 5 mg IV LSALT peptide infusion over 2 hours daily
Drug: LSALT peptide
LSALT, a peptide drug with the sequence NH3-LSALTPSPSWLKYKAL-COOH, binds to dipeptidase-1 (DPEP-1) but does not inhibit its biologic enzymatic activity, potentially minimizing off-target or other adverse effects. LSALT peptide inhibits leukocyte recruitment in multiple experimental disease models through the direct inhibition of leukocyte adhesion to DPEP-1 present in lungs, kidney, and liver. DPEP-1 represents a new molecular pathway for leukocyte adhesion discovered by Arch Biopartners scientists.
