LSALT Peptide vs. Placebo to Prevent ARDS and Acute Kidney Injury in Patients Infected With SARS-CoV-2 (COVID-19)
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.
detailed description
This study is a parallel group, randomized, third-party blinded, multicenter study to assess safety and efficacy of LSALT peptide versus placebo in hospitalized patients with confirmed infection or recent confirmed infection with complications associated with 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. This study will be third-party blind with only the Pharmacist at the site unblinded for the purpose of preparing drug/placebo for injection.
Patients will be followed for safety and efficacy up to Day 28, with Day 1 being the day of randomization to assess safety. After assessing the risk of ARDS and satisfying all inclusion and exclusion criteria, the patient will be randomized to 5 mg LSALT peptide or blinded placebo to be given intravenously once daily for a maximum of 14 days. Physical and respiratory examinations, vital signs, and adverse events will be recorded throughout the study, including Day 28 (EOS). Blood chemistries, hematology, coagulation, urinalysis, ECG, SARS-CoV-2 tests, eGFR, and chest x-ray (CXR) will be assessed at Day 1 (Screening/Baseline) prior to initiation of study drug, and on Day 3, EOT, and at EOS, as well as when clinically indicated. The ECG at EOS will only be obtained if clinically indicated. An additional CXR will be obtained at time of clinical improvement. Cytokines/biomarkers and pharmacokinetics (PK) will be assessed at Day 1 (Screening/Baseline) prior to initiation of study drug, at 1 (mid-dose) and 2 hours (end of infusion) of drug therapy on Days 1, 3, EOT, and a single blood sample at EOS for cytokines/biomarkers only. Where applicable, a urinary pregnancy test will be obtained at Screening in women of childbearing potential. Questionnaires (APACHE II, SOFA) will be obtained at Baseline, Day 3, EOT, and EOS; venous blood gas (VBG) or HCO3 (bicarbonate) levels may be substituted for arterial blood gas (ABG) if it is considered standard-of-care (SOC) or in the patient's best interest, and results in comparable APACHE II and SOFA scores. Other questionnaires (Berlin Definition and modified Medical Research Council Dyspnea Scale) will be assessed at Baseline, Day 3, EOT, and EOS. IgG, IgA, and IgM antiviral antibodies will be collected at Baseline and EOS. Patients will be maintained on the SOC per institutional guidelines, including prophylaxis or treatment of VTE, throughout the study.
