Official Title
A Study of Liposomal Trans Crocetin, LEAF-4L6715, in Patients With Acute Respiratory Distress Syndrome Due to COVID-19, Sepsis or Other Causes
Brief Summary

This is an open label phase II study of treatment with LEAF-4L6715 in patients who experience severe acute respiratory distress syndrome (ARDS) due to COVID-19, Sepsis or other Causes. The purpose of this study is to evaluate the improvement in PaO2/FiO2 by more than 25% in patients treated with LEAF-4L6715.

Detailed Description

Patient is treated with LEAF-4L6715, a liposomal transcrocetin. The liposomal formulation
allows for a gradual release of the free drug, thereby facilitating less frequent dosing.

Pharmacokinetic assessment will be carried out to identify an optimal dose and schedule.

absolute neutrophil count (ANC) of > 1000 cells/mm3

8. Patients requiring dialysis due to renal impairment in cohort 3

Exclusion Criteria:

1. Patient is enrolled in any other therapeutic clinical trial with the same endpoints.
All observational studies or study with limited invasive methods (Pharmacokinetic
studies, monitoring of virus charges studies, biological monitoring studies ….) are
allowed

2. Patient is pregnant or breast-feeding

3. Patient has a known hypersensitivity to crocetins, LEAF-4L6715 or any of its
excipients
