Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] FIG. 1A is a diagram illustrating initiation of ARDS: neutrophil extravasation by E-selectin.

[0029] FIG. 1B is a diagram illustrating progression resulting in vascular leakage.

[0030] FIG. 2 is a diagram illustrating tocilizimab, an antibody directed against the cytokine, IL-6.

[0031] FIG. 3 is a comparison of the induction of E-selectin by IL-1β, TNF-α, and IL-10 in HDMEC (A) and HUVEC (B) cells.

[0032] FIG. 4 is a graph illustrating the determination of the soluble E-selectin (sE-selectin; sES) cut-off value for discrimination of complicating ALI/cALI in pneumonia patients.

[0033] FIG. 5 is a graph illustrating that septic patients with ARDS display higher day 0 plasma concentrations of free 2-CIFAs. Compared with subjects who never developed ARDS, those who developed ARDS within the first 6 days of sepsis have higher circulating levels of free 2-CIPA and free 2-CISA on the day of ICU admission (compared by the Wilcoxon rank-sum test). All values were included in the analyses; however, outliers higher than the y axis are not shown. Box plots show median and 25th and 75th percentile, and whiskers show minima and maxima for each condition. For the ARDS group, 9 and 11 outliers had values above 4 nM 2-CIPA or above 8 nM 2-CISA, respectively. In the non-ARDS group, there were 2 outliers with values above 8 nM 2-CISA, but none above 4 nM 2-CIPA.

[0034] FIG. 6 is a graph illustrating that, in comparison to palmitic acid (PA), exogenously added 2-CIPA increases adhesion of neutrophils to HMVEC-L.

[0035] FIG. 7 is a graph illustrating that soluble E-selectin (sE-selectin) is elevated in patients with established ARDS. Soluble E-selectin was quantified in serum from 49 patients at risk of ARDS (perforated bowel, non-ARDS progression or ARDS progression) and 10 patients who had established ARDS, using a sandwich ELISA.

[0036] FIG. 8 is a graph illustrating the effect of recombinant soluble E-selectin (E-zz) upon neutrophil respiratory burst. Freshly isolated neutrophils were pre-incubated with E-zz or recombinant soluble VCAM (V-zz) (2.5 μg/ml) for 15 minutes at 20° C. in HBSS. (A) DHR was then added at 1 μM and cells were incubated at 37° C. for 5 minutes. After 15 minutes at 37° C. in a shaking water-bath, DHR oxidation was analyzed by flow cytometry. Medium: HBSS alone. (B) Superoxide anion release measurement. After incubation with E-zz or V-zz (2.5 μg/ml) in the presence of cytochrome c, the superoxide dismutase inhibitable reduction of cytochrome c was then determined by measuring the peak absorbance between 535 and 565 nm using a Pye-Unicam scanning spectrophotometer.

[0037] FIG. 9 is a diagram illustrating the time course of soluble E-selectin (sES) according to complicating acute lung injury (ALI)/clinical status comparable to ALI (cALI). sES levels were higher in pneumonia patients with ALI/cALI than in those without ALI/cALI. sES levels decreased after commencement of treatment in the ALI/cALI group (P=0.017). However, sES levels in the non-ALI/cALI group were not significantly different at each time point (P=0.075).

[0038] FIG. 10 is a diagram illustrating the ability of tetrasaccharide and pentasaccharide (glycoside) derivatives of sialyl Le.sup.x (SLX) to reduce lung vascular injury after intrapulmonary deposition of IgG immune complexes. Oligosaccharides were infused intravenously in the indicated doses at 2.5, 3.0, and 3.5 h after intrapulmonary deposition of IgG immune complexes. Positive control values (PBS-treated rats) for permeability (A), hemorrhage (B), and MPO (C) parameters were 0.94±0.01, 0.31±0.01, and 0.64±0.02, respectively, and are shown by the stippled horizontal bar.

[0039] FIG. 11 is a diagram illustrating that pan-selectin antagonist GMI-1070 reduces soluble E-selectin levels while improving clinical outcomes in SCD vaso-occlusive crises.

[0040] FIG. 12 is a diagram illustrating that plasma soluble E-selectin levels decreased over the treatment period in all dose groups. This response was seen both in mean levels and Area-Under-Effect-Curve (AUEC). Decrease from baseline to Day 8 (at the end of 6 days of GMI-1271 given concurrently with MEC chemotherapy) was highly significant (p<0.0001) with no dose response.

[0117] The E-selectin ligand is a carbohydrate structure that contains the epitope shared by sialyl Le.sup.a and sialyl Le.sup.x. Carbohydrates are secondary gene products synthesized by enzymes known as glycosyltransferases which are the primary gene products coded for by DNA. Each glycosyltransferase adds a specific monosaccharide in a specific stereochemical linkage to a specific donor carbohydrate chain.

[0118] Non-limiting examples of suitable E-selectin antagonists include small molecules, such as nucleic acids, peptides, polypeptides, peptidomimetics, carbohydrates, glycomimetics, lipids and other organic (carbon containing) or inorganic molecules. Suitably, the E-selectin antagonist is selected from antigen-binding molecules that are immuno-interactive with a selectin, peptides that bind to the selectin and that block cell-cell adhesion, and carbohydrate or peptide mimetics of selectin ligands. In some embodiments, the E-selectin antagonist reduces the expression of a selectin gene or the level or functional activity of an expression product of that gene. For example, the E-selectin antagonist may antagonize the function of the selectin, including reducing or abrogating the activity of at least one of its ligand-binding sites.

[0119] In some embodiments, the E-selectin antagonist inhibits an activity of E-selectin or inhibits the binding of E-selectin to one or more E-selectin ligands (which in turn may inhibit a biological activity of E-selectin).

EXAMPLE

[0287] The following example is intended to be illustrative and is not meant in any way to limit the scope of the disclosure.

Prophetic Example 1: A Pilot Study to Assess the Safety, Tolerability and Efficacy of Selectin Inhibitor Compound a (GMI-1271) in Patients with COVID-19 Pneumonia

[0288] A Phase 1 prospective, interventional, single group assignment will be conducted at a single center (University of Michigan, Ann Arbor) in the United States to assess the safety, tolerability, and efficacy of Compound A in patients with COVID-19 pneumonia. Compound A is administered as an IV formulation that has been extensively tested in humans, including in healthy volunteers, patients with calf level deep vein thrombosis (DVT), and patients with acute myeloid leukemia (AML) and multiple myeloma (MM).

[0289] The primary objective of the open-label study is to evaluate if treatment with Compound A administered intravenously in addition to the best available therapy according to institutional guidelines is able to reduce the progression of acute respiratory failure, in patients with severe COVID-19 pneumonia. The primary endpoints include: (1) reduction in the progression to acute respiratory failure [Time Frame: 15 days for primary endpoint]; and (2) patients with a baseline PaO.sub.2/FiO.sub.2>=200: progression of respiratory failure is defined by: a. severe gas transfer deficit (PaO.sub.2/FiO.sub.2<200); b. persistent respiratory distress while receiving oxygen (persistent marked dyspnea, use of accessory respiratory muscles, paradoxical respiratory movements). The rate will be calculated as the proportion of patients who experienced at least one of the events above by day+15 from treatment start.

[0290] The secondary objectives include: (1) evaluating overall survival and all-cause mortality at day 15 and 28; (2) evaluating changes in the COVID ordinal outcomes scale; (3) assessing adverse events to evaluate the safety of Compound A; (4) assessing ventilator-free days, ICU-free days, oxygen, vasopressor free days; (5) evaluating changes in D-dimer; and (6) assessing the pharmacokinetics of Compound A used in this study. Exploratory objectives include: (1) examining the correlation of plasma soluble E-selectin concentrations with clinical outcomes; and (2) examining the correlations of other biomarkers of interest with clinical outcome.

[0291] 15 subjects will be enrolled in the experimental cohort to receive Compound A, with parallel data collection on non-treated patients (concurrent control cohort n=15). Inclusion/exclusion criteria will be the same between the two groups. For subjects in the experimental cohort, Compound A (20 mg/kg BID, up to a maximum dose of 2500 mg) will be IV infused over 20 minutes on days 1-7. Protocol treatment must start within 48 hours of the admitted patient requiring supplemental oxygen for documented COVID-19 pneumonia. The concurrent control cohort, not treated with Compound A, will receive the best available therapy according to institutional guidelines.

[0292] Inclusion criteria include: [0293] 1. Adults, ages 18-75 years. [0294] 2. Willing and able to provide informed consent prior to performing study procedures unless they have a legally authorized representative (LAR). [0295] 3. Documented COVID-19 pneumonia: defined as upper respiratory tract specimen (nasopharyngeal swab (NPS) or viral throat swab) positive for COVID-19 and imaging (CXR/CT scan) suggestive of COVID-19 pneumonia. [0296] 4. Confirmed coronavirus (SARS-CoV-2) infection, enrolled S 48 hours of beginning oxygen need for COVID-19+ confirmed hospital admission. [0297] 5. Currently hospitalized requiring supplemental oxygen. [0298] 6. Have severe COVID-19 according to the World Health Organization (WHO) Interim Guidance with confirmation by real-time RT-PCR assay. The enrollment criteria with one of the following: respiratory distress, respiratory rate (RR) ≥30 beats/min; oxygen saturation level less than 93% in resting state; or partial pressure of oxygen (PaO.sub.2)/oxygen concentration (FiO.sub.2) ≤300 mmHg.

[0300] 8. Willing and able to participate in all required evaluations and procedures.

[0301] Exclusion criteria include: [0302] 1. In the opinion of at least two investigators, unlikely to survive for >48 hours from screening. [0303] 2. Severe chronic respiratory disease (e.g. COPD or other) requiring supplemental oxygen and/or having required mechanical ventilation pre-COVID-19 infection. [0304] 3. Concurrent enrollment in a COVID-related interventional drug trial. Use of remdesivir, steroids, and convalescent plasma are permitted along with other standard of care therapies for COVID. [0305] 4. Currently on invasive mechanical ventilation. [0306] 5. Hypotension defined as systolic blood pressure <90 mmHg on two sequential readings at least 4 hours apart. [0307] 6.
