Official Title
Opaganib, a Sphingosine Kinase-2 (SK2) Inhibitor in COVID-19 Pneumonia: a Randomized, Double-blind, Placebo-Controlled Phase 2/3 Study, in Adult Subjects Hospitalized With Severe SARS-CoV-2 Positive Pneumonia
Brief Summary

A phase 2/3 multi-center randomized, double-blind, parallel arm, placebo- controlled study in Adult Subjects Hospitalized with Severe SARS-CoV-2 Positive Pneumonia to determine the potential of opaganib to improve and/or stabilize the clinical status of the patient.

Detailed Description

This is a phase 2/3 multi-center randomized, double-blind, parallel arm, placebo- controlled
study with an adaptive design that will utilize a futility assessment. The study is planned
be performed worldwide in up to approximately 80 clinical sites.

After informed consent is obtained, patients will enter a screening phase for no more than 3
days, to determine eligibility. Approximately 464 eligible patients will be randomized and
receive either opaganib added to standard of care, or matching placebo added to standard of
care, in a randomization ratio of 1:1. Treatment assignments will remain blinded to the
patient, investigator and hospital staff, as well as the sponsor. As the approval and/or
guidance for treating COVID-19 are evolving, for this protocol, standard of care will be
defined by the recommended schemes of treatment according to the severity of the disease,
taking into consideration regulatory approvals in one or more regions.

Study participants will receive either opaganib 2 x 250 mg capsules (500 mg) every 12 hours,
or matching placebo, in addition to standard of care (pharmacological as defined above and/or
supportive) at any given institution. Study drug will be administered every day for 14 days
(Day 1 to Day 14). All participants will be followed up for 28 days after their last dose of
study drug, which may occur at Day 14 or after premature study drug discontinuation, based
upon patient or physician determination.

Eligibility Criteria

Inclusion Criteria:

1. Adult male or female ≥18 to ≤80 years of age

2. Proven COVID-19 infection per RT-PCR assay of a pharyngeal sample (nasopharyngeal or
oropharyngeal) AND pneumonia defined as radiographic opacities on chest X-ray or CT
scan. that diagnosed COVID-19 pneumonia. Pharyngeal samples collected either at
screening or within 7-days prior to screening for the same ongoing COVID-19 pneumonia
illness are acceptable

3. The patient requires, at baseline, high flow supplemental oxygen or positive pressure
ventilation or is receiving oxygen via face mask, such as a non-rebreather or
reservoir mask, capable of delivering high concentrations of oxygen

4. Patient agrees to use appropriate methods of contraception during the study and 3
months after the last dose of study drug

5. The patient or legal representative has signed a written informed consent approved by
the IRB/Ethics Committee

Exclusion Criteria:

1. Any co-morbidity that may add risk to the treatment in the judgment of the
investigator, particularly patients with known cardiac conditions, and serious
neuropsychiatric conditions such as psychosis or major depression

2. Requiring intubation and mechanical ventilation at baseline

3. Patient has a 'Do Not Intubate' and/or 'Do Not Resuscitate' order in place

4. Oxygen saturation >95% on room air

5. Any preexisting respiratory condition that requires intermittent or continuous
ambulatory oxygen prior to hospitalization

6. Patient is, in the investigator's clinical judgement, unlikely to survive >72 hours

7. Pregnant (positive serum or urine test within 3 days prior to randomization) or
nursing women .

8. Unwillingness or inability to comply with procedures required in this protocol.

9. Corrected QT (QTc) interval on electrocardiogram (ECG) >470 ms for females or >450 ms
for males, calculated using Friedericia's formula (QTcF)

10. AST (SGOT) or ALT (SGPT) > 2.0 x upper limit of normal (ULN)

11. Total bilirubin >1.5x ULN (except where bilirubin increase is due to Gilbert's
Syndrome)

12. Serum creatinine >2.0 X ULN

13. Absolute neutrophil count <1000 cells/mm3

14. Platelet count <75,000/mm3

15. Hemoglobin <8.0 g/dL

16. Medications that are sensitive substrates, or substrates with a narrow therapeutic
range, for CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19 CYP2D6 , CYP3A4, P-gP, BCRP and
OATP1B1 should be avoided with opaganib

17. Moderate or strong inhibitors of CYP1A2, CYP3A4, CYP2D6 or P-gP or moderate to strong
inducers of CYP3A4 and CYP1A2 are prohibited

18. Currently taking warfarin, apixaban, argatroban or rivaroxaban due to drug-drug
interaction based on CYP450 metabolism

19. Current drug or alcohol abuse

20. Currently participating in a clinical study assessing pharmacological treatments,
including anti-viral studies

21. Treatment with any medication that causes QT prolongation within seven days, or 5
half-lives, whichever is longest, prior to initiation of study drug, or intention to
use them throughout the study, including but not limited to: amiodarone,
amitriptyline, citalopram dose greater than 20 mg/day, dihydroergotamine,
disopyramide, dofetilide, dronedarone, ergotamine, ibutilde, ondansetron or other
5-HT3 receptor antagonists, pimozide, procainamide, quinidine, quinine, quinolone,
