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.

Condition or disease Intervention/treatment Phase
COVID-19 Lung Infection Drug: Opaganib Drug: Placebo Phase 2 Phase 3

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.

 Drug: Placebo
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).


Outcome Measures

Secondary Outcome Measures :
  1. WHO Ordinal Scale for Clinical Improvement with a scale ranging from 8 down to 0 [ Time Frame: 14 days ]
    Compare ≥2 category improvement on the WHO Ordinal Scale for subjects taking opaganib and those on placebo, lower scores indicate improvement.

  2. Time to recovery as defined by improvement to a score of 3 or less on the WHO Ordinal Scale for Clinical Improvement with a scale ranging from 8 down to 0 [ Time Frame: 14 days ]
    Compare scores of subjects taking opaganib and those on placebo, lower scores indicate improvement.

  3. Time to low oxygen flow via nasal cannula [ Time Frame: 14 days ]
    To compare the time to low oxygen flow via nasal cannula e.g. from high oxygen flow via nasal cannula or CPAP, if high oxygen flow is not an available option between subjects taking opaganib and those on placebo.

  4. Time to discharge from hospital [ Time Frame: 14 days ]
    To compare the time to low oxygen flow via nasal cannula e.g. from high oxygen flow via nasal cannula or CPAP, if high oxygen flow is not an available option between subjects taking opaganib and those on placebo.

  5. Requiring intubation and mechanical ventilation by Day 42 [ Time Frame: 42 days ]
    To compare the proportion of patients requiring intubation and mechanical ventilation between subjects taking opaganib and those on placebo.

  6. Time to two consecutive negative swabs for SARS-CoV-2 at day 14 [ Time Frame: 14 days ]
    To compare the the time to two consecutive negative swabs for SARS-CoV-2 by PCR at Day 14 between subjects taking opaganib and those on placebo.

  7. Negative swabs for SARS-CoV-2 at day 14 [ Time Frame: 14 days ]
    To compare the proportion of patients with two consecutive negative swabs for SARS-CoV-2 by PCR at Day 14 between subjects taking opaganib and those on placebo.

  8. Fever [ Time Frame: 14 days ]
    To compare the proportion of patients, with at least one measurement of fever at baseline (defined as temperature >38.0 C [100.4 F]), who are afebrile (defined as temperature <37.2C [99 F]) at Day 14 between subjects taking opaganib and those on placebo.

  9. Mortality [ Time Frame: 28 and 42 days ]
    To compare mortality 28 and 42 days post-baseline between subjects taking opaganib and those taking placebo


Other Outcome Measures:
  1. Adverse events [ Time Frame: Up to 14 days and at the end of the 4 weeks follow-up after the end of treatment ]
    To compare the number of adverse events in patients with severe COVID-19 pneumonia between subjects taking opaganib and subjects taking placebo
