Treatment of COVID-19 With Opaganib in Patients With Pneumonia Requiring Oxygen

Phase 1

Withdrawn

• Conditions: COVID-19; Lung Infection
• Interventions: Drug: Opaganib

• Registration Number: NCT04502069
• Lead Sponsor: RedHill Biopharma Limited

Brief Summary

Patients diagnosed with COVID-19 infection will be offered treatment with Opaganib, 500 mg Q12 hours. Opaganib will be continuously administered for up to 2 weeks, until discharged on room air (if earlier than 2 weeks).

Detailed Description

Patients diagnosed with COVID-19 infection by nasopharyngeal viral swab, classified as severe disease, category 5, by the WHO Ordinal Scale For Clinical Improvement (who require oxygen support by high flow nasal cannula but do not require mechanical ventilation) at the time of initiation of therapy will be offered treatment with Opaganib, 500 mg Q12 hours.

Opaganib will be continuously administered for up to 2 weeks, until discharged on room air (if earlier than 2 weeks), upon voluntary withdrawal is initiated by the patient or when the physician decides that it is not in the patient's best interest to continue.

Group	Intervention	Description
Open label opaganib	Opaganib	opaganib dosed at 500 mg Q12 hours

Primary Outcome Measures

Name	Time	Method
Time to breathing room air	Up to 2 weeks	To determine the time to breathing room air (off of supplemental oxygen) after the start of opaganib treatment.
Adverse Event Grading and Coding	Up to 2 weeks	All adverse events will be graded according to the revised NCI Common Terminology Criteria for Adverse Events (NCI-CTCAE version 5.0). If an AE is not listed in the NCI-CTCAE v.5.0, then the Investigator will use the terms: mild, moderate, severe, life-threatening, or death to describe the maximum intensity of the AE.
