Piclidenoson for Treatment of COVID-19

Phase 2
Completed
Conditions
Coronavirus Infection
COVID-19
Interventions
Drug: Placebo
Registration Number
NCT04333472
Lead Sponsor
Can-Fite BioPharma
Brief Summary

Patients with documented moderate COVID-19 infection will be randomized 1:1 to receive piclidenoson 2 mg Q12H orally with standard supportive care (SSC - intervention arm) or placebo orally with SSC (control arm) for up to 28 days.

Detailed Description

This is a randomized, double-blind, placebo-controlled, pilot trial of piclidenoson 2 mg Q12H added to SSC, compared to placebo plus SSC, in a population of hospitalized subjects with "Moderate" or "Severe" COVID-19 per U.S. National Institutes of Health (NIH) Coronavirus Disease 2019 (COVID-19) Treatment Guidelines (2020). Subjects will be randomized according to a 1:1 ratio to one of the trial arms, and treated for up to 28 days, at the discretion of the Investigator. Piclidenoson 2 mg and placebo are supplied as matching tablets for oral administration.

Following initial diagnosis of COVID-19, and after having provided informed consent, subjects will be randomized according to 1:1 ratio to one of the trial arms on Day 0. SSC will be implemented and documented for all subjects, and maintained throughout the treatment period.

Vital signs (temperature, blood pressure, pulse rate per minute, respiratory rate per minute, oxygen saturation (SpO2), and PaO2/FiO2) of subjects will be monitored twice daily according to SSC. Parameters of clinical, respiratory, and vital status will be collected daily. Viral shedding will be assessed on a regular basis. Samples for pharmacokinetic (PK) analysis will be collected on Day 4.

Efficacy of piclidenoson will be assessed by clinical, respiratory, and virologic parameters. Safety and tolerability of piclidenoson will be assessed by adverse event (AE) monitoring, vital signs assessment, electrocardiograms (ECGs), and clinical laboratory tests (complete blood count (CBC) and extended chemistry panel). Adverse events will be graded by the Common Terminology Criteria for Adverse Events (CTCAE v5.0).
