Study of F-652 (IL-22:IgG2 Fusion Protein) in Patients With Moderate to Severe COVID-19
Condition: Covid19
MeSH terms: COVID-19
Intervention: F-652; Placebo
Intervention description: IL-22 fusion protein administered intravenously; Placebo administered intravenously
Phase: Phase 2
Study type: Interventional
Primary purpose: Treatment
Allocation: Randomized
Intervention model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking description: Patients will be randomized in a 1:1 ratio in a double-blind manner to receive F-652 or placebo.
An independent statistician from Medpace will generate the randomization schedule. Patients meeting eligibility criteria will be randomized on Day 1 in a 1:1 ratio to F-652 or placebo, respectively. Patients will be assigned a randomization number and treatment assignment according to the randomization schedule. This randomization schedule will be maintained by the investigative site pharmacist until it is appropriate to break the blind. The Investigator, investigative site personnel (except site-designated pharmacist and dedicated assistant), study monitors, vendors, Sponsor, and Medpace will remain blinded to treatment assignment.
Enrollment: 1.0
Sex: All
Minimum age: 18 Years
Healthy volunteers: No

Summary:

      This is an interventional, multicenter, 2-arm, parallel-group, randomized, double-blind,
      placebo controlled, dose-escalation, safety and efficacy study of F-652 treatment versus
      placebo in patients aged 18 years or older with a COVID-19 diagnosis confirmed by PCR.
      Eligible patients will have moderate to severe COVID-19 symptoms within 5 days post
      hospitalization and a positive COVID-19 testing.
