Study of F-652 (IL-22:IgG2 Fusion Protein) in Patients With Moderate to Severe COVID-19

December 20, 2023 updated by: EVIVE Biotechnology

A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Dose-Escalation, Multicenter Study to Evaluate the Efficacy and Safety of F-652 (IL-22:IgG2 Fusion Protein) in Patients With Moderate to Severe COVID-19

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is planned to include 4 cohorts, with enrolled patients being randomized 1:1 in a blinded manner on Day 1, following screening, to F-652 or placebo as follows:

  • Cohort 1 (sentinel cohort): Four patients will receive either dose level 1 F-652 or placebo. Upon completion of sentinel, the Data Monitoring Committee will evaluate the safety and tolerability data of the sentinel patients and determine if it is acceptable to dose the remaining patients in this dosing group in Cohort 2.
  • Cohort 2: Fourteen patients will receive either dose level 1 F-652 or placebo. Upon completion of Cohort 2, the DMC will convene and review all available safety data to determine if the study can proceed to the next dose level.
  • Cohort 3 (sentinel cohort): Four patients will receive either dose level 2 F-652 or placebo. Upon completion of sentinel dosing, the DMC will evaluate the safety and tolerability data of the sentinel patients and determine if it is acceptable to dose the remaining patients in this dosing group in Cohort 4.
  • Cohort 4: Sixteen patients will receive either dose level 2 F-652 or placebo. Treatment will begin on Day 1 following randomization. Patients assigned to active drug will receive a total of 2 doses of F-652 (1 IV infusion on Day 1 and 1 IV infusion on Day 8). Patients assigned to placebo will receive identical IV infusions of placebo vehicle on Days 1 and 8. All patients will receive available supportive and antiviral therapies as standard of care. Efficacy will be assessed on Days 15 and 29. Patients will be followed for safety until Day 60.

The primary efficacy endpoint is the proportion of patients with a ≥2-point increase in the National Institute of Allergy and Infectious Diseases (NIAID) 8-point ordinal scale from baseline to Day 29.

The secondary efficacy endpoints include the proportion of patients with a ≥2-point increase in the NIAID 8-point ordinal scale from baseline to Day 15, mortality rate by Days 15 and 29, percentage of patients who have recovered and discharged from the hospital by Days 15 and 29, and percentage of patients progressed to severe/critical disease by Day 15.

The safety endpoints include all cause treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs); change from screening (baseline) in clinical symptoms and abnormal vital signs, abnormal laboratory tests; and relationship of any AEs with F-652 treatment.

The exploratory endpoints include time to negative SARS-CoV-2 PCR test from randomization; and changes in pharmacodynamic parameters.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Time Frame: Study day 1 before dose to day 29

The proportion of patients with a greater or equal 2-point change in the National Institute of Allergy and Infectious Diseases (NIAID) 8-point ordinal scale from baseline to Day 29.
