About this study

The purpose of this randomized, double-blind, controlled, phase 2 trial is to evaluate the efficacy of treatment with HCIP in reducing hospitalization and death prior to hospitalization among outpatient adults who have RNA detection test-confirmed COVID-19 AND have developed any symptoms of COVID-19 including but not limited to fever, cough, or other COVID associated symptoms like anosmia. Ambulatory/outpatient adults subjects 18 years of age or older, regardless of risk factors for severe illness may participate. A total of approximately 1344 eligible subjects stratified with a target goal (but not binding) of 50:50 in the <65 vs ≥ 65 age range will be randomized in a 1:1 ratio to receive either HCIP or control plasma.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • ≥ 18 years of age
  • Competent and capable to provide informed consent
  • • Positive molecular test for presence of SARS-CoV-2 in fluid collected by saliva for antigen, oropharyngeal or nasopharyngeal swab
  • Experiencing any symptoms of COVID-19 including but not limited to fever(T> 100.5º F), cough, or other COVID associated symptoms like anosmia
  • ≤ 8 days since the first symptoms of COVID-19
  • ≤ 8 days since first positive SARS-CoV-2 RNA test
  • Able and willing to comply with protocol requirements listed in the informed consent

Exclusion criteria

  • Hospitalized or expected to be hospitalized within 24 hours of enrollment
  • Psychiatric or cognitive illness or recreational drug/alcohol use that in the opinion of the principal investigator, would affect subject safety and/or compliance
  • History of prior reactions to transfusion blood products
  • Inability to complete therapy with the study product within 24 hours after enrollment
  • Receiving any treatment drug for COVID-19 within 14 days prior to screening evaluation (monoclonal antibodies, compassionate use or study trial related). Steroid treatment at any time does not affect study eligibility

Treatment and study plan

SARS-CoV-2 convalescent plasma

Biological

SARS-CoV-2 convalescent plasma (1 cup; minimum of 175 mL collected by apheresis from a volunteer who recovered from COVID-19 disease and has SARS-CoV-2 antibody titers ≥ 1:320 and after July 2021 meets FDA criteria for high titer plasma.

Other names: Human coronavirus immune plasma (HCIP)

Plasma from a volunteer donor

Biological

Plasma collected from a volunteer donor prior to January 1, 2020 will not be tested for SARS-CoV-2 antibodies. Plasma collected after December 31, 2019 will be confirmed as SARS-CoV-2 seronegative.

Primary outcomes

  1. Cumulative Number of Hospitalizations or Deaths Prior to Hospitalization

    Time frame: Up to day 28

    Cumulative Number measured as the proportion of subjects who were hospitalized or who died prior to hospitalization

  2. Cumulative Incidence of Severe Infusion Reactions

    Time frame: Up to day 28

    Cumulative incidence measured as rate per person-years experiencing treatment-related severe infusion reactions during the study period.

  3. Cumulative Incidence of Treatment-related Grade 3 or Higher Adverse Events

    Time frame: Up to day 90

    Cumulative incidence measured as rate per person-years experiencing a Grade 3 or higher.

  4. Cumulative Incidence of Treatment-related Acute Respiratory Distress Syndrome (ARDS)

    Time frame: Up to day 28

    Cumulative incidence measured as rate per person-years of treatment-related severe Acute Respiratory Distress Syndrome (ARDS) during the study period.

Secondary outcomes

  1. Serum SARS-CoV-2 Antibody Titers by Visit

    Time frame: Days 0, 14, 28 and 90

    Geometric mean Spike Receptor Binding Domain (RBD) titers at day 0, 14, 28 and 90 between the randomized arms.

Other outcomes

  1. Number of Participants With ICU Admission

    Time frame: Up to day 90

    Disease severity measured by admission to the ICU

  2. Number of Participants With Invasive Mechanical Ventilation

    Time frame: Up to day 90

    Disease severity measured by invasive mechanical ventilation

  3. Number of Participants Who Died

    Time frame: Up to day 90

    Disease severity measured by death

  4. Number of Participants With Resolved COVID-19 Symptoms at Day 14

    Time frame: Day 14

    Number of participants with resolved COVID-19 symptoms at day 14

  5. Number of Participants With Resolved COVID-19 Symptoms at Day 28

    Time frame: Day 28

    Number of participants with resolved COVID-19 symptoms at day 28

  6. Number of Participants With Resolved COVID-19 Symptoms at Day 90

    Time frame: Day 90

    Number of participants with resolved COVID-19 symptoms at day 90

  7. Impact of Convalescent Plasma on Outcome as Assessed by Change in Hospitalization Rate

    Time frame: Day 0 to Day 90

    Assess change in hospitalization rate as measured by number of hospitalizations stratified by age groups <65 and >=65

  8. Impact of Donor Antibody Titers on Hospitalization Rate of Convalescent Plasma Recipients

    Time frame: Day 0 to Day28

    Impact of donor antibody titers (high/low) will be assessed by hospitalization rate as measured by number of hospitalizations.
