About this study

Official title: A Randomized, Open-Label, Single Center Clinical Trial to Assess the Efficacy and Safety of Convalescent Plasma to Hospitalized Adult COVID-19 Patients as Adjunctive Therapy to Reduce the Need for ICU Admission: Co-CLARITY Trial

This protocol provides access to investigational convalescent plasma for hospitalized patients with COVID-19. Following provision of informed consent, patients will be administered around 500 mL of convalescent plasma obtained from an individual who has recovered from a documented SARS-CoV-2 infection. The study aims to evaluate the efficacy and safety of anti-SARS-CoV-2 convalescent plasma as adjunctive therapy in preventing disease progression (prevention of ICU admission) among hospitalized patients with COVID-19. Safety outcomes include serious adverse events judged to be related to convalescent plasma. Other information which will be collected includes patient demographics and clinical data which includes quick SOFA scores, ventilator-free days, ICU-free days, dialysis-free days and 28-day mortality.

Read the detailed description

This is a phase 3, randomized, non-placebo controlled, open-label, single-center clinical trial which will assess the efficacy and safety of anti-SARS-CoV-2 convalescent plasma given from the 3rd to 14th day of illness after the onset of symptoms in preventing ICU admission among hospitalized COVID-19 patients compared to standard of care. Consecutive patients with COVID-19 admitted to the UP Philippine General Hospital will be offered participation into the study. Patients in the intervention group will receive one dose of type-specific anti-SARS-CoV-2 convalescent plasma (500 mL collected by whole blood donation or standard pheresis at the UP-PGH blood bank from a volunteer who recovered from COVID-19). The primary safety endpoints include serious adverse events judged to be related to convalescent plasma. The study also aims to compare anti-SARS-CoV-2 antibody titers and rates, levels, and duration of SARS-CoV-2 RNA in nasopharyngeal swabs using RT-PCR between the intervention and control groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of serious adverse events

    Cumulative incidence of serious adverse events (transfusion-related acute lung injury, transfusion associated circulatory overload, transfusion related infection and anaphylaxis/severe allergic reactions) during the study period

    Measured: 28 days from enrollment

Secondary outcomes (12)
  1. Quick SOFA (qSOFA) score

    Quick Sequential Organ Failure Assessment (qSOFA) scores of study participants within 28 days from enrollment. The qSOFA score is a rapid bedside clinical score used to identify patients with suspected infection that are at a greater risk for a poor outcome. Minimum score is 0 and maximum score is 3. A higher score is associated with higher risk for in-hospital mortality.

    Measured: 28 days from enrollment

  2. Cardiopulmonary arrest

    Total number of patients experiencing cardiopulmonary arrest

    Measured: 28 days from enrollment

  3. ICU mortality

    Total number of deaths among patients admitted to the ICU

    Measured: 28 days from enrollment

  4. ICU length of stay

    Total number of days patients were admitted to the ICU

    Measured: 28 days from enrollment

  5. Hospital mortality

    Total number of deaths among study participants

    Measured: 28 days from enrollment

  6. Hospital length of stay

    Total number of days patients were admitted to the hospital

    Measured: 28 days from enrollment

  7. Dialysis-free days

    Days without dialysis within 28 days from enrollment

    Measured: 28 days from enrollment

  8. Vasopressor-free days

    Days without vasopressors within 28 days from enrollment

    Measured: 28 days from enrollment

  9. ICU-free days

    Days without need for ICU admission within 28 days from enrollment

    Measured: 28 days from enrollment

  10. 28-day mortality

    Total number of patient deaths within 28 days from enrollment

    Measured: 28 days from enrollment

  11. Anti-SARS-CoV-2 antibody titers

    Anti-SARS-CoV-2 IgG antibody titers

    Measured: days 0, 1, 7 and 14 of enrollment

  12. SARS-CoV-2 RNA by RT-PCR

    Levels of SARS-CoV-2 RNA in nasopharyngeal swabs (or other specimen types as available) using RT-PCR

    Measured: days 0, 1, 7 and 14 of enrollment

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Anti-SARS-CoV-2 convalescent plasma in people with Covid19, run by University of the Philippines at 1 site in Philippines.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 24 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Philippines. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Limited enrolment (unable to achieve target sample size)). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of serious adverse events (time frame: 28 days from enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 May 2022.
