COVID-19 Convalescent Plasma for the Treatment of Hospitalized Patients With Pneumonia Caused by SARS-CoV-2.

Phase 1

Completed

• Conditions: COVID-19
• Interventions: Biological: COVID-19 Convalescent Plasma

• Registration Number: NCT04397757
• Lead Sponsor: University of Pennsylvania

Brief Summary

The purpose of this study is to see if this plasma can be safely used in humans with COVID-19 and to see if it improves patients' health as compared to not using it in patients with pneumonia caused by SARS-CoV-2.

Detailed Description

This open-label, randomized, controlled, phase 1 trial will assess the safety and efficacy of convalescent plasma in severely ill, hospitalized participants with pneumonia due to COVID-19. This study will enroll adults 18 years old and older, including pregnant women.

A total of 80 eligible participants will be randomized to receive either 2 units of convalescent plasma collected from ABO-compatible donors who have recovered from COVID-19 and standard of care (treatment arm) or standard of care alone (control arm). Participants in the treatment arm will receive 2 units of convalescent plasma on Study Day 1 in addition to standard of care.

Participants will be assessed on study Day 1 (pre-dose), 30 minutes after each unit of plasma, on all Study Days while hospitalized, and Study Days 15, 22, 29, and 60. All participants will undergo a series of safety and efficacy, assessments. Blood samples will be collected on Days 1 (prior to plasma administration), 3, 8, 15, 29, and 60. Oropharyngeal or endotracheal samples will be collected on Days 1 (prior to plasma administration), 3, 5, 8, 11, and 15.

Exclusion Criteria

1. Contraindication to transfusion (e.g., severe volume overload, history of severe allergic reaction to blood products), as judged by the investigator.
2. Clinical suspicion that the etiology of acute illness (acute decompensation) is primarily due to a condition other than COVID-19
3. Receipt of other investigational therapy as a part of another clinical trial. Note: investigational therapies used as part of clinical care, (eg, remdesivir, hydroxychloroquine) are permissible.

Primary Outcome Measures

Participants With Serious Adverse Events.	Up to Study Day 29	Number of participants with at least one serious adverse events (SAEs) up to Study Day 29.
Clinical Severity Score	Up to Study Day 29	Clinical Severity Score (CSC) measured by both survival time, time to recovery (defined by reaching levels 1-3 of the WHO modified 8-Point Ordinal Severity scale), and disease course while hospitalized and is calculated based on a procedure proposed by Shaw and Fay 2016 (https://doi.org/10.1002/sim.6950). CSC ranges from 1 to 57. Higher CSC is worse outcome.; Clinical status assessment (WHO modified 8-Point Ordinal Severity scale) includes: 1. Not hospitalized, no limitations on activities.; 2. Not hospitalized, limitation on activities and/or requiring home oxygen; 3. Hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 4. Hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 5. Hospitalized, requiring supplemental oxygen; 6. Hospitalized, on non-invasive ventilation or high flow oxygen devices; 7. Hospitalized, on invasive mechanical ventilation or ECMO; 8. Death
