COVID-19 Convalescent Plasma for Mechanically Ventilated Population

Phase 1

Completed

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

• Registration Number: NCT04388527
• 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 can improve patients' health when they are sick with COVID-19.

Detailed Description

This open-label, single arm, phase 1 trial will assess the safety and efficacy of convalescent plasma in severely ill, mechanically ventilated participants with pneumonia due to COVID-19. This study will enroll adults 18 years old and older, including pregnant women. A total of 50 eligible participants will receive 2 units of convalescent plasma collected from ABO-compatible donors who have recovered from COVID-19. Participants will receive convalescent plasma on Study Day 1 in addition to standard of care. Participants will be assessed daily while hospitalized and then on Study Days 15, 22, 29, and 60. All participants will undergo a series of safety, efficacy, and laboratory assessments. Blood samples will be collected on Days 1 (prior to plasma administration), 3, 5, 8, 11, 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. a. Note: investigational therapies used as part of clinical care, (eg, remdesivir, hydroxychloroquine) are permissible.
