Assessment of Efficacy and Safety of Therapy With COVID-19 Convalescent Plasma in Subjects With Severe COVID-19 (IPCO)

Phase 2

• Conditions: Severe COVID-19

• Registration Number: NCT04712344
• Lead Sponsor: University of Erlangen-Nürnberg Medical School

Brief Summary

This phase 2b clinical study will enroll adult subjects of both sexes with ARDS due to COVID-19 necessitating invasive mechanical ventilation.

Detailed Description

The primary objective of the study is the assessment of impact of immune therapy with COVID-19 convalescent plasma on severity of COVID-19.

The secondary objectives is the Impact of immune therapy with COVID-19 convalescent plasma on markers for ARDS due to severe COVID-19 infection; short-term all-cause mortality; time course of ARDS due to severe COVID-19 and assessment of safety and tolerability of immune therapy with COVID-19 convalescent plasma.

As a primary endpoint/variable we will assess change in SOFA score from Baseline Visit to Day 8.

The study design will be prospective, open-label, randomized, controlled and parallel-grouped.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Change in SOFA score from Baseline Visit	[Day 1, Visit 2] to Day 8 [Visit 9]	Change in Sequential organ failure assessment (SOFA) score predicts Predicts ICU mortality based on lab results and clinical data. SOFA includes PaO2, the Glasgow Coma Scale, Mean arterial pressure OR Administration of sedatives, Bilirubin(mg/dl), Creatinine (mg/dl) and platelets. All values are rated with a value of 1 to 4 (worst condition) and are added up gradually to a final score. The lower the SOFA score, the better is the prognosis (Maximum value 24)

Secondary Outcome Measures
