AGILE (Early Phase Platform Trial for COVID-19)

AGILE: Seamless Phase I/IIa Platform for the Rapid Evaluation of Candidates for COVID-19 Treatment


Sponsor

University of Liverpool

Enrollment

600 participants

Start Date

Jul 3, 2020

Study Type

INTERVENTIONAL

Summary

The AGILE platform master protocol allows incorporation of a range of identified and yet-to-be-identified candidates as potential treatments for adults with COVID-19 into the trial. Candidates will be added into the trial via candidate-specific trial (CST) protocols of this master protocol as appendices. Having one master protocol ensures different candidates are evaluated in the same consistent manor and opening up new trials for new candidates is more efficient. Inclusion of new candidates will be based on pre-clinical data, evidence in the clinical setting and GMP capabilities.


Eligibility

Min Age: 18 Years

Inclusion Criteria29

  • Adults (≥18 years) with laboratory-confirmed* SARS-CoV-2 infection (PCR)
