Protocol repository

In alignment with CERCLE’s steadfast commitment to transparency and upon obtaining the requisite permissions from investigators, we have been disseminating study materials specifically tailored to COVID-19 clinical research. This encompasses protocols, participant information sheets, informed consent forms, case report forms, standard operating procedures, and various other essential documents. As we continue to evolve, we aim to extend this initiative by incorporating and sharing materials pertinent to infectious diseases of epidemic and pandemic potential, as well as those addressing antimicrobial resistance (AMR) in the foreseeable future.

This material is intended to support other researchers to better understand the design and methodologies of proposed and existing studies, and to accelerate research planning by providing examples that may, where suitable, be adapted for other contexts.

If you would like to list your study on the coalition’s website, please contact us at info@cerclecoalition.org.
