mulTi-Arm Therapeutic Study in Pre-ICu Patients Admitted With Covid-19 - Experimental Drugs and Mechanisms

Summary

TACTIC-E is a randomised, parallel arm, open-label platform trial for investigating potential treatments for COVID-19 disease. While SARS-CoV infection evades detection by the immune system in the first 24 hours of infection, it ultimately produces a massive immune system response in the subgroup of people who develop severe complications. Most tissue damage following infection with COVID-19 appears to be due to a later, exaggerated, host immune response (Gralinski and Baric 2015). This leads to lung and sometimes multi-organ damage. Most people who develop these severe complications still have virus present in their respiratory tract at the time-point when the disease starts to evolve. Immune modulation in the presence of active infection has potential to cause more harm than benefit. Safety considerations when studying immune modulation strategies are paramount. This study will assess the efficacy of a novel immunomodulatory agent and a novel combination of approved agents which may protect the patient against end-organ damage and modulate the pulmonary vascular response. This study will compare the novel therapeutic agent EDP1815 and a novel combination of the approved agents dapagliflozin and ambrisentan against Standard of Care. A trial arm (UNI911) with the IMP Niclosamide was added to the protocol with one patient recruited into this arm. Following an AESI and after discussions between the funder and the Sponsor the arm was stopped.
