Summary

TACTIC-R is a randomised, parallel arm, open-label platform trial for investigating potential treatment 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 COVID19 appears to be due to a later, exaggerated, host immune response. 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. Therefore, this study proposes to assess the efficacy of immunomodulatory agents that target dysregulated immune response that drive the severe lung, and other organ, damage. The medications investigated for efficacy in this trial are Baricitinib and Ravulizumab.

Description

TACTIC-R will assess the efficacy of the immunomodulatory agents Baricitinib and Ravulizumab as potential treatments for COVID-19 disease against Standard of Care alone. These agents target the dysregulated immune response that drives the severe lung, and other organ, damage frequently seen during COVID-19 infection. This trial will compare these immunomodulatory agents to Standard of Care over a 14-day treatment period, with follow-up at 28 and 90 days. Patients will be randomised in a 1:1:1 ratio across treatments.

TACTIC-R will use a platform design with interim analysis to make efficient decisions about efficacy and futility (e.g. lack of efficacy and risk of harm) of the trial treatments. This enables the trial to stop recruiting to arms early where a clear efficacy decision can be made. It also allows for the addition of further arms.

TACTIC-R will also iterate an algorithm for use of clinical and biochemical phenotyping to:

  1. Stratify patients to therapeutic arms according to probability of efficacy
  2. Identify early indicators of failure of therapeutic strategy.

By collecting samples for genomics, transcriptomics, proteomics and immunological phenotyping, parallel studies associated with TACTIC-R will investigate host susceptibility factors for development of severe COVID-19-related disease and predictive biomarkers of response to therapeutic strategy.
