Plain English Summary

Background and study aims
COVID-19 is a condition caused by the coronavirus (called SARS-CoV-2) that was first identified in late 2019. This virus can infect the respiratory (breathing) system. Some people do not have symptoms but can carry the virus and pass it on to others. People who have developed the condition may develop a fever and/or a continuous cough among other symptoms. This can develop into pneumonia. Pneumonia is a chest infection where the small air pockets of the lungs, called alveoli, fill with liquid and make it more difficult to breathe.

In 2020, the virus has spread to many countries around the world and neither a vaccine against the virus or specific treatment for COVID-19 has yet been developed. As of March 2020, it is advised that people minimize travel and social contact, and regularly wash their hands to reduce the spread of the virus.

Groups who are at a higher risk from infection with the virus, and therefore of developing COVID-19, include people aged over 70 years, people who have long-term health conditions (such as asthma or diabetes), people who have a weakened immune system and people who are pregnant. People in these groups, and people who might come into contact with them, can reduce this risk by following the up-to-date advice to reduce the spread of the virus.

Current knowledge about severe COVID-19 related disease suggests that patients develop an over activation of their immune system in response to the infection, which may lead to organ. Several medications licensed for patients with autoimmune disease can be used to prevent such over activation of the immune response.

This trial plans to recruit patients at an early stage in the disease course, around early infection and when the patient is starting to show mild lung complications. The purpose is to prevent organ damage and reduce the need to transfer patients to ICU and for ventilated breathing support.

Who can participate?
Adults over 18 years, strongly suspected to have a COVID-19 related disease (with or without a positive COVID-19 test), who are suitable candidates for the intervention.

What does the study involve?
Participants will be randomly allocated to receive Baricitinib in addition to standard of care, or Ravulizumab in addition to standard of care, or standard of care only. Participants will be monitored for up to 14 days with follow up visits at day 28 and day 90 after the first dosing visit.

What are the possible benefits and risks of participating?
There are no known benefits of participating in this trial.
The effect of the drugs will be analysed during the trial to make efficient decisions about efficacy and futility (e.g. lack of efficacy and risk of harm) of the trial treatments. This enables us to stop recruiting if any serious risks arise.

Where is the study run from?
Addenbrookes Hospital (UK)

When is the study starting and how long is it expected to run for?
May 2020 to May 2022

Who is funding the study?
1. Eli Lilly and Company UK Ltd.
2. Alexion Pharmaceuticals UK

Who is the main contact?
Unfortunately, this study is not recruiting public volunteers at this time. This is because the research isn’t ready for volunteers yet or the researchers are directly identifying volunteers in certain areas or hospitals. Please do not contact the research team as they will not be able to respond. For more information about COVID-19 research, visit the Be Part of Research homepage (

Study information

Scientific title

mulTi-Arm Therapeutic study in pre-ICu patients admitted with Covid-19 – Repurposed Drugs (TACTIC-R)



Study hypothesis

1. Immune modulatory therapy is superior to standard of care alone
2. Reduction of exaggerated host immune response to COVID-19 in patients at late stage 1/early stage 2 disease, reduces the composite of progression of these patients to organ failure or death and also reduces late sequelae of infection
3. Clinical and biochemical markers can be used to stratify each patient to an effective therapeutic agent and can report early on efficacy of the therapeutic approach

Ethics approval

Patient information sheet


Late stage 1/stage 2 COVID-19-related disease
COVID-19 (SARS-CoV-2 infection)


Eligible patients will be randomised to receive 1:1:1 to one of the following treatment arms (each in addition to standard of care (SoC))

Arm 1: Baricitinib oral tablets (4mg OD) in addition to standard of care
Arm 2: Ravulizumab intravenous infusion (single dose, weight-based dosing) in addition to standard of care
Arm 3: Standard of care

Randomisation will be carried out using a validated central automated web-based randomisation system.

Arm 1 Participants will be given 4mg of Baricitinib PO (2 x 2mg tables, once daily) on days 1-14 PO.
Dose adjustments for age and renal function.

Arm 2 Participants will receive Ravulizumab as a single intravenous infusion, Ravulizumab weight-based dosing regimen:
Body weight range (kg) Dose (mg)
≥ 40 to < 60 2,400
≥ 60 to < 100 2,700
≥ 100 3,000

Duration of follow up:
There will be two follow up visits at day 28 and day 90 after the first dosing visit.

Assessments will include the following:
• Discharge status
• Vaccination status (for ravulizumab arm only)
• Return to normal function status (numeric rating scale 0-10)
• Mortality status
• Adverse event reporting
• ECOG and MRC scores

Results and Publications

Publication and dissemination plan

Planned publication in a high-impact peer-reviewed journal.
The protocol (not peer reviewed) available at the study website.
Ownership of the data arising from this trial resides with the trial team and the sponsor. On completion of the trial the data will be analysed and tabulated and a Final Trial Report prepared. However, given the nature of this international pandemic, preliminary data may be reported prior to the completion the study, or if interim analyses are adequate for dissemination of critical safety or efficacy data. Any bloods done as part of the protocol or as part of observational studies will need to adhere to the pre-agreed publications policy of the TACTIC core research trial team. The sponsor will provide, if practicable, advanced notice of any publications to Alexion Pharma UK. At conclusion of the study a fully anonymised dataset will be placed in the public domain. Data sharing within a federated consortium of UK investigators across the four nations will be adopted.

IPD sharing statement:
The current data sharing plans for this study are unknown and will be available at a later date.
