Trial summary

The coronavirus disease (COVID-19) emerged in late 2019 and has since been diagnosed in over a million persons worldwide. As this virus progresses, it causes an extreme and uncontrolled response from the patient's immune system accompanied by reduced oxygen flow to major organs, and subsequent ischaemic injury.

About this study

Official title: CAN REMOTE ISCHAEMIC CONDITIONING REDUCE INFLAMMATORY MARKERS IN COVID-19 PATIENTS - A MULTI-SITE, RANDOMISED PILOT STUDY

The coronavirus disease (COVID-19) emerged in late 2019 and has since been diagnosed in over a million persons worldwide. As this virus progresses, it causes an extreme and uncontrolled response from the patient's immune system accompanied by reduced oxygen flow to major organs, and subsequent ischaemic injury.

The current treatment of COVID-19 is largely supportive without any cure or vaccine available at this time. Developing new methods to reduce this heightened inflammatory response is essential to halting progression of COVID-19 in patients and reducing the severity of damage.

The cellular mechanisms seen in COVID-19 are similar to those seen in patients with sepsis. A process known as Remote Ischemic Conditioning (RIC) is an intervention which has been shown to prevent cellular injury including those associated with sepsis. Based on the evidence from studies looking at sepsis, it is anticipated the same benefit would be seen in patients diagnosed with COVID-19.

RIC is a simple, non-invasive procedure where a blood pressure cuff is applied to the arm for repeated cycles of inflating and deflating (typically 3-5 cycles of 5 minutes each). This process activates pro-survival mechanisms in the body to protect vital organs and improve the immune system. Therefore, we believe it represents an exciting strategy to protect organs against reduced blood flow and extreme immune response, as seen in COVID-19 infections.

Read the detailed description

COVID-19 has an early phase and a late, with rapid progression to ARDS (due to cytokine storm), multi-organ failure and death. Suppressing these cytokine elevations maybe a key to improved outcomes. Acute and Chronic (repeated) RIC has been shown to benefit in reducing the levels cytokines following LPS-induced sepsis in animal models (1). Furthermore, mortality was significantly reduced, following chronic RIC administration as opposed to acute RIC administration.

RIC in COVID-19 patients is a pilot, multi-centre, randomised study, designed to ascertain whether RIC decreases the severity of inflammatory markers associated with a "storm" score.

20 adult patients admitted to either The Royal Free or The Lister Hospital (Stevenage) with diagnosed COVID-19 will be enrolled into the study, of confirmed but not critical status. After enrolment, patients will be randomised (n = 10 per group) 1:1 to receive RIC or no adjunctive intervention.

RIC will consist of 3-4 cycles of cuff inflations to 200 mmHg for 5 min with deflation to 0 mmHg for another 5 min, which is automatically administered by the pre-programmed cuff. Those randomised to the control group will have the blood pressure cuff placed on the arm, but it will not be inflated. RIC will be performed daily for 15 days.

Venous blood will be collected following RIC administration (where possible) and saved for the subsequent measurement of inflammatory markers such as TNF, IL-1β, IL-6, and HMGB1 in addition to cardiac biomarkers Troponin T and NT pro terminal BNP. All biomarker analysis will occur at The Hatter Cardiovascular Institute, UCL.

The endpoint is area under the curve of inflammatory markers and cardiac biomarkers. Secondary endpoint will be the need for intensive care admission or death.

It would be our intention to use autoRIC devices (CellAegis, Canada) to ascertain whether RIC can lower the cytokine response. These devices are specifically designed, blood-pressure cuffs pre-programmed for the number of uses required by each patient; the intent being "a single patient-multiple use" cuff.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary Endpoint

    The primary outcome is to demonstrate that remote ischaemic conditioning reduces the severity of inflammatory cytokine release which are responsible for the cytokine "storm" that occurs in following COVID-19 infection.

    The endpoint is area under the curve of inflammatory markers and cardiac biomarkers.

    Measured: 12 months

Secondary outcomes (1)
  1. Secondary Endpoint

    Secondary endpoint will be the need for intensive care admission or death.
