COVID-19 is a new disease and therefore it is still not clear exactly how the virus affects the body and why people are affected so differently. It causes infection in the lungs and the virus can then attack blood vessels in the lungs and other organs to spark off an inflammatory process that can make a person very… Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Adult, Older adult

Study population: Participants with Covid 19 and Healthy Volunteers

Who may be able to join

  • 1. Adults ≥18 years old requiring hospital admission for COVID-19
  • 2. COVID-19 confirmed by either:
  • A positive swab (using RT-PCR)
  • OR based on a high level of clinical probability confirmed by the presence of typical symptoms and compatible radiological findings on imaging with no alternative cause for these findings identified by the treating physician.

About this study

Official title: The CASCADE Study - Measures of Complement Activation and Inflammation in Patients With Coronavirus Disease 2019

COVID-19 is a new disease and therefore it is still not clear exactly how the virus affects the body and why people are affected so differently. It causes infection in the lungs and the virus can then attack blood vessels in the lungs and other organs to spark off an inflammatory process that can make a person very ill. It also can cause damage within tiny blood vessels that makes a person's blood thicken up and stop flow in vital organs. The investigators believe complement (which is a chemical in the body which can be harmful in excess) orchestrates the inflammation and thickening of the blood that can make a person sick. The investigators now need to know which of these complement chemicals are elevated in COVID-19 and compare to healthy volunteers, and assess whether the levels are higher in people with severe lung disease. The investigators believe that if levels are increased there are special treatments that can counteract them and potentially be an effective treatment for COVID-19.

In this study the investigators will measure different parts of the inflammation process to better understand what may be causing severe disease and to see if there may be benefits from a new treatment to reduce inflammation

Read the detailed description

This study is an observational cross-sectional and cohort study to assess whether there is evidence of increased complement activation and/or LTB4 levels and other parameters of inflammation and a pro-coagulative state in adult patients hospitalised with COVID-19 compared to healthy controls and also whether these measures differ with increasing severity of respiratory failure.

Blood samples (serum and plasma) will be obtained from each participant at the time of recruitment into the trial, to assess the profile of complement activation, cytokines/ chemokines, leukotrienes (specifically leukotriene B4) and markers of coagulation and inflammation in patients with COVID-19.

Participants within the cohort study will be recruited at the point of admission or as close to it as possible. Baseline sampling will be performed at time of recruitment. There will be up to 2 additional sampling points (with not more than one sample per day) if there is any worsening of the participants respiratory failure (i.e. deteriorating from mild to moderate or moderate to severe disease).

Patients just admitted to hospital will be asked to consent for both the case control and the cohort study

Data will be collected at baseline for all participants and then again at each further sampling point for the participants within the cohort study.

Patient status will be measured at 14 days from the last point of sampling.

Questions about this trial

What is this clinical trial studying?

An observational study of Coronavirus, run by Portsmouth Hospitals NHS Trust at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complement Activation (time frame: 14 days sampling time period). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04453527, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Apr 2023.
