How to get involved

Patients were invited to take part in this trial if they met the following criteria:

• They were aged 16 years or older
• They had been admitted to hospital with evidence of pneumonia
• Their doctor believed they had the COVID-19 infection, and

They had an elevated marker of inflammation in the blood known as C-reactive protein (CRP).

The CATALYST trial is now closed to recruitment.

To see which hospitals particiapted in the CATALYST Trial, please see our Participating sites page.

In the UK, people from all minority ethnic groups (apart from Chinese and Mixed-race groups) are at greater risk of becoming very sick with COVID-19 when compared to the White population. We need to understand why and tackle this urgently through health research.

The National Institute of Health Research (NIHR) encourages you to learn more about research so that you can better understand what’s involved, how to find studies happening near you and how to help with COVID-19 research.

The NIHR has released a number of videos from members of minority ethnic communities asking people to come forward to help.
