Be Part of Research - Trial Details - Clinical trial for the treatment of COVID-19 and COVID-like illness in primary care

Clinical trial for the treatment of COVID-19 and COVID-like illness in primary care

Medical Conditions

Reducing illness duration, complications, and possibly transmission of COVID-19 (SARS-CoV-2 infection) and other respiratory pathogens


This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


Most people with COVID-19 and COVID-like illness do not become seriously ill. Some people, however, do go on to have more serious symptoms and may even need to be admitted to hospital. The aim of this study is to investigate the effectiveness and safety of medicinal products to treat COVID-19 and COVID-like illness in adult patients across Europe. This study will investigate whether the medicinal products help patients to recover patients faster, reduce the severity of the symptoms, reduce complications that require treatment in hospital, and prevent spread to family members/housemates.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

03 Oct 2024 31 Dec 2025

Participants will be randomly allocated to receive either usual care alone or an investigational product, a placebo or a comparator product in addition to usual care.
Participants allocated to the usual care group will receive usual clinical care. Participants allocated to usual care + nitric oxide nasal spray will receive nitric oxide nasal spray (NONS) administered intranasally (into the nose) in addition to usual care, six times per day [two sprays per nostril, equivalent to 0.45 ml volume total per dose (four sprays)], for 7 days.
Participants allocated to usual care + saline nasal spray will receive a saltwater solution administered intranasally in addition to usual care, six times per day [two sprays per nostril, equivalent to 0.45 ml volume total per dose (four sprays)], for 7 days. The duration of the study for each participant is 6 months. Participants will be monitored daily for their acute symptoms for 28 days with a diary. They will receive a phone call between 28 days and 35 days in case data capture is not complete. Longer-term follow-up will be at 3 and 6 months by phone calls or electronic questionnaire. A combined throat/nose swab will be taken at the start of the study and on days 4, 7 and 14.


Patients aged 18 years or over and experiencing symptoms of a COVID-19 or COVID-like illness, presenting to primary care with COVID-19 and COVID-like-illness in Belgium, France, Germany, Ireland, Poland, Spain and the UK

The overall benefits for participants in the intervention group are related to the prevention or treatment effects of the study drug on their COVID-19 or COVID-like illness. Taking part in the study can have possible disadvantages. Participants may experience side effects from the medicinal product. There may be a brief period of discomfort from (self-)taking the combined throat/nose swabs. Taking part in the study will take up some of the time of the participant.
