A new clinical trial taking place at Addenbrooke's Hospital in Cambridge will look at whether a drug usually used to treat tapeworms could help protect kidney patients from Covid-19.
Niclosamide has been re-formulated into a nasal spray for people to use twice a day.
Early research into the drug used for coronavirus patients has shown that it could stop the virus multiplying and entering cells of the upper airways.
Kidney Research UK, the Peterborough charity behind the initiative, says this is an important step.
According to the charity one in five kidney patients receiving dialysis in hospital or who have had a kidney transplant, died within four weeks if they tested positive for the virus.
The trial will see some people given a placebo drug, whilst others are given the Niclosamide.
If the trial is successful it will be rolled out across the UK
