A Guardian investigation has revealed a cancer patient has died and three others have been hospitalised after they were administered unlicensed versions of chemotherapy by Sciensus, Britain’s biggest medicines delivery business.
The company is paid millions of pounds each year by the NHS to provide healthcare at home and transport vital drugs and medical items to about 200,000 patients with conditions including cancer, heart disease, diabetes, dementia and HIV.
We would like to speak to people about their experiences with Sciensus. Do you have any concerns?
