For EASi-KIDNEYTM to be able to give reliable results, it is important that people stay in the study and take their study pills (both types) every day for about three to four years, wherever possible.

The study needs to be this long so it is a definitive test of the effects of the pills on kidney disease, which can take years to progress. The results of the study could have a major impact on how kidney patients around the world are treated.

By joining the study, we are asking you to attend the local study clinic five times in about the first six months, and then attend every six months after that for a total of three to four years.

At each study appointment, a trained researcher (usually a nurse) will ask you about your health and give you a new supply of study pills. You will then have a blood sample taken to monitor your kidneys and other effects of the study pills.

At a small number of visits, we will also ask you to provide a urine sample. In addition, we may send you a questionnaire about ‘how you feel and your quality of life’ by post or email.

With your permission, we would also like to store left over blood and urine for future scientific research, including tests on your genes. This part of the study is optional, so you can still participate in the study even if you do not want your left over blood and urine stored long-term.
