COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Primary outcome [1] 322955 0
The purpose of this study is to:
• Measure the amount of GS-6207 in participants with normal or severely impaired renal (kidney) function that gets into the blood stream and how long it takes to get rid of it.
Timepoint [1] 322955 0
Blood draws will occur at the following time points:
Days 1, 2, 4, 6, 8, 15, 22, 29, 36, 43, 50
Secondary outcome [1] 380359 0
To evaluate the safety and tolerability of GS-6207 single dose administration in participants with normal or severely impaired renal function. This is assessed by adverse event capture and physical examinations as required.
Timepoint [1] 380359 0
A symptom driven physical assesment and adverse event collection will occur at the following time-points:
Days 1, 2, 3, 4, 5, 6, 7, 8, 15, 22, 29, 36, 43, 50

Brief summary
Medicines are cleared from the body in different ways. Some medicines are mainly cleared from the body by the kidneys. When the kidneys work less well, they are no longer able to clear those medicines as fast. This can lead to a build-up of medicine in the body, unless smaller or less frequent doses are used.

Research suggests the kidneys are not very important in clearing GS-6207 from the body. The study team wants to confirm this by giving a single dose of GS-6207 to two groups of participants: adults with normal kidney function; and adults with severely reduced kidney function. The amount of GS-6207 in blood and urine after dosing will be measured, and the results of the two groups will then be compared.

The study will also collect information about how safe and well-tolerated GS-6207 is in adults with normal and severely reduced kidney function.
