Intervention model description: Repeated measures design to register the changes before and after treatment. Non-randomized, non-blinded, multi center prospective interventional cohort trial.
Primary purpose: TREATMENT

Brief summary: The investigators are running a study to see if a special drink, called a "ketone ester", can help people with a type of kidney disease named "Autosomal Dominant Polycystic Kidney Disease" or ADPKD for short.

The investigators want to find out:

If it's easy for patients to take this drink every day for about 2 months. If it's safe and doesn't cause any problems. If it makes a difference in the size and function of the kidneys.

Who can join?

People between 16 to 70 years old who have ADPKD. Those with a certain amount of kidney size and function. People who haven't been on specific diets or lost a lot of weight recently. Women who are not breastfeeding and are using birth control. People with a body weight that is not too low or too high.

Who cannot join?

People who've been on a high-fat diet or skipped meals for a while recently. Those with other health conditions like diabetes or certain metabolic issues. Anyone who has a problem with getting an MRI scan. If participants are in another medical study right now.

The study will happen in two Belgian hospitals and is supported by the UZ Brussel's nephrology department. The investigators hope to include 20 people and start in November 2023.
