NCT06100133

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.

Outcome Measures

Primary Outcomes (2)

  • Observance

    Objective observance (ketone body levels ≥0.8 mmol/l in ≥75% of blood measurements and ≥60% of maximal theoretic dose determined by used packages and self-report)

    56 days

  • Feasibility

    Patient reported feasibility, defined as a cohen d effect size of \< 0.5 in the ADPKD impact scale.Both targets (observance and self-reported feasibility) must be met to reach the endpoint.

    56 days

Secondary Outcomes (2)

  • Total Kidney Volume

    56 days

  • Kidney Function

    56 days
