About this trial

The proposed clinical trial aims to assess if a year of treatment with a glucagon-like peptide 1 receptor agonist, a medication approved for weight management that also improves the body's response to glucose and insulin, can slow kidney growth in adults with autosomal dominant polycystic kidney disease who are overweight or obese. The study will also evaluate changes in abdominal fat and kidney metabolism using cutting-edge images techniques. Blood and urine samples will provide further insight into biological changes that may be linked to the benefits of the intervention, while ensuring careful monitoring of safety and tolerability.

Trial outcomes

Primary outcomes

1

Change in height-Adjusted Total kidney volume

To assess kidney growth,height-adjusted total kidney volume will be measured by magnetic resonance imaging at baseline and 12 months to determine annual percent change.

Time frame
Baseline, 12-months

Secondary outcomes

1

Change in body weight

Change in body weight over the 12-month period will be measured using a calibrated digital scale.

Time frame
Baseline, 12-months
2

Change in abdominal adiposity

Abdominal adiposity (subcutaneous, visceral, and total) will be assessed by magnetic resonance imaging.

Time frame
Baseline, 12-months
3

Change in adiponectin (circulating)

Venous blood samples will be analyzed for this mechanistic biomarker

Time frame
Baseline, 6-months, 12-months
4

Change in leptin (circulating)

Venous blood samples will be analyzed for this mechanistic biomarker

Time frame
Baseline, 6-months, 12-months

Other outcomes

1

Change in renal blood flow

Phase contrast magentic resonance imaging will be used to measure change in renal blood flow

Time frame
Baseline, 12-months
2

Safety (adverse events)

Number of participants with treatment-related adverse events in each group as evaluated by the DSMB

Time frame
12 months
3

Adherence

Compliance will be assessed by cross-checking the following sources and comparing these to the expected use: (1) drug accountability information; (2) counting returned trial product, visual inspection of pens; and (3) discussion with participants.

Time frame
12 months
4

Tolerability (dropout due to adverse events)

Subject dropout due to treatment-emergent adverse events

Time frame
12 months
