Updated on 13 October 2022


The purpose of the trial is to compare the effectiveness and safety of 2 treatment regimens of CAM2029 (given weekly or every 2 weeks) to placebo in participants with symptomatic PLD, either isolated as in autosomal dominant PLD (ADPLD) or associated with autosomal dominant polycystic kidney disease (ADPKD).

In the Treatment Period of the trial, participants will be allocated at random to 1 of the 3 treatment arms in a 1:1:1 ratio. After completing the Treatment Period (53 weeks) participants may proceed to a 24-week open-label extension part of the trial and then only receive the same CAM2029 treatment.

The active ingredient in CAM2029, octreotide, is administered as a subcutaneous depot using Camurus' FluidCrystal® technology.
