Study Endpoints

Primary Endpoints

Cumulative Rate of Change from Baseline in Total Kidney Volume (TKV)
Week 96

TKV will be determined from manual contours of the kidneys on 3D magnetic resonance imaging (MRI), performed by imaging specialists and verified by independent radiologists with expertise in Autosomal Dominant Polycystic Kidney Disease (ADPKD).

Number of Participants with Adverse Events (AEs)
Up to approximately 118 weeks

An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.

Secondary Endpoints

Absolute Change in Estimated Glomerular Filtration Rate (eGFR) From Baseline
Week 96
Cumulative Rate of Change from Baseline in Total Kidney Volume (TKV)
