This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study looks at 401 people with autosomal dominant polycystic kidney disease (ADPKD) to see how different versions of the PKD1 gene relate to patient traits like age at diagnosis and body size. Researchers are not testing any treatment—they are simply gathering information to better understand the disease. The goal is to estimate how common each gene variant group is and what clinical features go with them.

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Part A: Male and female participants aged 12 to 65 years old, inclusive, diagnosed with ADPKD who have not reached end stage kidney disease (ESKD). Part B: Male and female participants aged 12 to 65 years old, inclusive, who have completed Part A and who have genotyping results confirming an eligible non-truncating variant in PKD1 and who are at risk for rapidly progressive disease, based upon historical total kidney volume (TKV) or kidney length.

Ages

12 to 65 years

Key Inclusion Criteria: * Estimated glomerular filtration rate (eGFR) greater than or equal to (≥) 30 milliliter per minute (mL/min)/1.73 m\^2 * Willing and able to comply with scheduled visits and other study procedures * A pre-existing diagnosis of ADPKD as defined in the protocol Key Exclusion Criteria: * History of kidney disease other than ADPKD that in the opinion of the investigator would independently impact the natural history of ADPKD * History of solid organ or bone marrow transplantation or nephrectomy * Ongoing renal replacement therapy or planning to start renal replacement therapy less than or equal to (≤)12 months from the Genotyping Visit in Part A Other protocol defined Inclusion/Exclusion criteria will apply.
