A Study To Assess Adverse Events And Effectiveness Of IntraVenous Infusions Of ABBV-CLS-628 In Adult Participants With Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Overview

About this study

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common genetic cause of kidney disease that causes fluid-filled cysts to develop in the kidneys. The purpose of this study is to assess the safety and efficacy of ABBV-CLS-628 for the treatment of ADPKD in adult participants.

ABBV-CLS-628 is an investigational drug being developed for the treatment of ADPKD. Participants are placed in 1 of 4 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 4 chance that participants will be assigned to placebo. Around 240 adult participants with ADPKD will be enrolled at approximately 100 sites worldwide.

Participants will receive IntraVenous ABBV-CLS-628 or placebo every 4 weeks for 92 weeks. Participants will be followed for up to 15 weeks.

There may be higher treatment burden for participants in this trial compared to their standard of care . Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
