Trial Summary

What is the purpose of this trial?

This trial tests a new drug called RGLS8429 to see if it is safe and effective for people with a specific kidney disease called ADPKD. The drug is given through an injection under the skin. Researchers will check if it helps improve kidney health and function.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot have taken tolvaptan in the 28 days before joining. It's best to discuss your medications with the trial team.

Interventions

• Placebo (Drug)
• RGLS8429 (Antisense Oligonucleotide)

Trial Overview The trial tests RGLS8429's safety and its effect on ADPKD biomarkers compared to a placebo. It also looks at how it affects kidney size related to height (htTKV), its behavior in the body (pharmacokinetics), and overall kidney function.

Participant Groups

Group I: RGLS8429 Experimental Treatment 1 Intervention

The randomized,double blind part of the study (Part A) will consist of three sequential cohorts of approximately 12 subjects each randomized centrally to receive RGLS8429 or placebo by subcutaneous injection every other week (Q2W) x 7 doses (36 subjects total). * Cohort 1: first dose level of RGLS8429 or placebo * Cohort 2: second dose level of RGLS8429 or placebo * Cohort 3: third dose level of RGLS8429 or placebo

Group II: Placebo Experimental Treatment 1 Intervention

The randomized double blind part of the study (Part A) will consist of three sequential cohorts of approximately 12 subjects each randomized centrally to receive RGLS8429 or placebo by subcutaneous injection every other week (Q2W) x 7 doses (36 subjects total). * Cohort 1: first dose level of RGLS8429 or placebo * Cohort 2: second dose level of RGLS8429 or placebo * Cohort 3: third dose level of RGLS8429 or placebo

Group III: Open Label Fixed Dose RGLS8429 Experimental Treatment 1 Intervention
