What You Need to Know Before You Apply

What is the purpose of this trial?

The goal of the redePHine study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ABO-101 in participants with primary hyperoxaluria type 1 (PH1). The trial will consist of 2 Study Periods. During the first Study Period, there will be 2 parts. In Part A, adult participants will be treated with a single ascending dose to identify a recommended dose. In Part B, pediatric participants will be treated with the recommended dose. Following the first Study Period, participants will start Study Period 2, a long-term monitoring program to comply with local and national requirements.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are currently using or have used urinary oxalate lowering RNA interference (RNAi) or siRNA therapy in the past 24 months, you would not be eligible to participate.

Are You a Good Fit for This Trial?

The redePHine study is for individuals with primary hyperoxaluria type 1 (PH1), a rare condition leading to kidney stones. Adults will first receive varying doses to find the best one, then children will be treated with that dose. Participants must meet certain health criteria not specified here.

What Are the Treatments Tested in This Trial?

Interventions

• ABO-101

Trial Overview ABO-101 is being tested in this trial. It's given in two parts: adults get different amounts at first, and once the right dose is found, kids get it too. Afterward, everyone enters a long-term monitoring phase to track safety and effects over time.
