Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 2a study of glycolate oxidase inhibitor LLX-424 in patients with a history of kidney stones. Eligible subjects with a history of kidney stones will be randomized to receive study drug (LLX-424 or placebo) for 8 weeks.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 2a, randomized, double-blind, placebo-controlled study designed to assess the safety, tolerability, PK, and PD effects of LLX-424 in patients with a history of kidney stones.

Following completion of screening procedures, on Study Day 1, eligible subjects will be randomized in a 2:1 ratio to receive either LLX-424 or matching placebo, respectively.

An outpatient safety Follow-up Visit will be scheduled on Day 63 or 7 days after the last dose (end of study visit).
