Maze Therapeutics Begins Groundbreaking Phase 2 Study for Kidney Disease
Maze Therapeutics Doses First Patient in Phase 2 HORIZON Trial
Maze Therapeutics, Inc. (Nasdaq: MAZE) has announced an important milestone in its clinical research efforts. The company has dosed the first patient in the Phase 2 clinical trial known as the HORIZON Study, which evaluates MZE829 as a potential treatment for patients suffering from APOL1 kidney disease (AKD). This innovative oral small molecule inhibitor is designed specifically to target the genetic underpinnings associated with AKD, a serious condition estimated to afflict over one million individuals in the United States.
What Is the HORIZON Study?
The HORIZON Study is a Phase 2, open-label trial featuring a basket design aimed at assessing the effectiveness of MZE829. In this study, participants with AKD who carry the high-risk APOL1 alleles (G1, G2) will be stratified based on their clinical characteristics and level of proteinuria. This differentiation allows for a nuanced understanding of MZE829’s therapeutic impact across various patient profiles, including those with related conditions such as type 2 diabetes.
The Importance of Patient Diversity
One of the distinguishing features of the HORIZON Study is its inclusive enrollment criteria, which seek to capture a wide diversity of patients. From those experiencing severe symptoms like nephrotic range proteinuria to individuals with milder manifestations, the trial represents a comprehensive approach to tackling AKD. Furthermore, it is the first of its kind to investigate the impact of a small molecule APOL1 inhibitor on diabetic patients suffering from AKD, highlighting Maze’s commitment to innovative research.
Endpoints and Evaluation Metrics
The primary goal of the HORIZON Study is to measure the reduction of proteinuria, a marker of kidney function. Specifically, researchers aim to identify the percentage of trial participants who experience a 30% or greater decrease in their urinary albumin-to-creatinine ratio (uACR) by week 12. Existing literature supports the use of uACR as a significant indicator of clinical benefit, especially in the context of hypertension and diabetes.
Looking Forward
The excitement surrounding the HORIZON Study is palpable, with Maze expecting to present proof of concept interim data as early as the first quarter of 2026. The potential implications for patients suffering from AKD are monumental, as MZE829 may usher in a new era of treatment aimed at fundamentally altering the course of this disease.
