Maze Therapeutics' MZE782 Offers Hope in Treating PKU and CKD

Maze Therapeutics Shares Encouraging Outcomes from MZE782 Trials

A groundbreaking clinical trial outcome comes from Maze Therapeutics as they report positive results regarding MZE782, an oral inhibitor targeting SLC6A19. This finding highlights the potential of MZE782 as an innovative treatment for both phenylketonuria (PKU) and chronic kidney disease (CKD). In the recent Phase 1 study conducted with healthy volunteers, the results were not just promising—they surpassed expectations.

Positive Phase 1 Results and Future Trials

During the trial, MZE782 showcased remarkable effects, notably a dose-dependent enhancement in urinary amino acid excretion. A staggering 42-fold surge in urinary phenylalanine excretion was observed—a clear indication of the drug's ability to engage effectively with the intended targets. These results lay a solid foundation for Maze Therapeutics to push forward into Phase 2 studies aimed at both PKU and CKD.

Robust Safety Profile

The trial participants reported a favorable safety profile across all dosages, with no serious adverse events noted. This level of tolerance is crucial in clinical development, especially for therapies targeting chronic conditions like PKU and CKD. The findings reinforce MZE782's potential as a safe treatment for patients struggling with these conditions.

Understanding the Study Design

The Phase 1 trial employed a randomized, double-blind, placebo-controlled design, engaging 112 healthy adult volunteers divided across various dosing cohorts. The single ascending doses (SAD) ranged from 30 to 960 mg, while multiple ascending doses (MAD) were strategically set from 120 to 240 mg, administered over seven days. The design was meticulous, aiming to confirm safety while evaluating pharmacokinetics and the drug’s pharmacodynamic effects.

Pharmacokinetics and Pharmacodynamics

MZE782 displayed a commendable pharmacokinetic profile, achieving consistent absorption rates. Significantly, participants reported a notable increase in urinary excretion levels of Phe and Gln, solidifying the drug's target engagement. The pharmacodynamics showcased a 39-fold increase in urinary Phe excretion after a single high dose, adding to the evidence that MZE782 can effectively mitigate the symptoms of PKU.

The Implications for Kidney Health

Excitingly, the initial findings suggest a potential protective effect on kidney function among CKD patients. The observed temporary dip in estimated glomerular filtration rate (eGFR) echoes effects associated with other renal therapies, hinting that MZE782 might offer long-term benefits for kidney health. Such implications could be transformative for patients with CKD, offering a complementary mechanism of action alongside existing therapies.

Plans for the Next Steps

Maze Therapeutics has laid forth its plans to progress MZE782 into two Phase 2 proof-of-concept trials. These studies will focus on observing reductions in plasma phenylalanine levels in PKU patients and proteinuria in CKD individuals. The company aims to commence these trials soon, aware that timely advancement can lead to significant breakthroughs in treatment.

Engagement with Investors

Maze will conduct a conference call detailing these promising findings, an opportunity for stakeholders to delve deeper into the results and progression of MZE782. The call aims to enhance transparency and maintain investor confidence as the company navigates future trials.
