Maze Therapeutics Reports Second Quarter 2025 Financial Results and Recent Highlights

MZE782 Phase 1 Trial in Healthy Volunteers to Provide Proof of Mechanism Data for Phenylketonuria (PKU) and Chronic Kidney Disease (CKD) Expected in Q3 2025

MZE829 Phase 2 HORIZON Trial Actively Enrolling Patients with APOL1-Mediated Kidney Disease; Initial Data Expected in Q1 2026

Strong Balance Sheet with $264.5 Million in Cash and Cash Equivalents, Expected to Provide Cash Runway into H2 2027

SOUTH SAN FRANCISCO, Calif., Aug. 12, 2025 (GLOBE NEWSWIRE) -- Maze Therapeutics, Inc. (NASDAQ:MAZE), a clinical-stage biopharmaceutical company developing small molecule precision medicines for patients with kidney and metabolic diseases, today reported financial results for the second quarter ended June 30, 2025, highlighting recent progress and business updates.

"With two clinical-stage programs advancing, Maze continues to execute with focus and discipline," said Jason Coloma, Ph.D., chief executive officer of Maze. "We remain on track to report key mechanistic biomarker data from our Phase 1 study of MZE782 in Q3, a significant milestone toward initiating Phase 2 trials in PKU and CKD. In addition, we continue to enroll our Phase 2 HORIZON trial of MZE829 in APOL1-mediated kidney disease, keeping us on track for an initial proof-of-concept readout in Q1 2026. With a strong balance sheet and cash runway into the second half of 2027, we're well-positioned to deliver meaningful impact for patients and value for shareholders."

Program Progress and Anticipated Milestones

MZE829 for APOL1-Mediated Kidney Disease (AMKD)

MZE829 is an oral, small molecule APOL1 inhibitor that Maze is advancing as a potential treatment for patients with AMKD, a subset of CKD estimated to affect over one million people in the United States alone.

• Maze continues to enroll patients in the Phase 2 HORIZON trial of MZE829. The trial includes a broad population of patients with AMKD, including those with diabetes, those with non-diabetic kidney disease, and patients with severe focal segmental glomerulosclerosis (FSGS).
  
  
• Maze expects to announce initial proof-of-concept data from the Phase 2 HORIZON trial in the first quarter of 2026.
  
  

MZE782 in CKD and Phenylketonuria (PKU)

MZE782 is an oral, small molecule targeting the solute transporter, SLC6A19, with potential to be a first-in-class treatment for the approximately five million U.S. patients with CKD who inadequately respond to currently available CKD therapies, as well as potential to be a best-in-class therapy for patients with PKU, an inherited metabolic disorder.

• MZE782 is currently being evaluated in a Phase 1 clinical trial in healthy volunteers.
  
  
• Maze expects to report initial data, including biomarker and proof-of-mechanism results relevant for both indications, in the third quarter of 2025.
  
  
• Based on Phase 1 results, Maze plans to initiate two separate Phase 2 clinical trials of MZE782 in CKD and PKU in 2026.
  
  

Second Quarter 2025 Financial Results

Cash Position: Cash and cash equivalents were $264.5 million as of June 30, 2025, compared to $196.8 million as of December 31, 2024. Maze expects that its current cash and cash equivalents will fund operations into the second half of 2027.

License Revenue: No license revenue was recognized during the three and six months ended June 30, 2025. License revenue was $165.0 million for the three and six months ended June 30, 2024. License revenue recognized in 2024 primarily reflects the receipt of an upfront payment of $150.0 million pursuant to the exclusive license agreement with Shionogi & Co., Ltd. (Shionogi) for the rights to MZE001, an investigational oral glycogen synthase 1 (GYS1) inhibitor that aims to address Pompe disease by limiting disease-causing glycogen buildup. License revenue in 2024 also included the receipt of an upfront payment of $15.0 million pursuant to an exclusive license agreement with Trace Neuroscience, Inc. (Trace) for the rights to a discovery research program targeting UNC13A for the treatment of amyotrophic lateral sclerosis.

Research & Development (R&D) Expenses: R&D expenses for the three and six months ended June 30, 2025, were $28.1 million and $55.7 million, respectively, and $19.5 million and $41.4 million for the same periods in 2024. The increase primarily reflects higher clinical trial and manufacturing expenses for MZE829 and MZE782 and personnel-related expenses, including non-cash stock-based compensation expense.

General & Administrative (G&A) Expenses: G&A expenses for the three and six months ended June 30, 2025, were $8.4 million and $16.2 million, respectively, and $5.9 million and $12.0 million for the same periods in 2024. The increase primarily reflects higher personnel-related expenses, including non-cash stock-based compensation expense, and fees for professional services.

Net (Loss) Income: Net loss for the three and six months ended June 30, 2025, was $33.7 million and $66.5 million, respectively, compared to net income of $139.1 million and $106.6 million for the same periods in 2024. Net income for the three and six months ended June 30, 2024 includes $165.0 million in license revenue recognized in connection with the license agreements with Shionogi and Trace.
