MZE829 Phase 2 HORIZON Trial Enrolling Patients with APOL1 Kidney Disease (AKD); Initial Data Expected in Q1 2026 MZE782 Phase 1 Healthy Volunteer Trial Ongoing; Initial Data Expected in H2 2025 Raised $140 Million in Gross Proceeds in Upsized IPO in February 2025, Providing Expected Cash Runway into H2 2027 SOUTH SAN FRANCISCO, Calif., March 31, 2025 (GLOBE NEWSWIRE) -- Maze Therapeutics, Inc. (Nasdaq: MAZE), a clinical-stage biopharmaceutical company developing small molecule precision medicines for patients with renal, cardiovascular and metabolic diseases, today reported financial results for the fourth quarter and year ended December 31, 2024, highlighted recent progress and reiterated upcoming milestones. “Maze has reached a pivotal moment in our journey. On the heels of a successful IPO and with two ongoing clinical-stage programs - MZE829 for AKD and MZE782 for both chronic kidney disease (CKD) and phenylketonuria (PKU) - we are making meaningful progress towards advancing genetic-based medicines with the potential to transform patient care,” said Jason Coloma, Ph.D., chief executive officer of Maze. “We look forward to reporting initial Phase 1 data for MZE782 in healthy volunteers in the second half of 2025, which will enable us to prepare to initiate Phase 2 trials in CKD and PKU. We also expect to report initial data from the Phase 2 HORIZON trial of MZE829 in patients with AKD in the first quarter of next year. With a strong financial foundation, highly accomplished team and clear mission, we are well-positioned to execute our milestones and deliver breakthrough medicines to patients.” Pipeline Accomplishments and Upcoming Milestones MZE829 for AKD MZE829 is an oral, small molecule APOL1 inhibitor that Maze is advancing as a potential treatment for patients with AKD, a subset of CKD estimated to affect over one million people in the United States alone. In February 2025, Maze dosed the first patient in the Phase 2 HORIZON Study of MZE829 in patients with AKD. The trial is enrolling a broad population of AKD patients, including those with more severe disease who have nephrotic range proteinuria, focal segmental glomerulosclerosis (FSGS), patients with lower levels of proteinuria and hypertensive nephropathy and patients with proteinuria and diabetic kidney disease. Maze expects to announce topline data from the Phase 2 trial in the first quarter of 2026. In October 2024, Maze reported positive Phase 1 results for MZE829 in healthy volunteers, which demonstrated that MZE829 was well tolerated at single doses up to 480 mg and multiple doses up to 350 mg daily over seven days, with dose-proportional pharmacokinetics and low variability. The observed half-life of approximately 15 hours supports once-daily dosing of MZE829. MZE782 in CKD and PKU MZE782 is an oral small molecule targeting the solute transporter SLC6A19, with potential to be a first-in-class treatment for approximately five million U.S. patients with CKD who have inadequate responses to currently available CKD therapies, as well as those with PKU, an inherited metabolic disorder. In September 2024, Maze initiated a Phase 1 clinical trial of MZE782 in healthy volunteers. Maze expects to report initial data, including proof-of-mechanism biomarkers, in the second half of 2025. Based on Phase 1 results, Maze plans to initiate two parallel Phase 2 clinical trials of MZE782 in CKD and PKU. Corporate Highlights In February 2025, Maze completed an upsized IPO, raising approximately $140 million in gross proceeds, before deducting underwriting discounts and commissions and other offering expenses, through the sale of 8,750,000 shares at $16.00 per share. In November 2024, Maze closed an oversubscribed $115 million Series D financing co-led by Frazier Life Sciences and Deep Track Capital, with participation from Janus Henderson Investors and Logos Capital. Approximately $40 million of the $115 million represented the conversion of previously issued convertible notes held by existing investors. Combined gross proceeds of approximately $255 million from the two financings are expected to provide runway into the second half of 2027, supporting completion of Phase 2 clinical trials for MZE829 in AKD and MZE782 in CKD and PKU, as well as continued advancement of additional preclinical programs. Fourth Quarter and Full Year 2024 Financial Results Cash Position: Cash and cash equivalents were $196.8 million as of December 31, 2024, compared to $29.2 million as of December 31, 2023. Maze expects its current cash and cash equivalents, which includes proceeds from its February 2025 IPO, will fund operations into the second half of 2027. License Revenue: License revenue was $167.5 million for the year ended December 31, 2024, compared to none for the year ended December 31, 2023. The increase was primarily due to the receipt of a one-time upfront payment of $150.0 million in May 2024 under the license agreement with Shionogi & Co., Ltd. (Shionogi) for the development of MZE001 in Pompe disease. No license revenue was recognized for the fourth quarter of 2024 and 2023. Research & Development (R&D) Expenses: R&D expenses were $22.2 million for the fourth quarter of 2024 and $83.5 million for the year ended December 31, 2024, compared to $16.0 million for the fourth quarter of 2023 and $73.9 million for the year ended December 31, 2023. This year-over-year increase primarily reflects higher clinical trial expenses for MZE829 and MZE782 as well as for preclinical studies for MZE782. General & Administrative (G&A) Expenses: G&A expenses were $7.5 million for the fourth quarter of 2024 and $26.4 million for the year ended December 31, 2024, compared to $7.0 million for the fourth quarter of 2023 and $24.6 million for the year ended December 31, 2023. This year-over-year increase primarily reflects higher personnel-related expenses, including non-cash stock-based compensation expense, partially offset by lower expenses for professional services. Net (Loss) Income: Net loss was $29.6 million for the fourth quarter of 2024 and net income was $52.2 million for the year ended December 31, 2024, compared to net loss of $26.6 million for the fourth quarter of 2023 and net loss of $100.4 million for the year ended December 31, 2023. Net income for the year ended December 31, 2024 includes $167.5 million in license revenue recognized under various license agreements, including the exclusive license agreement with Shionogi.
