**SAN FRANCISCO and BOSTON, March 26, 2026 (GLOBE NEWSWIRE)** -- MapLight Therapeutics, Inc. (Nasdaq: MPLT), a clinical-stage biopharmaceutical company focused on improving the lives of patients suffering from debilitating central nervous system disorders, today reported financial results for the fourth quarter and full year ended December 31, 2025, and provided a business update.

"With a focused strategy, robust operational execution and a strong balance sheet, MapLight is well positioned to deliver on multiple key development milestones in 2026," said Chris Kroeger, co-Founder and Chief Executive Officer of the Company. "While continuing to prioritize high-quality trial execution, we have maintained a robust enrollment pace in the ZEPHYR study and expect to reach target enrollment in April 2026. This is shaping up to be an exciting year for MapLight as we look forward to reporting topline results from our Phase 2 ZEPHYR trial and ML-004 Phase 2 IRIS trial in the third quarter. In addition, we expanded our earlier-stage pipeline with the addition of ML-055, our next-generation M1/M4 agonist program that we are rapidly advancing towards potential candidate nomination this year."

**<u>Business Update and Upcoming Milestones</u>**

• **ML-007C-MA (M1/M4 Muscarinic Agonist) for the Treatment of Schizophrenia and Alzheimer's Disease Psychosis (ADP):**

o**Phase 2 ZEPHYR trial for schizophrenia is expected to reach target enrollment in April 2026, with topline results expected in the third quarter of 2026.** ZEPHYR is a randomized, double-blind, placebo-controlled trial evaluating the efficacy, safety, and tolerability of ML-007C-MA in inpatient adult participants with schizophrenia experiencing an acute exacerbation of psychosis. The study is expected to enroll approximately 300 participants, randomized 1:1:1 to receive either placebo, ML-007C-MA 210/3 mg twice daily, or ML-007C-MA 330/6 mg once daily.

------

The primary endpoint for the trial is the change in Positive and Negative Syndrome Scale (PANSS) total score from baseline to Week 5. Key secondary endpoints include change in PANSS-Marder positive and negative factor scores and CGI-S score from baseline to Week 5.<br>

o**Topline results from Phase 2 VISTA trial for ADP expected in the second half of 2027.** VISTA is a randomized, double-blind, placebo-controlled trial evaluating ML-007C-MA for the treatment of ADP. The Company expects to enroll approximately 300 participants in the trial. In December 2025, ML-007C-MA was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of hallucinations and delusions associated with ADP.<br>

• **ML-004 (5-HT1B/1D Agonist) for the Treatment of Autism Spectrum Disorder (ASD):** The Company has completed enrollment in the IRIS Phase 2 trial, with topline results expected in the third quarter of 2026. The IRIS study is a randomized, double-blind, placebo-controlled trial evaluating ML-004 for the improvement of core social communication deficits, with change in irritability symptoms as a key secondary endpoint. The trial randomized approximately 160 adult and adolescent participants. <br>

• **ML-055 (Next-Generation M1/M4 Muscarinic Agonist) for the Treatment of Neuropsychiatric Conditions:** Preclinical in vitro and in vivo studies evaluating multiple potential candidates in the Company's ML-055 M1/M4 muscarinic agonist program have demonstrated significantly greater potency relative to ML-007 and the potential for once-daily dosing and a long-acting injectable formulation. The Company expects to nominate a preclinical candidate to advance to IND-enabling studies in 2026.

**<u>Fourth Quarter and Full Year 2025 Financial Results</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Cash Position:** Cash, cash equivalents and investments were $453.1 million as of December 31, 2025. Based on current operational plans and assumptions, the Company expects that its current cash, cash equivalents and investments will be sufficient to fund operations through 2027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**R&D Expenses:** Research and development (R&D) expenses were $64.6 million for the fourth quarter of 2025, as compared to $20.7 million for the prior year period. For the full year 2025, R&D expenses were $138.3 million, as compared to $68.5 million for the full year 2024. R&D expenses increased primarily due to clinical trial and CMC expenses and employee-related expenses, including stock-based compensation related to the vesting of restricted stock units in connection with the effectiveness of the IPO, which were partially offset by decreases in preclinical program expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**G&A Expenses:** General and administrative (G&A) expenses were $18.8 million for the fourth quarter of 2025, as compared to $2.1 million for the prior year period. For the full year 2025, G&A expenses were $30.7 million, as compared to $14.4 million for the full year 2024. G&A expenses increased primarily due to employee-related expenses, including stock-based compensation related to the vesting of restricted stock units in connection with the effectiveness of the IPO, in addition to professional fees and other expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Net Loss:** Net loss was $79.5 million for the fourth quarter of 2025, as compared to $21.2 million for the prior year period. For the full year 2025, net loss was $161.2 million, as compared to $77.6 million for the full year 2024.
