SAN FRANCISCO and BOSTON, Aug. 13, 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 second quarter ended June 30, 2026, and provided a business update.

“With positive Phase 2 data from ZEPHYR and continued progress in VISTA, we are focusing our efforts on advancing ML-007C-MA in both schizophrenia and ADP,” said Chris Kroeger, Co-Founder and Chief Executive Officer of MapLight. “In schizophrenia, ZEPHYR met its primary endpoint and achieved meaningful efficacy results, an encouraging cognitive signal and a tolerability profile designed to translate into real-world use, supporting our planned registrational Phase 3 ZEPHYR-2 trial. In ADP, enrollment in VISTA remains ongoing, with topline results expected in the second half of 2027. Together with our recent private placement and continued focus on capital discipline, we believe we are well positioned to execute on both programs through these key milestones.”

Business Update and Upcoming Milestones

ML-007C-MA (M₁/M₄ Muscarinic Agonist) for the Treatment of Schizophrenia

• Reported positive topline results in July 2026 from the Phase 2 ZEPHYR trial of ML-007C-MA in adults with schizophrenia experiencing an acute exacerbation of psychosis. The trial met its primary endpoint, with the 210/3 mg twice-daily dose demonstrating a statistically significant and clinically meaningful reduction in PANSS total score compared with placebo at Week 5.
• ML-007C-MA also demonstrated improvement on a prespecified cognitive-function endpoint in participants with baseline cognitive impairment and significant separation on key secondary endpoints, including CGI-S and the PANSS Marder positive factor.
• ML-007C-MA was generally well tolerated, with no serious or drug-related severe adverse events and low rates of GI-related discontinuations. Its clinical profile, including simple initiation, 99% of patients reaching the target dose and no fasting requirement, is designed to translate into real-world use.
• The Company plans to engage with the FDA at an End-of-Phase 2 meeting to discuss the registrational path forward, including the planned Phase 3 ZEPHYR-2 trial, with topline results expected in 2028.
  
  

ML-007C-MA for the Treatment of Alzheimer’s Disease Psychosis (ADP)

• Continued enrollment in the Phase 2 VISTA trial, a randomized, double-blind, placebo-controlled study evaluating ML-007C-MA in approximately 300 participants with ADP.
• ML-007C-MA received Fast Track designation from the FDA in December 2025 for the treatment of hallucinations and delusions associated with ADP.
• Topline results from VISTA are expected in the second half of 2027.
  
  

ML-004 (5-HT_1B/1D Agonist) for the Treatment of Autism Spectrum Disorder (ASD)

• Reported topline results in June 2026 from the Phase 2 IRIS trial of ML-004 in autism spectrum disorder. While the study did not meet its primary endpoint in social communication, a prespecified analysis demonstrated clinically meaningful improvements in irritability among adolescents with moderate or greater baseline irritability.
• ML-004 was generally well tolerated in the IRIS trial, with no severe or serious adverse events in the active treatment arm. This profile is relevant in a treatment setting with limited approved options, where antipsychotic-associated tolerability concerns can present challenges for long-term use, particularly in younger patients.
• Following its planned End-of-Phase 2 discussion with the FDA, the Company intends to evaluate the path forward for ML-004, including potential strategic collaborations and/or funding alternatives.
  
  

Corporate Updates

• In August 2026, the Company announced a $150 million private placement, with participation from new and existing institutional investors. Proceeds from the financing are expected to primarily support the continued advancement of ML-007C-MA, including funding the planned Phase 3 ZEPHYR-2 trial and ongoing Phase 2 VISTA trial, and for working capital and other general corporate purposes. Based on its current operational plans and assumptions, MapLight expects that its existing cash, cash equivalents and investments, together with the net proceeds from the PIPE, will be sufficient to fund the continued advancement of ML-007C-MA through 2028.
• The Company is focusing resources on the advancement of ML-007C-MA, including pausing further investment in preclinical and discovery-stage programs and foregoing advancement of those programs into clinical development under the current operating plan.
  
  

Second Quarter 2026 Financial Results

• Cash Position: Cash, cash equivalents and investments were $351.3 million as of June 30, 2026. Based on current operational plans and assumptions, the Company expects that its existing cash, cash equivalents and investments, together with the net proceeds from the recent private placement, will be sufficient to fund the continued advancement of ML-007C-MA through the end of 2028.
• R&D Expenses: Research and development (R&D) expenses were $53.4 million for the second quarter of 2026, as compared to $26.8 million for the second quarter of 2025. R&D expenses increased primarily due to increases in clinical trial expenses and employee-related expenses, including an increase in stock-based compensation expense of $5.6 million.
• G&A Expenses: General and administrative (G&A) expenses were $10.1 million for the second quarter of 2026, as compared to $3.8 million for the second quarter of 2025. G&A expenses increased primarily due to increases in employee-related expenses, including an increase in stock-based compensation expense of $2.9 million, and increases in professional fees and other expenses.
• Net Loss: Net loss was $60.2 million for the second quarter of 2026, as compared to $29.8 million for the second quarter of 2025.
