Leal Therapeutics Announces $30 Million Series A to Progress First-In-Class Neuro-Metabolic Therapies for Neurodegenerative and Neuropsychiatric Disorders with High-Unmet Need

Leal Therapeutics is developing first-in-class therapeutics to correct metabolic imbalances in the brain for treatment of high unmet need CNS disorders

Financing advances LTX-001 through clinical efficacy data in schizophrenia patients, LTX-002 through initial clinical data in ALS, and progresses additional pipeline programs

WORCESTER, Mass., Aug. 27, 2025 /PRNewswire/ -- Leal Therapeutics, Inc., a biotechnology company developing novel therapeutics for patients with disorders of the central nervous system (CNS), today announced a $30 million Series A financing. The round was led by SV Health Investors' Dementia Discovery Fund (DDF), in addition to existing investors OrbiMed, Newpath Partners, Chugai Venture Fund, Euclidean Capital, Alexandria Venture Investments, and PhiFund.

Leal's approach is rooted in the core principle that correcting metabolic imbalances in the brain is key to the development of effective therapies for patients living with neuropsychiatric or neurodegenerative disorders. This approach is supported by extensive human genetics, human biomarker, and preclinical model data. Leal's lead program, LTX-001, is a clinical-stage, first-in-class brain-penetrant oral small molecule targeting excessive glutamate by inhibiting the mitochondrial enzyme glutaminase, for patients with psychiatric disorders including schizophrenia, Bipolar Disorder, Major Depressive Disorder as well as amyotrophic lateral sclerosis (ALS). Data from an initial clinical study of LTX-001 support safety and effective target engagement. Leal is also developing LTX-002, a near-clinical stage antisense oligonucleotide (ASO) for patients with genetic or sporadic ALS. LTX-002 targets the de novo synthesis of ceramides/sphingolipids by inhibiting the first and rate-limiting enzyme in this pathway, SPT, and more specifically the SPTLC1 subunit. Excessive ceramides/sphingolipids are implicated in ALS and other neurodegenerative disorders. Leal is also developing LTX-007, a small molecule inhibitor of SPT, for neurodegenerative disorders such as Alzheimer's disease, ALS and inherited sphingolipidoses.  In addition to the programs above, Leal is advancing next-generation technology to optimize delivery of nucleic acid therapeutics to the CNS through the blood brain barrier (BBB) using antibody-like shuttles. 

Proceeds from the Series A financing will be used to advance LTX-001 through a clinical trial in schizophrenia patients, as well as progress LTX-002 through initial clinical data in ALS. "This financing enables us to further progress our first-in-class neuro-metabolic pipeline to clinical data for patients with severe unmet needs," said Asa Abeliovich, M.D., Ph.D., founder and chief executive officer of Leal. "We're grateful to our new and existing investors for their shared commitment to advancing this work."

In connection with the financing, Christian Jung, Ph.D., Partner at SV Health Investors, joined Leal's board of directors. "Leal is advancing promising and highly differentiated programs for CNS disorders with a clear clinical strategy and a uniquely qualified team," said Dr. Jung. "We believe the company is well-positioned to make significant strides in the treatment of neurodegenerative and neuropsychiatric diseases. We're proud to support Leal as they take this next critical step."
