Alto Neuroscience, Inc. (“Alto”) (NYSE: ANRO), a clinical-stage biopharmaceutical company focused on the development of novel precision medicines for neuropsychiatric disorders, today announced that the Company has been awarded $11.7 million by the Wellcome Trust to advance the clinical development of lead candidate ALTO-100 through a Phase 2b study in patients with bipolar depression characterized by a cognitive biomarker. The Company has initiated this study and expects to report topline data in 2026.
“Bipolar depression is among the most challenging psychiatric conditions, yet the only available treatments are antipsychotics, which carry limited efficacy and substantial side effects,” said Amit Etkin, M.D., Ph.D., founder and chief executive officer of Alto Neuroscience. “Bipolar depression is associated with memory, cognitive, and neuroplasticity abnormalities at similar or greater rates than seen in major depression. Given the pro-neuroplasticity mechanism of ALTO-100, we have an opportunity to address an important subset of patients displaying a similar neurobiological profile. We are grateful to Wellcome for their commitment to addressing this devastating condition and eagerness to accelerate our late-stage clinical program as we work to develop the first precision treatment for bipolar disorder.”
Dr. Lynsey Bilsland, Head of Mental Health Translation at Wellcome, added, “We are committed to funding research and innovation to advance early intervention in mental health, helping create a world where people do not feel held back from the lives they wish to lead. We’re encouraged by Alto’s precision psychiatry drug candidate, which has the potential to have a significant impact on patients affected by bipolar depression and other mental health conditions. To make meaningful and effective progress, we must support these opportunities that promote targeted treatment approaches for patients, particularly in an industry that has relied on trial-and-error for too long.”
ALTO-100, a first-in-class, oral small molecule believed to work through enhancing neural plasticity, is currently in Phase 2b development for the treatment of major depressive disorder (MDD), with topline results expected in October 2024. Previously, Alto reported positive results from a Phase 2a study of ALTO-100 in MDD and post-traumatic stress disorder (PTSD), in which favorable safety and tolerability were established, and patients with a memory-based cognitive biomarker signature exhibited greater response to the drug candidate.
The Company is leveraging the same memory biomarker and study design being employed in the ongoing Phase 2b study of ALTO-100 in MDD. The randomized, double-blind, placebo-controlled study is expected to enroll approximately 200 adults with bipolar depression. Patients will be evaluated over a six-week treatment period. The primary endpoint is the change from baseline on the Montgomery-Åsberg Depression Rating Scale (MADRS), consistent with the endpoint in the ongoing Phase 2b MDD study, and the commonly used endpoint in registrational studies in bipolar depression.

About ALTO-100
ALTO-100 is a novel oral small molecule that has shown evidence of a pro-neurogenesis/neuroplasticity mechanism of action and first-in-class therapeutic potential. ALTO-100 is being developed for major depressive disorder (MDD) and bipolar depression, disease states characterized by cognitive impairment with no currently available treatments targeting these symptoms. In Phase 2a clinical trials, ALTO-100 demonstrated favorable safety and tolerability, and significantly greater treatment response in patients with an objectively defined cognitive biomarker.
About the ALTO-100 Cognitive Biomarker
Alto leverages its Precision Psychiatry Platform™ to identify brain-based biomarkers as predictors of response to medication. The predictive biomarker identified, and prospectively replicated, for ALTO-100 is a test of verbal memory, or the ability to recall lists of unrelated words. Verbal memory is a direct measure of hippocampal neuroplasticity; therefore, selecting patients based on poor performance on this test provides a clear biological link between the proposed pro-plasticity mechanism of ALTO-100 and this characteristic of responsive patients. The test used to compute the biomarker score is Alto’s digital adaptation of a well validated instrument that has been used in clinical practice for assessing memory for more than 80 years and is highly test-retest reliable. The web-based memory test is self-administered and can be completed by the patient in less than 20 minutes in any setting, including at home. This convenient, reliable, and efficient test enables high-quality data collection at a broad clinical scale.
