LOS ALTOS, Calif.--(BUSINESS WIRE)--Alto Neuroscience, Inc. (“Alto”) (NYSE: ANRO) today reported financial results for the full year ended December 31, 2023, and highlighted recent corporate progress.
“2024 is shaping up to be a transformational year for Alto as we advance our mission of redefining the treatment paradigm for patients with neuropsychiatric disorders,” said Amit Etkin, M.D., Ph.D., founder and CEO of Alto Neuroscience. “Our lead product candidates, ALTO-100 and ALTO-300, have demonstrated positive Phase 2a results and we remain focused on clinical execution to deliver value to patients and our shareholders. Looking ahead, we are on track to report data from the Phase 2b depression studies of ALTO-100 and ALTO-300 in the second half of 2024 and the first half of 2025, respectively, in biomarker characterized patients.”
Nick Smith, CFO of Alto Neuroscience, added, “As we begin 2024, Alto is in its strongest financial position to date. With the proceeds from our IPO, combined with our existing cash balance, we are well-positioned to read out data from at least four important studies across our clinical-stage pipeline over the next two years.”
Full Year 2023 and Recent Business Highlights
ALTO-100: Ongoing Phase 2b Study in MDD
ALTO-100, a first-in-class, oral small molecule believed to work through enhancing neural plasticity, is in development in Phase 2b for the treatment of major depressive disorder (MDD). In January 2023, Alto reported positive results from a Phase 2a study in which patients with MDD and a cognitive biomarker signature were identified as more responsive to ALTO-100. This signal was prospectively replicated to predict clinical response in an independent, locked, and blinded data set of patients from the same study.
Alto is currently evaluating ALTO-100 in a 266-patient Phase 2b study in MDD patients characterized by the cognitive biomarker. The study is evaluating ALTO-100 compared to placebo over a 6-week double blind treatment period. The primary endpoint is the change from baseline on the standard regulatory clinical endpoint in depression, the Montgomery-Åsberg Depression Rating Scale (MADRS).
Enrollment is ongoing and the Company expects to report topline data in the second half of 2024.
ALTO-300: Ongoing Phase 2b Study in MDD
ALTO-300 (agomelatine), an oral small molecule that is believed to act as a melatonin agonist and 5HT2C antagonist, is being developed as a new treatment for patients with MDD as an adjunctive treatment to a standard antidepressant.
ALTO-300 has demonstrated positive results in Phase 2a in patients with MDD in which patients with an EEG biomarker signature were discovered to have more robust response to ALTO-300 compared to those without the biomarker signature. The biomarker signature was prospectively replicated to predict clinical response in an independent, locked, and blinded data set. The Company initiated a Phase 2b study in 200 patients with MDD. In the Phase 2b study ALTO-300 will be evaluated compared to placebo over a 6-week treatment period, and the primary outcome will be the change from baseline in MADRS score.
Enrollment is ongoing and the Company expects to report topline data in the first half of 2025.
ALTO-101: PDE4 Inhibitor in Development for Cognitive Impairment in Schizophrenia (CIAS)
ALTO-101 is a novel PDE4 inhibitor currently in Phase 1 clinical development for the treatment of CIAS. In December 2023, the Company reported positive results from a Phase 1 study in which ALTO-101 was shown to positively impact key brain pharmacodynamic markers relevant to cognition that are indicative of potential clinical benefit.
PDE4 inhibitors have demonstrated, as a class, a propensity to induce significant adverse events, historically limiting their development in CNS disorders. Alto is developing ALTO-101 as a novel transdermal formulation in partnership with MedRx Co., Ltd. to potentially enhance the pharmacokinetic profile and improve the overall tolerability profile relative to other PDE4 inhibitors. The Company expects to report data from a Phase 1 study evaluating the PK properties of the transdermal formulation in the first half of 2024, and subsequently initiate a proof-of-concept study in patients with CIAS.
ALTO-203: Histamine H3 Inverse Agonist in Development for MDD with Anhedonia
ALTO-203 is a novel, oral small molecule that uniquely acts as a histamine H3 inverse agonist, a histamine receptor primarily expressed in the brain. The Company is developing ALTO-203 as a novel treatment for patients with MDD and increased levels of anhedonia given the demonstrated effects of ALTO-203 on subjective affective clinical measures.
ALTO-203 was previously studied in a Phase 1 study and demonstrated significant acute benefits on a scale of subjective positive emotion, compared to placebo. The magnitude of this effect was shown to be equivalent to, or better than modafinil, an active comparator with demonstrated antidepressant activity in clinical trials.
In January 2024, Alto received IND clearance for ALTO-203 and expects to initiate a proof-of-concept study in the first half of 2024 in patients with MDD and increased levels of anhedonia.
ALTO-202: NMDAr Antagonist in Development for Depression
ALTO-202 is a novel, oral small molecule believed to specifically target the GluN2b subunit of NMDA receptors, acting as a selective NMDA receptor antagonist. Alto plans to develop ALTO-202 for patients with depression.

R&D Expenses: Research and development expenses for the full year ended December 31, 2023 were $30.3 million, as compared to $23.7 million for the same period in 2022. The increase was primarily attributable to costs associated with the Phase 2a clinical studies for ALTO-100 and ALTO-300, which were completed in 2023.
G&A Expenses: General and administrative expenses for the full year ended December 31, 2023 were $7.5 million, as compared to $5.5 million for the same period in 2022.
