MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Alto Neuroscience, Inc. (“Alto”) (NYSE: ANRO) today reported financial results for the second quarter ended June 30, 2024, and highlighted recent corporate progress.
“Over the recent months we achieved several important milestones for our company and for the field of precision psychiatry as a whole,” said Amit Etkin, M.D., Ph.D., founder and chief executive officer of Alto Neuroscience. “Completing the enrollment of 301 patients in our Phase 2b study of ALTO-100 represents the first randomized double-blind study to be completed using our neurocognitive battery as a patient selection tool. We are looking forward to completing this study and reporting topline data in October 2024. Additionally, the funding award we received from Wellcome Trust supports our acceleration of the development of ALTO-100 in bipolar depression directly into a Phase 2b study. Bipolar depression has a similar neurobiological profile as that of the patients being evaluated in the MDD study, and the only approved treatments for this condition are antipsychotic medications. Taken together, these two studies of ALTO-100 across diagnoses have the potential to change the historical framework of neuropsychiatric treatment.”
Dr. Etkin added, “Further, we made notable advancements across our other pipeline programs. We now have five Phase 2 studies ongoing across four novel product candidates, all of which we expect to report topline data from before the end of 2026. Due to our capital efficient approach to running clinical trials, we expect our existing cash to provide operational runway into 2027, and through all five of our anticipated clinical readouts.”
Second Quarter 2024 and Recent Business Highlights
ALTO-100: Completed Enrollment in Ongoing Phase 2b Study in MDD, Initiated Phase 2b Study in Bipolar Depression
ALTO-100, a first-in-class, oral small molecule believed to work through enhancing neural plasticity, is in development for the treatment of major depressive disorder (MDD) and bipolar depression (BPD).
Alto is currently evaluating ALTO-100 in a 301-patient Phase 2b study in MDD patients characterized by a memory-based 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).
In June 2024, the Company completed a successful Type C meeting with the U.S. Food and Drug Administration (FDA), in which it sought feedback regarding the development of ALTO-100 using a memory-based marker for patient enrichment. In the meeting the U.S. FDA provided feedback regarding the ongoing Phase 2b study suggesting the results from the study would provide further clarity on the registrational path for ALTO-100. The Company provided an overview of the biological link between the patient phenotype, the memory biomarker, and the purported mechanism of ALTO-100.
The Company expects to report topline data from the Phase 2b MDD study in October 2024.
In July 2024, the Company announced the initiation of a Phase 2b study of ALTO-100 in patients with BPD. Bipolar depression has been shown to be associated with reduced neuroplasticity in the hippocampus, while ALTO-100 has been shown to directly increase hippocampal neuroplasticity. The 200-patient Phase 2b study is enrolling BPD patients characterized by the same memory-based cognitive biomarker as the MDD study. 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 clinical endpoint typically used as the regulatory endpoint in depression, the Montgomery-Åsberg Depression Rating Scale (MADRS). Bipolar depression has been identified as an important focus area for Wellcome Trust, and Alto received an $11.7 million funding award from Wellcome in support of this study.
The Company expects to report topline data from the Phase 2b BPD study in 2026.
ALTO-300: Enrollment on Track in 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 an antidepressant to which they had an insufficient response.
Alto is currently evaluating ALTO-300 in a 200-patient Phase 2b study in MDD patients characterized by an EEG biomarker signature. The study is evaluating ALTO-300 compared to placebo over a 6-week treatment period, and the primary outcome is 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: Initiated a Phase 2 Proof-of-Concept Study for Cognitive Impairment Associated with Schizophrenia (CIAS)
ALTO-101 is a novel brain-penetrant PDE4 inhibitor currently in Phase 2 clinical development for the treatment of CIAS.
PDE4 inhibitors have demonstrated, as a class, a propensity to induce significant dose-related 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 enhance the pharmacokinetic (PK) profile and improve the overall tolerability profile relative to other PDE4 inhibitors. Alto hypothesized that reducing the rate of drug absorption and delivering a stable blood target concentration could blunt typical PDE4-related adverse events such as nausea, vomiting, and diarrhea.
In April 2024, the Company reported positive results from a Phase 1 study evaluating the pharmacokinetic and tolerability profile of transdermal administration of ALTO-101 compared to oral administration. Overall, ALTO-101 demonstrated a favorable pharmacokinetic and tolerability profile. The novel transdermal formulation delivered significantly greater drug exposure with substantially fewer adverse events typically associated with PDE4 inhibitors. The drug exposure demonstrated by the transdermal formulation is expected to be sufficient to achieve the desired 30-40% target occupancy, which has been shown through positron emission tomography (PET) to be the relevant occupancy to induce the brain effects observed with oral administration of ALTO-101.
In June 2024, the Company initiated a Phase 2 proof-of-concept study in patients with CIAS. The study consists of a cross-over double-blind, placebo-controlled, dose-escalating treatment with ALTO-101 and placebo in patients with CIAS. Alto expects to enroll approximately 70 adult participants between 21-55 years old with schizophrenia and a demonstrable level of cognitive impairment. Alto will evaluate the effects of ALTO-101 on EEG markers relevant to cognitive function and will also explore its effects on cognitive performance. The primary outcome in the study is the effect of ALTO-101 on theta band activity, a measure best linked to CIAS in recent prospectively replicated Alto data analysis using two large schizophrenia datasets, as measured using EEG at the end of each dose period.
Enrollment is ongoing and the Company expects to report topline data in the second half of 2025.
ALTO-203: Initiated a Phase 2 Proof-of-Concept Study in 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 dopamine release in the reward system and on positive subjective emotional measures in humans.
In April 2024, Alto announced the initiation of a Phase 2 proof-of-concept study to evaluate ALTO-203 in patients with MDD and higher levels of anhedonia. The study consists of two sequential double-blind, placebo-controlled treatment periods with two dose levels of ALTO-203 being studied as monotherapy. The first period uses a randomized single-dose treatment design to evaluate patient pharmacodynamic responses to ALTO-203 compared to placebo. The powered primary outcome is measured by an acute change in positive emotion assessed by the alertness and mood components of the Bond-Lader Visual Analog Scale (BL-VAS), an established scale of subjective emotion also used in a prior Phase 1 study of ALTO-203. The second period uses a 28-day, multi-dose exposure design to assess the safety of ALTO-203 in patients with MDD. Exploratory, non-powered objectives for the multi-dose period will evaluate changes in measures of depression, anhedonia, and other clinical symptoms, along with cognition, EEG, and wearables.
Enrollment in this study is ongoing. Alto expects to enroll approximately 60 adult participants with MDD and evidence of anhedonia, and report topline data from this study in the first half of 2025.
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.
