Alto Neuroscience (NYSE: ANRO) announced plans to accelerate development of ALTO-207 for treatment resistant depression after a successful FDA meeting and a $50 million private placement to support expanded development. The company expects to initiate a Phase 2b potentially pivotal trial by mid-2026 and to begin a Phase 3 study by early 2027 pending Phase 3 readiness and protocol alignment with the FDA. Alto reported blinded PK results showing 96% PK-positive samples for ALTO-100 and 100% for ALTO-101, and it now guides cash runway into 2028 while adding ALTO-207 activities. Topline data for ALTO-101 remain expected in 1Q 2026.
Alto Neuroscience (NYSE: ANRO) announced on October 3, 2025 that the U.S. FDA granted Fast Track designation to ALTO-101 for the treatment of cognitive impairment associated with schizophrenia (CIAS). ALTO-101 is a novel PDE4 inhibitor that increased cAMP and showed pro‑cognitive effects in healthy volunteers in Phase 1, with significant effects on EEG measures and cognitive performance. Enrollment is ongoing in a Phase 2 proof-of-concept study in patients with CIAS. Fast Track status may enable more frequent FDA interactions and potential eligibility for accelerated approval or priority review if criteria are met.
Alto Neuroscience (NYSE:ANRO) announced positive results from an independent replication study validating EEG biomarkers in schizophrenia patients. The study confirmed that theta-band inter-trial coherence (ITC) effectively distinguishes individuals with schizophrenia from healthy controls.
The analysis, involving 155 schizophrenia patients and 272 healthy controls, demonstrated that theta ITC and event-related spectral perturbation (ERSP) showed the strongest case-control differences (Cohen's d = 0.64 and 0.78, respectively; p 0.001). Both measures significantly correlated with processing speed, a key cognitive impairment indicator in schizophrenia.These findings support Alto's use of theta ITC as a primary outcome measure in their ongoing Phase 2 trial of ALTO-101, a PDE4 inhibitor being developed for cognitive impairment associated with schizophrenia (CIAS).
Alto Neuroscience (NYSE:ANRO), a clinical-stage biopharmaceutical company developing precision medicines for neuropsychiatric disorders, has announced its participation in four upcoming investor conferences in August and September 2025.

Alto Neuroscience (NYSE: ANRO) announced the publication of the PAX-D study results in The Lancet Psychiatry, evaluating pramipexole for treatment-resistant depression (TRD). The study, conducted by the University of Oxford and funded by the UK's National Institute for Health and Care Research, demonstrated significant clinical benefits.
The study showed that pramipexole augmentation of antidepressant treatment at a 2.5mg target dose achieved a large reduction in symptoms (Cohen's d=0.87) compared to placebo at 12 weeks, although it was associated with high adverse effects. These findings informed Alto's acquisition of ALTO-207, a fixed-dose combination of pramipexole and ondansetron, designed to maintain efficacy while reducing side effects.
Alto plans to initiate a potentially pivotal Phase 2b trial of ALTO-207 by mid-2026, collaborating with the National Health Service and PAX-D clinical sites. The company aims to leverage its proprietary dopamine biomarker insights in depression to optimize the treatment approach.
Alto Neuroscience (NYSE:ANRO) has announced positive pharmacodynamic results from its exploratory Phase 2 proof-of-concept trial of ALTO-203, a novel oral histamine H3 inverse agonist for major depressive disorder (MDD) patients. The trial successfully identified a biomarker (EEG theta/beta ratio) for patient selection and demonstrated the drug's pro-cognitive and wake-promoting effects.
Key findings include significant improvements in sustained attention (p0.05 at 25µg dose), confirmed by wearable devices (p0.05 at 25µg; p<0.001 at 75µg), and improvements in the MADRS score (2 points at week 3 for 25µg dose). The study enrolled and showed ALTO-203 was well-tolerated, with insomnia being the most common side effect.
