Alto Neuroscience raises $50 million to advance depression treatment

MOUNTAIN VIEW, Calif. - Alto Neuroscience, Inc. (NYSE:ANRO), currently valued at $164.63 million, announced Monday it has secured approximately $50 million in a private placement financing led by Perceptive Advisors, with participation from new and existing investors including Commodore Capital, Vestal Point Capital, Vivo Capital, and other biotech-focused investors. According to InvestingPro data, the company maintains a strong liquidity position with more cash than debt on its balance sheet, though it’s currently experiencing rapid cash burn.

The clinical-stage biopharmaceutical company plans to use the proceeds to accelerate development of ALTO-207, a fixed-dose combination of pramipexole and ondansetron, for treatment resistant depression (TRD). Following what the company described as a successful FDA meeting, Alto expects to initiate a Phase 2b study of ALTO-207 by mid-2026, which could potentially serve as a pivotal study. The company also plans to begin a Phase 3 study in TRD patients by early 2027. With a current ratio of 18.43, InvestingPro analysis shows the company’s liquid assets significantly exceed its short-term obligations, providing financial flexibility for these development plans.

In the financing, Alto is selling approximately 3.8 million shares of common stock at $5.914 per share and pre-funded warrants to purchase up to about 4.6 million shares to certain investors. The transaction is expected to close on October 21, 2025, subject to customary closing conditions.

ALTO-207 combines pramipexole, a dopamine D3-preferring D3/D2 agonist with demonstrated antidepressant effects, and ondansetron, a selective 5-HT3 receptor antagonist. According to the company, this combination is designed to enable higher dosing of pramipexole by mitigating dose-limiting adverse events.

In a previous Phase 2a clinical trial with 32 depression patients, the company reported that ALTO-207 met primary and secondary endpoints, demonstrating improvements on the Montgomery–Åsberg Depression Rating Scale compared to placebo. The market has responded positively to these developments, with ANRO’s stock showing a remarkable 169% return over the past six months. Analyst targets for the stock range from $4 to $15, reflecting diverse views on the company’s potential. Get more detailed insights and access to additional ProTips with InvestingPro.
