NEW YORK, May 12, 2026 (GLOBE NEWSWIRE) -- Ovid Therapeutics Inc. (Nasdaq: OVID), a biopharmaceutical company dedicated to pioneering better, gentler medicines for brain disorders with significant unmet need, today provided business updates including financial results for the first quarter ended March 31, 2026.

“Our first quarter reflected focused execution and continued progress across our pipeline of potentially transformative small molecule medicines for intractable brain conditions,” stated Meg Alexander, President and Chief Executive Officer. “Our development programs remain on track, our clinical organization has expanded, and we expect to be well capitalized into 2029, positioning us for multiple anticipated proof-of-concept and proof-of-signal readouts. We are especially pleased to have initiated Phase 1 dosing this month for our oral KCC2 direct activator, OV4071, alongside the expansion of OV329’s development programs, as we advance therapies targeting mechanisms central to excitatory/inhibitory balance in the brain.”

PIPELINE AND BUSINESS UPDATES

OV329: Higher dose cohorts demonstrate favorable safety, tolerability, PK and exposure profile, supporting advancement into patient studies

In March 2026, Ovid reported a favorable safety and tolerability profile from a 7 mg dose cohort of OV329, a next-generation GABA-AT inhibitor being developed for drug-resistant epilepsies. The Company also tested a higher dose cohort at 9 mg in April 2026 to further characterize the safety and tolerability profile above the intended clinical dose. Across all doses tested, including at the higher 9 mg dose, OV329 demonstrated a favorable safety and tolerability profile in clinical studies, with no treatment-related serious adverse events observed. These 7 mg dose results build upon previously reported positive biomarker results, which provided linear and predictable pharmacokinetics, and delivered the desired drug exposure in human plasma to maximize the Company’s pharmacology strategy for optimal enzyme inhibition. The targeted exposure levels have been associated with cortical inhibition in humans and anti-convulsant activity in pharmacodynamic models.

OV329 Phase 2 development: Advancing dose-confirmatory and proof-of-concept studies in treatment-resistant epilepsies

Ovid believes the drug exposure, PK, safety, and tolerability profile observed with the 3 mg, 5 mg, 7 mg and 9 mg doses of OV329 are supportive of continued clinical development and provide dose optionality for planned Phase 2 proof-of-concept and dose confirmatory studies.

Ovid plans to initiate an open-label photo paroxysmal response (PPR) study to evaluate the anti-seizure potential of OV329. PPR studies are a well-recognized methodology for characterizing anti-convulsant activity potential by evaluating the electroencephalography (EEG) PPR response as a predictor of anti-seizure effect in a photo-sensitive seizure population.

In parallel, the Company plans to launch a Phase 2 randomized, placebo-controlled trial designed to determine seizure reduction efficacy, safety and tolerability in people living with treatment-resistant focal onset seizures (FOS). Ovid anticipates initiating the Phase 2 study in the second quarter of 2026.

OV329: Adding complementary development programs in TSC and IS

Ovid announced plans to add two new development programs for OV329 to assess its efficacy in TSC-associated seizures and IS using a pediatric formulation. GABA-AT inhibition is a validated anti-convulsant mechanism of action in these conditions; however, it is underutilized commercially today due to compound-specific safety concerns associated with the first-generation GABA-AT inhibitor, vigabatrin. With OV329, the Company intends to develop a next-generation GABA-AT inhibitor that is safe, efficacious, and well tolerated and which thereby, might be used as an earlier line therapy and for increased duration of treatment relative to vigabatrin. There is tremendous unmet medical need in these severe pediatric epilepsies and there have been few-to-no new medicines approved in these conditions in the last twenty years.

Ovid plans to initiate a proof-of-concept safety and signal-finding study in Q4 2026 to evaluate OV329 in patients with TSC-associated seizures. Additionally, the Company plans to launch a safety and signal finding study to evaluate patients with IS in 2027.

KCC2 direct activator portfolio: Humans dosed with OV4071 in Q2 2026; advancing additional unique KCC2 development candidates from discovery engine

Ovid recently dosed the first participant in its Phase 1 study evaluating OV4071 in healthy volunteers. Additionally, in April 2026, the Company highlighted its KCC2 portfolio at a dedicated R&D event. The R&D event featured experimental, translational and clinical experts in schizophrenia and psychosis and reviewed extensive pharmacodynamic data, translational and clinical strategies. The Company is developing multiple, unique molecules with differentiated therapeutic profiles and formulations for potential conditions including a range of psychoses, neurodegenerative and neurodevelopmental disorders and epilepsies.

Key programs include:

• OV4071 (Oral KCC2 activator); Initiated a Phase 1 study and dosed healthy volunteers: OV4071, Ovid’s lead oral direct activator intended for chronic conditions, is advancing in an ongoing Phase 1 study in healthy volunteers. As part of the clinical development plan, Ovid intends to conduct a ketamine challenge study in the second half of 2026 to further characterize potential pharmacodynamic effects and proof-of-mechanism using electrophysiology and biomarkers. Ovid plans to study OV4071 initially in Parkinson’s disease psychosis and Lewy body dementia psychosis, as well as schizophrenia. At the American Psychiatric Association (APA) Annual Meeting, taking place May 16-20, 2026, in San Francisco, Ovid will present a poster showcasing preclinical work that supports KCC2 direct activation as a potential new approach for psychosis and reflects continued progress in the development of Ovid’s KCC2 direct activator portfolio.
• KCC2 portfolio expansion; Advancing next-generation compounds to support broad CNS therapeutic potential: Ovid has a discovery engine focused on identifying novel KCC2 direct activator molecules that are amenable for oral and injectable administration and moving them into IND-enabling studies. The Company believes KCC2 direct activation may have expansive therapeutic potential and is building a sustainable pipeline designed to unlock the full therapeutic potential of this novel mechanism across multiple indications.
  
  

BUSINESS STRATEGY AND UPDATES

Recent Events

On April 17, 2026, the Series A warrants issued by the Company in connection with its October 2025 private placement expired. The aggregate number of common shares underlying the Series A warrants was 38,481,325, and investors elected to exercise the warrants into 33,597,860 shares of the Company’s common stock for $1.40 per share and 4,883,464 pre-funded warrants for $1.399 per share, resulting in proceeds to the Company of approximately $53.9 million of which $26.6 million was received in March, and $27.3 million was received in April.

Separately, in March 2026, the Company raised $60.0 million in gross proceeds in a private placement financing, with participation from leading healthcare investors. The Company plans to use the net proceeds of $56.2 million to support expansion of OV329 into TSC and IS. The proceeds from the exercise of the Series A Warrants, together with the proceeds from the private placement financing, are expected to extend the Company’s financial runway into 2029.
