NEW YORK, March 18, 2026 (GLOBE NEWSWIRE) -- Ovid Therapeutics Inc. (Nasdaq: OVID), a biopharmaceutical company developing small molecule medicines for brain disorders with significant unmet need, today provided pipeline progress and business updates, including financial results for the fourth quarter and full year ended December 31, 2025. The Company reported favorable topline safety, tolerability and pharmacokinetics (PK) findings from the 7 mg dose cohort of OV329, its next generation GABA-aminotransferase (GABA-AT) inhibitor. Additionally the Company announced it will add complementary development programs for OV329, expanding into tuberous sclerosis complex (TSC) seizures and infantile spasms (IS) which is funded by a private placement financing expected to result in gross proceeds of
The Company will initiate a Phase 1 trial for OV4071, a potential first-in-class, oral, direct activator of potassium-chloride cotransporter 2 (KCC2) following Human Research Ethics Committee (HREC) approval of the Phase 1 study and Clinical Trial Notification (CTN) acknowledgement from the Australian Therapeutic Goods Administration (TGA).
“We are achieving important steps forward in our mission to pioneer better, gentler medicines for disorders of the brain. We believe today’s data continue to support OV329’s potential best-in-category profile and give us further conviction to expand OV329 into two complementary indications, tuberous sclerosis complex seizures and infantile spasms, for which GABA-AT inhibition is a validated mechanism of action. Additionally, we are rapidly advancing OV4071 into the clinic to explore its broad therapeutic potential,” said Meg Alexander, President and Chief Executive Officer. “Together, these developments reflect the strength of our scientific approach to restoring the balance of excitation and inhibition in the brain. Today’s plans will add to our growing cadence of near-term clinical milestones, and position Ovid to deliver meaningful progress for patients and value for stockholders over the months and years ahead.”
PIPELINE AND BUSINESS UPDATES
OV329: New 7 mg cohort demonstrates favorable safety and tolerability profile; advancing into patient studies
Today, Ovid announced new results from a 7 mg dose cohort evaluating the safety and tolerability of OV329, a next-generation GABA-AT inhibitor being developed for drug-resistant epilepsies. Following the cortical inhibition and tolerability demonstrated by OV329 at 3 mg and 5 mg doses, Ovid conducted further characterization of a 7 mg cohort to inform dose selection for planned patient studies.
The 7 mg Phase 1 study included both single ascending dose (SAD) and multiple ascending dose (MAD) cohorts, each consisting of six participants receiving OV329 and two participants receiving placebo. There were no treatment-related adverse events in the 7 mg cohort, and in a total of 19 unrelated adverse events, all were mild and transient. Across all doses tested, OV329 continues to demonstrate a favorable safety and tolerability profile in clinical studies, with no treatment-related serious adverse events observed. These findings continue to support a potential best-in-category profile.
The 7 mg dose data builds upon previously reported, positive biomarker results associated with the 3 mg and 5 mg doses of OV329, which were presented at the 2025 American Epilepsy Society (AES) annual meeting in December 2025. At those doses, OV329 demonstrated strong, statistically significant cortical inhibition activity and increase in GABA as measured across multiple metrics. The cortical inhibition results associated with OV329 matched or exceeded those demonstrated by therapeutic doses of vigabatrin as measured in previous studies using the same methodology. Findings confirm OV329 penetrates the brain, engages the target, and achieves biological modulation as expected of elevated levels of GABA, the major inhibitory neurotransmitter.
Extensive ophthalmic assessments, including best corrected visual acuity, fundus photography, indirect dilated ophthalmoscopy, optical coherence tomography and automated threshold visual field perimetry, showed no evidence of ophthalmic or retinal changes associated with OV329. This result builds upon prior clinical and preclinical ophthalmic safety characterization studies which demonstrated OV329 enters and then rapidly clears the brain, plasma and tissue, whereas vigabatrin, a first-generation GABA-AT inhibitor, was shown to preferentially partition and accumulate in the retina.
Phase 2 dose confirmatory & open-label proof-of-concept study
Ovid believes the drug exposure, PK, safety, and tolerability profile observed with the 5 mg and 7 mg doses of OV329 are supportive of further 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 study to evaluate the anti-seizure effect of OV329. In parallel, the Company is advancing plans for a Phase 2 randomized, placebo-controlled trial, which is expected to evaluate two dose levels and determine seizure reduction efficacy in people living with treatment-resistant FOS. Ovid is engaged in regulatory conversations and currently anticipates initiating the Phase 2 study in the second quarter of 2026.
OV329: New complementary development programs expanding into TSC seizures and IS
Ovid also announced plans to expand development of OV329 in TSC-associated seizures and IS, two rare and severe epileptic disorders characterized by significant unmet medical need.
GABA-AT inhibition is a clinically validated mechanism for the treatment of certain severe epilepsies, including TSC seizures and IS. The clinical utility of the first-generation GABA-AT inhibitor has been limited by safety concerns which constrain its broader use. Ovid believes OV329’s differentiated, next-generation profile may overcome these limitations, with the potential to unlock the full therapeutic benefit of GABA-AT inhibition for patients with severe pediatric epileptic disorders.
The Company is advancing a pediatric-specific formulation of OV329 amenable for infant and child use. For TSC-associated seizures, Ovid plans to initiate a proof-of-concept safety and signal-finding study in the fourth quarter of 2026 to evaluate OV329 in patients with TSC-associated seizures. In IS, the Company intends to initiate a safety and signal finding study in 2027.
These additive development programs are expected to proceed in parallel with the FOS program and may support an accelerated development pathway.
KCC2 portfolio: First clinical validation achieved; approval received for oral lead candidate OV4071 to enter the clinic in Australia
Ovid is advancing a proprietary portfolio of potential first-in-class direct activators of the potassium-chloride cotransporter 2 (KCC2), a CNS-specific target that is essential for synaptic inhibition and implicated in a broad range of neurological and neuropsychiatric disorders. Direct activation of KCC2 represents a mechanism-based approach to restoring inhibitory tone in the brain by regulating the efflux of chloride from neurons and thereby, enabling GABA to be hyperpolarizing (inhibitory). The Company is developing multiple molecules across the clinic and preclinic that have differentiated therapeutic profiles and formulations for potential conditions including psychoses, epilepsies, and neurodevelopmental and neurodegenerative disorders. The Company will be hosting an R&D Day dedicated to the KCC2 portfolio on April 14, 2026.
Key programs include:
- OV4071 (Oral KCC2 direct activator): OV4071, Ovid’s lead oral direct activator intended for chronic conditions, is proceeding to a Phase 1 clinical study in the second quarter of 2026 following receipt of HREC approval and acknowledgment of Ovid’s CTN from the Australian TGA. OV4071 is initially focused on psychosis associated with Parkinson’s disease and Lewy body dementia, both areas of significant unmet need with limited treatment options and established regulatory pathways. As part of the clinical development plan, Ovid intends to conduct a ketamine challenge study in mid-2026 to further characterize potential pharmacodynamic effects and establish proof-of-mechanism. Ovid believes OV4071 also has therapeutic potential across additional neuropsychiatric disorders characterized by neural circuit dysfunction, including schizophrenia and psychosis associated with Alzheimer’s disease, supporting broader expansion opportunities.
- OV350 (IV KCC2 direct activator): In December 2025, Ovid reported positive Phase 1 results demonstrating the first-ever clinical validation of direct KCC2 activation in humans. OV350 had no treatment-related serious adverse events reported and its PK behaved as predicted. Exploratory electrophysiology suggested OV350 had GABAergic CNS activity consistent with expected PK and the anticipated mechanism of action. These data support advancement of the Company’s oral KCC2 programs, including OV4071.
- KCC2 portfolio expansion: Ovid continues to advance additional oral and injectable KCC2 direct activators, including next-generation compounds, supporting a sustainable pipeline designed to unlock the full therapeutic potential of this novel mechanism across multiple indications.
BUSINESS STRATEGY AND UPDATES
The Company’s public announcement of HREC approval for OV4071 triggers a 30-day period for the exercise of the Company’s Series A Warrants to purchase up to 38,481,325 shares of the Company’s common stock and/or Pre-Funded Warrants to purchase common stock. Accordingly, the Series A Warrants will expire on April 17, 2026, if not exercised. If all Series A Warrants are exercised in full, the Company anticipates receiving up to an additional
On March 17, 2026, the Company entered into a Securities Purchase Agreement, pursuant to which the Company agreed to issue and sell an aggregate of 19,154,321 shares of its common stock at a purchase price of
The Company intends to use the proceeds from the Private Placement, together with its existing cash, cash equivalents and marketable securities to support the expansion of the development of OV329 into additional indications, including TSC and IS, alongside its ongoing development in FOS.
Multiple pipeline data and regulatory milestones are anticipated for Ovid’s OV329 epilepsy and KCC2 programs in the next 18 to 24 months. These anticipated milestones include: Phase 2 dose confirmatory study for OV329 in drug-resistant epilepsies (Q2 2026 start); initiation and completion of an open-label, patient proof-of-concept photo paroxysmal response study (Q3 2026 start), the potential initiation and completion of a proof-of-concept trial for the first oral KCC2 direct activator, OV4071 (Q2 2026 start); the initiation and results of a ketamine challenge study for OV4071 (mid-2026 start); and subsequently, the potential initiation and completion of Phase 1b studies for OV4071 in psychosis associated with Parkinson’s disease and Lewy body dementia, schizophrenia and other undisclosed indications.
