(NASDAQ: OVID), a biopharmaceutical company dedicated to meaningfully improving the lives of people affected by rare epilepsies and brain conditions, today reported business updates and financial results for the fourth quarter and year ended December 31, 2023. “Ovid is progressing well and we are excited. This year we anticipate five clinical and regulatory milestones from our pipeline of novel compounds. Our ROCK2 collaboration with Graviton Bioscience is producing results faster than expected. We look forward to initiating a Phase 2 study of OV888 (GV101) in cerebral cavernous malformations (CCM) in the second half of this year. By year end 2024, we expect to deliver biomarker data from our oral OV329 program and investigational new drug submissions for intravenous formulations of both OV329 and OV350,” said Dr. Jeremy Levin, D. Phil, MB Chir, Chairman and CEO of Ovid. “Importantly, the first potential rare epilepsy medicine that Ovid helped shape, soticlestat, is expected to have two pivotal Phase 3 study topline readouts by Takeda. If the trials are successful, we believe a new and important medicine will be available to LGS and DS patients in 2025. If approved and successfully commercialized, Ovid will be eligible to receive regulatory and sales milestone payments as well as royalties on all future sales of soticlestat,” Dr. Levin added. Pipeline Updates Ovid anticipates five clinical and regulatory milestones this year from its own pipeline. In addition, Takeda is expected to read out results from two pivotal Phase 3 studies evaluating soticlestat. Soticlestat: Enrollment is complete for two pivotal Phase 3 trials studying soticlestat for Lennox-Gastaut syndrome and Dravet syndrome. Takeda reported that it anticipates Phase 3 data readouts for both trials by or before September 2024 and regulatory filings for soticlestat by or before March 31, 2025. Ovid co-developed soticlestat with Takeda through the completion of Phase 2 studies and subsequently sold its rights back to Takeda. Ovid retains significant financial interest in soticlestat. If soticlestat is approved and commercialized, Ovid is eligible to receive regulatory and commercial milestone payments of up to $660 million, as well as tiered low double-digit royalties up to 20% on global net sales from Takeda. Of these potential future payments, Ovid sold a 13% interest to Ligand Pharmaceuticals for $30 million in October 2023. Ovid retains 87% of its interest in any milestone payments and royalties and has no ongoing obligations or costs associated with the development of soticlestat. OV888 (GV101): Ovid and its collaborator Graviton Bioscience are currently progressing the study of OV888 (GV101) in a Phase 1 multiple-ascending dose study, which is expected to complete in the first half of 2024. No serious adverse events have been observed and a higher dose cohort has been added. OV888 (GV101) is a highly selective ROCK2 inhibitor for the potential treatment of CCM and other rare neurological conditions. Ovid and Graviton Bioscience expect to initiate a Phase 2 efficacy and safety study of OV888 (GV101) in patients living with CCM in the second half of 2024. Additionally, Ovid and Graviton Bioscience amended their collaboration agreement. Ovid paid $2.2 million to obtain an advanced gelcap formulation of OV888 (GV101), thereby enabling the acceleration of the development timeline toward Phase 2 trials. OV329: Ovid continues to advance two development programs for OV329, a potential next generation GABA-aminotransferase (GABA-AT) inhibitor. Both programs are anticipated to have milestones this year. Oral formulation An oral formulation of OV329 for the potential treatment of chronic seizures is being actively evaluated in a Phase 1 safety study, which includes surrogate biomarkers to measure target engagement and clinical efficacy. No safety signals were seen in single-ascending dose cohorts. The multiple-ascending dose study is designed to use magnetic resonance spectrometry and transcranial magnetic stimulation as biomarkers. This biomarker design is reinforced by preclinical data that Ovid presented at the American Epilepsy Society 2023 annual meeting. This preclinical data demonstrates that OV329 elicits an electroencephalogram response which is a potential pharmaco-dynamic marker of anti-convulsant activity. Data is expected from the Phase 1 study in late 2024, as is further preclinical data characterizing OV329's safety profile relative to vigabatrin.Intravenous (IV) formulationAn IV formulation of OV329 for potential treatment of acute seizures is on track for an anticipated IND application or an equivalent regulatory application by late 2024. The IV formulation is supported by emerging evidence that GABA-AT inhibition may be effective in the treatment of status epilepticus. Potassium chloride co-transporter 2 (KCC2) direct activator portfolio and OV350: Findings from several preclinical disease models indicate that Ovid's portfolio of KCC2 direct activator compounds hold therapeutic promise in multiple indications, including in seizures and psychosis. The initial program from the portfolio, which is an IV formulation of OV350, is anticipated to submit an IND by year-end 2024. In addition to OV350, Ovid is conducting non-clinical studies to characterize multiple compounds from its library of direct activators of KCC2 to assess them for therapeutic and formulation potential.Non-epilepsy indications for KCC2 direct activators may represent future collaborative development opportunities for Ovid. General Corporate & Business Updates Financial runway: Ovid anticipates its cash runway will support operations and clinical development programs into the first half of 2026. Ovid also anticipates several events for its current pipeline programs and clinical results for soticlestat from Takeda in 2024. To manage its capital resources, the Company leadership has executed several steps. For example, Ovid received $30 million of non-dilutive capital from Ligand in exchange for 13% of Ovid's interest in soticlestat’s potential future milestone payments and royalties. This capital is being directed toward anticipated high-value research and development activities.Ovid retains 87% of its interest in soticlestat’s future milestones and royalties, which is not reflected in its current runway guidance. If successfully commercialized, this may provide significant non-dilutive capital to further fund Ovid and its pipeline. Scientific strategy: Ovid is focused on the development of novel, targeted small molecules that have the potential to be first-in-class or best-in-class neurotherapeutics. The mechanisms of action in Ovid’s pipeline modulate extrinsic or intrinsic causes of neuronal hyperexcitability and function by acting on neurotransmitters, vascular structure causes of seizures or physiological properties within neurons. Hyperexcitability is implicated in many neurological indications, including seizures, psychiatric conditions, neurodevelopmental and neurodegenerative diseases, thus underscoring a broader therapeutic opportunity for Ovid’s pipeline assets.Business development activities: Ovid’s future business development efforts are focused on: exploring out-licensing opportunities for its genetic programs and elements of its patent estate that are not needed for Ovid's internal programs; potential collaborations to advance development opportunities for its KCC2 portfolio in non-core indications; and the exploration of commercial opportunities for some of its programs in territories outside the United States.
