Ovid Therapeutics Announces Initiation of Two Phase 2 Clinical Trials of OV935/TAK-935 for Pediatric Patients with Rare Epilepsies
-- OV935 is being investigated for the treatment of pediatric patients with Dravet or Lennox-Gastaut syndromes in the ELEKTRA trial and pediatric patients with CDKL5 deficiency or Dup15q syndromes in the ARCADE trial --
The Phase 2 ELEKTRA trial is a multi-center, randomized, double-blind, placebo-controlled, parallel-design, clinical trial of OV935 in pediatric patients with Dravet syndrome or Lennox-Gastaut syndrome (LGS). The trial is expected to enroll 126 patients aged 2 to 17 years old at clinical sites worldwide. The Phase 2 ARCADE trial is a multi-center, open-label, pilot study of OV935 in pediatric patients with CDKL5 deficiency disorder (CDD) or Duplication 15q (Dup15q) syndrome. Approximately 30 total patients – 15 children with each condition – aged 2 to 17 years old are expected to be enrolled. Each study will assess the effects of OV935 on efficacy, safety and tolerability.
OV935 is a potent, highly-selective, first-in-class inhibitor of the enzyme cholesterol 24-hydroxylase (CH24H) that is being investigated as an anti-epileptic drug (AED) in a range of developmental and epileptic encephalopathies (DEE). DEE is a term for a specific group of rare epilepsy conditions that typically present early in life and are often associated with severe cognitive and developmental impairment in addition to frequent treatment-resistant seizures throughout the person’s lifetime. These disorders vary in age of onset, developmental outcomes, etiologies, neuropsychological deficits, electroencephalographic (EEG) patterns, seizure types and prognosis.
“Ovid understands the importance and need of bringing novel and potentially transformative medicines to people with DEE as quickly and early as possible,” said

About the ELEKTRA Trial
ELEKTRA is an international Phase 2, multi-center, randomized, double-blind, placebo-controlled study that will evaluate the treatment of OV935 in pediatric patients, aged 2 to 17 years old, with epileptic seizures associated with Dravet syndrome or LGS. The study consists of a four to six week screening period to establish baseline seizure frequency followed by a 14-week treatment period that includes a 2-week dose titration period and a 12-week maintenance period. The primary endpoint is the change from baseline in seizure frequency in patients treated with OV935 compared to placebo by disorder (Dravet, LGS). The secondary endpoints include safety, tolerability and pharmacokinetic (PK) assessments as well as the percentage of patients considered treatment responders, changes in Clinician’s Clinical Global Impressions of Severity and Change (CGI-S/C) and correlation of OV935 concentration with plasma 24S-hydroxycholesterol (24HC) levels.
ELEKTRA is expected to enroll 126 pediatric patients at approximately 45 clinical trial sites in
About the ARCADE Trial
ARCADE is a Phase 2, multi-center, open-label, pilot study that will evaluate the treatment of OV935 in pediatric patients, aged 2 to 17 years old, with epileptic seizures associated with CDD or Dup15q syndrome. The primary endpoint is the change in motor seizure frequency in patients treated with OV935 by disorder (CDD and Dup15q). The key secondary endpoints include safety and tolerability, including percentage of participants considered treatment responders, change in CGI-S/C and correlation of OV935 concentration and plasma 24HC levels.
ARCADE is expected to enroll approximately 15 children with each condition at clinical trial sites in
About the Rare DEE being studied by Takeda and Ovid
Cyclin-Dependent Kinase-Like 5 (CDKL5) Deficiency Disorder (CDD)
Cyclin-Dependent Kinase-Like 5 (CDKL5) deficiency disorder, also known as CDD, is an ultra-rare, severe, neurological disorder caused by mutations in the CDKL5 gene on the X-chromosome. The CDKL5 gene provides instructions for making a protein that is essential for normal brain and neuron development, and may play a role in regulating the activity of other genes. CDD causes early onset and treatment resistant epilepsy in infants 3 to 6 months of age. Other common features of CDD include severe developmental delay and intellectual disability, poor fine motor skills, difficulty sleeping, scoliosis, visual impairment, microcephaly and various gastrointestinal difficulties.
Duplication 15q (Dup15q) Syndrome
Duplication 15q syndrome, also known as Dup15q syndrome, is a rare, severe, neurological disorder that results from duplications of chromosome 15q11.2-q13.1. In most cases, the chromosome mutation is not inherited but occurs during formation of reproductive cells or during embryonic development. Those with Dup15q syndrome experience seizures, hypotonia (poor muscle tone), developmental delays and intellectual disability. Difficult to control seizures are the most devastating symptom of Dup15qii. The severity of Dup15q and associated symptoms varies based on the size and location of the duplication and which genes are involved. There is insufficient demographic data to determine the prevalence of Dup15q in the general population.
Dravet syndrome is a severe form of childhood epilepsy that typically presents during the first year of life. It is believed to be largely caused by mutations in the SCN1A gene. Children experience frequent seizures, loss of muscle control, cognitive deficits and, in approximately 10 percent of cases, death before the age of 12 years. While some individuals may survive into adulthood, their long-term intellectual development and seizure outcomes are typically extremely poor. The incidence of Dravet syndrome in
Lennox-Gastaut syndrome is one of several disorders that together are designated as DEE.iv Patients diagnosed with LGS experience multiple seizure types that are difficult to manage and have many of the same symptoms as other rare pediatric epilepsies. Studies estimate that LGS affects approximately 14,500 to 18,500 children under the age of 18 and over 30,000 children and adults in
About Investigational OV935/TAK-935
OV935/TAK-935 is a potent, highly-selective, first-in-class inhibitor of the enzyme cholesterol 24-hydroxylase (CH24H) being investigated as an anti-epileptic drug (AED). CH24H is predominantly expressed in the brain, where it plays a central role in cholesterol homeostasis. CH24H converts cholesterol to 24-hydroxycholesterol (24HC), which then exits the brain into the blood plasma circulation. Glutamate is one of the main neurotransmitters in the brain and has been shown to play a role in the initiation and spread of seizure activity. Recent literature indicates CH24H is involved in over-activation of the glutamatergic pathway through modulation of the NMDA channel, implying its potential role in central nervous system diseases such as epilepsy. Ovid and Takeda believe that OV935’s novel mechanism of action may potentially treat rare epilepsies by inhibiting CH24H to decrease 24HC levels, effectively decreasing glutamate hyperactivity. To Ovid and Takeda’s knowledge, OV935 is the only molecule with this mechanism of action in clinical development. OV935 is an investigational drug, not approved for commercial use.
OV935 has successfully completed four Phase 1 clinical studies, which have assessed tolerability, PK and target engagement at doses believed to be therapeutically relevant. In preclinical models, a novel proprietary PET ligand was used to determine target occupancy of OV935 in the brain. OV935 is being co-developed by Ovid and Takeda Pharmaceutical Company Limited.
Enrollment is complete in the Phase 1b/2a randomized, double-blind, clinical trial designed to look at the safety, tolerability, PK, and pharmacodynamics of OV935 in adult patients with DEE. Topline data from the trial are expected in the fourth quarter of 2018.
