DeCure for Developmental and epileptic encephalopathy, 28
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for developmental and epileptic encephalopathy, 28 — screening already-approved drugs against its 1-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.
Disease moduleDevelopmental and epileptic encephalopathy, 28 maps to a 1-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead
No approved-drug candidate for developmental and epileptic encephalopathy, 28 is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.
What the evidence adds up to
The term developmental and epileptic encephalopathy (DEE) describes a group of heterogeneous disorders where cognitive function is influenced by both seizure activity and the underlying neurobiological process. Many DEEs are linked to gene variants, with onset typically in early childhood. A 2021 review distinguishes DEE from developmental encephalopathy (DE), where epileptiform activity has minimal effect on function, and epileptic encephalopathy (EE), where cognition is directly impacted by epileptic activity and may improve with appropriate intervention. The same review notes that patients with DEE might benefit from a precision medicine approach to reduce the overall burden of epilepsy, while those with DE are unlikely to gain from aggressive antiseizure medication. A 2015 article states that cognitive outcomes in epileptic encephalopathy are hypothesised to result from an interplay between the underlying epileptic pathology and the acquired consequences of frequent seizures, but presents this as an assumption requiring further evidence.
A 2015 study identified cyclin-dependent kinase-like 5 (CDKL5) mutations in five Japanese patients (one male, four female) with epileptic encephalopathy; all mutations were de novo and located at positions previously reported as pathogenic, suggesting possible hot spots for nucleotide alteration. A 2024 review states that DEE is mainly driven by genetic factors, typically with onset in infancy or early childhood and generally a poor prognosis. A 2025 review notes that although individually rare, DEEs constitute a sizeable group of paediatric epilepsies and emphasises the importance of recognising treatable or modifiable entities.
A 2021 retrospective study examined brivaracetam in eight paediatric patients (≤14 years) with epileptic encephalopathy or refractory focal epilepsy. All patients showed at least a 50% reduction in seizure frequency: 37.5% became seizure-free, 25% had a reduction of ≥75%, and 37.5% had a reduction of ≥50%. All patients with epilepsy onset after 12 months and epilepsy duration of six years or less became seizure-free. The maximum effect was achieved at 2 mg/kg/day, and focal seizures responded better than epileptic encephalopathy. A positive effect was noted in patients with encephalopathy regarding status epilepticus during sleep. No relevant side-effects were reported. The study excluded patients taking levetiracetam and those with progressive cerebral disease, tumour, or progressive neurodegenerative disease. A 2013 article states that treatment options for epileptic encephalopathy are very limited, that diagnostic criteria are not well developed, and that clinicians are often unable to diagnose even benign epileptic syndromes.
What is still missing are large, prospective trials that stratify patients by genetic aetiology, age at onset, and epilepsy duration. The brivaracetam study is retrospective, includes only eight patients, and excludes those on levetiracetam, limiting generalisability. No randomised controlled trial data exist for most DEE syndromes. Funding for multi-centre, genetically informed trials and for the development of validated diagnostic criteria remains inadequate.

Developmental and epileptic encephalopathies: recognition and approaches to care
AbstractThe term "developmental and epileptic encephalopathy" (DEE) refers to when cognitive functions are influenced by both seizure and interictal epileptiform activity and the neurobiological process behind the epilepsy. Many DEEs are related to gene variants and the onset is typically during early childhood. In this setting, neurocognition, whilst not improved by seizure control, may benefit from some precision therapies. In patients with non-progressive diseases with cognitive impairment and co-existing epilepsy, in whom the epileptiform activity does not affect or has minimal effect on function, the term "developmental encephalopathy" (DE) can be used. In contrast, for those patients with direct impact on cognition due to epileptic or epileptiform activity, the term "epileptic encephalopathy" (EE) is preferred, as most can revert to their normal or near normal baseline cognitive state with appropriate intervention. These children need aggressive treatment. Clinicians must tailor care towards individual needs and realistic expectations for each affected person; those with DE are unlikely to gain from aggressive antiseizure medication whilst those with EE will gain. Patients with DEE might benefit from a precision medicine approach in order to reduce the overall burden of epilepsy.
Epileptic encephalopathies: Optimizing seizure control and developmental outcome
AbstractCognitive and developmental outcomes in patients with epileptic encephalopathy are hypothesized to result from an interplay between the underlying epileptic pathologic substrate and the acquired consequences of frequent and repetitive seizures and epileptiform discharges that often straddle the interictal and ictal boundaries. This article briefly reviews the evidence related to this assumption, presents critical questions that need to be answered to clarify this relationship, and advances a set of concrete steps that may help improve developmental patient outcomes.

Recurrent occurrences of CDKL5 mutations in patients with epileptic encephalopathy
AbstractThe cyclin-dependent kinase-like 5 gene (CDKL5) is recognized as one of the genes responsible for epileptic encephalopathy. We identified CDKL5 mutations in five Japanese patients (one male and four female) with epileptic encephalopathy. Although all mutations were of de novo origin, they were located in the same positions as previously reported pathogenic mutations. These recurrent occurrences of de novo mutations in the same loci may indicate hot spots of nucleotide alteration.
Brivaracetam in treating epileptic encephalopathy and refractory focal epilepsies in patients under 14 years of age.
AbstractOBJECTIVES: To analyze the efficacy and safety of Brivaracetam in pediatric patients with epileptic encephalopathy or unresponsive focal epilepsy. MATERIALS & METHODS: This retrospective study included eight pediatric patients with EE or unresponsive focal epilepsy. Inclusion criteria: (1) ≤14 years, (2) history of refractory epilepsy, (3) at least one month of continuous therapy with BRV, and (4) at least six months of follow-up. Exclusion criteria: (1) variation of concomitant antiepileptic drugs during the previous and/or subsequent four weeks of the BRV introduction, (2) levetiracetam in therapy, (3) epilepsy secondary to the progressive cerebral disease, tumor, or any other progressive neurodegenerative diseases, and (4) a status epilepticus a month before screening or during the baseline period. The efficacy of BRV was defined as ≥50% of seizure frequency reduction at the end of the follow-up, compared to baseline. RESULTS: All patients showed ≥50% seizure frequency reduction, of whom 37.5% were seizure-free, 25% had a frequency reduction of ≥75%, and 37.5% had frequency reduction of ≥ 50%. All patients with an epilepsy onset >12 months and epilepsy duration of ≤6 years were seizure-free. The maximum effect was achieved at 2 mg/kg/day, and focal seizures revealed a better response than epileptic encephalopathy. A remarkably positive effect of the Brivaracetam was noticed in patients with encephalopathy regarding the status epilepticus during sleep; however, no relevant side-effects were noted. CONCLUSION: Brivaracetam was an effective and well-tolerated treatment in pediatric patients with epileptic encephalopathy or unresponsive focal epilepsy, especially for the epilepsy onset >12 months and the epilepsy duration ≤6 years. The total effect was not dose-dependent. Brivaracetam could represent an indication of encephalopathy regarding the status epilepticus during sleep.

Developmental and Epileptic Encephalopathies: Progress in Understanding and Clinical Implications
AbstractAbstract Developmental and epileptic encephalopathies (DEEs) are a group of complex pediatric epilepsies associated with adverse neurodevelopmental outcomes and multiaxial neurological morbidities. The understanding of DEE has evolved from its initial genetic underpinnings, to a clinically driven term encompassing a broader group of etiologies. Although individually rare, the DEEs constitute a sizeable group of pediatric epilepsies. It is especially important to recognize treatable or modifiable entities in this group. This review attempts to highlight the progress in understanding, along with the evolution of the conceptual framework of DEEs. A summary of the currently well-established DEE syndromes is provided along with available precision therapies, which might help the treating physician in the appropriate evaluation and management of the affected children.

Research progress on developmental and epileptic encephalopathy
AbstractDevelopmental and epileptic encephalopathy (DEE) is a group of heterogeneous disorders characterized by drug-resistant seizures and neurodevelopmental delay, which can hinder brain development and lead to severe cognitive, behavioral, and motor impairments. DEE is mainly driven by genetic factors, typically with an onset in infancy or early childhood and generally with an overall poor prognosis. This article provides a review of the definition, epilepsy syndromes, genetic etiology, and precision treatment of DEE.

On the Clinics and Diagnosis of Epileptic Encephalopathy
AbstractEarly childhood is characterized by a continuous process of development of structures and functions of organism, especially central nervous system.The concept of epileptic encephalopathy is based on the assumption that the aggressive epileptic activity during the maturation of the brain is the main causal factor in cognitive and neuropsychological impairment or regress. With age, EEG signs of evolving consistent with the transition into each another. Currently the diagnosis criteria are not well developed and the treatment options are very limited, whereby patients cannot receive adequate treatment that further aggravates encephalopathy. Unfortunately clinicians are often unable to diagnose also benign epileptic syndromes.
