DeCure for Developmental and epileptic encephalopathy, 36
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for developmental and epileptic encephalopathy, 36 — 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, 36 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, 36 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 conditions where cognitive function is affected both by the underlying genetic or acquired cause and by frequent seizure and interictal epileptiform activity. Onset is typically in early childhood. A 2021 review distinguishes DEE from developmental encephalopathy (DE), where epileptiform activity has minimal effect on function and aggressive antiseizure medication is unlikely to help, and from epileptic encephalopathy (EE), where cognition is directly impaired by epileptic activity and can often revert to near normal with appropriate intervention. Patients with DEE might benefit from a precision medicine approach to reduce the overall burden of epilepsy, but the review does not report any specific drug trial results.
A 2016 study used in silico prioritisation based on gene coexpression in human brain data to rank candidate genes for epileptic encephalopathy. Of 179 candidates evaluated in 2013, 6 had been validated by the time of the study; 5 of those 6 were among the 19 genes the 2013 analysis had prioritised (odds ratio 54, p = 4.5 × 10⁻⁵). The genome-wide analysis then identified 297 genes ranked in the top 10% for coexpression with a reference set of 51 established epileptic encephalopathy genes in both adult and developing brain data. Nine of those 297 had already been implicated in epileptic encephalopathy by de novo variant studies: FBXO41, PLXNA1, ACOT4, PAK6, GABBR2, YWHAG, NBEA, KNDC1, and SELRC1. The study proposes these as strong candidates for further investigation but does not report any treatment outcomes.
A 2023 study from a reference centre in Northeast Brazil notes that by August 2022, 105 genes were associated with DEE according to OMIM. A 2020 case report describes cerebrospinal fluid abnormalities in a patient with a de novo CDK19 variant but provides no treatment data. A 2023 review of childhood epilepsy states that many children develop pharmacoresistant epilepsy beginning in early infancy and progress to DEE with intellectual, behavioural, or motor disabilities; these children do not show remission and require comprehensive medical care into adulthood. The same review notes that childhood epilepsy syndromes are categorised into a self-limited group with good prognosis and a pharmacoresistant group with poor prognosis despite low prevalence rates.
No abstract reports a completed clinical trial of any drug for DEE specifically. The 2021 review mentions precision therapies as a potential benefit but gives no concrete efficacy numbers, survival data, or response rates. What is still missing are randomised controlled trials with sufficient sample sizes, validated biomarkers to stratify patients by genetic subtype, and funding to move from gene discovery and in silico prioritisation to interventional studies.

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.

In silico prioritization based on coexpression can aid epileptic encephalopathy gene discovery
AbstractOBJECTIVE: To evaluate the performance of an in silico prioritization approach that was applied to 179 epileptic encephalopathy candidate genes in 2013 and to expand the application of this approach to the whole genome based on expression data from the Allen Human Brain Atlas. METHODS: PubMed searches determined which of the 179 epileptic encephalopathy candidate genes had been validated. For validated genes, it was noted whether they were 1 of the 19 of 179 candidates prioritized in 2013. The in silico prioritization approach was applied genome-wide; all genes were ranked according to their coexpression strength with a reference set (i.e., 51 established epileptic encephalopathy genes) in both adult and developing human brain expression data sets. Candidate genes ranked in the top 10% for both data sets were cross-referenced with genes previously implicated in the epileptic encephalopathies due to a de novo variant. RESULTS: Five of 6 validated epileptic encephalopathy candidate genes were among the 19 prioritized in 2013 (odds ratio = 54, 95% confidence interval [7,∞], p = 4.5 × 10(-5), Fisher exact test); one gene was false negative. A total of 297 genes ranked in the top 10% for both the adult and developing brain data sets based on coexpression with the reference set. Of these, 9 had been previously implicated in the epileptic encephalopathies (FBXO41, PLXNA1, ACOT4, PAK6, GABBR2, YWHAG, NBEA, KNDC1, and SELRC1). CONCLUSIONS: We conclude that brain gene coexpression data can be used to assist epileptic encephalopathy gene discovery and propose 9 genes as strong epileptic encephalopathy candidates worthy of further investigation.

Cerebrospinal fluid abnormalities in developmental and epileptic encephalopathy with a <i>de novo CDK19</i> variant
AbstractDevelopmental and epileptic encephalopathy (DEE) is a spectrum of neurodevelopmental conditions in which psychomotor delay or regression arises in association with frequent epileptic activity. In the past decade, molecular genetics studies showed that DEE is caused by environmental insults and by genetic factors; several de novo pathogenic variants were also identified.1 The authors are indebted to the patient and her parents. The authors would also like to thank Enago ([enago.jp][1]) for the English language review. [1]: http://www.enago.jp/
AbstractChildhood epilepsy is characterized by specific epilepsy syndromes that occur during each developmental age. These "age-dependent" epilepsy syndromes are clinically categorized into a self-limited epilepsy group with good prognosis and high prevalence rate and a pharmacoresistant epilepsy group with poor prognosis despite low prevalence rates. Many children develop pharmacoresistant epilepsy beginning in early infancy and progress to developmental epileptic encephalopathy, which is associated with intellectual, behavioral, and/or motor disabilities. These children do not show remission in epilepsy and are transitioned to the adult service and require comprehensive medical care.

Genetic profile of patients with developmental and epileptic encephalopathy at a reference center in Northeast Brazil
AbstractBackground: The developmental and epileptic encephalopathy (DEE) diseases where there is developmental impairment related to both the underlying etiology independent of epileptiform activity and the epileptic encephalopathy. Many DEEs have a genetic basis that, by themselves, can alter the neurodevelopmental delay. By August 2022, there were 105 genes associated with DEE according to OMIM.
