DeCure for Developmental and epileptic encephalopathy, 84
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for developmental and epileptic encephalopathy, 84 — 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, 84 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, 84 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.
Molecular view
UDP-glucose 6-dehydrogenase (UGDH) — UGDH is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to
In a retrospective study of 21 paediatric patients with epileptic encephalopathy who received pulse intravenous methylprednisolone (IVMP), the responder rate (seizure reduction greater than 50%) was 85.7% at 6 and 9 months of therapy, and 80.9% at 6 months after therapy suspension. Genetic aetiology and encephalopathy related to status epilepticus during NREM sleep (ESES) were predictive of efficacy (p=0.0475). The fourth month of therapy was the minimum time point to establish effectiveness. All patients showed improvements in quality of life, EEG tracing and postural-motor development. No relevant adverse events were observed.
The broader category of developmental and epileptic encephalopathy (DEE) is defined by cognitive impairment driven by both seizure activity and the underlying neurobiological process. Many DEEs are linked to gene variants with onset in early childhood. The distinction between developmental encephalopathy (DE), where epileptiform activity has minimal effect on function, and epileptic encephalopathy (EE), where cognition is directly impaired by epileptic activity, is considered clinically important. Patients with DE are described as unlikely to gain from aggressive antiseizure medication, while those with EE are expected to benefit. A precision medicine approach is suggested for DEE to reduce the overall burden of epilepsy.
The understanding of DEE has evolved from initial genetic underpinnings to a broader clinical term encompassing multiple aetiologies. Although individually rare, DEEs constitute a sizeable group of paediatric epilepsies. Recognising treatable or modifiable entities is emphasised. Current therapeutic strategies include pharmacological treatments, nonpharmacological interventions, and emerging therapies such as gene and stem cell therapy, though significant challenges and limitations remain. One case report describes a child whose epilepsy evolved from treatment-responsive focal epilepsy to treatment-resistant focal epilepsy with epileptic encephalopathy between 18 months and 3 years, illustrating poorly understood age-related changes in seizure susceptibility and drug responsiveness.
What is still missing are large, prospective, controlled trials that confirm the IVMP findings in broader DEE populations, particularly with standardised outcome measures beyond seizure reduction. The retrospective IVMP study had only 21 patients and no control group. The field lacks validated biomarkers to distinguish DE from EE at the bedside, and the genetic heterogeneity of DEE makes trial design and patient stratification difficult. Funding for such trials, especially for rare genetic subtypes, remains limited.

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.

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.
Efficacy and Safety of Pulse Intravenous Methylprednisolone in Pediatric Epileptic Encephalopathies: Timing and Networks Consideration
AbstractAbstract: Background: epileptic encephalopathies (EE) are characterized by severe drug-resistant seizures, early-onset, and unfavorable developmental outcome. We describe a cohort of pediatric patients with EE who underwent intravenous methylprednisolone (IVMP) pulse therapy to examine its efficacy/tolerability. Methods: This is a retrospective study from 2020 to 2023. Inclusion criteria were: ≤18 years at the time of IVMP pulse therapy and at least 6 months of follow-up. Efficacy and outcome, defined as seizure reduction >50% (responder rate), were evaluated at 6 and 9 months of therapy, and 6 months after therapy suspension; quality of Life (QoL) was also assessed. Variables predicting positive post-IVMP outcomes were identified using statistical analysis. Results: Twenty-one patients were included. The responding rate was 85.7% at 6 and 9 months of therapy, and 80.9% at 6 months after therapy suspension. Genetic etiology and encephalopathy related to status epilepticus during NREM sleep (ESES) were predictive of efficacy (p=0.0475). The fourth month of therapy was the minimum time point to establish the effectiveness of the treatment. All patients showed improvements in QoL, EEG tracing and postural-motor development. No relevant adverse events were observed. Conclusions: Our study confirms the efficacy and tolerability of pulse IVMP treatment in pediatric patients with EE, especially with genetic etiology and ESES. The fourth month of therapy was the minimum time point to establish its effectiveness. QoL, EEG and postural-motor development also showed improvement.
A Child with Epilepsy: Initial Presentation and Subsequent Course
AbstractPresented is the case of a child with epilepsy with dramatic evolution between the ages of 18 months and 3 years. Initially, the case is one of treatment-responsive focal epilepsy, but then evolves to treatment-resistant focal epilepsy with an epileptic encephalopathy. The case demonstrates the poorly understood entities of age-related changes in seizure suspectibility, seizure types, and drug responsiveness.

DRUG RESISTANT EPILEPTIC ENCEPHALOPATHY WITH LATE-ONSET SPASMS
AbstractDevelopmental and epileptic encephalopathy (DEE) is a term used to describe cerebral dysfunction resulting from the underlying cause, epilepsy, or both. There is a subset of DEEs in which there is compelling evidence that the regression is directly tied to the epilepsy itself, where the “epileptic encephalopathy” component of DEE is most evident. Infantile epileptic spasm syndrome (IESS) is perhaps the clearest example.
