DeCure for Developmental and epileptic encephalopathy, 59
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for developmental and epileptic encephalopathy, 59 — 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, 59 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, 59 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
gamma-aminobutyric acid type B receptor subunit 2 (GABBR2) — GABBR2 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
Twenty-one children with epileptic encephalopathies received pulse intravenous methylprednisolone in a retrospective study. The responder rate, defined as more than 50% seizure reduction, was 85.7% at six and nine months of therapy, and 80.9% six months after treatment stopped. Genetic aetiology and encephalopathy related to status epilepticus during NREM sleep predicted efficacy. The fourth month of therapy was the earliest point to establish effectiveness. All patients showed improvements in quality of life, EEG tracing, and postural-motor development. No relevant adverse events were observed.
A systematic review of cannabidiol in children with developmental and epileptic encephalopathies included 13 studies with 656 children. Cannabidiol was given at a maximum dose of 50 mg/kg/day. Almost all studies reported positive outcomes, with at least 20% of patients achieving a 50% or greater reduction in seizure frequency in ten studies. Adverse events were relatively common and included somnolence, loss of appetite, diarrhoea, fatigue, and increased serum aminotransferases; most were mild to moderate and reversible. The review concluded that cannabidiol was well tolerated and effectively reduced seizure frequency in children whose seizures were uncontrolled with concomitant antiepileptic medications.
A review article on developmental and epileptic encephalopathy notes that the condition is driven mainly by genetic factors, typically begins in infancy or early childhood, and generally has a poor prognosis. Current therapeutic strategies include pharmacological treatments, nonpharmacological interventions, and emerging therapies such as gene and stem cell therapy. Another comprehensive review of epileptic encephalopathy states that significant challenges and limitations remain despite advances, and highlights the potential for personalised medicine to improve outcomes.
What is still missing are prospective, randomised controlled trials comparing these interventions against standard care or placebo, long-term follow-up data on developmental outcomes and quality of life beyond seizure counts, and validated biomarkers to stratify patients by genetic aetiology or EEG pattern before treatment. The methylprednisolone study is retrospective and uncontrolled; the cannabidiol review notes that most included studies were not blinded. No trial has yet addressed whether seizure reduction translates into sustained cognitive or motor gains.

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.

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.

Efficacy and safety of cannabidiol in children with developmental and epileptic encephalopathies: A systematic review
AbstractDevelopmental and epileptic encephalopathies constitute rare epileptic conditions characterized by treatment-resistant seizures, neurodevelopmental delays, and various comorbidities. None of the currently available drugs succeeded in suppressing the epileptiform activity in those conditions. Cannabidiol has been used as a novel treatment strategy in patients with treatment-resistant epilepsies. We aimed to assess the efficacy and safety of cannabidiol in children with developmental and epileptic encephalopathies through a systematic review. For this systematic review, we searched MEDLINE, Cochrane Central Register of Controlled Trials, trial registries, and reference lists of included studies. All types of studies of pharmaceutical cannabidiol in children with developmental and epileptic encephalopathies were eligible, and we did not set any language or date restrictions. The risk of bias in included studies was assessed using validated tools. Of the 683 records identified, 13 were eligible for inclusion in this review. Studies were of different types and included a total of 656 children with developmental and epileptic encephalopathies. Cannabidiol was administered at a maximum 50mg/kg/day dose. Almost all studies reported positive outcomes with cannabidiol, leading to a reduction of 50% or above in seizure frequency in at least 20% of patients included in 10 studies. Adverse events were relatively common across studies and included somnolence, loss of appetite, diarrhea, fatigue, and increased serum aminotransferases. Most of them were mild to moderate and reversible. Overall, cannabidiol was found to be well tolerated and to effectively reduce seizure frequency in children with developmental and epileptic encephalopathies experiencing seizures uncontrolled with concomitant antiepileptic medications. Future research should investigate the long-term effects of cannabidiol not only in seizure control but also in enhancing the development and quality of life of affected children.
