DeCure for Developmental and epileptic encephalopathy, 35
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for developmental and epileptic encephalopathy, 35 — 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, 35 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, 35 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
inosine triphosphatase (ITPA) — ITPA 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
CDKL5 mutations were found 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 mutation hot spots. A 2020 report describes a patient with DEE and a de novo CDK19 variant, but provides no efficacy data for any drug. A 2023 study notes that by August 2022, 105 genes were associated with DEE according to OMIM, but gives no treatment outcomes.
A 2025 systematic review of cannabidiol in children with DEE included 13 studies and 656 children. Cannabidiol was given at a maximum dose of 50 mg/kg/day. In 10 of the 13 studies, at least 20% of patients achieved a 50% or greater reduction in seizure frequency. Adverse events were common: somnolence, loss of appetite, diarrhoea, fatigue, and increased serum aminotransferases; most were mild to moderate and reversible. The review concludes that cannabidiol was well tolerated and effectively reduced seizure frequency in children whose seizures were uncontrolled with other antiepileptic drugs. A 2024 review article summarises the definition, genetic aetiology, and precision treatment of DEE but provides no new trial data.
What is still missing: long-term data on cannabidiol’s effects on development and quality of life, prospective trials that stratify patients by specific genetic variants (such as CDKL5 or CDK19), and funding for trials that go beyond seizure-count endpoints to measure cognitive and behavioural outcomes.

The efficacy of bromides, stiripentol and levetiracetam in two patients with malignant migrating partial seizures in infancy
AbstractThe syndrome of malignant migrating partial seizures in infancy is a devastating, age-specific, epileptic encephalopathy, which still presents an aetiological, pathophysiological and therapeutic problem. In this study, we present two patients who were diagnosed with the disease, based on electroclinical symptoms. The patients were treated with a combination of sodium bromide, stiripentol and levetiracetam. The first patient unequivocally responded, following a course of ineffective conventional drugs, and the second, who was diagnosed and treated immediately, showed a more significant therapeutic response. Antiepileptic drugs, previously reported to be beneficial in case reports, when given concomitantly, may substantially reduce the number and severity of seizures, without influence on psychomotor development.

A Treatable Genetic Disease Caused by CAD Mutation
AbstractType 50 early infantile epileptic encephalopathy, or EIEE-50 for short, is an autosomal recessive genetic disorder resulting from CAD mutations. So far, little has been reported on the disease. In this article, we will discuss the case of a male infant who is 8 years and 5 months old. A whole-exome sequencing of the boy revealed CAD compound heterozygous mutations. He suffered from global developmental delay and regression, refractory epilepsy, and anemia. After his diagnosis, we used uridine treatment and gained encouraging results. In this article, we will analyze our case studies in the context of the literature, so as to improve pediatricians' understanding of the disease.

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.

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/

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.

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.
