Infantile Spasms syndrome (ISs) is a characterized by epileptic spasms occurring in clusters with an onset in the first year of life. West syndrome represents a subset of ISs that associates spasms in clusters, a hypsarrhythmia EEG pattern and a developmental arrest or regression. Aetiology of ISs is widely heterogeneous including many genetic causes. Many patients, however, remain without etiological diagnosis, which is critical for prognostic purpose and genetic counselling. In the present study, the investigators performed genetic screening of 73 patients with different types of ISs by array-CGH and molecular analysis of 5 genes: CDKL5, STXBP1, KCNQ2, and GRIN2A, whose mutations cause different types of epileptic encephalopathies, including ISs, as well as MAGI2, which was suggested to be related to a subset of ISs.
The sponsor is developing a new paediatric formulation of vigabatrin to better adjust the dose to body weight and to limit waste of unused drug. The currently marketed vigabatrin (Sabril™) form only exists as 500 mg film coated tablets (for adults and children above 6 years) and 500 mg granules for oral solution sachets (for infants and children below 6 years). Sabril™ is not adapted for administration to infants when a fraction of the sachet is needed. Manual splitting of the sachet or lengthy and error-prone dilutions are often required. This study is a descriptive, non-randomized, open label multi-centric acceptability study in infants and children affected with infantile spasms. The primary objective is to describe the adherence to the new formulation. Secondary objectives include: - evaluation of the palatability and user-friendliness of the new treatment, - evaluation of the pharmacokinetic parameters of the new formulation, - PK parameters, - evaluation of the tolerance, - measurement of taurine plasma levels. This study will recruit up to 40 patients with infantile spasms and pharmacoresistant partial epilepsy aged 1 month to 6 years in 23 clinical sites in France.
The purpose of this study was to investigate the presence of neuroinflammation in children with infantile spasms using 11C-PK11195 positron emission tomography (PK PET) scan, and its response to ACTH treatment by repeating the PK PET scan after treatment.
Infantile spasms constitute a unique age specific epilepsy syndrome of infancy, characterized by epileptic spasms often accompanied by neurodevelopmental regression and an EEG finding of hypsarrhythmia. When all 3 components are present, the eponym "West syndrome" is commonly used. West syndrome is a catastrophic epileptic encephalopathy. It does not respond well to standard anti-epileptic drugs. Hormonal therapy is the mainstay in the treatment of infantile spasms. This includes adreno-cortico trophic hormone (ACTH) and oral steroids. Variable dose of prednisolone used in the treatment. Oral prednisolone used in usual dose (2mg/kg) has been shown to be less effective as compared to ACTH. High dose prednisolone (4mg/kg) has been used in the treatment of infantile spasms, which has been shown to be as effective as ACTH. Pyridoxine has been used as first line treatment in Japan, however there is paucity of data on the efficacy of combination of pyridoxine with hormonal therapy. There are no studies comparing add on pyridoxine with high prednisolone versus high dose prednisolone alone in the treatment of infantile spasms. Therefore the study has been planned to see whether the addition of pyridoxine with high dose prednisolone in the treatment of infantile spasms improves the efficacy in terms of spasm cessation.
Infantile spasms (IIS), a characteristic epilepsy syndrome of infancy with often catastrophic developmental consequences, is known in some patients to have many different genetic, metabolic and structural etiologies. However, for most patients IIS is the only presenting clinical feature and the specific cause is unknown. Only two FDA approved pharmacologic treatments for IIS exist, Adrenocorticotropic hormone (ACTH) and vigabatrin. While vigabatrin may be the treatment of choice for Tuberous Sclerosis as a cause for IS, ACTH is the treatment of choice for all others. Unfortunately, a substantial number of patients may still not respond to ACTH and there is no a priori way that suggests which patients may be responders. This has led to the following key questions: Can novel genetic analyses determine known genetic causes of IS with greater efficiency (more timely and cost-effective)? Can novel genetic analyses determine previously unknown disease modifying genes that predispose individuals to develop IS? Can novel genetic analyses elaborate genes and gene polymorphisms that favor ACTH responsiveness? Do these polymorphisms suggest strategies to improve ACTH responsiveness?
Infantile spasms comprise a difficult to treat type of epilepsy in young children. Hormonal treatment, i.e. Prednisolone and ACTH are considered the treatment of choice. There is no consensus on the dosage of Prednisolone required for the treatment of infantile spasms. Recent data has shown that a high dose (4 mg/kg/day) may be more efficacious than the usual dose (2 mg/kg/day). However, there are no randomized controlled trials comparing these doses. A higher steroid dose may also be associated with more side effects. Therefore, this study was planned to compare the efficacy and tolerability of the high dose versus the usual dose in children with infantile spasms, in a randomized open-label trial design
The purpose of this study is to create a patient registry to collect and analyze information on subjects treated with Sabril and the prescribers of Sabril.
Infantile spasms constitute a type of catastrophic epilepsy syndrome occuring in young children. The ketogenic diet has been shown to be very effective in these children. The modified Atkins diet is a less restrictive option than the ketogenic diet, which has been effective in preliminary studies on refractory epilepsy in children, adolescents and adults. Modified Atkins diet may be of special importance in infants, as proteins are not restricted, hence no problems with growth are expected. Hence this pilot study has been planned to evaluate the efficacy and tolerability of the modified Atkins diet in infantile spasms refractory to conventional treatment (ACTH, vigabatrin, and anti-epileptic drugs).
