Active clinical trials for "Spasms, Infantile"

The purpose of the study is to evaluate the safety and tolerability, the pharmacokinetics and the efficacy of radiprodil in abolishing clinical spasms in subjects with drug-resistant infantile spasms

The primary purpose of this study was to evaluate the efficacy, safety, and tolerability of Cannabidiol Oral Solution (CBD) as adjunctive therapy with vigabatrin as initial therapy, compared to vigabatrin alone in the treatment of infants newly diagnosed with Infantile Spasms (IS).

Infantile Spasms (IS) is a diagnosis described as a fairly rare and terrible form of epilepsy that usually strikes children in the first year of life. There is a great need for safe and effective therapies in the treatment of IS. This need is even more important for infants and toddlers still sick after being treated with medicine that is already available. This is a multi-center study to evaluate the efficacy and safety of Cannabidiol Oral Solution (CBD) in the treatment of children aged 6 months through 36 months with a diagnosis of infantile spasms who have not responded to first line therapies. The overall study duration is expected to be 64 weeks for those subjects who respond to CBD treatment. The maximum possible study duration for each patient is approximately 64 weeks, however a subject will be deemed to have completed the study after 58 weeks.

To allow open-label extension to patients who have completed Protocol 1042-0500

OBJECTIVES: I. Evaluate the efficacy of surgical resection of an identifiable zone of cortical abnormality versus multiple drug therapy in children with infantile spasms refractory to standard therapy. II. Assess how infantile spasms interfere with development and whether this is partially reversible. III. Determine the predictors of good surgical outcome and whether surgery permanently controls seizures and improves development.

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.

This trial consists of 3 parts: a pilot safety phase, a pivotal randomized controlled phase, and an open-label extension phase. The open-label extension phase only will be described in this record. All participants will receive GWP42003-P.

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.

This trial consists of 3 parts: a pilot safety phase, a pivotal randomized controlled phase, and an open-label extension phase. The pilot phase only will be described in this record. 2 cohorts of 5 participants will be enrolled sequentially. All participants will receive GWP42003-P.

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).
