Conditions: Spasms, Infantile
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 9
Healthy volunteers: no

Brief summary:
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.

Detailed description:
A protocol amendment in May 2016 created two parts to this trial: Part A (the extended treatment period) and Part B (the safety treatment period), whose objectives are as follows:

Primary Part A: To evaluate the efficacy of Cannabidiol Oral Solution in treating refractory infantile spasms (IS).

Secondary:

Part A:

* To evaluate the safety of Cannabidiol Oral Solution in treating refractory infantile spasms.

Part B:

* To assess the long-term safety of Cannabidiol Oral Solution as an adjunctive treatment for subjects with Infantile Spasms (IS)
* To establish the continued efficacy of Cannabidiol Oral Solution in maintaining seizure control in subjects with IS
* To assess the global status of subjects taking Cannabidiol Oral Solution for an extended period of time determined by various qualitative assessments
* To monitor for changes in plasma levels of Cannabidiol Oral Solution during long-term treatment of subjects with IS

Arms:
arm 1: The dose of Cannabidiol Oral Solution will begin at 20 mg/kg/day \[10 mg/kg twice per day (BID)\], will be adjusted at any time if the investigator feels the safety or well-being of the participant is at risk, and will be titrated up or down according to protocol-stipulated parameters and at the investigator's discretion after Day 14 to enhance efficacy. Dose will not exceed 40 mg/kg/day.

Interventions: intervention 1: Cannabidiol Oral Solution
Intervention descriptions: intervention 1: 20 or 40 mg/kg/day BID
