Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Full-spectrum medicinal cannabis plant extract with 0.08% THC (FEN164).

FEN164 is an oil that will be administered orally over the course of the study.

The study involves the following phases:

• Baseline/Up-titration phase: Children will receive a baseline dose of 5mg/kg/day of FEN164 that will be increased weekly by 5mg/kg for a period of 4 weeks until the maximum tolerated dose or 20mg/kg is achieved.
• Treatment phase: Children will receive the maximum tolerated dose daily or 20mg/kg/day for either an 8-week period or they may choose to extend this up to 53 weeks (Extension phase).
• Down-titration phase: At the end of the Treatment Phase, children will receive a dosage that will be gradually decreased by 5mg/kg/week for a period of 4 weeks until the end of the study.
• Extension phase: Participants who choose to continue receiving the maximum tolerated dose beyond the set 8 weeks may do so for up to 53 weeks. They will undergo the Down-titration phase at the end of their Extension phase.
