A New Two-Part Clinical Trial Will Investigate Cannabidiol Oral Solution as an Add-On Therapy in Infants with Seizures Caused by Tuberous Sclerosis Complex

The study will be comprised of two parts:

  • Part A will evaluate the safety and pharmacokinetics of GWP42003-P compared with standard of care treatment for a period of 17 weeks in participants with TSC. This means half of the infants who take part in this study will be treated with GWP42003-P as well as their usual ongoing medicines, known as standard of care. The other half will be treated with their ongoing medicines only. Part A will last approximately 29 weeks total, which includes a 1- to 2-week screening period, a 4-week baseline period and a 17-week treatment period (including a 2- to 5- week titration period). Infants who complete Part A of the trial and continue to meet all eligibility criteria will be invited to continue in Part B. Parents/caregivers who do not wish their infants to continue in Part B will enter an up to 2-week taper period and a safety follow-up period (4 weeks after the end-of-taper visit).
  • Part B will evaluate the long-term safety and tolerability of GWP42003-P for 52 weeks. All Part B participants will receive GWP42003-P. The duration of Part B will be approximately 59 weeks total, including a 2- to 5-week titration period for those participants randomized to standard of care treatment only in Part A of the trial, a 2-week taper period and a safety follow-up period (4 weeks and end-of-taper visit).
