Arm Intervention/treatment
Experimental: treatment
all participants will be in this arm and will receive study drug 'Cannabidiol-Rich whole Plant Extract (TIL-TC150) to assess dosing and tolerability according to study protocol.TIL-TC150 Oil is the study product The active ingredients in TIL-TC150 Oil are THC and CBD, present in a 1:50 ratio. These active ingredients are derived from Cannabis sativa L. strains produced by Tilray, and suspended in a grape seed oil. This suspension is administered at a dose of 2mg/kg/day CBD divided BID and titrated up to a maximal dose of 16mg/kg/day CBD (or maximal tolerated).
 Drug: TIL-TC150
The active ingredients in TIL-TC150 are tetrahydrocannabinol (THC) and Cannabidiol (CBD), isolated from the Cannabis sativa L. strains produced by Tilray, and formulated into an oral liquid drug product.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Establishment of tolerability of TIL-TC150 by measuring the number of participants with adverse events and / or abnormal laboratory values that are related to treatment [ Time Frame: 20-64 weeks ]

    During this study, the dose of TIL-TC150 will be titrated according to study protocol and participant tolerance. Tolerance will be assessed as documented in title, by evaluating for adverse events clinically and by parent report of adverse event every week during the first 20 weeks of the study, also by blood work at weeks 0, 4, and between 8-16 weeks.

    For those choose to continue the study drug after 20 week period of assessment, tolerance will be evaluated by assessing for adverse events at weeks 28, 40,52 and 64.


  2. Establishment of tolerability of TIL-TC150 by standardised side effects questionnaire -pediatric epilepsy side effects questionnaire (PESQ) [ Time Frame: 16-64 weeks ]
    During this study, tolerance will also be assessed by the standardised side effects questionnaire- PESQ in clinic at weeks 2,4,8,12 and 16. For those choosing to continue therapy will be reassessed by PESQ in clinic at week 28,40,52 and 64.


Secondary Outcome Measures :
  1. The impact of therapy on quality of life using the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire [ Time Frame: 16-52 weeks ]
    The QOLCE will be completed by parents at clinic at first visit or baseline(week 0), at maximal dose (8 weeks) and at 16 weeks for primary analysis. For those choosing to continue therapy will be reassessed at 28 weeks and 52 weeks. Parents will be provided with a research report detailing the assessment findings at study completion.

  2. The impact of therapy on everyday behaviours using the Vineland Adaptive Behavior Scales, Second Edition. [ Time Frame: 20-64 weeks ]
    Vineland Adaptive Behaviour Scale, Second Edition: is a standardized parent interview to complete either in person at the clinic or by telephone on week 0, prior to starting the TIL-TC150. The interview will also be completed again at the primary evaluation period anytime between weeks 16 and 20 and again for those choosing to continue the therapy will be reassessed during the longitudinal follow-up anytime between 52 and 64 weeks. This will be done by study team. Parents will be provided with a research report detailing the assessment findings at study completion.

  3. change in seizure frequency from baseline [ Time Frame: 20 weeks ]
