             clinical history.

          -  Documented computerized tomography / magnetic resonance imaging that shows no
             progressive neurologic abnormality.

          -  Has focal seizures despite prior treatment with at least two AEDs (whether as

             stable regimen throughout the study.

          -  Subject is willing to keep any factors expected to affect seizures stable (such as the
             level of alcohol consumption and smoking).

        The patient may not enter Part B of the study if ANY of the following apply:

          -  Time of onset of focal epilepsy treatment is less than two years prior to enrolment.

          -  Patient has seizures that are not of focal onset.

          -  Patient only has focal seizures without impairment of consciousness or awareness and
             without an observable motor component (even if autonomic component is present).

          -  Episode(s) of status epilepticus during one year prior to screening.

          -  History of pseudo-seizures.

          -  Vagus Nerve Stimulation, Deep Brain Stimulation, Responsive Neurostimulator System or
             other epilepsy neurostimulation device have been implanted or activated less than one
             year prior to screening, and/or stimulation parameters have been stable for less than
             one month, and/or battery life of unit not anticipated to extend for duration of
             trial.

          -  Had epilepsy surgery within one year of screening.

          -  Subject has clinically significant unstable medical conditions other than epilepsy.

          -  Subject has an illness in the four weeks prior to screening or randomization, other
             than epilepsy, which in the opinion of the investigator would affect seizure
             frequency.

          -  Subject has significantly impaired hepatic function at Visit 1.

          -  Active suicidal plan/intent in the past six months, or a history of suicide attempt in
             the last two years, or more than one lifetime suicide attempt .

          -  Subject is currently using or has in the past used recreational or medicinal cannabis,

             excipients of the IMP(s).

          -  Subjects who have received an IMP within the 12 weeks prior to the screening visit.
