E.2 Objective of the trial

E.2.1

Main objective of the trial

Blinded Phase:
To evaluate the efficacy of GWP42003-P as add-on therapy in
reducing the frequency of seizures when compared with placebo
in patients with TSC.
Open-label Extension:
To evaluate via the adverse events (AE) profile the long term
safety and tolerability of GWP42003-P as add-on therapy in
children and adults with TSC who experience
inadequately-controlled seizures.

E.2.2

Blinded Phase:
• To evaluate the effect of GWP42003-P compared with
placebo on antiepileptic measures.
• To evaluate the safety and tolerability of GWP42003-P compared with placebo.

Open-label Extension:
• To evaluate the long term effects of GWP42003-P, as add-on therapy, on antiepileptic measures.
• To evaluate the long term safety and tolerability of GWP42003-P.

• Patient is currently using or has in the past used recreational or medicinal cannabis, or cannabinoid-based medications, within the three months prior to screening and is unwilling to abstain for the duration for the study.
• Patient has tumor growth which, in the opinion of the Investigator, could affect the primary
endpoint.
• Patient is female and of child bearing potential, or is male whose partner is of child bearing potential, unless willing to ensure that they or their partner use a highly effective method of birth control (e.g., hormonal contraceptives, intrauterine devices/hormone-releasing systems,
bilateral tubal occlusion, vasectomized partner, sexual abstinence) during the study and for three months thereafter.
• Female patient who is pregnant (positive pregnancy test), lactating or planning pregnancy during the course of the study and for three months thereafter.

E.5 End points

E.5.1

Primary end point(s)

Blinded Phase:
The primary endpoint is the change in number of TSC-associated seizures during the treatment period (maintenance and titration) compared to baseline in patients taking GWP42003-P compared with placebo.

Open-label Extension:
The safety of GWP42003-P will be evaluated by assessing the incidence, type and severity of AEs.

E.5.1.1

Timepoint(s) of evaluation of this end point

Baseline (Visit 2 to Visit 3) and the last 28 days of the evaluable period.

E.5.2

Secondary end point(s)

The following endpoints will be compared between treatment groups over the 16-week, double-blind
treatment period (all changes relative to baseline):
• Number of patients considered treatment responders defined as those with a ≥ 50% reduction in TSC-associated seizure frequency.
• Change in Caregiver Global Impression of Change (CGIC) or Subject Global Impression of Change (SGIC) score.
• Change in total seizures.
Other:
Antiepileptic efficacy measures
Growth and development (in patients under 18)
Quality of life
Safety and Tolerability

Open-label Extension
Will include secondary endpoints as in the core study, with the addition of percentage change in the TSC associated seizures and with removal of PK analysis.

E.5.2.1

Timepoint(s) of evaluation of this end point

Blinded phase (seizures) - Baseline (Visit 2 to Visit 3) and the last 28 days of the evaluable period.
Blinded phase (other efficacy) - Visits 3, 4, 5, 6, 7, 8 , 9 and 10.
Blinded phase (safety) - Visits 3, 4, 5, 6, 7, 8, 9 and 10.
OLE - ALL visit beginning at B1.
