CONVULSIVE SEIZURE REDUCTION

EPIDIOLEX®
(cannabidiol)
significantly reduced convulsive seizures in patients living with Dravet syndrome

Results from the 14-week treatment period. Convulsive seizures included all countable atonic, tonic, clonic, and tonic-clonic seizures.

Patients at baseline1:

  • Had previously tried a median of 4 prior ASMs
  • Currently uncontrolled with a median of 3 current ASMs

In Study 3, 93% of patients were taking ≥2 ASMs at baseline and still experiencing a median of 13 convulsive seizures per 28 days.1

The most commonly used concomitant ASMs were:

65% clobazam |

57% valproate |

43% stiripentol

Seizure frequency reduction was reported as early as Day 10 in a post hoc analysis of the Dravet syndrome clinical trial.2

Recommended daily dosage is 10 mg/kg/day (5 mg/kg twice daily), with a maximum maintenance dosage of 20 mg/kg/day (10 mg/kg twice daily).

Administration of the 20 mg/kg/day dosage resulted in somewhat greater reductions in seizure rates than the recommended maintenance dosage of 10 mg/kg/day, but with an increase in adverse reactions. Patients with moderate to severe hepatic impairment require a dose adjustment.

RESPONDER RATES

EPIDIOLEX®
(cannabidiol)
cut seizure frequency by ≥50% and ≥75% in more patients than placebo in the Dravet syndrome trial

Responder rates (≥50% and ≥75% reductions in convulsive seizures from baseline)1

Results from the 14-week treatment period.

More patients achieved freedom from convulsive seizures with EPIDIOLEX than with placebo.

Decreasing n-values reflect a combination of discontinuations and rolling entry into the open-label extension trial.3

  • Retention rates at 1, 2, and 3 years were 72%, 53%, and 45%, respectively3
  • 8% (n=25) of withdrawals were due to adverse reactions3
  • LOCF sensitivity analyses were carried out on change in seizure frequency data to assess the effects due to withdrawal of patients3
95% (n=315) of patients with Dravet syndrome who completed controlled trials elected to continue into the open-label extension.3

Adverse events:

  • The long-term safety profile of EPIDIOLEX®
    (cannabidiol)
    in this open-label extension trial was generally similar to that observed in the EPIDIOLEX clinical development program3
  • Five deaths were reported in patients with Dravet syndrome, all of which were deemed unrelated to treatment by the investigator3
  • In the open-label extension trial, titration to doses over 20 mg/kg/day was permitted. At higher doses, an increase in adverse reactions was observed3
