6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In controlled and uncontrolled trials in patients with LGS and DS, 689 patients were treated with EPIDIOLEX, including 533 patients treated for more than 6 months, and 391 patients treated for more than 1 year.
In controlled and uncontrolled trials in patients with TSC, 223 patients were treated with EPIDIOLEX, including 151 patients treated for more than 6 months, 88 patients treated for more than 1 year, and 15 patients treated for more than 2 years.
In an expanded access program and other compassionate use programs, 271 patients with DS, LGS, or TSC were treated with EPIDIOLEX, including 237 patients treated for more than 6 months, 204 patients treated for more than 1 year, and 140 patients treated for more than 2 years.
Patients with LGS or DS In placebo-controlled trials of patients with LGS or DS (includes Studies 1, 2, 3, and a Phase 2 controlled study in DS), 323 patients received EPIDIOLEX [see Clinical Studies ( 14.1 , 14.2 )] .
Adverse reactions are presented below; the duration of treatment in these trials was up to 14 weeks.
Approximately 46% of patients were female, 83% were Caucasian, and the mean age was 14 years (range 2 to 48 years).
All patients were taking other AEDs.
In controlled trials in LGS or DS, the rate of discontinuation as a result of any adverse reaction was 2.7% for patients taking EPIDIOLEX 10 mg/kg/day, 11.8% for patients taking EPIDIOLEX 20 mg/kg/day, and 1.3% for patients on placebo.
The most frequent cause of discontinuations was transaminase elevation.
Discontinuation for transaminase elevation occurred at an incidence of 1.3% in patients taking EPIDIOLEX 10 mg/kg/day, 5.9% in patients taking EPIDIOLEX 20 mg/kg/day, and 0.4% in patients on placebo.
Somnolence, sedation, and lethargy led to discontinuation in 3% of patients taking EPIDIOLEX 20 mg/kg/day compared to 0% of patients taking EPIDIOLEX 10 mg/kg/day or on placebo.
The most common adverse reactions that occurred in EPIDIOLEX-treated patients with LGS or DS (incidence at least 10% and greater than placebo) were somnolence; decreased appetite; diarrhea; transaminase elevations; fatigue, malaise, and asthenia; rash; insomnia, sleep disorder, and poor quality sleep; and infections.
Table 3 lists the adverse reactions that were reported in at least 3% of EPIDIOLEX-treated patients, and at a rate greater than those on placebo, in the placebo-controlled trials in LGS and DS.

Patients with TSC In a placebo-controlled trial of patients with TSC (Study 4), 148 patients received EPIDIOLEX [see Clinical Studies ( 14.3 )] .
Adverse reactions are presented below; the duration of treatment in this trial was up to 16 weeks.
Approximately 42% of patients were female, 90% were Caucasian, and the mean age was 14 years (range 1 to 57 years).
All patients but one (25 mg/kg/day group) were taking other AEDs.
In the controlled trial in TSC, the rate of discontinuation as a result of any adverse reaction was 11% for patients taking EPIDIOLEX 25 mg/kg/day and 3% for patients on placebo.
The most frequent cause of discontinuation was rash (5%).
The most common adverse reactions that occurred in EPIDIOLEX-treated patients with TSC (incidence at least 10% at the recommended dosage and greater than placebo) were diarrhea; transaminase elevations; decreased appetite; somnolence; pyrexia; and vomiting.
Table 4 lists the adverse reactions that were reported in at least 3% of EPIDIOLEX-treated patients, and at a rate greater than those on placebo, in the placebo-controlled trial in TSC.

Additional Adverse Reactions in Patients with LGS, DS, or TSC Decreased Weight EPIDIOLEX can cause weight loss.
In the controlled trials of patients with LGS or DS (10 and 20 mg/kg/day), based on measured weights, 16% of EPIDIOLEX-treated patients had a decrease in weight of at least 5% from their baseline weight, compared to 8% of patients on placebo.
The decrease in weight appeared to be dose-related, with 18% of patients on EPIDIOLEX 20 mg/kg/day experiencing a decrease in weight at least 5%, compared to 9% in patients on EPIDIOLEX 10 mg/kg/day.
In the controlled trial of patients with TSC (25 mg/kg/day), 31% of EPIDIOLEX-treated patients had a decrease in weight of at least 5% from their baseline weight, compared to 8% of patients on placebo.
In some cases, the decreased weight was reported as an adverse event (see Tables 3 and 4).
Hematologic Abnormalities EPIDIOLEX can cause decreases in hemoglobin and hematocrit.
In controlled trials of patients with LGS or DS, the mean decrease in hemoglobin from baseline to end of treatment was -0.42 g/dL in EPIDIOLEX-treated patients receiving 10 or 20 mg/kg/day and -0.03 g/dL in patients on placebo.
A corresponding decrease in hematocrit was also observed, with a mean change of -1.5% in EPIDIOLEX-treated patients, and -0.4% in patients on placebo.
In the trial of patients with TSC, the mean decrease in hemoglobin from baseline to end of treatment was -0.37 g/dL in EPIDIOLEX-treated patients receiving 25 mg/kg/day and 0.07 g/dL in patients on placebo.
A corresponding decrease in hematocrit was also observed, with a mean change of -1.2% in EPIDIOLEX-treated patients, and -0.2% in patients on placebo.
There was no effect on red blood cell indices.
Thirty percent (30%) of EPIDIOLEX-treated patients with LGS and DS and 38% of EPIDIOLEX-treated patients with TSC developed a new laboratory-defined anemia during the course of the study (defined as a normal hemoglobin concentration at baseline, with a reported value less than the lower limit of normal at a subsequent time point), versus 13% of patients with LGS and DS on placebo and 15% of patients with TSC on placebo.
Increases in Creatinine EPIDIOLEX can cause elevations in serum creatinine.
The mechanism has not yet been determined.
In controlled studies in healthy adults and in patients with LGS, DS, and TSC, an increase in serum creatinine of approximately 10% was observed within 2 weeks of starting EPIDIOLEX.
The increase was reversible in healthy adults.
Reversibility was not assessed in studies in LGS, DS, or TSC.
Increases in Pneumonia with Concomitant Clobazam Pneumonia has been observed in controlled trials in patients with LGS and DS more frequently with clobazam (7 of 41 [17%] in patients receiving 10 mg/kg/day EPIDIOLEX, 13 of 125 [10%] in patients receiving 20 mg/kg/day EPIDIOLEX, and 1 of 123 [1%] receiving placebo) than without concomitant clobazam (0% in patients receiving 10 mg/kg/day EPIDIOLEX, 4 of 113 [4%] in patients receiving 20 mg/kg/day EPIDIOLEX, and 1 of 104 [1%] receiving placebo).
In the controlled trial in patients with TSC, pneumonia was observed more frequently with concomitant clobazam (3 of 18 [17%] in patients receiving 25 mg/kg/day EPIDIOLEX and 0 of 25 [0%] receiving placebo) than without clobazam (0 of 57 [0%] in patients receiving 25 mg/kg/day EPIDIOLEX and 1 of 51 [2%] receiving placebo).
( 6.1 ) The most common adverse reactions (10% or more for EPIDIOLEX and greater than placebo) in patients with tuberous sclerosis complex are: diarrhea; transaminase elevations; decreased appetite; somnolence; pyrexia; and vomiting.
