6 ADVERSE REACTIONS

Clinically significant adverse reactions that appear in other sections of the labeling include the following:

  • Risks from Concomitant Use with Opioids [see Warnings and Precautions (5.1)]
  • Abuse, Misuse, and Addiction [see Warnings and Precautions (5.2)]
  • Dependence and Withdrawal Reactions [see Warnings and Precautions ( 5.3)]
  • Potentiation of Sedation from Concomitant Use with Central Nervous System Depressants [see Warnings and Precautions (5.4)]
  • Somnolence or Sedation [see Warnings and Precautions (5.5)]
  • Serious Dermatological Reactions [see Contraindications (4), Warnings and Precautions (5.6)]
  • Suicidal Behavior and Ideation [see Warnings and Precautions (5.7)]

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.

During its development for the adjunctive treatment of seizures associated with LGS, clobazam was administered to 333 healthy volunteers and 300 patients with a current or prior diagnosis of LGS, including 197 patients treated for 12 months or more. The conditions and duration of exposure varied greatly and included single- and multiple-dose clinical pharmacology studies in healthy volunteers and two double-blind studies in patients with LGS (Study 1 and 2) [see Clinical Studies (14)]. Only Study 1 included a placebo group, allowing comparison of adverse reaction rates on clobazam at several doses to placebo.

Adverse Reactions Leading to Discontinuation in an LGS Placebo Controlled Clinical Trial (Study 1)

The adverse reactions associated with clobazam treatment discontinuation in ≥1% of patients in decreasing order of frequency included lethargy, somnolence, ataxia, aggression, fatigue, and insomnia.

Most Common Adverse Reactions in an LGS Placebo Controlled Clinical Trial (Study 1)

Table 3 lists the adverse reactions that occurred in ≥5% of clobazam-treated patients (at any dose), and at a rate greater than placebo-treated patients, in the randomized, double- blind, placebo-controlled, parallel group clinical study of adjunctive AED therapy for 15 weeks (Study 1).
