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. The data described below reflect exposure of 80 patients with type 1 Gaucher disease in two open-label, uncontrolled, monotherapy trials, one open-label, active-controlled trial, and two extensions, who received miglustat capsules at doses ranging from 50 mg to 200 mg three times daily. Patients were aged 18 to 69 years at first treatment. The population was evenly distributed by gender. The most common serious adverse reaction reported with miglustat capsules treatment in clinical trials was peripheral neuropathy. The most commonly reported adverse reactions in patients treated with miglustat capsules (occurring in ≥ to 5%) that were considered related to miglustat capsules are shown in Tables 1 and 2.. The most common adverse reactions requiring intervention were diarrhea and tremor.. In two open-label, uncontrolled monotherapy trials, adult type 1 Gaucher disease patients were treated with miglustat capsules at a starting dose of 100 mg three times daily (dose range 100 to 200 mg three times daily) for up to 12 months in 28 patients [Study 1], or at a dose of 50 mg three times daily for up to 6 months in 18 patients [Study 2]. Table 1 below lists adverse reactions that occurred during the trials in ≥ to 5% of patients.

Table 2 lists adverse reactions that occurred during the trial in greater than or equal to 5% of patients.
