If a dose is missed, the next Zavesca capsule should be taken at the next scheduled time. While Zavesca appeared to increase the clearance of imiglucerase by 70%, these results are not conclusive because of the small number of subjects studied and because patients took variable doses of imiglucerase [see Drug Interactions (7)]. Decreased spermatogenesis was reversible following 6 weeks of drug withdrawal. The following serious adverse reactions are described below and elsewhere in the labeling: 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. https://www.accessdata.fda.gov/drugsatfda_docs/nda/2003/21-348_Zavesca.cfm, https://www.accessdata.fda.gov/drugsatfda_docs/appletter/2019/021348Orig1s015ltr.pdf, https://www.accessdata.fda.gov/drugsatfda_docs/label/2014/021348s010lbl.pdf

At Month 12, the results showed non-significant decreases in platelet counts from baseline in all the treatment groups (by original randomization). Maternal death and decreased body weight gain were observed in rabbits orally dosed with miglustat during organogenesis at doses with exposures less than the human therapeutic systemic exposure. are breastfeeding or plan to breastfeed. Diarrhea decreased over time with continued Zavesca treatment, and may respond to individualized diet modification (e.g., reduction of sucrose, lactose and other carbohydrate intake), to taking Zavesca between meals, and/or to anti-diarrheal medications, most commonly loperamide. Other reported clinical experience has not identified differences in responses between elderly and younger patients. Actelion announced that United States (US) Food and Drug Administration's (FDA) Endocrinologic and Metabolic Drugs Advisory Committee voted (10 yes to 3 no) in its final vote in question that the benefit/risk profile of Zavesca® (miglustat) supports its approval for the treatment of progressive neurological manifestations in adult patients and pediatric patients with Niemann-Pick type C (NP-C) disease. In pregnant rabbits given miglustat by oral gavage at doses of 15, 30, 45 mg/kg/day during gestation days 6-18 (organogenesis), maternal death and decreased body weight gain were observed at 15 mg/kg/day (systemic exposures less than the human therapeutic systemic exposure, based on body surface area comparisons). Jay Rosenthal also provided additional documentation that could be useful as well when appealing. In two open-label, uncontrolled monotherapy trials, adult type 1 Gaucher disease patients were treated with Zavesca 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]. Zavesca® (100 mg miglustat capsule) is indicated for the oral treatment of adult patients with mild to moderate type 1 Gaucher disease. are pregnant or plan to become pregnant. Zavesca may affect how other medicines work. A report of data from a non-controlled, open-label extension to this initial randomized trial. The decision was based on results from the clinical trial OGT 918-007 and two multicenter NP-C disease cohort studies as well as other clinical trials in related lysosomal storage disorders for the safety and tolerability evaluation. Medicines are sometimes prescribed for purposes other than those listed in a Patient Information leaflet. But Zavesca© is an FDA approved medication of Gaucher’s disease, another Lisosomal storage disease.

It is invariably progressive and most patients die within five to ten years of diagnosis; for the majority, the disease is fatal during childhood. Ataxia, diminished/absent pupillary, palpebral, or patellar reflexes were observed in a dog at ≥495 mg/kg/day (50 times the human therapeutic systemic exposure based on body surface area comparisons, mg/m2), in a 2-week oral gavage toxicity study using doses of 85, 165, 495, and 825 mg/kg/d. Decreased spermatogenesis was reversible in rats following 6 weeks of drug withdrawal [see Nonclinical Toxicology (13.1)]. 100 mg white opaque hard gelatin capsules with "OGT 918" printed in black on the cap and "100" printed in black on the body. Twenty-nine patients were enrolled in a 6-month extension to Study 3. Vacuolization can sometimes occur as an artifact of tissue processing. Tremor usually began within the first month of therapy and in many cases resolved between 1 to 3 months during treatment. If you would like more information, talk with your doctor. Zavesca is a glucosylceramide synthase inhibitor indicated as monotherapy for the treatment of adult patients with mild to moderate type 1 Gaucher disease for whom enzyme replacement therapy is not a therapeutic option (e.g. There were no significant changes in any treatment group for liver volume, spleen volume, or hemoglobin concentration (See Tables 7-10).

Histopathology findings in the absence of clinical signs in the central nervous system of the monkey (brain, spine) that included vascular mineralization, in addition to mineralization and necrosis of white matter were observed at >750 mg/kg/day (4 times the human therapeutic systemic exposure based on area-under-the-plasma-concentration curve [AUC] comparisons) in a 52-week oral toxicity study using doses of 750 and 2000 mg/kg/d. The pharmacokinetics of miglustat were not altered after repeated dosing three times daily for up to 12 months. Clinical studies of Zavesca did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently than younger patients. Patients were randomized 1:1:1 to one of three treatment groups, as follows: Patients were treated for 6 months, and 33 patients completed the study. It may be necessary to reduce the dose to one 100 mg capsule once or twice a day in some patients due to adverse reactions, such as tremor or diarrhea. Impairment of Fertility: Male rats, given 20 mg/kg/day miglustat by (systemic exposure less than the human therapeutic systemic exposure based on body surface area comparisons, mg/m2) oral gavage 14 days prior to mating, had decreased spermatogenesis with altered sperm morphology and motility and decreased fertility. Advise patients to adhere to dietary instructions.

In female rats given miglustat by oral gavage at doses of 20, 60, 180 mg/kg/day beginning 14 days before mating and continuing through gestation day 17 (organogenesis), decreased live births including complete litter loss and decreased fetal weight were observed in the mid-dose and high-dose groups (systemic exposures ≥2 times the human therapeutic systemic exposure, based on body surface area comparison). At Month 6, the results showed a decrease in mean percent change in liver volume in the Zavesca treatment group compared to the imiglucerase alone group. Part 2 (PDF)
The effective half-life of miglustat is approximately 6 to 7 hours, which predicts that steady-state will be achieved by 1.5 to 2 days following the start of three times daily dosing. Part 4 (PDF)
