After approval miglustat in EU (2004) Objectives To establish a set of recommendations for collecting safety, efficacy and QoL data (12 months and longer follow-up) To guarantee the safe and proper use of miglustat in everyday clinical use Treatment Followed the recommendations of the European Working Group on Gaucher Disease Advisory Council ZAGAL study.

ZAGAL study Changes in the atherogenic profile of patients with type 1 Gaucher disease after miglustat therapy. In 26 GD1 patients treated with miglustat for up to 36 months: Group A: 10 patients therapy-naïve significantly: plasma HDL-c and apoA-I, and slightly increased TC; TG, CRP concentrations, and TC/HDL-c ratios decreased significantly Group B: 16 patients switched from enzyme replacement therapy (ERT); No changes in HDL-c and apoA-I, or in the TC/HDL-c ratio. CRP was observed after 12 months. LDL-c and apoB were not significantly altered in either patient group Miglustat appears to have beneficial effects on plasma lipid, lipoprotein, and CRP concentrations in therapy-naïve GD1 patients, resulting in an improved atherogenic lipid profile.. Puzo J et al Atherosclerosis June 29th 2012

ZAGAL study In summary: 42 patients are on miglustat therapy and 15 patients have more than 7 years under therapy. The goals of therapy have been achieved. 3 patients died by non-related causes (2 neoplasia and 1 hearth attack), 1 patient have discontinued by planning to become pregnant 6 discontinuing by poor filling or intolerance. 8 patients had transitory diarrhea and flatulence.

ZAGAL study. Recommendations In order to avoid gastrointestinal disturbances during Miglustat therapy, we are recommending two strategies: To administrate therapy without meals for example 2 hours before breakfast, lunch and dinner To start therapy in scalating doses: during the first week only 100 mg /day during the second week only 200 mg/day during third week and later total therapy with 300 mg/day Simultaneously it is convennient consider the content of carbohidrates in the diet according the following suggestions: Giraldo P et al.
