Cohort 1: Eliglustat monotherapyEXPERIMENTALEliglustat for at least two years. Cohort 1 patients that experience significant clinical decline will receive rescue treatment. Rescue Treatment Step 1: Switch from eliglustat to imiglucerase monotherapy. Rescue Treatment Step 2: Patients who after 6 months of rescue therapy with imiglucerase monotherapy do not show improvement in the parameter(s) that led to the switch from eliglustat to imiglucerase, will then receive combination therapy with eliglustat + imiglucerase.
Cohort 2: Eliglustat plus imigluceraseEXPERIMENTALEliglustat plus imiglucerase for three years, at the dose of enzyme replacement therapy received before enrollment. After Week 52, Cohort 2 patients will switch to eliglustat monotherapy for the remainder of the study if the desired clinical response has been achieved.
