ORAL ELIGLUSTAT TRANSMUCOSAL DELIVERY SYSTEM

The present disclosure relates to an oral eliglustat transmucosal delivery system. More specifically, the present disclosure is related to an oral transmucosal dosage form comprising a non-disintegrating solid mass comprising (a) a hydrophilic viscosity modifying agent selected from a natural or a synthetic gum with a molecular weight of 10,000 Daltons or greater, (b) a low molecular weight water soluble component with a molecular weight of less than 10,000 Daltons and (c) not more than 70 mg eliglustat, wherein the dosage form is 500 mg or less and provides an oral cavity residence time of at least about 5 minutes, and wherein the dosage form generates a microenvironment inside the oral cavity exhibiting a thixotropic behavior with viscosities of at least 50 poises at 1/sec shear rate and at least 10 poises at 10/sec share rate. The dosage forms of as described herein have at least 30% dose reduction as compared to commercially available eliglustat capsules. In addition, unlike the dosing prerequisite for commercially available eliglustat capsules, the oral eliglustat transmucosal dosage form described herein can be administered to patients with Gaucher disease type 1 without pre-determination of patients' CYP2D6 genotype.
