Summary for Patent: 12,594,243

Title:	Pharmaceutical formulations
Abstract:	The pharmacokinetic profile of the SGLT2 inhibitor bexagliflozin can be improved by formulating it as an extended release tablet. Compared with standard immediate-release dosage forms these tablets can permit a lower peak plasma concentration, Cmax, while maintaining plasma concentrations at therapeutic levels for a desired period. This can be used, for instance, to administer lower doses while still providing the same pharmacological effect.

Patent Claims:	1. A tablet comprising: (a) 1-13% by weight of bexagliflozin; (b) 30-35% by weight of glyceryl dibehenate; (c) 16-20% by weight of polyethylene oxide having an average molecular weight of 900,000 g/mol; (d) 11-13% by weight of lactose; (e) 10-12% by weight of poloxamer 188; (f) 18-20% by weight of microcrystalline cellulose; (g) 1.0-1.5% by weight of colloidal silicon dioxide; and (h) 1.5-2.5% by weight of magnesium stearate, wherein the tablet provides a maximum bexagliflozin plasma concentration in a fasted human subject between 80-150 ng/mL. 2. A tablet comprising: (a) from 3 mg to 60 mg of bexagliflozin; (b) from 50 mg to 75 mg of polyethylene oxide having an average molecular weight of 900,000 g/mol; (c) from 100 mg to 140 mg of glyceryl dibehenate; (d) from 40 mg to 50 mg of lactose; (e) from 40 mg to 45 mg of poloxamer 188; (f) from 60 mg to 80 mg of microcrystalline cellulose; (g) from 4 mg to 5 mg of colloidal silicon dioxide; and (h) from 6 mg to 9 mg of magnesium stearate, wherein the tablet provides a maximum bexagliflozin plasma concentration in a fasted human subject between 80-150 ng/mL. 3. The tablet of claim 2, comprising (a) 20 mg of bexagliflozin; (b) 65 mg of polyethylene oxide having an average molecular weight of 900,000 g/mol; (c) 120 mg of glyceryl dibehenate powder; (d) 45 mg of spray-dried lactose monohydrate; (e) 42 mg of micronized poloxamer 188; (f) 70 mg of microcrystalline cellulose; (g) 4.5 mg of amorphous anhydrous colloidal silicon dioxide; and (h) 7.5 mg of magnesium stearate. 4. The tablet of claim 2 further comprising from 10 mg to 12 mg of a film coating comprising polyvinyl alcohol, titanium dioxide, and polyethylene glycol 3350. 5. The tablet of claim 3 further comprising a film coating consisting of 11.22 mg of a mixture of polyvinyl alcohol, titanium dioxide, polyethylene glycol 3350, talc, disodium 2-[[4-[ethyl-[(3-sulfonatophenyl)methyl]amino]phenyl]-[4-[ethyl-[3-sulfonatophenyl)methyl]azaniumylidene]cyclohexa-2,5-dien-1-ylidene]methyl]benzenesulfonate, and indigo carmine. 6. The tablet of claim 2, wherein the tablet releases 20-45% by weight of bexagliflozin after 3 hours, according to an in vitro dissolution test performed with a United States Pharmacopoeia Apparatus 1 at 50 rpm with 900 mL of 0.1 N HCl at 37±0.5° C. 7. The tablet of claim 2, wherein the tablet releases 45-75% by weight of bexagliflozin after 5 hours, according to an in vitro dissolution test performed with a United States Pharmacopoeia Apparatus 1 at 50 rpm with 900 mL of 0.1 N HCl at 37±0.5° C.
