wherein administration of a single dose of the oral extended release once-daily pharmaceutical composition to healthy adult subjects results in a mean AUC inf from about 220 ng·hours/mL to about 450 ng·hours/mL of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]-pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide, and
wherein administration of a single dose of the oral extended release once-daily pharmaceutical composition to healthy adult subjects under fasting conditions results in a mean C max from about 25 ng/mL to about 40 ng/mL of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]-pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxide.
2. The composition of claim 1 , wherein the administration under fasting conditions results in a mean AUC inf from about 220 ng·hours/mL to about 320 ng·hours/mL.
3. The composition of claim 1 , wherein the administration under fed conditions results in a mean AUC inf from about 240 ng·hours/mL to about 450 ng·hours/mL.
4. The composition of claim 1 , wherein the difference in the mean AUC inf under fed conditions versus fasting conditions is about 30% or less.
5. The composition of claim 1 , wherein the administration under fasting conditions results in a mean C max from about 25 ng/mL to about 30 ng/mL.
6. The composition of claim 1 , wherein the difference in the mean C max under fed conditions versus fasting conditions is about 30% or less.
7. The composition of claim 4 , wherein the administration under fasting conditions results in a mean C max from about 25 ng/mL to about 30 ng/mL.
8. The composition of claim 4 , wherein the difference in the mean C max under fed conditions versus fasting conditions is about 30% or less.
9. The composition of claim 1 , wherein the administration results in a mean T max from about 2.0 to about 4.0 hours of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]-pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide.
10. The composition of claim 9 , wherein the administration under fasting conditions results in a mean T max of about 3.0 hours.
11. An oral extended release once-daily pharmaceutical composition comprising (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide in an amount sufficient to deliver 15 mg, per unit dosage form, of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide free base equivalent, wherein the oral extended release once-daily pharmaceutical composition is bioequivalent to an oral extended release once-daily film-coated tablet consisting of:
