The present disclosure relates to processes for preparing (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, solid state forms thereof, and corresponding pharmaceutical compositions, methods of treatment (including treatment of rheumatoid arthritis), kits, methods of synthesis, and products-by-process.
1. An oral extended-release tablet comprising:
15 mg 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 at least one pharmaceutically acceptable excipient,
wherein:
a single administration of the tablet 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
a single administration of the tablet to healthy adult subjects 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 tablet 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 tablet 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 tablet of claim 1 , wherein the difference in the mean AUC inf under fed conditions versus fasting conditions is about 30% or less.
5. The tablet of claim 1 , wherein the difference in the mean C max under fed conditions versus fasting conditions is about 30% or less.
6. The tablet of claim 1 , wherein the difference in the mean C max under fed conditions versus fasting conditions is about 30% or less.
7. The tablet of claim 1 , wherein the administration results in a median 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.
8. The tablet of claim 7 , wherein the administration under fasting conditions results in a median T max of about 3.0 hours.
