Claims

exact text as granted — not AI-modified
1 .- 114 . (canceled) 
     
     
         115 . A once daily pharmaceutical dosage form comprising:
 11 mg of tofacitinib, or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof, or 22 mg of tofacitinib, or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof,   wherein said dosage form is a sustained release dosage form, and when added to a test medium comprising 900 ml of 0.05M pH 6.8 potassium phosphate buffer at 37° C. in a standard USP rotating paddle apparatus and the paddles are rotated at 50 rpm, dissolves not more than 30% of the tofacitinib, or pharmaceutically acceptable salt thereof, in 1 hour, and not less than 35% and not more than 75% of the tofacitinib, or a pharmaceutically acceptable salt thereof, in 2.5 hours and not less than 75% of the tofacitinib, or pharmaceutically acceptable salt thereof, in 5 hours.   
     
     
         116 . A once daily pharmaceutical dosage form comprising:
 11 mg of tofacitinib, or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof,   wherein the dosage form is a sustained release dosage form and when administered orally to a subject provides an AUC in the range of 80% to 125% of the AUC of 5 mg of tofacitinib or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof administered as an immediate release formulation BID.   
     
     
         117 . The pharmaceutical dosage form of  claim 116 , wherein the AUC range is 90% to 110% and the geometric mean plasma of Cmax to Cmin from 20 to 40. 
     
     
         118 . The pharmaceutical dosage form of  claim 117 , wherein the geometric mean plasma Cmax to Cmin from 20 to 30. 
     
     
         119 . The pharmaceutical dosage form of  claim 118 , wherein when the dosage form is administered orally to the subject provides a geometric mean plasma Cmax in the range of 70% to 125% of the mean plasma Cmax of tofacitinib administered as the immediate release formulation BID at steady state. 
     
     
         120 . The pharmaceutical dosage form of  claim 116 , wherein when the dosage form is administered orally to the subject provides a drug holiday in the range of 80% to 110% of the drug holiday of tofacitinib administered as the immediate release formulation BID over a 24 hour period. 
     
     
         121 . The pharmaceutical dosage form of  claim 116 , having a drug holiday from 15 to 18 hours over the 24 hour period. 
     
     
         122 . A once daily pharmaceutical dosage form comprising
 11 mg of tofacitinib, or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof, or 22 mg of tofacitinib, or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof,   wherein said dosage form is a sustained release dosage form, and when administered to a subject has a mean area under the plasma concentration curve versus time following administration from 17 ng-hr/mL per mg of tofacitinib dosed to 42 ng-hr/mL per mg of tofacitinib dosed and a ratio of geometric mean plasma Cmax to Cmin from 10 to 100.   
     
     
         123 . The pharmaceutical dosage form of  claim 122 , wherein the ratio of geometric mean plasma Cmax to Cmin from 20 to 40. 
     
     
         124 . The pharmaceutical dosage form of  claim 123 , wherein the ratio of geometric mean plasma Cmax to Cmin from 20 to 30. 
     
     
         125 . The pharmaceutical dosage form of  claim 122 , wherein the subject has a single, continuous time above 17 ng/ml from 6 to 15 hours and a single, continuous time below 17 ng/ml from 9 to 18 hours over a dosing 24 hours interval. 
     
     
         126 . The pharmaceutical dosage form of  claim 125 , wherein the subject has a single, continuous time above 17 ng/ml from 6 to 9 hours. 
     
     
         127 . The pharmaceutical dosage form of  claim 125 , wherein the subject has a single, continuous time below 17 ng/ml from 15 to 18 hours. 
     
     
         128 . The pharmaceutical dosage form of  claim 122 , wherein the subject has a mean maximum plasma concentration (Cmax) from 3 ng/mL per mg to 6 ng/mL per mg of tofacitinib dosed. 
     
     
         129 . A once daily pharmaceutical dosage form comprising:
 22 mg of tofacitinib, or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof,   wherein the dosage form is a sustained release dosage form and when administered orally to a subject provides an AUC in the range of 80% to 125% of the AUC of 10 mg of tofacitinib or an equivalent amount of tofacitinib in the form of a pharmaceutically acceptable salt thereof administered as an immediate release formulation BID.   
     
     
         130 . The pharmaceutical dosage form of  claim 129 , wherein the AUC range is 90% to 110% and the geometric mean plasma of Cmax to Cmin from 20 to 40. 
     
     
         131 . The pharmaceutical dosage form of  claim 130 , wherein the geometric mean plasma Cmax to Cmin from 20 to 30.
