Application Number:	US17/985,220
Patent Claims:	1. A method of treating prostate cancer comprising: orally administering to a male human in need thereof two tablets, wherein each of the two tablets comprises: (a) a spray-dried dispersion consisting essentially of 80 mg amorphous enzalutamide and 400 mg hydroxypropyl methylcellulose acetate succinate; and (b) one or more inactive excipients; wherein the two tablets, when orally dosed to a cohort of male humans each receiving a 160 mg dose of enzalutamide, results in an area under the concentration-time curve that is equivalent to the area under the concentration-time curve that results from orally dosing four capsules to a cohort of male humans, wherein each of the four capsules comprises 40 mg enzalutamide dissolved in 904.96 mg caprylocaproyl polyoxylglycerides. 2. A method of treating prostate cancer comprising: orally administering to a male human in need thereof two tablets, wherein each of the two tablets comprises: (a) a spray-dried dispersion consisting essentially of 80 mg amorphous enzalutamide and 400 mg hydroxypropyl methylcellulose acetate succinate; and (b) one or more inactive excipients; wherein the two tablets, when orally dosed to a cohort of male humans each receiving a single 160 mg dose of enzalutamide, result in an area under the concentration-time curve from the time of dosing to seven days after dosing that is greater than 150 μg·hr/ml. 3. A method of treating prostate cancer comprising: orally administering to a male human in need thereof two tablets, wherein each of the two tablets comprises: (a) a spray-dried dispersion consisting essentially of 80 mg amorphous enzalutamide and 400 mg hydroxypropyl methylcellulose acetate succinate; and (b) one or more inactive excipients; wherein the amorphous enzalutamide remains amorphous following storage of the spray-dried dispersion at 40° C. and 75% relative humidity for one month. 4. A method of treating prostate cancer comprising: orally administering to a male human in need thereof two tablets, wherein each of the two tablets comprises: (a) a spray-dried dispersion consisting essentially of 80 mg amorphous enzalutamide and 400 mg hydroxypropyl methylcellulose acetate succinate; and (b) one or more inactive excipients; wherein the spray-dried dispersion has a glass transition temperature greater than 50° C. following equilibration overnight at ambient temperature and 75% relative humidity.
