Abstract

This disclosure provides formulations of enzalutamide and their use for treating hyperproliferative disorders.

Claims (20)

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.
