Brief summary: This study is a double-blind crossover study in female healthy volunteers to compare the pharmacokinetics and safety of a single dose each of two different formulations of Proellex for oral administration. Each formulation will be designated as either Treatment A or Treatment B. A total of 12 subjects who meet the eligibility criteria will be randomized to receive either Treatment A or Treatment B as their first assigned treatment. After a 7-day washout period subjects will receive the alternative treatment. On the day of each treatment subjects will remain in the clinic overnight and undergo 72-hour pharmacokinetic assessment at the following time points: 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48 and 72 hours after administration of study drug.


Eligibility criteria: Inclusion Criteria:

3. History of menstrual events that occur in regular cycles
4. Agreement not to attempt to become pregnant
5. Agrees to use double-barrier contraception during the study and for 30 days after discontinuation of study medication. Acceptable double-barrier methods are: male condom with spermicide; male condom with diaphragm; diaphragm containing spermicide plus additional intra-vaginal spermicide;

7. Normal laboratory values or clinically insignificant findings at screening as determined by the Investigator;
8. Subject is willing to remain in the clinic overnight for PK assessment on Days 0 and 8
9. Ability to complete the study procedures in compliance with the protocol.
