Further study details as provided by Repros Therapeutics Inc.:

Primary Outcome Measures:
  • Proellex peak plasma concentration (Cmax) [ Time Frame: 24 hours ]
  • Proellex time to peak plasma concentration (tmax). [ Time Frame: 24 hours ]

Secondary Outcome Measures:
  • The area under the plasma concentration over time curve from zero to the last measurable Proellex plasma concentration (AUC0-24) was calculated. [ Time Frame: 24 hours ]
  • The area under the plasma concentration over time curve from zero to infinity (AUC 0-infinity). [ Time Frame: 24 hours ]
  • Terminal elimination half-life (t1/2). [ Time Frame: 24 hours ]
  • Vital signs evaluated at screening, treatment days 0 and 1. Clinical laboratory values obtained at screening, treatment days 0 and 1. Adverse events assessed at treatment visits and followed until resolution. [ Time Frame: 24 hours ]

Enrollment: 21
