|Condition or disease||Intervention/treatment||Phase|
|Uterine Fibroids||Drug: Proellex 12 mg Drug: Proellex 24 mg||Phase 2|
This is an open label, extension study of ZPV-200 applicable to multiple study sites. Subjects will chose to administer 12 mg Proellex vaginal doses once or twice daily (morning and evening). Total study participation for ZPV-200 EXT may be up to 120 days of drug treatment separated from ZPV-200 by an off-drug interval and a 30 day follow up visit.
Subjects already enrolled in ZPV-200EXT and the remainder of the subjects who enroll will have the option of administering 12 mg vaginal capsules once or twice daily. This choice will be provided to new subjects at Visit 1.
The first 4 subjects who chose to administer 12 mg Proellex twice daily, will have additional study procedures during the baseline visit and the day after.
Once a subject has selected a dosing regimen the subject must remain on that dose for the remainder of the study.
All subjects entering the ZPV-200EXT study will have completed the ZPV-200 study and will complete an off-drug interval prior to the start of their first dosing cycle. In the off-drug interval, subject must have a menses prior to resumption of the dosing cycle in the luteal phase.
Efficacy measurements will consist of UFS-QOL (uterine fibroid symptom quality of life survey) sub-scores and total score, and number of bleeding days per drug treatment cycle as recorded in subject diaries. Fibroid size will be assessed by MRI (magnetic resonance imaging) at the end of treatment (Visit 5), and changes in size of uterine fibroids will be compared to MRI results from Visit 2 and Visit 10 of ZPV-200.
Safety measurements for this study will include adverse events (AEs), clinical laboratory tests, hormone tests, physical examinations (including breast examination and pelvic examination with PAP smear) and vital signs.
