A phase II evaluation of mifepristone in the treatment of recurrent or persistent epithelial ovarian, fallopian or primary peritoneal cancer: a gynecologic oncology group study.

OBJECTIVE

To evaluate the effectiveness and toxicity of mifepristone in patients with ovarian, peritoneal and fallopian tube cancers.

METHODS

Patients with confirmed epithelial ovarian, peritoneal and fallopian tube cancers which were persistent or recurred in less then 1 year after primary chemotherapy were entered into this study. Patients were given mifepristone 200 mg by mouth daily for a 28 day cycle. The medication was stopped for unacceptable toxicity or tumor progression.

RESULTS

Twenty-four patients were entered into the study. Twenty-two patients were evaluable for response. Only one patient had a partial response for a response rate of only 4.5% (90% confidence interval: 0.2%, 19.8%).

CONCLUSION

Mifepristone has not proven to be an effective agent in the treatment of patients with recurrent or persistent ovarian, peritoneal and fallopian tube cancers.
