Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
1. To determine the antitumor activity of Mifepristone (RU-486) in patients with advanced or recurrent endometrioid adenocarcinoma or low grade endometrial stromal sarcoma (LGESS).
2. To evaluate the quantitative and qualitative toxicities of Mifepristone in this patient population.
3. To evaluate at a tissue level the effect of Mifepristone on estrogen and progesterone receptors post treatment and to evaluate other markers that may reflect effects of Mifepristone on cancer cell growth.
4. To evaluate the effect of the agent and dosing schedule on the patient's quality of life.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Before treatment starts, patients will have a complete checkup, blood tests, a CT scan, and a chest x-ray. Women able to have children must have a negative urine pregnancy test. Blood tests and a complete checkup will also be done within 3 days of starting each course of therapy and a month after treatment ends. Tumors will be measured by CT scans once every 2-3 months and at the end of treatment.
Patients in this study will take Mifepristone in the form of a pill by mouth every day. Each course of therapy is 4 weeks long. Patients will see their doctor for an exam and blood tests before they begin each 4 week course of therapy. The dose of Mifepristone may be lowered if the patient has side effects. Patients who have a complete response (there is no evidence of cancer by physical exam or x-ray) will continue taking Mifepristone for 2 years after this response is documented. Other patients will take Mifepristone for as long as it benefits them.
This is an investigational study. At least 12 and as many as 37 patients will take part in this study. Patients from MD Anderson Cancer Center and Gynecologic Oncology of Houston, P.A. will be enrolled.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Patients should have previously undergone radical surgery (minimum of total abdominal hysterectomy and bilateral salpingoophorectomy) definitive radiation therapy, or not be candidates for such procedures.
3. The primary (including archived specimens) or recurrent tumor must be PR positive. Hormone receptor positivity is defined as PR positivity in \>/+10% cells by immunohistochemistry.
4. Prior radiotherapy must have been completed at least 2 weeks prior to the initiation of Mifepristone and patients must have recovered from the acute side effects of such treatment.
5. Performance status \< Zubrod 2.
6. Estimated life expectancy of at least 12 weeks.
7. Prior chemotherapy for recurrent or metastatic endometrial cancer is permitted.
8. Patients must have measurable disease as defined by the presence of bidimensionally measurable lesions with clearly defined margins on x-ray, scan (CT or MRI) or physical exam.
9. Adequate bone marrow reserve: granulocyte count \> 1.5 x 109/L, hemoglobin \> 9 g/dL (transfusion-independent) and platelets \> 100,000 K/UL.
10. Adequate liver and renal function as defined as: total bilirubin value \< 1.5 mg/dL; SGPT \< 2x the upper limit of normal or \< 5x the upper limit of normal when liver metastases are present; serum creatinine value of \< 1.8 mg/dL. All qualifying laboratory parameters must be determined within one week of first treatment.
11. Patient compliance and geographic proximity that allows adequate follow-up.
12. Signed informed consent.
Exclusion Criteria
2. Patients whose tumor is known to be PR negative.
3. Uncontrolled hypercalcemia.
4. Patients taking phenytoin, phenobarbital or carbamazepine.
5. Known predisposition to thromboembolic disorder, which in the investigator's judgment would put the patient at unacceptable risk for thromboembolic complications.
6. Patients who have received treatment for brain metastases may be enrolled provided they have remained stable for at least 6 months after surgery or radiation.
7. Women taking estrogen, progestin or antiprogestins. Patients taking these drugs must have discontinued their use at least 3 weeks prior to beginning treatment with Mifepristone.
8. History of other malignancy (except adequately treated non-melanomatous carcinoma of the skin or cervical carcinoma in situ) unless in complete remission and off all therapy for that disease for a minimum of 5 years.
9. Use of any chemotherapy or investigational agent within 3 weeks prior to taking study drug.
10. Concurrent serious infection.
11. Patients with serious intercurrent medical illness.
12. Serious concomitant systemic disorders incompatible with the study (at the discretion of the investigator).
13. Patients whom absorption of drugs is likely to be impaired due to either concomitant medications or prior surgery.
14. Overt psychosis or mental disability or otherwise incompetent to give informed consent.
