Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
  • Phase 3

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 116 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients must have a histologically documented primary, recurrent or residual meningioma which is unresectable.

  2. Patients must have active meningioma, which is defined to be one of the following:

    1. Progressive disease within the past 2 years.
    2. Recurrent Disease, as defined by the reappearance of a previously completely resected meningioma, within the past two years.
    3. New disease, defined as a diagnosis of meningioma within the previous two years
  3. Patients must have measurable or evaluable disease which is documented on CT or MRI scan.
  4. Patients should have already received radiotherapy unless radiotherapy is inappropriate due to tumor location(s) or unless radiotherapy, after discussion with the patient's physician, has been refused. If patients have received prior radiotherapy, this treatment must have been completed more than one year prior to study entry with documented progressive disease since completion of radiotherapy.
  5. Patients must be 18 years or older, and must have a performance status 0-2 by Southwest Oncology Group criteria.
  6. Patients must not have received prior cytotoxic chemotherapy for meningioma.
  7. Patients must have serum creatinine, SGOT, and bilirubin ≤ 2 x IULN.
  8. Patients requiring simultaneous administration of corticosteroids for cerebral edema must have been receiving a stable dose of corticosteroids for at least 4 weeks prior to study entry.
  9. Patients receiving anti-epileptic medications are eligible. However barbiturates should be avoided if possible.
  10. Patients with meningiomatosis (diffuse meningeal infiltration resulting in only nonevaluable meningeal thickening) are not eligible. However, patients with multiple measurable or evaluable meningioma tumor masses are eligible.
  11. Patients with malignant meningioma are not eligible. Malignant meningioma is defined as meningioma that demonstrates hypercellularity, loss of architecture, nuclear pleomorphism, numerous mitoses, focal necrosis, and brain invasion.
  12. Patients who have had additive or ablative modulation of sex hormone or glucocorticoid pathways within the preceding 3 months (not including stable corticosteroid therapy for cerebral edema) are not eligible. Such modulations include but are not limited to birth control pills, bilateral oophorectomy or orchiectomy, progestational inserts, oral or vaginal exogenous estrogens, androgens or antiandrogens, progestational agonists, tamoxifen, aminoglutethimide, o,p-DDD, ACTH, glucocorticoids not for cerebral edema, and leuprolides (or other LH-RH inhibitors). Patients must not have received prior mifepristone therapy for meningioma.
  13. Patients must not have serious intercurrent medical illness; that is, any illness that in the opinion of the investigator would prevent following the study regimen.
  14. Patients with clinical adrenal insufficiency requiring exogenous corticosteroid replacement are not eligible.
  15. Patients with a known allergy to mifepristone are not eligible.
  16. Patients with base of brain, cavernous sinus or optic nerve meningiomas or with visual symptoms must have a formal visual field examination.
  17. Pregnant or lactating women may not participate. Pre-menopausal women and men of reproductive potential may not participate unless they have agreed to use an effective local contraceptive method (such as a condom, diaphragm, or IUD) or abstinence during and for 3 months after study therapy.

  18. Patients with other prior or concurrent malignancy within the preceding 5 years, except surgically treated squamous or basal cell skin cancer or cervical cancer in situ, are not eligible.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to Treatment Failure
Time Frame: 6 years

From date of registration to first date of documentation of one of the following:

  1. Progression (clear worsening of evaluable disease must be confirmed by 2 investigators).
  2. Significant deterioration of at least one neurologic symptom
  3. Discontinuation of treatment for any reason.
  4. Death from any cause.
6 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of Treatment-Emergent Adverse Events
Time Frame: two years after beginning treatment
Patients will be followed for adverse events as defined by the SWOG toxicity criteria
two years after beginning treatment

The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
