Natural Progesterone for the Treatment of Recurrent Glioblastoma

Stopped early · Early Phase 1

Conditions studied: Gliosarcoma, Recurrent Glioblastoma

In brief

This early phase I trial identifies the best dose, possible benefits and/or side effects of natural progesterone in treating patients with glioblastoma that has come back (recurrent). Progesterone is a type of hormone made by the body that plays a role in the menstrual cycle and pregnancy. Progesterone may help control tumor growth and spread in patients with glioblastoma.

• Patient must not have a known allergy to progesterone
• In females, no active vaginal bleeding
• Patients may not be enrolled on any other therapeutic trial for which they are receiving an anti-tumor therapy

You may not qualify if…

• Patients with pacemakers, aneurysm clips, neurostimulators, cochlear implants, metal in ocular structures, history of being a steel worker, or other incompatible implants which makes MRI safety an issue are excluded
• Patients that have any significant medical illnesses that in the investigator's opinion cannot be adequately controlled with appropriate therapy or would compromise the patient's ability to tolerate this therapy are excluded
• Patients with a history of severe hepatic dysfunction of disease are excluded
• Patients with a history of idiopathic jaundice, severe pruritus and pemphigoid gestationis during pregnancy are excluded
• Patients with a history of breast or genital tract cancer are excluded
• Patients with a history of any other invasive cancer (except non-melanoma skin cancer and excluding carcinoma in-situ), unless in complete remission and off all therapy for that disease for >= 3 years, are ineligible
• Patients with an active infection or serious intercurrent medical illness are ineligible
• Patients who received any other in anti-tumor agents (including investigational ones) must be off therapy for 4 weeks prior to initiating progesterone on study
• Patient receiving anti-coagulation therapy are excluded
• Patient with active or recent (within 6 months) thromboembolic disease are excluded
• Patient with current ongoing therapy with estrogen/progesterone (including hormonal contraceptives) are excluded. Would need to stop this form of birth control at least 7 days prior to initiation of therapy to be eligible
