ONC201 and Radiation Therapy Before Surgery for the Treatment of Recurrent Glioblastoma

Study Overview
=================
Brief Summary
-----------------
This phase I trial studies the effects of ONC201 in combination with standard of care radiation therapy in treating patients with glioblastoma that has come back (recurrent). ONC201 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy photons to kill tumors cells and shrink tumors. Giving ONC201 in combination with radiation therapy may help treat patients with recurrent glioblastoma.

Detailed Description
-----------------
PRIMARY OBJECTIVES: I. To determine the safety and tolerability of Akt/ERK Inhibitor ONC201 (ONC201) in combination with radiotherapy before a tumor resection in recurrent glioblastoma (GBM) patients. II. To determine the ability of ONC201 to decrease glioblastoma-initiating cells as determined by percentage of neurosphere formation of treated brain tumor tissues compared to non-treated brain tumor tissues. SECONDARY OBJECTIVES: I. To determine the ability of ONC201 to decrease glioblastoma-initiating cells as determined by expression of glioma stem cells using ribonucleic acid-sequencing (RNA-Seq) of treated brain tumor tissues compared to non-treated brain tumor tissues. II. To assess the ability of ONC201 to inhibit Akt by evaluating progressive disease (PD) markers by immunohistochemistry such as Sox2, Oct3/4, Nanog, Akt and p-Akt, GSK3 and pGSK3alpha. EXPLORATORY OBJECTIVES: I. To estimate progression-free survival (PFS) and overall survival (OS). II. To determine the immunogenicity of the combination of ONC201 + radiation therapy (RT) via immune cell studies. III. To determine if the combination of ONC201 + RT leads to increase cholesterol synthesis. IV. To determine molecular markers of response to ONC201 in correlation to survival such as DRD5 expression. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients undergo radiation therapy for 10 fractions over 2 weeks, and receive ONC201 orally (PO) daily on days 1, 2, 8, and 9. Beginning 24 hours after completion of radiation therapy, patients undergo surgical resection. Beginning 7 days from last pre-surgery dose of ONC201, patients receive ONC201 PO daily on two consecutive days weekly (2 days on/5 days off) in the absence of disease progression or unacceptable toxicity. ARM II: Patients undergo radiation therapy for 10 fractions over 2 weeks. Beginning 24 hours after completion of radiation therapy, patients undergo surgical resection. After recovery from surgery, patients receive ONC201 PO daily on two consecutive days weekly (2 days on/5 days off) in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and then every 3 months.

Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum follicle stimulating hormone [FSH] levels > 40 mIU/mL and estradiol < 20 pg/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential Female participants of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and through 30 days after the last dose of study drug. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and through 30 days after the last dose of study drug. Women who are nursing should discontinue nursing prior to starting study drug Participants must have no concurrent malignancy except curatively treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix, breast, or bladder. Patients with prior malignancies must be disease-free for >= three years Participants must be able to swallow whole capsules Participants must have at least 20 (preferably 40) slides of archival tumor tissue from a prior surgery demonstrating GBM Participants must have the ability to understand and the willingness to sign a written informed consent document Exclusion Criteria: Participants receiving any other investigational agents or using an investigational device are ineligible Participants with a history of allergic reactions attributed to compounds of similar chemical or biologic composition to ONC201 are ineligible Participants may not have had prior treatment with ONC201 Participants may have had prior treatment with bevacizumab/VEGFR inhibitors, but last dose of treatment must be at least 4 weeks prior to the date of planned tumor resection Participants may not be on concurrent treatment with Optune device.

Patients on sertraline which has the conditional risk of prolonging the QT interval will be allowed on study if they hold sertraline on the day of ONC201 administration Participants using concomitant CYP3A4/5 inhibitors within 72 hours prior to starting study drug administration are ineligible Participants with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements, are ineligible Pregnant women are excluded from this study because there is unknown risk of ONC201 on the fetus. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother on ONC201, breastfeeding should be discontinued if the mother is treated with ONC201
