Everolimus in Treating Patients With Recurrent Low-Grade Glioma

• Status: Completed
• Trial end date: 2017-11-13
• Target enrollment: 0

Summary

This phase II trial studies how well everolimus works in treating patients with recurrent low-grade glioma. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Susan Chang; University of California, San Francisco
• Collaborator: Novartis
• Treatments: Everolimus; Sirolimus

• Platelets >= 100 x 10^9/L

• Hemoglobin (Hb) > 9 g/dL

• Serum bilirubin =< 1.5 x upper limit of normal (ULN)

• International normalized ratio (INR) < 1.5 (anticoagulation is allowed if target INR =< 1.5 on a stable dose of warfarin or on a stable dose of low molecular weight [LMW] heparin for > 2 weeks at the time of registration)

• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 x ULN

• Serum creatinine =< 1.5 x ULN

• Fasting serum cholesterol =< 300 mg/dL OR =< 7.75 mmol/L AND fasting triglycerides =< 2.5 x ULN; NOTE: In case one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication

• Patients must have histologically proven intracranial low-grade glioma at initial diagnosis; low-grade gliomas include: astrocytoma, oligodendroglioma and mixed oligoastrocytoma; pilocytic astrocytomas are excluded

• Patients must have unequivocal evidence for tumor recurrence or progression by histology as determined by review of pathology by an attending neuro-pathologist at UCSF

• If most recent histology shows progression to high grade glioma, patients must have had prior radiotherapy in order to be eligible

• Paraffin-embedded sections of tissue acquired from surgery at the time of suspected recurrence must be available for analysis

• Patients must have evidence for tumor recurrence or progression by MRI as determined by radiographic review of images by an attending neuro-oncologist or neuro-radiologist at UCSF

• If the steroid dose is increased between the date of the MRI and registration on the trial, a new baseline MRI is required; this MRI must be performed after >= 5 days on a stable dose of steroids

• An MRI must be used throughout the period of protocol treatment for tumor measurement

• Patients must have evaluable disease

• Patients may have had treatment (including radiotherapy) for any number of relapses prior to this recurrence

• Patients must be at least 4 weeks from the completion of any radiation therapy

• Patients must be less than 4 months from the surgical procedure for this recurrence

• Patients must have recovered from the toxic effects of prior therapy:

• 4 weeks from any investigational agent

• 4 weeks from prior cytotoxic therapy (except 6 weeks from nitrosoureas, 3 weeks from procarbazine, 3 weeks from vincristine)

• 3 weeks for non-cytotoxic or biologic agents e.g., interferon, tamoxifen, thalidomide, cis-retinoic acid, tarceva, etc; note a 3-week washout is required for prior treatment with bevacizumab

Exclusion Criteria:

• Patients who have not recovered from the side effects of a major surgery or significant traumatic injury or patients that may require major surgery during the course of the study

• Patients receiving chronic, systemic treatment with corticosteroids or another immunosuppressive agent; topical or inhaled corticosteroids, and treatment with low dose Decadron (=< 3 mg daily) are allowed

• Other than surgery, patients may not have therapy for this recurrence (including radiation); supportive care such as steroids or anti-epileptics does not constitute treatment of recurrence

• Patients must not 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

• Patients with a history of any other cancer (except for adequately treated carcinoma of the cervix or basal or squamous cell carcinomas of the skin), unless in complete remission and off of all therapy for that disease for a minimum of 3 years are ineligible

• Patients should not receive immunization with attenuated live vaccines within one week of study entry or during study period; close contact with those who have received attenuated live vaccines should be avoided during treatment with everolimus; examples of live vaccines include intranasal influenza, measles, mumps, rubella, oral polio, Bacillus Calmette-Gu?rin (BCG), yellow fever, varicella and TY21a typhoid vaccines

• Uncontrolled brain or all leptomeningeal metastases, including patients who continue to require glucocorticoids for brain or leptomeningeal metastases

• Patients who have any severe and/or uncontrolled medical conditions or other conditions that could affect their participation in the study such as:

• Symptomatic congestive heart failure of New York heart Association Class III or IV

• Unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction within 6 months of start of study drug, serious uncontrolled cardiac arrhythmia or any other clinically significant cardiac disease

• Severely impaired lung function

• Uncontrolled diabetes as defined by fasting serum glucose > 1.5 x ULN (Note:

Optimal glycemic control should be achieved before starting trial therapy)

• Active (acute or chronic) or uncontrolled severe infections

• Liver disease such as cirrhosis or severe hepatic impairment (Child-Pugh class C)

• A Hepatitis B/C blood test must be done at screening for all patients; patients who test positive for Hepatitis C antibodies and the Hepatitis B antigen are ineligible

• A known history of human immunodeficiency virus (HIV) seropositivity

• Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of RAD001 (e.g., ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or small bowel resection)

• Impaired lung function: O2 saturation 88% or less at rest on room air by pulse oximetry; if O2 saturation is =< 88% at rest, further pulmonary function tests (PFTs) should be ordered to confirm normal pulmonary function and eligibility

• Patients with an active, bleeding diathesis

• Female patients who are pregnant or breast feeding, or adults of reproductive potential who are not using effective birth control methods; adequate contraception must be used throughout the trial and for 8 weeks after the last dose of study drug, by both sexes (women of childbearing potential [WOCBP] must have a negative urine or serum pregnancy test within 7 days prior to administration of RAD001)

• Male patient whose sexual partner(s) are WOCBP who are not willing to use adequate contraception, during the study and for 8 weeks after the end of treatment

• Patients who have received prior treatment with an mammalian target of rapamycin (mTOR) inhibitor (e.g., sirolimus, temsirolimus, everolimus)

• Patients with a known hypersensitivity to RAD001 (everolimus) or other rapamycins (e.g., sirolimus, temsirolimus) or to its excipients

• History of noncompliance to medical regimens

• Patients unwilling to or unable to comply with the protocol
