IRB RTOG 0913
Hospital Fairview, Hillcrest, Independence, Main Campus, North Coast Cancer, Strongsville, Wooster
Phase Phase 1, Phase 2
Drug RAD-001, Temozolomide
- To define the maximum tolerated dose of RAD001 (up to established dose of 10 mg/day) when combined with concurrent radiation and temozolomide in newly diagnosed GBM.
- To characterize the safety profile of RAD001 in combination with radiation and temozolomide.
- To determine the efficacy of RAD001 in combination with radiation and temozolomide followed by RAD001 in combination with temozolomide in patients with newly diagnosed GBM as measured by progression-free survival.
- To determine overall survival in newly diagnosed GBM treated with the study regimen.
- To further evaluate the safety profile of RAD001 in combination with radiation and temozolomide in this patient population.
- To determine if activation of the Akt/mTOR axis predicts response to RAD001 therapy.
- To determine if there is an association between tumor MGMT gene methylation status and response to RAD001.
- Histologically proven diagnosis of glioblastoma (WHO grade IV) confirmed by central pathology review prior to Step 2 registration. Since gliosarcoma is a variant of glioblastoma, gliosarcoma is also an eligible diagnosis.
- Tumor tissue available for correlative studies (Required ONLY in phase II portion, as described below and in Section 10).
- Patients must have at least 1 block of tissue; if a block cannot be submitted, two tissue specimens punched with a skin punch (2 mm diameter) from the tissue block containing the tumor may be submitted (see Section 10).
- Diagnosis must be made by surgical excision, either partial or complete. Stereotactic biopsy or CUSA (Cavitron ultrasonic aspirator)-derived tissue is not allowed for patients on Phase II, as it will not provide sufficient tissue for the required MGMT and pAKT/pMTOR analyses.
- The tumor must have a supratentorial component
- Patients must have recovered from the effects of surgery, postoperative infection, and other complications.
- A diagnostic contrast-enhanced MRI or CT scan (if MRI is not available due to non-compatible devices) of the brain must be performed preoperatively and postoperatively. The postoperative scan must be done within 28 days prior to step 2 registration, ,preferably within 96 hours of surgery. Preoperative and postoperative scans must be the same type.
- Patients unable to undergo MR imaging because of non-compatible devices can be enrolled, provided pre- and post-operative contrast enhanced CT scans are obtained and are of sufficient quality.
- History/physical examination within 14 days prior to step 2 registration
- Neurologic examination within 14 days prior to step 2 registration
- Documentation of steroid doses within 14 days prior to step 2 registration
- Karnofsky performance status ≥ 70
- Age ≥ 18 years
- CBC/differential obtained within 14 days prior to step 2 registration, with adequate bone marrow function defined as follows:
- Absolute neutrophil count (ANC) ≥ 1,800 cells/mm3;
- Platelets ≥ 100,000 cells/mm3;
- Hemoglobin ≥ 10.0 g/dl (Note: The use of transfusion or other intervention to achieve Hgb ≥ 10.0 g/dl is acceptable.)
- PT/INR ≤ 1.5.
- Anticoagulation is allowed if target INR ≤ 1.5 on a stable dose of warfarin or on a stable dose of LMW heparin for > 2 weeks at the time of enrollment.
- Adequate renal function, as defined below:
- BUN ≤ 30 mg/dl within 14 days prior to step 2 registration
- Serum creatinine ≤ 1.5 x ULN within 14 days prior to step 2 registration
- Adequate hepatic function, as defined below:
- Bilirubin ≤ 1.5 x normal range within 14 days prior to step 2 registration
- ALT ≤ 2.5 x normal range within 14 days prior to step 2 registration
- AST ≤ 2.5 x normal range within 14 days prior to step 2 registration
- Fasting serum cholesterol ≤300 mg/dL OR ≤7.75 mmol/L AND fasting triglycerides ≤ 2.5 x ULN. NOTE: If one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication.
- For females of child-bearing potential, negative serum pregnancy test within 14 days prior to step 2 registration
- Women of childbearing potential and male participants must practice adequate contraception
- Patient must provide study-specific informed consent prior to registration
- Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years (For example, carcinoma in situ of the breast, oral cavity, or cervix are all permissible)
- Recurrent or multifocal malignant glioma
- Metastases detected below the tentorium or beyond the cranial vault
- Prior use of Gliadel wafers or any other intratumoral or intracavitary treatment
- Prior radiotherapy to the head or neck (except for T1 glottic cancer), resulting in overlap of radiation therapy fields
- Prior chemotherapy or radiosensitizers for cancer of the head and neck region; note that prior chemotherapy for a different cancer is allowable, except prior temozolomide or RAD001.
- Prior radiation therapy or chemotherapy for glioblastoma
- Severe, active co-morbidity, defined as follows:
- Symptomatic congestive heart failure of New York heart Association Class III or IV
- Unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction within the last 6 months, serious uncontrolled cardiac arrhythmia or any other clinically significant cardiac disease
- Severely impaired lung function as defined as spirometry and DLCO that is 50% of the normal predicted value and/or 02 saturation that is 88% or less at rest on room air
- Uncontrolled diabetes as defined by fasting serum glucose >1.5 x ULN
- Active (acute or chronic) or uncontrolled severe infections requiring intravenous antibiotics
- Liver disease such as cirrhosis, chronic active hepatitis or chronic persistent hepatitis
- Acquired immune deficiency syndrome (AIDS) based upon current CDC definition or known HIV seropositivity; note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with HIV/AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive.
- Active connective tissue disorders, such as lupus or scleroderma, that in the opinion of the treating physician may put the patient at high risk for radiation toxicity
- Other major medical illnesses or psychiatric impairments that in the investigator's opinion will prevent administration or completion of protocol therapy
- Pregnancy or women of childbearing potential and men who are sexually active and not willing/able to use medically acceptable forms of contraception; this exclusion is necessary because the treatment involved in this study may be significantly teratogenic
- Women who are breast feeding, due to possible adverse effects on the infant
- Prior allergic reaction to temozolomide
- Patients who have received prior treatment with an mTOR inhibitor (e.g., sirolimus, temsirolimus, everolimus) or with a known hypersensitivity to these agents or to their excipients
- Treatment on any other therapeutic clinical protocol
- 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)
- Concurrent use of enzyme-inducing anti-epileptic drugs (EIAEDs) (See Appendix V)
- Patients previously receiving these agents must have discontinued their use at least 14 days prior to step 2 registration
- History of deep vein thrombosis or pulmonary embolism.
