Background:
- AZD8055 is an experimental cancer treatment drug that works by inhibiting a protein called
mTOR, which is known to promote tumor cell and blood vessel growth and to control tumor s
energy and nutrient levels. AZD8055 is the first drug that inhibits both types of mTOR
protein and is expected to be more effective than prior mTOR inhibitors. However, more
research is needed to determine its safety and effectiveness in treating brain tumors known
as gliomas that have not responded to standard treatments.
Objectives:
- To evaluate the safety and effectiveness of AZD8055 in individuals with gliomas that have
not responded to standard treatments.
Eligibility:
- Individuals at least 18 years of age who have been diagnosed with gliomas that have not
responded to standard chemotherapy, surgery, or radiation.
Design:
- Participants will be screened with a physical examination, medical history, blood tests,
and tumor imaging studies.
- Participants will be separated into two treatment groups: one group that will receive
surgery to remove the glioma and one that will not have surgical treatment.
- Participants in the nonsurgical treatment group will take AZD8055 by mouth daily for a
42-day cycle of treatment. Participants will keep a diary to record doses and keep track
of any side effects.
- Participants in the surgical treatment group will take AZD8055 by mouth daily for 7
days, and then will have tumor removal surgery. At least 3 weeks after surgery,
participants will resume doses of AZD8055 and will continue to take the drug for as long
as the tumor does not recur.
- During treatment, participants will have regular visits to the clinical center,
involving frequent blood and urine tests and other examinations to monitor the effects
of treatment. Participants will have imaging studies to study the cancer's response to
the treatment.
- Participants will continue to have cycles of treatment for as long as the treatment
continues to be effective and the side effects are not severe enough to stop
participation in the study....

Eligibility |
- INCLUSION CRITERIA: - Patients with histologically proven malignant primary gliomas who have progressive disease after radiotherapy will be eligible for this protocol. These include glioblastoma (GBM), gliosarcoma, anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), anaplastic mixed oligoastrocytoma (AMO), and malignant glioma/astrocytoma NOS. Additionally, patients with progressive low-grade gliomas and patients with infiltrative brainstem gliomas, diagnosed radiographically rather than by biopsy, will be eligible. - Patients must have an MRI scan performed within 14 days prior to registration and on a fixed dose of steroids for at least 5 days. If the steroid dose is increased between the date of imaging and registration a new baseline MRI is required. - Patients having undergone recent resection of recurrent or progressive tumor will be eligible for the non-surgical arm as long as all of the following conditions apply: 1. Patients will be eligible four weeks after surgery if they have recovered from the effects of surgery. 2. Residual disease following resection of recurrent tumor is not mandated for eligibility into the study. To best assess the extent of residual disease postoperatively, an MRI should be done: - no later than 96 hours in the immediate post-operative period or - at least 4 weeks post-operatively, and - within 14 days of registration, and - on a stable steroid dosage for at least 5 days. If the 96 hour scan is more than 14 days before registration, the scan needs to be repeated. If the steroid dose is increased between the date of imaging and registration, a new baseline MRI is required on a stable steroid dosage for at least 5 days. - Patients must have failed prior radiation therapy. - All patients or their previously designated DPA (if the patient is deemed by the treating physician to be cognitively impaired or questionably impaired in such a way that the ability of the patient to give informed consent is questionable) must sign an informed consent indicating that they are aware of the investigational nature of this study. - Patients must be greater than or equal to 18 years old, and must have a life expectancy > 8 weeks. - Patients must have a Karnofsky performance status of greater than or equal to 60. - Patients must be at least 4 weeks from radiation therapy. Additionally, patients must be at least 6 weeks from nitrosoureas, 4 weeks from temozolomide, 3 weeks from procarbazine, 2 weeks from vincristine and 2 weeks from last bevacizumab administration. Patients must be at least 4 weeks from other cytotoxic therapies not listed above and 2 weeks for non-cytotoxic agents (e.g., interferon, tamoxifen) including investigative agents. With the exception of alopecia, all toxicities from prior therapies should be resolved to CTCAE less than or equal to grade 1. - Patients must have adequate bone marrow function (WBC greater than or equal to 3,000/microL, ANC greater than or equal to 1,500/mm(3), platelet count of greater than or equal to 100,000/mm(3), and hemoglobin greater than or equal to 9 gm/dl), adequate liver function (AST, ALT and alkaline phosphatase 2.5 less than or equal to ULN and bilirubin less than or equal to 1.5 times ULN), and adequate renal function (creatinine less than or equal to 1.5 times ULN and/or creatinine clearance greater than or equal to 50 cc/min calculated by Cockcroft-Gault) before starting therapy. Patients must also have serum potassium greater than or equal to 3.5 mmol/L, magnesium greater than or equal to 0.75 mmol/L and calcium levels within normal levels; supplementation is allowed. In cases where the serum calcium is below the normal range, 2 options would be available: 1) the calcium adjusted for albumin is to be obtained and substituted for the measured serum value. Exclusion is to then be based on the adjusted for albumin values falling below the normal limit. 2) Determine the ionized calcium levels. Exclusion is then to be based if these ionized calcium levels are out of normal range despite supplementation. These tests must be performed within 14 days prior to registration. Eligibility level for hemoglobin may be reached by transfusion. - Patients must either not be receiving steroids, or be on a stable dose of steroids for at least five days prior to registration. - This study was designed to include women and minorities, but was not designed to measure differences of intervention effects. Males and females will be recruited with no preference to gender. No exclusion to this study will be based on race. Minorities will actively be recruited to participate. - Male patients should be willing to use barrier contraception (condoms). - Female patients should be using adequate contraceptive measures, should not be breast feeding and must have a negative pregnancy test prior to start of dosing if of child-bearing potential or must have evidence of non-childbearing potential by fulfilling one of the following criteria at screening: - Post-menopausal defined as aged more than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments. - Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy or bilateral salpingectomy but not tubal ligation. - A 12 lead electrocardiogram (ECG) to be performed within 2 weeks of trial entry with QTc less than or equal to 470 msec. - Patients must have normal left ventricular ejection fraction (LVEF greater than or equal to 55% or normal by NIH Clinical Center criteria). EXCLUSION CRITERIA: - Patients who, in the view of the treating physician, have significant active hepatic, renal, pulmonary or psychiatric diseases are ineligible. - Prior treatment with AZD8055 or AZD2014. - History of hypersensitivity to active or excipients of AZD8055 or drugs with a similar chemical structure or class to AZD8055. - Clinically significant cardiovascular event (e.g. myocardial infarction, angina pectoris, coronary artery bypass graft, angioplasty, vascular stent, superior vena cava syndrome (SVC), New York Heart Association (NYHA) classification of heart disease greater than or equal to 2 within 6 months before entry; or presence of cardiac disease that, in the opinion of the investigator, increases the risk of ventricular arrhythmia. - Hemorrhagic or ischemic stroke, including transient ischemic attacks and other central nervous system bleeding in the preceding 6 months that were not related to glioma surgery. History of prior intratumoral bleeding is not an exclusion criteria; patients with history of prior intratumoral bleeding, however, need to undergo a non-contrast head CT to exclude acute blood. - Ventricular arrhythmias requiring continuous therapy or asymptomatic sustained ventricular tachycardia within 12 months before study entry. Atrial fibrillation, controlled on medication is not excluded. Patients with significant ECG abnormalities such as complete left bundle block and third degree heart block are not eligible. - QTc prolongation with other medications that required discontinuation of that medication. - Congenital long QT syndrome or 1st degree relative with unexplained sudden death under 40 years of age. - QTc with Bazett s correction that is unmeasurable, or >470 msec on screening ECG. (Note: If a subject has a QTc interval >470 msec on screening ECG, the screen ECG may be repeated twice (at least 24 hours apart). The average QTc from the three screening ECGs must be less than or equal to 470 msec in order for the subject to be eligible for the study. Patients who are receiving a drug that has a risk of QTc prolongation are excluded if QTc is greater than or equal to 460 msec. - Any concurrent medication that may cause QTc prolongation or induce Torsades de Pointes Drugs, that in the investigator s opinion cannot be discontinued are allowed; however, must be monitored closely. - Concomitant medications that are moderate or potent inducers of CYP3A4 or CYP2C8 function (with the exception of dexamethasone) are not permitted within the specified wash-out periods prior to or during treatment with AZD8055. - Patients with uncontrolled hypercholesterolemia or hypertriglyceridemia (fasting state) despite lipid-lowering therapy. - Patients with manifest diabetes mellitus type 1 and patients with uncontrolled diabetes mellitus type 2 or corticosteroid-induced hyperglycemia despite optimal therapy. - Refractory nausea and vomiting or significant gastrointestinal impairment, as judged by the investigator, that would significantly affect the absorption of AZD8055, including the ability to swallow the tablet whole. - Patients known to have active hepatitis B or C or HIV on anti-retrovirals (testing is not required for entry on study). - Other concomitant anti-cancer therapy except corticosteroids. - Patients with a peripheral neuropathy CTCAE > 1 in the prior 4 weeks or active muscle diseases (including dermatomyositis, polymyositis, inclusion body myositis, muscular dystrophy and metabolic myopathy) or family history of myopathy. - Patients with pre-existing renal disease including glomerulonephritis, nephritic syndrome, Fanconi syndrome or renal tubular acidosis. - Evidence of active infection or active bleeding diatheses. - Patients with an abnormal LVEF on echocardiogram at baseline. - Women who are currently pregnant or breast feeding. - Patients known to have a malignancy (other than their malignant glioma) that has required treatment in the last 12 months and/or is expected to require treatment in the next 12 months (except for non-melanoma skin cancer, carcinoma in situ in the cervix or ductal carcinoma in situ). - Major surgery within 4 weeks or incompletely healed surgical incision before starting therapy. |
