Clinical trial: Temsirolimus and Perifosine in Treating Patients With Recurrent or Progressive Malignant Glioma

Summary: This phase I/II trial studies the side effects and best dose of temsirolimus when given together with perifosine and to see how well it works in treating patients with recurrent or progressive malignant glioma. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as perifosine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving temsirolimus with perifosine may be an effective treatment for malignant glioma.

Detailed description: PRIMARY OBJECTIVES:
  I. Define the maximum tolerated dose (MTD) of temsirolimus in combination with perifosine in patients with recurrent or progressive malignant glioma who are not taking enzyme-inducing anti-epileptic drugs (EIAEDs). (Phase I) II. Determine the efficacy of temsirolimus in combination with perifosine in patients with recurrent/progressive glioblastomas (GBMs) not taking EIAEDs as measured by 6 month progression-free survival (6mPFS) and radiographic response rates. (Phase II)
  SECONDARY OBJECTIVES:
  I. Characterize the safety profile of perifosine and temsirolimus. II. Estimate median overall and progression-free survival. III. Explore the association of pre-treatment molecular phenotype with response to treatment.
  IV. Explore molecular effects during treatment including phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR)/ribosomal protein S6 kinase (S6K) and rat sarcoma (RAS)/mitogen-activated protein kinase kinase (MEK)/mitogen-activated protein kinase (ERK) signaling, proliferation, and apoptosis.
  OUTLINE: This is a phase I dose-escalation study of temsirolimus, followed by a phase II study.
  PHASE I: Patients receive temsirolimus intravenously (IV) over 30 minutes on days 1, 8, 15, and 22 and perifosine orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
  PHASE II: Patients receive temsirolimus and perifosine as in phase I. Some patients may also undergo cytoreductive surgery.
  After completion of study therapy, patients are followed up every 3 months.

Eligibility: Inclusion Criteria:

  -  Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
  -  Women of childbearing potential must have a negative beta-human chorionic gonadotropin (B-HCG) pregnancy test documented within 7 days prior to treatment
  -  Women must agree not to breast feed
  -  Patients must have the ability to understand and the willingness to sign a written informed consent document
  -  Measurable disease is not required for eligibility in patients who recently underwent resection as long as progressive disease led to the surgery, and the histology of the most recent surgery documented recurrent/progressive/persistent malignant glioma
  -  If cytoreductive surgery is planned for tumor recurrence at the time of enrollment, such patients may be eligible for the surgical substudy (Phase II only), taking temsirolimus + perifosine pre-operatively and then re-initiating such therapy after recovering from the effects of surgery
  -  PHASE I: Patients must have a EITHER
  -  Histologically confirmed intracranial malignant glioma of the following types: glioblastoma, anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), anaplastic oligo-astrocytoma (AOA) also called anaplastic mixed gliomas, malignant glioma NOS (not otherwise specified); patients will be eligible if the original histology was low-grade glioma and a subsequent histological diagnosis of a high grade (malignant) glioma is made; OR
  -  Histologically confirmed low grade (World Health Organization [WHO] grade II) gliomas (such as low grade astrocytoma, low grade oligodendroglioma, low grade oligo-astrocytoma (mixed gliomas), or low grade glioma NOS) IF there is radiographic evidence by MRI or CT of malignant transformation but histologic confirmation of high grade (malignant) transformation would not be otherwise undertaken for routine clinical care; inclusion of patients in this group will allow increased accrual rapidity by enrolling patients who are otherwise ineligible for almost all malignant glioma trials yet whom are treated presumptively for malignant glioma
  -  PHASE II: Patients must have a histologically confirmed intracranial malignant glioma of the following types: glioblastoma, anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), anaplastic oligo-astrocytoma (AOA) also called anaplastic mixed gliomas, malignant glioma NOS (not otherwise specified); patients will be eligible if the original histology was low-grade glioma and a subsequent histological diagnosis of a high grade (malignant) glioma is made
  -  PHASE II (patients enrolling on the surgical substudy to evaluate tissue correlates): Patients eligible for the surgical subset have been identified as candidates for cytoreductive surgery by the treating physician and/or based on discussion in a multidisciplinary tumor board, with the input of other surgeons as well as that of the neuro-oncologists involved in the trial; for the patients in the preoperative component, a scan showing progression is required but stable corticosteroids are not required; following surgery, a scan should be done less than 96 hours after surgery; if this is not performed, then a new baseline scan should be performed at least 4 weeks after surgery to avoid misinterpretation of post-operative changes as enhancing disease; this scan will serve as the new baseline before restarting treatment post-operative, and it must be performed on a stable or decreasing dose of corticosteroids; (as above, regarding the baseline MRI or CT scan prior to registration, patients in the Phase II component who are NOT participating in the pre-operative component of the study should be on a steroid dose that has been stable for at least 5 days prior to the scan; if the corticosteroid dose is increased between the date of imaging and registration a new baseline MR/CT is required)
  -  PHASE II (patients enrolling on the surgical substudy to evaluate tissue correlates): Post-operatively, treatment with temsirolimus and perifosine must re-start no later than the 14th day after the scan; if the 96-hour scan is more than 14 days old before treatment is initiated, the scan needs to be repeated on a stable or decreasing steroid dose; treatment must start no later than 56 days after surgery
  -  PHASE II (patients previously treated with bevacizumab or other direct inhibitors of VEGF/VEGFR including Aflibercept (VEGF-Trap) and cediranib and XL-184 (BMS 907351): There is no limit on such therapy for patients accrued to phase I; for phase II, historical controls for this group of patients is poorly defined; therefore, we will accrue up to 15 patients who received prior treatment with direct VEGF/VEGFR inhibitors in order to gain preliminary data for use as a comparison group in a follow up study; all other inclusion/exclusion criteria also apply to this cohort
  Exclusion Criteria:
  -  Patients may not be receiving any other investigational agents
  -  Patients must not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to temsirolimus or perifosine
  -  Patients must not be taking EIAED; if previously on an EIAED, the patient must be off of it for at least two weeks prior to treatment on study
  -  Patients must not have 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
  -  Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with temsirolimus and perifosine
  -  Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible
  -  PHASE II: Patients may not have received prior treatment with mTOR inhibitors such as temsirolimus, rapamycin (sirolimus), or RAD001 (everolimus); any question regarding the definition of mTOR inhibiting therapy must be discussed with the PI; such prior therapy is allowed for the phase I component
  -  PHASE II: Patients may not have previously received perifosine or other AKT targeting agents; any question regarding the definition of AKT targeting therapy must be discussed with the PI; such prior therapy is allowed for the phase I component
  -  PHASE II: Patients must not have received prior treatment with convection enhanced delivery, other catheter based intra-tumoral treatment, or carmustine (BCNU)/Gliadel wafers; such prior therapy is allowed for the phase I component
  -  PHASE II: Patients with prior therapy that included stereotactic radiosurgery (including gamma-knife or cyber-knife) during therapy for newly diagnosed or recurrent disease, or re-irradiation of any type, must have confirmation of true progressive disease rather than radiation necrosis based upon surgical documentation of recurrent/progressive disease; imaging with magnetic resonance (MR) spectroscopy, PET, or other techniques is not adequate to exclude radiation necrosis for this study; such prior therapy is allowed for the phase I component and does not require surgical documentation of disease
  -  PHASE II: Patients with a history of any other cancer (except non-melanoma skin cancer or carcinoma in-situ of the cervix), unless in complete remission and off of all therapy for that disease for a minimum of 3 years are ineligible for the phase II study but are eligible for the phase I component
