Brief Summary

BKM120 is a newly discovered drug that has been used in other research studies. Information from those other research studies suggests that BKM120 may help to slow or stop the growth of malignant gliomas. The purpose of this study is to see how well BKM120 works in patients with malignant gliomas. Patients on this study will be treated in two groups: patients who are going to receive surgery and those who will not receive surgery. This study is trying to determine how effective BKM120 is in stopping cancer cells from growing. For patients receiving surgery the research will also try to determine if an effective level of BKM120 can penetrate the brain before surgery.

Detailed Description

OBJECTIVES:

Cohort 1

Primary Objectives

• Evaluate PI3K pathway modulation due to BKM120 in tumor tissue
• Evaluate BKM120 concentration in tumor tissue, plasma, and cerebrospinal fluid

Secondary Objectives

• Evaluate effects of BKM120 on tumor cell proliferation and tumor cell death
• Investigate the safety profile of BKM120 in this population
• Investigate pharmacokinetics of BKM120 in this population

Exploratory Objectives

• Correlate FDG-PET and FLT-PET with pharmacodynamic effects and 6-month progressive-free survival (PFS6)
• Determine the effects of BKM120 on primary GBM cell lines derived from participants and correlate with participant benefit from BKM120 treatment

Cohort 2

Primary Objective

• Investigate the treatment efficacy as measured by 6-month progressive-free survival (PFS6)

Secondary Objectives

• Investigate the radiographic response, progression free survival, overall survival
• Investigate the safety profile efficacy of BKM120 in this population

Exploratory Objectives

• Correlate benefit from BKM120 treatment with molecular genotype of tumor (using immunohistochemistry, mutation analysis and RNA expression profiling), and whole blood proteomics
• Correlate benefit from BKM120 treatment with circulating angiogenic biomarkers
• Utilize advance MRI (perfusion, permeability, diffusion imaging) to determine the effects of BKM120 on tumor vasculature and to correlate with benefit from BKM120 treatment

STATISTICAL DESIGN:

Cohort 1

The primary endpoint for Cohort 1 is modulation of PI3 kinase pathway based on change in immunohistochemistry (IHC) scoring for pAKT. Modulation in scoring as measured by reduction of staining intensity score of one degree or more was reported as a positive response to drug. This portion of the trial would be considered a success if 9 or more participants of 15 participants showed a response. There was a 94% chance of this occurring if the true response rate was 75% and only a 10% chance of this occurring if the true response rate was 40%.

Cohort 2

The primary endpoint for Cohort 2 is the proportion of participants progression free at 6 months (PFS6). Historical comparison data suggest that ineffective therapies in recurrent GBM have a PFS6 rate of approximately 9-16% (Wong 1999; Lamborn 2008). This trial was sized to differentiate between a 15% versus a 32% PFS6. With a total sample size of 50 participants, this design yields at least 90% power with a one sided alpha < 0.1 to detect a true PFS6 rate of at least 32%. If the number of successes was ≥ 12, the therapy would be considered worthy of further study.

Eligibility Criteria

Inclusion Criteria

• Participants must be able to understand and be willing to sign a written informed consent document.
• Subjects must be able to adhere to the dosing and visit schedules, and agree to record medication times accurately and consistently in a daily diary.
• Participants must be at least 18 years old.
• Participants must have a Karnofsky performance status (KPS) ≥ 60. Nature of illness and treatment history
• Participants must have histologically confirmed glioblastoma or variants. Participants will be eligible if the original histology was low-grade glioma and a subsequent histological diagnosis of glioblastoma or variants is made.
• Participants may have had treatment for no more than 1 prior relapse(NOTE: Relapse is defined as progression following initial therapy (i.e., radiation ± chemotherapy)). The intent therefore is that patients had no more than 2 prior therapies (initial and treatment for 1 relapse). If the participant had a surgical resection for relapsed disease and no antitumor therapy was instituted for up to 12 weeks, and the participant undergoes another surgical resection, this is considered as a second relapse. For participants who had prior therapy for a low-grade glioma, the surgical diagnosis of a high-grade glioma will be considered the first relapse).
• Participants must have shown unequivocal evidence for tumor progression by MRI or CT scan.
• For Cohort 2, CT or MRI within 14 days prior to start of study drug. MRIs should include vascular imaging when possible. For Cohort 2, corticosteroid dose must be stable or decreasing for at least 5 days prior to the scan. If steroids are added or the steroid dose is increased between the date of the screening MRI or CT scan and the start of treatment, a new baseline MRI or CT is required. For Cohort 1 subjects, CT or MRI should be performed ideally within 14 days prior to study registration, but because the screening MRI for this subset of subjects will not be used for evaluation of response, it is acceptable for this MRI/CT to have been performed greater than 14 days prior to registration if unavoidable. Furthermore, for this same reason, fluctuation in corticosteroid dose around this MRI does not warrant repeat scan so long as there is documented unequivocal evidence of tumor progression available.
• For Cohort 2, Immunohistochemical or genetic analysis on tumor tissue from a prior surgery must demonstrate activation of the PI3K pathway through one of the following: PIK3CA mutation of PIK3R1 mutation, PTEN negativity (<10% of tumor cells staining) oh immunohistochemistry, PTEN mutation (any), homozygous deletion of PTEN
• Participants must have failed prior radiation therapy and must have an interval of at least 12 weeks from the completion of radiation therapy to study entry.
• Participants must have recovered to a grade 0 or 1 from the toxic effects of prior therapy (with the exception of lymphopenia which is common after therapy with temozolomide).
• From the projected start of scheduled study treatment, the following time periods must have elapsed: 4 weeks or 5 half-lives (whichever is shorter)from any investigational agent, 4 weeks from cytotoxic therapy (except 23 days for temozolomide and 6 weeks from nitrosoureas), 6 weeks from antibodies, or 4 weeks or 5 half-lives (whichever is shorter) from other anti-tumor therapies.
• Participants with prior therapy that included interstitial brachytherapy or stereotactic radiosurgery must have confirmation of progressive disease based upon nuclear imaging, MR spectroscopy, perfusion imaging or histopathology.
• Participants having undergone recent resection of recurrent or progressive tumor will be eligible for Cohort 2 as long as the following conditions apply: a) They have recovered from the effects of surgery; b) Residual disease following resection of recurrent tumor is not mandated for eligibility. To best assess the extent of residual disease postoperatively, an MRI or CT scan should ideally been performed no later than 96 hours following surgery or at least 28-days postoperatively, but scans performed outside of this window are considered acceptable if no alternative is available. In either case, the baseline/screening MRI must be performed within 14 days prior to registration. If the participant is taking corticosteroids, the dose must be stable or decreasing for at least 5 days prior to the scan. If steroids are added or the steroid dose is increased between the date of the screening MRI or CT scan and the start of treatment, a new baseline MRI or CT is required.
• Participants must have sufficient tissue from prior surgery for confirmation of diagnosis and correlative studies. Submission of tissue is to occur within 30 days after registration. The following amount of tissue is required: a) 25 unstained formalin fixed paraffin embedded (FFPE) sections (standard 4-5 micrometer thickness AND b)one of the following: i) At least 200 micrograms of frozen tissue OR ii)At least 10 (preferably 20) unstained FFPE sections of 10 micrometer thickness OR iii) At least 8 tissue cores from an FFPE block (200 micrometer total thickness of tissue from a block with a total surface area of 0.5 cm2)
• Clinical laboratory tests within 14 days prior to enrollment meeting the criteria listed in the protocol
• Cardiovascular assessment: baseline MUGA or Echocardiogram must demonstrate LVEF ≥ 50 %
• Electrocardiogram must demonstrate QTc interval of less than 480 msec
• Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum 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.
• Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, must use highly effective contraception (defined in protocol) during study treatment and for 16 weeks after study discontinuation.
• Women of child-bearing potential must have a negative serum pregnancy test at screening and within 48 hours prior to dosing with the study drug.
• Fertile males, defined as all males physiologically capable of conceiving offspring, must use condom during study treatment and for 16 weeks after study discontinuation and should not father a child in this period.
• Female partner of male study subject should use highly effective contraception while receiving study agent and for 16 weeks after final dose of study therapy.

• A participant who is deemed by the site Investigator to be an appropriate candidate for surgical resection may be enrolled in the Cohort 1 preoperative study.
• There must be sufficient recurrent tumor to allow at least 400mg of tissue to be collected ( 2 X 0.5 cm3) for pharmacokinetic and pharmacodynamic analysis.
• Central Immunohistochemical analysis (by Dr. Ligon at DFCI) on tumor tissue from an earlier surgery must indicate pAKT positivity (1-2+ on a 0-2+ scale). [Cohort I patients' tissue may also demonstrate activation of the PI3K pathway via one of the criteria listed for Cohort 2 participants, but this is not mandatory.]
