  Purpose
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.

Primary Outcome Measures:
  • Change in pAKT (S473) Immunohistochemistry (IHC) Score From Baseline to Surgery [Cohort 1] [ Time Frame: Samples were collected at baseline and at surgery (resected surgical tumor specimen) which occurred after up to 12 days of BKM120 treatment. ]
    pAKT response was determined by pathologist-performed semi-quantitative IHC scoring for pAKT using previously established methods for glioblastoma (GBM) patients. Sample staining scored for intensity on a 0-2+ scale (0 none, 1+ weak positive, 2+ strong positive). Change in pAKT IHC score was the difference in score from baseline to surgery. Participants were classified into 3 groups: a reduction of staining score of one degree or more (considered a response), an increase in score and no change in score.

  • 6-Month Progression-Free Survival (PFS6) [Cohort 2] [ Time Frame: Participants were assessed radiologically every other cycle on treatment; Relevant for this outcome is up to month 6 evaluation. ]
    PFS6 is the proportion of participants remaining alive and progression-free at 6-months from cycle 1 day 1 of BKM120 treatment. Progressive disease is defined using RANO (Response Assessment in Neuro-Oncology) criteria (Wen et al JCO 2010), which takes modified Macdonald Criteria and adds assessment of non-enhancing lesions. Per RANO, progressive disease (PD) is defined either as > 25% increase in sum of the products of perpendicular diameters of enhancing lesions on stable or increasing doses of corticosteroids, or one or more of the of the following: 1) Significant increase in T2/FLAIR non-enhancing lesion on stable or increasing doses of corticosteroids steroids not due to co-morbid events; 2) Any new lesion; 3) Clear clinical deterioration not attributable to other causes apart from the tumor; or 4) Failure to return for evaluation due to death or deteriorating condition.

  • BKM120 Brain-to-Plasma Ratio at Time of Surgery [Cohort 1] [ Time Frame: Samples were collected at surgery (surgical tumor specimen and plasma sample) which occurred after up to 12 days of BKM120 treatment. ]
    Levels of BKM120 were determined by liquid chromatography coupled with tandem mass spectrometry. BKM120 tumor-to-plasma ratio at time of surgery was calculated based on these levels.

  • BKM120 Tumor Tissue Concentration at Time of Surgery [Cohort 1] [ Time Frame: Samples were collected at surgery (resected surgical tumor specimen) which occurred after up to 12 days of BKM120 treatment. ]
    Levels of BKM120 were determined by liquid chromatography coupled with tandem mass spectrometry.

  • BKM120 Plasma Concentration at Time of Surgery [Cohort 1] [ Time Frame: Samples were collected at surgery which occurred after up to 12 days of BKM120 treatment. ]
    Levels of BKM120 were determined by liquid chromatography coupled with tandem mass spectrometry.


Secondary Outcome Measures:
  • % Ki-67 Reduction Using Immunohistochemistry (IHC) [Cohort 1] [ Time Frame: Samples were collected at baseline (archival tumor specimen) and at surgery (surgical tumor specimen) which occurred after up to 12 days of BTK120 treatment. ]
    Tumor cell proliferation and tumor cell death was using immunohistochemistry for Ki-67 based on established methods. Percent reduction was based on Ki-67 levels at baseline and at surgery.

  • Radiographic Response [Cohort 2] [ Time Frame: Participants were assessed radiologically every other cycle on treatment. Cohort 2 participants were on treatment up to 9.2 months. ]
    Radiographic response was based on RANO (Response Assessment in Neuro-Oncology) criteria. Per RANO, complete response (CR): 1) Complete disappearance of all enhancing measurable and non-measurable disease sustained for at least 4 weeks, 2) No new lesions, 3) All lesions assessed using the same techniques as baseline, 4) No steroid use (or on physiologic replacement doses only), 5) Stable or improved non-enhancing (T2/FLAIR) lesions and 6) Stable or improved clinically; partial response (PR): 1) >/= 50% decrease compared to baseline in the sum of products of perpendicular diameters of all measurable enhancing lesions (sum LD) sustained for at least 4 weeks and 2) No progression; progressive disease (PD): 1) > 25% increase sum LD and/or 2) significant increase in T2/FLAIR, 3) any new lesion, 4) clear clinical deterioration; stable disease (SD): none of the above.

  • Maximum Observed Plasma Concentrations (Cmax) of BKM120 Day 1 and Day 8 [Cohort 1] [ Time Frame: On days 1 and 8 (+/- 1 day) prior to surgery, 5 blood samples were collected at the following timepoints: pre-dose, and at 0.5, 1.5, 3, and 5 hours post-dose. ]
    Plasma concentrations of BKM120 were analyzed by a validated liquid chromatography-tandem mass spectrometry assay developed by Novartis Pharma AG. Standard Pk parameters were determined using non-compartmental methods.

  • Time to Maximum Observed Plasma Concentration (Tmax) of BKM120 Day 1 and Day 8 [Cohort 1] [ Time Frame: On days 1 and 8 (+/- 1 day) prior to surgery, 5 blood samples were collected at the following timepoints: pre-dose, and at 0.5, 1.5, 3, and 5 hours post-dose. ]
    Plasma concentrations of BKM120 were analyzed by a validated liquid chromatography-tandem mass spectrometry assay developed by Novartis Pharma AG. Standard Pk parameters were determined using non-compartmental methods.

  • Area Under the Concentration Curve From Time 0 to Last Concentration (AUC0-5h) of BKM120 Day 1 and Day 8 [Cohort 1] [ Time Frame: On days 1 and 8 (+/- 1 day) prior to surgery, 5 blood samples were collected at the following timepoints: pre-dose, and at 0.5, 1.5, 3, and 5 hours post-dose. ]
    Plasma concentrations of BKM120 were analyzed by a validated liquid chromatography-tandem mass spectrometry assay developed by Novartis Pharma AG. Standard Pk parameters were determined using non-compartmental methods.

  • Overall Survival (OS) [Cohort 2] [ Time Frame: Participants were followed long-term for survival via medical record review. Cohort 2 participants were followed for survival up to 52 months in this study cohort. ]
    Overall survival is defined as the time from date of first dose to death or date last known alive and estimated using Kaplan-Meier (KM) methods.

  • Progression-Free Survival (PFS) [Cohort 2] [ Time Frame: Participants were assessed radiologically every other cycle on treatment and off-treatment via medical record review until death. Cohort 2 participants were followed for progression-free survival up to 12 months in this study cohort. ]
    PFS is defined as the time from first dose to the earliest documentation of disease progression or death. Participants alive without evidence of PD were censored at the date of last disease assessment. Progressive disease was established based on Response Assessment in Neuro-Oncology (RANO) criteria (Wen et al JCO 2010). See outcome measure #2.

  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
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.

Cohort 1 Inclusion Criteria (In addition to the general eligibility criteria, participants in the Cohort 1 preoperative portion of the study must meet the following criteria on screening examination to be eligible):

  • 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.]
