|NCT01339052 : Phase II Study of BKM120 for Subjects With Recurrent Glioblastoma|
|Ages||Min: 18 Years Max: N/A|
- Participants must be able to understand and be willing to sign a written informed
- 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
- 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
- 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.
