Trial Information

Phase I/II Study of Bevacizumab Plus Daily Temozolomide and Vorinostat for Recurrent Malignant Glioma Patients

Inclusion Criteria:

- Patients must have histologically confirmed diagnosis of malignant glioma and
radiographic evidence of recurrence or disease progression (defined as either a
greater than 25% increase in the largest bidimensional product of enhancement or a
new enhancing lesion) following prior therapy. In addition, the following must be

Phase I specific

- WHO grade 3 or 4 malignant glioma Phase II specific

- WHO grade 4 malignant glioma

- No more than 2 prior episodes of disease progression

Common to both Phase I and Phase II

- Age * 18 years

- KPS (Karnofsky Performance Scale) ≥ 70%

- An interval of at least 4 weeks between prior surgical resection or one week from
stereotactic biopsy

- An interval of at least 12 weeks from the end of prior radiotherapy unless there is a
new area of enhancement consistent with recurrent tumor outside of the radiation
field, or there are progressive changes on MRI on at least two consecutive MRI scans
at least four weeks apart, or there is biopsy-proven tumor progression

- An interval of at least 4 weeks from prior chemotherapy (6 weeks for nitrosoureas) or
investigational agent unless the patient has recovered from all anticipated
toxicities associated with that therapy

- Hematocrit ≥ 29%, ANC ≥ 1,000 cells/*l, platelets ≥ 100,000 cells/*l

- Serum creatinine < 1.5 times upper limit of normal, serum SGOT < 2.5 times upper
limit of normal and bilirubin < 2.0 times upper limit of normal

- Signed informed consent approved by the Institutional Review Board prior to patient

- No evidence of hemorrhage on the baseline MRI or CT scan other than those that are
stable grade 1

- If sexually active, patients will take contraceptive measures for the duration of the
treatments. Medically acceptable contraceptives include:

1. surgical sterilization (such as a tubal ligation, hysterectomy, vasectomy),

2. approved hormonal contraceptives (such as birth control pills, patches,
implants or injections),

3. barrier methods (such as a condom or diaphragm) used with a spermicide, or

4. an intrauterine device (IUD).

Exclusion Criteria:

- Prior therapy with histone deacetylase inhibitors; valproic acid is not permitted and
patients previously treated with valproic acid must be off valproic acid for at least
30 days prior to initiation of study medication

- Co-medication that may interfere with study results; e.g. immuno-suppressive agents
other than corticosteroids

- Active infection requiring intravenous antibiotics

- Progression on prior bevacizumab or daily temozolomide

- Grade 3 or greater toxicity related to prior bevacizumab or daily temozolomide

- Requires therapeutic anti-coagulation with warfarin

- Life expectancy of <12 weeks

- Active malignancy other than basal or squamous cell skin ca or carcinoma in situ of
cervix within 5 years

- Subject recruitment and compensation - subjects will be recruited for this study as

- Upon determination that a subject's tumor histology and/or radiographic findings
are compatible with the eligibility criteria of this protocol, the clinical
study will be briefly explained to the subject by the subject's physician, who
will be a physician at the Brain Tumor Center at Duke.

- If the subject indicates interest in study participation, subject education
sheets and the informed consent document will be provided to the subject as
these provide the most comprehensive explanation of the study in lay terms.

- If the subject shows continued interest, the PI or designee will thoroughly
explain the required elements of the consent form and all aspects of the study
to the subject including inclusion/exclusion criteria, risks, benefits, and
alternatives to study participation.

- Subjects will not be paid to take part in this research study.

The list of subjects pre-screened will be kept in an Excel spreadsheet in the study
coordinator's office. The PC (personal computer) is on the DUHS (Duke University Health
System) network protected by a user ID (identifier) and password and the office is locked
when it is unoccupied. All screened subjects who are not enrolled in the study will have
all identifiers destroyed immediately.

Type of Study:


Study Design:

Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

Phase I: Determination of the Maximum Tolerated Dose (MTD)

Outcome Description:

The MTD is based upon dose-limiting toxicities (DLTs) experienced during Cycle 1 of treatment. The MTD is the dose level at which 0/6 or 1/6 patients experience DLT with at least two patients experiencing DLT at the next higher dose level. Using Common Terminology Criteria for Adverse Events (CTCAE) version 3.0, DLTs are defined as: Grade 4 neutropenia lasting greater than 5 days; Grade 3 thrombocytopenia; the occurrence of non-hematologic Grade 3 or greater drug-related adverse events excluding Grade ≥ 3 elevation in alkaline phosphatase, Grade ≥ 3 nausea or vomiting unless occurring despite the use of standard anti-emetics or Grade 3 diarrhea unless occurring despite standard anti-diarrheal therapy; > 14 day delay to re-treat due to failure to resolve drug-related toxicity to re-treatment criteria or pre-treatment baseline.

Outcome Time Frame:

Cycle 1 (28 days)
