- Patients must have a Karnofsky performance status (KPS) equal or greater than 60
- At the time of registration:
Show all 29Show fewer
- Patients must have recovered from the toxic effects of prior therapy to < grade 2 toxicity per CTC version 4 (except deep vein thrombosis )
- 28 days from any investigational agent,
- 4 weeks (28 days) from prior cytotoxic therapy,
- 2 weeks (14 days) from vincristine,
- 6 weeks (42 days) from nitrosoureas,
- 3 weeks (21 days) from procarbazine administration,
- greater than or equal to1 week (7 days) for non-cytotoxic agents, e.g., interferon, tamoxifen, thalidomide, cis-retinoic acid, etc. (radiosensitizer does not count).
- Patients who receive anticancer agents for non-therapeutic purposes unrelated to this study (such as presurgically for obtaining pharmacology data for the agent) will be eligible to enter the study provided they have recovered from the toxic effects of the agent if any. Any questions related to the definition of noncytotoxic agents should be directed to the Study Chair.
- Patients must have adequate bone marrow function (ANC greater than or equal to 1,500/mm3, platelet count of greater than or equal to 100,000/mm3), adequate liver function (SGPT less than or equal to 3 times upper limit normal and alkaline phosphatase less than or equal to 2 times upper limit normal, total bilirubin less than or equal to 1.5mg/dl, Patients with high bilirubin levels related to known diagnosis of benign hyperbilirubinemia (Gilbert s syndrome) will be eligible ., and adequate renal function (BUN less than or equal to 1.5 times institutional normal and Creatinine < 1.5 mg/dl) prior to registration. These tests must be performed within 14 days prior to registration.
- Patients must have shown unequivocal evidence for tumor progression as determined by an MRI scan done prior to study entry which will be reviewed by the treating physician to confirm and document recurrence.
- Patients with prior therapy that included interstitial brachytherapy or stereotactic radiosurgery must have confirmation of true progressive disease rather than radiation necrosis using the local institutional standards for such determination including advanced imaging or surgery.
- The baseline on-study MRI scan should be performed within 14 days (+ 3 working days) prior to registration but before starting treatment and on a steroid dose that has been stable or decreasing for at least 5 days. If the steroid dose is increased between the date of imaging and registration (or at that time), a new baseline MRI is required. The same type of scan, i.e., MRI must be used throughout the period of protocol treatment for tumor measurement.
- Patients having undergone recent resection of recurrent or progressive tumor will be eligible as long as all of the following conditions apply:
- At least 4 weeks (28 days ) have elapsed from the date of surgery and the patients have recovered from the effects of surgery.
- Evaluable or measureable disease following resection of recurrent Malignant Glioma is not mandated for eligibility into the study.
- To best assess the extent of residual disease post-operatively, a MRI should be done no later than 96 hours in the immediate post-operative period or at least 4 weeks post-operatively, within 14 days prior to registration. If the 96-hour scan is more than 14 days before registration, the scan needs to be repeated. If the steroid dose is increased between the date of imaging and registration, a new baseline MRI is required on a stable steroid dosage for at least 5 days.
- Patients must have failed prior radiation therapy and must have an interval of greater than or equal to 12 weeks (84 days) from the completion of radiation therapy to study entry except if there is unequivocal evidence for tumor recurrence (such as histological confirmation or advanced imaging data such as PET scan) in which case at least 4 weeks (28 days) from completion of radiation therapy will suffice.
- Patients with prior therapy that included interstitial brachytherapy or stereotactic radiosurgery must have confirmation of true progressive disease rather than radiation necrosis based upon either PET or Thallium scanning, MR spectroscopy or surgical/pathological documentation of disease.
- Women of childbearing potential must have a negative B-HCG pregnancy test documented within 14 days prior to registration. Women of childbearing potential must not be pregnant, must not be breast-feeding, and must practice adequate contraception for the duration of the study, and for 30 days after the last dose of study medication. Patients must not be pregnant because animal studies show that bevacizumab and Vorinostat are teratogenic.
- Male patients on treatment with Vorinostat must agree to use an adequate method of contraception for the duration of the study, and for 30 days after the last dose of study medication.
- Patient must be able to tolerate the procedures required in this study including periodic blood sampling, study related assessments, and management at the treating institution for the duration of the study.
- Patients receiving treatment with any antiepileptic medications except Valproic acid (because of its HDAC inhibitory activity) can be included in the study. Vorinostat is not metabolized by Cytochrome P450 3A4 (CYP 3A4); however, Vorinostat may potentially suppress CYP 3A4 activity. Therefore, patients should preferably be treated with nonenzyme inducing anti-epileptic medications although this is not mandatory. If enzyme inducing antiepileptic drugs are used, monitoring of these drug levels should be considered, as considered clinically appropriate by the treating physician.
- For the Phase II portion of the study, patients may have had treatment for no more than 2 prior relapses. There is no limit to the number of relapses for the phase I portion of the study provided the functional status and other eligibility criteria for enrollment are met. Relapse is defined as progression following initial therapy (i.e. radiation+/- chemo if that was used as initial therapy). The intent therefore is that patients had no more than 3 prior therapies (initial and treatment for 2 relapses). If the patient had a surgical resection for relapsed disease and no anti-cancer therapy was instituted for up to 12 weeks, and the patient undergoes another surgical resection, this is considered as 1 relapse. For patients who had prior therapy for a low-grade glioma, the surgical diagnosis of a high-grade glioma will be considered the first relapse

Read the detailed description
Background
- Glioblastoma (GBM) is the most common primary brain tumor. With optimal treatment, consisting of focal radiotherapy with concurrent chemotherapy, followed by adjuvant chemotherapy, median survival is 14.6 months. Most patients have evidence of tumor progression within one year of diagnosis despite treatment. At progression, treatment options are limited and mostly ineffective.
- Given the importance of angiogenesis in GBM, anti-angiogenic therapy is a promising strategy in recurrent GBM. Bevacizumab, the first angiogenesis inhibitor approved against cancer by FDA based on improved survival of advanced colon cancer patient, has recently been studied in the GBM.
- The present study aims to determine the potential of vorinostat, an HDAC inhibitor plus bevacizumab, versus bevacizumab alone, in an attempt to increase the anti-angiogenic effects of VEGF by blocking the evasive resistance by combination with vorinostat and to also not only provide the potential of the independent effects of both agents but also the potential for synergy.
Objectives
- To determine the maximum tolerated dose (MTD) of vorinostat plus bevacizumab in adult patients with malignant glioma.
- To determine the efficacy of vorinostat plus bevacizumab versus bevacizumab alone in patients with recurrent WHO grade IV glioma (glioblastoma and gliosarcoma) as determined by progression free survival (PFS) using an adaptive randomization phase II trial design.
Eligibility
- Patients must have histologically proven glioblastoma, gliosarcoma or anaplastic glioma to be eligible for the Phase I component of this protocol. Anaplastic gliomas include anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), anaplastic mixed oligoastrocytoma (AMO), or 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 malignant glioma is made. Only patients with histologically proven or imaging proven recurrent glioblastoma or gliosarcoma will be eligible for the Phase II component.
- Patients must have shown unequivocal evidence for tumor progression as determined by an MRI scan done prior to study entry which will be reviewed by the treating physician to confirm and document recurrence.
- No prior treatment with bevacizumab or Vorinostat
Design
The phase I component will assess the MTD of Vorinostat in combination with Bevacizumab. A conventional phase I design will be used and the MTD will be selected using a 3+3 accrual design at each dose level until MTD is determined. A maximum of 18 patients will be recruited to this component of the study.
The phase II component of the trial compares Bevacizumab to Vorinostat+ Bevacizumab in patients with recurrent GBM. The primary outcome is progression free survival. Patients will be randomized between the two arms using a Bayesian adaptive algorithm. Patients will be randomized fairly between the two arms at the start of the trial (for the first 20 patients). Thereafter, as the trial progresses and data accrue, the randomization will become unbalanced in favor of the treatment that, on average, has better results in terms of failure time. Therefore, each successive patient is more likely to receive the treatment with better results, on average. A minimum of 20 and a maximum of 90 patients will be accrued.

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression Free Survival (PFS) at 6 Months
PFS is time measured in months to disease progression as assessed at six months from participant registration. Assessments continue every 8 weeks up to 28 days after last dose (follow-up), anticipated trial length one year.
Participants must be assessed at least 4 weeks after surgery to begin treatment in the adaptive randomized Phase 2 portion of the trial. PFS in participants in the surgical arm determined from the date of randomization to the treatment arms and not from the date of registration in the trial.
Study outcome measure period ended June 2015.
Measured: Baseline until disease progression or death due to any cause, up to six months
Maximum Tolerated Dose (MTD) of Oral Vorinostat Used With Bevacizumab
MTD defined as the dose level at which 1/6 patients experience dose limiting toxicity (DLT), using conventional Phase I design where the MTD was selected using a 3+3 accrual design at each dose level until MTD was determined. Toxicities will be graded according to the Common Terminology Criteria for Adverse events (CTCAE) Version 4.0.
Measured: 28 day, cycle 1
Secondary outcomes (9)
Time to Progression (TTP)
Progression defined by the Modified MacDonald criteria is 25% increase in the sum of products, of all measurable lesions over smallest sum observed (over baseline if no decrease) using the same techniques as baseline, OR clear worsening of any evaluable disease, OR appearance of any lesion/site, OR failure to return for evaluation due to health or deteriorating condition (unless clearly unrelated to this cancer).
Measured: 3, 6, and 12 months from patient registration
Overall Survival (OS)
OS was computed using the number of months from the date of randomization to the date of death, up to 30 months. Participants still alive were censored at the last follow-up date.
Measured: up to 30 months.
Effects of Bevacizumab With and Without Vorinostat Upon Biomarkers of Angiogenesis Vascular Endothelial Growth Factor (VEGF), Placental Growth Factor (PIGF), and Basic Fibroblast Growth Factor (bFGF)
About 5cc of blood was collected to measure plasma angiogenic proteins vascular endothelial growth factor (VEGF), placental growth factor (PIGF), and basic fibroblast growth factor (bFGF) by enzyme-linked immunosorbent assay (ELISA).
Measured: Baseline before treatment, Cycle 1 Day 2, day 15 (pre-infusion and post-infusion), Cycle 2 (pre-infusion)
Effects of Bevacizumab With and Without Vorinostat Upon Biomarkers of Angiogenesis Stromal Cell-derived Factor α (SDF1α), and Angiopoietin 1 (Ang 1) and 2 (Ang 2) by Enzyme-linked Immunosorbent Assay (ELISA)
About 5cc of blood was collected to measure plasma angiogenic proteins stromal cell-derived factor α (SDF1α), angiopoietin 1 and 2 by enzyme-linked immunosorbent assay (ELISA).
Measured: Baseline before treatment, Cycle 1 Day 2, day 15 (pre-infusion and post-infusion), Cycle 2 (pre-infusion)
Percentage of Patients Rating Their Symptoms to be 7 or Greater on a 0-10 Scale Using the Mean Severity of the MD Anderson Symptom Inventory-Brain Tumor Module (MDSAI-BT) Self Reporting Tool
Percentage of patients rating their symptoms to be 7 or greater on a 0-10 scale using the MD Anderson Symptom Inventory-Brain Tumor Module (MDASI-BT) Self Reporting Tool. Zero is "not present" and 10 is "as bad as you can imagine. All patients with at least one valid questionnaire will be included in the analyses. Differences of at least 2 points will be classified as the minimum clinically meaningful change in the symptom severity and symptom interference measures.
Measured: Baseline, week 4, week 8, and end of therapy, approximately week 52 (cycle 12)
Mean Symptom Severity Using the MD Anderson Symptom Inventory-Brain Tumor Module (MDASI-BT) Self Reporting Tool
Overall mean severity of 22 symptoms. Symptoms are rated 0-10, zero is "not present" and 10 is "as bad as you can imagine". All patients with at least one valid questionnaire will be included in the analyses.
Measured: Baseline, week 4 (cycle 2), week 8 (cycle 4), and end of therapy, approximately week 52 (cycle 12)
Mean Symptom Interference at the Time of Clinical Evaluation
Overall mean interference severity of 6 interference items. Interference is rated 0-10, zero is "did not interfere" and 10 is "as bad as you can imagine". All patients with at least one valid questionnaire will be included in the analyses.
Measured: Baseline, (cycle 2), week 8 (cycle 4), and end of therapy, approximately week 52 (cycle 12)
Radiological Response
Magnetic resonance imaging (MRI) and contrast-enhanced (CE) MRI was used to evaluate tumor response. Response is defined by the Modified MacDonald criteria. Complete Response (CR) is complete disappearance of all measurable and evaluable disease. Partial response (PR) is greater than or equal to 50% decrease under baseline in the sum of products of perpendicular diameters of all measurable lesions. Partial Response, Non-Measurable (PRNM) is not applicable. Stable/No Response does not qualify for CR, PR or progression. Progression is 25% increase in the sum of products, of all measurable lesions over smallest sum observed (over baseline if no decrease) using the same techniques as baseline, OR clear worsening of any evaluable disease, OR appearance of any lesion/site, OR failure to return for evaluation due to health or deteriorating condition (unless clearly unrelated to this cancer).
Measured: End of therapy, approximately
Number of Participants With Serious and Non-Serious Adverse Events
Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
Measured: Phase I adverse events collected within 4 week (28 day) cycle. Phase II evaluated for adverse events after each cycle for first 2 cycles and subsequently after each 2 cycles of treatment prior to initiating the next cycle.

Primary outcome
Progression Free Survival (PFS) at 6 Months
Time frame: Baseline until disease progression or death due to any cause, up to six months
PFS is time measured in months to disease progression as assessed at six months from participant registration. Assessments continue every 8 weeks up to 28 days after last dose (follow-up), anticipated trial length one year. Participants must be assessed at least 4 weeks after surgery to begin treatment in the adaptive randomized Phase 2 portion of the trial. PFS in participants in the surgical arm determined from the date of randomization to the treatment arms and not from the date of registration in the trial. Study outcome measure period ended June 2015.
Maximum Tolerated Dose (MTD) of Oral Vorinostat Used With Bevacizumab
Time frame: 28 day, cycle 1
MTD defined as the dose level at which 1/6 patients experience dose limiting toxicity (DLT), using conventional Phase I design where the MTD was selected using a 3+3 accrual design at each dose level until MTD was determined. Toxicities will be graded according to the Common Terminology Criteria for Adverse events (CTCAE) Version 4.0.
9 secondary outcomes
Time to Progression (TTP)
Time frame: 3, 6, and 12 months from patient registration
Overall Survival (OS)
Time frame: up to 30 months.
Effects of Bevacizumab With and Without Vorinostat Upon Biomarkers of Angiogenesis Vascular Endothelial Growth Factor (VEGF), Placental Growth Factor (PIGF), and Basic Fibroblast Growth Factor (bFGF)
Time frame: Baseline before treatment, Cycle 1 Day 2, day 15 (pre-infusion and post-infusion), Cycle 2 (pre-infusion)
Effects of Bevacizumab With and Without Vorinostat Upon Biomarkers of Angiogenesis Stromal Cell-derived Factor α (SDF1α), and Angiopoietin 1 (Ang 1) and 2 (Ang 2) by Enzyme-linked Immunosorbent Assay (ELISA)
Time frame: Baseline before treatment, Cycle 1 Day 2, day 15 (pre-infusion and post-infusion), Cycle 2 (pre-infusion)
Percentage of Patients Rating Their Symptoms to be 7 or Greater on a 0-10 Scale Using the Mean Severity of the MD Anderson Symptom Inventory-Brain Tumor Module (MDSAI-BT) Self Reporting Tool
Time frame: Baseline, week 4, week 8, and end of therapy, approximately week 52 (cycle 12)
Mean Symptom Severity Using the MD Anderson Symptom Inventory-Brain Tumor Module (MDASI-BT) Self Reporting Tool
Time frame: Baseline, week 4 (cycle 2), week 8 (cycle 4), and end of therapy, approximately week 52 (cycle 12)

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing vorinostat and bevacizumab in people with Malignant Glioma and Recurrent Glioblastoma, run by National Cancer Institute (NCI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 29 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 31 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Sep 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression Free Survival (PFS) at 6 Months (time frame: Baseline until disease progression or death due to any cause, up to six months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2018.
