Brief Summary:
It has been shown that bevacizumab has significant anti-tumor activity in patients with recurrent glioblastoma multiforme. Vorinostat has modest anti-tumor activity against malignant glioma and can enhance the action of both chemotherapy and anti-angiogenics. Patients will be treated with a combination of bevacizumab and vorinostat.

Condition or disease Intervention/treatment Phase
Recurrent Glioblastoma Multiforme Malignant Glioma Adult Brain Tumor Drug: Vorinostat Drug: Bevacizumab Phase 2

Detailed Description:
There is no effective therapy for patients with recurrent glioblastoma multiforme (GBM) hence such patients remain a major unmet need in oncology. The investigators have recently demonstrated that bevacizumab (BV), a humanized monoclonal antibody against vascular endothelial growth factor, has significant anti-tumor activity among recurrent glioblastoma multiforme patients. Vorinostat has modest anti-tumor activity against malignant glioma and can potentiate the action of both chemotherapy and anti-angiogenics. The current study is designed to evaluate the anti-tumor activity of vorinostat when combined with BV among recurrent glioblastoma multiforme patients.

Primary Outcome Measures :
  1. Six-month Progression-free Survival (PFS6) [ Time Frame: 6 months ]
    The percentage of participants alive and progression-free at 6 months after the start of study treatment will be determined. Based on Response Assessment in Neuro-Oncology (RANO) criteria, progression is defined as a ≥ 25% increase in sum of the products of perpendicular diameters of enhancing lesions; significant increase in T2/FLAIR; any new lesion; clear clinical deterioration not attributable to other causes apart from the tumor; failure to return for evaluation as a result of death or deteriorating condition; or clear progression of non-measurable disease. PFS6 will be calculated from the date study treatment started until the date of progression or death, or the date of last follow-up if participants are alive without progression. Kaplan-Meier methods will be used to estimate survival.

Secondary Outcome Measures :
  1. Radiographic Response [ Time Frame: 3 Years ]
    The percentage of participants with a complete or partial response as determined by modified Response Assessment in Neuro-Oncology (RANO) criteria will be determined. Complete Response (CR) is defined as complete disappearance on MR/CT of all enhancing tumor and mass effect, off all corticosteroids (or receiving only adrenal replacement doses) and accompanied by a stable or improving neurologic examination. Partial Response (PR) is defined as greater than or equal to 50% reduction in tumor size on MR/CT by bi-dimensional measurement, on a stable or decreasing dose of corticosteroids and accompanied by a stable or improving neurologic examination. Tumor assessments are done at baseline and the end of every second cycle (every 8 weeks) thereafter.

  2. Percentage of Participants Who Experience Grade 3 or Greater, Treatment Related, Non-hematologic Toxicities. [ Time Frame: 2.7 Years ]
    The percentage of participants who experience grade 3 or greater, treatment-related, non-hematologic toxicities will be calculated.

  3. Median Progression-free Survival (PFS) [ Time Frame: 3 Years ]
    Progression-free survival is defined as the time in months from the start of protocol treatment until the date of progression or death if death occurred before progression. If the participant is alive and progression-free, PFS will be censored at the date of last follow-up. Kaplan-Meier methods will be used to estimate progression-free survival.

  4. Median Overall Survival (OS) [ Time Frame: 3 Years ]
    Overall survival is defined as the time in months from the start of protocol treatment until the date of death, or the date of last follow-up if alive. Kaplan-Meier methods will be used to estimate overall survival.

Ages Eligible for Study:   18 Years to 120 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age > 18 years.
  • 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 is biopsy-proven tumor progression
  • An interval of at least 4 weeks from prior chemotherapy [6 weeks for nitrosoureas, 1 week for daily administered chemotherapy (metronomic dosing)] or investigational agent unless the patient has recovered from all anticipated toxicities associated with that therapy.
  • Eastern Cooperative Oncology Group (ECOG) 0-1.
