Arms Assigned Interventions
Experimental: VAL-083 Drug: VAL-083
The dosing regimen for patients will be VAL-083 (40 mg/m2) administered IV for 3 consecutive days at the beginning of every 21-day cycle. Patients will continue to receive VAL 083, for up to 12, 21-day treatment cycles or until they fulfill one of the criteria for study discontinuation. In patients who demonstrate response or stable disease and tolerate therapy, permission to continue treatment beyond 12 cycles will be considered, but will require consent of the Sponsor.

Detailed Description:

Recurrent glioblastoma (GBM) is characterized by a dismal prognosis, with a median overall survival of 6-9 months. While a standard of care is established for the initial treatment of GBM - radiation with concurrent and adjuvant temozolomide chemotherapy - management of recurrent disease remains suboptimal. Treatment options include repeat surgery, re-irradiation, or chemotherapy (including experimental targeted therapies, biologic agents, and immunotherapies). Only a minority of patients has response to these treatments, and the resultant benefits in progression-free and overall survival are on the order of weeks to months.

Prognosis and response to therapy are known to be better in patients with a methylated MGMT promoter gene. Epigenetic silencing of MGMT by promoter methylation is an important factor in predicting outcome for patients with GBM treated with temozolomide. Approximately 66% of GBM tumors are MGMT unmethylated (high expression of MGMT), which through a MGMT repair mechanism, confers resistance to temozolomide, the standard chemotherapy treatment of GBM.

VAL-083, Dianhydrogalactitol (DAG), unlike temozolomide, is demonstrated to be active independent of MGMT resistance mechanisms, in vitro. Thus, it may provide a treatment option for those patients that are considered likely to be poor responders to temozolomide.

This is a non-comparative, single arm, biomarker-driven study with VAL-083.


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

Inclusion Criteria:

  • Patient must willingly provide written consent after being informed of the procedure to be followed, the experimental nature of the therapy, alternatives, potential benefits, side effects, risks, and discomforts.
  • Patients must be ≥ 18 years old.
  • Patients must have histologically confirmed initial diagnosis of primary intracranial World Health Organization (WHO) Grade IV malignant glioma (glioblastoma, GBM), now recurrent. Patients with recurrent disease whose initial diagnostic pathology confirmed glioblastoma will not need re-biopsy. Alternately, patients with prior intracranial low-grade glioma or anaplastic glioma will be eligible, if histologic assessment demonstrates transformation to GBM (first diagnosis of secondary GBM).
  • Patients must have radiographic evidence of recurrent/progressive GBM after prior therapy (biopsy or resection and chemoradiation); 1st recurrence of GBM only, per Response Assessment in Neuro-Oncology Criteria (RANO) criteria. Histologically documented transformation from a lower grade gliomas will be considered first recurrence.
  • Patients must have confirmed GBM MGMT status (tumor must be MGMT promoter unmethylated) by central laboratory Clinical Laboratory Improvement Amendments (CLIA) certified testing at MD Anderson, prior to registration. If initial MGMT testing obtained at an outside institution, MGMT status must be centrally retested at MD Anderson.
  • Patients must have Karnofsky Performance Status (KPS) > 60%.
  • Patients must have been previously treated for GBM with radiation with concurrent and adjuvant temozolomide chemotherapy.
  • Adequate recovery from all recent surgery is required. At least 21-days must have elapsed from the time of any major surgery, including craniotomy/tumor resection. Patients must have recovered from all surgery-related toxicities to Grade 1 or less.
  • Patients must ≥ 12 weeks from radiotherapy, to minimize the potential for magnetic resonance imaging (MRI) changes related to treatment (pseudo progression) that might be misdiagnosed as true progression of disease, unless the patient fulfills criteria for early progressive disease by RANO.
  • Prior therapy with gamma knife or other focal high-dose radiation is allowed, but at least 2 weeks must have elapsed from the time of treatment, and the patient must have subsequent histologic documentation of recurrence, unless the recurrence is a new lesion outside the irradiated field.
  • Patients must be at least 4 weeks from last dose of chemotherapy.
  • Patients must be at least 4 weeks or 5 half-lives (whichever is shorter) from the last dose of prior investigational anti-cancer drugs.
  • Patients must have recovered from all treatment-related toxicities to Grade 1 or less.
  • If receiving corticosteroids, patients must be on a stable or decreasing dose of corticosteroids for ≥ 5 days prior to baseline MRI.
  • Patients must have a predicted life expectancy of at least 12 weeks.
  • Patients must have adequate bone marrow and organ function.
  • Patients must be willing and able to comply with scheduled visits, treatment plan, and laboratory tests and accessible for follow-up.
  • If the patient has been using the Optune™ device, it will be discontinued before initiating treatment with either study medication, and per inclusion criterion listed above, the patient must have recovered from all treatment-related toxicities to Grade 1 or less.
  • Pregnancy restrictions - Women of childbearing potential must have a negative B-HCG documented within 7 days prior to registration

Exclusion Criteria:

  • Within 12 weeks of chemoradiation unless the patient fulfills criteria for early progressive disease by RANO
  • Receipt of investigational agents within 5 half-lives of last dose of investigational agent
  • Concurrent use of other investigational agents or Optune™ device
  • Prior therapy with lomustine
  • Prior therapy with bevacizumab
  • Current history of neoplasm other than the entry diagnosis. Patients with previous cancers treated and cured with local therapy alone may be considered with approval of the PI
  • Evidence of leptomeningeal spread of disease
  • Need for urgent palliative intervention (e.g., impending herniation)
  • Severe, intercurrent illness including, but not limited to unstable systemic disease, including ongoing or active infection, uncontrolled hypertension, serious cardiac arrhythmia requiring medication, or psychiatric illness/social situations that would limit compliance with study requirements
  • Use of medications known to be strong inhibitors of CYP3A4 up to 14 days before Cycle 1 Day 1
  • Patients with a known sensitivity to any of the products to be administered during treatment
  • Patients unable to undergo MRI of the brain
  • Women who are pregnant or lactating. Women of childbearing potential must have a negative serum or urine pregnancy test performed within 7 days prior to start of treatment. Women of childbearing potential or men with partners of childbearing potential must use effective birth control measures during treatment.
