Omental Tissue Autograft in Human Recurrent Glioblastoma Multiforme (rGBM)

Prior treatment

• Subject intends to undergo treatment with the Gliadel® wafer at the time of this surgery.
• Subject has had prior abdominal surgery that in the opinion of the general surgeon makes removal of omentum more risky or inadequate.

Other illness

• Subject has an active infection requiring treatment.
• Subject has radiographic evidence of multi-focal disease or leptomeningeal dissemination.
• Subject has a history of other malignancy, unless the patient has been disease- free for at least 5 years. Adequately treated basal cell carcinoma or squamous cell skin cancer is acceptable regardless of time, as well as localized prostate carcinoma or cervical carcinoma in situ after curative treatment
• Subject has a known positive test for human immunodeficiency virus infection, or active hepatitis B or hepatitis C infection.
• Subject has a history or evidence of any other clinically significant disorder, condition or disease that would pose a risk to subject safety or interfere with the study evaluation, procedures or completion.
• Subject has severe renal insufficiency rendering gadolinium MRI contraindicated.

Other

• Subject, if female, is pregnant or is breast feeding.
• Subject intends to participate in another clinical trial.
• Subject who are unable to have an MRI scan for any reason.

• Subject is a male or female 18 years of age or older.
• Subject is undergoing planned resection of known or suspected GBM.
• Subject has a Karnofsky Performance Status (KPS) 70% or greater.
• Subject has a life expectancy of at least 6 months, in the opinion of the Investigator.
• Based on the pre-operative evaluation by neurosurgeon, the subject is a candidate for ≥ 80% resection of enhancing region.
• Subject must be able to undergo MRI evaluation.
• Subject meets the following laboratory criteria:
  • White blood count ≥ 3,000/μL
  • Absolute neutrophil count ≥ 1,500/μL
  • Platelets ≥ 100,000/μL
  • Hemoglobin \> 10.0 g/dL (transfusion and/or ESA allowed)
  • Total bilirubin and alkaline phosphatase ≤ 2x institutional upper limit of normal (ULN)
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \< 3 x ULN
  • Blood urea nitrogen (BUN) and creatinine \< 1.5 x ULN
• Females of reproductive potential must have a negative serum pregnancy test and be willing to use an acceptable method of birth control.
• Able to understand and willing to sign an institutional review board (IRB)- approved written informed consent document
• Subject has a histologically confirmed (frozen section) diagnosis of recurrent WHO Grade IV glioblastoma multiforme (GBM).
• Omental graft is technically feasible.
