Acetazolamide Sodium and Temozolomide in Treating Adult Patients with Newly Diagnosed MGMT Promoter-Methylated IDH Wildtype Glioblastoma
- Histologically proven, newly diagnosed IDH wildtype GBM that has a methylated MGMT promoter as assessed by the standardized institutional analysis
- Patients are eligible if they had a prior low grade astrocytoma that was not previously treated, and there is subsequent histological evidence of a diagnosis of grade III or IV astrocytoma
- Patients are eligible if they are going to receive TMZ as part of the standard adjuvant treatment regimen following concomitant TMZ/radiation therapy (RT)
- Patients must have a Karnofsky performance >= 60%
- Absolute neutrophil count (ANC) >= 1.5 x 10^9/ L
- Platelets >= 100 x 10^9 / L
- Hemoglobin >= 8.0 g / dL
- Creatinine level within normal institutional limit, or creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine level above institutional normal
- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) < 2.5 X institutional upper limit of normal
- Total bilirubin =< 1.5 x upper limit of normal (ULN)
- International normalized ratio (INR) within 1.5 times ULN (or if receiving anticoagulant therapy an INR of =< 3.0 is allowed with concomitant increase in prothrombin time (PT) or an activated partial thromboplastin time (aPTT) =< 2.5 x control)
- Women of childbearing potential must have a negative pregnancy test within 30 days of registration
- Patients must have the ability to understand and the willingness to sign a written informed consent document
- Prior invasive malignancy that is not low-grade glioma (except non-melanomatous skin cancer or carcinoma in situ of the cervix) unless the patient has been disease free and off therapy for that disease for a minimum of 3 years
- Active systemic infection requiring treatment, including any human immunodeficiency virus (HIV) infection or toxoplasmosis
- Other severe acute or chronic medical or psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation or study drug administration (e.g. acidosis, adrenocortical insufficiency, cirrhosis)
- Systemic corticosteroid therapy, > 8 mg of dexamethasone daily (or equivalent) at study enrollment
- Pregnant women are excluded from this study, where pregnancy is confirmed by a positive serum beta-human chorionic gonadotropin (hCG) laboratory test; breast-feeding should be discontinued
- Hypersensitivity to acetazolamide or sulfonamides
I. To determine the safety, tolerability and adverse event profile of adding acetazolamide sodium (acetazolamide) to temozolomide in patients with newly diagnosed IDH wildtype glioblastoma.
I. To describe the objective response rate (ORR), progression free survival (PFS) and overall survival (OS).
II. To determine the feasibility of the cooperative interaction between BrainUp, the University of Chicago Medical Center, NorthShore University HealthSystem, Northwestern Memorial Hospital, Northwestern Medicine Central DuPage Hospital, University of Illinois Chicago Medical Center, Rush University Medical Center, Illinois Cancer Care (Peoria) and Decatur Memorial Hospital.
III. To evaluate Bcl-3 expression level within each tumor and to preliminarily examine the ability of Bcl-3 to predict response to temozolomide (TMZ) and the efficacy of adding acetazolamide sodium (ACZ).
OUTLINE: This is a dose-escalation study of acetazolamide sodium.
CONCOMITANT PHASE: Patients receive temozolomide orally (PO) daily on days 1-42 while undergoing focal radiotherapy.
MAINTENANCE PHASE: Patients receive temozolomide PO daily on days 1-5 and acetazolamide sodium PO twice daily (BID) on days 1-21. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 2 months.
