简要总结
This phase II/III trial tests how well adding mycophenolate mofetil, to the usual treatment with intensity-modulated radiation therapy and temozolomide works for the treatment of glioblastoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Mycophenolate mofetil blocks enzyme activity which can disrupt tumor activity and may make the tumor more sensitive to radiation and/or temozolomide. Intensity modulated radiation therapy is a type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy reduces the damage to healthy tissue near the tumor. Temozolomide is a chemotherapy drug and in a class of medications called alkylating agents. It damages the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. Giving mycophenolate mofetil with intensity-modulated radiation therapy and temozolomide may be more effective than intensity-modulated radiation therapy and temozolomide alone for the treatment of advanced glioblastoma.
详细描述
The primary and secondary objectives of the study:
PRIMARY OBJECTIVE:
I. To compare the overall survival (OS) (phase III) and progression-free survival (PFS) (phase II) between the experimental arm (mycophenolate mofetil [MMF] + standard of care [SOC]) and the control arm (SOC).
SECONDARY OBJECTIVES:
I. To compare the proportion of patients with an objective tumor response (ORR), measured with Response Assessment in Neuro-Oncology (RANO) 2.0 criteria, between the two treatment arms.

- •Patient is a candidate for first-line standard of care chemoradiation per treating physician(s)
- •No prior treatment for glioblastoma other than resection (i.e. prior chemotherapy, radiation therapy, or other therapies such as laser ablation are not allowed)
- •Prior biopsy and/or resection of glioblastoma must be completed at least 14 days prior to registration with adequate wound healing
- •Age ≥ 18 years
- •Karnofsky performance status (KPS) ≥ 60
- •Absolute neutrophil count (ANC) ≥ 1,500/mm^3
- •Platelet count ≥ 100,000 cells/mm^3
- •Hemoglobin (Hg) ≥ 9.0 g/dL

- •Bilirubin ≤ 1.5 x upper limit of normal (ULN)
- •Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤ 3.0 x ULN
- •Not pregnant and not nursing, because this study involves an agent that has known genotoxic, mutagenic and teratogenic effects.
- •Therefore, for women of childbearing potential only, a negative pregnancy test done ≤ 14 days prior to registration is required.
- •Women and men of reproductive potential must agree to use a highly effective method of birth control throughout their participation in this study and for at least 6 weeks (women) or 90 days (men) after last dose of treatment. Reproductive status and discussions about birth control measures should be documented in the patient's record. Appropriate methods of birth control include, but are not limited to: abstinence, oral contraceptives, implantable hormonal contraceptives or double barrier method (diaphragm plus condom)
- •Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
- •HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
- •For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
- •Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
- •No known history of allergic reaction or hypersensitivity to mycophenolate mofetil (MMF), mycophenolic acid (MPA), or any component of the drug product

- •No known medical condition causing an inability to swallow oral formulations of agents

- •No grade 4 lymphopenia (if absolute lymphocyte count [ALC] < 0.5, then patient must be on prophylaxis for Pneumocystis jirovecii)
- •No known history of organ transplantation
- •No known hypoxanthine-guanine phosphoribosyl-transferase deficiency
- •No known serious intercurrent illness that limits participation in the trial
- •No known immunosuppressive condition from autoimmune disease, immune deficiency syndrome, or chronic immunosuppressive therapy
- •Patient must be able to undergo MRI brain with and without contrast
- •No known phenylketonuria
- •No known medical contraindication for mycophenolate mofetil (MMF) per treating physician(s)
- •Patients on steroids must be on stable or decreasing dose within 7 days of registration (no more than 8 mg dexamethasone/day or equivalent)
