Korábbi kezelés

• Patients who are receiving any other investigational agents.
  • Exception: COVID-19 vaccine and treatment is allowed
• Patient who have a prior or concurrent malignancy that may interfere with study treatment or safety.
  • NOTE: 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. Per principal investigator (PI) discretion
• Patients requiring live vaccinations within 2 weeks of initiation of MMF and/or TMZ therapy. Consider completion of vaccination with live vaccines prior to starting immunosuppressive therapy, as indicated.
• Patients who have an uncontrolled intercurrent illness including, but not limited to any of the following, are not eligible:
  • Have uncontrolled epilepsy
  • Have an uncontrolled intercurrent illness
  • Concurrent malignancy (outside of glioblastoma) that requires tumor directed treatment
  • Known deficiency of hypoxanthine-guanin-phosphoribosyltransferase (HGPRT) deficiency, e.g. Lesch-Nyhan- oder Kelley-Seegmiller-Syndrome.
  • Known concurrent shingles, herpes, CMV (cytomegalovirus) infection
  • Known concurrent opportunistic fungal infection
  • Known concurrent or history of unexplained opportunistic infection
  • Known immunodeficiency that could lead to opportunistic infections
  • Psychiatric illness/social situations that would limit compliance with study requirements. Any other illness or condition that the treating investigator feels would interfere with study compliance or would compromise the patient's safety or study endpoints.
• Female patients who are pregnant or nursing. Pregnant women are excluded from this study because temozolomide is an alkylating agent with potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with temozolomide, breastfeeding should be discontinued if the mother is treated with temozolomide.
• Patients who require treatment with a therapy that is categorized as a "prohibited therapy" as listed in Section 4.10 of the protocol and who are unable to safety discontinue the prohibited therapy prior to the first dose of MMF or TMZ.

• Females of child-bearing potential (FOCBP) must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) from time of informed consent, for the duration of study participation, and for 3 months following completion of therapy.
