Brief Summary:
This is a phase 1 study of atezolizumab in combination with D2C7-IT, a dual-specific monoclonal antibody (mAB) with a high affinity for both EGFRwt- and EGFRvIII-expressing cells, in patients with recurrent World Health Organization (WHO) grade IV malignant glioma at the Preston Robert Tisch Brain Tumor Center (PRTBTC) at Duke.

Condition or disease Intervention/treatment Phase
Malignant Glioma Drug: D2C7-IT (6920 ng/mL via convection-enhanced delivery) Drug: Atezolizumab (1200 mg every three weeks) Phase 1

Detailed Description:

Approximately eighteen patients with recurrent WHO grade IV malignant glioma will receive atezolizumab and D2C7-IT to determine the impact of the combination of D2C7-IT and atezolizumab on safety. D2C7-IT will be delivered intratumorally by Convection Enhanced Delivery (CED) using an intracerebral catheter placed within the enhancing portion of the tumor.

Atezolizumab will be administered according to the FDA-approved dosing schedule of 1200 mg intravenously every 3 weeks, beginning ~2 weeks after the D2C7-IT infusion.

Toxicity will be carefully monitored for each patient while they are on study for at least a year after D2C7-IT treatment or for at least 30 days after the final dose of atezolizumab if the patient continues atezolizumab on-study for longer than a year post-D2C7-IT. Of particular interest will be the incidence of adverse events that occur during the first 28 days after D2C7-IT treatment and the inflammatory events that occur during the first year after D2C7-IT treatment.

The most common risks associated with D2C7-IT are effects related to tumor necrosis, neurologic changes (including changes in function, new or increased seizures, swelling of the brain, and injury to blood vessels), effects related to catheter placement or removal, and effects related to fluid infusion into the brain. The most common risks associated with atezolizumab are fatigue, decreased appetite, diarrhea, and nausea. Because atezolizumab works with the immune system, it can cause the immune system to attack normal organs or tissue and affect how they work.

Primary Outcome Measures :
  1. Proportion of patients with an unacceptable adverse event [ Time Frame: 2 years ]
    An unacceptable adverse event includes any Grade 3 or any Grade 4 toxicity that is not reversible within 2 weeks, any life-threatening event, or any treatment-related death. Also included are any grade 2 or higher serious autoimmune toxicities, particularly those affecting vital organs (e.g. cardiac, renal, CNS) if it occurs within 2 weeks of any protocol treatment.

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

Inclusion Criteria:

  • Patients must have a recurrent supratentorial WHO grade IV malignant glioma based on imaging studies
  • Prior histopathology confirmed recurrent supratentorial WHO grade IV malignant glioma
  • Patient or partner(s) meets one of the following criteria:

    1. Non-childbearing potential (i.e. not sexually active, physiologically incapable of becoming pregnant, including any female who is post-menopausal or surgically sterile, or any male who has had a vasectomy). Surgically sterile females are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal l ligation. Postmenopausal for purposes of this study is defined as 1 year without menses; or,
    2. Childbearing potential and agrees to use one of the following methods of birth control: approved hormonal contraceptives that do not contain estrogen (e.g., birth control pills, patches, implants, or infusions), an intrauterine device, or a barrier method of contraception (e.g., a condom or diaphragm) used with spermicide.
  • Age ≥ 18 years of age at the time of entry into the study
  • Karnofsky Performance Score (KPS) ≥ 70%
  • Hemoglobin ≥ 9 g/dl prior to biopsy
  • Platelet count ≥ 100,000/µl unsupported is necessary for eligibility on the study; however, because of risks of intracranial hemorrhage with catheter placement, platelet count ≥ 125,000/µl is required for the patient to undergo biopsy and catheter insertion, which can be attained with the help of platelet transfusion
  • Neutrophil count ≥ 1000 cells/mm3 prior to biopsy
  • Creatinine ≤ 1.5 x upper limit of normal (ULN) range prior to biopsy
  • Total bilirubin ≤ 1.5 x ULN prior to biopsy, s (Exception: Patient has known Gilbert's Syndrome or patient has suspected Gilbert's Syndrome, for which additional lab testing of direct and/or indirect bilirubin supports this diagnosis. In these instances, a total bilirubin of ≤ 3.0 x ULN is acceptable.)
  • AST (aspartate aminotransferase)/ALT (alanine aminotransferase) ≤ 2.5 x ULN prior to biopsy
  • Prothrombin and Partial Thromboplastin Times ≤ 1.2 x ULN prior to biopsy. Patients with prior history of thrombosis/embolism are allowed to be on anticoagulation, understanding that anticoagulation will be held in the perioperative period per the neurosurgical team's recommendations. Low molecular weight heparin (LMWH) is preferred. If a patient is on warfarin, the international normalized ratio (INR) is to be obtained and value should be below 2.0 prior to biopsy.
  • At the time of biopsy, prior to administration of D2C7-IT, the presence of recurrent tumor must be confirmed by histopathological analysis
  • A signed informed consent form approved by the Institutional Review Board (IRB) will be required for patient enrollment into the study. Patients must be able to read and understand the informed consent document and must sign the informed consent indicating that they are aware of the investigational nature of this study
