Phase 1 Trial of D2C7-IT in Combination With 2141-V11 for Recurrent Malignant Glioma

Summary

This is a phase 1 study of an anti-CD40 monoclonal antibody (2141-V11) in combination with D2C7-IT for patients with recurrent World Health Organization (WHO) grade III or IV malignant glioma at the Preston Robert Tisch Brain Tumor Center (PRTBTC) at Duke.

Eligibility

Inclusion Criteria:

1. Study population:

   1. Subgroup #2: Histopathologically confirmed recurrent supratentorial WHO grade 3 or 4 malignant glioma (high grade glioma with molecular features of glioblastoma will be eligible under WHO grade 4 malignant glioma)
   2. Subgroup #3: Histopathologically confirmed recurrent supratentorial WHO grade 4 malignant glioma (high grade glioma with molecular features of glioblastoma will be eligible under WHO grade 4 malignant glioma) and found amenable for Tumor Monorail Device (TMD) implantation as per the treating neurosurgeon
2. 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 people who are post-menopausal or surgically sterile. Surgically sterile people are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal ligation or have had a vasectomy. 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 (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.
3. Age ≥ 18 years of age at the time of entry into the study
4. Karnofsky Performance Score (KPS) ≥ 70%
5. Hemoglobin ≥ 9 g/dl prior to biopsy
6. 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
7. Neutrophil count ≥ 1000 prior to biopsy
8. Creatinine ≤ 1.5 x normal range prior to biopsy
9. Total bilirubin ≤ 1.5 x ULN prior to biopsy (Exception: Participant has known or 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.)
10. AST/ALT ≤ 2.5 x ULN
11. Prothrombin and Partial Thromboplastin Times ≤ 1.2 x normal 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.
12. At the time of biopsy, prior to administration of D2C7-IT, the presence of recurrent tumor must be confirmed by histopathological analysis
13. 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
14. Able to undergo brain MRI with and without contrast

Exclusion Criteria:

1. Patients who are pregnant or breastfeeding/chestfeeding
2. Patients with an impending, life-threatening cerebral herniation syndrome, based on the assessment of the study neurosurgeons or their designate
3. Patients with severe, active co-morbidity, defined as follow:

   1. Patients with an active infection requiring intravenous treatment or having an unexplained febrile illness (Tmax \> 99.5°F/37.5°C)

   3. Patients with unstable or severe intercurrent medical conditions such as severe heart disease (New York Heart Association Class 3 or 4)
   4. Patients with known lung (forced expiratory volume in the first second of expiration (FEV1) \< 50%) disease or uncontrolled diabetes mellitus
   5. Patients with albumin allergy
4. Patients may not have received chemotherapy or bevacizumab ≤ 4 weeks \[except for nitrosourea (6 weeks), or metronomic dosed chemotherapy such as daily etoposide or cyclophosphamide (1 week)\] prior to starting the study drug unless patients have recovered from side effects of such therapy
5. Patients may not have received immunotherapy ≤ 4 weeks prior to starting the study drug unless patients have recovered from side effects of such therapy
6. Patients may not have received treatment with tumor treating fields (e.g., Optune) ≤ 1 week prior to starting the study drug
7. Patients may not be less than 12 weeks from radiation therapy, unless progressive disease outside of the radiation field or 2 progressive scans at least 4 weeks apart or histopathologic confirmation
8. Patients who have not completed all standard of care treatments, including surgical procedure and radiation therapy (Please note: For patients under 65 years old, standard radiation therapy is typically at least 59 Gy in 30 fractions over 6 weeks. For patients 65 years or older, standard RT is often reduced to a minimum 40 Gy in 15 fractions over 3 weeks.)

   1. If the MGMT promoter in their tumor is known to be unmethylated, patients are not mandated to have received chemotherapy prior to participating in this trial
   2. If the MGMT promoter in their tumor is known to be methylated or the MGMT promoter methylation status is unknown at time of screening, patients must have received at least one chemotherapy regimen prior to participating in this trial
