Study Details

Study Description

Brief 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.

Condition or Disease	Intervention/Treatment	Phase
Glioma, Malignant	Drug: D2C7-IT Drug: 2141-V11	Phase 1

Detailed Description

Within this study, a maximum of 30 patients with recurrent WHO grade III and IV malignant glioma will receive D2C7-IT and 2141-V11 to determine the impact of the combination of D2C7-IT and 2141-V11 on safety. D2C7-IT and 2141-V11 will be delivered sequentially directly into the tumor by Convection Enhanced Delivery (CED) using an intracerebral catheter placed within the enhancing portion of the tumor. Based on phase 1 studies of D2C7-IT alone and D2C7-IT in combination with atezolizumab in adult patients with recurrent glioblastoma (GBM), the amount of D2C7-IT to be delivered will be 4613.2 ng/mL (36 mL). 2141-V11 will be dose escalated during the study to determine the maximum tolerated dose (MTD) when used in combination with D2C7-IT.

Outcome Measures

Primary Outcome Measures

Proportion of patients with dose-limiting toxicity (DLT) within each dose level [28 days after catheter removal]
DLTs are defined as any of the following events that are at least possibly, probably, or definitely attributable to study treatment (2141-V11 or the combination of D2C7-IT and 2141-V11) during dose escalation. As the optimal dose of D2C7-IT in monotherapy has been well established, only toxicity starting or increasing in grade at any time after the start of 2141-V11 will be considered for DLT definition.

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Histopathologically confirmed recurrent supratentorial WHO grade III or IV malignant glioma (high grade glioma with molecular features of glioblastoma will be eligible under WHO grade IV malignant glioma)
Patient or partner(s) meets one of the following criteria:

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 ligation. Postmenopausal for purposes of this study is defined as 1 year without menses.; or
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.

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 prior to biopsy
Creatinine ≤ 1.5 x normal range prior to biopsy
Total bilirubin ≤ 1.5 x upper limit of normal (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)
Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤ 2.5 x ULN
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.
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
Able to undergo brain MRI with and without contrast
