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.

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.

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.

Immunotoxins

Recurrent malignant glioma patients will receive D2C7-IT, delivered intratumorally by CED following confirmatory diagnostic biopsy.

D2C7-IT is a single-chain fragment variable (scFv) monoclonal antibody (Mab) fragment immunotoxin with high binding affinity for both EGFRwt- and EGFRvIII-expressing glioblastoma multiforme (GBM) cells.

This is a Phase I study to determine the maximum tolerated dose (MTD) and/or recommended phase II dose of D2C7-IT (D2C7 Immunotoxin) when delivered intratumorally by convection-enhanced delivery (CED) to recurrent World Health Organization (WHO) grade III and IV malignant glioma patients, and/or to determine what dose will be considered in a Phase II trial. Patients with recurrent WHO grade III and IV malignant glioma who meet eligibility criteria will be enrolled into the study. Immediately following the stereotactically-guided tumor biopsy conducted as standard of care, up to three additional core biopsies will be obtained for molecular genetic testing. After these biopsies are obtained, subjects will have up to 2 catheters inserted. If the biopsy indicates a proven diagnosis of recurrent malignant glioma (diagnosis results are typically received within 24-48 hours following biopsy), the investigators will proceed with the D2C7-IT infusion. If no tumor is identified, the catheters will be removed. A continuous intratumoral infusion of D2C7-IT will be administered over 72 hours while in the hospital.

This is a Phase I study to determine the maximum tolerated dose (MTD) of D2C7-IT, when delivered intratumorally by convection-enhanced delivery (CED) following confirmatory diagnostic biopsy in recurrent World Health Organization (WHO) grade III and IV malignant glioma patients, and/or to determine what dose will be considered in a phase II trial. The patient will remain in the hospital during the entire infusion. At the completion of the infusion, the catheters will be removed within 6 hours and a CT scan will be obtained after the catheters are pulled. The patient will be observed in hospital for a minimum of another 6 hours.

A two-stage continual reassessment method (CRM) design will be used to determine the MTD of D2C7-IT where the first stage involves dose escalation in successive patients until an initial dose-limiting toxicity (DLT) is observed. Cohorts of 2 patients will be accrued to this study within both stages of the trial. The first patient of each cohort will be observed through the completion of the D2C7-IT infusion, before additional patients in that cohort are treated. Once the optimal dose level of D2C7-IT is determined (dose escalation completed), a total of 27 recurrent patients with WHO grade IV malignant glioma patients will be treated at that dose level as a dose expansion cohort.

Following D2C7-IT infusion, subjects will be evaluated in clinic at 2 weeks for adverse events and followed at 4 and 8 weeks and every 8 weeks thereafter until 48 weeks.

Phase I Single-Center, Dose Escalation Study of D2C7-IT Administered Intratumorally Via Convection-Enhanced Delivery for Adult Patients With Recurrent Malignant Glioma

The MTD is the dose that results in an estimated DLT rate based upon the CRM model that is nearest to the target DLT rate of 0.25. DLTs include any ≥ Gr.3 non-hematologic toxicities, any ≥ Gr.3 neurological toxicities, and any ≥ Gr.3 hematologic toxicities that do not resolve to pre-treatment baseline or ≤ Gr.1 within 2 weeks or any toxicity that resolves within the 2 week period, but then recurs during that same 2 week period. Adverse events will be collected using Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

OS is defined at the time between administration of D2C7-IT and death. For patients alive, OS will be censored at the time of last follow-up. Kaplan-Meier methods will be used to estimate median OS and PFS.

Cox proportional hazards models will explore the relationship between EGFRvIII and EGFRwt expression as measured by immunohistochemistry (IHC), polymerase chain reactions (PCR), and fluorescence in situ hybridization (FISH) and PFS and OS.

Immunomodulating Agents

Single D2C7-IT intratumoral infusion (6920 ng/mL in 36 mL) over 72 hours followed by single 2141-V11 infusion (5 dose levels) over 7 hours followed by an injection of 2141-V11 in the cervical perilymphatic subcutaneous area ipsilateral to the tumor at week 2, radiation, and further injections of 2141-V11 in the cervical perilymphatic subcutaneous area ipsilateral to the tumor.

D2C7-IT will be dosed at 166,075 ng in 36 mL.

2141-V11 will be dosed at 3 mg in 3.5 mL for CED administration. 2141-V11 in the cervical perilymphatic subcutaneous area will be dosed at 2 mg.

The purpose of this research study is to determine the safety and efficacy of administering a single intracerebral (within the brain) dose of investigational compounds called D2C7-immunotoxin (IT) and 2141-V11 in residual disease (within tumor margins) after surgery, followed by later repeated injections of 2141-V11 in the subcutaneous area (under the skin) around the lymph nodes of the head and neck for adults newly diagnosed with a type of cancerous brain tumor called glioblastoma. The word "investigational" means the study drugs are still being tested in research studies and are not approved by the U.S. Food and Drug Administration (FDA).

Within this study, approximately 50 study participants will receive a single infusion of D2C7-IT in the hospital, which is delivered to the tumor margins over 3 days through a catheter placed in the brain, followed by a single infusion of 2141-V11 delivered over 7 hours to the tumor margins through the same catheter. About 2 weeks after intratumoral infusion of D2C7-IT and 2141-V11, participants will have their first subcutaneous (under the skin) injection of 2141-V11 in the area around the lymph nodes of the head and neck on the same side as the tumor. About a week after this injection, participants will start standard radiation therapy (RT), which typically lasts either 3 weeks or 6 weeks depending upon age. Once RT is finished, participants will resume injections in the area around the lymph nodes of the head and neck on the same side as the tumor of 2141-V11 about 1 week later. They will have another injection about 3 weeks after finishing RT and then start a schedule of injections about every 3 weeks for up to a year.

There are risks to the study drugs that are described in this document. Some common risks related to D2C7-IT include: effects related to tumor cells dying (tumor necrosis), effects on normal brain tissue, effects related to catheter placement and removal, effects related to fluid infusion into the brain (intracerebral infusion), and reactions to the D2C7-IT being directly infused in your brain. Risks of 2141-V11 being directly infused in your brain and injected in the area around the lymph nodes of the head and neck could include: cytokine release syndrome (release of immune system cells called cytokines that can cause fever, chills, headache, muscle pain, itching, rash, chest tightness, palpitations, shortness of breath, low blood pressure, nausea, vomiting), swelling and redness in the neck area, overstimulation of your immune system such that it attacks other tissues in your body, elevated liver enzymes, and low platelets in the blood.
