Marizomib for Recurrent Low-Grade and Anaplastic Supratentorial, Infratentorial, and Spinal Cord Ependymoma

Phase II Clinical Trial of Marizomib for Recurrent Low-Grade and Anaplastic Supratentorial, Infratentorial and Spinal Cord Ependymoma

Background:

Ependymomas are rare tumors that arise from the ependyma. That is a tissue of the central nervous system. They can develop in the brain or the spine. They are usually treated with surgery, radiation, and/or chemotherapy. Researchers want to see if the new drug marizomib can help people with a certain kind of ependymoma.

Objective:

To see if marizomib stops tumor growth and prolongs the time that the tumor is controlled.

Eligibility:

Adults age 18 and older who have been diagnosed with ependymomas and have already been treated with standard therapies

Design:

Participants will be screened with the following tests or recent results from similar tests:

• Medical history
• Physical exam
• Neurological assessment
• Electrocardiogram (EKG) to evaluate the heart
• Review of symptoms and ability to perform normal activities
• Computed tomographic scan (CT) or magnetic resonance imaging (MRI) to produce an image of the brain or spine.
• Blood and urine tests
• Tests of tumor samples. Participants may have to have new tumor samples taken.

Participants will get the study drug in cycles. Each cycle is 4 weeks. Participants will have up to 24 cycles.

Participants will get the study drug through a small plastic tube in a vein on days 1, 8, and 15 of each cycle.

During each cycle, some screening tests will be repeated.

Participants will answer questions about their general well-being and functioning.

About 4 5 weeks after finishing the study drug, participants will have a follow-up visit. They will answer questions about their health, get a physical and a neurological exam, and have blood tests. They may have an MRI or CT scan.

Study Overview

• Status: Terminated
• Conditions: Ependymoma; Anaplastic Ependymoma; Ependymomas
• Intervention / Treatment: Drug: Marizomib

Detailed Description

Background:

• Ependymomas are rare primary brain tumors arising from radial glial stem cells. They comprise 5.2% of all pediatric primary brain tumors and 1.9% of all adult primary brain tumors.
• The standard therapy for newly diagnosed ependymoma is gross total resection followed by radiation therapy. For anaplastic ependymoma, recurrence rate is high with a median progression free survival (PFS) of 2.3 years.
• There are limited chemotherapy options for recurrent ependymomas, which have already been irradiated. Therefore, there is an unmet need to target novel pathways for treatment of ependymomas.
• About 70% of supratentorial ependymomas have a characteristic signature C11 orf95-V-Rel Avian Reticuloendotheliosis Viral Oncogene Homolog A (RELA) fusion which drives tumorigenesis in ependymomas by activating the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-KB) transcription pathway.
• Marizomib is a second-generation irreversible proteasome inhibitor which penetrates across the blood-brain-barrier (BBB). It inhibits the activity of 20S proteasome in glioma cells, activates caspases, builds up reactive oxygen species and thus induces apoptosis. Marizomib blocks the NF-pathway by proteasome inhibition. Thus, it may have an additional targeted therapeutic effect in the RELA-fusion molecular subgroup of ependymomas.

Objective:

-To evaluate the efficacy of treatment with marizomib in RELA-fusion recurrent ependymoma and non RELA-fusion recurrent ependymoma as measured by progression-free survival at 6 months (PFS6).

Eligibility:

• Histologically proven intra-cranial or spinal ependymoma.
• Radiographic evidence of tumor progression
• Patients must be greater than or equal to 18 years old.

Patients must have had prior radiotherapy.

Design:

• This is a phase II study to determine the efficacy of marizomib in recurrent ependymoma.
• A novel 2-stage sequential design will be employed to conduct the trial for recurrent ependymoma.
• In the first stage, we will enroll 18 patients with RELA-fusion ependymoma and if 4 or more patients in Cohort 1 are progression free at 6 months, we will proceed to stage 2; otherwise, we will terminate the trial and conclude that marizomib is not effective.
• In the second stage, we will enroll 32 patients with non RELA-fusion ependymoma.
• Patients will be treated with marizomib in cycles consistent of 28 days until disease progression or a maximum of 24 cycles.

• Study Type: Interventional
• Enrollment (Actual): 4
• Phase: Phase 2

• Treatment with any investigational agent within 28 days before enrollment.
• History of any other cancer (except non-melanoma skin cancer or carcinoma in-situ of the cervix), unless patient is in complete remission and off all therapy for that disease for a minimum of 3 years.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to marizomib.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
• Inadequately controlled hypertension (defined as systolic blood pressure > 140 mmHg and/or diastolic blood pressure > 90 mmHg).
• Current active hepatic or biliary disease (with exception of patients with Gilbert's syndrome, asymptomatic gallstones, or stable chronic liver disease per investigator assessment).

• History of myocardial infarction or unstable angina within 3 months prior to enrollment.
• A marked baseline prolongation of QT interval (QT)/corrected QT interval (QTc) (e.g., repeated demonstration of a QTc interval >480 milliseconds (ms) (CTCAE grade 1) using Frederica's QT correction

formula.

• A history of additional risk factors for Torsades de Pointes (TdP) (e.g., heart failure, hypokalemia, family history of Long QT Syndrome).
• Current use of concomitant medications that prolong the QT/QTc interval
• History of stroke or transient ischemic attack within 3 months prior to enrollment.
• Pregnant women are excluded from this study because marizomibs potential for teratogenic or abortifacient effects is unknown. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with marizomib, breastfeeding should be discontinued if the mother is treated with marizomib.
• Patients receiving combination antiretroviral therapy for treatment of Human Immunodeficiency Virus (HIV) or active anti-viral treatment for Hepatitis A, B or C infection. Anti-viral therapy, when combined with marizomib, poses a potential for pharmacokinetic interactions. Marizomib also increases immunosuppression, placing patients at an increased risk of acquiring lethal infections. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.
• Inclusion Criteria for Pregnancy Cohort (P)

Because the drug manufacturer would like to study the effect of the study therapy on pregnancy, and because the required information cannot be collected unless a subject is enrolled per ruling of the OGC, the following additional groups of subjects may be enrolled if necessary.

-A child whose parent (male or female) is/was an active participant in the study at any time during the childs gestation. Active participant is defined as having received at least one dose of study therapy through 6 months after the last dose of study therapy.

OR

• An expectant mother of child whose father is/was an active participant in the study at any time during the childs gestation. The father must have received at least one dose of study therapy.
