This phase I trial studies best dose and side effects of oncolytic adenovirus DNX-2401 in treating patients with high-grade glioma that has come back (recurrent). Oncolytic adenovirus DNX-2401 is made from the common cold virus that has been changed in the laboratory to make it less likely to cause an infection (such as a cold). The virus is also changed to target brain cancer cells and attack them.
Full description
PRIMARY OBJECTIVES:
I. To determine the maximal tolerated dose (MTD) of allogeneic bone marrow-derived human mesenchymal stem cells (BM-hMSCs) loaded with the oncolytic adenovirus DNX-2401 (BM-hMSCs-DNX2401) administered by intra-arterial injection (i.e., transfemoral endovascular intracranial injection) in patients with recurrent glioblastoma (GBM), IDH-mutant astrocytoma grade 4, gliosarcoma, or wild-type IDH-1 anaplastic astrocytoma.
II. To determine the local and systemic toxicity of allogeneic BM-hMSCs-DNX2401 administered by intra-arterial injection (i.e., transfemoral endovascular intracranial injection) in patients with recurrent GBM, gliosarcoma or wild-type IDH-1 anaplastic astrocytoma.
III. To determine at the molecular and cellular level the capacity of allogeneic BM-hMSCs-DNX2401 administered intra-arterially to home to and deliver DNX-2401 to recurrent GBM, gliosarcoma or wild-type IDH-1 anaplastic astrocytoma by analyzing post-treatment surgical brain tumor specimens for the expression and distribution of adenoviral proteins.
SECONDARY OBJECTIVES:
I. To assess shedding of adenovirus into the blood, sputum, and nasopharynx after intra-arterial administration of BM-hMSCs-DNX2401 in patients with recurrent GBM, gliosarcoma or wild-type IDH-1 anaplastic astrocytoma.
II. To assess the development of anti-adenovirus antibodies after intra-arterial administration of BM-hMSCs-DNX2401 in patients with recurrent GBM, gliosarcoma or wild-type IDH-1 anaplastic astrocytoma.
III. To evaluate immune-mediated cytokine responses after intra-arterial administration of BM-hMSCs-DNX2401 in patients with recurrent GBM, gliosarcoma or wild-type IDH-1 anaplastic astrocytoma.
IV. To assess anti-tumoral activity and to determine progression-free survival (PFS) and overall survival (OS) after intra-arterial administration of BM-hMSCs-DNX2401 in patients with recurrent GBM, gliosarcoma or wild-type IDH-1 anaplastic astrocytoma.
OUTLINE: This is a dose-escalation study.
PART I: Patients receive one or two infusions of BM-hMSCs-DNX-2401 intra-arterially (IA) over 20-30 minutes on day 0. Dose level 1-5 will receive 1 infusion. Dose level 6 will receive 2 infusions.
PART II: Patients receive one or two infusions BM-hMSCs-DNX-2401 IA, depending on the highest dose that was tolerated in Part 1. After 2 weeks, patients undergo surgery where the tumor is removed, then receive intramural injection of BM-hMSCs-DNX-2401 into the resection cavity.
After completion of study treatment, patients in both part I and II are followed up on days 1, 4, 7, and 14 of month 1,every 6 weeks for 6 months (4 visits), then every 8 weeks for 1 year (6 visits), then every 4 months for 1 year (3 visits), then every 6 months until the tumor grows back. Patients treated at Dose level 6 in Part 1 and Part 2 are also followed up on Day 12, then on Day 1, 4, and 7 after second infusion, then on Day 1, 7, and 14 post-craniotomy for Part 2, Dose Level 6, then ,every 6 weeks for 6 months (4 visits), then every 8 weeks for 1 year (6 visits), then every 4 months for 1 year (3 visits), then every 6 months until the tumor grows back.

Inclusion criteria
Subjects must meet the following inclusion criteria to be eligible and enroll:
Subjects must be willing and able to provide informed consent, undergo and comply with all study assessments, and adhere to the protocol schedule.
Patients with recurrent malignant GBM or gliosarcoma will be eligible. Patients with recurrent anaplastic astrocytoma with wild-type IDH-1 gene will also be eligible if there is a significant enhancing mass on MRI (≥1.0 cm in diameter with upper limit of 5 cm maximal diameter) because their prognosis/behavior is similar to GBM. Subjects with an initial diagnosis of an IDH-mutant grade 2 or 3 astrocytoma are also eligible at recurrence if a biopsy at recurrence is determined to be IDH-mutant grade 4 astrocytoma, and there is a significant enhancing mass on MRI (≥1.0 cm in diameter with upper limit of 5 cm maximal diameter). A pathology report constitutes adequate documentation of histology for study inclusion.
Patients must show unequivocal evidence for tumor recurrence or progression by MRI scan after failing prior surgical resection, biopsy, chemotherapy or radiation. A baseline MRI must be performed within 24 days prior to registration. Biopsy is encouraged at the time of recurrence if it is unclear that there is recurrent tumor. However, biopsy is not required if the practicing physician thinks that there is adequate radiographic and clinical evidence for recurrence.
Male or female patients ≥ 18 years of age.
Patients must be able to undergo endovascular treatment based on Doppler studies showing ICA that is less than 50% occluded.
For patients undergoing resection for biological endpoints, tumors must be surgically resectable at the time of baseline evaluation and craniotomy for tumor resection is indicated as part of their standard medical care.
Tumors must be ≥1.0 cm in diameter with upper limit of 5 cm maximal diameter.
Patients must have a Karnofsky performance score ≥ 70.
Patients must have a life expectancy of at least 16 weeks.
Patients must have adequate bone marrow function (absolute granulocyte count > 1,500 and platelet count of > 75,000), adequate liver function (SGPT and SGOT and bilirubin < 2 times institutional normal ranges), and adequate renal function (creatinine < 2.0 times institutional normal) prior to starting therapy.
Prothrombin time/international normalized ratio (PT/INR) or partial thromboplastin time (PTT) ≤ 1.5x ULN.
Subjects who have received the following chemotherapies must have completed them within the following time periods prior to Baseline/Day 0 of hMSC-DNX2401 delivery with recovery from any drug-related toxic effects to Grade 1, or less, severity:
This study was designed to include women and minorities, but was not designed to measure differences of intervention effects. Males and females will be recruited with no preference to gender.
No exclusion to this study will be based on race. Minorities will actively be recruited to participate. The malignant glioma patient population treated at MDACC over the past year is as follows:
Patients must be 8 weeks from radiotherapy to minimize the potential for MRI changes related to radiation necrosis that might be misdiagnosed as progression of disease, or 4 weeks if a new lesion, relative to the pre-radiation MRI, develops that is outside the primary radiation field (beyond 80% isodose line). However, if a biopsy is undertaken prior to these times and this biopsy documents histological evidence for recurrent disease, then patients will be eligible regardless of the time after radiation.
Patients must be willing to forego other cytotoxic and non-cytotoxic drug or radiation therapy against the tumor while enrolled in the study.
Women of childbearing potential must have a negative urine or serum pregnancy test at screening.
Subjects and their partners must be willing to use effective birth control during the study and for up to 6 months following administration of hMSC-DNX2401. Birth control that is acceptable to use in this study:
