Autologous CMV-Specific Cytotoxic T Cells and Temozolomide in Treating Patients With Glioblastoma

A Phase I/II Clinical Trial of Autologous CMV-Specific Cytotoxic T Cells for GBM Patients

This phase I/II trial studies the side effects and best dose of autologous cytomegalovirus (CMV)-specific cytotoxic T cells when given together with temozolomide and to see how well they work in treating patients with glioblastoma. Autologous CMV-specific cytotoxic T cells may stimulate the immune system to attack specific tumor cells and stop them from growing or kill them. Drugs used in chemotherapy, such as temozolomide, may work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving autologous CMV-specific cytotoxic T cells with temozolomide may be a better treatment for patients with glioblastoma.

PRIMARY OBJECTIVES:

I. To determine the maximum feasible dose (MFD) or maximum tolerated dose (MTD) and safety of cytomegalovirus (CMV)-specific T cells in combination with dose-dense temozolomide in patients with recurrent glioblastoma. (Phase I) II. To evaluate the immunological effects in resected glioblastoma after intravenous administered cytomegalovirus (CMV)-stimulated adoptive T cells in patients with recurrent glioblastoma (GBM). (Phase II: recurrent glioblastoma undergoing resection) III. To correlate 6-month progression-free survival rate (PFS6) with objective clearance of CMV antigens as measured by immunohistochemistry (IHC) and by ex vivo T-cell-specific effector responses using intracellular cytokine profiling. (Phase II: recurrent glioblastoma undergoing resection) IV. Overall survival (OS). (Phase II: newly diagnosed glioblastoma)

SECONDARY OBJECTIVES:

I. Time to progression, overall survival (OS) as well as immunological reactivity and safety. (Phase II: recurrent glioblastoma undergoing resection) II. Safety and tolerability of dose-dense temozolomide in combination with intravenous administered CMV-stimulated adoptive T cells in patients receiving adjuvant therapy after completing external beam radiotherapy with concurrent temozolomide for newly diagnosed glioblastoma. (Phase II: newly diagnosed glioblastoma) III. Overall objective response rate (ORR), median duration of response, PFS6. (Phase II: newly diagnosed glioblastoma)

EXPLORATORY OBJECTIVES:

I. To determine the persistence and expansion of adoptively-infused CMV-specific T cells by multiparameter flow cytometry in serially-sampled peripheral blood. (Phase I) II. To identify imaging characteristics such as magnetic resonance imaging (MRI) textural analysis associated with immunological changes in tumor following treatment with CMV-stimulated adoptive T cells. (Phase II: recurrent glioblastoma undergoing resection) III. To ascertain if adoptive transfer of CMV-specific T cells leads to the expansion of T cells with specificity to other glioblastoma antigens (i.e. epitope spreading) by performing longitudinally monitoring of antigen-specific T cell frequency with enzyme-linked immunosorbent spot assay (ELISPOT). (Phase II: recurrent glioblastoma undergoing resection) IV. To determine the persistence and expansion of adoptively-infused CMV-specific T cells by multiparameter flow cytometry in serially-sampled peripheral blood. (Phase II: newly diagnosed glioblastoma)

OUTLINE: This is a phase I, dose-escalation study of CMV-specific T cells followed by a phase II study. Patients are assigned to 1 of 2 treatment arms.

ARM I: Patients receive temozolomide orally (PO) once a day (QD) on days 1-21 and CMV-specific T cell transfer intravenously (IV) over 1-5 minutes on day 22. Patients undergo surgery on day 30 of cycle 1. Treatment repeats every 42 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive temozolomide PO QD on days 1-21. Treatment repeats every 42 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive temozolomide PO QD on days 1-21 and CMV-specific T cell transfer intravenously IV over 1-5 minutes on day 22. Treatment repeats every 42 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive temozolomide PO QD on days 1-5. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and every 3 months.

Inclusion Criteria:

• Be willing and able to provide written informed consent for the trial
• PHASE II DOSE EXPANSION IN RECURRENT GBM UNDERGOING RESECTION: Have histologically confirmed World Health Organization grade IV malignant glioma (glioblastoma or gliosarcoma); participants will also be eligible if the original histology was lower grade glioma and there is suspected transformation to glioblastoma based on imaging findings; if the final pathology report after resection fails to confirm recurrent glioblastoma or gliosarcoma, the subject will be followed for adverse events (AEs) and survival, but excluded for other primary and secondary objective analysis; the subject will be replaced
• PHASE II DOSE EXPANSION IN NEWLY DIAGNOSED GBM: Have histologically confirmed World Health Organization grade IV glioma (glioblastoma or gliosarcoma)
• PHASE II DOSE EXPANSION IN RECURRENT GBM UNDERGOING RESECTION: Be at first relapse; Note: relapse is defined as progression following initial therapy (i.e., radiation, chemotherapy, or radiation plus (+) chemotherapy); if the participant had a surgical resection for relapsed disease and no antitumor therapy instituted for up to 12 weeks, this is considered one relapse; for participants who had prior therapy for a lower grade glioma, the surgical diagnosis of glioblastoma or gliosarcoma will be considered first relapse
• PHASE II DOSE EXPANSION IN NEWLY DIAGNOSED GBM: Patients must have completed standard radiation therapy with concurrent temozolomide (TMZ) within 5 weeks (wks) of enrollment and must not have evidence of progressive disease on post treatment imaging; progression can only be defined using diagnostic imaging if there is new enhancement outside of the radiation field (beyond the high-dose region or 80% isodose line) or if there is unequivocal evidence of viable tumor on histopathologic sampling (e.g., solid tumor areas [i.e,> 70% tumor cell nuclei in areas], high or progressive increase in mindbomb homolog 1[MIB-1] proliferation index compared with prior biopsy, or evidence for histologic progression or increased anaplasia in tumor); Note: given the difficulty of differentiating true progression from pseudoprogression, clinical decline alone, in the absence of radiographic or histologic confirmation of progression, will not be sufficient for definition of progressive disease in the first 12 weeks after completion of concurrent chemoradiotherapy
