This study will enroll 6 DLT evaluable subjects (up to 12 patients total) where we will evaluate feasibility and safety of adoptive cellular therapy in patients with recurrent or progressive oligodendroglioma WHO grade 2 and WHO grade 3.

After screening consent, subjects will undergo standard of care resection or biopsy for confirmatory diagnosis of disease progression and aseptic collection of tumor material for DNA and RNA extraction and sequencing, amplification, and loading of autologous DCs. Following biopsy and confirmatory pathologic diagnosis, eligible patients will be enrolled in treatment.

After surgery, patients will undergo a G-CSF mobilized pheresis to collect PBMCs for DC generation and CD34+ HSCs. Amplified tumor RNA obtained from surgically resected or biopsied specimens will be used to generate total tumor RNA-pulsed DCs (TTRNA-DCs) manufactured while patients initiate salvage chemotherapy regimen after surgery.

Salvage chemotherapy with IDH1/2 inhibitor will initiate 1-2 weeks after G-CSF mobilized leukapheresis for 1-3 cycles after which, treatment cycles will be paused, and the patients will receive 3 priming TTRNA-DCs vaccines every 2 weeks and undergo a non-mobilized leukapheresis to collect vaccine-boosted lymphocytes for ex vivo T cell expansion and generation of additional TTRNA-DC vaccines. Treatment with IDH1/2 inhibitor will resume with monthly TTRNA-DC vaccines for an additional 1-3 cycles until ex vivo expanded T cells are manufactured.

For ACT, patients will undergo non-myeloablative conditioning with cyclophosphamide /fludarabine. The total immunotherapy regimen will consist of up to 9 intradermal DC vaccines (three -bi-weekly (q2 weeks) for priming, monthly for additional 2-3 cycles during T cell expansion, and three bi-weekly during T cell engraftment), a single i.v. infusion of ex vivo expanded tumor-reactive T cells, and a i.v. single infusion of autologous HSCs.

The duration of treatment from enrollment to completion of DLT window is anticipated to be 7 to 9 months.

ADAGiO: Adoptive Cellular Therapy for the TreAtment of Recurrent OliGodendrogliOma (OG) Adult Patients

Feasibility will be measured by the number of patients who receive autologous dendritic cells, T cells and hematopoietic stem cells that meet the FDA IND defined quality assurance and quality control release criteria. A minimum of 66.7% of enrolled subject must achieve this criterion for feasibility endpoint.

Safety will be defined as \< 1 DLT out of six enrolled and treated subjects during the defined period of administration of ex vivo expanded TTRNA T cells through 6 weeks post infusion. Investigational treatment related CTCAE V5.0 adverse events 1) Grade III or greater non-neurologic toxicity; 2) Grade III neurologic toxicity that does not improve to Grade II or better within 5 days; or 3) Grade IV neurologic toxicity will be recorded toward DLT.

TTRNA-DC vaccines with GM-CSF and TTRNA-xALT plus Td vaccine with Autologous Hematopoietic Stem cells (HSCs) during cycles of Dose-intensified TMZ

TTRNA-DC vaccines with GM-CSF and TTRNA-xALT plus Td vaccine with Autologous Hematopoietic Stem cells (HSCs) with Cyclophosphamide + Fludarabine Lymphodepletive Conditioning

After chemoradiation subjects will receive the first cycle of dose-intensified TMZ followed by three biweekly TTRNA-DC vaccines with GM-CSF. Monthly DC vaccines will be given during TMZ Cycles 2-5 for Groups A and B and 48-96 hours after completion of TMZ Cycle 6 Day 21 for Group A and 12-36 hours after HSCs for Group B. All subjects will receive an additional two bi-weekly vaccines during Cycle 6 for a total of 10 DC vaccines. All DC vaccines will be embedded with GM-CSF (150 µg per injection) and given intradermal.

During TMZ Cycle 4 and with DC vaccine #6, an infusion of T-cells will be administered to all subjects.

Subjects in Group B, however, will receive lymphodepletion with cyclophosphamide + fludarabine after DC vaccination and prior to the intravenous infusion of ex vivo expanded tumor-reactive lymphocytes.

Cyclophosphamide + Fludarabine Lymphodepletive Conditioning

After chemoradiation, subjects in Group A will receive the first cycle of dose-intensified TMZ followed by three biweekly TTRNA-DC vaccines with GM-CSF. All subjects will have an additional five cycles of dose-intensified TMZ (for a total of 6 Cycles) with concurrent monthly DC vaccinations.

Dose-Intensified TMZ

A full Td booster vaccine will be administered IM at Vaccine #1 to all subjects, and vaccine site pretreatment will be administered to all subjects prior to Vaccine#3, #6, and #8.

During Cycle 4, all patients will receive HSCs prior to xALT infusion and DC vaccine #6.

The standard of care for children with DIPG includes focal radiotherapy (RT) but outcomes have remained dismal despite this treatment. The addition of oral Temozolomide (TMZ) concurrently with RT followed by monthly TMZ was also found to be safe but ineffective. Recent studies in adults have shown that certain types of chemotherapy induce a profound but transient lymphopenia (low blood lymphocytes) and vaccinating and/or the adoptive transfer of tumor-specific lymphocytes into the cancer patient during this lymphopenic state leads to dramatic T cell expansion and potent immunologic and clinical responses. Therefore, patients in this study will either receive concurrent TMZ during RT and immunotherapy during and after maintenance cycles of dose-intensive TMZ (Group A) or focal radiotherapy alone and immunotherapy without maintenance DI TMZ (Group B). Immune responses during cycles of DC vaccination with or without DI TMZ will be evaluated in both treatment groups.

The standard of care for children with DIPG includes external beam focal radiotherapy (RT) but outcomes have remained dismal despite this treatment. The addition of oral Temozolomide (TMZ) concurrently with focal irradiation followed by maintenance monthly TMZ was also found to be safe but ineffective. However, in the context of an immunotherapy strategy, it might be beneficial to use TMZ as an adjuvant therapy during and following radiotherapy. Recent pre-clinical and clinical studies in adults with have shown that both myeloablative (MA) and non-myeloablative (NMA) chemotherapy induce a profound but transient lymphopenia and, somewhat counterintuitively, vaccination during recovery from this lymphopenic state and/or the adoptive transfer of tumor-specific lymphocytes into lymphodepleted hosts leads to dramatic in vivo T cell expansion and potent immunologic and clinical responses. Therefore, the study team expects that tumor-specific lymphocytes, expanded ex vivo with the use of TTRNA-pulsed DCs may provide a source of lymphocytes that preferentially expand in this lymphopenic environment following TMZ, and serve as a source of responder cells to subsequent DC vaccination.

TMZ induces profound lymphopenia in children with central nervous system (CNS) tumors. It has not been conclusively shown to help in augmenting vaccine-induced immune responses in this population. Patients in this study will either receive concurrent TMZ during RT and immunotherapy during and after maintenance cycles of dose-intensive TMZ (Group A) or focal radiotherapy alone and immunotherapy without maintenance DI TMZ (Group B). Immune responses during cycles of DC vaccination with or without DI TMZ will be evaluated in both treatment groups. The immunotherapy regimen will consist of TTRNA-DC vaccines alone followed by adoptive cellular therapy consisting of ex vivo expanded tumor-reactive lymphocytes coupled with TTRNA-DC vaccines and autologous HSCs.

Patients in Group B will not receive DI TMZ, however, they will receive lymphodepletion with cyclophosphamide + fludarabine after DC vaccination and prior to the intravenous infusion of ex vivo expanded tumor-reactive lymphocytes. T cell engraftment and persistence has been shown to be augmented by lymphodepletion in numerous studies. TTRNA-pulsed DCs will be given in conjunction with the adjuvants GM-CSF and tetanus-diphtheria toxoid (Td) vaccine which the study team have shown can significantly enhance clinical responses to DC vaccination.

Patients in this study will either receive concurrent TMZ during RT and dose-intensive TMZ as maintenance treatment (Group A) or radiotherapy only prior to DC vaccination and without maintenance DI TMZ (Group B). Immune responses during cycles of DC vaccination with or without DI TMZ will be evaluated in both treatment groups.

Once Group A accrual is completed and evaluated for toxicity, 6 Group B patients will be enrolled and treated at the Maximally Achievable Dose (MAD) or (Maximum Tolerated Dose) MTD determined in Group A cohort.

Number of subjects with immunotherapy-related dose-limiting toxicities including 1) Grade III or greater non-neurologic toxicity; 2) Grade III neurologic toxicity that does not improve to Grade II or better within 5 days; or 3) Grade IV neurologic toxicity.

The first 6 patients in Group A (receiving DI TMZ) at a dose of 3 x 107 cells /kg xALT and if dose-limiting toxicities are observed in no more than 1 of 6 patients, the study team will enroll another 6 patients at the next dose level of 3 x108 cells /kg. If no more than 1 patient suffers dose limiting toxicity (DLT) at this dose level, it will declared the MAD of T cells. Subjects enrolled in Group B will be treated at the MAD or MTD determined in the Group A Cohort.

The in vivo expansion, persistence, and function of tumor-specific lymphocytes will be followed serially in these patients using T-cell receptor (TCR) sequencing and functional immunologic analysis.

Dose-intensified TMZ with TTRNA-DC vaccines with GM-CSF and TTRNA-xALT plus Td vaccine without Autologous Hematopoietic Stem cells (HSCs)

Dose-intensified TMZ with TTRNA-DC vaccines with GM-CSF and TTRNA-xALT plus Td vaccine with Autologous Hematopoietic Stem cells (HSCs)

After chemoradiation, subjects will receive the first cycle of dose-intensified TMZ followed by three biweekly TTRNA-DC vaccines with GM-CSF. All subjects will have an additional five cycles of dose-intensified TMZ (for a total of 6 Cycles) with concurrent monthly DC vaccinations.

Dose-intensified TMZ

Prior to chemoradiation, enrolled subjects will undergo a mobilized leukapheresis for collection of PBSCs and PBMCs for generation of DCs. One group will receive recommended dose of \> 2 x 106 CD34+ HSCs/kg. Subjects enrolled in Group B will receive HSCs during TMZ Cycle 6 before receiving DC vaccine and T-cell infusion.

During TMZ Cycle 6 and with DC vaccine #8, an infusion of T-cells will be administered to all subjects.

It is believed that the body's immune system protects the body by attacking and killing tumor cells. T-lymphocytes (T-cells) are part of the immune system and can attack when they recognize special proteins on the surface of tumors. In most patients with advanced cancer, T-cells are not stimulated enough to kill the tumor. In this research study, we will use a patient's tumor to make a vaccine which we hope will stimulate T-cells to kill tumor cells and leave normal cells alone.

High grade gliomas (HGGs) are very aggressive and difficult for the body's immune system to attack. Before T-cells can become active against tumor cells, they require strong stimulation by special "stimulator" cells in the body called Dendritic Cells (DCs) which are also part of the immune system. DCs can recognize the cancer cells and then activate the T lymphocytes, and create this strong stimulation.

The purpose of this research study is to learn whether anti-tumor T-cells and anti-tumor DC vaccines can be given safely. Most importantly, this study is also to determine whether the T-cells and DC vaccines can stimulate a person's immune system to fight off the tumor cells in the brain.

Most importantly, this study is also to determine whether the T-cells and DC vaccines can stimulate your immune system to fight off the tumor cells in your brain. When the vaccine for this study is made, dendritic cells will be loaded with genetic material called RNA (ribonucleic acid) from your tumor to stimulate the dendritic cells. The vaccine has two components given at different times after chemoradiation and throughout chemotherapy cycles. The first part, the DC vaccine, involves RNA loaded dendritic cells that are given under the skin at several time points in the study and the second part, xALT vaccine, is a single infusion of tumor-specific T cells delivered through one of two peripheral IV catheters that are placed prior to infusion. This vaccine is investigational which means that it is not approved by the US Food and Drug Administration (FDA) and is being tested in research studies.

It is hoped that by injecting the DC vaccine into your skin and infusing the T-cells into your blood, your immune system will be activated against the tumor. Once it is activated against the tumor, your immune system may recognize and attack the tumor cells in your brain and not attack normal cells. Use of a vaccine that stimulates your immune system is called immunotherapy.
