Immunologic Factors

All participants will receive 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.

Participants will receive 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

TTRNA-DC vaccines with GM-CSF

Participants will receive a single infusion of autologous CD34+ HSCs

Autologous Hematopoietic Stem cells (HSCs)

Participants will receive a single infusion of ex vivo expanded tumor-reactive T cells

TTRNA-xALT

All patients will receive a full Td booster IM vaccine 4-24 hours prior to Vaccine #1 and vaccine site pretreatment with a one-fifth dose of Td intradermally, at the site of planned vaccine, 4-24 hours prior to vaccines #3, #5, #7 and #9.

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.
