Study Title | Metabolomic analysis to assess response to immunotherapy for malignant brain tumors: Part 3 |
Study Type | Cancer surrogate biomarker discovery |
Study Summary | An effective immune response in patients with cancer treated with immunotherapy includes dendritic cell (DC) activation and migration followed by stimulation of CD8 and CD4 T cells. This then leads to the activation, proliferation and further activation of other immune cell populations including NK cells or immunosuppressive populations such as Tregs and myeloid derived suppressor cells (MDSCs). These studies were carried out utilizing murine brain tumor models treated with an RNA DC vaccine platform. We hypothesized that metabolomic analyses of urines would be sensitive to the action of this diverse set of immune cells. The objective of this study was to evaluate the feasibility of using metabolomics to follow immune responses after immunotherapy. We chose NMR as our analytical technique of choice, as it has many favorable qualities that make it ideal for analyses of urine. |

Treatment:
Treatment ID: | TR002307 |
Treatment Summary: | DC vaccine treatment Naïve C57/BL6 mice were used for tumor implantation. B16F10-OVA (2 × 104 cells/brain) tumor cell lines were injected intracranially. Antigen specific T cells (3 × 107 cells/50 µL of PBS) were infused into the animals intravenous (IV) five days after tumor implantation and the DC vaccine (1x106 cells/50 µL of PBS per animal) was injected intradermally on the same day. Both antigen-specific T cells and DC vaccine were administered once. Urine samples were collected after DC vaccination at several timepoints. Finally, animals were euthanized when they reached the endpoints. Sample collection Each animal was in a separate chamber individually. The chamber bottom was covered with clean parafilm. Animals were kept in the chamber until urination. Urine drops were collected using sterile syringes. Samples were stored at -80 °C until further analysis. Serum samples were collected from peripheral blood. |
Animal Anesthesia: | isoflurane |
Animal Fasting: | non-fasted |
Animal Endp Euthanasia: | Euthanasia was carried out by thoracotomy followed by cervical dislocation. |
