MC240903 Ex Vivo Expansion of Tumor Antigen-Specific T Cells for Adoptive T Cell Therapy
Summary
The purpose of this study is to understand how the body's immune cells respond to a new type of vaccine (neoantigen vaccine) designed to help the immune system recognize and fight cancer. To do this, the study team will collect a research specimen from participants to study their immune cells' reactions to the neoantigen vaccine. This research will help researchers learn more about how these vaccines might work to protect or treat against cancer.
Arms & interventions
- ProcedureBlood Draw
Participants have a standard blood draw or apheresis on study. Some participants may provide a specimen via apheresis one time (the "blood draw group") and then elect to provide a second optional specimen via a standard blood draw (the "apheresis draw group") or vice versa.
- ProcedureApheresis
Participants have a standard blood draw or apheresis on study. Apheresis is a procedure where blood is drawn from your body, specific components like plasma, platelets, and/or white blood cells are separated out, and the rest of the blood is returned. Some participants may provide a specimen via apheresis one time (the "apheresis group") and then elect to provide a second optional specimen via a standard blood draw (the "blood draw group") or vice versa.
Outcome measures
Primary
Immune effector networks
Specimen samples obtained by blood draw and/or apheresis will be analyzed to identify immune effector networks that accelerate ex vivo expansion of antigen-specific memory precursor T cells. All tests will be two sided with a p\<0.05 being considered as statistically significant.
Time frame: Baseline; up to 3 years
Dendritic cell signaling programs
Specimen samples obtained by blood draw and/or apheresis will be analyzed to define dendritic cell signaling programs that foster generation of polyfunctional, high avidity antigen-specific T cells capable of recognizing naturally processed tumor antigen. All tests will be two sided with a p\<0.05 being considered as statistically significant.
Time frame: Baseline; up to 3 years
Cytokine capture methods
Specimen samples obtained by blood draw and/or apheresis will be analyzed to identify cytokine capture methods for isolation of antigen-specific T cells. All tests will be two sided with a p\<0.05 being considered as statistically significant.
Time frame: Baseline; up to 3 years
