What was measured

The relative difference in CD8 T cell counts before and after administration of the TT booster vaccine (Day 8) will be compared. The number of cells per microliter (cells/µL) will be determined. The proportion of at least 3-fold increase will be reported along with its 95% CI. The actual magnitude of change will be examined by taking a log scale of CD8 counts and report a mean of change on CD8 on its log scale along with its 95% CI.

Analysis population: Blood samples were collected and analyzed by flow cytometry as well as by ELISPOT.

Groups in this outcome

Gemcitabine With TT Vaccine Booster

Gemcitabine will be delivered as is standard of care. Patients diagnosed with pancreatic ductal carcinoma (PCD) will be treated with Gemcitabine and boosted once with the human childhood vaccine to TT Gemcitabine: Gemcitabine will be administered on days 1, 8, 15 every 28 days TT vaccine booster: One human TT childhood vaccine booster will be administered on day 8
