18The primary objective of this study is to evaluate the safety of autologous dendritic killer cell (DKC) in patients with metastatic solid tumor and to evaluate the maximum tolerated dose (MTD) of DKC. The primary endpoint of safety evaluation includes physical examination, assessment of vital sign, laboratory test, concomitant medication, and adverse event (AE). The secondary endpoints regarding efficacy includes the generation of tumor specific immune response by detecting CD3+ CD8+ CD69+ IFN-gamma+ T cells, and the improvement of quality of life
DKC is a hybrid cell type capable of dual functionality, i.e. cytotoxicity and antigen presentation, similar to NK cells and DCs, respectively.
All enrolled patients received one treatment cycle of DKC cell therapy, which consists of 5 infusion cycles approximately 23 days apart. There were 3 dose levels: 5 x 10^6, 1 x 10^7, and 5 x 10^7 cells, and the protocol followed a traditional 3+3 dose escalation design.
Inclusion Criteria: Capable and willing of providing signed informed consent before study Patient age ≥20 at date of consent Performance status (ECOG) ≤2 Patients have a life expectancy of > 3 months Patients agree to be in compliant to clinical protocol planned treatment plan Histologically confirmed metastatic solid tumor, including colon cancer, gastric cancer, pancreatic cancer, bile duct cancer, liver cancer Patient with histological and conventional imaging proven measurable lesion Patients not pregnant.
