研究概览
简要总结
The 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

结局指标
主要结局
Safety of DKC as assessed by serious adverse event (SAE)
时间窗: Entire treatment period (cycle 1-5, 116 +/- 4 days) and follow-up period (452 +/- 4 days)
Serious adverse event incidence is summarized descriptively by system organ class and preferred term for each cohort and overall trial. The causality of SAEs will be assessed by the principal investigator for its relationship to study medication.
Safety of DKC as assessed by dose-limiting toxicity (DLT)
时间窗: Entire treatment period (cycle 1-5, 116 +/- 4 days) and follow-up period (452 +/- 4 days)
DLT is defined as Grade ≧ 3 (according to NCI-CTCAE 4.03 grading system), study medication-related (i.e. with causality determined as at least possibly related to study medication), and worsened in comparison to baseline (pre-treatment condition). DLT is determined after first infusion cycle and maximum tolerated dose (MTD) is determined as the highest dose without DLT. DLT is defined by the items listed below: Blood and lymphatic system disorders: Grade ≧ 3 of (1) Any febrile neutropenia, (2) Leukocytosis, (3) Anemia Other disorders: Grade ≧ 3 of (1) Diarrhea, (2) Vomiting, (3) Fever, (4) Nausea, (5) Anaphylaxis
Safety of DKC as assessed by combining with concomitant anticancer treatment
时间窗: Entire treatment period (cycle 1-5, 116 +/- 4 days) and follow-up period (452 +/- 4 days)
The subjects enrolled in the study are cancer patients, who were treated with anticancer drugs before, and possibly during, DKC immunotherapy. Potential adverse drug-drug interaction (DDI) is monitored during treatment and follow-up period.
Safety of DKC as assessed by laboratory examinations
时间窗: Entire treatment period (cycle 1-5, 116 +/- 4 days) and follow-up period (452 +/- 4 days)
For each cohort, there are 5 baselines (taken 9 days before infusion) for 5 infusion cycles, and there are 2 evaluation time points in each infusion cycle (at end of first week and second week after infusion) and 4 in the follow-up period (at every 12 weeks). The laboratory evaluation results are tabulated in two aspects: 1) the percentage changes between each evaluation and corresponding baselines, and 2) the mean baseline values of each cycle in each cohort. Laboratory results regarding different functional categories are described separately in following areas. Hematology related items: Hb (g/dL), WBC (count/uL), Platelet (x 10\^3 count/uL), ANC (count/uL) Liver function related items: C-RP (mg/dL), Glucose AC (mg/dL), Total Bilirubin (mg/dL), AST (U/L), ALT (U/L), LDH (U/L), ALP (U/L), gammaGT (U/L) Serum lipids and proteins, renal function, and electrolytes related items: HDL-C (mg/dL), Total Cholesterol (mg/dL), Triglyceride (mg/dL), Creatinine (mg/dL), BUN (mg/dL)
Safety of DKC as assessed by adverse event (AE)
时间窗: Entire treatment period (cycle 1-5, 116 +/- 4 days) and follow-up period (452 +/- 4 days)
The coding system used for AE is MedDRA. Only treatment-emergent adverse events (TEAEs) are considered for primary endpoint. Frequency table of subjects with pre-treatment and treatment-emergent AE are presented by each cohort and overall trial. AE incidents are summarized descriptively by system organ class and preferred term using MedDRA for each cohort and overall trial.
