Combination of Anti-PD-1 and NK Immunotherapy for Recurrent Solid Tumors

Combination of Anti-PD-1 and NK Immunotherapy for Recurrent Solid Tumors

The aim of this study is the safety and efficacy of anti-PD-1 plus NK immunotherapy to multiple solid tumors.

By enrolling patients with solid tumors adapted to enrolled criteria, this study will document for the first time the safety and the short and long term efficacy of the combined therapy using anti-PD-1 and natural killer (NK) cells.

The safety will be evaluated by statistics of adverse reactions. The efficacy will be evaluated according to local relief degree, progress free survival (PFS) and overall survival (OS).

• All standard therapies have failed according to NCCN guidelines or the patient refuses standard therapies after cancer recurrence
• Progression after chemotherapy or appropriate TKI treatment for those patients with an EGFR-sensitizing mutation or ALK rearrangement
• KPS ≥ 70, lifespan > 3 months, PD-L1 TPS of 1% or greater
• Platelet count ≥ 80×10^9/L，white blood cell count ≥ 3×10^9/L, neutrophil count ≥ 2×10^9/L, hemoglobin ≥ 80 g/L

Exclusion Criteria:

• Patients with cardiac pacemaker
