Neoantigen-loaded DC Vaccine, PD-1 Inhibitor, and Radiotherapy for Advanced NSCLC Progressed After Second-line Treatment

Radiotherapy will be completed prior to the administration of personalized tumor neoantigen-loaded DC vaccine and PD-1 inhibitors. The treatment cycle, frequency, and dosage are determined by the subject's primary physician based on the specific conditions of the participant.

Treatment with PD-1 inhibitors will begin after the completion of radiotherapy, with a treatment cycle of 3 weeks. On the first day (D1) of each treatment cycle, the drug is administered intravenously, with the dosage according to the instructions.

The treatment with personalized tumor neoantigen-loaded DC vaccine is divided into two periods: the primary phase and the boost phase. The primary phase consists of 6 treatments, with the first 3 treatments spaced one week apart and the subsequent 3 treatments spaced two weeks apart. Vaccine will be administrated on the fourth day (D4) of that week. The boost phase consists of 4 treatments, each spaced three weeks apart. Vaccine will be administrated on the fourth day (D4) of that week.
