Neoantigen-loaded DC Vaccine and Conventional Third-line Therapy for CRC Progressed After Second-line Treatment

Conventional third-line therapy includes oral chemotherapy drugs and/or targeted cancer drugs. The medication, dosage and treatment cycle of oral chemotherapy drugs and/or targeted cancer drugs will be determined by the subject's attending physician based on the subject's specific circumstances.

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.
