A Personalized NeoAntigen Cancer Vaccine Combined With Anti-PD-1 in Melanoma
Study Purpose
This study assessed the safety and efficacy of individualized new antigen cancer vaccine combined with Programmed Cell Death Protein 1(PD1) inhibitor Toripalimab in the treatment of metastatic cutaneous melanoma. Melanoma is the most malignant skin neoplasm. Immunotherapy is the main treatment at present. PD1 is an immunological checkpoint and the inhibitors can reduce the immune escape of tumors, enhance T cell function and kill tumors. At present, PD1 antibody is the representative drug of immunotherapy, but the overall efficiency of its single drug treatment of acral melanoma is still low, and the combined treatment can significantly improve the efficiency. Melanoma has a high mutation load, which makes each patient have mutations specific to individual patients and tumors (changes in genetic material). These mutations lead to tumour cells producing proteins that are distinct from those of the body's own cells. These proteins used in vaccines may cause a strong immune response, which may help participants' bodies fight against any cancer cells that may lead to future recurrence of melanoma. Inhibition of PD1 can enhance the activity of T cells and form T cells with sustained killing activity. Tumor vaccines activate human Antigen Presenting Cells (APC) by injecting tumor antigens and adjuvants, and then activate T cells by APC to produce specific killing T cells. Therefore, the combination of "tumor vaccine + PD1 inhibitor" can produce effective specific killing and sustained activation of T cells, and prevent the establishment of inhibitory tumor microenvironment by tumor cells. The study will examine the safety and efficiency of the combined therapy at different time points and assess whether there is an immune response in the patient's peripheral blood and tumor tissue.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial Details
Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT04072900 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
