Overcoming osteosarcoma immunotherapy resistance by tumour-localised IL-12 driven anti-tumour immunity.
BACKGROUND TO THE RESEARCH PROJECT
Despite optimal management of localised osteosarcoma disease, over 50% of patients develop metastatic disease or recurrence, which lead to poor survival outcomes in approximately 19 months. Immunotherapies, activating immune cells to attack cancers, became standard therapy in many other cancer types and enabled prolonged effects including prevention of recurrence and metastasis. However, osteosarcoma responds poorly to current standard immunotherapies due to A) inactivation of the immune system, B) resistance to immunotherapy, and C) difficulty in locally delivering drugs to tumour sites. Immunotherapies can achieve long-term effects including prevention of metastasis and recurrence. There remains huge room for improvement for immunotherapy in osteosarcoma as many patients suffer due to lack of treatment options and recurrence/metastasis.
