Axicabtagene ciloleucel is in clinical development as second-line treatment for adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). DLBCL is a cancer affecting a type of white blood cells called lymphocytes or B-cells. DLBCL is an aggressive cancer and although it can be cured in more than half of people affected, it remains a serious and life threatening disease. A relapse is when the lymphoma comes back after successful treatment and refractory means the lymphoma did not respond to the first course of treatment.
Axicabtagene ciloleucel contains the patient’s own T-cells (a type of white blood cell) that have been modified genetically in the laboratory so that they make a protein called chimeric antigen receptor (CAR). CAR can attach to another protein on the surface of cancer cells and kill the cancer cells. If licensed, axicabtagene ciloleucel will offer an additional second-line treatment option for adult patients with relapsed or refractory DLBCL.
Selpercatinib is in clinical development for the treatment of metastatic RET fusion-positive non-small cell lung cancer (NSCLC). NSCLC is the most common type of lung cancer and at the metastatic stage the disease has already spread from the lungs to other sites. Around 2% of these patients will have tumours that contain fusion mutations in the RET gene. Cells in these tumour produce altered RET signalling receptors that allow uncontrolled cancer growth. Currently the only treatment options that attempt to inhibit RET fusion-positive tumour activity are nonselective multikinase inhibitors.
