Durvalumab Combined With Chemoradiotherapy for Limited Stage Small Cell Lung Cancer (Camel-01)

Durvalumab is an immunoglobulin G (IgG) 1-κsubtype monoclonal antibody (mAb) that blocks the interaction of PD-L1 with PD-1 in T cells and CD80 (B7.1) in immune cells (ics). Durvalumab is developed by Astrazeneca /MedImmune for the treatment of cancer. Durvalumab is designed to reduce the cytotoxicity of antibody-dependent cells and complement dependent cytotoxicity. In vitro studies have demonstrated that Durvalumab can antagonize the inhibition of PD-L1 in human primary T cells, causing them to resume proliferation and release interferon gamma (IFNγ). To date, more than 1,800 patients have been treated with valiuzumab as a single agent or in combination with other cancer agents as part of ongoing studies. Durvalumab: 10mg/Kg, intravenously, starting at week 7 every 3 weeks for at least 1 year, or until progression, intolerance, or spontaneous withdrawal of the patient.

"Etoposide: 80-100mg/m², intravenous infusion, given at week 1, 4, 7, 10, 13, 16, a total of 6 cycles.~Carboplatin: AUC=5-6, intravenous infusion, given at weeks 1, 4, 7, 10, 13, 16, a total of 6 weeks. Or cisplatin: 75-80mg/m2 intravenously, given at weeks 1, 4, 7, 10, 13, 16 for a total of 6 weeks."
