The Clinical Safety and Efficacy of Targeted PD-L1 Therapy with Durvalumab in Solid Tumors

Programmed cell death protein 1/programmed cell death ligand 1 (PD-1/PD-L1) checkpoint inhibitors have been on the front line of clinical revolution in which, the targeted PD-L1 therapy has obtained some success in patients with solid tumors. A large number of clinical trials revealed that both monotherapy and combination therapy of PD-L1 antibody significantly suppress some tumor growth and promote the survival of patients. At present, anti-PD-L1 treatment has been used as a portion of standard treatment for lung cancer, breast cancer, head and neck squamous cell carcinoma, and urothelial carcinoma. Although much evidence has demonstrated that PD-L1 antibody is safe in most patients, there are still some adverse reactions, such as pneumonitis, hepatitis, colitis, neurologic events and myocarditis. In this review, the clinical information, including the efficacy and safety of durvalumab in solid tumors, was enumerated and summarized at this stage to grasp the current application of targeted PD-L1 therapy and provide guidance for clinical application.
