The FDA granted orphan drug designation to serplulimab for treatment of small cell lung cancer.
Serplulimab (Hansizhuang, Shanghai Henlius Biotech) is a PD-1 inhibitor in development for first-line treatment of small cell lung cancer.
Small cell lung cancer — the most aggressive lung cancer subtype — accounts for an estimated 15% to 20% of lung cancer cases worldwide. It typically is associated with rapid disease progression, early metastasis and poor prognosis.
Standard treatment for limited-stage small cell lung cancer consists of surgery, chemotherapy and concurrent radiotherapy.
