Second-line Immunotherapy for ES-SCLC
Recruiting now · Not applicable
Conditions studied: Extensive Stage Small Cell Lung Cancer (ES-SCLC)
In brief
At present, the first-line standard treatment for patients with extensive-stage small cell lung cancer (ES-SCLC) is immunotherapy combined with chemotherapy. For patients who relapse within 6 months after first-line chemotherapy, conventionally recommended chemotherapy drugs include topotecan, irinotecan, gemcitabine, paclitaxel or vinorelbine, etc., but due to limited benefits to patients, patients are also recommended to participate in relevant clinical studies. New treatment methods are constantly being explored in second-line treatment, including fluzoparib combined with adebelimumab. The current status of second-line treatment is still worrying. Selinexor is a class of nuclear export selective inhibitors (SINEs) for the export protein receptor XPO1. PO1 promotes the transport of mRNA and cargo proteins, including tumor suppressor proteins (TSPs), hormone receptors (GRs), and immune response regulators. Selinexor covalently binds to the XPO1 protein, blocking the export of TSPs and GRs and accumulating them in the nucleus, preventing the translation of oncoprotein mRNA, stopping the cell cycle process, and initiating apoptosis. Multiple in vitro and in vivo studies have verified that selinexor combined with chemotherapy/radiotherapy/targeted therapy exhibits significant anti-tumor activity. This study plans to use selinexor combined with adebrelimab and albumin-paclitaxel as a second-line treatment for ES-SCLC to explore the efficacy and safety of this regimen.
