SFRT+Sequential Hypofractionated/Conventional Fractionated RT+Iparomlimab and Tuvonralimab for Relapsed/Refractory Solid Tumors

Summary

Study Objectives Primary Objective:To evaluate the safety of SFRT followed by hypofractionated/conventional fractionated radiotherapy combined with Iparomlimab and Tuvonralimab Injection in relapsed/refractory bulky solid tumors. Secondary Objectives:To assess efficacy (objective response rate, disease control rate, progression-free survival, etc.) and identify predictive biomarkers.To explore correlations between immunologic biomarkers (e.g., PD-L1 expression, plasma IL-2/IL-10) and treatment outcomes. Study Endpoints Primary: Safety (incidence/severity of treatment-related adverse events). Secondary: ORR, DCR, DoR, mPFS, mOS Exploratory: Biomarker analysis (PD-L1, IL-2, IL-10).
