Brief Summary

This clinical trial aims to evaluate the efficacy and safety of Iparomlimab and Tuvonralimab (QL1706), a dual-targeting immunotherapy (anti-PD-1/CTLA-4), in patients with intermediate trophoblastic tumors (ITT). The main questions it aims to answer are: Does QL1706 improve complete response (CR) rates (primary endpoint) and survival outcomes? What are the safety profiles of QL1706 in ITT, including immune-related adverse events? Participants will receive QL1706 (5 mg/kg IV, Q3W) ± chemotherapy (FAEV/EMA/EP/EMA/CO/TP-TE). They will also receive Maintenance therapy post-hCG normalization. Efficacy is assessed via serial β-hCG tests, imaging (every 9-12 weeks), and biomarker analysis.
