Condition: Soft Tissue Sarcoma · Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University
Soft tissue sarcoma (STS) is a rare, highly heterogeneous malignancy with a poor prognosis. The standard first-line treatment for advanced patients is anthracyclines (doxorubicin, A) combined with ifosfamide (I, AI regimen), but the efficacy is limited, and some subtypes do not respond well. Immune checkpoint inhibitors (ICI) have shown potential in specific STS subtypes. Anthracyclines can induce immunogenic cell death and upregulate PD-L1, providing a theoretical basis for combined immunotherapy. Previous studies have shown that ICI combined with chemotherapy (such as pembrolizumab + doxorubicin) is more effective than chemotherapy alone. Envolizumab is the world's first subcutaneously injected PD-L1 single-domain antibody-Fc fusion protein, with significant advantages: (1) small molecular weight (\~80kDa) and strong tissue penetration; (2) high stability and can be stored at room temperature; (3) convenient subcutaneous injection and good tolerability (Phase II study of MSI-H/dMMR solid tumors ORR 42.7%, grade 3-4 TEAE 15.5%). In 2022, the FDA granted orphan drug designation for the treatment of STS. This study aims to evaluate the efficacy (ORR, PFS, OS, etc.) and safety of Envolizumab combined with an AI regimen (doxorubicin + ifosfamide) as a first-line treatment for advanced STS.
