About this trial
This study intends to enroll patients with advanced soft tissue sarcoma, employing immunotherapy combined with eribulin, anlotinib, and radiotherapy as subsequent-line treatment to preliminarily explore its efficacy and safety. QL1706, a dual-targeting agent against PD-1 and CTLA-4, has been approved by the National Medical Products Administration (NMPA) of China for the second-line treatment of cervical cancer.

Treatments tested in this trial
QL1706 + Eribulin + Anlotinib + Radiotherapy
DrugQL1706: 5 mg/kg, intravenous injection (IV) on Day 1, every 3 weeks (Q3W). Eribulin : 1.1 mg/m², intravenous infusion (IV) on Days 1 and 8, Q3W. Anlotinib : Oral administration before breakfast, 12 mg once daily (QD) on Days 1-14, followed by a 1-week drug holiday, Q3W. Radiotherapy : Hypofractionated radiotherapy, 15-60 Gy delivered in 5-8 fractions. Eribulin is administered for 6 cycles. Epalizumab and anlotinib are continued until disease progression, intolerable toxicity, initiation of new anti-tumor treatment, loss to follow-up, death, or withdrawal from the study (whichever occurs first).
