Официальное название

A Multicenter, Single-arm, Prospective Phase II Clinical Study of Epalrotokewali Monotherapy Combined With Eribulin, Anlotinib, and Radiotherapy for the Treatment of Patients With Advanced Soft Tissue Sarcoma.

Обзор

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.

Вмешательства

• Препарат QL1706 + Eribulin + Anlotinib + Radiotherapy
  QL1706: 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

• Subjects aged 14-75 years;
• Patients with histologically or cytologically confirmed advanced soft tissue sarcoma (STS);
• Patients with STS who have failed first-line or higher treatment;
• At least one measurable lesion per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1);
• ECOG performance status (PS) score of 0-1;
• Adequate organ and bone marrow function, with laboratory tests meeting the following criteria within 7 days prior to the first dose of study drug (without having received any blood components, hematopoietic growth factors, albumin, or other medications considered corrective therapy by the investigator within 14 days prior to testing):

i. Hematology: Hemoglobin (Hb) ≥90 g/L, absolute neutrophil count (ANC) ≥1.5×10⁹/L, platelet count (PLT) ≥90×10⁹/L.

ii. Biochemistry: Serum creatinine (Cr) ≤1.5×upper limit of normal (ULN); serum total bilirubin (TBIL) ≤1.5×ULN; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0×ULN for subjects without liver metastases, and ALT and AST ≤5.0×ULN for subjects with liver metastases; serum albumin (ALB) ≥25 g/L.

iii. Coagulation function: International normalized ratio (INR) ≤1.5×ULN; prothrombin time (PT) and activated partial thromboplastin time (APTT) ≤1.5×ULN (for subjects receiving prophylactic anticoagulation therapy, the investigator should assess that INR and APTT are within safe and effective therapeutic ranges);

Men must agree to use appropriate contraception or have undergone surgical sterilization from screening until 3 months after discontinuation of trial medication;
• Expected survival time ≥12 weeks.
