To Evaluate the Single-arm, Multi-center Phase II Clinical Trial of Benmelstobart Injection Combined With Anlotinib Hydrochloride Capsules in the Treatment of Advanced or Unresectable Alveolar Soft Part Sarcoma
This is a Phase II, single-arm, multicenter clinical study aimed at demonstrating the effectiveness of benmelstobart injection combined with anlotinib hydrochloride capsules in patients aged 14 years or older with advanced or unresectable alveolar soft part sarcoma by evaluating the objective response rate (IRC).
• Only when all the following criteria are met will the subjects be eligible for inclusion in this study:
‣ The subjects voluntarily join this study, sign the informed consent form, and have good compliance;
⁃ ≥14 years old (calculated from the date of signing the informed consent form);
⁃ Eastern Cooperative Oncology Group Performance Status (ECOG) score of 0 to 1;
⁃ Expected survival greater than 12 weeks;
⁃ Pathologically confirmed recurrent and/or metastatic or unresectable alveolar soft part sarcoma, without previous systemic treatment;
⁃ Confirmed to have at least one measurable lesion according to RECIST 1.1;
⁃ Laboratory tests meet the following standards:
• Hemoglobin (HGB) ≥ 90g/L;
∙ Absolute neutrophil count (NEUT) ≥ 1.5×109/L;
∙ Platelet count (PLT) ≥ 100×109/L.
∙ Total bilirubin (TBIL) ≤ 1.5 times the upper limit of normal (ULN);
∙ Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 ULN. If there is liver metastasis, ALT and AST ≤ 5 ULN;
∙ Serum creatinine (CR) ≤ 1.5 ULN or creatinine clearance rate (CCR) ≥ 60ml/min;
∙ Prothrombin time (PT), activated partial thromboplastin time (APTT), and international normalized ratio (INR) ≤ 1.5×ULN (if not receiving anticoagulant therapy);
∙ Thyroid stimulating hormone (TSH) ≤ ULN; if abnormal, T3 and T4 levels should be examined. If T3 and T4 levels are normal, the subject can be included.
⁃ Women of childbearing age must agree to use effective contraceptive measures during the study and for 6 months after the study, and have a negative serum test within 7 days before study enrollment; men must agree to use effective contraceptive measures during the study and for 6 months after the study.
