Surufatinib and Envafolimab as Second or More-line Therapy in Advanced Soft Tissue Sarcoma Patients
Study Details
Study Description
Brief Summary
In this study, we investigated the efficacy and safty of surufatinib combined with envafolimab followed by surufatinib as second or more - line therapy in advanced soft tissue sarcoma patients. Patients who have failed at least the first-line therapy and have progressive disease or cannot tolerate within 6 months before enrollment will be treated with surufatinib combined with envafolimab.

Outcome Measures
Primary Outcome Measures
- Objective Response Rate (ORR) [It will be evaluated at about 18 weeks]
Assess ORR, defined as Investigator-assessed CR+PR, per RECIST 1.1.
Secondary Outcome Measures
- Progression-Free Survival (PFS) [From the start of randomization to a minimum of 42 months]
PFS is defined as time (in months) from date of randomization to the date of the first documentation of objective progressive disease (PD) or death due to any cause in the absence of documented PD (whichever occurs first). PFS will be determined according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) based on investigator response assessment.
- Disease Control Rate (DCR) [From the start of randomization to a minimum of 42 months]
Percentage of patients with CR/PR/SD in the number of patients that whose tumour can be evaluated.
- Overall Survival (OS) [From the start of randomization to a minimum of 42 months]
OS is defined as the time (in months) from randomization to the date of death, regardless of the actual cause of the subject's death.
- Number of Subjects With Treatment-Emergent Adverse Events (TEAEs) According to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0 [From the start of randomization to a minimum of 42 months]
TEAEs will be defined as the adverse events (AEs) that occur between first dose of study drug administration and 28 days after the last dose of study drug administration that were absent before treatment or that worsened relative to pretreatment state.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male or female subjects aged from 18 to 75 years old;
-
Subjects with histologically confirmed unresectable locally advanced or metastatic soft tissue sarcoma, which includes synoviosarcoma, leiomyosarcoma, undifferentiated pleomorphic sarcoma/malignant fibrous histiocytoma, fibrosarcoma, epithelioid sarcoma, angiosarcoma, alveolar soft-part sarcoma, etc. Chondrosarcoma, osteosarcoma, dermatofibrosarcoma protuberans, gastrointestinal stromal tumor and malignant mesothelioma are excluded;
-
Patients who have at least failed first-line treatment and had a disease progression within 6 months or can not tolerate the treatment. Notes: if the cumulative dose of anthracycline drugs reach threshold according to the guideline of Chinese Society of Clinical Oncology(CSCO) published in 2020, it will be regarded as intolerable;
-
Disease must be measurable by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). Previously irradiated focus can be considered as measurable only if there is definite progress after radiotherapy;
-
Newly obtained or archived tumor tissue samples can be provided;
-
Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 to 2 at trial entry;
-
Estimated life expectancy of more than 12 weeks;
-
Adequate organ functions defined by the protocol;
-
Negative blood pregnancy test at Screening for women of childbearing potential within 1 week before the first medication; Highly effective contraception for both male and female subjects if the risk of conception exists;
-
Able to comply with the research protocol and follow-up process for treatment and follow-up;
-
Already signed an informed consent form
Exclusion Criteria:
-
Patients whose tumors are judged by the investigators to be at high risk of invading vital blood vessels and causing fatal hemorrhage during the study.
-
Occurrence of arterial/venous thrombotic events within 6 months before treatment, such as cerebrovascular accident (including transient ischemic attack, hematencephalon and cerebral infarction), deep vein thrombosis , pulmonary embolism, etc.
-
Occurrence of clinically significant hemoptysis(>5ml fresh blood in 4 weeks), hemorrhagic tendency(bleeding>30ml within 3 months), such as gastrointestinal bleeding, hemorrhagic gastric ulcer, fecal occult blood test(FOBT) ++ in the baseline period , or vasculitis, etc;
-
Hypertension that cannot be controlled stably by drugs, which is defined as: systolic blood pressure>140mmHg or diastolic blood pressure>90mmHg;
-

-
Abnormal coagulation function (INR>1.5 or PT>ULN+4s or APTT >1.5 ULN), hemorrhagic tendency or being treated with thrombolysis or anticoagulation therapy. Notes: on the premise of INR ≤ 1.5, it is allowed to use low-dose heparin (daily dosage of adults is 6000-12000U) or low-dose aspirin (daily dosage ≤ 100mg) for preventive purposes;
-

-

Corticosteroids can be used to deal with adverse reactions (AEs) and serious adverse reactions (SAEs) after period 1, and can also be used as a pre-medication for the control chemotherapy group, as a preventive drug for the allergy/reaction of intravenous contrast enhanced radiography, or if it is considered necessary for the subject to use. b. Except for the subjects who are receiving steroid replacement therapy every day. A daily dose of 5-7.5 mg of prednisone is an alternative treatment.
- Equivalent dose of hydrocortisone treatment can also be allowed to enter the trial if it is an alternative treatment.
-

History of allergy to any component of surufatinib and envafolimab;
-
Accination with live or live/attenuated viruses within 4 weeks of the first dose of surufatinib/ envafolimab and while on trial is prohibited;
-
