Overview
Brief Summary
This is a prospective, single-center, single-arm, phase Ib/II clinical trial. The study aims to evaluate the safety and efficacy of the treatment which combines radiotherapy, Sintilimab (Anti-PD1 Antibody) and Surufatinib (small-molecule Tyrosine Kinase inhibitor) in patients with high-risk localized soft tissue sarcoma.
There will be 52 patients with high-risk localized extremity and trunck soft tissue sarcoma recruited. The trail is designed as a two-stage study. In safety lead-in phase (phase Ib), using 3+3 design, 6 cycles of Surufatinib (250mg, 200mg, qd) and Sintilimab (200mg, q3w) will be applied. And radiotherapy (BED=50-60Gy (α/β=10)) will begin in week 4 of the therapy. In extended phase (phase II), Surufatinib will be applied in the recommended phase 2 dose (RP2D) according to phase Ib. And 200mg Sintilimab and radiotherapy will be applied as before. The dose-limiting toxicity (DLT) in phase Ib and objective response rate (ORR) in phase Ib+Phase II will be mainly analyzed.

Arms & Interventions
Treatment Arm
There will be 52 patients with high-risk localized extremity and truncal soft tissue sarcoma recruited. In safety lead-in phase (phase Ib): using 3+3 design, patients will receive 6 cycles of Surufatinib in three different dosages and Sintilimab. And radiotherapy will begin in week 4. In extended phase (phase II): Surufatinib in RP2D, Sintilimab and radiotherapy will be applied as before.
Intervention: Sintilimab

Outcomes
Primary Outcomes
Objective Response Rate (ORR)
Time Frame: The objective response rate (ORR) will be evaluated before surgery.
The percentage of patients with objective response. Objective response is defined as complete response (CR) or partial response (PR) per response evaluation criteria (RECIST v1.1) before surgery.
Secondary Outcomes
- Wound Complications(Up to 120 days from the surgery.)
- Local Control Rate(From the start of treatment to local recurrence, up to 5 years.)
- Quality of Life (QoL) according to the Musculoskeletal Tumor Society (MSTS)(Quality of Life (QoL) will be evaluated at least five times: before treatment, at 3, 6, 12 and 24 months respectively after surgery.)
- Quality of Life (QoL) according to the Short Form (SF)-36 questionnaires(Quality of Life (QoL) will be evaluated at least five times: before treatment, at 3, 6, 12 and 24 months respectively after surgery.)
- Non-Perfused Volume (NPV)(The non-perfused volume (NPV) will be measured in four weeks before preoperative treatment and before surgery in week18-21.)
- Adverse Events(From the beginning of treatment to 90 days after the end of the last treatment.)
- Quality of Life (QoL) according to the Toronto Extremity Salvage Score (TESS)(Quality of Life (QoL) will be evaluated at least five times: before treatment, at 3, 6, 12 and 24 months respectively after surgery.)
- Pathological Complete Response (pCR) and Near pCR Rate(The pathologic complete response (pCR) rate will be evaluated from surgical samples, immediately after surgery.)
