What the trial is, and whether it could suit you
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, chemotherapy and immunotherapy in patients with high-risk localized soft tissue sarcoma.
There will be 52 patients with high-risk localized extremity and trunk soft tissue sarcoma recruited. The trail is designed as a two-stage study. In safety lead-in phase (phase Ib), using 3+3 design, 4 cycles of Pegylated Liposomal Doxorubicin (37.5 mg/m2, 30 mg/m2, q3w) or doxorubicin hydrochloride (75mg/m2, q3w), Sintilimab (200mg, q3w) and radiotherapy (BED=50-60Gy (α/β=10)) will be applied. In phase II, Pegylated Liposomal Doxorubicin will be applied in the recommended phase 2 dose (RP2D) according to phase Ib. And 200mg sintilimab and radiotherapy will be applied as before.
