Premedication is not usually required in the first cycle. For subsequent cycles, adequate premedication may be administrated per local standard. OR * XELOX\*, IV, Q3W + Nivolumab (360 mg, IV, Q3W). XELOX = Oxaliplatin 130mg/m² IV on Day 1 of each treatment cycle + capecitabine 1000mg/m² orally twice daily on Days 1 to 14 of each treatment cycle, every 3 weeks * Treatment is recommended until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression.
Blood-brain barrier opening with concomitant BAL, BOT, DOXEXPERIMENTALPatients will undergo implantation of Sonocloud-9 after completion of radiotherapy. Within 21 days after implant, ultrasound-based BBB opening with concomitant administration of DOX (30 mg) + BAL (450 mg) every 3 weeks, and BOT (dose 1mg/kg) every 6 weeks will be initiated.

ZalifrelimabDRUGZalifrelimab (AGEN1884) is a fully human monoclonal immunoglobulin G1 κ subclass (IgG1κ) antibody that specifically recognizes cytotoxic T lymphocyte-associated protein 4 (CTLA-4, also known as CD152). Zalifrelimab (AGEN1884) is being developed as a monotherapy for cancer indications with potential for future development in combination with other immunotherapies.
DoxorubicinDRUGDoxorubicin is the standard of care first-line therapy for most subtypes of metastatic soft tissue sarcomas. Doxorubicin monotherapy administered at 75 mg/m2 has resulted in objective response rate of 14%, and median progression-free survival of 4.6 months, and another study reported progression-free survival at 6 months of 46.3%, with a median PFS of 5.8 months, and best objective response rate of 19%.
