About
The investigators hypothesize that zanzalintinib in combination with ipilimumab and nivolumab will be well tolerated and serve as a potential therapeutic strategy in metastatic soft tissue sarcoma (mSTS) including myxofibrosarcoma, undifferentiated pleomorphic sarcoma, dedifferentiated liposarcoma, cutaneous angiosarcoma, and undifferentiated sarcoma histologies.
