Objective: To learn if giving PDS01ADC alone or with M7824 could help the immune system fight KS tumors. Eligibility: People 18 and older with KS that has been treated with chemotherapy or immunotherapy Design: Participants will be screened with some or all of the following: medical history physical exam chest X-ray computed tomography scan blood and urine tests electrocardiogram and echocardiogram skin KS lesion biopsy lung exam gastrointestinal exam All participants will get PDS01ADC every 4 weeks for up to 96 weeks (or 24cycles). It is injected under the skin. Some participants will also get M7824 every 2 weeks for up to 96 weeks (or 24cycles). It is given through a plastic tube that is put in an arm vein.
