Summary

Background:

Kaposi sarcoma (KS) tumors grow on the skin, lymph nodes, lungs, bone, and gastrointestinal tract. KS often affects people with immune deficiencies, such as among people living with HIV or those with prior history of transplant. Researchers want to see if 2 non-chemotherapy drugs can help people with KS. PDS01ADC triggers the immune system to fight tumors. M7824 blocks the pathways that cancer cells use to stop the immune system from fighting tumors.

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.

Participants will complete questionnaires about how KS affects their quality of life. Their KS lesions will be measured and photographed. They will repeat some of the screening tests. They will give saliva samples or additional tissue samples. They will have a lung function test. Their ability to perform their normal activities will be assessed. The treatment duration is up to 96 weeks (or 24cycles) with an option to take PDS01ADC and/or M7824 until the KS tumors are not responding, or you develop unacceptable side effects.

Participants will have follow-up visits 7 and 30 days after treatment ends, then every 3 to 6 months for the next 18 months, then once a year for 3 years.
