Multicentric Castleman disease

This phase 2 trial tests the drug daratumumab in 28 adults with three rare and aggressive blood cancers: primary effusion lymphoma, plasmablastic lymphoma, and multicentric Castleman disease. Participants must have failed standard therapy or be unable to receive it. Daratumumab i…

This study tests a drug called pacritinib in people with HIV who have two rare conditions caused by the Kaposi sarcoma herpesvirus (KSHV): KSHV-associated multicentric Castleman disease (MCD) and KSHV inflammatory cytokine syndrome (KICS). These conditions cause severe, life-thre…

This study tests new diagnostic approaches for lymphoma and multicentric Castleman disease in people living with HIV who have swollen lymph nodes. Researchers will compare standard biopsies with fine needle aspiration and a new nucleic acid amplification device called TINY. The g…

This study collects blood, bone marrow, and tissue samples from people with HIV, KSHV, or certain cancers to help researchers learn more about these diseases. Participants must be 18 or older and may have HIV, KSHV, or related conditions. No treatment is given; the goal is to gat…

This study collects tissue and blood samples from adults with HIV, other immune disorders, or cancers thought to be caused by viruses. Researchers will compare genes in cancer tissue to normal tissue to find genetic changes that drive these cancers. The goal is to better understa…

This study follows 195 adults with KSHV-associated multicentric Castleman's disease (MCD) to better understand how the disease progresses and responds to treatments. Participants receive standard care and regular check-ups over several years. The goal is to improve future treatme…

This study collects blood and tissue samples from 200 adults with HIV and certain cancers (like Kaposi sarcoma, lymphoma, or anal cancer) to help researchers understand how HIV and cancer are connected. Participants donate samples, which are stored for future research. There is n…
