Siltuximab (INN[4]), sold under the brand name Sylvant, is used for the treatment of people with multicentric Castleman's disease.[2][3] It is a chimeric (made from human and mouse proteins) monoclonal antibody that binds to interleukin-6. It is an interleukin-6 (IL-6) antagonist.[2]
The common adverse reactions include pruritus, increased weight, rash, hyperuricemia, and upper respiratory tract infection.[5]
In April 2014, siltuximab was approved for medical use in the United States for the treatment of people with multicentric Castleman's disease who do not have human immunodeficiency virus (HIV) or human herpesvirus-8 (HHV-8).[5][6]
