EUSA Pharma (UK) Limited ("EUSA Pharma"), a global biopharmaceutical company focused on oncology and rare diseases, announced that the National Comprehensive Cancer Network® (NCCN®) has updated their Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for B-Cell Lymphomas to include siltuximab (SYLVANT®) as the preferred primary treatment for patients with human immunodeficiency virus–negative [HIV(-)] and human herpesvirus 8–negative [HHV-8(-)] multicentric Castleman disease (MCD), also known as idiopathic multicentric Castleman disease (iMCD), regardless of histopathologic subtype.1 Siltuximab is currently approved in more than 40 countries worldwide for the treatment of all histopathologic subtypes of iMCD, a rare, life-threatening and debilitating orphan condition of the lymph nodes and related tissues. 2,3 The update is based on a 2020 publication which demonstrated that there is insufficient evidence to guide treatment based solely on lymph node histopathologic subtype.4
Lee Morley, Chief Executive Officer, EUSA Pharma, said, "We are delighted that the NCCN has recognised the importance of siltuximab in treating iMCD. As the only FDA-approved therapy indicated for this patient population, the change in the NCCN Guidelines® means that even more patients will be able to benefit."
Dr David Fajgenbaum, MD, MBA, MSc, Assistant Professor of Medicine, Translational Medicine & Human Genetics, University of Pennsylvania and Co-Founder & Executive Director, Castleman Disease Collaborative Network (CDCN) said, "As a patient with iMCD and a researcher focused on advancing effective treatments for iMCD, I am really pleased to see that the NCCN has updated their iMCD treatment Guidelines to align with FDA and EC approvals and evidence-based recommendations from the Castleman Disease Collaborative Network. This is a significant step forward, but we have important work ahead to ensure that all iMCD patients are able to receive treatments that help them to live full lives after their diagnosis."
Siltuximab is a monoclonal antibody that directly neutralises IL-6, an inflammatory cytokine detected at elevated levels in multiple inflammatory conditions. SYLVANT® (siltuximab) is currently approved by the US Food and Drug Administration (FDA) and the European Commission (EC), as well as regulatory authorities in several other jurisdictions worldwide, for the treatment of adult patients with multicentric Castleman disease (MCD) who are human immunodeficiency virus (HIV) negative and human herpesvirus-8 (HHV-8) negative. Indications and Usage – See EMA Summary of Product Characteristics (SmPC) and FDA Prescribing Information or additional information.
