X-linked Lymphoproliferative Syndrome Type 2 (XLP-2) Clinical Trial
Official title:
A Single-patient Clinical Trial of MAS825 in a Patient With XIAP Deficiency
MAS825 is a bi-specific IgG1 monoclonal antibody that simultaneously targets IL-1 beta and IL-18, thereby neutralizing both cytokines that are thought to be integral to the pathogenesis of XLP-2. Clinical trials are currently examining its efficacy in other diseases associated with elevations of these cytokines, including NLRC4-associated disease and hidradenitis suppurativa. This study proposes to assess the effectiveness of MAS825 in a single patient with XLP-2, who has previously demonstrated response to blockade of IL-1 beta and IL-18. Given the lack of alternative pharmaceutical options for XLP-2, this represents the only known medication option that avoids the toxicity associated with high-dose corticosteroids and the morbidity associated with hematopoietic stem cell transplantation.
