PROPOSED MECHANISM OF ACTION

Uplizna™ (inebilizumab-cdon) is engineered for efficient B-cell depletion

  • Inebilizumab-cdon is a CD19+ B cell-directed humanized immunoglobulin G1 (IgG1) monoclonal antibody¹
  • Following cell surface binding to CD19+ B lymphocytes, inebilizumab-cdon results in antibody-dependent cellular cytolysis (ADCC)1-4

CD19 is a cell surface antigen present on pre-B and mature B lymphocytes1,4

CD19 expression across lymphocyte maturation CD19 expression across lymphocyte maturation
  • The precise mechanism by which inebilizumab-cdon exerts a therapeutic effect in neuromyelitis optica spectrum disorder (NMOSD) is unknown¹

B-cell depletion through the randomized-controlled period of the pivotal trial

  • B-cell counts were reduced below the lower limit of normal by four weeks in 100% of patients treated with Uplizna and remained below the lower limit of normal in 94% of patients for 28 weeks after initiation of treatment1,5
