UPLIZNA

INEBILIZUMAB-CDON CD19-directed Antibody Interactions
Approved 2020-06-11

UPLIZNA (inebilizumab-cdon) is a CD19-directed cytolytic antibody indicated for the treatment of specific autoimmune disorders in adult patients. It is used to treat neuromyelitis optica spectrum disorder (NMOSD) in patients who are anti-aquaporin-4 (AQP4) antibody positive and generalized myasthenia gravis (gMG) in patients who are anti-acetylcholine receptor (AChR) or anti-muscle specific tyrosine kinase (MuSK) antibody positive. The medication is also indicated for the treatment of adults with Immunoglobulin G4-related disease (IgG4-RD).

How UPLIZNA Works

Inebilizumab-cdon functions by binding to CD19, a cell surface antigen present on pre-B and mature B lymphocytes. Once the drug binds to these B lymphocytes, it induces antibody-dependent cellular cytolysis. This mechanism is presumed to provide therapeutic effects across its approved indications by targeting and depleting these specific immune cell populations.

What UPLIZNA Treats

3 indications

UPLIZNA is approved for 3 conditions since its original approval in 2020. These indications span multiple therapeutic areas including oncology, immunology, and more.

  • Neuromyelitis optica spectrum disorder (NMOSD) in anti-aquaporin-4 (AQP4) antibody positive adults
  • Immunoglobulin G4-related disease (IgG4-RD) in adults
  • Generalized myasthenia gravis (gMG) in anti-acetylcholine receptor (AChR) or anti-muscle specific tyrosine kinase (MuSK) antibody positive adults

UPLIZNA Target & Pathway

Pro

Target

CD19 (B-Lymphocyte Antigen CD19) Cell Surface Marker

A protein expressed on B-cells throughout their development. CD19 is a key target for CAR-T cell therapies in B-cell leukemias and lymphomas, where engineered T-cells are directed to kill CD19-expressing cancer cells.

UPLIZNA Competitors

Pro

3 other drugs also target CD19. Compare mechanisms, indications, and trial activity.

Drug = Competitor name Company = Manufacturer N indic. = FDA-approved indications → Date = Patent/exclusivity expiry

Competitors share the same molecular target (CD19). Earlier expiry dates signal biosimilar/generic opportunities.
