PROPOSED MECHANISM OF ACTION

UPLIZNA IS A NEXT-GENERATION B-CELL-DEPLETING MONOTHERAPY INTELLIGENTLY DESIGNED FOR OPTIMIZED EFFICACY AND TOLERABILITY1-4

UPLIZNA Mechanism of Action graphicUPLIZNA Mechanism of Action graphic

UPLIZNA is the first and only FDA-approved monotherapy to target CD19+ B cells in adult patients with AQP4-IgG+ NMOSD1,9

Afucosylated design

Enables efficient binding of effector cells, which allows for enhanced B-cell depletion at a lower dose1,7,8,2

  • Achieved significant B-cell depletion vs placebo in 8 days with results maintained over 4+ years1,2,10
  • 89% of patients on UPLIZNA were attack free through 28 weeks of treatment, with reduction in attack risk sustained over 4+ years1,10

Humanized structure

Designed to improve tolerability and decrease immunogenicity1-4

  • Low infusion-related reactions similar to placebo (9% UPLIZNA vs 10% placebo in randomized controlled period)2
  • Low rates of treatment-emergent anti-UPLIZNA antibodies (5.6%)1
  • Similar adverse event rate compared to placebo1,2

Selectively targets CD19

Depletes the broad range of B cells central to NMOSD pathogenesis, including plasmablasts and plasma cells1,5,6

  • Simple twice-yearly dosing schedule after initial dose1
  • Monotherapy1
  • Following cell surface binding to CD19+ B lymphocytes, UPLIZNA results in antibody-dependent cellular cytolysis1a

aThe precise mechanism by which UPLIZNA exerts its therapeutic effects in NMOSD is unknown.1

AQP4, aquaporin-4; IgG+, immunoglobulin G positive; NMOSD, neuromyelitis optica spectrum disorder.

INDICATION AND IMPORTANT SAFETY INFORMATION

INDICATION

UPLIZNA (inebilizumab-cdon) is indicated for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adult patients who are anti-aquaporin-4 (AQP4) antibody positive.

IMPORTANT SAFETY INFORMATION

UPLIZNA is contraindicated in patients with:

  • A history of life-threatening infusion reaction to UPLIZNA
  • Active hepatitis B infection
  • Active or untreated latent tuberculosis

WARNINGS AND PRECAUTIONS

Infusion Reactions: UPLIZNA can cause infusion reactions, which can include headache, nausea, somnolence, dyspnea, fever, myalgia, rash, or other symptoms. Infusion reactions were most common with the first infusion but were also observed during subsequent infusions. Administer pre-medication with a corticosteroid, an antihistamine, and an anti-pyretic.

Infections: The most common infections reported by UPLIZNA-treated patients in the randomized and open-label periods included urinary tract infection (20%), nasopharyngitis (13%), upper respiratory tract infection (8%), and influenza (7%). Delay UPLIZNA administration in patients with an active infection until the infection is resolved.

Increased immunosuppressive effects are possible if combining UPLIZNA with another immunosuppressive therapy.

The risk of Hepatitis B Virus (HBV) reactivation has been observed with other B-cell-depleting antibodies. Perform HBV screening in all patients before initiation of treatment with UPLIZNA. Do not administer to patients with active hepatitis.

Although no confirmed cases of Progressive Multifocal Leukoencephalopathy (PML) were identified in UPLIZNA clinical trials, JC virus infection resulting in PML has been observed in patients treated with other B-cell-depleting antibodies and other therapies that affect immune competence. At the first sign or symptom suggestive of PML, withhold UPLIZNA and perform an appropriate diagnostic evaluation.

Patients should be evaluated for tuberculosis risk factors and tested for latent infection prior to initiating UPLIZNA.

Vaccination with live-attenuated or live vaccines is not recommended during treatment and after discontinuation, until B-cell repletion.

Reduction in Immunoglobulins: There may be a progressive and prolonged hypogammaglobulinemia or decline in the levels of total and individual immunoglobulins such as immunoglobulins G and M (IgG and IgM) with continued UPLIZNA treatment. Monitor the level of immunoglobulins at the beginning, during, and after discontinuation of treatment with UPLIZNA until B-cell repletion especially in patients with opportunistic or recurrent infections.

Fetal Risk: May cause fetal harm based on animal data. Advise females of reproductive potential of the potential risk to a fetus and to use an effective method of contraception during treatment and for 6 months after stopping UPLIZNA.

Adverse Reactions: The most common adverse reactions (at least 10% of patients treated with UPLIZNA and greater than placebo) were urinary tract infection and arthralgia.
