WEP Clinical (WEP) today announced a partnership with Horizon Therapeutics plc (Horizon) to make a Named Patient Use (NPU) Program available for UPLIZNA. The UPLIZNA NPU Program is for adult patients who are AQP4-IgG+ NMOSD living in countries where UPLIZNA is not approved by the country’s local regulatory authority.

The UPLIZNA NPU Program is designed to provide an avenue for physicians – contingent on meeting eligibility criteria and receiving local health approval – to potentially prescribe UPLIZNA on behalf of patients who live in certain countries where it is not available. UPLIZNA is currently approved in the United States, Japan and South Korea for the treatment of adults with AQP4-IgG+ NMOSD. In Japan and South Korea, UPLIZNA is marketed by Mitsubishi Tanabe Pharma Corporation.

Through the NPU Program, WEP and Horizon will work together to enable health care providers to access UPLIZNA for adults who meet the eligibility criteria. Health care professionals can inquire for more details about UPLIZNA and the NPU Program by emailing WEP at NMOSD@wepclinical.com.

NMOSD is a unifying term for neuromyelitis optica (NMO) and related syndromes. NMOSD is a rare, severe, relapsing, neuroinflammatory autoimmune disease that attacks the optic nerve, spinal cord and brain stem.1,2 Approximately 80% of all patients with NMOSD test positive for anti-AQP4 antibodies.3

This is the second NPU Program WEP has been awarded by Horizon, after initiating a program for Thyroid Eye Disease (TED) drug, Tepezza (TEPROTUMUMAB-TRBW), in May 2021.

 Jas Khera, Managing Director of WEP, said:

“We are excited to be working on yet another program with the Horizon team to help make a much-needed drug available to patients living in countries where it is not approved. Providing access to UPLIZNA is in line with WEP’s mission to support patients suffering from rare and debilitating conditions around the world, and being awarded this second contract with Horizon is testament to our ability to run safe and efficient access programs that meet sponsor needs and expectations.

Forward Looking Statements

These forward-looking statements are based on Horizon’s current expectations and inherently involve significant risks and uncertainties. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation, the risk of future supply disruptions; impacts of the COVID-19 pandemic and actions taken to slow its spread; regulatory obligations and oversight, including any changes in the legal and regulatory environment in which Horizon operates and those risks detailed from time-to-time under the caption “Risk Factors” and elsewhere in Horizon’s filings and reports with the SEC.

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.


UPLIZNA is contraindicated in patients with:

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


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.
