Hepatitis B Virus Screening

Prior to initiating UPLIZNA, perform Hepatitis B virus (HBV) screening. UPLIZNA is contraindicated in patients with active HBV confirmed by positive results for surface antigen [HBsAg] and anti-HBV tests. For patients who are negative for HBsAg and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult liver disease experts before starting and during treatment with UPLIZNA [see Contraindications (4) and Warnings and Precautions (5.2)].

Serum Immunoglobulins

Prior to initiating UPLIZNA, perform testing for quantitative serum immunoglobulins. For patients with low serum immunoglobulins, consult immunology experts before initiating treatment with UPLIZNA [see Warnings and Precautions (5.3)].

Tuberculosis Screening

Prior to initiating UPLIZNA, evaluate for active tuberculosis and test for latent infection. For patients with active tuberculosis or positive tuberculosis screening without a history of appropriate treatment, consult infectious disease experts before initiating treatment with UPLIZNA [see Contraindications (4) and Warnings and Precautions (5.2)].

Vaccinations

Because vaccination with live-attenuated or live vaccines is not recommended during treatment and after discontinuation until B-cell repletion, administer all immunizations according to immunization guidelines at least 4 weeks prior to initiation of UPLIZNA for live or live-attenuated vaccines [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2)].

Infection Assessment

Prior to every infusion of UPLIZNA, determine whether there is an active infection. In case of active infection, delay infusion of UPLIZNA until the infection resolves [see Warnings and Precautions (5.2)].

Premedication

Table 1 shows premedication to administer prior to each infusion of UPLIZNA to reduce the frequency and severity of infusion reactions [see Warnings and Precautions (5.1)].

NMOSD and IgG4-RD

UPLIZNA is administered as an intravenous infusion (see Table 2). The recommended dosage is:

• Initial dose: 300 mg intravenous infusion followed 2 weeks later by a second 300 mg intravenous infusion.
• Subsequent doses (starting 6 months from the first infusion): single 300 mg intravenous infusion every 6 months.

Administration

UPLIZNA must be diluted prior to administration [see Dosage and Administration (2.4)].

Prior to the start of the intravenous infusion, the prepared infusion solution should be at room temperature.

Administer UPLIZNA under the close supervision of an experienced healthcare professional with access to appropriate medical support to manage potential severe reactions such as serious infusion reactions [see Warnings and Precautions (5.1)].

Administer the prepared solution intravenously via an infusion pump at an increasing rate to completion, approximately 90 minutes, according to the schedule in Table 2. Administer through an intravenous line containing a sterile, low-protein binding 0.2 or 0.22 micron in-line filter.

Monitor the patient closely for infusion reactions during and for at least one hour after the completion of the infusion.

Preparation

Visually inspect UPLIZNA solution for particulate matter and discoloration [see Dosage Forms and Strengths (3)]. If the solution is cloudy, discolored, or it contains discrete particulate matter, do not use and contact the manufacturer (1-800-772-6436). Do not shake the vial.

Obtain an intravenous bag containing 250 mL of 0.9% Sodium Chloride Injection, USP. Do not use other diluents to dilute UPLIZNA.

Withdraw 10 mL of UPLIZNA from each of the 3 vials contained in the carton and transfer a total of 30 mL into the 250 mL intravenous bag. Mix diluted solution by gentle inversion. Do not shake the solution.

Discard the unused portion remaining in the vials.

Storage of Infusion Solution

UPLIZNA does not contain a preservative.

Administer the prepared infusion solution immediately. If not administered immediately, store the infusion solution for a maximum of 24 hours in the refrigerator between 2°C to 8°C (36°F to 46°F) or 4 hours at room temperature between 20°C to 25°C (68°F to 77°F) prior to the start of the infusion.

Pregnancy Exposure Registry

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to UPLIZNA during pregnancy or shortly before conception. Healthcare providers are encouraged to advise their patients to register by contacting the UPLIZNA Pregnancy Registry by calling the coordinating center at 1 (303) 724-4644 or www.upliznapregnancyregistry.com.

Risk Summary

UPLIZNA is a humanized IgG1 monoclonal antibody and immunoglobulins are known to cross the placental barrier. There are no adequate data on the developmental risk associated with the use of UPLIZNA in pregnant women. However, transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other B-cell depleting antibodies during pregnancy. B-cell levels in infants following maternal exposure to UPLIZNA have not been studied in clinical trials. The potential duration of B-cell depletion in such infants, and the impact of B-cell depletion on vaccine safety and effectiveness, is unknown [see Warnings and Precautions (5.2)].

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Data

Risk Summary

There are no data on the presence of inebilizumab-cdon in human milk, the effects on a breastfed infant, or the effects on milk production. Human IgG is excreted in human milk, and the potential for absorption of UPLIZNA to lead to B-cell depletion in the breastfed infant is unknown. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for UPLIZNA and any potential adverse effects on the breastfed infant from UPLIZNA or from the underlying maternal condition.

Contraception

Women of childbearing potential should use contraception while receiving UPLIZNA and for 6 months after the last infusion of UPLIZNA [see Clinical Pharmacology (12.3)].

NMOSD

Clinical studies of UPLIZNA did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

IgG4-RD

Twenty-nine percent (32 out of 112) of patients 65 years of age or older, were treated with UPLIZNA. There were no overall age-related differences in safety or efficacy observed compared to younger patients.

Reducing the Risk of Infusion Reactions and Managing Infusion Reactions

Administer pre-medication with a corticosteroid, an antihistamine, and an antipyretic [see Dosage and Administration (2.2)].

Management recommendations for infusion reactions depend on the type and severity of the reaction. For life-threatening infusion reactions, immediately and permanently stop UPLIZNA and administer appropriate supportive treatment. For less severe infusion reactions, management may involve temporarily stopping the infusion, reducing the infusion rate, and/or administering symptomatic treatment.

Possible Increased Risk of Immunosuppressant Effects with Other Immunosuppressants

UPLIZNA has not been studied in combination with other immunosuppressants. If combining UPLIZNA with another immunosuppressive therapy, consider the potential for increased immunosuppressive effects.

Hepatitis B Virus (HBV) Reactivation

Risk of HBV reactivation has been observed with other B-cell depleting antibodies. There have been no cases of HBV reactivation in patients treated with UPLIZNA, but patients with chronic HBV infection were excluded from clinical trials. Perform HBV screening in all patients before initiation of treatment with UPLIZNA. Do not administer UPLIZNA to patients with active hepatitis. For patients who are chronic carriers of HBV [HBsAg+], consult liver disease experts before starting and during treatment.

Progressive Multifocal Leukoencephalopathy (PML)

PML is an opportunistic viral infection of the brain caused by the JC virus that typically only occurs in patients who are immunocompromised, and that usually leads to death or severe disability. Although no confirmed cases of 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. In UPLIZNA clinical trials one subject died following the development of new brain lesions for which a definitive diagnosis could not be established, though the differential diagnosis included an atypical NMOSD relapse, PML, or acute disseminated encephalomyelitis. At the first sign or symptom suggestive of PML, withhold UPLIZNA and perform an appropriate diagnostic evaluation. MRI findings may be apparent before clinical signs or symptoms. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes.

Tuberculosis

Patients should be evaluated for tuberculosis risk factors and tested for latent infection prior to initiating UPLIZNA. Consider anti-tuberculosis therapy prior to initiation of UPLIZNA in patients with a history of latent active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection. Consult infectious disease experts regarding whether initiating anti-tuberculosis therapy is appropriate before starting treatment.

Vaccinations

Administer all immunizations according to immunization guidelines at least 4 weeks prior to initiation of UPLIZNA. The safety of immunization with live or live-attenuated vaccines following UPLIZNA therapy has not been studied, and vaccination with live-attenuated or live vaccines is not recommended during treatment and until B-cell repletion.
