5 Warnings and Precautions

5.2 Infections

Additions and/or revisions underlined:

Progressive Multifocal Leukoencephalopathy (PML)

PML is an opportunistic viral infection of the brain caused by the JC virus (JCV) that typically only occurs in patients who are immunocompromised, and that usually leads to death or severe disability. JCV infection resulting in PML has been observed in patients treated with anti-CD20 antibodies, including BRIUMVI, and other MS therapies. At the first sign or symptom suggestive of PML, withhold BRIUMVI and perform an appropriate diagnostic evaluation. 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.

6 Adverse Reactions

6.2 Postmarketing Experience

Additions and/or revisions underlined:

The following adverse reactions have been identified during postapproval use of BRIUMVI. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Hepatobiliary Disorders: Liver injury [see Warnings and Precautions (5.5)]

Infections and Infestations: Progressive multifocal leukoencephalopathy [see Warnings and Precautions (5.2)]

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

Additions and/or revisions underlined:

Advise patients that PML has happened with BRIUMVI. Inform the patient that PML is characterized by a progression of deficits and usually leads to death or severe disability over weeks or months. Instruct the patient of the importance of contacting their doctor if they develop any symptoms suggestive of PML. Inform the patient that 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 [see Warnings and Precautions (5.2)].

MEDICATION GUIDE

Additions and/or revisions underlined:

  • Infections. Infections are a common side effect, and upper respiratory tract infections are one of the most common side effects of BRIUMVI. BRIUMVI increases your risk of getting infections caused by bacteria or viruses that may be life-threatening or cause death. Tell your healthcare provider if you have an infection or have any of the following signs of infection including fever, chills, a cough that does not go away, or painful urination. Your healthcare provider should delay your treatment with BRIUMVI until your infection is gone.

    • Progressive Multifocal Leukoencephalopathy (PML): PML has happened with BRIUMVI. PML is a rare, serious brain infection caused by a virus that may get worse over days or weeks. PML can result in death or severe disability. Tell your healthcare provider right away if you have any new or worsening neurologic signs or symptoms. These symptoms may include weakness on one side of your body, loss of coordination in arms and legs, vision problems, changes in thinking and memory which may lead to confusion, and personality changes.

5 Warnings and Precautions

5.5 Liver Injury

Newly added subsection:

Clinically significant liver injury, without findings of viral hepatitis, has been reported in the postmarketing setting in patients treated with anti-CD20 B-cell depleting therapies approved for the treatment of MS, including BRIUMVI. Signs of liver injury, including markedly elevated serum hepatic enzymes with elevated total bilirubin, have occurred from weeks to months after administration.

Patients treated with BRIUMVI found to have an alanine aminotransaminase (ALT) or aspartate aminotransferase (AST) greater than 3x the upper limit of normal (ULN) with serum total bilirubin greater than 2x ULN are potentially at risk for severe drug-induced liver injury.

Obtain liver function tests prior to initiating treatment with BRIUMVI [see Dosage and Administration (2.1)], and monitor for signs and symptoms of any hepatic injury during treatment. Measure serum aminotransferases, alkaline phosphatase, and bilirubin levels promptly in patients who report symptoms that may indicate liver injury, including new or worsening fatigue, anorexia, nausea, vomiting, right upper abdominal discomfort, dark urine, or jaundice. If liver injury is present and an alternative etiology is not identified, discontinue BRIUMVI.

6 Adverse Reactions

Addition of the following to the bulleted line listing:

  • Liver Injury [see Warnings and Precautions (5.5)]

6.2 Postmarketing Experience

Newly added subsection:

The following adverse reactions have been identified during postapproval use of BRIUMVI. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Hepatobiliary Disorders: Liver injury [see Warnings and Precautions (5.5)]

8 Use in Specific Populations

8.1 Pregnancy

Additions and/or revisions underlined:

Risk Summary

In pregnant transgenic huCD20 mice, a pharmacologically relevant animal model, weekly intravenous administration of ublituximab-xiiy during organogenesis resulted in no adverse pregnancy or embryofetal outcomes (see Data).

Data

Animal Data

The findings in cynomolgus monkey were considered secondary to an immunogenic reaction and are not considered relevant to humans.

In a subsequent study conducted in pregnant CD20 (huCD20) transgenic mice, a pharmacologically relevant animal model, intravenous administration of ublituximab-xiiy (0, 5, 20, or 50 mg/kg) during organogenesis (gestation day 6 and 12) resulted in no adverse effects on embryofetal development. There was a marked reduction in B-cells in fetal blood at all but the lowest dose tested.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Liver Injury

Inform patients that liver injury has been reported with anti-CD20 B-cell depleting therapies, including BRIUMVI. Instruct patients treated with BRIUMVI to promptly report any symptoms that may indicate liver injury, including fatigue, anorexia, nausea, vomiting, right upper abdominal discomfort, dark urine, or jaundice. A blood test should be obtained before patients start therapy, and during treatment as clinically indicated [see Warnings and Precautions (5.5)].

MEDICATION GUIDE

Additions and/or revisions underlined:

Before receiving BRIUMVI, tell your healthcare provider about all of your medical conditions, including if you:

  • have a history of liver problems.

     

  • are pregnant, think that you might be pregnant, or plan to become pregnant. It is not known if BRIUMVI will harm your unborn baby. You should use birth control (contraception) during treatment with BRIUMVI and for at least 6 months after your last infusion of BRIUMVI. Talk with your healthcare provider about what birth control method is right for you during this time.

    What are the possible side effects of BRIUMVI?

    BRIUMVI may cause serious side effects, including:

  • See “What is the most important information I should know about BRIUMVI?”

  • Liver damage. BRIUMVI may cause liver damage. Your healthcare provider will do blood tests to check your liver

    before you start BRIUMVI and while you take BRIUMVI if needed. Tell your healthcare provider right away if you have any symptoms of liver damage, such as:

  • yellowing of the skin and eyes (jaundice)

  • nausea

  • vomiting

  • unusual darkening of the urine

  • feeling tired or weak
