                triamcinolone acetonide injectable suspension and ocrelizumab both increase immunosuppressive effects; risk of infection. Use Caution/Monitor. Coadministration of ocrelizumab with high doses of corticosteroids is expected to increase the risk of immunosuppression.

              • ublituximab

                ublituximab and ocrelizumab both increase immunosuppressive effects; risk of infection. Modify Therapy/Monitor Closely. Owing to potential additive immunosuppressive effects, consider duration of effect and mechanism of action of these therapies if coadministered

              • zoster vaccine recombinant

                ocrelizumab decreases effects of zoster vaccine recombinant by pharmacodynamic antagonism. Use Caution/Monitor. Immunosuppressive therapies may reduce the effectiveness of zoster vaccine recombinant.

                Active HBV infection

                History of life-threatening infusion reaction to ocrelizumab

                Cautions

                Infusion reactions (eg, pruritus, rash, urticaria, erythema, bronchospasm, throat irritation, oropharyngeal pain, dyspnea, pharyngeal or laryngeal edema, flushing, hypotension, pyrexia, fatigue, headache, dizziness, nausea, tachycardia) may occur; monitor during treatment and at least 1 hr after treatment; inform patients that infusion reactions can occur up to 24 hours after infusion

                B-cell depleting therapy decreases immunoglobulin levels, which is associated with increased rates of serious infections; monitor levels of quantitative serum immunoglobulins during treatment and after discontinuing until B-cell repletion; consider discontinuing in patients with serious opportunistic or recurrent serious infection, and if prolonged hypogammaglobulinemia requires treatment with IVIG

                Increased risk of malignancy, including breast cancer exists; patients should follow standard breast cancer screening guidelines

                Infections

                • In clinical trials, a higher proportion of ocrelizumab-treated patients experienced infections (eg, respiratory tract) compared with interferon-beta1a or placebo
                • HBV reactivation: Fulminant hepatitis, hepatic failure, and death caused by HBV reactivation have occurred in patients treated with other anti-CD20 antibodies
                • Perform HBV screening in all patients before initiation of treatment; do not administer to patients with active HBV confirmed by positive results for HBsAg and anti-HB tests; for patients who are negative for surface antigen [HBsAg] and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult liver disease experts before starting and during treatment
                • Herpes simplex virus
                  • Serious cases of infections caused by herpes simplex virus and varicella-zoster virus, including central nervous system infections (encephalitis and meningitis), intraocular infections, and disseminated skin and soft tissue infections, reported in the postmarketing setting
                  • Serious herpes virus infections may occur at any time during treatment; some cases life-threatening
                  • If serious herpes infections occur, discontinue therapy or withhold until infection has resolved; appropriate treatment should be administered
                • Progressive multifocal leukoencephalopathy (PML)
                  • PML is an opportunistic viral infection of the brain caused by the John Cunningham (JC) virus
                  • PML observed in patients treated with other anti-CD20 antibodies and other multiple sclerosis therapies and has also been associated with some risk factors (eg, immunocompromised patients, polytherapy with immunosuppressants)
                  • PML has occurred in ocrelizumab-treated patients who had not been treated previously with natalizumab (which has a known association with PML), were not taking any immunosuppressive or immunomodulatory medications associated with the risk of PML prior to or concomitantly with this drug, and did not have any known ongoing systemic medical conditions resulting in compromised immune system function
                  • 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
                  • MRI findings may be apparent before clinical signs or symptoms; cases of PML, diagnosed based on MRI findings and detection of JCV DNA in the cerebrospinal fluid in absence of clinical signs or symptoms specific to PML, reported in patients treated with other MS medications associated with PML
                  • Monitoring with MRI for signs that may be consistent with PML may be useful, and any suspicious findings should lead to further investigation to allow for an early diagnosis of PML, if present; following discontinuation of another MS medication associated with PML, lower PML-related mortality and morbidity have been reported in patients who were initially asymptomatic at diagnosis compared to patients who had characteristic clinical signs and symptoms at diagnosis
                  • Not known whether these differences are due to early detection and discontinuation of MS treatment or due to differences in disease in these patients
                  • At the first sign or symptom suggestive of PML, withhold drug and perform an appropriate diagnostic evaluation; if PML confirmed, treatment should be discontinued

                Immune-mediated colitis

                • Immune-mediated colitis, which can present as a severe and acute-onset form of colitis, reported in patients receiving this medication in postmarketing setting; some cases of colitis were serious, requiring hospitalization, with a few patients requiring surgical intervention; systemic corticosteroids were required in many of these patients
                • The time from treatment initiation to onset of symptoms in these cases ranged from a few weeks to years; monitor patients for immune-mediated colitis during treatment, and evaluate promptly if signs and symptoms that may indicate immune-mediated colitis, such as new or persistent diarrhea or other gastrointestinal signs and symptoms, occur

                Drug interaction overview

                • Coadministration with immunosuppressants may increase risk for immunosuppressive effects
                • Vaccinations
                  • May interfere with efficacy of nonlive vaccines (live or live-attenuated vaccines not studied)
                  • Administer all immunizations according to immunization guidelines at least 4 weeks prior to initiation for live or live-attenuated vaccines and, whenever possible, at least 2 weeks prior to initiation for nonlive vaccines
                • Vaccination of infants of mothers exposed to ocrelizumab during pregnancy
                  • Do not administer live or live-attenuated vaccines before confirming recovery of B-cell counts (measured by CD19+ B-cells)
                  • Depletion of B-cells in these infants may increase risks from live or live-attenuated vaccines
                  • Nonlive vaccines may be administered as indicated, prior to recovery from B-cell depletion; consider assessing vaccine immune responses, including consultation with a qualified specialist, to assess whether a protective immune response was mounted

                Pregnancy

                No data available to assess risk in pregnant women

                Drug is a humanized monoclonal antibody of an immunoglobulin G1 subtype and immunoglobulins are known to cross the placental barrier

                However, transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other anti-CD20 antibodies during pregnancy

                B-cell levels in infants following maternal exposure to drug have not been studied in clinical trials; the potential duration of B-cell depletion in such infants, and impact of B-cell depletion on vaccine safety and effectiveness, is unknown

                See Cautions for information regarding vaccinating infants born to mothers taking ocrelizumab

                A pregnancy exposure registry monitors pregnancy and fetal/neonatal/infant outcomes in women exposed to OCREVUS during pregnancy; physicians are encouraged to register patients and pregnant women are encouraged to register themselves by calling 1-833-872-4370 or visiting www.ocrevuspregnancyregistry.com

                Contraception

                • Women of childbearing potential should use contraception while receiving ocrelizumab and for 6 months after the last infusion

                Lactation

                Unknown if distributed in human breast milk

                Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition

                Pregnancy Categories

                A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                NA: Information not available.
