OCREVUS

5 WARNINGS AND PRECAUTIONS Infusion Reactions: Management recommendations for infusion reactions depend on the type and severity of the reaction. Permanently discontinue OCREVUS if a life-threatening or disabling infusion reaction occurs ( 2.3 , 5.1 ) Infections: Serious, including life-threatening and fatal infections, have occurred. Delay OCREVUS administration in patients with an active infection until the infection is resolved. Vaccination with live-attenuated or live vaccines is not recommended during treatment with OCREVUS and after discontinuation, until B-cell repletion ( 5.2 ) Progressive Multifocal Leukoencephalopathy (PML): Withhold OCREVUS at the first sign or symptom suggestive of PML ( 5.3 ) Reduction in Immunoglobulins: Monitor the level of immunoglobulins at the beginning of treatment. Monitor during and after discontinuation of treatment with OCREVUS, until B-cell repletion, and especially when recurrent serious infections are suspected. Consider discontinuing OCREVUS in patients with serious opportunistic or recurrent serious infections, and if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins ( 2.1 , 5.4 ) Malignancies: An increased risk of malignancy, including breast cancer, may exist with OCREVUS ( 5.5 ) Immune-Mediated Colitis: Immune-mediated colitis has been reported in the postmarketing setting. Monitor patients for new or persistent diarrhea or other gastrointestinal symptoms, and evaluate promptly if colitis is suspected ( 5.6 ) Liver Injury: Clinically significant liver injury has occurred. Obtain serum aminotransferases, alkaline phosphatase, and bilirubin levels before initiating OCREVUS, and during treatment as clinically indicated. Discontinue OCREVUS in patients with evidence of liver injury in the absence of an alternative etiology ( 5.7 ). 5.1 Infusion Reactions OCREVUS can cause infusion reactions, which can include pruritus, rash, urticaria, erythema, bronchospasm, throat irritation, oropharyngeal pain, dyspnea, pharyngeal or laryngeal edema, flushing, hypotension, pyrexia, fatigue, headache, dizziness, nausea, tachycardia, and anaphylaxis. These reactions are more commonly reported with the first infusion. In multiple sclerosis (MS) clinical trials, all adult and pediatric patients who were treated with OCREVUS received premedication with methylprednisolone (or an equivalent steroid), and may have also received an antihistamine (all pediatric patients) and/or an analgesic/antipyretic to reduce the risk of infusion reactions prior to each infusion. In adults, the incidence of infusion reactions in patients treated with OCREVUS was 34 to 40%. There were no fatal infusion reactions, but 0.3% of patients with MS who were treated with OCREVUS experienced infusion reactions that were serious, some requiring hospitalization. In pediatric patients, the incidence of infusion reactions in patients treated with OCREVUS was 48%, compared with an incidence of 24% in patients who received placebo infusion (fingolimod-treated patients). There were no fatal infusion reactions, but one pediatric patient (1.1%) treated with OCREVUS experienced an infusion reaction that was serious because it required hospitalization [see Adverse Reactions (6.1) ] . Observe patients treated with OCREVUS for infusion reactions during the infusion and for at least one hour after completion of the infusion. Inform patients that infusion reactions can occur up to 24 hours after the infusion. Reducing the Risk of Infusion Reactions and Managing Infusion Reactions Administer pre-medication (e.g., methylprednisolone or an equivalent corticosteroid, and an antihistamine) to reduce the frequency and severity of infusion reactions. The addition of an antipyretic (e.g., acetaminophen) may also be considered [see Dosage and Administration (2.2) ]. Management recommendations for infusion reactions depend on the type and severity of the reaction [see Dosage and Administration (2.5) ]. For life-threatening infusion reactions, immediately and permanently stop OCREVUS 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. 5.2 Infections Serious, including life-threatening or fatal, bacterial, viral, parasitic and fungal infections have been reported in patients receiving OCREVUS. An increased risk of infections (including serious and fatal bacterial, fungal, and new or reactivated viral infections) has been observed in patients during and following completion of treatment with anti-CD20 B-cell depleting therapies. A higher proportion of adult patients treated with OCREVUS experienced infections compared to patients taking REBIF or placebo. In RMS trials in adults, 58% of patients treated with OCREVUS experienced one or more infections compared to 52% of patients treated with REBIF. In the PPMS trial, 70% of patients treated with OCREVUS experienced one or more infections compared to 68% of patients on placebo. OCREVUS increased the risk for upper respiratory tract infections, lower respiratory tract infections, skin infections, and herpes-related infections [see Adverse Reactions (6.1) ]. In the pediatric study, infections occurred in 73% of patients treated with OCREVUS (1.5 infections per patient-year) and 59% of patients treated with fingolimod (1.2 infections per patient-year) [see Adverse Reactions (6.1) ] . Upper respiratory tract infections, nasopharyngitis, and influenza, all of which were mild to moderate, were more frequently reported in patients treated with OCREVUS compared to patients treated with fingolimod. Delay OCREVUS administration in patients with an active infection until the infection is resolved. Respiratory Tract Infections A higher proportion of adult patients treated with OCREVUS experienced respiratory tract infections compared to patients taking REBIF or placebo. In RMS trials in adults, 40% of patients treated with OCREVUS experienced upper respiratory tract infections compared to 33% of patients treated with REBIF, and 8% of patients treated with OCREVUS experienced lower respiratory tract infections compared to 5% of patients treated with REBIF. In the PPMS trial, 49% of patients treated with OCREVUS experienced upper respiratory tract infections compared to 43% of patients on placebo and 10% of patients treated with OCREVUS experienced lower respiratory tract infections compared to 9% of patients on placebo. The infections were predominantly mild to moderate and consisted mostly of upper respiratory tract infections and bronchitis. Herpes In active-controlled (RMS) clinical trials in adults, herpes infections were reported more frequently in patients treated with OCREVUS than in patients treated with REBIF, including herpes zoster (2.1% vs. 1.0%), herpes simplex (0.7% vs. 0.1%), oral herpes (3.0% vs. 2.2%), genital herpes (0.1% vs. 0%), and herpes virus infection (0.1% vs. 0%). Infections were predominantly mild to moderate in severity. In the placebo-controlled (PPMS) clinical trial, oral herpes was reported more frequently in the patients treated with OCREVUS than in the patients on placebo (2.7% vs 0.8%). 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, have been reported in the postmarketing setting in multiple sclerosis patients receiving OCREVUS. Serious herpes virus infections may occur at any time during treatment with OCREVUS. Some cases were life-threatening. If serious herpes infections occur, OCREVUS should be discontinued or withheld until the infection has resolved, and appropriate treatment should be administered [see Patient Counseling Information (17) ]. Hepatitis B Virus (HBV) Reactivation Hepatitis B reactivation has been reported in MS patients treated with OCREVUS in the postmarketing setting. Fulminant hepatitis, hepatic failure, and death caused by HBV reactivation have occurred in patients treated with anti-CD20 antibodies. Perform HBV screening in all patients before initiation of treatment with OCREVUS. Do not administer OCREVUS 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. Possible Increased Risk of Immunosuppressant Effects with Other Immunosuppressants When initiating OCREVUS after an immunosuppressive therapy or initiating an immunosuppressive therapy after OCREVUS, consider the potential for increased immunosuppressive effects [see Drug Interactions (7.1) and Clinical Pharmacology (12.1 , 12.2) ]. OCREVUS has not been studied in combination with other MS therapies. Vaccinations Administer all age-appropriate immunizations according to immunization guidelines at least 4 weeks prior to initiation of OCREVUS for live or live-attenuated vaccines and, whenever possible, at least 2 weeks prior to initiation of OCREVUS for non-live vaccines. OCREVUS may interfere with the effectiveness of non-live vaccines [see Drug Interactions (7.2) ]. The safety of immunization with live or live-attenuated vaccines following OCREVUS therapy has not been studied, and vaccination with live-attenuated or live vaccines is not recommended during treatment and until B-cell repletion [see Clinical Pharmacology (12.2) ] . Vaccination of Infants Born to Mothers Treated with OCREVUS During Pregnancy In infants of mothers exposed to OCREVUS during pregnancy, do not administer live or live-attenuated vaccines before confirming the recovery of B-cell counts as measured by CD19 + B-cells. Depletion of B-cells in these infants may increase the risks from live or live-attenuated vaccines. If indicated, non-live vaccines may be administered prior to recovery from B-cell depletion, but assessment of vaccine immune responses, including consultation with a qualified specialist, should be considered to assess whether a protective immune response was mounted [see Use in Specific Populations (8.1) ]. 5.3 Progressive Multifocal Leukoencephalopathy Cases of progressive multifocal leukoencephalopathy (PML) have been reported in patients with MS treated with OCREVUS in the postmarketing setting. 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. PML has occurred in OCREVUS-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 OCREVUS, and did not have any known ongoing systemic medical conditions resulting in compromised immune system function. JCV infection resulting in PML has also been observed in patients treated with other anti-CD20 antibodies and other MS therapies. At the first sign or symptom suggestive of PML, withhold OCREVUS 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. MRI findings may be apparent before clinical signs or symptoms. Cases of PML, diagnosed based on MRI findings and the detection of JCV DNA in the cerebrospinal fluid in the absence of clinical signs or symptoms specific to PML, have been reported in patients treated with other MS medications associated with PML. Many of these patients subsequently became symptomatic with PML. Therefore, 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. It is not known whether these differences are due to early detection and discontinuation of MS treatment or due to differences in disease in these patients. If PML is confirmed, treatment with OCREVUS should be discontinued. 5.4 Reduction in Immunoglobulins As expected with any B-cell depleting therapy, decreased immunoglobulin levels are observed with OCREVUS treatment. The pooled data of OCREVUS clinical studies (RMS and PPMS) in adults and their open-label extensions (up to approximately 7 years of exposure) have shown an association between decreased levels of immunoglobulin G (IgG<LLN) and increased rates of serious infections. Monitor the levels of quantitative serum immunoglobulins during OCREVUS treatment and after discontinuation of treatment, until B-cell repletion, and especially in the setting of recurrent serious infections. Consider discontinuing OCREVUS therapy in patients with serious opportunistic or recurrent serious infections, and if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins [see Adverse Reactions (6.1) ] . 5.5 Malignancies An increased risk of malignancy with OCREVUS may exist. In controlled trials, malignancies, including breast cancer, occurred more frequently in patients treated with OCREVUS. Breast cancer in adults occurred in 6 of 781 females treated with OCREVUS and none of 668 females treated with REBIF or placebo. Patients should follow standard breast cancer screening guidelines. 5.6 Immune-Mediated Colitis Immune-mediated colitis, which can present as a severe and acute-onset form of colitis, has been reported in patients receiving OCREVUS in the 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 OCREVUS 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. 5.7 Liver Injury 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 OCREVUS. 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 OCREVUS found to have an alanine aminotransferase (ALT) or aspartate aminotransferase (AST) greater than 3× the upper limit of normal (ULN) with serum total bilirubin greater than 2× ULN are potentially at risk for severe drug-induced liver injury. Obtain liver function tests prior to initiating treatment with OCREVUS [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 OCREVUS.

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: Infusion Reactions [see Warnings and Precautions (5.1) ] Infections [see Warnings and Precautions (5.2) ] Progressive Multifocal Leukoencephalopathy [see Warnings and Precautions (5.3) ] Reduction in Immunoglobulins [see Warnings and Precautions (5.4) ] Malignancies [see Warnings and Precautions (5.5) ] Immune-Mediated Colitis [see Warnings and Precautions (5.6) ] Liver Injury [see Warnings and Precautions (5.7) ] The most common adverse reactions were: RMS (incidence ≥10% and > REBIF ® ): upper respiratory tract infections and infusion reactions ( 6.1 ) PPMS (incidence ≥10% and > placebo): upper respiratory tract infections, infusion reactions, skin infections, and lower respiratory tract infections ( 6.1 ) RRMS in pediatric patients 10 years of age and older: Adverse reactions were consistent with those observed in adults with RMS ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Genentech at 1-888-835-2555 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reactions rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Adults The safety of OCREVUS has been evaluated in 1311 adult patients across MS clinical studies, which included 825 patients in active-controlled clinical trials in patients with relapsing forms of MS (RMS) and 486 patients in a placebo-controlled study in patients with primary progressive MS (PPMS). Adverse Reactions in Adult Patients with Relapsing Forms of MS In active-controlled clinical trials (Study 1 and Study 2), 825 patients with RMS received OCREVUS 600 mg intravenously every 24 weeks (initial treatment was given as two separate 300 mg infusions at Weeks 0 and 2) [see Clinical Studies (14.1) ]. The overall exposure in the 96-week controlled treatment periods was 1448 patient-years. The most common adverse reactions in RMS trials (incidence ≥ 10%) were upper respiratory tract infections and infusion reactions. Table 4 summarizes the adverse reactions that occurred in RMS trials (Study 1 and Study 2). Table 4 Adverse Reactions in Adult Patients with RMS with an Incidence of at least 5% for OCREVUS and Higher than REBIF Adverse Reactions Studies 1 and 2 OCREVUS 600 mg IV Every 24 Weeks The first dose was given as two separate 300 mg infusions at Weeks 0 and 2.

The overall exposure in the controlled treatment period was 1416 patient-years, with median treatment duration of 3 years. The most common adverse reactions in the PPMS trial (incidence ≥ 10%) were upper respiratory tract infections, infusion reactions, skin infections, and lower respiratory tract infections. Table 5 summarizes the adverse reactions that occurred in the PPMS trial (Study 3). Table 5 Adverse Reactions in Adult Patients with PPMS with an Incidence of at least 5% for OCREVUS and Higher than Placebo Adverse Reactions Study 3 OCREVUS 600 mg IV Every 24 Weeks One dose of OCREVUS (600 mg administered as two 300 mg infusions two weeks apart) Placebo (n=486) % (n=239) % Upper respiratory tract infections 49 43 Infusion reactions 40 26 Skin infections 14 11 Lower respiratory tract infections 10 9 Cough 7 3 Diarrhea 6 5 Edema peripheral 6 5 Herpes virus associated infections 5 4 Adverse Reactions in Adult Patients who Received 2-hour Infusions Study 4 was designed to characterize the safety profile of OCREVUS infusions administered over 2 hours in patients with Relapsing-Remitting Multiple Sclerosis who did not experience a serious infusion reaction with any previous OCREVUS infusion. In this study, the incidence, intensity, and types of symptoms of infusion reactions were consistent with those of infusions administered over 3.5 hours [see Clinical Studies (14.3) ] . Laboratory Abnormalities in Adults Decreased Immunoglobulins OCREVUS decreased total immunoglobulins with the greatest decline seen in IgM levels; however, a decrease in IgG levels was associated with an increased rate of serious infections . In the active-controlled (RMS) trials (Study 1 and Study 2), the proportion of patients at baseline reporting IgG, IgA, and IgM below the lower limit of normal (LLN) in OCREVUS-treated patients was 0.5%, 1.5%, and 0.1%, respectively. Following treatment, the proportion of OCREVUS-treated patients reporting IgG, IgA, and IgM below the LLN at 96 weeks was 1.5%, 2.4%, and 16.5%, respectively. In the placebo-controlled (PPMS) trial (Study 3), the proportion of patients at baseline reporting IgG, IgA, and IgM below the LLN in OCREVUS-treated patients was 0.0%, 0.2%, and 0.2%, respectively. Following treatment, the proportion of OCREVUS-treated patients reporting IgG, IgA, and IgM below the LLN at 120 weeks was 1.1%, 0.5%, and 15.5%, respectively. The pooled data of OCREVUS clinical studies (RMS and PPMS) and their open-label extensions (up to approximately 7 years of exposure) have shown an association between decreased levels of IgG and increased rates of serious infections. The type, severity, latency, duration, and outcome of serious infections observed during episodes of immunoglobulins below LLN were consistent with the overall serious infections observed in patients treated with OCREVUS. Decreased Neutrophil Levels In the PPMS clinical trial (Study 3), decreased neutrophil counts occurred in 13% of OCREVUS-treated patients compared to 10% in placebo patients. The majority of the decreased neutrophil counts were only observed once for a given patient treated with OCREVUS and were between LLN - 1.5 × 10 9 /L and 1.0 × 10 9 /L. Overall, 1% of the patients in the OCREVUS group had neutrophil counts less than 1.0 × 10 9 /L and these were not associated with an infection. Pediatric Patients Adverse Reactions in Patients 10 to Less Than 18 Years of Age with Relapsing-Remitting MS The safety of OCREVUS in pediatric patients with relapsing-remitting MS was evaluated in one randomized, double-blind clinical study in 185 patients, 93 of whom received OCREVUS and 92 of whom received fingolimod [see Clinical Studies (14.4) ] . In the controlled pediatric trial (Study 5), the safety profile in pediatric patients was consistent with that observed in adult patients. Infusion Reactions Infusion reactions were the most common adverse reactions in patients treated with OCREVUS with an incidence of 48%, compared to an incidence of 24% in fingolimod-treated patients (placebo infusion). The incidence of infusion reactions was highest at 31% with infusion 1 of the initial dose (on day 1), and decreased to 9% with infusion 2 of the initial dose (on day 15). At the first subsequent dose (at 6 months), 16% of patients had an infusion reaction. The incidence and severity of infusion reactions decreased with additional subsequent infusions. The majority of infusion reactions were mild to moderate. One infusion reaction with infusion 1 of the initial dose was reported as serious because it required hospitalization. Infections Infections were observed in 73% of patients treated with OCREVUS (1.5 infections per patient-year) and 59% of patients treated with fingolimod (1.2 infections per patient-year). Serious infections occurred in 3% of patients treated with OCREVUS (0.03 serious infections per patient-year) compared to 3% of fingolimod-treated patients (0.03 serious infections per patient-year). Laboratory Abnormalities Decreased Immunoglobulins OCREVUS decreased total immunoglobulins over the controlled period of Study 5, with the greatest decline seen in IgM levels. Similar to the pattern observed in the adult population, reduction in IgM occurred earlier and in a higher proportion of patients compared to IgG and IgA. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of OCREVUS. 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. Gastrointestinal Disorders: Immune-mediated colitis [see Warnings and Precautions (5.6) ] Hepatobiliary Disorders: Liver injury [see Warnings and Precautions (5.7) ] Infections and Infestations: Serious herpes infections [see Warnings and Precautions (5.2) ] , progressive multifocal leukoencephalopathy [see Warnings and Precautions (5.3) ] , and babesiosis Skin: Pyoderma gangrenosum
