- If the dose is not to be administered immediately, use aseptic technique to withdraw the entire OCREVUS ZUNOVO contents from the vial into the syringe to account for the dose volume (23 mL) plus the priming volume for the subcutaneous infusion set. Replace the transfer needle with a syringe closing cap. DO NOT attach a subcutaneous infusion set.
- If not used immediately, the closed syringe can be refrigerated (2°C to 8°C [36°F to 46°F]) for up to 72 hours followed by 8 hours at ambient temperatures at or below 25°C (77°F) in diffuse daylight.
- If the prepared syringe was stored at 2°C to 8°C (36°F to 46°F), allow the syringe to acclimate to room temperature prior to administration.
Injection: 920 mg ocrelizumab and 23,000 units hyaluronidase per 23 mL (40 mg and 1,000 units per mL) clear to slightly opalescent, and colorless to pale brown solution in a single-dose vial.
Reducing the Risk of Injection Reactions and Managing Injection Reactions
Administer oral premedication (e.g., dexamethasone or an equivalent corticosteroid, and an antihistamine) at least 30 minutes prior to each OCREVUS ZUNOVO injection to reduce the risk of injection reactions. The addition of an antipyretic (e.g., acetaminophen) may also be considered [see Dosage and Administration (2.3)].
Management recommendations for injection reactions depend on the type and severity of the reaction. For life-threatening injection reactions, immediately and permanently stop OCREVUS ZUNOVO and administer appropriate supportive treatment. For less severe injection reactions, the injection should be interrupted immediately, and the patient should receive symptomatic treatment. The injection should be completed at the healthcare provider's discretion and only after all symptoms have resolved.
Respiratory Tract Infections
A higher proportion of intravenous ocrelizumab-treated patients experienced respiratory tract infections compared to patients taking REBIF or placebo. In RMS trials, 40% of patients treated with intravenous ocrelizumab experienced upper respiratory tract infections compared to 33% of REBIF-treated patients, and 8% of patients treated with intravenous ocrelizumab experienced lower respiratory tract infections compared to 5% of REBIF-treated patients. In the PPMS trial, 49% of patients treated with intravenous ocrelizumab experienced upper respiratory tract infections compared to 43% of patients on placebo, and 10% of patients treated with intravenous ocrelizumab 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, herpes infections were reported more frequently in patients treated with intravenous ocrelizumab than in REBIF-treated patients, 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 intravenous ocrelizumab 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 ocrelizumab. Some cases were life-threatening. Serious herpes virus infections may occur at any time during treatment with OCREVUS ZUNOVO.
If serious herpes infections occur, OCREVUS ZUNOVO should be discontinued or withheld until the infection has resolved, and appropriate treatment should be administered [see Patient Counseling Information (17)].
Hepatitis B Virus Reactivation
Hepatitis B virus (HBV) reactivation has been reported in MS patients treated with ocrelizumab 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 ocrelizumab. Do not administer OCREVUS ZUNOVO 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 ZUNOVO after an immunosuppressive therapy or initiating an immunosuppressive therapy after OCREVUS ZUNOVO, consider the potential for increased immunosuppressive effects [see Drug Interactions (7.1) and Clinical Pharmacology (12.1, 12.2)]. OCREVUS ZUNOVO has not been studied in combination with other MS therapies.
Vaccinations
Administer all immunizations according to immunization guidelines at least 4 weeks prior to initiation of ocrelizumab treatment for live or live-attenuated vaccines and, whenever possible, at least 2 weeks prior to initiation of ocrelizumab for non-live vaccines.
OCREVUS ZUNOVO 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 ZUNOVO 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 ZUNOVO During Pregnancy
In infants of mothers exposed to OCREVUS ZUNOVO 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.
You may administer non-live vaccines, as indicated, prior to recovery from B-cell depletion, but should consider assessing vaccine immune responses, including consultation with a qualified specialist, to assess whether a protective immune response was mounted [see Use in Specific Populations (8.1)].
Adverse Reactions With Ocrelizumab Intravenous in Patients With RMS and PPMS
The safety of intravenous ocrelizumab has been evaluated in 1311 patients across the MS clinical studies, which included 825 patients in active-controlled clinical trials in patients with RMS and 486 patients in a placebo-controlled study in patients with PPMS.
RMS
In active-controlled intravenous ocrelizumab clinical trials (Study 1 and Study 2), 825 patients with RMS received ocrelizumab 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 1 summarizes the adverse reactions that occurred in active-controlled intravenous ocrelizumab RMS trials (Study 1 and Study 2).

PPMS
In a placebo-controlled intravenous ocrelizumab clinical trial (Study 3), a total of 486 patients with PPMS received one course of ocrelizumab (600 mg of ocrelizumab administered as two 300 mg infusions two weeks apart) given intravenously every 24 weeks and 239 patients received placebo intravenously [see Clinical Studies (14.2)]. 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 2 summarizes the adverse reactions that occurred in the placebo-controlled intravenous ocrelizumab PPMS trial (Study 3).

Laboratory Abnormalities
Decreased Immunoglobulins
Ocrelizumab 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 patients treated with intravenous ocrelizumab was 0.5%, 1.5%, and 0.1%, respectively. Following treatment, the proportion of patients treated with intravenous ocrelizumab 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 patients treated with intravenous ocrelizumab was 0.0%, 0.2%, and 0.2%, respectively. Following treatment, the proportion of patients treated with intravenous ocrelizumab reporting IgG, IgA, and IgM below the LLN at 120 weeks was 1.1%, 0.5%, and 15.5%, respectively.
The pooled data of intravenous ocrelizumab 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 intravenous ocrelizumab.
Decreased Neutrophil Levels
In the PPMS clinical trial (Study 3), decreased neutrophil counts occurred in 13% of patients treated with intravenous ocrelizumab compared to 10% in placebo patients. The majority of the decreased neutrophil counts were only observed once for a given patient treated with intravenous ocrelizumab and were between the LLN and 1.0 × 109/L. Overall, 1% of the patients in the intravenous ocrelizumab group had neutrophil counts less than 1.0 × 109/L and these were not associated with an infection.
Adverse Reactions With OCREVUS ZUNOVO in Patients With RMS and PPMS
The safety of OCREVUS ZUNOVO was evaluated in Study 4, an active-controlled, open-label, randomized study in ocrelizumab-naïve patients with RMS or PPMS [see Clinical Studies (14.3)]. One hundred eighteen patients received OCREVUS ZUNOVO as their first dose and 118 patients received intravenous ocrelizumab for their first dose (two separate 300 mg infusions at Weeks 0 and 2).
The most common adverse reactions (reported in at least 10% of OCREVUS ZUNOVO-treated patients) were injection reactions.
In Study 4, injection reactions occurred in 49% (58/118) of patients after the first injection of OCREVUS ZUNOVO. Of these 118 patients, 47% and 11% experienced at least one local injection reaction and one systemic injection reaction, respectively. The most common symptoms reported by patients with local and systemic injection reactions included: injection site erythema, injection site pain, injection site swelling, injection site pruritus, headache, and nausea. Among the patients experiencing an injection reaction, the majority of patients (83%) had injection reactions occur within 24 hours after the end of the injection, as opposed to during the injection (19%). All injection reactions were of mild (73%) or moderate (27%) severity. The median duration of symptoms was 3 days for systemic injection reactions and 3.5 days for local injection reactions. All patients recovered from injection reactions, of which 26% required symptomatic treatment.
For subsequent injections, among the 118 patients who received OCREVUS ZUNOVO only throughout the study, the frequency of local injection reactions ranged from 31% to 43% and the frequency of systemic injection reactions ranged from 3% to 7% from Injection 2 to Injection 4. All injection reactions were of mild or moderate severity.
Risk Summary
OCREVUS ZUNOVO is a humanized monoclonal antibody of an immunoglobulin G1 subtype and immunoglobulins are known to cross the placental barrier. There are no adequate data on the developmental risk associated with use of OCREVUS ZUNOVO or ocrelizumab-containing products in pregnant women. 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 OCREVUS ZUNOVO or ocrelizumab-containing products 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)].
Following administration of ocrelizumab to pregnant monkeys at doses similar to or greater than those used clinically, increased perinatal mortality, depletion of B-cell populations, and renal, bone marrow, and testicular toxicity were observed in the offspring in the absence of maternal toxicity [see Data].
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. The background risk of major birth defects and miscarriage for the indicated population is unknown.
Data
Animal Data
OCREVUS ZUNOVO for subcutaneous injection contains ocrelizumab and hyaluronidase [see Description (11)].
Ocrelizumab:
- -Following intravenous administration of ocrelizumab to monkeys during organogenesis (loading doses of 15 or 75 mg/kg on gestation days 20, 21, and 22, followed by weekly doses of 20 or 100 mg/kg), depletion of B-lymphocytes in lymphoid tissue (spleen and lymph nodes) was observed in fetuses at both doses.
- -Intravenous administration of ocrelizumab (three daily loading doses of 15 or 75 mg/kg, followed by weekly doses of 20 or 100 mg/kg) to pregnant monkeys throughout the period of organogenesis and continuing through the neonatal period resulted in perinatal deaths (some associated with bacterial infections), renal toxicity (glomerulopathy and inflammation), lymphoid follicle formation in the bone marrow, and severe decreases in circulating B-lymphocytes in neonates. The cause of the neonatal deaths is uncertain; however, both affected neonates were found to have bacterial infections. Reduced testicular weight was observed in neonates at the high dose.
- -A no-effect dose for adverse developmental effects was not identified; the doses tested in monkey are 2 and 10 times the recommended human dose of 600 mg intravenous ocrelizumab, on a mg/kg basis.
Hyaluronidase:
- -In an embryo-fetal study, mice were dosed daily by subcutaneous injection during the period of organogenesis with hyaluronidase (human recombinant) at dose levels up to 2,200,000 U/kg, which is > 5,700 times higher than the human dose. The study found no evidence of teratogenicity. Reduced fetal weight and increased numbers of fetal resorptions were observed, with no effects found at a daily dose of 360,000 U/kg, which is > 940 times higher than the human dose.
- -In a pre-and postnatal development study, mice have been dosed daily by subcutaneous injection, with hyaluronidase (human recombinant) from implantation through lactation and weaning at dose levels up to 1,100,000 U/kg, which is > 2,800 times higher than the human dose. The study found no adverse effects on sexual maturation, learning and memory, or fertility of the offspring.
Risk Summary
There are no data on the presence of ocrelizumab or hyaluronidase, from administration of OCREVUS ZUNOVO, in human milk, the effects on the breastfed infant, or the effects of the drug on milk production. Ocrelizumab was excreted in the milk of ocrelizumab-treated monkeys. Human IgG is excreted in human milk, and the potential for absorption of ocrelizumab to lead to B-cell depletion in the infant is unknown. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for OCREVUS ZUNOVO and any potential adverse effects on the breastfed infant from OCREVUS ZUNOVO or from the underlying maternal condition.
Contraception
Women of childbearing potential should use effective contraception while receiving OCREVUS ZUNOVO and for 6 months after the last dose of OCREVUS ZUNOVO [see Clinical Pharmacology (12.3)].
Distribution
The population PK estimate of the central volume of distribution was 2.78 L. Peripheral volume and inter-compartment clearance were estimated at 2.68 L and 0.55 L/day, respectively.
Elimination
Constant clearance was estimated at 0.17 L/day, and initial time-dependent clearance at 0.05 L/day, which declined with a half-life of 33 weeks. The terminal elimination half-life was 20 days.
Metabolism
The metabolism of OCREVUS ZUNOVO has not been directly studied because antibodies are cleared principally by catabolism.
Specific Populations
Renal Impairment
Patients with mild renal impairment were included in clinical trials. No significant change in the pharmacokinetics of ocrelizumab was observed in those patients.
Hepatic Impairment
Patients with mild hepatic impairment were included in clinical trials. No significant change in the pharmacokinetics of ocrelizumab was observed in those patients.
Injection Reactions
Inform patients that the signs and symptoms of injection reactions can be local or systemic, and that injection reactions can occur up to 24 hours after injection. Advise patients to contact their healthcare provider immediately for signs or symptoms of injection reactions [see Warnings and Precautions (5.1)].
Infection
Advise patients to contact their healthcare provider for any signs of infection during treatment or after the last dose [see Clinical Pharmacology (12.2)]. Signs include fever, chills, constant cough, dysuria, or signs of herpes such as cold sores, shingles, or genital sores [see Warnings and Precautions (5.2)].
Advise patients that OCREVUS ZUNOVO may cause reactivation of hepatitis B infection and that monitoring will be required if they are at risk [see Warnings and Precautions (5.2)].
Advise patients that herpes infections, including serious herpes infections affecting the central nervous system, skin, and eyes, have occurred during treatment with ocrelizumab. Advise patients to promptly contact their healthcare provider if they experience any signs or symptoms of herpes infections including oral or genital symptoms, fever, skin rash, pain, itching, decreased visual acuity, eye redness, eye pain, headache, neck stiffness, or change in mental status [see Warnings and Precautions (5.2)].
Vaccination
Advise patients to complete any required live or live-attenuated vaccinations at least 4 weeks and, whenever possible, non-live vaccinations at least 2 weeks prior to initiation of ocrelizumab treatment. Administration of live-attenuated or live vaccines is not recommended during OCREVUS ZUNOVO treatment and until B-cell recovery [see Warnings and Precautions (5.2)].
Progressive Multifocal Leukoencephalopathy
Inform patients that PML has occurred in patients who received ocrelizumab, and may happen with OCREVUS ZUNOVO. 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 healthcare provider 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 (5.3)].
Malignancies
Advise patients that an increased risk of malignancy, including breast cancer, may exist with OCREVUS ZUNOVO. Advise patients that they should follow standard breast cancer screening guidelines [see Warnings and Precautions (5.5)].
Immune-Mediated Colitis
Advise patients to promptly contact their healthcare provider if they experience any signs and symptoms of colitis, including diarrhea, abdominal pain, and blood in stool [see Warnings and Precautions (5.6)].
Contraception
Females of childbearing potential should use effective contraception while receiving OCREVUS ZUNOVO and for 6 months after the last injection of OCREVUS ZUNOVO [see Clinical Pharmacology (12.3)]. Instruct patients that if they are pregnant or plan to become pregnant while taking OCREVUS ZUNOVO, they should inform their healthcare provider [see Use in Specific Populations (8.1)].
