Each vial contains 300 mg of ocrelizumab in 10 mL at a concentration of 30 mg/mL. The final drug concentration after dilution is approximately 1.2 mg/mL.

Ocrelizumab is a recombinant humanised anti-CD20 monoclonal antibody produced in Chinese Hamster Ovary cells by recombinant DNA technology.

For the full list of excipients, see section 6.1.

3. PHARMACEUTICAL FORM

Concentrate for solution for infusion.

Clear to slightly opalescent, and colourless to pale brown solution.

4. CLINICAL PARTICULARS4.1 Therapeutic indications

Ocrevus is indicated for the treatment of adult patients with relapsing forms of multiple sclerosis (RMS) with active disease defined by clinical or imaging features (see section 5.1).

Ocrevus is indicated for the treatment of adult patients with early primary progressive multiple sclerosis (PPMS) in terms of disease duration and level of disability, and with imaging features characteristic of inflammatory activity (see section 5.1).

4.2 Posology and method of administration

Ocrevus treatment should be initiated and supervised by specialised physicians experienced in the diagnosis and treatment of neurological conditions and who have access to appropriate medical support to manage severe reactions such as serious infusion-related reactions (IRRs).

Premedication for infusion-related reactions

The following two premedications must be administered prior to each Ocrevus infusion to reduce the frequency and severity of IRRs (see Infusion-related reactions in section 4.4 for additional steps to reduce IRRs):

• • 100 mg intravenous methylprednisolone (or an equivalent) approximately 30 minutes prior to

each Ocrevus infusion;

• • antihistamine approximately 30–60 minutes prior to each Ocrevus infusion;

In addition, premedication with an antipyretic (e.g paracetamol) may also be considered approximately 30–60 minutes prior to each Ocrevus infusion.

Posology:

Initial Dose

The initial 600 mg dose is administered as two separate intravenous infusions; first as a 300 mg infusion, followed 2 weeks later by a second 300 mg infusion (Table 1).

Subsequent Doses

Subsequent doses of Ocrevus thereafter are administered as a single 600 mg intravenous infusion every 6 months (Table 1).The first subsequent dose of 600 mg should be administered six months after the first infusion of the initial dose.

If patients did not experience a serious infusion-related reaction (IRR) with any previous Ocrevus infusion, a shorter (2-hour) infusion can be administered for subsequent doses (Table 1, Option 2).

A minimum interval of 5 months should be maintained between each dose of Ocrevus.

Infusion Adjustments in case of IRRs

In case of IRRs during any infusion, see the following adjustments. Additional information on IRRs can be found in section 4.4.

Life-threatening IRRs

If there are signs of a life threatening or disabling IRR during an infusion, such as acute hypersensitivity or acute respiratory distress syndrome, the infusion must be stopped immediately and the patient should receive appropriate treatment. Ocrevus must be permanently discontinued in these patients (see section 4.3).

Severe IRRs

If a patient experiences a severe IRR (such as dyspnea) or a complex of flushing, fever, and throat pain symptoms, the infusion should be interrupted immediately and the patient should receive symptomatic treatment. The infusion should be restarted only after all symptoms have resolved. The initial infusion rate at restart should be half of the infusion rate at the time of onset of the reaction. No infusion adjustment is necessary for subsequent new infusions, unless the patient experiences an IRR.

Mild to Moderate IRRs

If a patient experiences a mild to moderate IRR (e.g. headache), the infusion rate should be reduced to half the rate at the onset of the event. This reduced rate should be maintained for at least 30 minutes. If tolerated, the infusion rate may then be increased according to the patient’s initial infusion rate. No infusion adjustment is necessary for subsequent new infusions, unless the patient experiences an IRR.

Dose Modifications during Treatment

The above examples of dose interruption and slowing (for mild/moderate and severe IRRs) will result in a change in the infusion rate and increase the total duration of the infusion, but not the total dose. No dose reductions of Ocrevus are recommended.

Delayed or Missed Doses

If an infusion of Ocrevus is missed, it should be administered as soon as possible; do not wait until the next planned dose. The treatment interval of 6 months (with a minimum of 5 months) for Ocrevus should be maintained between doses (see Table 1).

Special Populations

Adults over 55 years old and elderly population

Based on the limited data available (see section 5.1 and section 5.2), no posology adjustment is needed in patients over 55 years of age. Patients enrolled in the ongoing clinical trials continue to be dosed with 600 mg ocrelizumab every six months after they become 55 and older.

Renal Impairment

The safety and efficacy of Ocrevus in patients with renal impairment has not been formally studied. Patients with mild renal impairment were included in clinical trials. There is no experience in patients with moderate and severe renal impairment. Ocrevus is a monoclonal antibody and cleared via catabolism (i.e. breakdown into peptides and amino acids), and a change in dose is not expected to be required for patients with renal impairment (see section 5.2).

Hepatic Impairment

The safety and efficacy of Ocrevus in patients with hepatic impairment has not been formally studied. Patients with mild hepatic impairment were included in clinical trials. There is no experience in patients with moderate and severe hepatic impairment. Ocrevus is a monoclonal antibody and cleared via catabolism (rather than hepatic metabolism), and a change in dose is not expected to be required for patients with hepatic impairment (see section 5.2).

Paediatric population

The safety and efficacy of Ocrevus in children and adolescents aged 0 to 18 years has not yet been established. No data are available.

Method of Administration

After dilution, Ocrevus is administered as an intravenous infusion through a dedicated line. Ocrevus infusions should not be administered as an intravenous push or bolus.

1.2 mg/mL.For instructions on dilution of the medicinal product before administration see section 6.6.

Patients should be monitored during the infusion and for at least one hour after the completion of the infusion (see section 4.4).

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

• • Current active infection (see section 4.4)
• • Patients in a severely immunocompromised state (see section 4.4 ).
• • Known active malignancies (see section 4.4)

4.4 Special warnings and precautions for use

Traceability

In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

Infusion-Related Reactions (IRRs)

Ocrevus is associated with IRRs, which may be related to cytokine release and/or other chemical mediators.

Symptoms of IRRs may occur during any infusion, but have been more frequently reported during the first infusion. IRRs can occur within 24 hours of the infusion (see section 4.8). These reactions may present as pruritus, rash, urticaria, erythema, throat irritation, oropharyngeal pain, dyspnoea, pharyngeal or laryngeal oedema, flushing, hypotension, pyrexia, fatigue, headache, dizziness, nausea, tachycardia and anaphylaxis.

Before the infusion:

• • Management of severe reactions: Appropriate resources for the management of severe reactions such as serious IRR, hypersensitivity reactions and/or anaphylactic reactions should be available.
• • Premedication: Patients must receive premedication to reduce the frequency and severity of

IRRs (see section 4.2.).

During the infusion:

• • The following measures need to be taken for patients who experience severe pulmonary symptoms, such as bronchospasm or asthma exacerbation:

• – their infusion must be interrupted immediately and permanently

• – symptomatic treatment must be administered

• – the patient must be monitored until the pulmonary symptoms have resolved because initial improvement of clinical symptoms could be followed by deterioration

• • Hypersensitivity may be difficult to distinguish from an IRR in terms of symptoms. If a hypersensitivity reaction is suspected during infusion, the infusion must be stopped immediately and permanently (see ‘Hypersensitivity Reactions’ below).

After the infusion:

• • Patients treated with Ocrevus should be observed for at least one hour after the completion of the infusion for any symptom of IRR.
• • Physicians should alert patients that an IRR can occur within 24 hours of infusion.

For guidance regarding posology for patients experiencing IRR symptoms see section 4.2.

Hypersensitivity Reactions

A hypersensitivity reaction could also occur (acute allergic reaction to medicinal product). Type 1 acute hypersensitivity reactions (IgE-mediated) may be clinically indistinguishable from IRR symptoms.

A hypersensitivity reaction may present during any infusion, although typically would not present during the first infusion. For subsequent infusions, more severe symptoms than previously experienced, or new severe symptoms, should prompt consideration of a potential hypersensitivity reaction. Patients with known IgE mediated hypersensitivity to ocrelizumab must not be treated (see section 4.3).

Infection

Ocrevus administration must be delayed in patients with an active infection until the infection is resolved.

It is recommended to verify the patient’s immune status before dosing since severely immunocompromised patients (e.g. with lymphopenia, neutropenia, hypogammaglobu­linemia) should not be treated (see sections 4.3 and 4.8).

The overall proportion of patients experiencing a serious infection was similar to comparators (see section 4.8). The frequency of grade 4 (life-threatening) and grade 5 (fatal) infections was low in all treatment groups, but in PPMS it was higher with Ocrevus compared with placebo for life-threatening (1.6% vs 0.4%) and fatal (0.6% vs 0%) infections. All life-threatening infections resolved without discontinuing ocrelizumab.

In PPMS, patients with swallowing difficulties are at a higher risk of aspiration pneumonia. Ocrevus treatment may further increase the risk of severe pneumonia in these patients. Physicians should take prompt action for patients presenting with pneumonia.

Progressive multifocal leukoencephalopathy (PML)

A risk of PML cannot be ruled-out since John Cunningham (JC) virus infection resulting in PML has been observed in patients treated with anti-CD20 antibodies and other MS therapies, and associated with risk factors (patient population e.g. lymphopenia, advanced age, polytherapy with immunosuppres­sants).

Physicians should be vigilant for the early signs and symptoms of PML, which can include any new onset, or worsening of neurological signs or symptoms, as these can be similar to MS disease.

If PML is suspected, dosing with Ocrevus must be withheld. Evaluation including Magnetic Resonance Imaging (MRI) scan preferably with contrast (compared with pre-treatment MRI), confirmatory cerebro-spinal fluid (CSF) testing for John Cunningham (JC) Viral Deoxyribonucleic acid (DNA) and repeat neurological assessments, should be considered. If PML is confirmed, treatment must be discontinued permanently.

Hepatitis B reactivation

Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure and death, has been reported in patients treated with anti-CD20 antibodies.

HBV screening should be performed in all patients before initiation of treatment with Ocrevus as per local guidelines. Patients with active HBV (i.e. an active infection confirmed by positive results for HBsAg and anti HB testing) should not be treated with Ocrevus. Patients with positive serology (i.e. negative for HBsAg and positive for HB core antibody (HBcAb +); carriers of HBV (positive for surface antigen, HBsAg+) should consult liver disease experts before start of treatment and should be monitored and managed following local medical standards to prevent hepatitis B reactivation.

Late neutropenia

Cases of late onset of neutropenia have been reported. Although some cases were Grade 3 or 4, the majority of the cases were Grade 1 or 2. Cases of late onset of neutropenia have been reported at least 4 weeks after the latest Ocrevus infusion. In patients with signs and symptoms of infection, measurement of blood neutrophils is recommended (see section 4.8).

Malignancies

An increased number of malignancies (including breast cancers) have been observed in clinical trials in patients treated with ocrelizumab, compared to control groups. However, the incidence was within the background rate expected for an MS population. Individual benefit risk should be considered in patients with known risk factors for malignancies and in patients who are being actively monitored for recurrence of malignancy. Patients with a known active malignancy should not be treated with Ocrevus (see section 4.3). Patients should follow standard breast cancer screening per local guidelines. Please see section 4.2 for populations not studied.

In the controlled period of the clinical trials, the incidence of non-melanoma skin cancers was low and there was no imbalance between treatment groups. An increase in incidence was observed between years 3 and 4 of treatment due to basal cell carcinoma, which was not observed in subsequent years. The incidence remains within the background rate expected for an MS population.

Treatment of severely immunocompromised patients

Patients in a severely immunocompromised state must not be treated until the condition resolves (see section 4.3.).

In other auto-immune conditions, use of Ocrevus concomitantly with immunosuppressive medications (e.g. chronic corticosteroids, non-biologic and biologic disease-modifying antirheumatic drugs [DMARDS], mycophenolate mofetil, cyclophosphamide, azathioprine) resulted in an increase of serious infections, including opportunistic infections. Infections included and were not limited to atypical pneumonia and pneumocystis jirovecii pneumonia, varicella pneumonia, tuberculosis, histoplasmosis. In rare cases, some of these infections were fatal. An exploratory analysis identified the following factors associated with risk of serious infections: higher doses of Ocrevus than recommended in MS, other comorbidities, and chronic use of immunosuppres­sants/corticos­teroids.

It is not recommended to use other immunosuppressives concomitantly with Ocrevus except corticosteroids for symptomatic treatment of relapses. Knowledge is limited as to whether concomitant steroid use for symptomatic treatment of relapses is associated with an increased risk of infections in clinical practice. In the ocrelizumab MS pivotal studies the administration of corticosteroids for the treatment of relapse was not associated with an increased risk of serious infection.

When initiating Ocrevus after an immunosuppressive therapy or initiating an immunosuppressive therapy after Ocrevus, the potential for overlapping pharmacodynamic effects should be taken into consideration (see section 5.1 Pharmacody­namic effects). Caution should be exercised when prescribing Ocrevus taking into consideration the pharmacodynamics of other disease modifying MS therapies.

Vaccinations

The safety of immunisation 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 not until B-cell repletion (in clinical trials, the median time for B-cell repletion was 72 weeks). See section 5.1.

In a randomized open-label study, RMS patients were able to mount humoral responses, although decreased, to tetanus toxoid, 23-valent pneumococcal polysaccharide with or without a booster vaccine, keyhole limpet hemocyanin neoantigen, and seasonal influenza vaccines. See section 4.5 and 5.1.

It is recommended to vaccinate patients treated with Ocrevus with seasonal influenza vaccines that are inactivated.

Physicians should review the immunisation status of patients being considered for treatment with Ocrevus. Patients who require vaccination should complete their immunisation at least 6 weeks prior to initiation of Ocrevus.

See section 4.5 and 5.1 for further information about vaccinations.

Exposure in utero to ocrelizumab and vaccination of neonates and infants with live or live attenuated vaccines

Due to the potential depletion of B cells in infants of mothers who have been exposed to Ocrevus during pregnancy, it is recommended that vaccination with live or live-attenuated vaccines should be delayed until B-cell levels have recovered; therefore, measuring CD19-positive B-cell levels, in neonates and infants, prior to vaccination is recommended

It is recommended that all vaccinations other than live or live-attenuated should follow the local immunisation schedule and measurement of vaccine-induced response titers should be considered to check whether individuals have mounted a protective immune response because the efficacy of the vaccination may be decreased.

The safety and timing of vaccination should be discussed with the infant’s physician (see section 4.6).

Sodium

This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e. it is essentially sodium-free.

4.5 Interaction with other medicinal products and other forms of interaction

No formal drug interaction studies have been performed, as no drug interactions are expected via cytochrome P450 enzymes, other metabolising enzymes or transporters.

Vaccinations

The safety of immunisation with live or live-attenuated vaccines, following Ocrevus therapy has not been studied.

Data are available on the effects of tetanus toxoid, 23-valent pneumococcal polysaccharide, keyhole limpet hemocyanin neoantigen, and seasonal influenza vaccines in patients receiving Ocrevus. See section 4.4 and 5.1.

After treatment with Ocrevus over 2 years, the proportion of patients with positive antibody titers against S. pneumoniae, mumps, rubella and varicella were generally similar to the proportions at baseline.

Immunosuppres­sants

It is not recommended to use other immunosuppressives concomitantly with Ocrevus except corticosteroids for symptomatic treatment of relapses.

See section 4.4 ‘Treatment of severely immunocompromised patients’ for information about the use of immunosuppressants before, during or after Ocrevus treatment.

4.6 Fertility, pregnancy and lactation

Women of child bearing potential

Women of child bearing potential should use contraception while receiving Ocrevus and for 12 months after the last infusion of Ocrevus (see below and section 5.1 and 5.2).

Pregnancy

Ocrevus is a humanised monoclonal antibody of an immunoglobulin G1 subtype and immunoglobulins are known to cross the placental barrier.

There is a limited amount of data from the use of Ocrevus in pregnant women. Postponing vaccination with live or live-attenuated vaccines should be considered for neonates and infants born to mothers who have been exposed to Ocrevus in utero. No B cell count data have been collected in neonates and infants exposed to ocrelizumab and the potential duration of B-cell depletion in neonates and infants is unknown (see section 4.4).

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

Animal studies (embryo-foetal toxicity) do not indicate teratogenic effects. B-cell depletion in utero was detected. Reproductive toxicity was observed in pre and post natal development studies (see section 5.3).

Ocrevus should be avoided during pregnancy unless the potential benefit to the mother outweighs the potential risk to the foetus.

Breast-feeding

It is unknown whether ocrelizumab/me­tabolites are excreted in human milk. Available pharmacodynamic/to­xicological data in animals have shown excretion of ocrelizumab in milk (for details see section 5.3). A risk to neonates and infants cannot be excluded. Women should be advised to discontinue breast-feeding during Ocrevus therapy.

Fertility

Preclinical data reveal no special hazards for humans based on studies of male and female fertility in cynomologous monkeys.

4.7 Effects on ability to drive and use machines

Ocrevus has no or negligible influence on the ability to drive and use machines.

4.8 Undesirable effects

Summary of the safety profile

The most important and frequently reported adverse drug reactions (ADRs) were IRRs and infections. See section 4.4 and section 4.8 (subsection ‘Description of selected adverse reactions’) for further details.

Tabulated list of adverse reactions

The overall safety profile of Ocrevus in Multiple Sclerosis is based on data from patients from pivotal clinical trials in MS (RMS and PPMS).

The table 2 summarises the ADRs that have been reported in association with the use of Ocrevus in 1311 patients (3054 patient years) during the controlled treatment periods of MS clinical trials.

Frequencies are defined as very common (> 1/10), common (> 1/100 to < 1/10), uncommon (> 1/1,000 to < 1/100), rare (> 1/10,000 to < 1/1,000), very rare (< 1/10,000) and not known (cannot be estimated from the available data). Within each System Organ Class, the adverse reactions are presented in order of decreasing frequency.

Description of selected adverse reactions

Infusion-related reactions

Across the RMS and PPMS trials, symptoms associated with IRRs included, but are not limited to: pruritus, rash, urticaria, erythema, flushing, hypotension, pyrexia, fatigue, headache, dizziness, throat irritation, oropharyngeal pain, dyspnoea, pharyngeal or laryngeal oedema, nausea, tachycardia. In controlled trials there were no fatal IRRs. In addition, symptoms of IRR in the post-marketing setting included anaphylaxis.

In active-controlled (RMS) clinical trials, IRR was the most common adverse event in patients treated with Ocrevus with an overall incidence of 34.3% compared with an incidence of 9.9% in the interferon beta-1a treatment group (placebo infusion). The incidence of IRRs was highest during the Dose 1, infusion 1 (27.5%) and decreased over time to <10% at Dose 4. The majority of IRRs in both treatment groups were mild to moderate. 21,7% and 10.1% of Ocrevus treated patients experienced mild and moderate IRRs respectively, 2.4% experienced severe IRRs and 0.1% experienced lifethreatening IRRs. See section 4.4.

In the placebo-controlled (PPMS) clinical trial, IRR was the most common adverse event in patients treated with Ocrevus with an overall incidence of 40.1% compared with an incidence of 25.5% in the placebo group. The incidence of IRRs was highest during Dose 1, infusion 1 (27.4%,) and decreased with subsequent doses to <10% at Dose 4. A greater proportion of patients in each group experienced IRRs with the first infusion of each dose compared with the second infusion of that dose. The majority of IRRs were mild to moderate. 26.7% and 11.9% of Ocrevus treated patients experienced mild and moderate IRRs respectively, 1.4% experienced severe IRRs. There were no life-threatening IRRs. See section 4.4.

Alternative Shorter Infusion of Subsequent Doses

In a study (MA30143 Shorter Infusion Substudy) designed to characterise the safety profile of shorter (2-hour) Ocrevus infusions in patients with Relapsing-Remitting Multiple Sclerosis, the incidence, intensity, and types of symptoms of IRRs were consistent with those of infusions administered over 3.5 hours (see section 5.1 Pharmacody­namic properties). The overall number of interventions needed was low in both infusion groups, however, more interventions (slowing down or temporary interruptions) were needed to manage IRRs in the shorter (2-hour) infusion group compared to the 3.5-hour infusion group (8.7% vs. 4.8%, respectively).

Infection

In the active-controlled studies in RMS, infections occurred in 58.5% of patients receiving Ocrevus vs 52.5% of patients receiving interferon beta 1a. Serious infections occurred in 1.3% of patients receiving Ocrevus vs 2.9% of patients receiving interferon beta 1a. In the placebo-controlled study in PPMS, infections occurred in 72.2% of patients receiving Ocrevus vs 69.9% of patients receiving placebo. Serious infections occurred in 6.2% of patients receiving Ocrevus vs 6.7% of patients receiving placebo. An increase in the rate of serious infections was observed in RMS between Years 2 and 3, but not in subsequent years. No increase was observed in PPMS.

Respiratory Tract Infections

The proportion of respiratory tract infections was higher in Ocrevus treated patients compared to interferon beta-1-a and placebo.

In the RMS clinical trials, 39.9% of Ocrevus treated patients and 33.2% interferon beta-1-a treated patients experienced an upper respiratory tract infection and 7.5% of Ocrevus treated patients and 5.2% of interferon beta-1-a treated patients experienced a lower respiratory tract infection.

In the PPMS clinical trial, 48.8% of Ocrevus treated patients and 42.7% of patients who received placebo experienced an upper respiratory tract infection, and 9.9% of Ocrevus treated patients and 9.2% of patients who received placebo experienced a lower respiratory tract infection.

The respiratory tract infections reported in patients treated with Ocrevus were predominately mild to moderate (80 – 90 %).

Herpes

In active-controlled (RMS) clinical trials, herpes infections were reported more frequently in Ocrevus-treated patients than in interferon-beta-1a 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 and patients recovered with treatment by standard therapies.

In the placebo-controlled (PPMS) clinical trial, a higher proportion of patients with oral herpes (2.7% vs 0.8%) were observed in the Ocrevus treatment arm.

Laboratory Abnormalities

Immunoglobulins

Treatment with Ocrevus resulted in a decrease in total immunoglobulins over the controlled period of the studies, mainly driven by reduction in IgM. Clinical trial data have shown an association between decreased levels of IgG (and less so for IgM or IgA) and serious infections.

Lymphocytes

In RMS, a decrease in lymphocyte < LLN was observed in 20.7% of Ocrevus patients compared with 32.6% of patients treated with interferon beta-1a. In PPMS, a decrease in lymphocytes <LLN was observed in 26.3% of Ocrevus treated patients vs 11.7% of placebo-treated patients.

The majority of these decreases reported in Ocrevus treated patients were Grade 1 (<LLN –800 cells/mm3) and 2 (between 500 and 800 cells/mm3) in severity. Approximately 1% of the patients in the Ocrevus group had a Grade 3 lymphopenia (between 200 and 500 cells/mm3). None of the patients was reported with Grade 4 lymphopenia (< 200 cells/mm3).

An increased rate of serious infections was observed during episodes of confirmed total lymphocytes counts decrease in ocrelizumab treated patients. The number of serious infections was too low to draw definitive conclusions.

Neutrophils

In the active-controlled (RMS) treatment period, a decrease in neutrophils < LNN was observed in 14.7% of Ocrevus patients compared with 40.9% of patients treated with interferon beta-1a. In the placebo-controlled (PPMS) clinical trial, the proportion of Ocrevus patients presenting decreased neutrophils was higher (12.9 %) than placebo patients (10.0 %); among these a higher percentage of patients (4.3%) in the Ocrevus group had Grade 2 or above neutropenia vs 1.3% in the placebo group; approximately 1% of the patients in the Ocrevus group had Grade 4 neutropenia vs 0% in the placebo group.

The majority of the neutrophil decreases were transient (only observed once for a given patient treated with Ocrevus) and were Grade 1 (between<LLN and 1500 cells/mm3) and 2 (between 1000 and 1500 cells/mm3) in severity. One patient with grade 3 (between 500 and 1000 cells/mm3) and one patient with grade 4 (< 500 cells/mm3) neutropenia required specific treatment with granulocyte-colony stimulating factor, and remained on ocrelizumab after the episode. Neutropenia can occur several months after the administration of Ocrevus (see section 4.4).

Other

One patient, who received 2000 mg of Ocrevus, died of systemic inflammatory response syndrome (SIRS) of unknown etiology, following a magnetic resonance imaging (MRI) examination 12 weeks after the last infusion; an anaphylactoid reaction to the MRI gadolinium-contrast agent could have contributed to the SIRS.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in

4.9 Overdose

There is limited clinical trial experience with doses higher than the approved intravenous dose of Ocrevus. The highest dose tested to date in MS patients is 2000 mg, administered as two 1000 mg intravenous infusions separated by 2 weeks (Phase II dose finding study in RRMS). The adverse drug reactions were consistent with the safety profile for Ocrevus in the pivotal clinical studies.

Please refer to section 4.8 for information about the Systemic Inflammatory Response Syndrome (SIRS) that occurred in a patient treated with Ocrevus 2000 mg.

There is no specific antidote in the event of an overdose; interrupt the infusion immediately and observe the patient for IRRs (see section 4.4).

5. PHARMACOLOGICAL PROPERTIES5.1 Pharmacodynamic properties

Pharmacotherapeutic group: selective immunosuppressants group, ATC code: L04AA36.

Mechanism of Action

Ocrelizumab is a recombinant humanised monoclonal antibody that selectively targets CD20-expressing B cells.

CD20 is a cell surface antigen found on pre-B cells, mature and memory B cells but not expressed on lymphoid stem cells and plasma cells.

The precise mechanisms through which ocrelizumab exerts its therapeutic clinical effects in MS is not fully elucidated but is presumed to involve immunomodulation through the reduction in the number and function of CD20-expressing B cells. Following cell surface binding, ocrelizumab selectively depletes CD20-expressing B cells through antibody-dependent cellular phagocytosis (ADCP), antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and apoptosis. The capacity of B-cell reconstitution and preexisting humoral immunity are preserved. In addition, innate immunity and total T-cell numbers are not affected.

Pharmacodynamic effects

Treatment with Ocrevus leads to rapid depletion of CD19+ B cells in blood by 14 days post treatment (first time-point of assessment) as an expected pharmacologic effect. This was sustained throughout the treatment period. For the B cell counts, CD19 is used, as the presence of Ocrevus interferes with the recognition of CD20 by the assay.

In the Phase III studies, between each dose of Ocrevus, up to 5% of patients showed B-cell repletion (> lower limit of normal (LLN) or baseline) at least at one time point. The extent and duration of B-cell depletion was consistent in the PPMS and RMS trials.

The longest follow up time after the last Ocrevus infusion (Phase II study WA21493, N=51) indicates that the median time to B-cell repletion (return to baseline/LLN whichever occurred first) was 72 weeks (range 27 – 175 weeks). 90% of all patients had their B-cells repleted to LLN or baseline by approximately two and a half years after the last infusion.

Clinical efficacy and safety

Relapsing forms of MS

Efficacy and safety of Ocrevus were evaluated in two randomised, double-blind, double-dummy, active comparator-controlled clinical trials (WA21092 and WA21093), with identical design, in patients with relapsing forms of MS (in accordance with McDonald criteria 2010) and evidence of disease activity (as defined by clinical or imaging features) within the previous two years. Study design and baseline characteristics of the study population are summarised in Table 3.

Demographic and baseline characteristics were well balanced across the two treatment groups. Patients receiving Ocrevus (Group A) were given 600 mg every 6 months (Dose 1 as 2 × 300 mg intravenous infusions, administered 2 weeks apart, and subsequent doses were administered as a single 600 mg intravenous infusion). Patients in Group B were administered Interferon beta-1a (Rebif) 44 mcg via subcutaneous injection 3 times per week.

Pre-specified pooled analysis of WA21092 and WA21093

Results of the pre-specified pooled analyses of time to CDP sustained for at least 12 weeks (40% risk reduction for Ocrevus compared to interferon beta-1a (p=0.0006) were highly consistent with the results sustained for at least 24 weeks (40% risk reduction for Ocrevus compared to interferon beta-1a, p=0.0025).

The studies enrolled patients with active disease. These included both active treatment naive and previously treated inadequate responders, as defined by clinical or imaging features. Analysis of patient populations with differing baseline levels of disease activity, including active and highly active disease, showed that the efficacy of Ocrevus on ARR and 12 week CDP was consistent with the overall population.

Primary Progressive MS

Efficacy and safety of Ocrevus were also evaluated in a randomised, double-blind, placebo-controlled clinical trial in patients with primary progressive MS (Study WA25046) who were early in their disease course according to the main inclusion criteria, i.e. ages 18–55 years, inclusive; EDSS at screening from 3.0 to 6.5 points; disease duration from the onset of MS symptoms less than 10 years in patients with an EDSS at screening <5.0 or less than 15 years in patients with an EDSS at screening >5.0. With regard to disease activity, features characteristic of inflammatory activity, even in progressive MS, can be imaging-related, (i.e. T1 Gd-enhancing lesions and/or active [new or enlarging] T2 lesions). MRI evidence should be used to confirm inflammatory activity in all patients. Patients over 55 years of age were not studied. Study design and baseline characteristics of the study population are presented in Table 5.

Demographic and baseline characteristics were well balanced across the two treatment groups. Cranial MRI showed imaging features characteristic of inflammatory activity either by T1 Gd enhancing lesions or T2 lesions.

During the Phase 3 PPMS study, patients received 600 mg Ocrevus every 6 months as two 300 mg infusions, given two weeks apart, throughout the treatment period. The 600 mg infusions in RMS and the 2 × 300 mg infusions in PPMS demonstrated consistent PK/PD profiles. IRR profiles per infusion were also similar, independent of whether the 600 mg dose was administered as a single 600 mg infusion or as two 300 mg infusions separated by two weeks (see sections 4.8 and 5.2), but due to overall more infusions with the 2 × 300 mg regimen, the total number of IRRs were higher. Therefore, after Dose 1 it is recommended to administer Ocrevus in a 600 mg single infusion (see section 4.2) to reduce the total number of infusions (with concurrent exposure to prophylactic methylprednisolone and an antihistamine) and the related infusion reactions).

Time to onset of Confirmed Disability Prooression (Weeks)

All patients in this analysis had a minimum of 120 weeks of follow-up. The primary analysis is based on all events accrued.

Pre-specified non-powered subgroup analysis of the the primary endpoint suggests that patients who are younger or those with T1 Gd-enhancing lesions at baseline receive a greater treatment benefit than patients who are older or without T1 Gd-enhancing lesions (< 45 years: HR 0.64 [0.45, 0.92], >45 years: HR 0.88 [0.62, 1.26]; with T1 Gd-enhancing lesions at baseline: HR 0.65 [0.40–1.06], without T1 Gd-enhancing lesions at baseline: HR 0.84 [0.62–1.13]).

Moreover, post-hoc analyses suggested that younger patients with T1 Gd-enhancing lesions at baseline have the better treatment effect (< 45 years: HR 0.52 [0.27–1.00]; < 46 years [median age of the WA25046 study]; HR 0.48 [0.25–0.92]; <51 years: HR 0.53 [0.31–0.89]).

Post-hoc analyses were performed in the Extended Controlled Period (ECP), which includes doubleblinded treatment and approximately 9 additional months of controlled follow-up before continuing into the Open-Label Extension (OLE) or until withdrawal from study treatment. The proportion of patients with 24 week Confirmed Disability Progression of EDSS>7.0 (24W-CDP of EDSS>7.0, time to wheelchair) was 9.1% in the placebo group compared to 4.8% in the Ocrevus group at Week 144, resulting in a 47% risk reduction of the time to wheelchair (HR 0.53, [0.31, 0.92]) during the ECP. As these results were exploratory in nature and included data after unblinding, the results should be interpreted with caution.

Shorter Infusion Substudy

The safety of the shorter (2-hour) Ocrevus infusion was evaluated in a prospective, multicenter, randomised, double-blind, controlled, parallel arm substudy to Study MA30143 (Ensemble) in patients with Relapsing-Remitting Multiple Sclerosis that were naïve to other disease modifying treatments. The first dose of Ocrevus was administered as two 300 mg infusions (600 mg total) separated by 14 days. Patients were randomised from their second dose onwards (Dose 2 to 6) in a 1:1 ratio to either the conventional infusion group with Ocrevus infused over approximately 3.5 hours every 24 weeks, or the shorter infusion group with Ocrevus infused over approximately 2 hours every 24 weeks. The randomisation was stratified by region and the dose at which patients were first randomised.

The primary endpoint was the proportion of patients with IRRs occurring during or within 24 hours following the first randomised infusion of Ocrevus. The primary analysis was performed when 580 patients were randomised. The proportion of patients with IRRs occurring during or within 24 hours following the first randomised infusion was 24.6% in the shorter infusion compared to 23.1% in the conventional infusion group. The stratified group difference was similar. Overall, in all randomised doses, the majority of the IRRs were mild or moderate and only two IRRs were severe in intensity, with one severe IRR in each group. There were no life-threatening, fatal, or serious IRRs.

Immunogenicity

Patients in MS trials (WA21092, WA21093 and WA25046) were tested at multiple time points (baseline and every 6 months post treatment for the duration of the trial) for anti-drug antibodies (ADAs). Out of 1311 patients treated with Ocrevus, 12 (~1%) tested positive for treatment-emergent ADAs, of which 2 patients tested positive for neutralising antibodies. The impact of treatment-emergent ADAs on safety and efficacy cannot be assessed given the low incidence of ADA associated with Ocrevus.

Immunisations

In a randomized open-label study in RMS patients (N=102), the percentage of patients with a positive response to tetanus vaccine at 8 weeks after vaccination was 23.9% in the ocrelizumab group compared to 54.5% in the control group (no disease-modifying therapy except interferon-beta).

Geometric mean anti-tetanus toxoid specific antibody titers at 8 weeks were 3.74 and 9.81 IU/ml, respectively. Positive response to >5 serotypes in 23-PPV at 4 weeks after vaccination was 71.6% in the ocrelizumab group and 100% in the control group. In patients treated with ocrelizumab a booster vaccine (13-PCV) given 4 weeks after 23-PPV did not markedly enhance the response to 12 serotypes in common with 23-PPV. The percentage of patients with seroprotective titers against five influenza strains ranged from 20.0–60.0% and 16.7–43.8% pre-vaccination and at 4 weeks post vaccination from 55.6–80.0% in patients treated with ocrelizumab and 75.0–97.0% in the control group , respectively. See sections 4.4 and 4.5.

Paediatric population

The European Medicines Agency has deferred the obligation to submit the results of studies with Ocrevus in one or more subsets of the paediatric population in the treatment of multiple sclerosis. See section 4.2 for information on paediatric use.

5.2 Pharmacokinetic properties

The pharmacokinetics of ocrelizumab in the MS studies were described by a two compartment model with time-dependent clearance, and with PK parameters typical for an IgG1 monoclonal antibody. The overall exposure (AUC over the 24 weeks dosing interval) was identical in the 2 × 300 mg in PPMS and 1 × 600 mg in RMS studies, as expected given an identical dose was administered. Area under the curve (AUCt) after the 4th dose of 600 mg ocrelizumab was 3510 ^g/mL^day, and mean maximum concentration (Cmax) was 212 ^g/mL in RMS (600 mg infusion) and 141 ^g/mL in PPMS (300 mg infusions).

Absorption

Ocrevus is administered as an intravenous infusion. There have been no studies performed with other routes of administration.

Distribution

The population pharmacokinetics estimate of the central volume of distribution was 2.78 L. Peripheral volume and inter-compartment clearance were estimated at 2.68 L and 0.294 L/day.

Biotransformation

The metabolism of Ocrevus has not been directly studied, as antibodies are cleared principally by catabolism (i.e. breakdown into peptides and amino acids).

Elimination

Constant clearance was estimated at 0.17 L/day, and initial time-dependent clearance at 0.0489 L/day which declined with a half-life of 33 weeks. The terminal elimination half-life of ocrelizumab was 26 days.

Pharmacokinetics in Special Populations

Paediatrics

No studies have been conducted to investigate the pharmacokinetics of ocrelizumab in children and adolescents <18 years of age.

Elderly

There are no dedicated PK studies of ocrelizumab in patients >55 years due to limited clinical experience (see section 4.2).

Renal impairment

No formal pharmacokinetic study has been conducted. Patients with mild renal impairment were included in clinical trials and no change in the pharmacokinetics of Ocrevus was observed in those patients. There is no PK information available in patients with moderate or severe renal impairment.

Hepatic impairment

No formal pharmacokinetic study has been conducted. Patients with mild hepatic impairment were included in clinical trials, and no change in the pharmacokinetics was observed in those patients. There is no PK information available in patients with moderate or severe hepatic impairment.

5.3 Preclinical safety data

Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, and embryo-foetal development. Neither carcinogenicity nor mutagenicity studies have been conducted with ocrelizumab.

In two pre- and post-natal development studies in cynomolgus monkeys, administration of ocrelizumab from gestation day 20 to at least parturition was associated with glomerulopathy, lymphoid follicle formation in bone marrow, lymphoplasmacytic renal inflammation, and decreased testicular weight in offspring. The maternal doses administered in these studies resulted in maximum mean serum concentrations (Cmax) that were 4.5– to 21-fold above those anticipated in the clinical setting.

There were five cases of neonatal moribundities, one attributed to weakness due to premature birth accompanied by opportunistic bacterial infection, one due to an infective meningoencephalitis involving the cerebellum of the neonate from a maternal dam with an active bacterial infection (mastitis) and three with evidence of jaundice and hepatic damage, with a viral etiology suspected, possibly a polyomavirus. The course of these five confirmed or suspected infections could have potentially been impacted by B-cell depletion. Newborn offspring of maternal animals exposed to ocrelizumab were noted to have depleted B cell populations during the post natal phase. Measurable levels of ocrelizumab were detected in milk (approximated 0.2% of steady state trough serum levels) during the lactation period.
