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).

The overall exposure in the controlled treatment period was 1416 patient-years, with median treatment duration of 3 years.
