2 DOSAGE AND ADMINISTRATION For subcutaneous use only ( 2.1 ) All patients must receive at least one full dose of a rituximab product by intravenous infusion before receiving RITUXAN HYCELA by subcutaneous injection ( 2.1 ). FL/DLBCL: Administer 1,400 mg/23,400 Units (1,400 mg rituximab and 23,400 Units hyaluronidase human) subcutaneously according to recommended schedule ( 2.2 , 2.3 ). CLL: Administer 1,600 mg/26,800 Units (1,600 mg rituximab and 26,800 Units hyaluronidase human) subcutaneously according to recommended schedule ( 2.4 ). Premedicate with acetaminophen and antihistamine before each dose; in addition, consider premedication with glucocorticoids ( 2.5 , 5.4 ) Administer specified volume into subcutaneous tissue of abdomen: ( 2.6 ) 11.7 mL from 1,400 mg/23,400 Units vial over approximately 5 minutes. 13.4 mL from 1,600 mg/26,800 Units vial over approximately 7 minutes. Observe 15 minutes following administration 2.1 Important Dosing Information RITUXAN HYCELA is for subcutaneous use only. RITUXAN HYCELA should only be administered by a healthcare professional with appropriate medical support to manage severe reactions that can be fatal if they occur. All patients must first receive at least one full dose of a rituximab product by intravenous infusion without experiencing severe adverse reactions before starting treatment with RITUXAN HYCELA. If patients are not able to receive one full dose by intravenous infusion, they should continue subsequent cycles with a rituximab product by intravenous infusion and not switch to RITUXAN HYCELA until a full intravenous dose is successfully administered [see Warnings and Precautions (5.4) ]. Refer to the prescribing information for a rituximab product for intravenous infusion for additional information. Premedicate before each dose of RITUXAN HYCELA [see Dosage and Administration (2.5) ] . Dose reductions of RITUXAN HYCELA are not recommended. When RITUXAN HYCELA is given in combination with chemotherapy dose,…

12.2 Pharmacodynamics Peripheral B-cell counts declined to levels below normal following a dose of rituximab by intravenous infusion. In patients treated with rituximab for hematological malignancies, B cell recovery began within 6 months of treatment and generally returned to normal levels within 12 months after completion of therapy, although in some patients this may take longer. Follicular Lymphoma (FL) Peripheral B-cell counts decline to levels below normal following the first cycle of rituximab and are maintained during treatment with RITUXAN HYCELA. After stopping RITUXAN HYCELA treatment, B-cell repletion followed similar kinetics to that of rituximab with B-cell repletion beginning after 6 months of stopping treatment, although in some patients this may take longer. Chronic Lymphocytic Leukemia (CLL) Following the first cycle of treatment of rituximab, B-cells begin to deplete, with 28% of patients B-cell depleted at pre-dose Cycle 2 in the SAWYER study. An increase in the proportion of B-cell depleted patients was observed with subsequent cycles of RITUXAN HYCELA and by Cycle 6, 96% of patients were depleted. Patients remained B-cell depleted until the month 9 follow-up visit, where signs of repletion were seen.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Mucocutaneous reactions [see Warnings and Precautions (5.1) ] Hepatitis B reactivation including fulminant hepatitis [see Warnings and Precautions (5.2) ] Progressive multifocal leukoencephalopathy [see Warnings and Precautions (5.3) ] Hypersensitivity and other administration reactions [see Warnings and Precautions (5.4) ] Tumor lysis syndrome [see Warnings and Precautions (5.5) ] Infections [see Warnings and Precautions (5.6) ] Cardiac arrhythmias [see Warnings and Precautions (5.7) ] Renal toxicity [see Warnings and Precautions (5.8) ] Bowel obstruction and perforation [see Warnings and Precautions (5.9) ] Most common adverse reactions (incidence of ≥ 20%) are: ( 6.1 ) FL: infections, neutropenia, nausea, constipation, cough, and fatigue DLBCL: infections, neutropenia, alopecia, nausea, and anemia CLL: infections, neutropenia, nausea, thrombocytopenia, pyrexia, vomiting, and injection site erythema 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 reaction 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. The data described below reflect exposure to RITUXAN HYCELA in 892 patients in four controlled trials with exposures ranging from a single injection up to 27 months of treatment. The population included 382 patients with follicular lymphoma (FL), 369 patients with diffuse large B-cell lymphoma (DLBCL), and 141 patients with chronic lymphocytic leukemia (CLL). The median age was 60 years (range: 18–85 years, 53% were male, and 84% were White. In the SABRINA study patients with FL received a full dose of a rituximab product by…

5 WARNINGS AND PRECAUTIONS Hypersensitivity and other administration reactions: Local cutaneous reactions may occur more than 24 hours after administration. Interrupt injection if severe reaction develops. Premedicate before injection. ( 5.4 ) Tumor lysis syndrome: Administer aggressive intravenous hydration, anti hyperuricemic agents, monitor renal function. ( 5.5 ) Infections: Withhold and institute appropriate anti-infective therapy. ( 5.6 ) Cardiac adverse reactions: Discontinue in case of serious or life-threatening events. ( 5.7 ) Renal toxicity: Discontinue in patients with rising serum creatinine or oliguria.

( 5.9 ) Immunizations: Live virus vaccinations prior to or during treatment not recommended. ( 5.10 ) Embryo-Fetal toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and use of effective contraception. ( 5.11 ) 5.1 Severe Mucocutaneous Reactions Mucocutaneous reactions, some with fatal outcome, can occur in patients treated with rituximab-containing products, including RITUXAN HYCELA. These reactions include paraneoplastic pemphigus, Stevens-Johnson syndrome, lichenoid dermatitis, vesiculobullous dermatitis, and toxic epidermal necrolysis. Discontinue RITUXAN HYCELA in patients who experience a severe mucocutaneous reaction. The safety of re-administration of a rituximab-containing product, including RITUXAN HYCELA, to patients with severe mucocutaneous reactions has not been determined . 5.2 Hepatitis B Virus Reactivation Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure and death, can occur in patients treated with drugs classified as CD20-directed cytolytic antibodies, including rituximab-containing products. HBV reactivation is defined as an abrupt increase in HBV replication manifesting as a rapid increase in serum HBV DNA…
