TRUXIMA- rituximab injection, solution
Cephalon, Inc.

WARNING: FATAL INFUSION-RELATED REACTIONS, SEVERE MUCOCUTANEOUS REACTIONS, HEPATITIS B VIRUS REACTIVATION and PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY (PML)

Infusion-Related Reactions

Administration of rituximab products, including TRUXIMA, can result in serious, including fatal, infusion-related reactions. Deaths within 24 hours of rituximab infusion have occurred. Approximately 80% of fatal infusion-related reactions occurred in association with the first infusion. Monitor patients closely. Discontinue TRUXIMA infusion for severe reactions and provide medical treatment for Grade 3 or 4 infusion-related reactions [see Warnings and Precautions (5.1), Adverse Reactions (6.1)].

Severe Mucocutaneous Reactions

Severe, including fatal, mucocutaneous reactions can occur in patients receiving rituximab products [see Warnings and Precautions (5.2) ].

Hepatitis B Virus (HBV) Reactivation

HBV reactivation can occur in patients treated with rituximab products, in some cases resulting in fulminant hepatitis, hepatic failure, and death. Screen all patients for HBV infection before treatment initiation, and monitor patients during and after treatment with TRUXIMA. Discontinue TRUXIMA and concomitant medications in the event of HBV reactivation [see Warnings and Precautions (5.3) ].

Progressive Multifocal Leukoencephalopathy (PML), including fatal PML, can occur in patients receiving rituximab products [see Warnings and Precautions (5.4) and Adverse Reactions (6.1)].

1 INDICATIONS AND USAGE

1.1 Non–Hodgkin’s Lymphoma (NHL)

TRUXIMA (rituximab-abbs) is indicated for the treatment of adult patients with:

  • Relapsed or refractory, low-grade or follicular, CD20-positive, B-cell NHL as a single agent.
  • Previously untreated follicular, CD20-positive, B-cell NHL in combination with first line chemotherapy and, in patients achieving a complete or partial response to a rituximab product in combination with chemotherapy, as single-agent maintenance therapy.
  • Non-progressing (including stable disease), low-grade, CD20-positive, B-cell NHL as a single agent after first-line cyclophosphamide, vincristine, and prednisone (CVP) chemotherapy.
  • Previously untreated diffuse large B-cell, CD20-positive NHL in combination with cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) or other anthracycline-based chemotherapy regimens.

1.2 Chronic Lymphocytic Leukemia (CLL)

TRUXIMA is indicated, in combination with fludarabine and cyclophosphamide (FC), for the treatment of adult patients with previously untreated and previously treated CD20-positive CLL.

1.3 Rheumatoid Arthritis (RA)

TRUXIMA, in combination with methotrexate, is indicated for the treatment of adult patients with moderately- to severely-active rheumatoid arthritis who have had an inadequate response to one or more TNF antagonist therapies.

1.4 Granulomatosis with Polyangiitis (GPA) (Wegener’s Granulomatosis) and Microscopic Polyangiitis (MPA)

TRUXIMA, in combination with glucocorticoids, is indicated for the treatment of adult patients with Granulomatosis with Polyangiitis (GPA) (Wegener’s Granulomatosis) and Microscopic Polyangiitis (MPA).

2 DOSAGE AND ADMINISTRATION

2.1 Important Dosing Information

Administer only as an Intravenous Infusion [see Dosage and Administration (2.8) ].

Do not administer as an intravenous push or bolus. TRUXIMA should only be administered by a healthcare professional with appropriate medical support to manage severe infusion-related reactions that can be fatal if they occur [see Warnings and Precautions (5.1)].

Premedicate before each infusion [see Dosage and Administration (2.7) ].

Prior to First Infusion: Screen all patients for HBV infection by measuring HBsAg and anti-HBc before initiating treatment with TRUXIMA [see Warnings and Precautions (5.3)]. Obtain complete blood counts (CBC) including platelets prior to the first dose.

During TRUXIMA Therapy: In patients with lymphoid malignancies, during treatment with TRUXIMA monotherapy, obtain complete blood counts (CBC) with differential and platelet counts prior to each TRUXIMA course. During treatment with TRUXIMA and chemotherapy, obtain CBC with differential and platelet counts at weekly to monthly intervals and more frequently in patients who develop cytopenias [see Adverse Reactions (6.1) ]. In patients with RA, GPA or MPA, obtain CBC with differential and platelet counts at two to four month intervals during TRUXIMA therapy. Continue to monitor for cytopenias after final dose and until resolution.

  • First Infusion: Initiate infusion at a rate of 50 mg/hr. In the absence of infusion toxicity, increase infusion rate by 50 mg/hr increments every 30 minutes, to a maximum of 400 mg/hr.
  • Subsequent Infusions:
    Standard Infusion: Initiate infusion at a rate of 100 mg/hr. In the absence of infusion toxicity, increase rate by 100 mg/hr increments at 30-minute intervals, to a maximum of 400 mg/hr.

For previously untreated follicular NHL and DLBCL patients:

If patients did not experience a Grade 3 or 4 infusion related adverse event during Cycle 1, a 90-minute infusion can be administered in Cycle 2 with a glucocorticoid-containing chemotherapy regimen.

Initiate at a rate of 20% of the total dose given in the first 30 minutes and the remaining 80% of the total dose given over the next 60 minutes. If the 90-minute infusion is tolerated in Cycle 2, the same rate can be used when administering the remainder of the treatment regimen (through Cycle 6 or 8).

Patients who have clinically significant cardiovascular disease or who have a circulating lymphocyte count ≥5000/mm3 before Cycle 2 should not be administered the 90-minute infusion [see Clinical Studies (14.4) ].

2.2 Recommended Dose for Non-Hodgkin’s Lymphoma (NHL)

The recommended dose is 375 mg/m2 as an intravenous infusion according to the following schedules:

  • Relapsed or Refractory, Low-Grade or Follicular, CD20-Positive, B-Cell NHL
    Administer once weekly for 4 or 8 doses.
  • Retreatment for Relapsed or Refractory, Low-Grade or Follicular, CD20-Positive, B-Cell NHL
    Administer once weekly for 4 doses.
  • Previously Untreated, Follicular, CD20-Positive, B-Cell NHL
    Administer on Day 1 of each cycle of chemotherapy for up to 8 doses. In patients with complete or partial response, initiate TRUXIMA maintenance eight weeks following completion of a rituximab product in combination with chemotherapy. Administer TRUXIMA as a single-agent every 8 weeks for 12 doses.
  • Non-progressing, Low-Grade, CD20-Positive, B-Cell NHL, after first-line CVP chemotherapy
    Following completion of 6–8 cycles of CVP chemotherapy, administer once weekly for 4 doses at 6-month intervals to a maximum of 16 doses.
  • Diffuse Large B-Cell NHL
    Administer on Day 1 of each cycle of chemotherapy for up to 8 infusions.

2.3 Recommended Dose for Chronic Lymphocytic Leukemia (CLL)

The recommended dose is:

  • 375 mg/m2 the day prior to the initiation of FC chemotherapy, then 500 mg/m2 on Day 1 of cycles 2-6 (every 28 days).

2.4 Recommended Dose as a Component of Zevalin® for treatment of NHL

  • When used as part of the Zevalin therapeutic regimen, infuse 250 mg/m2 in accordance with the Zevalin package insert. Refer to the Zevalin package insert for full prescribing information regarding the Zevalin therapeutic regimen.

2.5 Recommended Dose for Rheumatoid Arthritis (RA)

  • Administer TRUXIMA as two-1000 mg intravenous infusions separated by 2 weeks.
  • Glucocorticoids administered as methylprednisolone 100 mg intravenous or its equivalent 30 minutes prior to each infusion are recommended to reduce the incidence and severity of infusion-related reactions.
  • Subsequent courses should be administered every 24 weeks or based on clinical evaluation, but not sooner than every 16 weeks.
  • TRUXIMA is given in combination with methotrexate.
