Rituxan® (rituximab) is indicated for the treatment of adult patients with Non-Hodgkin’s Lymphoma (NHL):
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 CVP chemotherapy
Previously untreated diffuse large B-cell, CD20-positive NHL in combination with CHOP or other anthracycline-based chemotherapy regimens
Rituxan is indicated for the treatment of adult patients with previously untreated and previously treated CD20-positive Chronic Lymphocytic Leukemia (CLL) in combination with fludarabine and cyclophosphamide (FC)
Rituxan, in combination with methotrexate, is indicated for the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response to one or more TNF antagonist therapies
Rituxan, in combination with glucocorticoids, is indicated for the treatment of adult and pediatric patients 2 years of age and older with Granulomatosis with Polyangiitis (GPA) (Wegener’s Granulomatosis) and Microscopic Polyangiitis (MPA)
Rituxan is indicated for the treatment of adult patients with moderate to severe pemphigus vulgaris (PV)
WARNING: FATAL INFUSION-RELATED REACTIONS, SEVERE MUCOCUTANEOUS REACTIONS, HEPATITIS B VIRUS REACTIVATION and PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY
Infusion-Related Reactions: Rituxan administration can result in serious, including fatal infusion-related reactions. Deaths within 24 hours of Rituxan infusion have occurred. Approximately 80% of fatal infusion reactions occurred in association with the first infusion. Monitor patients closely. Discontinue Rituxan infusion for severe reactions and provide medical treatment for Grade 3 or 4 infusion-related reactions.
Severe Mucocutaneous Reactions: Severe, including fatal, mucocutaneous reactions can occur in patients receiving Rituxan.
Hepatitis B Virus (HBV) Reactivation: HBV reactivation can occur in patients treated with Rituxan, 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 Rituxan. Discontinue Rituxan and concomitant medications in the event of HBV reactivation.
Progressive Multifocal Leukoencephalopathy (PML), including fatal PML, can occur in patients receiving Rituxan.
Tumor Lysis Syndrome: Acute renal failure, hyperkalemia, hypocalcemia, hyperuricemia, or hyperphosphatemia from tumor lysis, some fatal, can occur within 12−24 hours after the first infusion of Rituxan in patients with NHL. Administer aggressive intravenous hydration, anti-hyperuricemic agents, monitor renal function
Infections: Serious, including fatal, bacterial, fungal, and new or reactivated viral infections can occur during and following the completion of Rituxan-based therapy. Withhold Rituxan and institute appropriate anti-infective therapy. Rituxan is not recommended for use in patients with severe, active infections
Cardiovascular Adverse Reactions: Discontinue infusions in case of serious or life-threatening events
Renal Toxicity: Severe, including fatal, renal toxicity can occur after Rituxan administration in patients with NHL. Discontinue in patients with rising serum creatinine or oliguria
Bowel Obstruction and Perforation: Abdominal pain, bowel obstruction and perforation, in some cases leading to death, can occur in patients receiving Rituxan in combination with chemotherapy. Consider and evaluate for abdominal pain, vomiting, or related symptoms
Immunization: Live virus vaccinations prior to or during Rituxan treatment not recommended
Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and use of effective contraception.
Concomitant Use With Biologic Agents and DMARDs Other Than Methotrexate: Patients with RA should be closely observed for signs of infection if biologic agents and/or DMARDs other than methotrexate are used concomitantly. Use of concomitant immunosuppressants other than corticosteroids has not been studied in GPA, MPA, or PV patients exhibiting peripheral B-cell depletion following treatment with Rituxan
Use in Patients With RA Who Had No Prior Inadequate Response to TNF Antagonists: The use of Rituxan in patients with RA who have not had prior inadequate response to one or more TNF antagonists is not recommended.
The most common Grade 3 or 4 adverse reactions in clinical trials of NHL and CLL were infusion-related reactions, neutropenia, leukopenia, anemia, thrombocytopenia, and infections. Additionally, lymphopenia and lung disorder were seen in NHL trials; and febrile neutropenia, pancytopenia, hypotension, and hepatitis B were seen in CLL trials
The most common adverse reactions (incidence ≥25%) in clinical trials of NHL and CLL were infusion-related reactions. Additionally, fever, lymphopenia, chills, infection, and asthenia were seen in NHL trials; and neutropenia was seen in CLL trials
