In first-line follicular lymphoma patients who responded to R-CHEMO
RITUXAN maintenance therapy reduced the risk of progression, relapse, or death by 46% and extended time in remission1
- *In a Kaplan-Meier PFS curve, when the patient population gets smaller, either due to availability for analysis or progression, a single event can result in a drastic drop in the curve. PFS assessment after 27 months is based on <10% of the patient population and the plot cannot be used to reliably predict PFS beyond this time point.
- The risk of progression, relapse, or death nearly doubled (1.85x) for patients in the observation arm (P<0.0001)†
- †The risk of progression, relapse, or death for the observation arm of the PRIMA trial was calculated using the formula 1/HR.
RITUXAN maintenance following a response to first-line R-CHEMO showed higher response rates at 2 years vs observation2,3
RESPONSE RATES IN THE RANDOMIZED POPULATION BASED ON INVESTIGATOR ANALYSIS2,3‡
- ‡Patients who did not respond to induction were not randomized to the maintenance or observation stage in PRIMA.
- §N values do not include the patients (n=231) still undergoing RITUXAN maintenance or observation at the time of the interim analysis.2
- Two-year response rates were a prespecified secondary endpoint in the PRIMA trial3
SELECT IMPORTANT SAFETY INFORMATION
Single-agent RITUXAN as maintenance for follicular NHL after first-line RITUXAN-based chemotherapy
- Detailed safety data collection was limited to Grade ≥2 infections, Grade ≥3 adverse reactions, and serious adverse reactions
- The most common Grade 3-4 adverse reactions occurring at a higher incidence (≥2%) in the RITUXAN arm than in the observation arm were infections (4% vs. 1%) and neutropenia (4% vs. <1%)
- The most frequently reported adverse reaction was infections. In patients receiving RITUXAN as single-agent maintenance therapy following RITUXAN plus chemotherapy, infections were reported more frequently compared with the observation arm (37% vs. 22%)
R-CHEMO=RITUXAN plus chemotherapy; HR=hazard ratio; CI=confidence interval; PFS=progression-free survival; IRC=Independent Review Committee; PRIMA=Primary RItuximab and MAintenance; CR=complete response; CRu=complete response, unconfirmed; PR=partial response; ORR=overall response rate.

RITUXAN® (Rituximab) is indicated for the treatment of 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 RITUXAN 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
- Previously untreated and previously treated CD20-positive CLL in combination with fludarabine and cyclophosphamide (FC)
RITUXAN is not recommended for use in patients with severe, active infections.
Important Safety Information
WARNING: FATAL INFUSION REACTIONS, SEVERE MUCOCUTANEOUS REACTIONS, HEPATITIS B VIRUS REACTIVATION and PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY
- Infusion Reactions: RITUXAN administration can result in serious, including fatal infusion 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 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
Warnings and Precautions
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. A high number of circulating malignant cells (≥25,000/mm3) or high tumor burden, confers a greater risk of TLS. Administer aggressive intravenous hydration and anti hyperuricemic therapy in patients at high risk for TLS
- Serious, including fatal, bacterial, fungal, and new or reactivated viral infections can occur during and following the completion of RITUXAN-based therapy. Discontinue RITUXAN for serious infections and institute appropriate anti infective therapy
- Discontinue infusions for serious or life threatening cardiac arrhythmias. Perform cardiac monitoring during and after all infusions of RITUXAN for patients who develop clinically significant arrhythmias, or who have a history of arrhythmia or angina
- Severe, including fatal, renal toxicity can occur after RITUXAN administration in patients with NHL. Monitor closely for signs of renal failure and discontinue RITUXAN in patients with a 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. Evaluate if symptoms of obstruction such as abdominal pain or repeated vomiting occur
- The safety of immunization with live viral vaccines following RITUXAN therapy has not been studied and vaccination with live virus vaccines is not recommended
- Obtain complete blood counts (CBC) prior to each RITUXAN course
Additional Important Safety Information
- The most common Grade 3 or 4 adverse reactions in clinical trials of NHL and CLL were infusion 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 reactions. Additionally, fever, lymphopenia, chills, infection, and asthenia were seen in NHL trials; and neutropenia was seen in CLL trials
- Pregnancy: Category C. There are no adequate and well-controlled studies of rituximab in pregnant women
