( 5.8 , 8.1 , 8.3 )
5.1Serious Infusion Reactions Rituximab, alone or as a component of the Zevalin therapeutic regimen, can cause severe, including fatal, infusion reactions. These reactions typically occur during the first rituximab infusion with time to onset of 30 to 120 minutes. Signs and symptoms of severe infusion reactions may include urticaria, hypotension, angioedema, hypoxia, bronchospasm, pulmonary infiltrates, acute respiratory distress syndrome, myocardial infarction, ventricular fibrillation, and cardiogenic shock.
Temporarily slow or interrupt the rituximab infusion for less severe infusion reactions. Immediately discontinue rituximab and Y-90 Zevalin administration for severe infusion reactions. Only administer rituximab/Zevalin in facilities where immediate access to resuscitative measures is available [ see Boxed Warning and Dosage and Administration ( 2.2 ) ].
See also prescribing information for rituximab.
5.2Prolonged and Severe Cytopenias Cytopenias with delayed onset and prolonged duration, some complicated by hemorrhage and severe infection, are the most common severe adverse reactions of the Zevalin therapeutic regimen. When used according to recommended doses, the incidences of severe thrombocytopenia and neutropenia are greater in patients with mild baseline thrombocytopenia (≥ 100,000 but ≤ 149,000/mm 3 ) compared to those with normal pretreatment platelet counts. Severe cytopenias persisting more than 12 weeks following administration can occur.
Monitor complete blood counts (CBC) and platelet counts following the Zevalin therapeutic regimen weekly until levels recover or as clinically indicated [ see Boxed Warning and Adverse Reactions ( 6.1 ) ]. Do not administer the Zevalin therapeutic regimen to patients with ≥ 25% lymphoma marrow involvement and/or impaired bone marrow reserve. Monitor patients for cytopenias and their complications (e.g., febrile neutropenia, hemorrhage) for up to 3 months after use of the Zevalin therapeutic regimen.
Avoid using drugs which interfere with platelet function or coagulation following the Zevalin therapeutic regimen.
5.3Severe Cutaneous and Mucocutaneous Reactions Erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, bullous dermatitis, and exfoliative dermatitis, some fatal, were reported in post-marketing experience. The time to onset of these reactions was variable, ranging from a few days to 4 months after administration of the Zevalin therapeutic regimen. Discontinue the Zevalin therapeutic regimen in patients experiencing a severe cutaneous or mucocutaneous reaction [ see Boxed Warning and Adverse Reactions ( 6.2 ) ].
5.4Risk of Developing Myelodysplastic Syndrome, Leukemia, and Other Malignancies The radiation dose resulting from therapeutic exposure to Y-90 radiolabeled Zevalin may result in secondary malignancies. Myelodysplastic syndrome (MDS) and/or acute myelogenous leukemia (AML) were reported in 5.2% (11/211) of patients with relapsed or refractory NHL enrolled in clinical studies and 1.5% (8/5… [Excerpted — this section continues on DailyMed.]

6.1Clinical 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 practice. The reported safety data reflects exposure to Zevalin in 349 patients with relapsed or refractory, low-grade, follicular or transformed NHL across 5 trials (4 single arm and 1 randomized) and in 206 patients with previously untreated follicular NHL in a randomized trial (FIT study) who received any portion of the Zevalin therapeutic regimen.
The safety data reflect exposure to Zevalin in 270 patients with relapsed or refractory NHL with platelet counts ≥150,000/ mm 3 who received 0.4 mCi/kg (14.8 MBq/kg) of Y-90 Zevalin (Group 1 in Table 4 ), 65 patients with relapsed or refractory NHL with platelet counts of ≥ 100,000 but ≤ 149,000 /mm 3 who received 0.3 mCi/kg (11.1 MBq/kg) of Y-90 Zevalin (Group 2 in Table 4 ), and 204 patients with previously untreated NHL with platelet counts ≥150,000/ mm 3 who received 0.4 mCi/kg (14.8 MBq/kg) of Y-90 Zevalin; all patients received a single course of Zevalin.
The most common adverse reactions of Zevalin are cytopenias, fatigue, nasopharyngitis, nausea, abdominal pain, asthenia, cough, diarrhea, and pyrexia. The most serious adverse reactions of Zevalin are prolonged and severe cytopenias (thrombocytopenia, anemia, lymphopenia, neutropenia) and secondary malignancies. Because the Zevalin therapeutic regimen includes the use of rituximab, see prescribing information for rituximab.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Advise women not to breastfeed. ( 8.2 )
8.1Pregnancy Risk Summary Based on its radioactivity, Y-90 Zevalin may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 )] . Immunoglobulins are known to cross the placenta. There are no available data on Zevalin use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage.
Advise women of childbearing potential to use adequate contraception for a minimum of twelve months. Inform women who become pregnant while receiving Zevalin of the potential fetal risks. The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. However, the background risk in the U.S. general population of major birth defects is 2-4% and of miscarriage is 15-20% of clinically recognized pregnancies.
8.2Lactation Risk Summary There are no data on the presence of Zevalin or its metabolites in human milk, the effects of Zevalin on the breastfed child, or its effects on milk production. Because human IgG is excreted in human milk, it is expected that Zevalin would be present in human milk. Due to the potential for serious adverse reactions in a breastfeeding child from Zevalin, advise lactating women to avoid breastfeeding during treatment with the Zevalin therapeutic regimen and for 6 months after the last dose.
8.3Females and Males of Reproductive Potential Zevalin may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Conduct pregnancy testing in females of reproductive potential prior to treatment with Zevalin. Contraception Females Based on its radioactivity, Y-90 Zevalin may cause fetal harm.
Advise females of reproductive potential to use effective contraceptive methods during treatment and for 12 months after the last dose of the Zevalin therapeutic regimen [see Clinical Pharmacology ( 12.1 )] . Males Based on its radioactivity, Y-90 Zevalin may cause fetal harm. Advise males with female partners of reproductive potential to use effective contraceptive methods during treatment and for 12 months after the final dose of the Zevalin therapeutic regimen [see Clinical Pharmacology ( 12.1 )].
Infertility Based on its radioactivity, there is a potential risk that the Zevalin therapeutic regimen could cause toxic effects on the male and female gonads [see Clinical Pharmacology ( 12.1 ) and Nonclinical Toxicology ( 13.1 )] .
8.4Pediatric Use The safety and effectiveness of Zevalin have not been established in pediatric patients.
8.5Geriatric Use Of 349 patients with relapsed/refractory NHL treated with the Zevalin therapeutic regimen in clinical studies, 38% (132 patients) were age 65 years and over, while 12% (41 patients) were age 75 years and over. Of 414 patients enrolled in the FIT study (Zevalin following first-line chemotherapy) 206 patients received Zevalin. Of these patients 14% (29 patients) were 65 years and over, while 2% (4 patients) were 75 years and older.
No overall differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Ibritumomab tiuxetan binds specifically to the CD20 antigen (human B-lymphocyte-restricted differentiation antigen, Bp35). The apparent affinity (K D ) of ibritumomab tiuxetan for the CD20 antigen ranges between approximately 14 to 18 nM. The CD20 antigen is expressed on pre-B and mature B lymphocytes and on > 90% of B-cell non-Hodgkin’s lymphomas (NHL).
The CD20 antigen is not shed from the cell surface and does not internalize upon antibody binding. The chelate tiuxetan, which tightly binds Y-90, is covalently linked to ibritumomab. The beta emission from Y-90 induces cellular damage by the formation of free radicals in the target and neighboring cells.
Ibritumomab tiuxetan binding was observed in vitro on lymphoid cells of the bone marrow, lymph node, thymus, red and white pulp of the spleen, and lymphoid follicles of the tonsil, as well as lymphoid nodules of other organs such as the large and small intestines.
12.2Pharmacodynamics In clinical studies, administration of the Zevalin therapeutic regimen resulted in sustained depletion of circulating B cells. At four weeks, the median number of circulating B cells was zero (range, 0-1084/mm 3 ). B-cell recovery began at approximately 12 weeks following treatment, and the median level of B cells was within the normal range (32 to 341/mm 3 ) by 9 months after treatment.
Median serum levels of IgG and IgA remained within the normal range throughout the period of B-cell depletion. Median IgM serum levels dropped below normal (median 49 mg/dL, range 13-3990 mg/dL) after treatment and recovered to normal values by 6-months post therapy.
12.3Pharmacokinetics Pharmacokinetic and biodistribution studies were performed using In-111 Zevalin (5 mCi [185 MBq] In-111, 1.6 mg ibritumomab tiuxetan). In an early study designed to assess the need for pre-administration of unlabeled antibody, only 18% of known sites of disease were imaged when In-111 Zevalin was administered without unlabeled ibritumomab. When preceded by unlabeled ibritumomab (1.0 mg/kg or 2.5 mg/kg), In-111 Zevalin detected 56% and 92% of known disease sites, respectively.
These studies were conducted with a Zevalin therapeutic regimen that included unlabeled ibritumomab. In pharmacokinetic studies of patients receiving the Zevalin therapeutic regimen, the mean effective half-life for Y-90 activity in blood was 30 hours, and the mean area under the fraction of injected activity (FIA) vs. time curve in blood was 39 hours. Over 7 days, a median of 7.2% of the injected activity was excreted in urine.

📋 Description ▾
11 DESCRIPTION Zevalin (ibritumomab tiuxetan) is the immunoconjugate resulting from a stable thiourea covalent bond between the monoclonal antibody ibritumomab and the linker-chelator tiuxetan [N-[2-bis(carboxymethyl) amino]-3-(p-isothiocyanatophenyl)-propyl]-[N-[2-bis(carboxymethyl)amino]-2- (methyl)-ethyl]glycine. This linker-chelator provides a high affinity, conformationally restricted chelation site for Yttrium-90. The approximate molecular weight of ibritumomab tiuxetan is 148 kD.
The antibody moiety of Zevalin is ibritumomab, a murine IgG 1 kappa monoclonal antibody directed against the CD20 antigen. Ibritumomab tiuxetan is a clear, colorless, sterile, pyrogen-free, preservative-free solution that may contain translucent particles. Each single-use vial includes 3.2 mg of ibritumomab tiuxetan in 2 mL of 0.9% Sodium Chloride.
Physical/Radiochemical Characteristics of Y-90 Yttrium-90 decays by emission of beta particles, with a physical half-life of 64.1 hours (2.67 days). The product of radioactive decay is non-radioactive Zirconium-90. The range of beta particles in soft tissue ( χ 90) is 5 mm.
Radiation emission data for Y-90 are summarized in Table 5 . Table 5. Principal Y-90 Radiation Emission Data Radiation Mean % per Disintegration Mean Energy (keV) Beta minus 100 750-935 External Radiation The exposure rate for 1 mCi (37 MBq) of Y-90 is 8.3 x 10 -3 C/kg/hr (32 R/hr) at the mouth of an open Y-90 vial.

🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Pharmacokinetic and biodistribution studies were performed using In-111 Zevalin (5 mCi [185 MBq] In-111, 1.6 mg ibritumomab tiuxetan). In an early study designed to assess the need for pre-administration of unlabeled antibody, only 18% of known sites of disease were imaged when In-111 Zevalin was administered without unlabeled ibritumomab. When preceded by unlabeled ibritumomab (1.0 mg/kg or 2.5 mg/kg), In-111 Zevalin detected 56% and 92% of known disease sites, respectively.
These studies were conducted with a Zevalin therapeutic regimen that included unlabeled ibritumomab. In pharmacokinetic studies of patients receiving the Zevalin therapeutic regimen, the mean effective half-life for Y-90 activity in blood was 30 hours, and the mean area under the fraction of injected activity (FIA) vs. time curve in blood was 39 hours. Over 7 days, a median of 7.2% of the injected activity was excreted in urine.
🧬 Pharmacodynamics ▾
12.2Pharmacodynamics In clinical studies, administration of the Zevalin therapeutic regimen resulted in sustained depletion of circulating B cells. At four weeks, the median number of circulating B cells was zero (range, 0-1084/mm 3 ). B-cell recovery began at approximately 12 weeks following treatment, and the median level of B cells was within the normal range (32 to 341/mm 3 ) by 9 months after treatment.
Median serum levels of IgG and IgA remained within the normal range throughout the period of B-cell depletion. Median IgM serum levels dropped below normal (median 49 mg/dL, range 13-3990 mg/dL) after treatment and recovered to normal values by 6-months post therapy.
🔬 Clinical Studies ▾
14 CLINICAL STUDIES
14.1Relapsed or Refractory, Low-grade or Follicular Lymphoma A study to evaluate the efficacy and safety of Zevalin (referred to as Study 106-06) was a single arm study of 54 patients with relapsed follicular lymphoma, who were refractory to rituximab treatment. Patients had a World Health Organization (WHO) Performance Status (PS) 0-2, <25% bone marrow involvement by NHL, no prior bone marrow transplantation, and acceptable hematologic, renal, and hepatic function. Refractoriness to rituximab was defined as failure to achieve a complete or partial response or time-to-disease-progression (TTP) of < 6 months.
The main efficacy outcome measure of the study was the overall response rate (ORR) using the International Workshop Response Criteria (IWRC). Other efficacy outcome measures included time-to-disease-progression (TTP) and duration of response (DR). Table 7 summarizes efficacy data from Study 106-06.
Another study to evaluate the efficacy and safety of Zevalin (referred to as Study 106-04) was a randomized (1:1), open-label, multicenter study comparing the Zevalin therapeutic regimen with rituximab. The trial was conducted in 130 patients with relapsed or refractory low-grade or follicular non-Hodgkin's lymphoma (NHL); no patient had received prior rituximab. Patients had histologically confirmed NHL requiring therapy, a WHO PS 0-2, <25% bone marrow involvement by NHL, no prior bone marrow transplantation, and acceptable hematologic function.
Sixty-four patients received the Zevalin therapeutic regimen, and 66 patients received rituximab given as an IV infusion at 375 mg per m 2 weekly times 4 doses. The main efficacy outcome measure of the study was ORR using the IWRC. The ORR was significantly higher for patients receiving the Zevalin therapeutic regimen (83% vs.
55%, p<0.001). Time-to-disease-progression was not significantly different between study arms. Table 7 summarizes efficacy data from Study 106-04.

Patients with ≥ 25% lymphomatous marrow involvement, prior myeloablative therapy with stem cell support, prior external beam radiation to > 25% of active marrow or neutrophil count <1,500/mm 3 were ineligible for Study 106-05. All patients received Y-90 Zevalin [0.3 mCi per kg (11.1 MBq per kg)]. Objective, durable clinical responses were observed [89% ORR (95% CI: 70-97%) with a median duration of response of 11.6 months (range: 1.0-42.4+ months)].
14.2Follicular, B-Cell NHL Upon Completion of First-Line Chemotherapy The FIT (First-line Indolent Trial) study (NCT00185393) was a multi-center, randomized, open-label study conducted in patients with follicular NHL with a partial (PR) or complete response (CR/CRu) upon completion of first-line chemotherapy. Randomization was stratified by center and response to first-line therapy (CR or PR). Key eligibility criteria were <25% bone marrow involvement, no prior external beam radiation or myeloablative therapy, and recovery of platelets to normal levels.
Patients were randomized to receive Zevalin (n=208) or no further therapy (… [Excerpted — this section continues on DailyMed.]
🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity and mutogenicity studies have not been conducted. However, radiation is a potential carcinogen and mutagen. No animal studies have been performed to determine the effects of Zevalin on fertility in males or females.
In clinical studies, the Zevalin therapeutic regimen results in a significant radiation dose to the testes: the radiation dose to the ovaries has not been established [ see Dosage and Administration ( 2.5 )]. There is a potential risk that the Zevalin therapeutic regimen could cause toxic effects on the male and female gonads. Effective contraceptive methods should be used during treatment and for up to 12 months following the Zevalin therapeutic regimen.
13.2Animal Toxicology and/or Pharmacology Animal reproductive toxicology studies of the Zevalin therapeutic regimen have not been conducted. Because the Zevalin therapeutic regimen includes the use of rituximab, also see prescribing information for rituximab.
