About FUSILEV® (levoleucovorin) for injection
FUSILEV, a novel folate analog, is approved as a ready-to-use solution
(FUSILEV® Injection), and as freeze-dried powder (FUSILEV for
Injection). FUSILEV is indicated for use in combination chemotherapy
with 5-fluorouracil in the palliative treatment of patients with
advanced metastatic colorectal cancer. FUSILEV is also indicated for
rescue after high-dose methotrexate therapy in osteosarcoma. FUSILEV is
also indicated to diminish the toxicity and counteract the effects of
impaired methotrexate elimination and of inadvertent overdosage of folic
acid antagonists. FUSILEV, under various trade names, is marketed
Important FUSILEV® (levoleucovorin) Safety Considerations
FUSILEV is dosed at one-half the usual dose of racemic d,l-leucovorin. FUSILEV is contraindicated for patients who have had previous allergic reactions attributed to folic acid or folinic acid. Due to calcium content, no more than 16-mL (160-mg) of levoleucovorin solution should be injected intravenously per minute. FUSILEV enhances the toxicity of fluorouracil. Concomitant use of d,l-leucovorin with trimethoprim-sulfamethoxazole for pneumocystis carinii pneumonia in HIV patients was associated with increased rates of treatment failure in a placebo-controlled study. Allergic reactions were reported in patients receiving FUSILEV. Vomiting (38%), stomatitis (38%) and nausea (19%) were reported in patients receiving FUSILEV as rescue after high dose methotrexate therapy. The most common adverse reactions ( > 50%) in patients with advanced colorectal cancer receiving FUSILEV in combination with 5-fluorouracil were diarrhea, nausea and stomatitis. FUSILEV may counteract the antiepileptic effect of phenobarbital, phenytoin and primidone, and increase the frequency of seizures in susceptible patients.

Important FOLOTYN® Safety Information
Warnings and Precautions
FOLOTYN may suppress bone marrow function, manifested by thrombocytopenia, neutropenia, and anemia. Monitor blood counts and omit or modify dose for hematologic toxicities.
Mucositis may occur. If greater-than or equal to Grade 2 mucositis is observed, omit or modify dose. Patients should be instructed to take folic acid and receive vitamin B12 to potentially reduce treatment-related hematological toxicity and mucositis.
Fatal dermatologic reactions may occur. Dermatologic reactions may be progressive and increase in severity with further treatment. Patients with dermatologic reactions should be monitored closely, and if severe, FOLOTYN should be withheld or discontinued. Tumor lysis syndrome may occur. Monitor patients and treat if needed.
FOLOTYN can cause fetal harm. Women should avoid becoming pregnant while being treated with FOLOTYN and pregnant women should be informed of the potential harm to the fetus.
Use caution and monitor patients when administering FOLOTYN to patients with moderate to severe renal function impairment.
Elevated liver function test abnormalities may occur and require monitoring. If liver function test abnormalities are greater-than or equal to Grade 3, omit or modify dose.
The most common adverse reactions were mucositis (70%), thrombocytopenia (41%), nausea (40%), and fatigue (36%). The most common serious adverse events are pyrexia, mucositis, sepsis, febrile neutropenia, dehydration, dyspnea, and thrombocytopenia.
Use in Specific Patient Population
Nursing mothers should be advised to discontinue nursing or the drug, taking into consideration the importance of the drug to the mother.
Co-administration of drugs subject to renal clearance (e.g., probenecid, NSAIDs, and trimethoprim/sulfamethoxazole) may result in delayed renal clearance.

Important ZEVALIN® Safety Information
Deaths have occurred within 24 hours of rituximab infusion, an essential component of the ZEVALIN therapeutic regimen. These fatalities were associated with hypoxia, pulmonary infiltrates, acute respiratory distress syndrome, myocardial infarction, ventricular fibrillation, or cardiogenic shock. Most (80%) fatalities occurred with the first rituximab infusion. ZEVALIN administration can result in severe and prolonged cytopenias in most patients. Severe cutaneous and mucocutaneous reactions, some fatal, can occur with the ZEVALIN therapeutic regimen.
