TREANDA is indicated for the treatment of patients with chronic lymphocytic leukemia (CLL). Efficacy relative to first-line therapies other than chlorambucil has not been established.
TREANDA is indicated for the treatment of patients with indolent B-cell non-Hodgkin lymphoma (NHL) that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen.
Contraindication: TREANDA is contraindicated in patients with a known hypersensitivity (e.g., anaphylactic and anaphylactoid reactions) to bendamustine.
Myelosuppression: TREANDA caused severe myelosuppression (Grade 3-4) in 98% of patients in the two NHL studies. Three patients (2%) died from myelosuppression-related adverse reactions. Monitor leukocytes, platelets, hemoglobin (Hgb), and neutrophils frequently. Myelosuppression may require dose delays and/or subsequent dose reductions if recovery to the recommended values has not occurred by the first day of the next scheduled cycle.
Infections: Infection, including pneumonia, sepsis, septic shock, hepatitis and death have occurred. Patients with myelosuppression following treatment with TREANDA are more susceptible to infections. Patients treated with TREANDA are at risk for reactivation of infections including (but not limited to) hepatitis B, cytomegalovirus, Mycobacterium tuberculosis, and herpes zoster. Patients should undergo appropriate measures (including clinical and laboratory monitoring, prophylaxis, and treatment) for infection and infection reactivation prior to administration.
Anaphylaxis and Infusion Reactions: Infusion reactions to TREANDA have occurred commonly in clinical trials. Symptoms include fever, chills, pruritus, and rash. In rare instances severe anaphylactic and anaphylactoid reactions have occurred, particularly in the second and subsequent cycles of therapy. Monitor clinically and discontinue drug for severe (Grade 3-4) reactions. Ask patients about symptoms suggestive of infusion reactions after their first cycle of therapy. Consider measures to prevent severe reactions, including antihistamines, antipyretics, and corticosteroids in subsequent cycles in patients who have experienced Grade 1 or 2 infusion reactions.
Tumor Lysis Syndrome: Tumor lysis syndrome associated with TREANDA treatment has occurred. The onset tends to be within the first treatment cycle of TREANDA and, without intervention, may lead to acute renal failure and death. Preventive measures include vigorous hydration and close monitoring of blood chemistry, particularly potassium and uric acid levels. There may be an increased risk of severe skin toxicity when TREANDA and allopurinol are administered concomitantly.
Skin Reactions: Fatal and serious skin reactions have been reported with TREANDA treatment and include, toxic skin reactions, [Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS)], bullous exanthema and rash. Events occurred when TREANDA was given as a single agent and in combination with other anticancer agents or allopurinol. Where skin reactions occur, they may be progressive and increase in severity with further treatment. Monitor patients with skin reactions closely. If skin reactions are severe or progressive, withhold or discontinue TREANDA.
Hepatotoxicity: Fatal and serious cases of liver injury have been reported with TREANDA. Combination therapy, progressive disease or reactivation of hepatitis B were confounding factors in some patients. Most cases were reported within the first three months of starting therapy. Monitor liver chemistry tests prior to and during bendamustine therapy.
Other Malignancies: There are reports of pre-malignant and malignant diseases that have developed in patients who have been treated with TREANDA, including myelodysplastic syndrome, myeloproliferative disorders, acute myeloid leukemia, and bronchial carcinoma. The association with bendamustine hydrochloride therapy has not been determined.
Extravasation Injury: TREANDA extravasations have been reported in postmarketing resulting in hospitalizations from erythema, marked swelling, and pain. Assure good venous access prior to starting TREANDA infusion and monitor the intravenous infusion site for redness, swelling, pain, infection, and necrosis during and after administration of TREANDA.
Embryo-Fetal Toxicity: TREANDA can cause fetal harm when administered to a pregnant woman. Conduct pregnancy testing prior to initiating treatment and advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use an effective method of contraception during treatment with TREANDA and for at least 6 months after the final dose and males with female partners of reproductive potential to use effective contraception for at least 3 months after the final dose. TREANDA may also impair fertility in males.
Lactation: Advise patients that breastfeeding is not recommended during treatment with TREANDA, and for at least 1 week after the last dose.
Most Common Adverse Reactions:
During TREANDA infusion and within 24 hours post-infusion, adverse reactions (frequency >5%) are nausea and fatigue.
The most common adverse reactions for CLL (frequency ≥15%) are anemia, thrombocytopenia, neutropenia, lymphopenia, leukopenia, pyrexia, nausea, and vomiting.
The most common adverse reactions for NHL (frequency ≥15%) are lymphopenia, leukopenia, anemia, neutropenia, thrombocytopenia, nausea, fatigue, vomiting, diarrhea, pyrexia, constipation, anorexia, cough, headache, weight decreased, dyspnea, rash, and stomatitis.
