TREANDA® is a unique treatment that combines an alkylating group with a purine-like benzimidazole ring.1,2

  • The alkylating group contains mechlorethamine, which confers alkylating properties
  • The benzimidazole component contains a purine antagonist (a benzimidazole ring)3,4
  • The exact mechanism of action of TREANDA remains unknown

TREANDA for injection is indicated for the treatment of patients with indolent B-cell non-Hodgkin’s lymphoma that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen. TREANDA is also indicated for the treatment of patients with chronic lymphocytic leukemia (CLL). Efficacy relative to first-line therapies other than chlorambucil has not been established.

The following serious adverse reactions have been associated with TREANDA: myelosuppression, infections, infusion reactions and anaphylaxis, tumor lysis syndrome, skin reactions including SJS/TEN, other malignancies, and extravasation. Some of these reactions have been fatal, including myelosuppression, infections, and SJS/TEN (when TREANDA was administered concomitantly with allopurinol and other medications known to cause SJS/TEN). Patients should be monitored closely for these reactions and treated promptly if any occur. Adverse reactions may require interventions such as decreasing the dose of TREANDA, or withholding or delaying treatment. Myelosuppression is frequently severe and should be expected when treating patients with TREANDA.

TREANDA is contraindicated in patients with a known hypersensitivity to bendamustine or mannitol. Women should be advised to avoid becoming pregnant while using TREANDA.

The most common non-hematologic adverse reactions associated with TREANDA (frequency ≥15%) are nausea, fatigue, vomiting, diarrhea, pyrexia, constipation, anorexia, cough, headache, weight decreased, dyspnea, rash, and stomatitis. The most common hematologic abnormalities associated with TREANDA (frequency ≥15%) are lymphopenia, anemia, leukopenia, thrombocytopenia, and neutropenia.
