Before starting Bendeka, it is important to speak to your doctor or pharmacist about your medication and medical history. Inform your doctor or pharmacist of:

  • Any allergic reaction to Bendeka or to any of its components 
  • Your complete allergy history and the type of reaction that you experienced
  • Liver problems, heart disease, kidney disease, and any recent or current infections
  • Pregnancy or breastfeeding

Bendeka has been FDA-approved for the following labeled indications: 

  • Chronic lymphocytic leukemia (CLL)
  • Non-Hodgkin lymphoma (NHL), indolent (refractory)

There are also off-label indications in which Bendeka can be prescribed. These indications include: 

  • Hodgkin lymphoma (relapsed or refractory)
  • Multiple myeloma (salvage therapy)
  • Non-Hodgkin lymphoma, diffuse large B-cell (relapsed or refractory)
  • Non-Hodgkin lymphoma, indolent and mantle cell, first-line treatment
  • Non-Hodgkin lymphoma, mantle cell (relapsed or refractory)
  • Waldentrom macroglobulinemia

What Is Bendeka Used For? 

As mentioned above, Bendeka is used for treating a variety of lymphomas and myeloma.

  • Lymphomas are characterized as a type of cancer or abnormal growth of the lymphatic system (the body’s germ-fighting network). 
  • Myeloma is a type of cancer that affects the bone marrow (the blood-producing tissue located in the center of most bones in our body). 

Bendeka works by killing cancer cells or slowing the cancer growth in the bone marrow or lymphatic system.

How Does It Work? (Mechanism of Action)

Bendeka belongs to the chemotherapy drug class called alkylating agents (nitrogen mustard derivative). Alkylating agents directly act on the DNA of cancer cells, resulting in crosslinking and DNA strand breaks. This leads to abnormal base pairing and inhibition of cell division, eventually causing cancer cell death.
