Class: Biological Therapy
Generic Name: ado-trastuzumab emtansine
Trade Name: Kadcyla®
For which conditions is this drug approved? Kadcyla is indicated as a single agent for the treatment of patients with HER2-positive, metastatic breast cancer who previously received Herceptin® (trastuzumab) and a taxane, separately or in combination. In order to receive Kadcyla, patients should have either received prior therapy for metastatic disease or developed disease recurrence during or within six months of completing adjuvant therapy.
What is the mechanism of action? Kadcyla is part of a class of drugs called antibody-drug conjugates, which consist of an antibody attached to a toxic chemotherapy. Kadcyla combines Herceptin and a chemotherapy drug (emtansine or DM1) that interferes with cancer cell growth. Kadcyla delivers Herceptin and DM1 directly to HER2-positive cells and limits exposure of the rest of the body to chemotherapy.
How is Kadcyla typically given (administered)? Kadcyla is given as an intravenous infusion every three weeks until disease progression or unacceptable toxicity.
How are patients typically monitored? Patients receiving Kadcyla must be monitored for:
What are the common (occur in 30% or more of patients) side effects of treatment with Kadcyla?
What are the less common (occur in 10% to 29% of patients) side effects of treatment with Kadcyla?
This is not a complete list of side effects. Some patients may experience other side effects that are not listed here. Patients may wish to discuss with their physician the other less common side effects of this drug, some of which may be serious.
Some side effects may require medical attention. Other side effects do not require medical attention and may go away during treatment. Patients should check with their physician about any side effects that continue or are bothersome.
What can patients do to help alleviate or prevent discomfort and side effects? Follow your dosing schedule for Kadcyla and discuss with your healthcare providers all health conditions and concerns and medications you are taking (over the counter and prescription).
Are there any special precautions patients should be aware of before starting treatment? Kadcyla can harm an unborn baby. Women of childbearing age should use effective contraception while receiving treatment and for six months following the last dose of Kadcyla. Nursing mothers should not nurse while receiving Kadcyla. Women who are exposed to Kadcyla during pregnancy are encouraged to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720.
When should patients notify their physician?
