How do I apply for the Kadcyla patient assistance program?

Applying for the Kadcyla patient assistance program through NiceRx is simple. Begin by completing the enrollment application on our website. We will ask for details about your healthcare provider, your insurance plan, and your household income. This information is required by the pharmaceutical manufacturers that supply your medication.

What is Kadcyla?

Kadcyla contains the prescription medicine ado-trastuzumab emtansine. Kadcyla is used for the treatment of HER2-positive breast cancer. It is used for early breast cancer and metastatic breast cancer (where the breast cancer has spread to other parts of the body). Kadcyla is used where another medication has failed or where cancer has come back.

Kadcyla is given as an infusion directly into a vein. The process can take 30 to 90 minutes to complete. Kadcyla is given once every 3 weeks and you will need to be monitored closely to make sure the medicine is not causing any harmful side effects.

Kadcyla active ingredients

Ado-trastuzumab emtansine is a HER2-targeted antibody-drug conjugate, meaning that the medication acts directly on the cancer cells.

The antibody is the humanized anti-HER2 IgG1, trastuzumab. Humanized antibodies are antibodies from non-human species that have been modified to make them more similar to antibodies produced naturally in humans. The small molecule cytotoxin, DM1, is a microtubule inhibitor. Its function is to block the function of cellular microtubules. Microtubules are made from tubulin and are key to the structure of cells. Microtubules are involved in transport, cell shape, movement, and cell division. Through a series of biological processes involving ado-trastuzumab emtansine, DM1 is released into the cells. DM1 attaches itself to tubulin, blocking the entire microtubule network in the cell and eventually leading to cell death.
