What Adcetris is used for

Adcetris contains the active ingredient brentuximab vedotin.

Adcetris belongs to a group of medicines known as anti-cancer agents. There are many different classes of anti-cancer agents.

Adcetris is designed to work differently than traditional anti-cancer agents (chemotherapy). Traditional chemotherapy enters the blood and kills both cancer cells and healthy cells that divide rapidly. Adcetris is made up of a monoclonal antibody linked to a substance intended to kill cancer cells. This substance is delivered to cancer cells by the monoclonal antibody.

A monoclonal antibody is a protein which recognises certain cancer cells.

Adcetris is used to treat Hodgkin Lymphoma that has come back or not responded to previous treatment.

Adcetris may also be used alone to lower the likelihood of Hodgkin Lymphoma coming back after a stem cell transplant in patients with certain risk factors. In these patients, Adcetris may help prevent or delay recurrence of disease. Your doctor will discuss the potential risks and benefits of receiving Adcetris following a stem cell transplant.

Hodgkin Lymphoma is a type of cancer of the white blood cells.

Adcetris is also used to treat patients with cutaneous T-Cell Lymphoma (CTCL) who have previously received at least one anti-cancer medicine that travels through the bloodstream.

CTCL is a cancer of a certain type of white blood cell called a ‘T-cell’ that mainly affects the skin. Adcetris is used to treat CTCL where a specific type of protein is present on the cells’ surface.

Adcetris is also used to treat patients with peripheral T-Cell Lymphoma (PTCL) who have not had treatment before.

PTCL is a type of non Hodgkin Lymphoma found in the lymph nodes and/or throughout other parts of the body. When Adcetris is used to treat PTCL that has not already been treated, it is given in combination with other chemotherapy medicines used to treat this condition.

Systemic Anaplastic Large Cell Lymphoma (sALCL) is a type of PTCL. Adcetris may also be used alone to treat sALCL that has come back or not responded to previous treatment.

Ask your doctor if you have any questions about why it has been prescribed for you.

Your doctor may have prescribed it for another purpose.

This medicine is available only with a doctor's prescription.

How Adcetris is given

Adcetris is given by an infusion into a vein (intravenous infusion) over 30 minutes by a healthcare professional. You will be monitored during and after the infusion.

Your doctor will decide what dose and how long you will receive Adcetris .

The dose of Adcetris depends on your body weight.

The usual recommended dose of Adcetris when it is given alone is 1.8 mg/kg, given once every 3 weeks. Your doctor may lower your starting dose if you have kidney or liver problems.

If you are a patient with PTCL that has not already been treated, you will receive Adcetris in combination with cyclophosphamide, doxorubicin, and prednisone which are other medicines used to treat this condition. See the Consumer Medicine Information leaflets for these medicines given in combination with Adcetris for additional information on their use and effects.

The usual dose of Adcetris given in combination with cyclophosphamide, doxorubicin, and prednisone is 1.8 mg/kg given every 3 weeks for approximately 4 - 6 months. Your doctor may lower your starting dose if you have mild liver problems.

Adcetris is to be given to adults only. It is not for use in children.

Overdose

As Adcetris is given to you under the supervision of your doctor, it is very unlikely that you will receive too much. However, if you experience any side effects after being given Adcetris, tell your doctor immediately.
