Chemotherapy used to be the main treatment for this disease. Now, most people do very well with targeted therapies and immunotherapies. As result, chemotherapy has little to no role.
Targeted therapies work in one of three ways:
- They target a gene or protein that causes cancer growth.
- They damage cancer cells directly.
- They tell your immune system to attack certain cells. This is also called immunotherapy.
Your hematologist-oncologist will prescribe your targeted therapy and set your treatment schedule. Targeted therapies are usually given as a pill that you take at home. Some are given by infusion in repeating cycles. Liquid medicine is put into a vein through an intravenous (IV) line. This can be a line in your arm (peripheral venous catheter) or a port in your chest (central venous catheter).
You get infusions in a dedicated area of the clinic. Cancer nurses who are experts in infusions will give you these treatments. They will also monitor you during the treatment. They respond to any medical issues that come up and help keep you comfortable.
We have several options that target different features of CLL. Some are used as first-line treatments. Some are saved and used after trying other treatments first. They can be used alone or with other medicines.
Options for targeted therapy
Examples of targeted CLL therapies include:
- Ibrutinib, acalabrutinib and zanubrutinib. They block the enzyme called Bruton’s tyrosine kinase.
- Venetoclax. It targets CLL with the BCL-2 protein.
- Idelalisib and duvelisib. They block the protein PI3K.
Some medicines can be thought of as both immunotherapies and targeted therapies — like rituximab, ofatumumab and obinutuzumab. They target the CD20 protein.
More targeted therapies are being tested and are available through clinical trials.
Chemotherapy
Treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It may be given alone or with other treatments.
Treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Chemotherapy may be given by mouth, injection, infusion or on the skin, depending on the type and stage of the cancer being treated. It may be given alone or with other treatments, such as surgery, radiation therapy or biologic therapy.
Gene
The functional and physical unit of heredity passed from parent to offspring. Genes are pieces of DNA, and most genes contain the information for making a specific protein.
Hematologist
A physician who specializes in diseases of the blood and blood-forming tissues.
Immunotherapy
A type of therapy that uses substances to stimulate or suppress the immune system to help the body fight cancer, infection and other diseases.
A therapy that uses substances to stimulate or suppress the immune system to help the body fight cancer, infection and other diseases. Some immunotherapies only target certain cells of the immune system. Others affect the immune system in a general way. Types of immunotherapy include cytokines, vaccines, bacillus Calmette-Guerin (BCG) and some monoclonal antibodies.

Infusion
An injection of medications or fluids into a vein over a period of time.

Targeted therapy
A type of treatment that uses drugs or other substances to identify and attack specific types of cancer cells while causing less harm to normal cells.
A type of treatment that uses drugs or other substances to identify and attack specific types of cancer cells while causing less harm to normal cells. Some targeted therapies block the action of certain enzymes, proteins or other molecules involved in the growth and spread of cancer cells. Other types of targeted therapies help the immune system kill cancer cells, or they deliver toxic substances directly to cancer cells and kill them. Targeted therapy may have fewer side effects than other types of cancer treatment. Most targeted therapies are either small molecule drugs or monoclonal antibodies.
