for Cancer Treatment
Targeted therapies are designed to attack or kill cancer cells, while sparing normal cells as much as possible. These therapies are often designed to attach to abnormal proteins, receptors or genes that are found in high quantities in cancer cells or the surrounding tissue.
This section covers the following topics.
How are targeted therapies selected?
Some, but not all targeted therapies work best against cancer cells with certain markers or mutations. Two important types of tests can help guide selection of these targeted therapies.
- testing involves looking at tumor, blood or other other tissue samples for abnormal markers that might indicate the cancer is likely to respond to a particular . You can learn more about testing for selecting targeted therapies in our Biomarkers sections.
- Genetic testing for inherited mutations can also help guide treatment with targeted therapies. PARP inhibitors, for example, are a type of that are most effective for treating cancer in people with a or mutation.
Each drug has different indications. Like all cancer treatments, targeted therapies can have side effects. Visit our section on Side Effects for more information.
PARP inhibitors
PARP inhibitors work by blocking a protein used to repair damaged . They were initially developed to treat cancers in people with an inherited or mutation. Since then, research and additional approvals have expanded use of PARP inhibitors to more people and situations. There are five PARP inhibitors that have received approval for treating different types of cancers.
Indications vary by:
- type and of cancer: PARP inhibitors have been approved to treat breast, ovarian, pancreatic and cancers.
- presence of a mutation or biomarker: PARP inhibitors have been approved in different settings for:
- people with certain inherited mutations.
- people with certain acquired mutations.
- people with certain tumor biomarkers.
- women with certain types of ovarian cancer, regardless of the presence of an or .
- number of and response to prior treatments: have been approved in different settings for:
- platinum-sensitive or partially platinum-sensitive ovarian cancer.
- castration-resistent cancer (mCRPC).
- after chemotherapy.
- to treat progression or recurrence after a specific number of prior treatments.
Clinical trials studying PARP inhibitors in new settings or combinations are enrolling patients. As research continues, these approvals may expand to include treatment for additional cancers, earlier stages of cancer, people with other inherited mutations, and based on different tumor biomarkers.

Other targeted therapies
There is a growing list of FDA-approved targeted therapies for cancer treatment. Most are classified by the abnormal target that they are designed to bind to and attack. Many of these new therapies are approved for use in all types of cancers () as long as the cancer contains the right marker or target. Drugs that are approved across cancer types are sometimes called pan-tumor or tumor-agnostic therapies.
Some drugs are classified as both immunotherapies and targeted therapies because they use antibodies to target abnormal proteins or receptors that are found in high quantities in cancer cells or the surrounding tissue. Antibody drug conjugates (ADCs) are drugs that combine two different types of molecules. A chemotherapy drug is linked to an antibody that delivers the chemotherapy directly to the cancer cells.
The table below lists some common targeted therapies used in cancer treatment. Clincal trials are studying new agents for treating cancer.
