What Is Inlyta?
Inlyta (axitinib) is an orally administered prescription medication that is used to treat renal cell carcinoma (RCC), also known as renal cell cancer. RCC begins in the cells of the kidneys. Inlyta treats RCC that has spread to other areas of the body (metastasized).
This medication is approved for adults aged 18 and older. It is either used alone or in combination with other cancer-fighting medications.
Inlyta is administered in the form of a tablet that is taken by mouth. It is in a class of medications called tyrosine kinase inhibitors (TKIs). These drugs are referred to as cancer blockers.
TKIs are used to restrain (inhibit) tyrosine kinases. They are also categorized as a kind of protein catalysts that speed chemical reactions in the body (enzymes). TKIs work by blocking the overly active enzymes inside cancer cells from growing and spreading.
Inlyta also works against the vascular endothelial growth factor (VEGF) pathway, which keeps cancer cells from being able to make blood vessels.
VEGF is a substance created by cells to stimulate the formation of blood vessels.
Inlyta is not available as a generic product; however, the active ingredient in the medication, axitinib, is available as a brand-name drug in the form of oral tablets.

What Is Inlyta Used For?
The Food and Drug Administration (FDA) has approved Inlyta to treat RCC which has advanced and spread to areas of the body outside of the kidney.
Inlyta is a kinase inhibitor indicated for use:
- In combination with avelumab for the first-line (initial) treatment of patients with RCC
- In combination with pembrolizumab for the first-line treatment of patients with advanced RCC
- As a single agent for the treatment of advanced RCC after the failure of one prior therapy that targets the entire body (systemic therapy)
Both avelumab and pembrolizumab are given as intravenous (IV) injections (immunotherapy infusions).
Additionally, Inlyta can be used alone in advanced RCC if another therapy has failed.
How to Take Inlyta
Inlyta should be taken twice a day, about 12 hours apart. The drug can be taken with or without food. However, you should avoid grapefruit and grapefruit juice when you are taking Inlyta. The tablets should be swallowed whole with a full glass of water.

If you vomit after taking the medicine, do not take another dose. Continue your regular dosing schedule as prescribed.
You may start on a low dose and gradually increase it. Your dose will depend on how well the drug works for you and the severity of any side effects that you have.

- There is limited data on the presence of axitinib in human milk and its subsequent effect on the breastfed infant. Since there is a potential for serious negative reactions in a breastfed infant from Inlyta, you should not breastfeed during treatment with Inlyuta and should avoid doing so for two weeks after you take your last dose.
- Inlyta is not approved for children under the age of 18. Discuss alternative RCC treatments with your healthcare provider.

What Are Reasons I Shouldn’t Take Inlyta?
If any of the following apply to you, discuss alternative treatments with your provider. Adjustments to your treatment may need to be made.
Allergies: You should not take Inlyta if you are allergic to axitinib or any of the ingredients that Inlyta contains. Since it is a combinational drug, you also need to be aware of any allergy to avelumab or pembrolizumab.
Pregnancy/breastfeeding: People who are pregnant or want to become pregnant should talk with their healthcare provider before starting treatment. People who could potentially bear children should use protection against pregnancy while taking the medication as well as for one week after taking the last dose. This warning also applies to those who may breastfeed while taking Inlyta.
Hypertension: Blood pressure should be well controlled before starting Inlyta. The drug has the potential to lead to high levels of hypertension which can become dangerous.
Heart disease: People with a history of heart problems should discuss their health with their provider before beginning Inlyta. In one clinical study, heart failure was reported in 2% of people treated with axitinib, and there were two deaths.
Slowed wound healing: Compromised wound healing can occur in people being treated with VEGF inhibitors, such as Inlyta. You will need to stop taking it two days before you have surgery. Do not take Inlyta for at least two weeks after having major surgery and until sufficient wound healing has occurred.
