What is Exkivity?

Exkivity is a prescription medicine used to treat adults with non-small cell lung cancer (NSCLC):

  • that has spread to other parts of the body (metastatic) and cannot be removed by surgery, and
  • has a certain abnormal epidermal growth factor receptor (EGFR) gene, and
  • whose disease has worsened while on or after chemotherapy that contains platinum

Your healthcare provider will perform a test to make sure that Exkivity is right for you.

It is not known if this medicine is safe and effective in children.

Important information

Exkivity may cause serious side effects, including:

  • Changes in the electrical activity of your heart called QTc prolongation and Torsades de Pointes. QTc prolongation can cause irregular heartbeats that can be life-threatening and may lead to death. Your healthcare provider will check the electrical activity of your heart with a test called an electrocardiogram (ECG) and do blood tests to check your electrolytes before starting, and during treatment. Tell your healthcare provider right away if you feel dizzy, lightheaded, faint or have an irregular heartbeat.

See Exkivity side effects for more information about side effects.

Before taking Exkivity

Before you start treatment, tell your healthcare provider about all of your medical conditions, including if you:

  • have heart problems, including a condition called long QTc syndrome
  • have problems with your electrolytes, such as sodium, potassium, calcium or magnesium
  • have lung or breathing problems other than lung cancer
  • are pregnant or plan to become pregnant. Exkivity can harm your unborn baby.
    Females who are able to become pregnant:
    • Your healthcare provider should do a pregnancy test before you start treatment.
    • You should use an effective form of non-hormonal birth control during treatment, and for 1 month after your last dose.
    • Birth control pills (oral contraceptives) and other hormonal forms of birth control may not work as well during treatment.
    • Talk to your healthcare provider about birth control methods that might be right for you during this time.
    • Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment.

Males who have female partners who are able to become pregnant:

    • You should use effective birth control during treatment and for 1 week after your last dose.
    • are breastfeeding or plan to breastfeed. It is not known if Exkivity passes into your breast milk. Do not breastfeed during treatment and for 1 week after your last dose.

Exkivity side effects

Exkivity may cause serious side effects, including:

See Important information.

Popular FAQ

How does Exkivity (mobocertinib) work?

Exkivity is a kinase inhibitor of epidermal growth factor receptor (EGFR). Kinases are enzymes that control different cell functions and may help cancer cells to grow. Specifically, Exkivity irreversibly attaches to and inhibits (blocks) EGFR exon 20 insertion mutations associated with non-small cell lung cancer (NSCLC) to help slow down tumor growth. It is a first-in-class oral therapy specifically designed to target EGFR Exon 20 insertion mutations.

Who manufactures Exkivity (mobocertinib)?

Exkivity is manufactured by Takeda Pharmaceuticals. The U.S. headquarters for Takeda is in Lexington, MA. You can contact the Oncology customer support team at Takeda Pharmaceuticals by calling 1-844-817-6468, option 2, M-F 8AM to 8PM, or online through the Takeda Oncology Here2Assist website.

Is Exkivity (mobocertinib) a chemotherapy drug?

Exkivity is not considered a chemotherapy treatment. It is a targeted anticancer drug therapy taken once a day as oral capsules. Targeted drug therapies find and attack specific types of cancer cells to help slow down tumor growth. Specifically, Exkivity is a first-in-class oral kinase inhibitor indicated for non-small cell lung cancer (NSCLC) with EGFR exon 20 insertion mutations.

There are no head-to-head comparative studies of Exkivity to Rybrevant, so it is not possible to say if one is better than the other. In clinical studies, both treatments led to responses in some patients: Close to 28% of patients had a partial response (tumor shrinkage) to Exkivity treatment and the response lasted for about 17.5 months. About 40% of participants had a response to Rybrevant treatment, and the duration of response (DoR) lasted for a median of 11.5 months. Continue reading

In clinical studies, 32 of 114 patients (28%) with NSCLC had a partial response to Exkivity treatment. In these patients, the response to treatment lasted for about 17.5 months. Close to 59% of patients who responded had a response that lasted at least 6 months Continue reading
