Mechanism of Action

Gilteritinib is a potent selective inhibitor of both of the mutations, internal tandem duplication (ITD) and tyrosine kinase domain (TKD), of the FLT3 receptor. On the same note, gilteritinib also inhibits AXL and ALK tyrosine kinases. FLT3 and AXL are molecules involved in the growth of cancer cells. The activity of gilteritinib permits inhibition of the phosphorylation of FLT3 and its downstream targets such as STAT5, ERK, and AKT. The interest in FLT3 transmembrane tyrosine kinases was raised when studies reported that approximately 30% of the patients with acute myeloid leukemia presented a mutationally activated isoform. As well, the mutation ITD is associated with poor patient outcomes while the mutation TKD produces a resistance mechanism to FLT3 tyrosine kinase inhibitors and the AXL tyrosine kinase tends to produce a resistance mechanism to chemotherapies.

In preclinical trials, gilteritinib demonstrate an IC50 for the wild-type receptor of 5 nM, 0.7-1.8 nM for ITD-mutated, and comparable inhibition to other therapies in the TKD-mutated. As well, data showed a gilteritinib-driven inhibition of the receptor tyrosine kinase AXL which is known to modulate the activity of FLT3 in acute myeloid leukemia. Another important result _in vivo_ was the localization in high levels in xenografted tumors which indicated high selectivity. In phase 1/2 clinical trials, gilteritinib was shown to present a composite complete response of 41%, an overall response rate of 52%, a median duration of response of 20 weeks with a median overall survival of 31 weeks. In phase III clinical trials, gilteritinib reported a complete remission or complete remission with partial hematologic recovery in 21% of the patients.

Indications

  • Gilteritinib is indicated for the treatment of adult patients who have relapsed or refractory acute myeloid leukemia with an FLT3 mutation detected by an FDA-approved test. This indication was expanded for a companion diagnostic to include use with gilteritinib such as the LeukoStrat CDx FLT3 Mutation Assay. Acute myeloid leukemia is a cancer that impacts the blood and bone marrow with a rapid progression. This condition produces low numbers of normal blood cells and the requirement of a continuous need for transfusions.
  • Gilteritinib is an AXL receptor tyrosine kinase inhibitor used to treat relapsed or refractory acute myeloid leukemia.
  • Xospata is indicated as monotherapy for the treatment of adult patients who have relapsed or refractory acute myeloid leukemia (AML) with an FLT3 mutation.
  • Gilteritinib is an orally available small molecule inhibitor of FMS-like tyrosine kinase 3 (FLT3) which is used as an antineoplastic agent in the treatment of acute myeloid leukemia with FLT3 mutations.
  • Xospata is indicated as monotherapy for the treatment of adult patients who have relapsed or refractory acute myeloid leukemia (AML) with an FLT3 mutation.
  • For the treatment of adult patients who have relapsed or refractory acute myeloid leukemia (AML) with an FMS-like tyrosine kinase 3 (FLT3) mutation.

Drug Interactions

Drug-Food Interactions

  • Avoid grapefruit products. Grapefruit inhibits CYP3A metabolism, which may increase the serum concentration of gilteritinib.
  • Avoid St. John’s Wort. This herb induces CYP3A4 and p-glycoprotein, which may reduce the serum concentration of gilteritinib.
  • Take it at the same time every day.
  • Take it with or without food.

Pregnancy and Lactation

US FDA pregnancy category Not Assigned

Pregnancy

This medication should not be used during pregnancy due to the risk that it may cause harm to the unborn baby. If you become pregnant while taking this medication, contact your doctor immediately.

Lactation

It is not known if gilteritinib passes into breast milk. If you are breast-feeding and are taking this medication, it may affect your baby. Women are advised to avoid breastfeeding while taking this medication and for 2 months after taking the last dose.

How should this medicine be used?

Gilteritinib comes as a tablet to take by mouth. It is usually taken once daily with or without food for at least 6 months. Take gilteritinib at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take gilteritinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole with water; do not split, chew, or crush them.

Your doctor may adjust your dose or temporarily or permanently stop your treatment depending on how well the medication works for you and if you experience any side effects. Talk to your doctor about how you are feeling during your treatment. Continue to take gilteritinib even if you feel well. Do not stop taking gilteritinib without talking to your doctor.

What special precautions should I follow?

Before taking gilteritinib,

  • tell your doctor and pharmacist if you are allergic to gilteritinib, any other medications, or any of the ingredients in gilteritinib tablets. Ask your pharmacist for a list of the ingredients.
  • tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: certain antifungals such as fluconazole (Diflucan), itraconazole (Onmel, Sporanox), and ketoconazole; clarithromycin (Biaxin, in PrevPac); escitalopram (Lexapro); fluoxetine (Prozac); certain medications for human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) such as efavirenz (Sustiva, in Atripla), indinavir (Crixivan), nelfinavir (Viracept), nevirapine (Viramune), ritonavir (Norvir, in Kaletra), and saquinavir (Invirase); certain medications for seizures such as carbamazepine (Carbatrol, Epitol, Tegretol, others), phenobarbital, and phenytoin (Dilantin, Phenytek); nefazodone; pioglitazone (Actos); rifabutin (Mycobutin); rifampin (Rifadin, Rimactane, in Rifamate, in Rifater); and sertraline (Zoloft). Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with gilteritinib, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
  • tell your doctor what herbal products you are taking, especially St. John’s wort.
  • tell your doctor if you have or have ever had a QT interval prolongation (an irregular heart rhythm that can lead to fainting, loss of consciousness, seizures, or sudden death); a slow, fast, or irregular heartbeat; or low levels of potassium or magnesium in your blood.
  • tell your doctor if you are pregnant, plan to become pregnant, or if you plan to father a child. You or your partner should not become pregnant while you are taking gilteritinib. If you are female, you will need to have a pregnancy test at least 7 days before you start treatment, and you should use birth control during your treatment and for 6 months after your final dose. If you are male, you and your partner should use birth control to prevent pregnancy during your treatment and for 4 months after your final dose. Talk to your doctor about birth control methods that you can use during your treatment. If you or your partner become pregnant while taking gilteritinib, call your doctor. Gilteritinib may harm the fetus.
  • tell your doctor if you are breastfeeding. You should not breastfeed during your treatment with gilteritinib and for 2 months after your final dose.
