Lutathera is a brand-name solution for IV infusion. It’s prescribed for certain rare cancers that affect the pancreas, stomach, intestines, and bowel. Lutathera contains the active ingredient lutetium-177 dotatate.

Drug details

You’ll find key information about Lutathera below.

Lutathera is available only as a brand-name medication. It’s not currently available in generic form.

A generic drug is an exact copy of the active ingredient in a brand-name medication. Generics usually cost less than brand-name drugs.

The following information describes dosages that are commonly used or recommended. However, your doctor will determine the best dosage to fit your needs.

Drug form and strength

Lutathera is a type of radiopharmaceutical, meaning it contains an active drug that releases small amounts of radiation. It comes as a liquid solution in single-use vials.

When prepared, each vial of Lutathera contains 370 megabecquerels of radioactivity per milliliter (MBq/mL) of solution. MBq is a unit that measures the amount of radiation in Lutathera.

The radioactivity of Lutathera decreases over time. To ensure that you receive the correct dose, a trained healthcare professional will measure the radiation of Lutathera right before giving the drug.

Each dose of Lutathera is measured in gigabecquerels (GBq). For reference, 1 GBq is equal to 1,000 MBq.

Dosage for certain neuroendocrine tumors

Lutathera is prescribed to treat gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in certain situations. These are rare tumors that affect the pancreas, stomach, intestines, and bowel. To learn more, see the “Lutathera uses” section.

The usual dose of Lutathera for GEP-NETs is 7.4 GBq. You’ll receive one dose every 8 weeks for a total of four doses.

Your doctor may give you a different dosage depending on the side effects you have during treatment. If you have questions about the Lutathera dosage that’s right for you, talk with your doctor.

Children’s dosage

Lutathera is prescribed to treat GEP-NETs in certain children ages 12 years and older.

The dosage of Lutathera for children is the same as for adults. For details, see “Dosage for certain neuroendocrine tumors.”

How Lutathera is given

You’ll receive Lutathera in a treatment facility that has been trained to handle radiopharmaceuticals. A healthcare professional will give Lutathera as an intravenous (IV) infusion over 30 to 40 minutes.

Your doctor will provide specific details about your Lutathera treatment protocol. This may include starting or stopping other medications before, during, and after your infusion.

You may also need to stay in the facility where you received the drug for several hours. This allows your doctor to watch closely for serious side effects. They’ll recommend how long you should stay in the facility.

If you have other questions about receiving Lutathera, talk with your doctor. You can also visit the drug manufacturer’s website.

If you have questions about Lutathera and fertility, talk with your doctor.

Lutathera and birth control

It’s not known whether Lutathera is safe to receive during pregnancy. If you’re sexually active and you or your partner can become pregnant, talk with your doctor about your birth control needs during Lutathera treatment.

For females receiving Lutathera

If you’re a female who can become pregnant and you engage in sexual activity that could lead to pregnancy, you should use effective birth control during Lutathera treatment. You should continue using birth control for at least 7 months after your final dose of the drug.

Lutathera is used to treat gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in adults. These are rare tumors that affect the pancreas, stomach, intestines, and bowel.

For this use, the cancer must be somatostatin receptor-positive. This means the tumor has receptors (attachment sites) for a hormone called somatostatin.

Lutathera is a type of radiopharmaceutical, meaning it contains an active drug that releases small amounts of radiation. Its mechanism of action (how it works) is to attach to somatostatin receptors on cancer cells. Lutathera then enters the cancer cells and releases radiation to kill them.

If you have other questions about how Lutathera works, talk with your doctor. You can also visit the drug manufacturer’s website.

Here are answers to some frequently asked questions about Lutathera.

How does Lutathera compare with Pluvicto?

Both Lutathera and Pluvicto are radiopharmaceuticals. Each contains a form of lutetium-177 as the active drug.

However, Lutathera and Pluvicto have different uses. Lutathera is used to treat certain gastroenteropancreatic neuroendocrine tumors. Pluvicto is used to treat metastatic prostate cancer in certain situations.

To learn more about how Lutathera and Pluvicto compare, talk with your doctor.

Is Lutathera a type of chemotherapy or another cancer treatment?

No, Lutathera is not a type of chemotherapy. Instead, it’s a radiopharmaceutical that delivers targeted radiation therapy to cancer cells.

Chemotherapy works by attacking rapidly dividing cells, including cancer cells and some healthy cells. Lutathera works differently. It attaches to cancer cells and releases radiation to kill them.

If you have questions about Lutathera and chemotherapy, talk with your doctor.

Should I follow any guidance on radiation safety with Lutathera?

Yes, you should follow radiation safety practices after Lutathera treatment. This is because small amounts of radiation leave your body through urine, sweat, and other fluids for a short time. While the risk to others is low, taking precautions helps reduce exposure to those around you.

Below are the precautions you might follow with Lutathera:

  • Drink plenty of fluids the day before, the day of, and the day after treatment to help flush out extra radiation.
  • Stay seated while using the toilet and flush twice after each use for at least 3 days.
  • Keep at least 3 feet of distance from others for at least 3 days.
  • Avoid close physical contact, including sexual activity, for at least 3 days.
  • Sleep in a separate bedroom from others for at least 3 days.
  • Shower daily and use separate towels and washcloths from others for at least 7 days.

The treatment facility where you’ll receive Lutathera may have other safety instructions. If you have questions, talk with your doctor.

Before receiving Lutathera, discuss your health history with your doctor. Lutathera may not be right for you if you have certain medical conditions or other factors affecting your health. Be sure to talk with your doctor if any of the following apply to you:

  • factors that increase the risk of kidney damage, such as diabetes or high blood pressure
  • previous allergic reaction to this or a similar drug
  • pregnancy
  • breastfeeding
