Lartruvo

Lartruvo is a prescription medication used to treat soft tissue sarcoma (STS), a type of cancer that begins in soft tissues such as muscles, fat, tendons, nerves, blood vessels or other supporting tissue.

Lartruvo belongs to a group of drugs called human monoclonal antibodies and specifically binds to and blocks the activity of platelet-derived growth factor receptor alpha (PDGFR-alpha). Blocking PDGFR-alpha will help to slow or stop the growth of cancer cells.

This medication helps to improve progression-free survival in patients with advanced or metastatic soft-tissue sarcoma. 

Lartruvo is given by intravenous (IV) infusion in a doctor's office, hospital, or infusion center.

Common side effects include nausea, fatigue, muscle pain, diarrhea and hair loss. 

Lartruvo is a prescription medication used in combination with a type of chemotherapy called doxorubicin to treat soft tissue sarcoma. Lartruvo helps to improve progression-free survival in patients with advanced or metastatic soft-tissue sarcoma that cannot be successfully treated by radiation or surgery. 

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information. 

The recommended Lartruvo dosing for the treatment of soft tissue sarcoma is as follows:

• The recommended dose of Lartruvo is based on your weight (15 mg/kg).
• Lartruvo is administered as an intravenous infusion over 60 minutes on Days 1 and 8 of each 21-day cycle.
• Lartruvo is continued until disease progression or unacceptable toxicity.
• For the first 8 cycles, Lartruvo is administered along with the chemotherapy agent doxorubicin.

It is important to keep all of your appointments to receive your Lartruvo dose.

If side effects become intolerable, you may need to wait longer between doses, receive a lower dose, or permanently stop the medicine if potentially serious side effects occur. 

Infusion reactions: Infusion reactions related to Lartruvo injections have occurred. Most of these reactions happened during or after the first or second Lartruvo injection. If this occurs, your doctor will decide to either slow the rate at which Lartruvo is injected into your veins or will stop the injection altogether. Tell your doctor or get medical help right away if you get any of these symptoms during or after an infusion this medication:

It has been shown that women taking Lartruvo during pregnancy may have babies born with serious problems. There are no situations where the benefits of the medication for the mother outweigh the risks of harm to the baby. These medicines should never be used by pregnant women.

Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant during your treatment with Lartruvo and for 3 months after your final dose.

Do not breastfeed while being treated with Lartruvo or for 3 months after a dose. 

It is not known if Lartruvo crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, women should not breastfeed during treatment with Lartruvo and for 3 months following the last dose. Contact your healthcare provider right away if you are being treated with Lartruvo and plan to breastfeed.
