Lartruvo is a medication used to treat a type of cancer called soft tissue sarcoma. Lartruvo is used with a chemotherapy called doxorubicin.
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 available in an injectable form to be given by slowly injecting the medication directly into a vein (IV infusion) by a healthcare professional over 60 minutes.
Your treatment will be scheduled in cycles. There are 3 weeks (21 days) in each treatment cycle. You will be given treatment on Days 1 and 8 of each 3-week (21-day) cycle.
On the first day of treatment, you will receive both Lartruvo and doxorubicin. On the 8th day, you will receive Lartruvo only.
Your healthcare team will decide the appropriate length of treatment.
Your treatment plan may include Lartruvo and doxorubicin for up to 8 cycles of treatment. After the 8th cycle, your healthcare team may decide to continue treatment with Lartruvo alone. This will depend on the progress of your disease and how your body responds to therapy.
If your medicine changes, it may also affect the side effects you experience.
If your disease progresses at any point during treatment, your doctor will end treatment with Lartruvo and discuss with you the appropriate next steps on your treatment path.
Each Lartruvo infusion will last approximately 60 minutes. On the first day of the cycle, your Lartruvo dose will be given before doxorubicin.
You will receive medications before your Lartruvo infusion. This will help prepare your body for treatment with Lartruvo.
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.
If Lartruvo is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.
