This page tells you about the chemotherapy drug trabectedin. It is also called by its brand name Yondelis. There is information about
Trabectedin is a chemotherapy drug used to treat
- Advanced soft tissue sarcoma for people who have had treatment with ifosfamide and an anthracycline chemotherapy such as doxorubicin
- Ovarian cancer that has come back – you have trabectedin in combination with another chemotherapy drug called liposomal doxorubicin
Trabectedin works by sticking to the DNA in cells and damaging it. This stops the cancer cells growing and multiplying.
You have trabectedin into your bloodstream (intravenously). You can have it through a central line, a portacath, or a PICC line. These are long, plastic tubes that give the drugs directly into a large vein in your chest. You have the tube put in just before your course of treatment starts and it stays in place as long as you need it.
You usually have chemotherapy as a course of several cycles of treatment. The number of cycles of treatment you have depends on your treatment plan. The treatment plan for trabectedin depends on which type of cancer you have.
For soft tissue sarcoma you have trabectedin through a drip for 24 hours. Once the drip has finished you have no treatment for 3 weeks. Then you have your next treatment.
For ovarian cancer you have the drip for 3 hours the first time. If this goes well you can have the next treatment over an hour. You have treatment every 3 weeks.
You usually continue having the trabectedin for as long as it works.
There is detailed information about the way doctors plan chemotherapy in the planning chemotherapy section.
The side effects associated with trabectedin are listed below. You can use the links to find out more about each side effect. For general information, see our cancer drugs side effects section.
More than 10 in every 100 people have one or more of the side effects listed below.
A temporary drop in the number of blood cells made by the bone marrow, causing
- An increased risk of getting an infection from a drop in white blood cells – it is harder to fight infections and you can become very ill. You may have headaches, aching muscles, a cough, sore throat, pain passing urine or feel cold and shivery
- Tiredness and breathlessness due to a drop in red blood cells (anaemia) – you may need a blood transfusion
- Bruising more easily due to a drop in platelets – you may have nosebleeds, bleeding gums after brushing your teeth, or lots of tiny red spots or bruises on your arms or legs (known as petechia)
Some of these side effects can be life threatening, particularly infections. You should contact your doctor or nurse if you have any of these effects. Your doctor will check your blood counts before and during your treatment to see how well your bone marrow is working.
Other common side effects include
- Tiredness (fatigue) during and after treatment – most people find that they are back to normal after about 6 months
- Weakness and loss of strength

You won’t get all these side effects. Any that you do get may be mild. A side effect may get worse through your course of treatment. Or you may have more side effects as the course goes on. This depends on
- How many times you've had a drug before
- Your general health
- How much of the drug you have (the dose)
- Other drugs you are having
Talk to your doctor, pharmacist or nurse about all your side effects so they can help you manage them. They can give you advice or reassure you. Your nurse will give you a contact number to ring if you have any questions or problems. If in doubt, call them.
Tell your doctor about any other medicines you are taking, including vitamins, herbal supplements and over the counter remedies – some drugs can react together.
Some drugs or herbal medicines may make trabectedin work less well. These include
- Some antibiotics
- Some anti epileptic drugs
- St John's wort
Some drugs may increase the effects of trabectedin. These include
- Some medicines to treat fungal infections
- Some medicines for HIV/AIDS
- Some antibiotics
- Some anti sickness medicines
- Some drugs that lower immunity
- Drugs for high blood pressure and heart conditions
It is important not to drink alcohol while having trabectedin treatment as this may cause damage to the liver.
Trabectedin may have a harmful effect on a baby developing in the womb. Talk to your doctor or nurse about contraception before having treatment. Women need to use reliable contraception during treatment and for 3 months afterwards. Men should use reliable contraception during treatment and for 5 months afterwards.
Breastfeeding is not advisable during this treatment because the drug may come through in the breast milk.
You should not have immunisations with live vaccines while you are having chemotherapy or for at least 6 months afterwards. In the UK, these include rubella, mumps, measles (usually given together as MMR), BCG, yellow fever and Zostavax (shingles vaccine).
You can have other vaccines, but they may not give you as much protection as usual until your immune system has fully recovered from your chemotherapy. It is safe to have the flu vaccine.
It is safe for you to be in contact with other people who've had live vaccines as injections. There can be problems with vaccines you take by mouth (oral vaccines), but not many people in the UK have these now. So there is usually no problem in being with any baby or child who has recently had any vaccination in the UK. You might need to make sure that you aren't in contact with anyone who has had oral polio, cholera or typhoid vaccination recently, particularly if you live abroad.
