1. What is Trabectedina Stada and what is it used for

This medicine contains the active substance trabectedin. Trabectedin is an anticancer medicine that works by preventing the multiplication of tumor cells.

Trabectedin is used to treat patients with advanced soft tissue sarcoma, when previous treatment with other medicines has not been effective or when patients cannot use other medicines. Soft tissue sarcoma is a malignant tumor that starts in the soft tissues, such as muscles, fat, or other tissues (e.g., cartilage or blood vessels).

Trabectedin in combination with pegylated liposomal doxorubicin (PLD, another anticancer medicine) is used to treat patients with ovarian cancer who have relapsed after at least one previous treatment and are not resistant to platinum-containing anticancer medicines.

2. What you need to know before you use Trabectedina Stada

Do not use Trabectedina Stada

• if you are allergic to trabectedin or any of the other ingredients of this medicine (listed in section 6);
• if you have a severe infection;
• if you are breastfeeding;
• if you are going to receive the yellow fever vaccine.

Warnings and precautions

Consult your doctor before starting to use this medicine.

You should not use trabectedin or its combination with PLD if you have severe liver, kidney, or heart problems.

Consult your doctor before starting treatment with trabectedin if you know or suspect that you have:

• Liver or kidney problems.
• Heart problems or a history of heart problems.
• A left ventricular ejection fraction (LVEF) below the lower limit of normal.
• Have received high-dose anthracycline treatment in the past.

Seek medical attention immediately if you experience any of the following:

• If you have a fever, as trabectedin can cause side effects that affect the blood and liver.

• If, despite taking anti-nausea medication, you experience nausea, vomiting, or are unable to drink fluids and therefore urinate less, seek medical attention immediately.

• If you notice severe muscle pain or weakness, as it could be a sign of muscle damage (rhabdomyolysis, see section 4).

• If you notice that the trabectedin infusion is leaking out of the vein during administration. This could damage or destroy the cells of the tissues near the injection site (tissue necrosis; see also section 4), which may require surgical intervention.

• If you have an allergic reaction (hypersensitivity). In this case, you may experience one or more of the following symptoms: fever, difficulty breathing, redness or rash, feeling of dizziness (nausea) or feeling of discomfort (vomiting, see section 4).

• If you notice swelling or partial swelling without apparent cause (edema), possibly accompanied by dizziness, vertigo, or thirst (low blood pressure). This could be a manifestation of a disorder (capillary leak syndrome) that can cause excessive fluid accumulation in your tissues, requiring urgent clinical evaluation by your doctor.

Children and adolescents

Trabectedin should not be used in children under 18 years of age with pediatric sarcomas.

Other medicines and Trabectedina Stada

Tell your doctor if you are using, have recently used, or may need to use any other medicine.

You should not use trabectedin if you are going to receive the yellow fever vaccine, and it is not recommended if you are going to receive a vaccine containing live virus particles. The use of medicines containing phenytoin (for the treatment of epilepsy) with trabectedin is not recommended, as the effect of phenytoin may be reduced.

If you use any of the following medicines during your treatment with trabectedin, you will need to be closely monitored, as the effects of trabectedin are:

• reduced (e.g., using medicines containing rifampicin (for bacterial infections), phenobarbital (for epilepsy), or St. John's Wort (Hypericum perforatum, a medicinal plant used to treat depression)) or

• increased (e.g., medicines containing ketoconazole or fluconazole (for fungal infections), ritonavir (for HIV infection), clarithromycin (for bacterial infections), aprepitant (to prevent nausea and vomiting), cyclosporine (immunosuppressant), or verapamil (for hypertension and other heart conditions)).

The use of trabectedin with any of these medicines should be avoided if possible.

If, in addition to trabectedin or the combination of trabectedin and PLD, you are receiving another medicine that can cause liver or muscle damage (rhabdomyolysis), you may be closely monitored, as the risk of liver or muscle damage may increase. Medicines containing statins (to reduce cholesterol levels and prevent cardiovascular disease) are an example of medicines that can cause muscle damage.

Using Trabectedina Stada with alcohol

Alcohol consumption should be avoided during treatment with trabectedin, as it can damage the liver.

Pregnancy, breastfeeding, and fertility

Pregnancy

Trabectedina should not be used during pregnancy. If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

Women of childbearing age should use effective contraceptive methods during treatment with trabectedina and for up to 3 months after the end of treatment.

If you become pregnant, you should inform your doctor immediately; additionally, genetic counseling is recommended, as trabectedin may cause genetic damage to the fetus.

Breastfeeding

Trabectedina should not be administered to patients who are breastfeeding. Therefore, before starting treatment, you should stop breastfeeding and not resume it until your doctor confirms that it is safe to do so.

Fertility

Men of childbearing age should use effective contraceptive methods during treatment with trabectedina and for up to 5 months after treatment.

Because there is a risk that treatment with trabectedin may cause irreversible infertility, it is recommended that patients seek advice on the possibility of preserving their eggs or sperm before treatment.

Genetic counseling is also recommended for those patients who wish to have children after treatment.

Driving and using machines

You may feel tired and weak during treatment with trabectedin. Do not drive or use tools or machines if you experience any of these side effects.

Trabectedina Stada contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per vial; this is essentially "sodium-free".

3. How to use Trabectedina Stada

Trabectedin should be administered under the supervision of a doctor with experience in the use of chemotherapy. Its use should be limited to qualified oncologists and other healthcare professionals specialized in the administration of cytotoxic medicines.

For the treatment of soft tissue sarcoma, the usual dose is 1.5 mg/m2 of body surface area. During the treatment period, your doctor will closely monitor you and decide what dose of trabectedin is most suitable for you. The recommended dose in Japanese patients is lower than the usual dose for other races and is 1.2 mg/m2 of body surface area.

For the treatment of ovarian cancer, the usual dose is 1.1 mg/m2 of body surface area after administration of 30 mg/m2 of body surface area of PLD.

Before administration, trabectedin should be reconstituted and diluted for intravenous use. Each time you receive trabectedin for the treatment of soft tissue sarcoma, it will take approximately 24 hours for the entire solution to enter your bloodstream. The treatment of ovarian cancer will last 3 hours.

In order to avoid irritation at the injection site, it is recommended that trabectedin be administered through a central venous line.

In order to protect the liver and reduce the risk of side effects such as nausea and vomiting, you will be given other medicines before treatment with trabectedin and whenever needed during treatment.

You will receive an infusion every 3 weeks, although your doctor may occasionally recommend delaying the dose so that you receive the most suitable dose of trabectedin.

The total duration of treatment will depend on your progress and how you feel. Your doctor will tell you how long your treatment may last. If you have any further questions about the use of this medicine, ask your doctor.

4. Possible side effects

Like all medicines, this medicine or its combination with PLD can cause side effects, although not everyone gets them.

If you are not sure what the following list means, ask your doctor to explain it to you in more detail.

Severe side effects caused by treatment with trabectedin:

Very common: may affect more than 1 in 10 people

• You may have elevated levels of the yellow pigment bilirubin in the blood, which can cause jaundice (yellowing of the skin, mucous membranes, and eyes).

• Your doctor will regularly ask for blood tests to detect any abnormalities in the blood.

Common: may affect up to 1 in 10 people

• You may have blood infections (septicemia) if your immune system is severely affected. If you have a fever, seek medical attention immediately.

• You may also feel muscle pain (myalgia). You may also experience nerve damage, which can cause muscle pain, weakness, and numbness. You may experience swelling or swelling of the extremities and a tingling sensation on the skin.

• You may have a reaction at the injection site. The trabectedin infusion may leak out of the vein during administration and cause damage and destruction of the cells of the tissues near the injection site (tissue necrosis; see also section 2 "Warnings and precautions"), which may require surgical intervention.

• You may have an allergic reaction. In this case, you may experience fever, difficulty breathing, redness or rash, feeling of dizziness (nausea) or feeling of discomfort (vomiting).

• When trabectedin is used with PLD, you may experience syncope or fainting. You may also notice that your heart beats too hard or too fast (palpitations), suffer from weakness in the ventricles, which are the main pumping chambers of the heart (left ventricular dysfunction), or have a sudden blockage of a pulmonary artery (pulmonary embolism).

Uncommon: may affect up to 1 in 100 people

• You may feel severe muscle pain and pain, stiffness, and muscle weakness. You may also experience darkening of the urine color. All of the above could be a sign of muscle damage (rhabdomyolysis).

• Your doctor may ask for blood tests in certain situations to prevent muscle damage (rhabdomyolysis). In some very severe cases, this muscle damage could lead to kidney failure. If you experience severe muscle pain or weakness, seek medical attention immediately.

• You may experience difficulty breathing, irregular heartbeat, decreased urine output, sudden changes in mental status, mottled skin, very low blood pressure associated with abnormal laboratory results (decreased platelet count). If you experience any of these symptoms or signs, seek medical attention immediately.

• You may have an abnormal accumulation of fluid in the lungs, which can cause swelling (pulmonary edema).

• You may notice swelling or partial swelling without apparent cause (edema), possibly accompanied by dizziness, vertigo, or thirst (low blood pressure). This could be a manifestation of a disorder (capillary leak syndrome) that can cause excessive fluid accumulation in your tissues. If this happens, seek medical attention immediately.

• You may notice that the trabectedin infusion is leaking out of the vein while it is being administered (extravasation). Therefore, you may notice redness, swelling, itching, and discomfort at the injection site. If you experience any of these symptoms or signs, tell your doctor or nurse immediately.

This could lead to tissue damage and death around the injection site (tissue necrosis), which may require surgery.

Some of the symptoms or signs of extravasation may not be visible until several hours after it occurs. Blisters, peeling, and darkening of the skin may appear in the area. It may take a few days for the extent of tissue damage to become visible. If you experience any of these symptoms or signs, seek medical attention immediately.

Rare: may affect up to 1 in 1,000 people

• You may experience yellowing of the skin and eyes (jaundice), pain in the upper right abdomen, nausea, vomiting, general feeling of discomfort, difficulty concentrating, disorientation, or confusion, drowsiness. These signs may indicate that the liver is not functioning normally. If you experience any of these symptoms or signs, seek medical attention immediately.

Other less serious side effects:

Very common: may affect more than 1 in 10 people

• You may:
• • feel tired
  • have difficulty breathing and coughing
  • notice back pain
  • have excess fluid in the body (edema)
  • develop bruises (hematomas) more easily
  • have nosebleeds
  • be more prone to infections. An infection can also cause fever
  • (fever).

If you experience any of these symptoms, seek medical attention immediately.

• You may also experience some digestive symptoms such as decreased appetite, nausea, or vomiting, abdominal pain, diarrhea, or constipation. If, despite taking anti-nausea medication, you experience nausea, vomiting, or are unable to drink fluids and therefore urinate less, seek medical attention immediately.

• You may have a headache.

• You may experience inflammation of the mucous membranes, which appears as redness and swelling of the inside of the mouth, causing painful ulcers and sores (stomatitis), or as inflammation of the gastrointestinal tract, when trabectedin is used with PLD.

• Patients receiving trabectedina with PLD for ovarian cancer may also experience hand-foot syndrome. It appears as redness of the skin on the palms of the hands, fingers, and soles of the feet, which can swell and turn purple over time. The lesions can be dry and scaly or blistering with ulcers.

Common: may affect up to 1 in 10 people

• You may experience fluid loss, weight loss, digestive discomfort, and altered sense of taste.

Detailed information about this medicine is available on the website of the Spanish Agency for Medicines and Health Products (AEMPS) (http://www.aemps.gob.es/).

This information is intended only for healthcare professionals:

Instructions for Use, Preparation, Handling, and Disposal

The correct procedures should be followed for the proper handling and disposal of cytotoxic medicines. The disposal of unused medicine and all materials that have come into contact with it will be carried out in accordance with local regulations for cytotoxic medicines.

The healthcare professional should have received training in the correct techniques for reconstituting and diluting trabectedina or its combination with DLP, and during the reconstitution and dilution of the drug, should wear protective clothing, including a mask, protective glasses, and gloves. Accidental contact with the skin, eyes, or mucous membranes should be treated immediately with a large amount of water. If you are pregnant, you should not work with this medicine.

Preparation for Intravenous Infusion

Trabectedina should be reconstituted and then diluted before infusion (see also section 3).

Appropriate aseptic techniques should be used.

Trabectedina should not be administered mixed with other medicines that are not the diluent in the same infusion. No incompatibilities have been observed between trabectedina and type I glass vials, or with polyvinyl chloride (PVC) and polyethylene (PE) bags and tubes, or with polyisoprene reservoirs or implantable titanium vascular access systems.

When trabectedina is used in combination with DLP, the intravenous line should be flushed well with 50 mg/ml (5%) glucose solution for infusion after administration of DLP and before administration of trabectedina. The use of any diluent other than 50 mg/ml (5%) glucose solution for infusion may cause precipitation of DLP. (See also the summary of product characteristics of DLP, which contains specific instructions for its handling).

Reconstitution Instructions

Trabectedina 0.25 mg:inject 5 ml of sterile water for injectable preparations into the vial.

Trabectedina 1 mg:inject 20 ml of sterile water for injectable preparations into the vial.

A syringe should be used to inject the correct amount of sterile water for injectable preparations into the vial. Shake the vial until the drug is completely dissolved. The reconstituted solution is clear, colorless, or slightly yellowish, without visible particles.

The reconstituted solution has a concentration of 0.05 mg/ml of trabectedina. It requires further dilution and is intended for single use.

Dilution Instructions

Dilute the reconstituted solution with a 9 mg/ml (0.9%) sodium chloride solution for infusion or a 50 mg/ml (5%) glucose solution for infusion. Calculate the required volume as follows:

SC = body surface area

The appropriate amount of reconstituted solution should be withdrawn from the vial; if intravenous administration is to be performed through a central venous line, add the reconstituted solution to an infusion bag containing ≥ 50 ml of diluent (9 mg/ml (0.9%) sodium chloride solution for infusion or 50 mg/ml (5%) glucose solution for infusion), with a trabectedina concentration in the infusion solution ≤ 0.030 mg/ml.

If a central venous line cannot be used and a peripheral venous line must be used, the reconstituted solution should be added to an infusion bag containing ≥ 1,000 ml of diluent (9 mg/ml (0.9%) sodium chloride solution for infusion or 50 mg/ml (5%) glucose solution for infusion).

Before intravenous administration, a visual inspection of the parenteral solutions should be performed to detect any possible presence of particles. Once the infusion is prepared, it should be administered immediately.

Stability of the Solutions During Use

Reconstituted Solution

After reconstitution, chemical and physical stability has been demonstrated for 30 hours up to 25 °C or up to 21 days if stored between 2 °C and 8 °C.

From a microbiological point of view, the reconstituted solution should be diluted and used immediately. If it is not diluted and used immediately, the storage times in use and conditions before use of the reconstituted solution will be the responsibility of the user and should not normally exceed 24 hours at 2 °C - 8 °C, unless the reconstitution has been performed in validated and controlled aseptic conditions.

Diluted Solution

After dilution, chemical and physical stability has been demonstrated for 30 hours up to 25 °C.
