Spectral – Asparaginase uses, dose and side effects

}

10,000 U powder to concentrate to infusion liquid, solution
asparaginase

What Spectral is and what it is used for

Spectral contains asparaginase, which is an enzyme that interferes with natural substances that are necessary for cancer cells to grow. All cells need an amino acid called asparagine to continue living. Normal cells can produce their asparagine, but this is not the case for some cancer cells. Asparaginase lowers the level of asparagine in blood cancer cells and stops cancer growth.

Spectrila is used to treat adults and children with acute lymphoblastic leukemia (ALL), which is a form of blood cancer. Spectrila is used as a component of combination therapy.

What you need to know before you are given Spectrila

Spectrila must not be used

  • if you are allergic to asparaginase or the other ingredients of this medicine (listed in section 6)
  • if you have or have had inflammation of the pancreas ( pancreatitis )
  • if you have serious problems with liver function
  • if you have a blood clotting disorder (e.g. hemophilia )
  • if you have had serious bleeding or serious blood clots ( thrombosis ) during previous treatment with asparaginase.

Warnings and precautions

Talk to your doctor or nurse before you are given Spectrila.

The following life-threatening situations may occur during treatment with Spectrila:

  • severe inflammation of the pancreas ( acute pancreatitis )
  • liver problems
  • a severe allergic reaction that causes difficulty breathing or dizziness
  • blood coagulation disorders (bleeding or blood clot formation)
  • high blood sugar levels.

Before and during treatment with Spectrila, the doctor takes blood samples.

If serious liver problems occur, treatment with Spectrila must be stopped immediately.

If allergic symptoms occur, intravenous infusion with Spectrila must be stopped immediately. You may be given medication for allergies and, if necessary, medication to stabilize circulation. In most cases, treatment can be continued by changing to other medicines that contain other forms of asparaginase.

Disorders of blood clotting may require you to receive fresh blood plasma or a certain type of protein (antithrombin III) to reduce the risk of bleeding or blood clot formation ( thrombosis ).

High blood sugar levels may require treatment with intravenous fluids and/or insulin.

Reversible posterior leukoencephalopathy syndrome (characterized by headache, confusion, epileptic seizures, and loss of vision) may require antihypertensive drugs and, in cases of epileptic seizures, antiepileptic treatment.

Other medicines and Spectrila

Tell your doctor if you are using, have recently used, or might be using other medicines. This is important because Spectrila can increase the side effects of other medicines through its effect on the liver, which plays an important role in removing medicines from the body.

In addition, you must tell the doctor if you are using any of the following medicines:

  • Vincristine (used to treat certain types of cancer) because the simultaneous use of vincristine and asparaginase may increase the risk of certain side effects. To avoid this, vincristine is usually given 3–24 hours before asparaginase.
  • Glucocorticoid er (“cortisone”, anti-inflammatory drugs that inhibit the immune system) because the simultaneous use of glucocorticoid er and asparaginase can increase blood clot formation ( thrombosis ).
  • Medicines that reduce the blood’s ability to coagulate, e.g. anticoagulants (eg warfarin and heparin ), dipyridamole, aspirin, or medicines to treat pain and inflammation as the use of these medicines together with asparaginase may increase the risk of bleeding.
  • Medicines that are broken down in the liver (e.g. paracetamol, acetylsalicylic acid, tetracycline ), the risk of side effects, may increase.
  • Asparaginase can affect the effect of methotrexate or cytarabine (used to treat certain types of cancer):
    • if asparaginase is given after these drugs, their effect may be enhanced.
    • if asparaginase is given before these drugs, their effect may be weakened.
  • Medicines that can hurt liver function (eg paracetamol, acetylsalicylic acid, tetracycline ) because these negative effects can be aggravated by parallel treatment with asparaginase.
  • Medicines that can inhibit bone marrow function (eg cyclophosphamide, doxorubicin, methotrexate) as these effects may be enhanced by the parallel use of asparaginase. You may become more prone to infection.
  • Other anticancer drugs because can contribute to the release of too much uric acid when tumor cells are destroyed by asparaginase.

Vaccination

Simultaneous vaccination with live vaccines can increase the risk of a serious infection. Therefore, you should not be vaccinated with live vaccines until at least 3 months after finishing treatment with Spectrila.

Pregnancy and breastfeeding

There is a lack of information on the use of asparaginase in pregnant women. Spectrila must not be used during pregnancy unless the woman’s condition requires treatment with asparaginase. It is not known whether asparaginase is present in breast milk. Therefore, Spectrila should not be used during breastfeeding.

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, consult your doctor before using this medicine.

If you are sexually mature, you must use contraception or be abstinent during chemotherapy treatment and for 3 months after the end of treatment. Since an indirect effect between oral contraceptives and asparaginase cannot be excluded, oral contraceptives (taken by mouth) are not considered sufficiently safe. Women of childbearing age should use a contraceptive method other than oral contraceptives.

Driving ability and use of machinery

Do not drive or operate machinery while taking this medicine as it may make you feel drowsy, tired, or confused.

How Spectrila is used

Spectrila is prepared and given by healthcare professionals. The doctor decides what dose you will receive. The dose you receive depends on your body surface area, which is calculated from your height and weight.

Spectrila is given into a vein. It is usually given together with other anticancer drugs. The length of treatment depends on the specific chemotherapy protocol used to treat your disease.

Use for adults

The recommended dose of Spectrila for adults is 5,000 U (units) per square meter of the body surface and is given every three days.

Use for children and adolescents

The recommended dose for children and adolescents aged 1–18 years is 5,000 E per square meter of the body surface and is given every three days.

The recommended dose for infants aged 0–12 months is as follows:

  • younger than 6 months: 6,700 E per square meter of body surface
  • 6-12 months: 7,500 E per square meter of the body surface.

If you have been given too much Spectrila

If you think you have received too much Spectrila, tell the doctor or nurse as soon as possible.

So far, an overdose of asparaginase is not known to have led to any signs of an overdose. If necessary, the doctor treats your symptoms and provides supportive care.

If you have any further questions about this medicine, ask your doctor or nurse.
