What is Azacitidina Seacross

Azacitidina is an anticancer agent that belongs to a group of medications called “antimetabolites”. This medication contains the active ingredient “azacitidina”.

What is Azacitidina Seacross used for

Azacitidina is used in adults who cannot receive a stem cell transplant to treat:

• High-risk myelodysplastic syndromes (MDS).
• Chronic myelomonocytic leukemia (CMML).
• Acute myeloid leukemia (AML).

These diseases affect the bone marrow and can cause problems in the normal production of blood cells.

How Azacitidina Seacross works

Azacitidina works by inhibiting the growth of cancer cells. Azacitidina is incorporated into the genetic material of cells (ribonucleic acid [RNA] and deoxyribonucleic acid [DNA]). It is believed to act by altering the way cells activate or deactivate genes by interfering with the production of new RNA and DNA. It is believed that these actions correct the problems of maturation and growth of healthy blood cells in the bone marrow that cause myelodysplastic disorders and kill cancer cells in leukemia.

Consult a doctor or nurse if you have any questions about how Azacitidina works or why you have been prescribed this medication.

No use Azacitidina Seacross

• If you are allergic to azacitidina or any of the other components of this medication (listed in section 6).
• If you have advanced liver cancer.
• During lactation.

Warnings and Precautions

Consult your doctor, pharmacist, or nurse before starting to use Azacitidina:

• If you have a decrease in platelet, red blood cell, or white blood cell count.
• If you have a kidney disease.
• If you have a liver disease.
• If you have ever had a heart disease or myocardial infarction, or have a history of lung disease

Azacitidina Seacross may cause a severe immune reaction called “differentiation syndrome” (see section 4).

Blood tests

Before starting treatment with Azacitidina and at the beginning of each treatment period (called “cycle”) blood tests will be performed. This is done to check that you have a sufficient number of blood cells and that your liver and kidneys are functioning correctly.

Children and Adolescents

The use of Azacitidina is not recommended in children and adolescents under 18 years.

Other Medications and Azacitidina Seacross

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication. This is because Azacitidina may affect the way other medications work. Similarly, other medications may affect the way Azacitidina works.

Recommendations for safe handling

Azacitidina Seacross is a cytotoxic medication and, like other potentially toxic compounds, caution should be exercised when handling and preparing azacitidina suspensions. The procedures for correct handling and disposal of cancer medications should be applied.

If azacitidina reconstituted comes into contact with the skin, the area should be washed immediately and thoroughly with water and soap. If it comes into contact with mucous membranes, it should be washed thoroughly with water.

Incompatibilities

This medication should not be mixed with others, except as mentioned below (see

“Reconstitution procedure”).

Reconstitution procedure

Azaditidina Seacross should be reconstituted with water for injection. The shelf life of the reconstituted medication can be extended by reconstituting it with refrigerated water for injection (between 2°C and 8°C). The following information is provided on the conservation of the reconstituted medication.

1.The following items should be mounted:

Vial(s) of azacitidina; vial(s) of water for injection; non-sterile surgical gloves; alcohol-moistened wipes; 5 ml injection syringes with needles.

2.4 ml of water for injection should be extracted from the syringe,

ensuring that the air trapped inside the syringe is purged.

3.The needle of the syringe containing the 4 ml of water for injection should be inserted through the rubber stopper of the azacitidina vial; then, the water for injection should be injected into the vial.

4.After extracting the syringe and needle, the vial should be shaken vigorously, until a uniform turbid suspension is obtained. After reconstitution, each ml of suspension will contain 25 mg of azacitidina (100 mg/4 ml). The reconstituted product is a turbid and homogeneous suspension, without aggregates.The suspension should be discarded if it contains large particles or aggregates. Do not filter the suspension after reconstitution, as this may eliminate the active ingredient. Note that some adapters, infusion needles, and closed systems contain filters; therefore, these systems should not be used for administering the medication after reconstitution.

5.The rubber stopper should be cleaned and a new syringe with a needle should be introduced into the vial. Then, the vial should be inverted, ensuring that the needle tip is below the liquid level. Next, the plunger should be pulled back to extract the necessary amount of medication for the correct dose, ensuring that the air trapped inside the syringe is purged. Then, the syringe with the needle should be extracted from the vial and the needle should be discarded.

6.Next, a new subcutaneous needle (a gauge 25 needle is recommended) should be tightly attached to the syringe. The needle should not be purged before injection, in order to reduce the incidence of local reactions at the injection site.

7.If more than 1 vial is needed, all previous steps should be repeated for preparing the suspension. In the case of doses that require more than 1 vial, the dose should be divided into equal parts, for example, a dose of 150 mg = 6 ml; 2 syringes with 3 ml in each syringe. Due to retention in the vial and needle, it may not be possible to extract all the suspension from the vial.

8.The syringe contents should be resuspended immediately before administration. The loaded syringe containing the reconstituted suspension should be allowed to reach a temperature of approximately 20°C to 25°C for a maximum of 30 minutes before administration. If the time elapsed is greater than 30 minutes, the suspension should be discarded correctly and a new dose should be prepared. To resuspend, the syringe should be vigorously rolled between the palms of the hands, until a uniform turbid suspension is obtained.The suspension should be discarded if it contains large particles or aggregates.

Conservation of the reconstituted medication

For immediate use

The azacitidina Seacross suspension can be prepared immediately before use and the reconstituted suspension should be administered within the next 45 minutes. If the time elapsed is greater than 45 minutes, the reconstituted suspension should be discarded correctly and a new dose should be prepared.

For later use

When reconstituted with non-refrigerated water for injection, the reconstituted suspension should be placed in a refrigerator (temperature between 2°C and 8°C) immediately after reconstitution, and should be kept in the refrigerator for a maximum of 8 hours. If the time elapsed in the refrigerator is greater than 8 hours, the suspension should be discarded correctly and a new dose should be prepared.

When reconstituted with refrigerated water for injection (between 2°C and 8°C), the reconstituted suspension should be placed in a refrigerator (between 2°C and 8°C) immediately after reconstitution, and should be kept in the refrigerator for a maximum of 22 hours. If the time elapsed in the refrigerator is greater than 22 hours, the suspension should be discarded correctly and a new dose should be prepared.

The loaded syringe containing the reconstituted suspension should be allowed to reach a temperature of approximately 20°C to 25°C for a maximum of 30 minutes before administration. If the time elapsed is greater than 30 minutes, the suspension should be discarded correctly and a new dose should be prepared.

Calculation of an individual dose

The total dose, based on body surface area (SC), can be calculated as follows:

Total dose (mg) = dose (mg/m2) × SC (m2)

The following table is provided only as an example for calculating individual doses of azacitidina, based on an average SC value of 1.8 m2.

Form of administration

Do not filter the suspension after reconstitution.

Azacitidina Seacross reconstituted should be injected subcutaneously (insert the needle at an angle of 45 to 90°), with a gauge 25 needle, in the arm, thigh, or abdomen.

Doses greater than 4 ml should be injected in two separate locations.

The injection sites should be rotated. New injections should be administered at least 2.5 cm away from the previous site and never in sensitive areas, with ecchymosis, redness, or hardness.

The elimination of unused medication and all materials that have come into contact with it should be carried out in accordance with local regulations.
