6.Contents of the pack and additional information

Reblozyl contains the active ingredient luspatercept. It is used for the following:

Mylodysplastic syndromes

Mylodysplastic syndromes (MDS) are a group of diverse blood and bone marrow disorders.

• Red blood cells show alterations and do not develop correctly.

• Patients may present several signs and symptoms, including few red blood cells (anemia) and may require red blood cell transfusions.

Reblozyl is used in adults with anemia caused by MDS who require red blood cell transfusions. It is used in adults who have already received other treatments with erythropoietin or who cannot receive them.

Beta-thalassemia

Beta-thalassemia is a hereditary blood disorder.

• Affects the production of hemoglobin.
• Patients may present several signs and symptoms, including few red blood cells (anemia) and may require red blood cell transfusions.

Reblozyl is used for the treatment of anemia in adults with beta-thalassemia who may or may not require regular red blood cell transfusions.

How Reblozyl works

Reblozyl improves the body's ability to produce red blood cells. Red blood cells contain hemoglobin, a protein that transports oxygen throughout the body. When the body produces more red blood cells, the level of hemoglobin increases.

For patients with MDS and beta-thalassemia who require regular blood transfusions

The treatment with Reblozyl may prevent or reduce the need for red blood cell transfusions.

• Red blood cell transfusions can elevate iron concentrations in the blood and different organs of the body. This can be harmful in the long term.

For patients with beta-thalasemia who do not require regular blood transfusions

The treatment with Reblozyl may improve anemia by increasing the level of hemoglobin.

Do not use Reblozyl

• If you are allergic to luspatercept or any of the other components of this medication (listed in section6)
• If you are pregnant (see section on pregnancy)
• If you need treatment for the control of masses that produce blood cells outside of the bone marrow (extramedullary hematopoietic masses, HEM)

Warnings and precautions

Consult your doctor before starting treatment with this medication if:

• You haveβ‑thalassemia and have had your spleen removed. You may have a higher risk of forming a blood clot. Your doctor will discuss with you other possible factors that may increase this risk, such as:
• • hormone replacement therapy or
  • a previous blood clot

Your doctor may use preventive measures or medications to reduce the possibility of a blood clot.

• You have intense back pain that does not go away, numbness or weakness, or loss of voluntary movement in your legs, hands, or arms, fecal and urinary incontinence. These may be symptoms of HEM and spinal cord compression.
• You have had high blood pressure (because Reblozyl may increase it). Your blood pressure will be monitored before receiving Reblozyl and during treatment. Reblozyl will only be administered if your blood pressure is controlled.
• You have a condition that affects the strength and health of your bones (osteopenia and osteoporosis). You may be at risk of breaking your bones more easily.

Periodic analysis

You will have a blood test before each administration of this medication. This is because your doctor needs to verify that the hemoglobin concentration is adequate for treatment.

If you have kidney problems, your doctor may perform other tests.

Children and adolescents

This medication is not recommended for use in children and adolescents under 18years.

Total dose (mg) = dose level (mg/kg)×patient weight (kg), every three weeks.

Instructions for reconstitution

Reblozyl is supplied as a lyophilized powder for reconstitution with water for injection (API). A graduated syringe should be used during reconstitution to ensure the accuracy of the dose. See Table1.

Table1. Reconstitution table of Reblozyl

1.Remove the colored cap from the vial and clean the top with an alcohol wipe.

2.Add API to the vial using a graduated syringe with a needle, directing the flow towards the lyophilized powder. Let it rest for one minute.

3.Discard the syringe and needle used for reconstitution. Do not use them for subcutaneous injection.

4.Gently move the vial in a circular motion for 30seconds. Stop moving and let the vial stand upright for 30seconds.

5.Inspect the vial to verify that there is no undissolved powder in the solution. If undissolved powder is observed, repeat step4 until it is completely dissolved.

6.Invert the vial and gently move it in an inverted position for 30seconds. Place the vial back in the upright position and let it rest for 30seconds.

7.Repeat step6 seven times to ensure complete reconstitution of the material located on the sides of the vial.

8.Visually inspect the reconstituted solution before administration. If properly mixed, the reconstituted solution of Reblozyl is a colorless to yellowish, transparent to slightly opalescent solution in which no foreign particles are observed. Do not use if foreign particles or undissolved medicine are observed.

9.If the reconstituted solution is not used immediately, see the previous section,Storage of the medicine.

Administration form

If the reconstituted solution of Reblozyl has been refrigerated, it should be removed 15-30minutes before injection to reach room temperature. This will make the injection more comfortable.

The maximum recommended volume of the medicine per injection site is 1.2ml. If more than 1.2ml is needed, the total volume of Reblozyl should be divided into injections of similar volume and administered in separate areas in the same anatomical location, but on opposite sides of the body. Reconstitute the number of Reblozyl vials necessary to achieve the desired dose.

Inject Reblozyl subcutaneously in the arm, thigh, or abdomen.

If multiple injections are needed, use a new syringe and needle for each subcutaneous injection. Discard the unused content. Do not administer more than one dose from the same vial.

Elimination

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