1. What is Reblozyl and what is it used for

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

Myelodysplastic syndromes

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

• Red blood cells are abnormal and do not develop properly.

• Patients may have various signs and symptoms, including a lack of red blood cells (anemia) and may need red blood cell transfusions.

Reblozyl is used in adults with anemia caused by MDS who need 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 problem.

• It affects the production of hemoglobin.
• Patients may have various signs and symptoms, including a lack of red blood cells (anemia) and may need red blood cell transfusions.

Reblozyl is used to treat anemia in adults with beta-thalassemia who may or may not need 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 carries oxygen throughout the body. When the body produces more red blood cells, hemoglobin levels increase.

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

Treatment with Reblozyl may avoid or reduce the need for red blood cell transfusions.

• Red blood cell transfusions can increase iron levels in the blood and in various organs of the body. This can be harmful in the long term.

For patients with beta-thalassemia who do not need regular blood transfusions

Treatment with Reblozyl may improve anemia by increasing hemoglobin levels.

2. What you need to know before you are given Reblozyl

Do not use Reblozyl

• if you are allergic to luspatercept or any of the other ingredients of this medicine (listed in section 6)
• if you are pregnant (see section on pregnancy)
• if you need treatment to control the production of blood cells outside the bone marrow (extramedullary hematopoietic masses, HEM masses)

Warnings and precautions

Talk to your doctor before starting treatment with this medicine if:

• You have beta-thalassemia and have had your spleen removed. You may have a higher risk of forming a blood clot. Your doctor will discuss 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 risk of a blood clot.

• You have severe back pain that does not go away, numbness or weakness or loss of movement in your legs, arms, or hands, or loss of bowel or bladder control. These may be symptoms of extramedullary hematopoietic masses (HEM masses) and spinal cord compression.
• You have ever had high blood pressure (because Reblozyl may increase it). Your blood pressure will be checked before you receive Reblozyl and throughout treatment. You will only be given Reblozyl if your blood pressure is under control.
• 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.

Regular tests

You will have a blood test before each administration of this medicine. This is because your doctor needs to check that your hemoglobin levels are suitable for treatment.

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

Dose calculation

The total dose, based on the patient's weight (kg), is calculated as follows:

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 injections (API). A graduated syringe should be used during reconstitution to ensure dose accuracy. See Table 1.

Table1. Reblozyl reconstitution table

1. Remove the color cap from the vial and clean the top with an alcohol swab.
2. Add API to the vial using a graduated syringe with a needle, directing the flow towards the lyophilized powder. Let it stand for 1 minute.
3. Discard the needle and syringe used for reconstitution. Do not use them for subcutaneous injection.
4. Gently swirl the vial in a circular motion for 30 seconds. Stop swirling and let the vial stand upright for 30 seconds.
5. Inspect the vial to ensure that there is no undissolved powder in the solution. If undissolved powder is observed, repeat step 4 until it is completely dissolved.
6. Invert the vial and gently swirl it upside down for 30 seconds. Place the vial back upright and let it stand for 30 seconds.
7. Repeat step 6 seven more times to ensure complete reconstitution of the material on the sides of the vial.
8. Visually inspect the reconstituted solution before administration. If mixed correctly, the reconstituted Reblozyl solution is a colorless to yellowish, clear to slightly opalescent solution, in which no foreign particles are visible. 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.

Method of administration

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

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

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

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

Disposal

Disposal of unused medicine and all materials that have come into contact with it should be done in accordance with local regulations.
