1. What Nplate is and what it is used for

The active substance of Nplate is romiplostim, a protein used to treat low platelet counts in patients with primary immune thrombocytopenia (ITP). ITP is a condition in which your body's immune system destroys its own platelets. Platelets are blood cells that help heal wounds and form blood clots. Very low platelet counts can cause serious bruising and bleeding.

Nplate is used in adult patients (18 years of age or older) with ITP, whether or not they have had their spleen removed, and who have been previously treated with corticosteroids or immunoglobulins that were not effective.

Nplate works by stimulating the bone marrow (the part of the bone that produces blood cells) to produce more platelets. This should help prevent bruising and bleeding associated with ITP.

2. What you need to know before using Nplate

Do not use Nplate

  • if you are allergic to romiplostim or to any of the other ingredients of this medicine (listed in section 6).

  • if you are allergic to other medicines produced using recombinant DNA technology that use the microorganism Escherichia coli (E. coli).

Warnings and precautions

  • If you stop taking Nplate, your platelet count is likely to return to low levels (thrombocytopenia). If you discontinue Nplate, your platelet count will need to be monitored, and your doctor will advise you on appropriate precautions.

  • If you are at risk of developing blood clots or if blood clots run in your family. The risk of blood clots may also be increased if you:

    • have liver problems;
    • are elderly (≥ 65 years of age);
    • are bedridden;
    • have cancer;
    • are taking contraceptive pills or hormone replacement therapy;
    • have recently undergone surgery or suffered an injury;
    • are obese (overweight);
    • are a smoker.

Consult your doctor, pharmacist, or nurse before starting to use Nplate.

If you develop a very high platelet count, your risk of blood clots may increase. Your doctor will adjust your dose of Nplate to ensure that your platelet count does not become too high.

Changes in bone marrow (increased reticulin and possible bone marrow fibrosis)

Long-term use of Nplate may cause changes in your bone marrow. These changes may lead to abnormal blood cells or reduced production of blood cells. A mild form of these bone marrow changes, called "increased reticulin," has been observed in clinical trials with Nplate. It is unknown whether this may progress to a more serious condition known as "fibrosis." Abnormal blood test results may indicate bone marrow changes. Your doctor will decide whether an abnormal blood test result means that a bone marrow examination should be performed or whether treatment with Nplate should be discontinued.

Worsening of blood cancer

Your doctor may decide to perform a bone marrow biopsy if it is necessary to confirm that you have ITP and not another condition such as Myelodysplastic Syndrome (MDS). If you have MDS and receive Nplate, you may experience an increase in blast cells and worsening of MDS, potentially progressing to acute myeloid leukemia, a type of blood cancer.

Loss of response to romiplostim

If you lose response to romiplostim or are unable to maintain a platelet response during treatment with romiplostim, your doctor will investigate the reasons, including whether you are developing increased bone marrow fibers (reticulin) or have developed neutralizing antibodies against romiplostim.

Children and adolescents

The use of Nplate is not recommended in children under 18 years of age.

Other medicines and Nplate

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

If you are also taking other medicines that prevent blood clotting (anticoagulant or antiplatelet therapy), there is an increased risk of bleeding. Your doctor will discuss this with you.

If you are taking corticosteroids, danazol, and/or azathioprine, which you may be receiving to treat your ITP, their dosage may need to be reduced or discontinued when used in combination with Nplate.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine. Nplate is not recommended during pregnancy unless specifically instructed by your doctor.

It is unknown whether romiplostim is excreted in human milk. The use of Nplate is not recommended during breastfeeding. The decision to discontinue breastfeeding or to discontinue romiplostim treatment should be made considering the benefits of breastfeeding for the infant and the benefits of romiplostim treatment for the mother.

Driving and using machines

Consult your doctor before driving or operating machinery, as some of the adverse effects (e.g., transient episodes of dizziness) may impair your ability to perform these activities safely.

3. How to use Nplate

Nplate must be administered under the direct supervision of a physician who carefully controls the amount of Nplate given.

Nplate is administered once weekly by subcutaneous injection (under the skin).

The starting dose is 1 microgram of Nplate per kilogram of body weight once a week. Your doctor will determine the amount of Nplate you should use. Nplate should be injected once a week to maintain platelet counts. Your doctor will take blood samples regularly to assess how your platelets are responding and adjust the dose if necessary.

Once your platelet count is controlled, your doctor will continue to monitor you with regular blood tests. Your dose may be adjusted later to maintain long-term control of your platelet count.

Always follow exactly the instructions for using Nplate provided by your doctor. If in doubt, consult your doctor again on how to use Nplate.

Instructions for preparing and administering an injection of Nplate

After adequate training, your doctor may allow you to self-inject Nplate. Please read the instructions at the end of this leaflet on how to inject Nplate, as discussed with your doctor. If your doctor has allowed you to self-inject, you must have monthly follow-up visits so your doctor can determine whether Nplate is working or whether another treatment should be considered.

After the first month of self-injecting Nplate, you will need to demonstrate that you are still able to prepare and inject Nplate correctly.

If you use more Nplate than you should

Your doctor will ensure that you receive the correct amount of Nplate. If you have received more Nplate than you should have, you may not experience any physical symptoms, but your blood platelet levels may rise to very high levels, which may increase the risk of blood clots. Therefore, if your doctor suspects that you have received too much Nplate, monitoring for any signs or symptoms of side effects is recommended, and appropriate treatment should be administered immediately.

If your doctor has allowed you to self-inject and you have used more Nplate than you should have, inform your doctor immediately.

If you use less Nplate than you should

Your doctor will ensure that you receive the correct amount of Nplate. If you have received less Nplate than you should have, you may not experience any physical symptoms, but your blood platelet levels may drop to low levels, which may increase the risk of bleeding. Therefore, if your doctor suspects that you have received less Nplate than you should have, monitoring for any signs or symptoms of side effects is recommended, and appropriate treatment should be administered immediately.

If your doctor has allowed you to self-inject and you have used less Nplate than you should have, inform your doctor immediately.

If you forget to use Nplate

If you miss a dose of Nplate, your doctor will advise you when to receive the next dose.

If your doctor has allowed you to self-inject and you missed your injection, inform your doctor immediately.

If you stop using Nplate

If you stop using Nplate, you are likely to develop a low platelet count again (thrombocytopenia). Your doctor will decide whether you should stop taking Nplate.

Self-injecting Nplate

Your doctor may decide it is best for you to inject Nplate yourself. Your doctor, nurse, or pharmacist will show you how to inject Nplate. Do not attempt to self-inject unless you have been trained. It is very important that you prepare Nplate correctly and take the correct dose (see section 7. Instructions for preparing and administering an injection of Nplate, at the end of this leaflet).

  1. Instructions for preparing and administering an injection of Nplate

This section contains information on how to self-inject Nplate. It is important that you do not attempt to self-administer the injection unless you have been trained by your doctor, nurse, or pharmacist. If you have any questions about how to give the injection, consult your doctor, nurse, or pharmacist. It is very important that the product is prepared correctly and that the correct dose is administered.

This section is divided into the following subsections:

Before you begin

Step 1. Arrange the injection materials

Step 2. Prepare the vial for use, attach the vial adapter

Step 3. Prepare the syringe with sterile water

Step 4. Reconstitute Nplate by injecting the water into the vial

Step 5. Prepare a new syringe for the injection

Step 6. Prepare the injection needle

Step 7. Choose and prepare the injection site

Step 8. Inject the Nplate solution

Step 9. Disposal of supplies

Before you begin

Read all the instructions carefully. These instructions are intended for patients who have already been trained by their healthcare professional, such as their doctor, nurse, or pharmacist, in self-injection. If you have not been trained, please contact your healthcare professional.

The Nplate self-injection kit must be kept in its original packaging until use to protect the Nplate vial from light. Store the Nplate self-injection kit refrigerated between 2°C and 8°C.

Once Nplate has been reconstituted, inject it immediately.

It is possible that some Nplate will remain after the prescribed dose has been administered. Do not reuse Nplate! Any reconstituted Nplate remaining after administration must be discarded immediately after completing the injection process. Leftover Nplate from the vial must NEVER be reused for another injection.

Step 1. Arrange the injection materials

Do the following:

  • Select a flat, well-lit work surface, such as a table.

  • Remove the Nplate self-injection kit from the refrigerator. Do not use if frozen. If you have any doubts about storage, contact your healthcare professional for further instructions.

  • Check the expiry date printed on the self-injection kit. If the expiry date has passed, do not use it. Do not proceed and inform your healthcare professional.

  • Note: If your doctor has indicated that your Nplate dose requires more than one injection, you will need to use more than one self-injection kit. Follow the steps described in this leaflet and use as many self-injection kits as necessary to complete the prescribed Nplate dose.

  • Ensure you have the following components:

Step 3. Prepare the sterile water syringe

Use: The pre-filled sterile water syringe and plunger.

Before starting Step 3, please note the following:

  • The transparent plastic plunger MUST always be attached before breaking off the white tip of the pre-filled sterile water syringe. Perform step 3a before step 3b.

Do the following:

  • Step 3a: Attach the clear plastic plunger to the prefilled sterile water syringe, by placing the threaded end of the plunger into the syringe and carefully turning the rod clockwise onto the gray plunger syringe until slight resistance is felt. Do not overtighten.

Step 4. Reconstitute Nplate by injecting the water into the vial

Use: Prefilled syringe of sterile water and vial with vial adapter attached.

Before starting Step 4, please note the following:

  • Reconstitute slowly and carefully. It is a protein and, as such, may be easily damaged by improper or excessive agitation.

Do the following:

  • Keeping the vial on the table, place the pre-filled water syringe into the vial adapter, holding one side of the vial adapter with one hand and, with the other hand, turn the syringe tip clockwise into the adapter until slight resistance is felt.

  • Dispose of the empty syringe in a sharps or hazardous waste container. Keep the dissolved Nplate vial. Immediately prepare a new syringe for injection.

  • Do not delay the Nplate injection.

Step 5. Prepare a new syringe for injection

Use: A new 1 ml syringe from the package, and the vial with dissolved and clear Nplate.

Before continuing:

  • Check your dose before starting this step.

  • Note: Liquid Nplate is very potent, so accurate measurement and dosing are important.

  • Ensure that all air bubbles have been removed before injection.

Do the following:

  • Remove a 1 ml syringe from the package.
  • Draw air into the syringe up to the 1 ml mark.
  • Do not pull the plunger beyond the 1 ml mark.

Step 7. Choose and prepare the injection site

Use: New alcohol wipes.

Do the following:

  • Select the injection sites. Three areas are recommended for Nplate injection.
  • Middle of the front of the thigh
  • Abdomen, except for the 5 cm area around the navel
  • If someone else is injecting you, the outer part of the upper arm may also be used
  • Rotate the different sites for each injection.

  • Do not inject in areas where the skin is soft, bruised, or hard.
  • Do not inject in areas with scars or stretch marks.
  • Clean the area where Nplate will be injected with an alcohol wipe, using a circular motion.
  • Do not touch the area again before injecting.

Step 9. Disposal of Supplies

Do the following:

  • Immediately dispose of the syringe with the covered needle into a sharps container.

  • Immediately dispose of the used Nplate vial into an appropriate waste container.

  • Ensure all remaining materials are discarded in the appropriate containers.

The injection device and Nplate vial MUST NEVER be reused.

  • Dispose of the used needle and syringe in a puncture-resistant container.

Dispose of any remaining Nplate in an appropriate waste container. Leftover material from an Nplate vial MUST NEVER be reused for another injection.
