Patient information: uses, side effects, how to take - Saphnelo

What is SAPHNELO?

  • SAPHNELO is a prescription medicine used to treat adults with moderate to severe systemic lupus erythematosus (SLE or lupus) who are receiving other lupus medicines.
  • SAPHNELO contains anifrolumab-fnia which is in a group of medicines called monoclonal antibodies. Lupus is a disease of the immune system (the body system that fights infection). When given together with other medicines for lupus, SAPHNELO may help to reduce your lupus disease activity more than other lupus medicines alone.
  • It is not known if SAPHNELO is effective in people with severe active lupus nephritis or central nervous system lupus.
  • It is not known if SAPHNELO is safe and effective in children.

Do not use SAPHNELO if you:

  • are allergic to anifrolumab-fnia or any of the ingredients in SAPHNELO. See the end of this Patient Information leaflet for a complete list of ingredients in SAPHNELO.

Before you receive SAPHNELO, tell your healthcare provider about all of your medical conditions, including if you:

  • think you have an infection or have infections that keep coming back. You should not receive SAPHNELO if you have an infection unless your healthcare provider tells you to. See “What are the possible side effects of SAPHNELO?”
  • are scheduled to receive a vaccination or if you think you may need a vaccination. You should not receive live vaccines during treatment with SAPHNELO.
  • have or have had any type of cancer.
  • are receiving other biologic medicines or monoclonal antibodies.
  • are pregnant or plan to become pregnant. It is not known if SAPHNELO will harm your unborn baby. Tell your healthcare provider if you are pregnant, think you might be pregnant, or plan to become pregnant during your treatment with SAPHNELO.

  • Pregnancy Exposure Registry. If you become pregnant while receiving SAPHNELO, talk to your healthcare provider. A pregnancy exposure registry monitors pregnancy outcomes in women exposed to SAPHNELO. You can find out more information about the registry by calling AstraZeneca at 1-877-693-9268.
  • are breastfeeding or plan to breastfeed. It is not known if SAPHNELO passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby while receiving SAPHNELO.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. SAPHNELO may affect the way other medicines work, and other medicines may affect how SAPHNELO works.

How will I receive SAPHNELO?

SAPHNELO is intended for use under your healthcare provider’s care and may be administered as an intravenous infusion or as a subcutaneous injection.

When given into a vein (intravenously)

  • Your healthcare provider will give you SAPHNELO through a needle placed in a vein (IV or intravenous infusion). It takes about 30 minutes to give you the full dose of SAPHNELO.
  • SAPHNELO is usually given 1 time every 4 weeks.
  • If you miss an appointment, call your healthcare provider as soon as possible to reschedule your appointment.

When given under the skin (subcutaneously)

  • SAPHNELO may be prescribed as a single-dose prefilled syringe or as a single-dose autoinjector (SAPHNELO PEN).
  • Use SAPHNELO exactly as your healthcare provider tells you to use it.
  • SAPHNELO is injected under your skin (subcutaneously) in your stomach (abdomen), thigh or upper arm (for caregiver administration only) 1 time every week.
  • Before you use SAPHNELO, your healthcare provider will train you or your caregiver how to give the injections.
  • Read the Instructions for Use that comes with SAPHNELO for information on how to prepare and inject SAPHNELO.
  • If you miss your dose of SAPHNELO inject a dose as soon as you remember. Then, continue to inject 1 time each week based on the new day SAPHNELO was injected or at your regularly scheduled time as long as there are at least 3‑days between the doses. In case you are not sure when to inject SAPHNELO, call your healthcare provider.

What are the possible side effects of SAPHNELO?

SAPHNELO may cause serious side effects, including:

  • Serious Infections. SAPHNELO can lower the ability of your immune system to fight infections. You may be at a higher risk of developing respiratory infections, and shingles (herpes zoster) during treatment with SAPHNELO. Infections (including COVID-19) could be serious, leading to hospitalization or death. Tell your healthcare provider right away if you have any of the following symptoms of an infection:
  • fever, sweating, or chills
  • muscle aches
  • cough
  • shortness of breath
  • burning when urinating
  • urinating more often
  • diarrhea or stomach pain
  • warm, red, or painful skin or sores on your body.
  • Allergic (hypersensitivity) reactions, including anaphylaxis. Serious allergic reactions can happen during or after you get your SAPHNELO infusion or take your SAPHNELO injection. Tell your healthcare provider or get emergency help right away if you have any of the following symptoms of a serious allergic reaction:
  • swelling of your face, mouth, and tongue
  • breathing problems
  • fainting or dizziness
  • feeling lightheaded (low blood pressure)
  • Cancer. SAPHNELO may reduce the activity of your immune system. Medicines that affect the immune system may increase your risk of certain cancers.

The most common side effects of SAPHNELO include:

  • upper respiratory infections
  • infusion reactions (when given intravenously)
  • cough
  • bronchitis
  • shingles (herpes zoster)

These are not all of the possible side effects of SAPHNELO.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1‑800-FDA-1088.

How should I store SAPHNELO?

  • Store SAPHNELO prefilled syringe and autoinjector in a refrigerator between 36°F to 46°F (2°C to 8°C) in the original carton to protect from light.
  • If needed, the SAPHNELO prefilled syringe or autoinjector (SAPHNELO PEN) can be stored at room temperature between 68°F to 77°F (20°C to 25°C) for up to 7 days protected from light. After the SAPHNELO prefilled syringe or autoinjector has reached room temperature, do not return to the refrigerator. Throw away SAPHNELO prefilled syringe or autoinjector if not used within 7 days at room temperature storage.
  • Do not shake SAPHNELO.
  • Do not freeze SAPHNELO.
  • Do not expose SAPHNELO to heat.
  • Do not use SAPHNELO past the expiration date.
  • Keep SAPHNELO and all medicines out of the reach of children.

Injecting using your SAPHNELO prefilled syringe
Step 4 – Choose an injection site

You or your caregiver can inject in the front of your thigh or the lower part of your stomach (abdomen).

A caregiver may also inject your upper arm.

Do not try to inject yourself in the upper arm.

Choose an injection site that is at least 1-inch (3 cm) away from where you last injected.

Do not inject:

  • into the 2-inch (5 cm) area around your belly button.
  • where the skin is red, warm, tender, bruised, scaly or hard.
  • into scarred, damaged, discolored or tattooed skin.
  • through clothing.
Step 5 – Wash your hands and clean the injection site

Wash your hands well with soap and water.

Clean the injection site with an alcohol wipe or with soap and water. Let the site air dry.

  • Do not touch the cleaned injection site again or blow on it before injecting.
Step 6 – Pull off the needle cover

Hold the SAPHNELO prefilled syringe body with 1 hand and carefully pull the needle cover straight off with your other hand.

  • Do not twist or wiggle the needle cover to remove it.
  • Do not touch or pull the plunger or plunger head while removing the needle cover.
  • You may see a drop of liquid at the end of the needle. This is normal.
  • Do not recap the needle. Put the needle cover to the side to throw it in the trash later.

Inject using the SAPHNELO prefilled syringe by following the steps in figures a, b, and c.

Using a 45 degree angle, fully insert the needle into the pinched skin.

Do not reposition the SAPHNELO prefilled syringe after you insert the needle into the skin.

Use your thumb to push down the plunger head.

To make sure you inject all the medicine and activate the needle guard, keep pushing firmly on the plunger head until it is fully down as far as it will go.

Slowly let go of the plunger head until the needle guard covers the needle.

If the needle is not covered, carefully throw away (dispose of) the SAPHNELO prefilled syringe right away (see Step 9).

  • can be closed with a tight-fitting puncture resistant lid, without sharps being able to come out,
  • upright and stable during use,
  • leak resistant, and
  • properly labelled to warn of hazardous waste inside the container.
