1. What Zessly is and what it is used for

Zessly contains the active substance infliximab. Infliximab is a monoclonal antibody – a type of
protein that binds to a specific target in the body called tumour necrosis factor (TNF) alpha.
Zessly belongs to a group of medicines known as "TNF blockers". It is used in adults to treat the
following inflammatory diseases:

  • Rheumatoid arthritis
  • Psoriatic arthritis
  • Ankylosing spondylitis (Bechterew’s disease)
  • Psoriasis

Zessly is also used in adults and children aged 6 years and older for:

  • Crohn’s disease
  • Ulcerative colitis

Zessly works by selectively binding to TNF alpha and blocking its action. TNF alpha is involved in
inflammatory processes in the body, so by blocking it, inflammation in the body can be reduced.

Rheumatoid arthritis
Rheumatoid arthritis is an inflammatory disease of the joints. If you suffer from rheumatoid arthritis,
you will initially be treated with other medicines. If these medicines do not work adequately, you will
be treated with Zessly in combination with another medicine called methotrexate to:

  • Reduce the signs and symptoms of the disease
  • Slow down the progression of joint damage
  • Improve physical function

Psoriatic arthritis
Psoriatic arthritis is an inflammatory disease of the joints, usually accompanied by psoriasis. If you
suffer from psoriatic arthritis, you will first be treated with other medicines. If these medicines do
not work adequately, you will be treated with Zessly to:

  • Reduce the signs and symptoms of the disease
  • Slow down the progression of joint damage
  • Improve physical function

Ankylosing spondylitis (Bechterew’s disease)
Ankylosing spondylitis is an inflammatory disease of the spine. If you suffer from ankylosing
spondylitis, you will first be treated with other medicines. If these medicines do not work adequately,
you will be treated with Zessly to:

  • Reduce the signs and symptoms of the disease
  • Improve physical function

Psoriasis
Psoriasis is an inflammatory skin disease. If you suffer from moderate to severe plaque psoriasis, you
will first be treated with other medicines or other treatments, such as phototherapy. If these
medicines or treatments do not work adequately, you will be treated with Zessly to reduce the signs
and symptoms of the disease.

Ulcerative colitis
Ulcerative colitis is an inflammatory bowel disease. If you suffer from ulcerative colitis, you will
first be treated with other medicines. If these medicines do not work adequately, you will be given
Zessly to treat the disease.

Crohn’s disease
Crohn’s disease is an inflammatory bowel disease. If you suffer from Crohn’s disease, you will first
be treated with other medicines. If these medicines do not work adequately, you will be treated with
Zessly to:

  • Treat active Crohn’s disease
  • Reduce the number of abnormal openings (fistulas) between the intestine and the skin, when other medicines or surgery have been inadequate

2. What you need to know before using Zessly

Do not use Zessly if:

  • You are allergic to infliximab or to any of the other ingredients of this medicine (listed in section 6).
  • You are allergic (hypersensitive) to mouse proteins.
  • You have tuberculosis (TB) or another serious infection such as pneumonia or sepsis.
  • You have moderate or severe heart failure.

Do not use Zessly if any of the above conditions apply to you. If you are unsure, speak with your doctor before receiving Zessly.

Warnings and precautions

Talk to your doctor before or during treatment with Zessly if you:

Have previously received treatment with any medicine containing infliximab

  • Inform your doctor if you have previously been treated with medicines containing infliximab and if you are restarting treatment with Zessly. If you have stopped treatment with infliximab for more than 16 weeks, there is an increased risk of allergic reactions when restarting treatment with Zessly.

Infections

  • Inform your doctor before receiving Zessly if you have an infection, even if it is very mild.
  • Inform your doctor before receiving Zessly if you have lived in or traveled to areas where fungal infections such as histoplasmosis, coccidioidomycosis, or blastomycosis are common. These infections are caused by specific types of fungi that can affect the lungs or other parts of the body.
  • You may be more susceptible to infections while being treated with Zessly. If you are 65 years of age or older, your risk is higher.
  • These infections can be serious and include tuberculosis, infections caused by viruses, fungi, bacteria, or other environmental organisms, and sepsis, which can be life-threatening. Inform your doctor immediately if you develop symptoms of infection during treatment with Zessly. Symptoms include fever, cough, flu-like symptoms, feeling unwell, skin redness or very warm skin, wounds, or dental problems. Your doctor may recommend temporarily stopping Zessly.

Tuberculosis (TB)

  • It is very important that you inform your doctor if you have ever had tuberculosis or if you have been in close contact with people who have had or currently have tuberculosis.
  • Your doctor will perform tests to assess whether you have tuberculosis. Cases of tuberculosis have been reported in patients treated with infliximab, including in patients who had previously been treated with anti-TB medications. Your doctor will record these test results on your patient reminder card.
  • If your doctor believes you are at risk of tuberculosis, you may be treated with anti-TB medications before starting Zessly. Inform your doctor immediately if you notice signs of tuberculosis during treatment with Zessly. Signs include persistent cough, weight loss, feeling tired, fever, and night sweats.

Hepatitis B virus

  • Inform your doctor before receiving Zessly if you are a carrier of hepatitis B or if you have previously had hepatitis B.
  • Inform your doctor if you think you may be at risk of contracting hepatitis B.
  • Your doctor must evaluate whether you have the hepatitis B virus.
  • Treatment with TNF blockers such as Zessly may cause reactivation of the hepatitis B virus in patients who are carriers of this virus, which in some cases can be fatal.

Heart problems

  • Inform your doctor if you have any heart problems, such as mild heart failure.
  • Your doctor will closely monitor your heart. Inform your doctor immediately if you notice new signs of heart failure or worsening symptoms during treatment with Zessly. Signs include shortness of breath or swelling in the feet.

Tumors and lymphoma

  • Inform your doctor before receiving Zessly if you have or have had lymphoma (a type of blood cancer) or other types of cancer.
  • Patients with severe rheumatoid arthritis who have had the disease for a long time may have an increased risk of developing lymphoma.
  • Children and adults taking Zessly may have an increased risk of developing lymphoma or other types of cancer.
  • Some patients treated with TNF blockers, including infliximab, have developed a rare type of cancer called hepatosplenic T-cell lymphoma. Most of these patients were adolescent or young male patients, and most had Crohn’s disease or ulcerative colitis. This type of cancer is usually fatal. Almost all patients had also been treated with medications containing azathioprine or 6-mercaptopurine in addition to TNF blockers.
  • Some patients treated with infliximab have developed certain types of skin cancer. If you notice changes in your skin or skin growths during or after treatment, inform your doctor.
  • Some women receiving treatment for rheumatoid arthritis with infliximab have developed cervical cancer. Your doctor may recommend regular cervical cancer screening for women taking Zessly, including women over 60 years of age.

Lung disease or heavy smokers

  • Inform your doctor before receiving Zessly if you have a lung disease called chronic obstructive pulmonary disease (COPD) or if you are a heavy smoker.
  • Patients with COPD who are heavy smokers may have an increased risk of cancer when treated with Zessly.

Nervous system disorders

  • Inform your doctor if you have or have had a nervous system disorder before receiving Zessly. This includes multiple sclerosis, Guillain-Barré syndrome, seizures, or a diagnosis of “optic neuritis.” Inform your doctor immediately if you notice symptoms of a nervous system disorder during treatment with Zessly. Signs include changes in vision, weakness in arms or legs, numbness, or tingling anywhere in the body.

Abnormal skin openings

  • Inform your doctor if you have any abnormal openings in the skin (fistulas) before receiving Zessly.

Vaccinations

  • Inform your doctor if you have recently been vaccinated or if you plan to be vaccinated.
  • You should receive recommended vaccinations before starting treatment with Zessly. You may receive certain vaccines during treatment with Zessly, but you must not receive live vaccines (vaccines containing a live, but weakened, infectious agent) while being treated with Zessly, as they may cause infections.
  • If you received Zessly during pregnancy, your baby may have an increased risk of infection following administration of a live vaccine during the first year of life. It is important to inform your pediatrician and other healthcare providers about your use of Zessly so they can determine when your baby should receive any vaccines, including live vaccines such as the BCG vaccine (used to prevent tuberculosis).
  • If you are breastfeeding, it is important to inform your pediatrician and other healthcare providers about your use of Zessly before any vaccines are given to your baby. Live vaccines should not be given to your baby during breastfeeding unless otherwise recommended by the pediatrician. For further information, see the section on Pregnancy and breastfeeding.

Infectious therapeutic agents

  • Talk to your doctor if you have recently received or plan to receive treatment with an infectious therapeutic agent (such as BCG instillation used to treat cancer).

Surgery or dental procedures

  • Inform your doctor if you are scheduled for any surgical or dental procedures.
  • Inform your surgeon or dentist that you are being treated with Zessly, and show them your patient reminder card.

Liver problems

  • Some patients treated with infliximab have developed serious liver problems.

Inform your doctor immediately if you experience symptoms of liver problems during treatment with Zessly. Symptoms include yellowing of the skin or eyes, dark brown urine, pain or swelling in the upper right part of the stomach, joint pain, skin rashes, or fever.

Reduction in blood cell count

  • In some patients treated with infliximab, the body may not produce enough blood cells that help fight infections or stop bleeding. Inform your doctor immediately if you experience symptoms of low blood cell count during treatment with Zessly. Symptoms include persistent fever, easy bleeding or bruising, small red or purple spots under the skin caused by bleeding, or paleness.

Immune system disorders

  • Some patients treated with infliximab have developed symptoms of an immune system disorder called lupus. Inform your doctor immediately if you develop symptoms of lupus during treatment with Zessly. Signs include joint pain or a rash on the cheeks or arms that is sensitive to sunlight.

Children and adolescents

The information above also applies to children and adolescents. In addition:

  • Some children and adolescent patients who have taken TNF-blocking medicines, such as infliximab, have developed tumors, including unusual types, some of which have been fatal.
  • Compared to adults, more children taking infliximab have developed infections.
  • Children should receive recommended vaccinations before starting treatment with Zessly. Children may receive certain vaccines during treatment with Zessly, but they must not receive live vaccines while being treated with Zessly.

If you are unsure whether any of the above conditions apply to you, contact your doctor before receiving Zessly.

Other medicines and Zessly

Patients with inflammatory diseases are often already taking medicines to treat their condition. These medicines may cause side effects. Your doctor will advise you which other medicines you should continue taking while on Zessly treatment.

Inform your doctor if you are taking or have recently taken any other medicines, including other medicines for Crohn’s disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, or psoriasis, or medicines obtained without a prescription, such as vitamins and herbal remedies.

In particular, inform your doctor if you are taking any of the following medicines:

  • Medicines that affect the immune system.
  • Kineret (anakinra). Zessly and Kineret must not be given together.
  • Orencia (abatacept). Zessly and Orencia must not be given together.

Live vaccines must not be administered during treatment with Zessly. If you used Zessly during pregnancy or are receiving Zessly while breastfeeding, inform your pediatrician and other healthcare providers about your use of Zessly before any vaccines are given to your baby.

If you are unsure whether any of the above conditions apply to you, contact your doctor before receiving Zessly.

Pregnancy, breastfeeding, and fertility

  • If you are pregnant, think you may be pregnant, planning to become pregnant, or are breastfeeding, consult your doctor before taking this medicine. Zessly should be used during pregnancy or breastfeeding only if your doctor considers it necessary.
  • You should avoid becoming pregnant while being treated with Zessly and for at least 6 months after stopping treatment. Talk to your doctor about using an appropriate contraceptive method during this time.
  • If you received Zessly during pregnancy, your baby may have an increased risk of infection.
  • It is important to inform your pediatrician and other healthcare providers about your use of Zessly before any vaccines are given to your baby. If you received Zessly during pregnancy, administering the BCG vaccine (used to prevent tuberculosis) to your baby within 12 months after birth may result in infection with serious complications, including death. Live vaccines such as the BCG vaccine should not be given to your baby within 12 months after birth unless otherwise recommended by the pediatrician. (For more information, see the section on Vaccinations.)
  • If you are breastfeeding, it is important to inform your pediatrician and other healthcare providers about your use of Zessly before any vaccines are given to your baby. Live vaccines should not be given to your baby during breastfeeding unless otherwise recommended by the pediatrician.
  • Severe decreases in white blood cell counts have been reported in infants born to women treated with infliximab during pregnancy. If your baby has persistent fever or infections, contact your baby’s doctor immediately.

Driving and using machines

Zessly is unlikely to affect your ability to drive or use machines. However, if you feel tired, dizzy, or unwell after treatment with Zessly, you should not drive or operate tools or machinery.

Zessly contains sodium

Zessly contains less than 1 mmol (23 mg) of sodium per dose, i.e., essentially “sodium-free.” However, before administration, Zessly is mixed with a solution containing sodium. Consult your doctor if you are on a low-salt diet.

Other sources of information
More detailed information on this medicinal product is available on the website of the European Medicines Agency, http://www.ema.europa.eu.

The following information is intended exclusively for healthcare professionals:

Patients treated with infliximab must be given the patient reminder card.

Instructions for use and handling – Storage conditions

Store at 2 °C – 8 °C.
Zessly may be stored at temperatures not exceeding 30 °C for a single period of up to 6 months, provided this does not extend beyond the original expiry date. The new expiry date must be recorded on the carton. After removal from the refrigerator, Zessly must not be returned to refrigerated storage.

Instructions for use and handling – Reconstitution, dilution and administration
To improve traceability of biological medicinal products, the trade name and batch number of the administered product should be clearly documented.

  1. Calculate the required dose and number of Zessly vials needed. Each Zessly vial contains 100 mg of infliximab. Calculate the total volume of reconstituted Zessly solution required.
  2. Under aseptic conditions, reconstitute each Zessly vial with 10 ml of Water for Injections using a syringe fitted with a 21 gauge (0.8 mm) or smaller needle. Remove the aluminium cap and disinfect the rubber stopper with a cotton swab soaked in 70% alcohol. Insert the needle through the center of the rubber stopper and direct the stream of Water for Injections against the glass wall of the vial. Gently swirl the solution to completely dissolve the lyophilized powder. Do not shake vigorously or for prolonged periods. DO NOT SHAKE. Foam may form during reconstitution. Allow the reconstituted solution to stand for 5 minutes. Check that the solution is colourless to brown and opalescent; the solution may contain a few small translucent particles, as infliximab is a protein. Do not use the solution if opaque particles, discoloration or foreign matter are observed.
  3. Dilute the total volume of the reconstituted Zessly solution to 250 ml using a 9 mg/ml (0.9%) sodium chloride solution for injection. Do not dilute the reconstituted Zessly solution with any other diluent. The dilution may be performed by withdrawing from the glass vial or the 250 ml infusion bag a volume of 9 mg/ml (0.9%) sodium chloride solution for injection equal to the volume of reconstituted Zessly. Slowly add the total volume of reconstituted Zessly solution to the vial or 250 ml infusion bag. Mix gently.
  4. Administer the infusion solution over a period not shorter than the recommended infusion time. Use only an infusion set with an in-line sterile, non-pyrogenic filter with low protein binding capacity (pore size 1.2 micrometres or less). As no preservative is present, administration of the intravenous infusion solution should begin as soon as possible and within 3 hours of reconstitution and dilution. If reconstitution and dilution are performed under aseptic conditions, the Zessly infusion solution may be used within 24 hours if stored at 2 °C – 8 °C. Any unused solution must not be stored for later use.
  5. No physical and biochemical compatibility studies have been conducted to evaluate the co-administration of Zessly with other agents. Do not administer Zessly concomitantly with other medicinal products in the same intravenous line.
  6. Before administration, visually inspect Zessly for the presence of particles or discoloration. If opaque particles, discoloration or foreign particles are observed, do not use the solution.
  7. Any unused medicinal product and waste material derived from this medicinal product must be disposed of in accordance with local regulations.
