Adtralza 150 mg solution for injection in pre-filled syringe
⚠ This medicine appears to have been discontinued
The electronic medicines compendium (emc) no longer publishes a Summary of Product Characteristics for this product, which usually means it is no longer marketed in the UK. The patient leaflet below is kept for reference, but the product may not be available.
If you were prescribed this medicine, other products containing Tralokinumab may still be available. Do not stop your treatment — ask your pharmacist or GP what to use instead.
What it is and what it is used for
for
Adtralza contains the active substance tralokinumab. Tralokinumab is a monoclonal antibody (a type of protein) that blocks the action of a protein called IL-13. IL-13 plays a major role in causing the symptoms of atopic dermatitis. Adtralza is used to treat adult and adolescent patients 12 years and older with moderate-to-severe atopic dermatitis, also known as atopic eczema. Adtralza may be used with eczema medicines that you apply to the skin or it may be used on its own. Using Adtralza for atopic dermatitis can improve your eczema and reduce the related itching and skin pain. 2.
What you need to know before you take it

Do not use Adtralza: if you are allergic to tralokinumab or any of the other ingredients of this medicine (listed in section 6). If you think you may be allergic, or you are not sure, ask your doctor, pharmacist or nurse for advice before using Adtralza. Warnings and precautions Talk to your doctor, pharmacist or nurse before using Adtralza. Allergic reactions Very rarely, medicines can cause allergic (hypersensitivity) reactions and severe allergic reactions called anaphylaxis. You must look out for signs of these reactions (such as breathing problems, swelling of the face, mouth, and tongue, fainting, dizziness, feeling lightheaded (because of low blood pressure), hives, itching and skin rash) while you are using Adtralza. Stop using Adtralza and tell your doctor or get medical help immediately if you notice any signs of an allergic reaction. Such signs are listed in the beginning of section 4. 1
Parasitic infection in the intestines Adtralza may reduce your resistance to infections caused by parasites. Any parasitic infection should be treated before you start treatment with Adtralza. Tell your doctor if you have diarrhoea, gas, upset stomach, greasy stools, and dehydration which could be signs of a parasitic infection. If you live in a region where these infections are common or if you are travelling to such a region, tell your doctor. Eye problems Talk to your doctor if you have any new or worsening eye problems, including eye pain or changes in vision. Children Do not give this medicine to children below the age of 12 years because the safety and benefits of Adtralza are not yet known in this population. Other medicines and Adtralza Tell your doctor or pharmacist If you are using, have recently used or might use any other medicines. If you have recently had a vaccination or are due to have one. Pregnancy and breast-feeding If you are pregnant or breast-feeding, think you may be pregnant or you are planning to have a baby, ask your doctor for advice before using this medicine. The effects of Adtralza in pregnant women are not known; therefore, it is preferable to avoid using it during pregnancy unless your doctor advises you to use it. If applicable, you and your doctor should decide if you will breast-feed or use Adtralza. You should not do both. Driving and using machines Adtralza is unlikely to reduce your ability to drive and use machines. Adtralza contains sodium This medicine contains less than 1 mmol sodium (23 mg) per 150 mg that is to say essentially "sodium-free". Adtralza contains polysorbate (E 433) This medicine contains 0.1 mg of polysorbate 80 in each pre-filled syringe which is equivalent to 0.1 mg/ml. Polysorbates may cause allergic reactions. Tell your doctor if you have known allergies. 3.

Step 2: Choosing and preparing injection area
Injection by caregiver only Self-injection or injection by caregiver
2a: Choose the area for your injections You may inject into: • o your stomach area (abdomen) o your thighs o your upper arm. To inject into your upper arm, you will need a caregiver to give you the injections. Do not inject where the skin is tender, bruised, scaly, scarred, damaged, hard or covered with • eczema. Do not inject within 5 cm of your belly button (navel). •
2b: Wash your hands and prepare your skin Wash your hands with soap and water. • Clean the injection area for the 2 injections with an alcohol swab using a circular motion. • o Let the area dry completely. o Do not blow on or touch the cleaned area before injecting. Step 3: Injecting Adtralza
3a: Pull off the Adtralza needle cover Hold the Adtralza pre-filled syringe body with one hand, pull the needle cover straight off with your other hand and throw it into the puncture-resistant container. Do not try to recap the Adtralza pre-filled syringes. • Do not hold the plunger rod or plunger head while removing the needle cover. • 9

⚕For healthcare professionals — Summary of Product Characteristics (SmPC)Full SmPC: dosage, interactions, contraindications, warnings+
4.1. Therapeutic indications
Adtralza is indicated for the treatment of moderate‑to‑severe atopic dermatitis in adult and adolescent patients 12 years and older who are candidates for systemic therapy.
4.2. Posology and method of administration
Treatment should be initiated by healthcare professionals experienced in the diagnosis and treatment of atopic dermatitis.
Posology
The recommended dose of tralokinumab for adult and adolescent patients 12 years and older is an initial dose of 600 mg administered as four 150 mg injections given by pre-filled syringes.
This initial dose is followed by a 300 mg injection administered every other week as two 150 mg injections given by pre-filled syringes.
At prescriber's discretion, every fourth week dosing may be considered for patients who achieve clear or almost clear skin after 16 weeks of treatment. The probability of maintaining clear or almost clear skin may be lower with every fourth week dosing (see section 5.1).
Consideration should be given to discontinuing treatment in patients who have shown no response after 16 weeks of treatment. Some patients with initial partial response may subsequently improve further with continued treatment every other week beyond 16 weeks.
Tralokinumab can be used with or without topical corticosteroids. The use of topical corticosteroids, when appropriate, may provide an additional effect to the overall efficacy of tralokinumab (see section 5.1). Topical calcineurin inhibitors may be used, but should be reserved for problem areas only, such as the face, neck, intertriginous and genital areas.
Missed dose
If a dose is missed, the dose should be administered as soon as possible. Thereafter, dosing should be resumed at the regular scheduled time.
Special populations
Elderly
No dose adjustment is recommended for elderly patients (see section 5.2). Limited data are available in patients > 75 years of age.
Renal impairment
No dose adjustment is needed in patients with renal impairment. Very limited data are available in patients with severe renal impairment (see section 5.2).
Hepatic impairment
No dose adjustment is needed in patients with hepatic impairment. Very limited data are available in patients with moderate or severe hepatic impairment (see section 5.2).
High body weight
For patients with high body weight (> 100 kg), who achieve clear or almost clear skin after 16 weeks of treatment, reducing the dose to every fourth week might not be appropriate (see section 5.2).
Paediatric population
The safety and efficacy of tralokinumab in children below the age of 12 years have not yet been established. No data are available.
Method of administration
For subcutaneous use.
The pre-filled syringe should not be shaken. After removing the pre‑filled syringes from the refrigerator, they should be allowed to reach room temperature by waiting for 30 minutes before injecting the pre-filled syringe.
Tralokinumab is administered by subcutaneous injection into the thigh or abdomen, except the 5 cm around the navel. If somebody else administers the injection, the upper arm can also be used.
For the initial 600 mg dose, four 150 mg pre-filled syringes should be administered consecutively in different injection sites within the same body area.
It is recommended to rotate the injection site with each dose. Tralokinumab should not be injected into skin that is tender, damaged or has bruises or scars.
A patient may self‑inject tralokinumab or the patient's caregiver may administer tralokinumab if their healthcare professional determines that this is appropriate. Proper training should be provided to patients and/or caregivers on the administration of tralokinumab prior to use. Detailed instructions for use are included at the end of the package leaflet.
4.3. Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
4.4. Special warnings and precautions for use
Traceability
In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.
Hypersensitivity
If a systemic hypersensitivity reaction (immediate or delayed) occurs, administration of tralokinumab should be discontinued and appropriate therapy initiated.
Conjunctivitis
Patients treated with tralokinumab who develop conjunctivitis that does not resolve following standard treatment should undergo ophthalmological examination (see section 4.8).
Helminth infection
Patients with known helminth infections were excluded from participation in clinical studies. It is unknown if tralokinumab will influence the immune response against helminth infections by inhibiting IL‑13 signalling.
Patients with pre‑existing helminth infections should be treated before initiating treatment with tralokinumab. If patients become infected while receiving tralokinumab and do not respond to antihelminth treatment, treatment with tralokinumab should be discontinued until infection resolves.
Vaccinations
Live and live attenuated vaccines should not be given concurrently with tralokinumab as clinical safety and efficacy have not been established. Immune responses to the non‑live tetanus and meningococcal vaccines were assessed (see section 4.5). It is recommended that patients should be brought up to date with live and live attenuated immunisations in agreement with current immunisation guidelines prior to treatment with tralokinumab.
Excipients
Sodium
This medicinal product contains less than 1 mmol sodium (23 mg) per 150 mg dose, that is to say essentially “sodium‑free”.
Adverse reactions to excipients
Adtralza contains polysorbate 80 (E 433) as an excipient, which may cause allergic reactions.
4.5. Interaction with other medicinal products and other forms of interaction
The safety and efficacy of concurrent use of tralokinumab with live and live attenuated vaccines has not been studied.
Immune responses to non‑live vaccines were assessed in a study in which adult patients with atopic dermatitis were treated with an initial dose of 600 mg (four 150 mg injections) followed by 300 mg every second (other) week administered as subcutaneous injection. After 12 weeks of tralokinumab administration, patients were vaccinated with a combined tetanus, diphtheria, and acellular pertussis vaccine, and a meningococcal vaccine and immune responses were assessed 4 weeks later. Antibody responses to both tetanus vaccine and meningococcal vaccine were similar in tralokinumab‑treated and placebo‑treated patients. No adverse interactions between either of the non‑live vaccines or tralokinumab were noted in the study. Therefore, patients receiving tralokinumab may receive concurrent inactivated or non‑live vaccinations.
For information on live and live attenuated vaccines, see section 4.4.
Interactions with cytochrome P450
Tralokinumab is not expected to undergo metabolism by hepatic enzymes or renal elimination. Clinically relevant interactions between tralokinumab and inhibitors, inducers, or substrates of metabolising enzymes are not expected, and no dose adjustment is needed.
The effects of tralokinumab on the pharmacokinetics (PK) of CYP substrates, caffeine (CYP1A2), warfarin (CYP2C9), metoprolol (CYP2D6), omeprazole (CYP2C19) and midazolam (CYP3A), were evaluated in atopic dermatitis patients after repeated administration. No effects were observed for caffeine and warfarin. Small numerical changes, which were not clinically significant, were observed for Cmax of omeprazole, AUC of metoprolol and AUC and Cmax of midazolam (the largest difference being for midazolam Cmax with a decrease of 22%). Therefore, clinically relevant impact of tralokinumab on the pharmacokinetics of concomitant medicinal products metabolised by the CYP enzymes is not expected.
4.6. Fertility, pregnancy and lactation
Pregnancy
There is limited amount of data from the use of tralokinumab in pregnant women.
Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity (see section 5.3).
As a precautionary measure, it is preferable to avoid the use of tralokinumab during pregnancy.
Breast‑feeding
It is unknown whether tralokinumab is excreted in human milk or absorbed systemically after ingestion. A decision must be made whether to discontinue breast‑feeding or to discontinue tralokinumab therapy taking into account the benefit of breast‑feeding for the child and the benefit of therapy for the woman.
Fertility
Animal studies did not show any effects on male and female reproductive organs and on sperm count, motility and morphology (see section 5.3).
4.7. Effects on ability to drive and use machines
Tralokinumab has no or negligible influence on the ability to drive and use machines.
4.8. Undesirable effects
Summary of the safety profile
The most common adverse reactions are upper respiratory tract infections (23.4%; mainly reported as common cold), injection site reactions (7.2%), conjunctivitis (5.4%) and conjunctivitis allergic (2.0%).
Tabulated list of adverse reactions
Adverse reactions observed from clinical trials and post-marketing experience are presented in Table 1 by system organ class and frequency, using the following categories: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1 000 to < 1/100); rare (≥ 1/10 000 to < 1/1 000); very rare (< 1/10 000). Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness. The frequencies are based on the initial treatment period of up to 16 weeks in the pool of 5 studies in the atopic dermatitis population.

Injection site reactions
The long‑term safety of tralokinumab was assessed in 2 monotherapy studies up to 52 weeks, and in a combination study with topical corticosteroids up to 32 weeks. The long-term safety of tralokinumab is further assessed in an open-label extension study (ECZTEND) for up to 5 years of treatment in adults and up to 2 years in adolescents 12 years and older with moderate-to-severe AD (atopic dermatitis) receiving 300 mg of tralokinumab every two weeks (Q2W). The long-term safety data were generally consistent with the safety profile observed up to week 16 in the pool of 5 adult studies.
Description of selected adverse reactions
Conjunctivitis and related events
Conjunctivitis occurred more frequently in atopic dermatitis patients who received tralokinumab (5.4%) compared to placebo (1.9%) in the initial treatment period of up to 16 weeks in the pool of 5 studies. Conjunctivitis was reported at a higher frequency in patients with severe atopic dermatitis compared to subjects with moderate atopic dermatitis in both the tralokinumab group (6.0 vs 3.3%; initial treatment period) and placebo group (2.2 vs 0.8%; initial treatment period). Most patients recovered or were recovering during the treatment period.
The rate of conjunctivitis in the initial 16 weeks treatment period was 22.0 events/100 patient years of exposure. The rate of conjunctivitis in the treatment period of the long-term open-label extension study (ECZTEND) was 2.93 events/100 patient years of exposure.
Keratitis was reported in 0.5% of subjects treated with tralokinumab during the initial treatment period. Of these, half were classified as keratoconjunctivitis, all were non‑serious and mild or moderate in severity, and none led to treatment discontinuation.
The rate of keratitis in the initial 16 weeks treatment period was 1.7 events/100 patient years of exposure. The rate of keratitis in the treatment period of the long-term open-label extension study (ECZTEND) was 0.11 events/100 patient years of exposure.
Eosinophilia
Adverse reactions of eosinophilia were reported in 1.3% of patients treated with tralokinumab and 0.3% of patients treated with placebo during the initial treatment period of up to 16 weeks in the pool of 5 studies. Tralokinumab‑treated patients had a greater mean initial increase from baseline in eosinophil count compared to patients treated with placebo. Eosinophilia (≥ 5 000 cells/mcL) was measured in 1.2% of tralokinumab‑treated patients and 0.3% of placebo‑treated patients in the initial treatment period. However, the increase in the tralokinumab‑treated patients was transient, and mean eosinophil counts returned to baseline during continued treatment. The safety profile for subjects with eosinophilia was comparable to the safety profile for all subjects.
Eczema herpeticum
Eczema herpeticum was reported in 0.3% of the subjects treated with tralokinumab and in 1.5% of subjects in the placebo group in the initial treatment period of up to 16 weeks in the pool of 5 studies in atopic dermatitis. The rate of eczema herpeticum in the initial 16 weeks treatment period was 1.2 events/100 patient years of exposure. The rate of eczema herpeticum in the treatment period of the long-term open-label extension study (ECZTEND) was 0.67 events/100 patient years of exposure.
Immunogenicity
As with all therapeutic proteins, there is a potential for immunogenicity with tralokinumab.
Anti‑drug‑antibody (ADA) responses were not associated with any impact on tralokinumab exposure, safety, or efficacy in patients receiving tralokinumab for up to 6 years (in phase 2/phase 3 atopic dermatitis studies followed by the long-term extension study ECZTEND).
No immunogenicity-related adverse events such as immune-complex disease, serum sickness/serum sickness-like reactions, or anaphylaxis were observed.
In ECZTRA 1, ECZTRA 2, ECZTRA 3, and the vaccine‑response study, the incidence of ADA up to 16 weeks was 1.4% in patients treated with tralokinumab and 1.3% in patients treated with placebo; neutralising antibodies were seen in 0.1% of patients treated with tralokinumab and 0.2% of patients treated with placebo.
The ADA incidence in patients who received tralokinumab up to 52 weeks was 4.6%; 0.9% had persistent ADA and 1.0% had neutralising antibodies.
ADA incidences in patients who received tralokinumab for up to 6 years (in phase 2/phase 3 atopic dermatitis studies followed by the long-term extension study ECZTEND) were similar to those observed after 52 weeks in ECZTRA 1 and 2.

Injection site reactions (including pain and redness) occurred more frequently in patients who received tralokinumab (7.2%) compared to placebo (3.0%) in the initial treatment period of up to 16 weeks in the pool of 5 studies. Across all treatment periods in the 5 studies in atopic dermatitis, the vast majority (99%) of injection site reactions were mild or moderate in severity, and few patients (< 1%) discontinued tralokinumab treatment. Most injections site reactions reported had a short duration with approximately 76% of the events resolving within 1 to 5 days.
The rate of injection site reactions in the initial 16 weeks treatment period was 51.5 events/100 patient years of exposure. The rate of injection site reactions in the treatment period of the long-term open-label extension study (ECZTEND) was 5.89 events/100 patient years of exposure.
Paediatric population
The safety of tralokinumab was assessed in patients 12 to 17 years of age (adolescents) with moderate‑to‑severe atopic dermatitis in a monotherapy study of 289 adolescents (ECZTRA 6) and in a long-term open-label extension study (ECZTEND) including 127 adolescents transferred from ECZTRA 6. The safety profile of tralokinumab in these patients followed through the initial treatment period of 16 weeks and maintenance treatment period of 52 weeks in ECZTRA 6, as well as in the long-term treatment period of up to 2 years in ECZTEND, was overall similar to the safety profile from studies in adults. In the initial treatment period of 16 weeks, however, conjunctivitis was reported at lower frequency with tralokinumab in adolescents (1.0% in ECZTRA 6) than in adults (5.4% in the pool of 5 studies), and, unlike in adults, the frequency of conjunctivitis allergic was similar for tralokinumab and placebo in adolescent patients.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
4.9. Overdose
There is no specific treatment for tralokinumab overdose. In clinical studies with tralokinumab, single intravenous doses of up to 30 mg/kg and multiple subcutaneous doses of 600 mg every 2 weeks for 12 weeks were found to be well tolerated.
