Ocular disorders, including allergic conjunctivitis, conjunctivitis, keratoconjunctivitis, atopic keratoconjunctivitis, keratitis, and ulcerative keratitis have been reported. In clinical trials, most cases were mild or moderate and resolution occurred in ~75% of cases despite continued treatment with tralokinumab (Ref).
Mechanism: Unknown; tralokinumab inhibits IL-13 signaling, which may lead to decreased intraepithelial conjunctival goblet cells and lower mucus production (Ref).
Onset: Delayed; median time to first episode of conjunctivitis in clinical trials: 50 days (Ref).
Risk factors:
• Severe atopic dermatitis at baseline (Ref)
• History of allergic conjunctivitis/atopic keratoconjunctivitis (Ref)
• Number of atopic comorbidities (ie, asthma, food allergy, hay fever) (Ref)

Frequency not defined:
Hypersensitivity: Hypersensitivity reaction (including anaphylaxis and angioedema)
Immunologic: Antibody development
Postmarketing: Dermatologic: Psoriasis (Balakirski 2023)
Hypersensitivity to tralokinumab or any component of the formulation.
Concerns related to adverse effects:
• Hypersensitivity reactions: Hypersensitivity reactions, including anaphylaxis and angioedema, have been reported. If signs/symptoms of a serious hypersensitivity reaction develop, discontinue use immediately and initiate appropriate treatment.
• Ocular effects: Conjunctivitis and keratitis have been reported; advise patients to report any new-onset or worsening eye symptoms.
Disease-related concerns:
• Helminth infections: It is unknown if administration of tralokinumab will influence a patient's response against parasitic infections; patients with known helminth infections were not studied. Treat any preexisting helminth infections prior to initiating tralokinumab. In patients who become infected during treatment and do not respond to antihelminth therapy, discontinue tralokinumab until the infection resolves.
Dosage form specific issues:
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson, 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer's labeling.
Other warnings/precautions:
• Immunizations: Complete all age-appropriate immunizations before initiating therapy; avoid administering live vaccines during therapy. Limited data regarding coadministration with nonlive vaccines suggest similar antibody responses in tralokinumab-treated and placebo-treated patients.
• Immunogenicity: Tralokinumab antibodies, including neutralizing antibodies, may develop.

Solution Prefilled Syringe, Subcutaneous:
Adtralza: Tralokinumab-ldrm 150 mg/mL (1 mL) [contains polysorbate 80]
SUBQ: Determine the number of prefilled syringe(s) needed for dose; each syringe contains 150 mg. Remove prefilled syringe(s) required for the dose from the refrigerator and allow to reach room temperature for 30 minutes prior to use; do not heat in microwave, hot water, or direct sunlight. Do not shake syringes. Solution should be clear to opalescent, colorless to pale yellow; do not use if cloudy, discolored, or contains particulate matter or syringe appears damaged. Do not remove needle cover until immediately prior to injection. Administer SUBQ into the thigh or lower abdomen, avoiding areas within 2 inches of navel; caregiver may administer in upper arm. Do not administer into skin that is tender, damaged, bruised, or scarred. If the dose requires more than one injection, ensure each injection is at least 1 inch from the prior injection site and within the same body area; rotate body areas with each subsequent set of injections. Prefilled syringes do not contain preservatives; discard any unused product remaining in the prefilled syringe.
Missed doses: Administer missed dose as soon as possible. Thereafter, resume dosing at the regular scheduled time.
SUBQ: Allow prefilled syringe to reach room temperature for 30 minutes prior to use; do not heat prefilled pen in microwave, hot water, or direct sunlight. Do not shake syringes. Do not remove needle cover until immediately prior to injection. Administer SUBQ into the thigh or lower abdomen, avoiding areas within 2 inches of navel; caregiver may administer in upper arm. Administer the 600 mg dose as a set of four 150 mg injections and the 300 mg dose as a set of two 150 mg injections. For each set of injections, ensure each injection is at least 1 inch (3 cm) from the prior injection site and within the same body area; rotate body areas with each subsequent set of injections. Prefilled syringe does not contain preservatives; discard any unused product remaining in the prefilled syringe. May use with topical corticosteroids and topical calcineurin inhibitors; reserve concurrent use of topical calcineurin inhibitors to problem areas of the face, genital, intertriginous, and neck areas.
Store refrigerated at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light. If necessary, prefilled syringes may be kept at room temperature up to 30°C (86°F) for a maximum of 14 days in the original carton; do not store above 30°C (86°F). If the carton needs to be removed permanently from refrigerator, the date of removal may be recorded on the outer carton in the space provided. After removal from the refrigerator, must be used within 14 days or discarded; do not return room temperature syringes back to the refrigerator. Do not expose the prefilled syringe to heat or direct sunlight. Do not freeze. Do not shake. Does not contain preservatives. Discard any unused product remaining in the prefilled syringe.
Treatment of moderate to severe atopic dermatitis in patients whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable; can be used with or without topical corticosteroids (FDA approved in ages ≥12 years and adults).

Tralokinumab is a humanized monoclonal antibody (IgG4). Human IgG crosses the placenta. Exposure is dependent upon the IgG subclass, maternal serum concentrations, placental integrity, newborn birth weight, and gestational age, generally increasing as pregnancy progresses. The lowest exposure would be expected during the period of organogenesis and the highest during the third trimester (Clements 2020; Palmeira 2012; Pentsuk 2009).
Data collection to monitor pregnancy and infant outcomes following exposure to tralokinumab is ongoing. Health care providers are encouraged to enroll exposed pregnant patients in the MotherToBaby Pregnancy Studies conducted by the Organization of Teratology Information Specialists (877-311-8972 or https://mothertobaby.org/studies). Patients may also enroll themselves.
Monitor for signs/symptoms of hypersensitivity reactions and ocular adverse effects (conjunctivitis, keratitis) and signs of infection (particularly parasitic [helminth] infections).
Tralokinumab is a human IgG4 monoclonal antibody that binds to interleukin-13 (IL-13) and blocks its interaction with the IL-13 receptor α1 and α2 subunits. Tralokinumab inhibits the bioactivity of IL-13 (a naturally occurring cytokine of the Type 2 immune response), and prevents the release of proinflammatory cytokines, chemokines, and IgE.
Distribution: Vd: ~4.2 L.
Metabolism: Metabolized into small peptides by catabolic pathways.
Bioavailability: ~76%.
Half-life elimination: 3 weeks.
Time to peak: 5 to 8 days.
Excretion: Clearance: 0.149 L/day.
Body weight: Tralokinumab exposure decreases with increasing body weight. At a dosage of 300 mg every 4 weeks, the median AUC of patients weighing >100 kg is expected to be 1.46 times lower than patients weighing <100 kg.
