Introduction
Recombinant human IgG1 kappa monoclonal antibody that binds specifically to interleukin-17A (IL-17A).
Uses for Secukinumab
Plaque Psoriasis
Management of moderate to severe plaque psoriasis in adults and pediatric patients ≥6 years of age who are candidates for phototherapy or systemic therapy.
Adult guidelines generally support the use of IL-17 inhibitors as monotherapy for treatment of moderate to severe psoriasis.
Pediatric guidelines have not yet incorporated recommendations for use of IL-17 blocking agents for the treatment of pediatric plaque psoriasis.
Recommendations for use and selection of psoriasis therapies vary based on patient age, disease characteristics (e.g., severity, location, presence of psoriatic arthritis), and comorbidities (e.g., inflammatory bowel disease).
Psoriatic Arthritis
Management of active psoriatic arthritis in adults.
Disease-modifying treatments for psoriatic arthritis include oral small molecules (OSMs; e.g., methotrexate, sulfasalazine, cyclosporine, leflunomide, apremilast), biologic DMARDs (e.g., TNF blocking agents, secukinumab, ixekizumab, ustekinumab, brodalumab, abatacept), and/or targeted synthetic DMARDs (e.g., tofacitinib).
Guidelines generally support the use of IL-17 blocking agents, including secukinumab, as second-line therapy after TNF inhibitors for treatment of psoriatic arthritis.
Recommendations for the use and selection of disease-modifying therapies in psoriatic arthritis vary based on the presence of certain disease characteristics (e.g., psoriatic spondylitis/axial disease, enthesitis) and comorbidities (e.g., inflammatory bowel disease, diabetes).
Ankylosing Spondylitis
Management of active ankylosing spondylitis in adults.
Treatments for ankylosing spondylitis include NSAIAs, conventional DMARDs (e.g., methotrexate, sulfasalazine), biologic DMARDs (e.g., TNF blocking agents, secukinumab, ixekizumab), and/or targeted synthetic DMARDs (e.g., tofacitinib).
Guidelines generally support the use of IL-17 inhibitors, including secukinumab, as second-line therapy after TNF blocking agents for the treatment of ankylosing spondylitis in patients with active disease despite treatment with NSAIAs.
Recommendations for treatment selection in ankylosing spondylitis vary based on the presence of certain comorbidities (e.g., iritis, inflammatory bowel disease).
Nonradiographic Axial Spondyloarthritis
Management of active nonradiographic axial spondyloarthritis in adults with objective signs of inflammation.
Recommendations for the treatment of nonradiographic axial spondyloarthritis are largely extrapolated from evidence in the treatment of ankylosing spondylitis. Guidelines generally support the use of IL-17 inhibitors, including secukinumab, as second-line therapy after TNF blocking agents in patients with active disease despite treatment with NSAIAs.
Secukinumab Dosage and Administration
General
Pretreatment Screening
-
Evaluate for tuberculosis infection prior to initiating therapy; start antimycobacterial therapy if indicated.
-
Administer all age-appropriate vaccines prior to starting therapy.
Patient Monitoring
-
Monitor closely for signs or symptoms of infection or active tuberculosis during and after treatment with secukinumab.
-
Monitor for signs and symptoms of inflammatory bowel disease during treatment.
Other General Considerations
-
Secukinumab may be used alone or in combination with methotrexate for the treatment of psoriatic arthritis.
Administration
Administer by sub-Q injection; IV use not recommended by manufacturer.
Sub-Q Administration
Available as injection pen, prefilled syringe, and lyophilized drug in vial. Lyophilized drug intended for institutional use only.
Administer by sub-Q injection into the upper arms, thighs, or any quadrant of the abdomen; do not make abdominal injections within 2 inches of the navel. Rotate injection sites. Do not make injections into areas where the skin is tender, bruised, erythematous, indurated, or affected by psoriasis.
Intended for use under the guidance and supervision of a clinician, but may be self-administered if clinician determines the patient and/or their caregiver is competent to safely administer the drug after appropriate training. Pediatric patients are not eligible for self-administration; however, an adult caregiver can administer to pediatric patients after proper training.
Use of injection pen may result in higher trough concentrations.
Use of Injection Pen or Prefilled Syringe
Remove injection pen or prefilled syringe from refrigerator and allow to sit at room temperature in the unopened carton for 15–30 minutes prior to injection. Do not remove needle cap while pen or prefilled syringe is warming to room temperature. Administer within 1 hour after removal from refrigerator.
Do not shake the solution.
Discard any unused portions of solution.
Reconstitution of Lyophilized Secukinumab
Reconstitution of secukinumab lyophilized powder must proceed without interruption. Preparation time from vial puncture until end of reconstitution on average is 20 minutes; do not exceed 90 minutes.
Remove the appropriate number of vials containing secukinumab lyophilized powder from refrigerator and allow drug to sit for 15–30 minutes to reach room temperature prior to reconstitution.
Reconstitute drug by slowly adding 1 mL of sterile water for injection (also at room temperature) to a vial containing 150 mg of secukinumab to provide a solution containing 150 mg/mL; direct stream of diluent onto the lyophilized powder.
Tilt vial at an angle of approximately 45 degrees and gently rotate between the fingertips for approximately 1 minute; do not shake or invert vial. Allow vial to sit for approximately 10 minutes at room temperature to allow for dissolution; foaming may occur.
Tilt vial again at an angle of approximately 45 degrees and gently rotate between the fingertips for approximately 1 minute; do not shake or invert vial. Allow vial to sit undisturbed for approximately 5 minutes at room temperature.
Administer solution immediately following reconstitution or refrigerate for up to 24 hours. If stored in refrigerator, allow solution to sit for 15–30 minutes to reach room temperature prior to administration; administer within 1 hour following removal from refrigerator.
Do not invert vial when withdrawing solution for administration.
Discard any unused portions of solution.

Cautions for Secukinumab
Contraindications
-
Known hypersensitivity to secukinumab or any ingredient in the formulation.
Warnings/Precautions
Sensitivity Reactions
Hypersensitivity Reactions
Anaphylaxis and urticaria reported. (See Contraindications under Cautions.) If an anaphylactic or other serious allergic reaction occurs, discontinue drug immediately and administer appropriate supportive treatment.
Latex Sensitivity
Some packaging components (i.e., removable cap) of injection pen and prefilled syringe contain natural rubber latex and should not be handled by individuals sensitive to latex.
Some individuals may be hypersensitive to natural latex proteins; rarely, hypersensitivity reactions to natural latex proteins have been fatal.
Manufacturer states safety of using secukinumab injection pen or prefilled syringe in latex-sensitive individuals not established.
Infectious Complications
Increased risk of infections. Higher rates of common infections (e.g., nasopharyngitis, upper respiratory tract infection, mucocutaneous candidiasis) observed in patients receiving secukinumab compared with those receiving placebo. Serious and some fatal infections also reported. Incidence of some types of infections appeared to be dose dependent.
Secukinumab-associated neutropenia, generally transient and reversible, reported; no serious neutropenia-associated infections reported in the controlled portion of clinical trials. Some cases of serious infections were associated with neutropenia in open-label extensions of clinical trials, but a causal relationship was not established.
Exercise caution when considering use in patients with chronic or recurrent infections.
If a serious infection develops, monitor patient closely and discontinue drug until infection resolves.
Evaluate patients for tuberculosis before initiating secukinumab. Do not administer to patients with active tuberculosis infection. When indicated, initiate appropriate antimycobacterial regimen for treatment of latent tuberculosis infection before initiating secukinumab. Also consider antimycobacterial therapy for patients with a history of latent or active tuberculosis in whom an adequate course of antimycobacterial treatment cannot be confirmed. Closely monitor patients for active tuberculosis during and after secukinumab treatment.
Inflammatory Bowel Disease
Use with caution and close monitoring in patients with coexisting inflammatory bowel disease. Exacerbations of such disease reported, some of which were serious. Cases of new-onset inflammatory bowel disease also reported.
Immunization
Consider administering all age-appropriate vaccines recommended by current immunization guidelines before initiating secukinumab.
Avoid live vaccines during therapy. Patients may receive inactivated vaccines.
Immunogenicity
Formation of antisecukinumab antibodies, including neutralizing antibodies, reported; neutralizing antibodies were not associated with loss of efficacy.
Specific Populations
Pregnancy
Reproductive and developmental toxicity studies in monkeys revealed no evidence of adverse developmental effects on fetuses or neonatal offspring. Data regarding secukinumab use in pregnant women are insufficient to inform a drug-associated risk.
Lactation
Not known whether secukinumab is distributed into human milk or absorbed systemically after ingestion. Use caution.
Potential effects on milk production or on breast-fed infants are unknown. Consider benefits of breast-feeding and the importance of secukinumab to the woman as well as potential adverse effects on the breast-fed infant from the drug or underlying maternal condition.
Pediatric Use
Safety and efficacy not established in pediatric patients <6 years of age for plaque psoriasis and in pediatric patients <18 years of age for all other indications.
Geriatric Use
No apparent differences in safety or efficacy between geriatric patients and younger adults with plaque psoriasis; however, insufficient experience in patients ≥65 years of age to determine whether they respond differently than younger adults.
Hepatic Impairment
No formal pharmacokinetic studies to date.
Renal Impairment
No formal pharmacokinetic studies to date.
Common Adverse Effects
Adverse effects reported in ≥1% of patients receiving secukinumab include nasopharyngitis, diarrhea, and upper respiratory tract infection.
Drug Interactions
Drugs Metabolized by Hepatic Microsomal Enzymes
Manufacturer states role of IL-17A in the regulation of CYP isoenzymes not elucidated. Because elevated levels of certain cytokines during chronic inflammation may alter formation of CYP isoenzymes, antagonism of IL-17A activity by secukinumab could normalize formation of CYP enzymes.
CYP substrates: Upon initiation or discontinuance of secukinumab, consider monitoring for therapeutic effect or drug concentration and consider dosage adjustment of the CYP substrate, especially if substrate has a narrow therapeutic index.
Vaccines
Inactivated vaccines: Patients may receive inactivated vaccines.
Live vaccines: Avoid live vaccines.

Secukinumab Pharmacokinetics
Absorption
Bioavailability
Bioavailability is 55–77% following sub-Q administration.
Peak serum concentrations achieved by approximately 6 days following sub-Q administration of secukinumab 150 or 300 mg.
Steady-state concentrations achieved by week 24 following sub-Q administration of secukinumab every 4 weeks.
Cross-study comparisons suggest that administration by injection pen may result in higher trough concentrations (23–26% higher compared with prefilled syringe or 23–30% higher compared with sub-Q injection of reconstituted powder).
Concentrations in interstitial fluid in lesional and nonlesional skin of patients with plaque psoriasis were 27–40% of those in serum at 1 and 2 weeks after a single 300-mg sub-Q dose.
Pharmacokinetics are dose proportional over a sub-Q dose range of 25–300 mg.
Special Populations
Serum concentrations higher in patients with lower body weight than in those with higher body weight.
Distribution
Extent
Not known whether distributed into human milk.
Special Populations
Volume of distribution increases as body weight increases.
Elimination
Metabolism
Metabolic pathway not characterized.
Expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG.
Half-life
22–31 days.
Special Populations
Pharmacokinetics not formally studied in renal or hepatic impairment.
Population analysis suggests age does not substantially affect clearance in adults with plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis. Clearance appears to be similar in patients ≥65 years of age and younger adults.
Clearance increases as body weight increases.
Stability
Storage
Parenteral
Injection
Injection pen or prefilled syringe: 2–8°C. Keep in original carton and protect from light. Do not freeze. May store at room temperature (not to exceed 30°C) for up to 4 days; discard if stored outside of refrigeration for more than 4 days.
Powder for Injection
