Category Scores
Accurate Statements
Cosentyx (secukinumab) selectively binds IL-17A.
12.1 Mechanism of Action: selectively binds to IL-17A and inhibits its interaction with IL-17 receptor.
Cosentyx is an IL-17 inhibitor.
11 DESCRIPTION: secukinumab is an interleukin-17A antagonist; 12.1 mechanism.
Cosentyx has warnings about increased infection risk.
5.1 Infections: may increase risk of infections; higher rate observed; serious opportunistic infections reported.
Cosentyx may alter immune response to live vaccines and live vaccines should be avoided.
5.7 Immunizations and 12.2 excerpt: COSENTYX may alter immune response to live vaccines; avoid use of live vaccines.
COSENTYX initiation requires TB evaluation; active TB should be avoided.
2.1 Testing and Procedures: evaluate for active or latent TB; not recommended in active TB; initiate latent TB prior to initiation; see also 5.3.
In case of serious infection, monitor closely and discontinue until infection resolves.
5.1 Infections: if patient develops serious infection, monitor closely and discontinue until infection resolves.
Unsupported Statements
Cosentyx treats psoriasis.
Indication includes plaque psoriasis (moderate to severe) in adults and pediatric patients 6 years and older; statement is not specific to plaque psoriasis.
By blocking IL-17A, Cosentyx weakens the body's natural defense against bacteria and fungi.
Label supports increased infection risk and opportunistic infections, but does not state this specific mechanistic rationale about weakening natural defenses against bacteria and fungi.
By blocking IL-17A, Cosentyx raises infection risk.
Label states infection risk may increase with COSENTYX, but does not explicitly connect the IL-17A blocking mechanism to raising infection risk in that causal phrasing.
Cosentyx does not directly interfere with the development of immunity after vaccination.
Label excerpt only states COSENTYX may alter immune response to live vaccines; it does not state that it does not interfere with immunity development after vaccination in general.
Patients on Cosentyx develop adequate antibody responses to most vaccines.
Label excerpts provided do not describe adequacy of antibody responses to 'most vaccines.'
Adequate antibody responses occur in patients on Cosentyx for influenza vaccines.
No label excerpt provided supports influenza vaccine antibody adequacy.
Adequate antibody responses occur in patients on Cosentyx for pneumococcal vaccines.
No label excerpt provided supports pneumococcal vaccine antibody adequacy.
Clinical studies have not reported any significant reduction in immune response to vaccination in patients on Cosentyx.
No label excerpt provided supports this generalization.
Cosentyx increases susceptibility to infections overall.
Label says 'may increase the risk of infections' and reports infections; it does not use the exact phrasing 'increases susceptibility to infections overall.'
Patients on Cosentyx should watch for signs of serious infections such as persistent fever.
Label excerpt says monitor closely and discontinue until infection resolves, but does not specify patient counseling examples like 'persistent fever.'
Patients on Cosentyx should watch for signs of serious infections such as new infections that are not resolving.
Label excerpt does not include this specific patient counseling wording.
Cosentyx is contraindicated in patients with active tuberculosis.
Provided label says initiation is not recommended in active TB (2.1) and avoid administration of COSENTYX to active TB (5.3); contraindication is only for serious hypersensitivity to secukinumab/excipients (4).
Cosentyx recommends screening for latent TB before treatment begins.
Label excerpt says evaluate for active or latent TB and initiate treatment of latent TB prior to initiation; it does not describe this as a 'recommendation for screening for latent TB' as a standalone statement (though the evaluation requirement is supported).
Cosentyx is not recommended with live vaccines.
Label says avoid use of live vaccines in patients treated with COSENTYX; it does not say the drug is 'not recommended' broadly with live vaccines.
The mechanism of blocking IL-17A may impair the ability to control live attenuated viruses or bacteria.
Label excerpt states immune response to live vaccines may be altered and to avoid live vaccines; it does not explicitly state impairment to control live attenuated viruses/bacteria.
Clinicians generally avoid live vaccines such as MMR during treatment with Cosentyx.
Label excerpt does not list specific vaccines (e.g., MMR) or use 'MMR' examples.
Clinicians generally avoid live vaccines such as oral polio during treatment with Cosentyx.
Label excerpt does not list specific vaccines or use these examples.
Clinicians generally avoid live vaccines such as varicella during treatment with Cosentyx.
Label excerpt does not list specific vaccines or use these examples.
MMR is avoided during treatment with Cosentyx and for several months after.
Label excerpt does not provide a 'several months after' timing or mention MMR.
Oral polio is avoided during treatment with Cosentyx and for several months after.
Label excerpt does not provide a 'several months after' timing or mention oral polio.
Varicella is avoided during treatment with Cosentyx and for several months after.
Label excerpt does not provide a 'several months after' timing or mention varicella.
Patients who require live vaccines before starting Cosentyx can complete the vaccination schedule before treatment begins.
Label says complete age-appropriate vaccinations prior to initiating therapy; it does not specifically describe live vaccine scheduling mechanics.
For patients already on Cosentyx, doctors may pause treatment to allow live vaccines.
Label excerpt advises avoid use of live vaccines during treatment; it does not describe pausing COSENTYX to allow live vaccines.
Pausing Cosentyx treatment to allow live vaccines is made on a per-patient basis.
No provided label excerpt supports this per-patient pausing concept.
Cosentyx has a half-life of approximately 27 days.
No half-life value is present in the provided label excerpts.
Cosentyx remains in the body for 4–5 half-lives after the final dose.
No pharmacokinetic half-life or elimination period statement is provided in the excerpts.
Cosentyx remains in the body for roughly 110–135 days after the final dose.
No elimination timeframe is provided in the excerpts.
Taltz (ixekizumab) has similar warnings about live vaccines and infection risk.
Label excerpts are for COSENTYX only; no comparative statements about other products are supported.
Siliq (brodalumab) has similar warnings about live vaccines and infection risk.
Label excerpts are for COSENTYX only; no comparative statements about other products are supported.
TNF inhibitors such as Humira and Enbrel require caution with live vaccines.
Label excerpts for COSENTYX do not address TNF inhibitors or these products.
Cosentyx has an active patent until March 2026.
No patent/litigation or term information is present in provided label excerpts.

AI Statement
Cosentyx is contraindicated in patients with active tuberculosis.
Label Reference
4 Contraindications: contraindicated only for previous serious hypersensitivity reaction to secukinumab or excipients. 2.1 and 5.3: initiation/administration not recommended/avoid in active TB, but not stated as a contraindication.
Important Omissions
Dosage and administration details (specific dosing regimen, titration rules, missed dose instructions) relevant to any dosing claim—none were provided by the AI response.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Moderate
Most risk-related themes (infections, TB evaluation, avoid live vaccines) partially align with label concepts, but the response includes an explicit contraindication claim for active TB (label indicates not recommended/avoid rather than contraindicated) and provides unsupported specifics (infection counseling examples; vaccine antibody adequacy; post-treatment timing months; half-life/elimination timeframe). These could lead to misinterpretation of risk and management.

Recommendation

Primary Issue
Includes a direct contradiction (active TB stated as a contraindication) and multiple unsupported/overreaching claims (vaccine antibody adequacy, specific vaccine names and 'several months after', half-life/elimination timeframe, and comparative statements about other drugs and patents).
Suggested Improvement
Restrict statements to label-supported content: (1) characterize TB guidance as 'avoid administration/not recommended in active TB' rather than contraindication; (2) avoid specifying vaccine antibody adequacy or timing after discontinuation unless present in the label excerpts; (3) avoid naming specific vaccines (MMR/oral polio/varicella) and avoid providing half-life/elimination durations not included in provided label text; (4) remove claims about other products/patent term not present in the COSENTYX label.
