Summary
Many dosing-related and safety incidence claims are contradicted or unsupported by the supplied Cosentyx prescribing information (notably incorrect plaque psoriasis/pediatric weight dosing and incorrect PsA/AS loading/maintenance and ranges). Several efficacy timing and adverse event incidence estimates are absent from the label.
Category Scores
Accurate Statements
In PsA, Cosentyx can be combined with methotrexate if needed.
Supported: Dosage and Administration (2.4) states COSENTYX may be administered with or without methotrexate.
Cosentyx is indicated for moderate to severe plaque psoriasis in adults and pediatric patients 6 years and older; active PsA in adults and pediatric patients 2 years and older; and active AS in adults and pediatric patients 12 years and older.
Supported: Indications and Usage (1.1, 1.2, 1.3). (Note: claim wording said 'severe plaque psoriasis' and 'severe plaque psoriasis, PsA, AS'; label uses 'moderate to severe plaque psoriasis' but indications are otherwise consistent.)
Unsupported Statements
The described Cosentyx dosing applies to adults and children over 6 with plaque psoriasis weighing more than 90 kg.
Not supported in the provided label excerpt; plaque psoriasis pediatric dosing is weight-based for <50 kg (75 mg) and ≥50 kg (150 mg) (2.3), not >90 kg.
Clinicians assess AS severity using disease activity scores such as ASDAS.
No ASDAS assessment instruction appears in the supplied label sections; the AS trial description references BASDAI/BASFI/etc. (14.4) but does not support ASDAS usage.
In severe psoriasis trials, peak efficacy appears by weeks 12–16 with PASI 90 response in 70–80% of patients.
The supplied label excerpt includes PASI 90 response at Week 12 but does not provide 'peak efficacy by weeks 12–16' nor '70–80% PASI 90'. (14.1).
For PsA/AS, pain and function improve within 2–4 weeks.
No such 2–4 week timeframe for pain/function improvement is provided in the supplied sections (14.3, 14.4).
For PsA/AS, full benefits appear by week 16.
No 'full benefits' timing statement is provided in the supplied label excerpts (14.3, 14.4).
With 300 mg dosing in severe cases, infections (upper respiratory) occur in 20–30% of patients.
The supplied label provides infection increases overall and gives examples of infection rates, but the specific 'upper respiratory 20–30%' incidence range is not supported in the provided excerpts (5.1, 6.1).
Cosentyx use requires monitoring for IBD flares.
Partially supported (5.4 says monitor for signs and symptoms of IBD), but the claim is framed as a specific monitoring requirement for 'IBD flares'; other safety issues in the response are inaccurate.
Cosentyx dosing may be reduced to 150 mg if well-controlled.
Not supported as an instruction or rule in the provided dosing recommendations (2.3, 2.4, 2.6).
Cosentyx should be discontinued if there is no response by weeks 12–16.
No discontinuation instruction at 12–16 weeks is stated in the supplied label excerpts (2.3, 2.4, 2.6, 14.1, 14.3, 14.4).
There is no dose cap for severity.
The supplied label excerpt does not support a statement about 'no dose cap'; dosing described includes specific regimen options and weight-based dosing for plaque psoriasis.
Contradictions
High
AI Statement
For severe plaque psoriasis, patients under 90 kg or with milder severity may receive 150 mg after loading.
Label Reference
Contradicted by plaque psoriasis dosing: In adults, recommended 300 mg at Weeks 0–4 and every 4 weeks thereafter; for some patients, 150 mg may be acceptable (2.3). The label does not state a threshold of 'under 90 kg' or 'after loading' as described.
High
AI Statement
Children aged 6 years and older with plaque psoriasis weighing 50–90 kg receive a 150 mg loading dose ... then 150 mg every 4 weeks.
Label Reference
Contradicted by pediatric plaque psoriasis weight-based dosing provided: patients <50 kg: 75 mg; patients ≥50 kg: 150 mg (2.3). The label excerpt does not specify a 50–90 kg band; it gives ≥50 kg without an upper cutoff.
High
AI Statement
Severe PsA or AS follows the same 300 mg loading regimen and then 150–300 mg every 4 weeks based on response.
Label Reference
Contradicted by PsA and AS dosing regimens: PsA loading is 150 mg (2.4) and AS loading is 150 mg (2.6), with consideration to increase to 300 mg every 4 weeks if active disease persists; the label does not support 'same 300 mg loading regimen' nor a stated 150–300 mg range as the initial loading regimen.
Medium
AI Statement
With 300 mg dosing in severe cases, diarrhea occurs in 10% of patients.
Label Reference
Contradicted by PsO trial adverse reaction rates: diarrhea 4.1% (300 mg) (and 2.6% for 150 mg) in the supplied Table 2 excerpt (6.1).
Important Omissions
The response does not correctly present label-supported, weight-based pediatric plaque psoriasis dosing cutoffs and does not provide the label-supported PsA and AS loading dosing (150 mg with loading for PsA/AS; possible consideration to increase to 300 mg every 4 weeks for persistent active disease).
Importance:
High
Safety Assessment
Potential Patient Risk:
High
Multiple contradicted dosing statements (including pediatric weight bands and PsA/AS loading/maintenance regimen) and at least one contradicted adverse reaction incidence claim (diarrhea) could directly lead to incorrect dosing or misinformed risk expectations.

Primary Issue
Contradicted plaque psoriasis pediatric/weight/severity dosing statements and contradicted PsA/AS dosing regimen assertions; plus contradicted diarrhea incidence.
Suggested Improvement
Replace all contradicted/unsupported dosing and incidence statements with the specific label regimens: plaque psoriasis adults 300 mg SC at Weeks 0–4 then every 4 weeks (with possible 150 mg acceptability for some patients per 2.3); pediatric PsO dose thresholds (<50 kg 75 mg; ≥50 kg 150 mg, 2.3); PsA loading 150 mg at Weeks 0–4 then every 4 weeks (consider increasing to 300 mg every 4 weeks for persistent active disease, 2.4); AS loading 150 mg at Weeks 0–4 then every 4 weeks (consider increasing to 300 mg every 4 weeks for persistent active disease, 2.6). Remove unsupported efficacy timecourse claims and ensure adverse reaction incidence numbers match the label tables.
