Category Scores
Accurate Statements
Stelara targets and blocks the activity of IL-12 and IL-23.
Supported via binding to the p40 subunit used by both IL-12 and IL-23 and disruption of IL-12/IL-23 mediated signaling (12.1).
Stelara is administered via injection.
Label provides subcutaneous administration guidance/dosing (2.6) and dosing regimens (2.1, 2.2).
Stelara is approved for moderate to severe plaque psoriasis.
Indicated for adults and pediatric patients 6 years of age and older with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy (1.1).
Stelara is approved for active psoriatic arthritis.
Indicated for adults and pediatric patients 6 years of age and older with active psoriatic arthritis (1.2).
Stelara is approved for moderately to severely active Crohn's disease.
Indicated for adults and pediatric patients 2 years of age and older with moderately to severely active Crohn's disease (1.3).
Stelara can cause injection site reactions.
Injection site erythema and other injection site reactions appear in adverse reactions data (6.1).
Stelara can cause headache.
Headache appears in adverse reaction tables (e.g., 6.1 Table 8 and UC data in 6.1).
Stelara can cause fatigue.
Fatigue appears in adverse reaction tables (6.1 Table 8).
Stelara can cause nausea.
Nausea listed as adverse reaction in psoriatic arthritis and ulcerative colitis data (6.1).
Stelara may interact with live vaccines (avoid live vaccines).
Patients being treated should avoid receiving live vaccines (5.7).
Stelara is contraindicated in patients with clinically significant hypersensitivity to ustekinumab products or excipients.
Contraindication stated in 4 (4 CONTRAINDICATIONS (4)).
Stelara should not be administered to patients with active tuberculosis infection.
Avoid administering STELARA to patients with active tuberculosis (5.3).
Unsupported Statements
IL-12 and IL-23 play a key role in the inflammation process.
Label states they are involved in inflammatory/immune responses (12.1) but does not explicitly support the phrasing 'key role.'
Stelara binds to IL-12 and IL-23.
Label describes binding to the p40 subunit used by both IL-12 and IL-23 (12.1), not explicitly that it binds directly to IL-12 and IL-23.
Stelara prevents IL-12 and IL-23 from interacting with their receptors on immune cells.
Label describes disruption of cytokine signaling by disrupting interaction with a shared receptor chain IL-12Rβ1 (12.1), but does not explicitly use the receptor-interaction phrasing.
Blockade of IL-12 and IL-23 reduces the production of pro-inflammatory cytokines.
Provided label text does not explicitly state this outcome.
Reduction in pro-inflammatory cytokines decreases inflammation.
No explicit link in provided label text between reduced pro-inflammatory cytokines and decreased inflammation.
Decreased inflammation reduces symptoms.
No explicit statement in provided label sections connecting decreased inflammation to symptom reduction.
Stelara provides rapid and sustained improvement in symptoms.
No such timing/descriptor supported in the provided label sections.
Stelara reduces inflammation and scarring.
No explicit statement about scarring or inflammation reduction in the provided label sections.
Stelara improves quality of life.
No explicit quality-of-life claim present in provided label sections.
Stelara is not yet available in generic form.
Generic availability is not addressed in provided label sections.
Some patients may experience improvement within 2-4 weeks after starting Stelara.
No such improvement timing appears in provided label sections.
Stelara may interact with immunomodulators.
Label discusses concomitant immunomodulators and effects on safety/efficacy rather than an explicit 'interaction' statement in the usual sense (7.1).
Stelara may interact with biologics.
No explicit statement in provided label sections about biologics interactions.
Stelara may be used in combination with other medications, including immunomodulators and biologics.
Label in 7.1 supports concomitant immunomodulators/corticosteroids but does not explicitly address combinations with biologics in the provided section.
According to DrugPatentWatch.com, the patent for Stelara is set to expire in 2028.
Patent information from external sources is not in provided label sections.
The patent expiration may lead to increased competition and potentially lower prices.
No pricing/competition statement in provided label sections.
Researchers are exploring the use of Stelara in other autoimmune diseases, including multiple sclerosis and rheumatoid arthritis.
No such research exploration statements in provided label sections.
Studies are underway to investigate the long-term safety and efficacy of Stelara.
No 'studies underway' statement in provided label sections.
Contradictions
High
AI Statement
Stelara is administered every 4 weeks.
Label Reference
Dosing regimens: psoriasis/psoriatic arthritis maintenance every 12 weeks after Weeks 0 and 4 (2.1, 2.2); Crohn's maintenance every 8 weeks after IV induction (2.3).
High
AI Statement
The recommended dosage of Stelara is 45 mg administered via injection every 4 weeks for psoriasis and psoriatic arthritis.
Label Reference
Psoriasis/psoriatic arthritis: 45 mg initially and 4 weeks later, followed by 45 mg every 12 weeks (2.1, 2.2).
High
AI Statement
The recommended dosage of Stelara is 6 mg/kg administered via injection every 8 weeks for Crohn's disease.
Label Reference
Crohn's: weight-based single IV induction dose, then 90 mg subcutaneous maintenance every 8 weeks; no maintenance regimen stated as 6 mg/kg (2.3).
Important Omissions
Dosing differs by indication, weight, and route (e.g., psoriasis/psoriatic arthritis after Weeks 0 and 4 then every 12 weeks; Crohn's induction IV then maintenance SC every 8 weeks).
Importance:
High
Label contraindications are specific to clinically significant hypersensitivity; the response also states a contraindication for 'severe infections' without label support.
Importance:
Moderate
Concomitant therapy guidance includes immunosuppressive agents/phototherapy not evaluated in psoriasis trials (7.1).
Importance:
Low
Safety Assessment
Potential Patient Risk:
High
Contradictory dosing frequency/dose claims ('every 4 weeks' and '6 mg/kg every 8 weeks') conflict with label-directed regimens, creating substantial risk of incorrect administration.

Recommendation

Primary Issue
Dosing frequency/dose claims directly contradict the label (2 DOSAGE AND ADMINISTRATION).
Suggested Improvement
Replace 'every 4 weeks' and '6 mg/kg every 8 weeks' with label-supported regimens: psoriasis/psoriatic arthritis maintenance every 12 weeks after Weeks 0 and 4; Crohn's maintenance subcutaneous 90 mg every 8 weeks following IV induction.
