IL12B (rs3213094) gene variant in people with psoriasis

Evaluation of IL 12B Genetic Polymorphism (rs3213094) in Patient With Psoriasis and Psoriatic Arthritis in Response to Humira

NA · South Valley University · NCT07128472

This test looks at whether a specific IL12B gene change (rs3213094) is linked to how people with moderate-to-severe psoriasis respond to Humira.

What this trial studies

This interventional study enrolls people with clinically diagnosed moderate-to-severe psoriasis who are being treated with Humira and genotypes them for the IL12B rs3213094 polymorphism. Participants receive standard Humira therapy while investigators collect clinical outcome measures, including PASI scores and assessments for psoriatic arthritis. The study aims to correlate the genetic variant with treatment response and disease features. Data will be analyzed to see if the IL12B variant predicts better or worse outcomes on Humira.

Who should consider this trial

Good fit: Adults with clinically diagnosed psoriasis for at least six months, severe disease (PASI >10 and >10% BSA) and who are receiving Humira are the intended participants.

Not a fit: People with other autoimmune or inflammatory conditions, active infections, pregnancy or lactation, known immune genetic disorders, contraindications to Humira, or those not on Humira are excluded and unlikely to benefit from the findings.

Why it matters

Potential benefit: If successful, this could help personalize psoriasis treatment by identifying patients more likely to respond to Humira based on their IL12B genotype.

How similar studies have performed: Genetic studies have linked IL12B variants to psoriasis risk, but using rs3213094 specifically to predict Humira response is relatively limited and not yet well established.

Eligibility criteria

Inclusion Criteria:

\- Patients having psoriasis diagnosed clinically for at least 6 months and who have a severity grade of severe, defined as a Psoriasis Area and Severity Index (PASI) score greater than 10, and involvement of greater than 10% of the body surface area (BSA) with psoriatic arthritis.

Exclusion Criteria:

* Pregnancy and lactation.
* Patients currently undergoing any treatment other than Humira.
* Patients with known genetic disorders affect immune system function.

* Patients with active infections, including tuberculosis or chronic viral infections (e.g., hepatitis B or C, HIV).
* Patients with contraindication to Humira.
* Renal \&Vascular diseases
