Trial summary

Psoriasis is a skin disorder that is chronic proliferative and inflammatory in nature. Extensor surfaces, scalp, and lumbosacral area are covered in erythematous plaques with silvery scales. The disease can also impair the eyes and joints. It has no cure. Read more about this study

About this study

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

Psoriasis is a skin disorder that is chronic proliferative and inflammatory in nature. Extensor surfaces, scalp, and lumbosacral area are covered in erythematous plaques with silvery scales. The disease can also impair the eyes and joints. It has no cure. Because of their low quality of life, many psoriasis patients experience depression. In addition to the cutaneous manifestations, it is associated with an increased risk of psoriatic arthritis, depression and cardiovascular disease.

Read the detailed description

Psoriasis is known to be affecting 3% to 4% of the general population worldwide. While the prevalence of psoriasis in Egypt ranges 0.19-3% Psoriatic arthritis (PsA) most commonly develops in 20-30% of psoriatic patients with preceding psoriasis or develops concomitantly with psoriasis, and it manifests all features of arthritis, including enthesitis.

The pathogenesis of psoriasis is multifactorial, involving a complex interplay between genetic predisposition, immune system dysregulation, and environmental triggers. Central to the disease process is the activation of T-cells, particularly Th1, Th17, and Th22 subsets, which release pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α), interleukin-17 (IL-17), and interleukin-22 (IL-22)

. These cytokines drive the abnormal growth and differentiation of keratinocytes and induce the inflammatory cascade that results in the characteristic skin lesions. Genetic factors, including polymorphisms in genes related to the immune system, such as HLA-Cw6.Additionally, environmental factors like infections, stress, and trauma (Koebner phenomenon) can exacerbate or trigger the onset of the disease.

The Psoriasis Area and Severity Index (PASI) is a widely used tool for assessing the severity of psoriasis and evaluating treatment efficacy. It combines the extent of skin involvement and the degree of erythema, scaling, and thickness across four body regions: the head, upper limbs, trunk, and lower limbs. Each region is assigned a score for surface area involvement (0-6) and for each symptom (0-4), which are then combined to yield an overall PASI score ranging from 0 to 72. Higher scores indicate more severe disease. Typically, a PASI score below 10 suggests mild psoriasis, while scores between 10 and 20 indicate moderate severity, and scores above 20 reflect severe psoriasis. PASI serves as a critical endpoint to gauge disease burden.

Interleukin-12B (IL12B) encodes the p40 subunit shared by both IL-12 and IL-23, cytokines that are pivotal in the differentiation of naive T-cells into Th1 and Th17 cells, respectively. The IL-12/IL-23 axis is well-established in contributing to the immune pathology seen in psoriasis. Genetic studies have shown that polymorphisms within the IL12B gene are associated with an increased risk of psoriasis.

Single nucleotide polymorphisms (SNPs) are the most common type of genetic variation in humans. SNP rs3213094, located within the IL12B gene, has been identified as a potentially significant variant that could alter the expression or function of the cytokines involved in immune responses. Previous studies have suggested that SNP rs3213094 within the IL12B gene is associated with psoriasis, although the strength of this association varies across different populations.

Humira (adalimumab) is a monoclonal antibody targeting TNF-α, widely used for treating moderate-to-severe psoriasis and PsA. It works by neutralizing the activity of TNF-α, thereby reducing inflammation, decreasing keratinocyte proliferation, and alleviating joint symptoms. However, individual responses to Humira can vary significantly, with some patients experiencing limited or no therapeutic benefits

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Treatment of Psoriasis and Psoriatic Arthritis

    Treatment the patients whom suffering from Psoriasis and Psoriatic arthritis and Assessment of clinical improvement to Humira therapy according to: PASI score into PASI 50: means 50% reduction in PASI score - an acceptable measure of efficacy for secondary endpoints in psoriasis clinical trials PASI 75: means 75% reduction in PASI score - standard efficacy measure used in most psoriasis clinical studies1 PASI 90: means 90% reduction in PASI score (almost clear skin) PASI 100: means Completely clear skin.

    Measured: 3 Months

Secondary outcomes (1)
  1. Evaluate the effect of treatment with Humira

    Evaluate the effect of treatment with Humira therapy on the level of serum IL12B genetic polymorphism (rs3213094) on the Participants whom suffering from Psoriasis and Psoriatic arthritis.

    Measured: 3 Months

Questions about this trial

What is this clinical trial studying?

A study testing Humira in people with Psoriasis, run by South Valley University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 19 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
