Guselkumab for Psoriasis
(TIG Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests guselkumab, a treatment for psoriasis, to evaluate its effectiveness for individuals with plaque or guttate psoriasis. Researchers aim to understand how well this treatment reduces symptoms and what genetic factors might influence its effectiveness. Participants will receive regular doses of guselkumab and will be monitored for changes in their condition. Individuals with chronic plaque psoriasis for over 5 years or new-onset guttate psoriasis within the last year may be suitable for the trial. As a Phase 4 trial, this research seeks to understand how this already FDA-approved and effective treatment benefits more patients.
Do I need to stop my current medications to join the trial?
The trial information does not specify if you need to stop taking your current medications. However, if you have previously been treated for psoriasis with certain therapies like phototherapy, systemic agents, or biologic agents, you may not be eligible to participate.
What is the safety track record for this treatment?
Research shows that guselkumab, the treatment under study in this trial, is generally safe for people with psoriasis. Studies have found that adults with moderate-to-severe plaque psoriasis usually tolerate guselkumab well. Used for over five years, it has demonstrated a good safety record. The most common side effects are mild, such as upper respiratory infections, and occur in less than 1% of people.
Evidence also supports guselkumab's safety for children with moderate to severe plaque psoriasis, reinforcing its safety for many patients. Overall, research suggests that guselkumab is a safe option for treating psoriasis.12345Why are researchers enthusiastic about this study treatment?
Guselkumab is unique because it specifically targets interleukin-23 (IL-23), a protein that plays a key role in the inflammation and overproduction of skin cells seen in psoriasis. Unlike traditional treatments like methotrexate or cyclosporine, which can have broad immune-suppressing effects, guselkumab offers a more targeted approach, potentially reducing side effects. Researchers are excited about guselkumab because its precise action may lead to longer-lasting results and fewer relapses while improving the quality of life for those with chronic plaque and new-onset guttate psoriasis.
What is the effectiveness track record for guselkumab in treating psoriasis?
Research has shown that guselkumab effectively treats both plaque psoriasis and guttate psoriasis. In this trial, participants with chronic plaque psoriasis will receive guselkumab, and 64% of patients in previous studies experienced significant skin improvement, known as PASI 90, after 16 weeks. Real-world studies indicate that many patients report better disease control and quality of life with regular treatment. Participants with new-onset guttate psoriasis will also receive guselkumab, and early studies suggest it is promising, with improvements seen regardless of how long patients have had the condition. Overall, guselkumab has a history of reducing symptoms and clearing skin in people with psoriasis.678910

What Are the Treatments Tested in This Trial?
Interventions
- Guselkumab
Trial Overview
The trial is testing guselkumab's effects on two types of psoriasis: new-onset guttate and chronic plaque. It's an open-label study where all participants know they're receiving guselkumab and are monitored for how their immune system responds to the treatment.

Experimental Treatment
Subjects will initially be treated with guselkumab 100 mg SQ at weeks 0, 4, and then every 8 weeks thereafter until week 44. At week 44, patients who have not achieved PASI 50 (nonresponders) will be removed from the trial. Patients who achieve between PASI 50 and PASI 75 (partial responders) will continue on drug throughout the remainder of the study. Patients who achieve PASI 75 or greater at week 44 (responders) will have their guselkumab therapy withdrawn and re-treated upon relapse.
