What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines how tildrakizumab affects immune cells in the skin and blood of individuals with psoriasis. Psoriasis causes skin cells to accumulate, forming itchy, dry patches. The study aims to assess the effectiveness of tildrakizumab, which blocks a protein involved in inflammation, in individuals with moderate to severe psoriasis covering more than 5% of their body. Candidates for this trial include those who have not recently taken certain immune-suppressing drugs and have no serious infections or cancers. As a Phase 4 trial, this research seeks to understand how the already FDA-approved and effective treatment benefits a broader range of patients.

Will I have to stop taking my current medications?

The trial requires that you have not taken systemic immunosuppressives (medications that suppress the immune system) in the last 4 weeks. If you are on such medications, you may need to stop them before participating.

What is the safety track record for tildrakizumab?

Research has shown that tildrakizumab is generally safe for treating psoriasis. In studies involving patients with moderate-to-severe plaque psoriasis, tildrakizumab was well-tolerated, causing no major problems. Researchers found no new safety issues. Another study found that patients using tildrakizumab experienced no unexpected side effects after 72 weeks of treatment. Overall, these findings suggest that tildrakizumab is a safe option for people with psoriasis, based on the evidence collected so far. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Tildrakizumab is unique because it targets a specific protein in the body called IL-23, which plays a key role in the inflammation that causes psoriasis. This is different from many standard treatments that target broader pathways and may have more side effects. Researchers are excited about tildrakizumab because its focused approach could mean better control of symptoms with potentially fewer side effects, offering a more tailored treatment option for people with psoriasis.

What is the effectiveness track record for tildrakizumab in treating psoriasis?

Research shows that tildrakizumab effectively treats moderate-to-severe plaque psoriasis. Studies have found that patients experience a steady decrease in psoriasis symptoms over several years. Real-world evidence supports this, indicating that tildrakizumab enhances patients' well-being and quality of life without introducing new safety issues. This treatment is already approved for psoriasis, confirming its effectiveness in managing the condition. ^{1 2 6 7 8}

Published Research Related to This Trial

In a 52-week study involving 237 adults with moderate-to-severe plaque psoriasis, tildrakizumab demonstrated high efficacy, with 90.91% of patients achieving at least a 75% reduction in psoriasis severity (PASI 75) and 58.68% achieving complete skin clearance (PASI 100) by Week 52.

The safety profile of tildrakizumab was favorable, with no significant adverse events reported, and no patients had to discontinue treatment due to side effects, indicating it is a well-tolerated option for psoriasis management in real-life settings.

In a study of 51 patients with moderate-to-severe plaque psoriasis who had previously failed biologic treatments, tildrakizumab showed significant effectiveness, with a marked reduction in the Psoriasis Area Severity Index (PASI) score from 19.2 at baseline to 0.6 at 48 weeks (P < 0.001).

The treatment also led to substantial improvements in Body Surface Area (BSA) and Dermatology Life Quality Index (DLQI) scores, indicating enhanced quality of life for patients, with significant results observed at both 12 and 48 weeks.
