What is the purpose of this trial?

This trial tests a medication called tildrakizumab to determine its effectiveness for children and teens with moderate to severe plaque psoriasis, a skin condition causing red, itchy patches. The study evaluates the treatment's efficacy and safety for kids aged 6 to under 18 who have had psoriasis for at least six months and have not found success with other treatments like creams or light therapy. Researchers will divide participants into groups to compare tildrakizumab with a placebo and observe the effects of stopping and restarting the treatment. This trial may suit children and teens with psoriasis affecting a large part of their body that has not improved with other treatments. As a Phase 2, Phase 3 trial, it focuses on measuring the treatment's effectiveness in an initial, smaller group and represents the final step before FDA approval, offering hope for effective relief.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop your current medications. However, you cannot use topical therapy, phototherapy, or additional systemic therapy for psoriasis during the trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that tildrakizumab is generally safe for patients. Earlier studies found no major safety issues. Common side effects include mild reactions such as colds and injection site reactions, similar to those seen with a placebo. Tildrakizumab is already approved for adults with psoriasis, indicating its safety for that group. However, this trial specifically tests its use in children and teens with psoriasis. The progression of this study into later stages suggests that earlier tests did not identify any major safety problems. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Tildrakizumab is unique because it targets the IL-23 pathway, a key driver in psoriasis, offering a more focused approach than some traditional treatments like methotrexate or cyclosporine. Unlike these broader immunosuppressants, Tildrakizumab specifically blocks a part of the immune system involved in the inflammatory process of psoriasis, potentially leading to fewer side effects. Researchers are excited about this treatment because it promises improved efficacy with a targeted action, which might result in better skin clearance and a more favorable safety profile for pediatric patients.

What evidence suggests that this trial's treatments could be effective for pediatric psoriasis?

Research has shown that tildrakizumab, which participants in this trial may receive, works well for treating psoriasis. In one study, it consistently reduced psoriasis symptoms over five years. Another study found that it improved patients' mental well-being within 16 weeks. Tildrakizumab has also significantly improved the severity of psoriasis, with many patients experiencing major improvements in their skin. These findings suggest that tildrakizumab can effectively manage psoriasis symptoms in children. ^{1 2 3 4 6}

Are You a Good Fit for This Trial?

This trial is for children and teens aged 6 to <18 with moderate to severe plaque psoriasis, who haven't responded well to topical treatments or phototherapy. They must weigh at least 15 kg and have a confirmed diagnosis of plaque psoriasis for over six months. Participants should not have recent serious infections, HIV, hepatitis B/C, significant lab abnormalities, or be pregnant.

Published Research Related to This Trial

Alefacept is an effective treatment for chronic plaque psoriasis, safely reducing disease symptoms by selectively inducing apoptosis in CD2(+) memory-effector T cells, as shown in phase II and III clinical trials.

The mechanism of action involves alefacept activating intracellular signals through interactions with CD2 and Fc gamma RIII (CD16), which leads to the activation of immune cells and the induction of apoptosis in target cells, highlighting its role as an immunomodulatory agent.

A study of 87 donors revealed that the Fc gamma receptor IIIa (CD16) polymorphism at position 158 significantly affects IgG binding, with the 158V variant binding more IgG than the 158F variant.

The findings suggest that the differences in IgG binding among various Fc gammaRIIIa isoforms are linked to the 158V/F polymorphism, indicating its potential role in immune response variations among individuals.

Tildrakizumab, an antibody for treating moderate-to-severe chronic plaque psoriasis, shows a favorable efficacy profile, with 62.2% of patients achieving a 75% improvement in psoriasis severity (PASI75) at week 12, based on data from three clinical trials involving 2,717 participants.

The recommended dosing regimen is 100 mg every 12 weeks for most patients, but those weighing over 90 kg may benefit from a higher dose of 200 mg every 12 weeks, ensuring optimized treatment based on body weight.

A 3-year-old boy with recurrent viral infections exhibited an unusual CD16 phenotype on his natural killer (NK) cells, which may indicate a potential immunodeficiency related to his NK cell function.

Genetic analysis revealed a specific mutation in the Fc gamma RIIIA gene that alters the CD16 receptor, suggesting that this change could be linked to the boy's increased susceptibility to viral infections, warranting further investigation into the clinical implications of this genotype.

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.
