Guselkumab for Plaque Psoriasis
(SPECTREM Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a treatment called guselkumab to evaluate its effectiveness for people with moderate plaque psoriasis, particularly in areas like the scalp, face, and genitals. Participants will receive either guselkumab (an injection) or a placebo (an inactive substance) as an injection. The trial seeks individuals who have had plaque psoriasis for at least six months and have tried at least one topical treatment without success. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants an opportunity to contribute to the potential availability of a new treatment.
Do I need to stop my current medications for the trial?
The trial information does not specify if you need to stop your current medications. However, it does mention that participants should not have used certain biologic drugs before. It's best to discuss your current medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that guselkumab is safe for treating plaque psoriasis. Studies have found that people using guselkumab for up to five years experienced positive results and tolerated it well. Unwanted side effects were similar to those expected with other psoriasis treatments. Most side effects were mild, such as colds or headaches. Overall, clinical trials support guselkumab's safety for people with moderate-to-severe plaque psoriasis.12345
Why do researchers think this study treatment might be promising for plaque psoriasis?
Guselkumab is unique because it specifically targets interleukin-23 (IL-23), a protein that plays a key role in the inflammation process of plaque psoriasis. Unlike many standard treatments, such as methotrexate or cyclosporine, which broadly suppress the immune system, guselkumab offers a more targeted approach, potentially reducing side effects. Researchers are excited about guselkumab because its targeted action not only promises effectiveness in reducing psoriasis symptoms but also enhances safety by minimizing the impact on the rest of the immune system.
What evidence suggests that guselkumab might be an effective treatment for plaque psoriasis?
Research has shown that guselkumab, which participants in this trial may receive, effectively treats plaque psoriasis. In clinical studies, patients experienced significant improvements in symptoms like itching, burning, and skin pain by week 16. About 64% of patients achieved nearly clear skin at this time. Another study found that guselkumab helped most adults with moderate plaque psoriasis, even when it affected a small area of their body, to achieve clear or almost clear skin. This treatment demonstrated meaningful improvements in disease activity and patient-reported outcomes over 9–12 months. Overall, guselkumab consistently delivers strong results in clearing skin and reducing psoriasis symptoms.12678

Are You a Good Fit for This Trial?
This trial is for individuals with a diagnosis of moderate plaque psoriasis covering a low area of the body, who haven't responded well to or can't tolerate at least one topical treatment. They should be eligible for light therapy or systemic treatment and have had psoriasis for over six months. People with non-plaque psoriasis, drug-induced psoriasis, certain palmoplantar conditions, previous biologic treatments, or chronic infections cannot participate.Inclusion Criteria
