(PAMPA)
What this study is about
This is a multi-center (North-America), randomly assigned, where neither patients nor doctors know which treatment is given, compared against an inactive treatment, wait-list, interventional, preventive trial of guselkumab in high-risk psoriasis patients compared to non-biologic the usual treatment.
View original scientific description
This is a multi-center (North-America), randomized, double-blind, placebo-controlled, wait-list, interventional, preventive trial of guselkumab in high-risk psoriasis patients compared to non-biologic standard of care.
Interventions
DRUG
Guselkumab
Guselkumab 100 mg 1 mL liquid formulation in a single-dose pre-filled syringe administered by subcutaneous injection at Week 0, Week 4 and every 8 weeks thereafter (month 0 to month 24 for arm 1; week 24 to month 24 for arm 2).
DRUG
Placebo
• Placebo to Guselkumab 1 mL liquid formulation in a single-dose pre-filled syringe administered by subcutaneous injection at Week 0, Week 4 and every 8 weeks thereafter (Month 0 to Week 20 for Arm 2).
Primary outcome measures
Change in Musculoskeletal, Power Doppler Ultrasound (MSK-PDUS) Composite Score
Time frame: Baseline, Week 24
Score is defined by the ultrasound (General Electric Logiq E9 or E10) equipment, not calculated through a scale.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
