Multi-Center PAMPA Study

Preventing Arthritis in a Multi-Center Psoriasis At-Risk Cohort

Multi-Center PAMPA Study (NCT05004727) is a Phase 4 interventional studying Psoriasis, sponsored by NYU Langone Health. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

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. The primary objective of the proposed trial will be to test the hypothesis that a prolonged, unresolved skin inflammation coupled with musculoskeletal power-doppler ultrasound (MSKPDUS) abnormalities driven by IL-23 increase the risk for transition into PsA and that an intervention that targets one of these pivotal molecules (i.e., Guselkumab) will: 1. Diminish MSKPDUS findings at 24 weeks, and 2. Significantly reduce or prevent the emergence of synovio-enthesial phenotype at year 2.

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 176 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Psoriasis subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: 1. 18 years old or older; 2. Both male \& female; 3. Psoriasis diagnosis (per dermatologist) for at least 2 years (in at least 30% of participants); 4. Willing and able to provide willing to sign a consent form; 5. Fulfillment of HR-PsO criteria (Psoriasis (PsO) patients will meet the definition of HR if they fulfill the following criteria: a) PsO duration \>2 years and Psoriasis Body Surface Area (BSA) \>3% and positive imaging findings in MSKPDUS defined as a RM-PsASon score of \>3.36 Who Should NOT Join This Trial: 1. Evidence of inflammatory joint pain, enthesitis and/or dactylitis on exam; 2. Current systemic immunosuppressive medication use (i.e., methotrexate, apremilast) at the time of enrollment or biologic therapy (ever); 3. RA seropositivity (mid-high RF/ACPA titers); 4. Current active malignancy; 5. History of symptomatic polyarticular OA or other joint conditions (such as RA, gout, etc) that may impair the ability to assess for PsA development 6. Conditions where initiation of guselkumab is prohibited in the prescribing information, including clinically important active infection and untreated latent tuberculosis; 7. Known hypersensitivity to the study agent. Always talk to your doctor about whether this trial is right for you.

Bring the printable summary of this trial — including the NCT ID (NCT05004727), the sponsor (NYU Langone Health), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?
