Is this trial a fit for you?
✓Likely a good fit
Adults with confirmed stable plaque psoriasis for at least 2 months, having two or more psoriatic plaques, and BMI 18–35 kg/m2.
✕Probably not a fit
People outside the eligibility criteria or with certain psoriasis subtypes may not experience benefit from ZP9830.

What this trial studies
This first-in-human phase 1 trial evaluates repeated administration of ZP9830 over an 8-week treatment period in adults with stable plaque psoriasis. The study primarily assesses safety and tolerability, and also explores preliminary clinical efficacy, pharmacokinetics, and pharmacodynamics. Participants are randomized to receive ZP9830 or placebo, with careful monitoring for adverse events and treatment effects. Eligible participants have confirmed plaque psoriasis with at least two plaques and a body mass index between 18 and 35 kg/m2. The trial is conducted at the Centre for Human Drug Research in Leiden, with Zealand Pharma as the lead sponsor and collaborators from CHDR and ICON Clinical Research.
Why it matters
Potential benefit: If successful, participants may experience improvement in psoriasis symptoms and gain information that could guide future dosing and development of ZP9830.
How similar studies have gone: Earlier phase studies in similar approaches have shown safety signals and signals of clinical activity, supporting further evaluation in psoriasis.
