Summary
Brief summary
Psoriasis is an immune-mediated disease that causes raised, red, scaly patches to appear on the skin as a result of a sped-up skin production process. The typical life cycle of a skin cell is 1 month (www.healthline.com/health/psoriasis). Typically, skin cells grow deep in the skin and slowly rise to the surface and eventually fall off. In people with psoriasis, this production process may occur in just a few days resulting in rapid overproduction and build-up of skin cells.
This study is investigating a new vaccine called FPP003 which is being developed to treat patients with moderate - severe psoriasis. This study will investigate the safety and tolerability of FPP003. It will also look at the pharmacokinetics (how much of the drug remains in the blood at certain timepoints) of the drug and how effective it is with escalating dose levels. These investigations will be compared with placebo under the same conditions.
This study will be conducted in 4 successive, dose escalated, cohorts. In each cohort, participants will receive a subcutaneous dose of the study drug (FPP003 or placebo) on Day 1, Day 15 and Day 29. The study will be divided into a screening phase lasting up to 28 days. The total duration of the study for participants completing the study is about 5 months, with a total of 8 visits to the study unit.
