This is an early phase study to assess the safety and tolerability of ONO-4685 in patients with psoriasis. In addition, the study will assess how the drug is distributed and eliminated by the body (pharmacokinetics) and how the drug affects the body (pharmacodynamics). This will be done by measuring the amount of drug in the blood and measuring other markers in the body that might have been affected by ONO-4685. The study will also look at preliminary information on whether ONO-4685 might be effective in treating psoriasis.
The study will be split into three parts. Part A will assess a single dose of ONO-4685 in small groups of patients, each group planned to receive a higher dose than the last group. In Part B and C, patients will receive multiple doses of ONO-4685 over a period of 4 weeks.

This is a phase I, multi-centre study to assess the safety, tolerability, PK & PD of ONO-4685. This study consists of: Part A single ascending dose, Part B an assessment of multiple doses & Part C to undertake initial assessment of efficacy with multiple doses.
The study will recruit patients, male & female, with mild or moderate psoriasis diagnosed for at least 6 months. Following screening activities, patients are admitted to a clinical unit 1 day ahead of dosing and will stay at the unit for 4 nights. For patients receiving multiple doses, they will attend the clinic on the day of dosing and will stay for 3 nights. All patients will be followed up, for up to 24 weeks from 1st dose.
The study will recruit 6 patients per cohort for part A & B and 18 patients per cohort for part C. The overall active to placebo ratio will be 2:1.
