Clinical Trial Summary

The purpose of this first-in-human study is to investigate the safety and tolerability of ABY-035 when administered intravenously and subcutaneously, to healthy volunteers and to psoriasis patients.

Description:

This first in human study with ABY-035 (a novel IL-17A inhibitor (interleukin 17A)) consists of four Parts. Part A consists of a single ascending intravenous dose study with 40 healthy volunteers divided into five dose cohorts. Each group consists of 8 subjects where 6 subjects will receive ABY-035 and 2 will receive placebo. The subjects will be followed for pharmacokinetic and safety assessments up to Day 95 after dosing.

Part B of the study consists of 6 healthy volunteers who will be given a single subcutaneous dose of ABY-035. The subjects will follow the same study visit schedule as Part A.

Part C of the study will include up to 12 moderate-to-severe psoriasis patients who each patient will be given a single intravenous dose of ABY-035. The patients will follow the same study visit schedule as Part A and B.

Part D of the study will include up to 18 psoriasis patients (mild, moderate or severe). Each patient will participate in 3 or 7 biweekly dosing occasions of subcutaneously administered ABY-035. Patients will be followed regularly for safety, efficacy and pharmacokinetics for 8 weeks post-final dose.
