研究概览

简要总结

The aim of the study is to evaluate, comparatively to a placebo, the activity of oral AB1010, administered at three dose levels during 4 months to patients with severe persistent corticosteroid dependent asthma, assessed on :

  • the decrease in corticosteroid therapy
  • the asthma control improvement (symptomatic scores, rescue medication intake, respiratory function)
  • the pharmacokinetic profile of AB1010
  • clinical and biological safety parameters

详细描述

This is a double-blind, placebo-controlled, randomized, parallel-groups, multicenter study of daily oral AB1010 at doses 3, 4.5 and 6 mg/kg/day.

The study treatment is administered for 16 weeks:

  • the first 4 weeks are a run-in period during which corticosteroids remain stable;
  • during the following 8 weeks, corticosteroids are decreased every week until weaning or an exacerbation occurs;
  • the last 4 weeks are a stabilization period. Patients have to perform a visit every 2 weeks during run-in, then every week for the following 3 months.
