History: No changes posted

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

Detailed Description:

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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Known severe persistent corticosteroid dependent asthma (WHO/NHLBI workshop definition).
  • Disease duration > 1 year.
  • Stable disease with no exacerbation episode for at least one month before inclusion.
  • Daily treated with 10 to 50 mg of equivalent prednisolone, with stable dosage since at least 3 months.
  • Known reversibility of bronchial obstruction, defined as an enhancement of FEV1 ≥ 12%, 10 minutes after salbutamol administration, or 14 days after systemic treatment with 1 mg/kg/day of equivalent prednisolone.

Exclusion Criteria:

  • Asthmatic patients still exposed to allergens or to triggering factors influencing asthma control.
  • History of infection requiring hospitalization or treatment with antibiotics within 2 weeks of screening.
