Detaillierte Beschreibung

This is a global, multicenter, randomized, double-blind, placebo-controlled Phase 3 study to evaluate the efficacy and safety of GB-0895 adjunctive therapy in adults and adolescents with severe uncontrolled asthma with an optional open-label extension (OLE). The trial is designed to administer GB-0895 an investigational drug or placebo, subcutaneously every 6 months.

The study is divided into several phases as described below:

  • Screening/Run-In (Weeks -5 to 0)
  • Treatment (Weeks 0 to 52)
  • Follow-up (Weeks 52 to 90) or optional open-label extension (OLE, Weeks 52 to 142)
