What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are QVM149, Salmeterol Xinafoate / Fluticasone Propionate, or Placebo to QVM149. The registry lists allocation as randomized. This study wants to measure the how well it works and safety of indacaterol acetate / glycopyrronium bromide / mometasone furoate (QVM149) compared to salmeterol xinafoate / fluticasone propionate in children from 12 to less than 18 years of age with asthma with pre-bronchodilator FEV1 ≥ 50 % of the predicted normal value for the participant.
They plan to enroll about 188 people at 27 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
