Intervention MeSH terms: Montelukast
Phase: Phase 2
Study type: Interventional
Primary purpose: Treatment

Summary:

      The purpose of this study is to evaluate the effect of MK-1029 on lung function in the
      treatment of adults who have persistent asthma that is uncontrolled with the use of
      montelukast (ML). Participants will use randomized study drug (either MK-1029 or placebo) for
      two separate 4-week treatment periods. All participants will also use ML during the treatment
      periods. The primary hypothesis is that MK-1029 is superior to placebo in change from
      baseline in forced expiratory volume in one second (FEV1) at the end of the 4-week treatment
      period.
