Brief summary

The purpose of this trial is to compare the safety, tolerability, and efficacy of adding MK-1029 to montelukast in adults with persistent asthma that is uncontrolled while receiving montelukast alone. Participants will have a specific genetic marker for clinical efficacy of MK-1029. The primary hypothesis is that when added to montelukast, treatment with MK-1029 is superior to placebo, as demonstrated by an increase in forced expiratory volume in one second (FEV1), measured as the average change from baseline at the end of Week 4 and Week 6 of treatment.

Average Change From Baseline in Pre-dose FEV1 at Week 4 and Week 6

FEV1 is the amount of air, measured in liters, forcibly exhaled in 1 second. Pulmonary function tests were to be performed by participants in the morning before dosing. Data presented represents the average change from baseline at Week 4 and Week 6.

Time frame: Before the first dose (Baseline) and at the end of Weeks 4 and 6 of treatment

Population: Analysis population consists of randomized participants who received at least 1 dose of study drug.

Percentage of Days With Worsening Asthma Average Over Weeks 3 to 6

A day with worsening asthma was defined as any day during which any of the following occurred: a decrease from baseline in morning (AM) peak expiratory flow (PEF) of more than 20%; AM PEF less than 180 liters/minute (L/min); an increase in β-agonist use of more than 70% (and a minimum increase of at least 2 puffs); an increase from baseline in daytime asthma symptom score of more than 50%; overnight asthma symptom of: Awake all night; an asthma attack, as defined by any day when one or more of the following events due to asthma has occurred: corticosteroid use (systemic); unscheduled visit to the doctor or urgent care clinic; unscheduled visit to the emergency department; and/or hospitalization. Participants needed at least 80% of days with a complete diary during Weeks 3 to 6. A diary is considered complete if none of the above 6 components used to determine asthma worsening are missing.

Time frame: Up to 4 weeks

Population: Analysis population consists of randomized participants who received at least 1 dose of study drug and had at least 80% of days with a complete diary during Weeks 3 to 6 (a diary is considered complete if none of the 6 components used to determine asthma worsening are missing).
