E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that MK-1029, compared with placebo, increases lung function when added to montelukast. |
|
E.2.2 | Secondary objectives of the trial |
1)Key Secondary Objective: To demonstrate that MK-1029, compared with placebo, improves control of asthma when added to montelukast.
2)Objective: To characterize the safety and tolerability of MK-1029, when added to montelukast, during 6 weeks of treatment.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time. |

E.3 | Principal inclusion criteria |
•Male/Female subjects between the ages of 18 and 65
•Have a consistent clinical history, for at least one year, of symptoms of persistent asthma that may include, but are not limited to, dyspnea, wheezing, chest tightness, cough, and/or sputum production.
•Must have documented SNP+ test result prior to Visit 2
•Have acceptable lung function at Visit 2 and Visit 4:
FEV1 ≥55% and ≤85% of the predicted value (or, ≥60% and ≤90% of the predicted value if subject is receiving controllers) at Visit 2, after withholding inhaled beta-agonist bronchodilators prior to spirometry (see section 5.5.1);
AND FEV1 ≥50% and ≤85% of the predicted value at Visit 4
•Have evidence of reversibility of airway obstruction, defined as an increase in FEV1 of at least 12% and at least 200mL when measured 10 to 30 minutes following short-acting beta-agonist (SABA)
•Have a history of asthma treatment, prior to Visit 1, that is in one of two categories (see section 4.2.1.3):
Controllers: Receiving stable doses of low- or medium-dose ICS, combination ICS/LABA, and/or other asthma controller medications; and (based on investigator’s judgment) can tolerate tapering of these controllers (e.g., ICS) or discontinuing these controllers (i.e., non-ICS) while receiving montelukast 10mg once daily (QD) starting at Visit 3; OR
Non-controllers: Not receiving asthma controller medications, and using only “as-needed” inhaled SABAs, for ≥4 weeks prior to Visit 1.
•Agree at Visit 3 to discontinue controllers (e.g., leukotriene antagonists other than montelukast), or taper them (e.g., ICS) over 2-4 weeks (as described in Appendix 12.10). Also, agree at Visit 3 to begin montelukast 10 mg QD.
•Have a daytime and nocturnal SABA administration average ≥1 puff per day, as recorded on the subject’s e-Diary for the last 7 days prior to Visit 4.
•Have an ACQ-6 score meeting the following requirements.
Non-controllers: At Visit 2, must have an ACQ-6 score ≥1.5 and a score between 1 and 6 for Question #6. At Visit 4, must have an ACQ-6 score ≥1.5.
Controllers: Visit 4 must have an ACQ-6 score ≥1.5.
•Not be pregnant

E.4 | Principal exclusion criteria |
•Is unable to perform acceptable, repeatable spirometry.
•Has evidence of another clinically significant, active pulmonary disorder, such as bronchiectasis or COPD, documented by history, physical examination, or chest x-ray.
•Has been treated in an emergency room for asthma within 4 weeks of Visit 1 or has been hospitalized for asthma or respiratory condition within 2 months prior to Visit 1.
•Has had an upper respiratory tract infection (viral or bacterial) within 1 month prior to Visit 1.
•Has evidence of active, clinically significant sinus disease within 2 weeks prior to Visit 1.
•Experiences a clinically significant deterioration of asthma between Visit 2 and Visit 4. A significant deterioration of asthma is defined as one or more of the following:
Decrease in absolute FEV1 (in L) by 20% or more from the FEV1 at Visit 2;
Decrease in %-predicted FEV1 to less than 50% of the predicted value;
Clinical asthma exacerbation requiring emergency treatment, hospital admission (serious AE), or treatment with additional asthma medication (other than SABAs).
