| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| Objective 1: To demonstrate that MK-0633, compared with placebo, results in dose related improvement in FEV1 over the last 4 weeks of the 6-week active treatment period in patients aged 18 to 70 years with chronic asthma. 
 Objective 2: To determine the dose-related safety and tolerability of MK-0633 over
 6 weeks in patients aged 18 to 70 years with chronic asthma.
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| To demonstrate that MK-0633, compared with placebo, results in dose-related improvement in asthma symptoms scores (both daytime and nighttime) over the last
 4 weeks (diary data collected at weeks 4, 5 and 6) of the 6-week active treatment period in patients aged 18 to 70 years with chronic asthma.
 |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| Patient has a consistent clinical history, for at least 1 year, of symptoms of chronic asthma that may include, but are not limited to, dyspnea, wheezing, chest tightness, cough, and/or sputum production; While withholding short-acting β-agonists for at least 6 hours and LABAs for at least 14 hours (withholding LABAs for 12-14 hours is acceptable, but not preferred), patient has a FEV1 ≥45% and ≤85% of the predicted value, documented at least once during Visits 1 or 2; While withholding short-acting β-agonists for at least 6 hours and LABAs for at least 14 hours (withholding LABAs for 12-14 hours is acceptable, but not preferred), patient has evidence of reversibility of airway obstruction defined as an increase of FEV1 of 12% or greater 20 to 30 minutes after β-agonist administration, documented at least once during Visit 1 or 2; Patient has a daytime and nighttime β-agonist administration average ≥1 puff per day, as recorded on the patient’s diary card between Visits 2 and 3. |  | 
| E.4 | Principal exclusion criteria | 
| Patient has evidence of another clinically significant, active pulmonary disorder such as bronchiectasis or COPD documented by history, physical examination, or chest x-ray; Patient has a clinically unstable disease of the ophthalmologic, neurological, hepatic, renal, connective tissue, genitourinary, gastrointestinal, cardiovascular or hematologic systems.; Patient has any of the following abnormalities on screening (Visit 1) laboratory studies:	Impaired renal function defined as creatinine ≥1.5 mg/dL; or Hemoglobin <11 g/dL; or WBC count <3000/mm3 ; or Platelet count <100,000/mm3; or Alanine aminotransferase (ALT) or Aspartate aminotransferase (AST) levels >1.5 times the upper limits of normal (ULN). Note:  One retest will be allowed for patients at Visit 1 with: ALT and/or AST >1.5 x ULN and ≤2 x ULN.; Patient is unable to comply with the study procedures or protocol, including completion of the diary card and compliance with study medication.; Patient is unable to perform acceptable, reproducible spirometry; Patient has required an oral corticosteroid rescue for worsening asthma between Visit 1 and Visit 2 or between Visit 2 and Visit 3.
