Primary Outcome Measures:

The primary objective is to evaluate the efficacy of AMG 317 compared with placebo as measured by change in Asthma Control Questionnaire (ACQ) symptom scores from baseline to week 12. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Change from baseline in frequency of rescue beta agonist use during week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
Change from baseline PEFR during week 12 (morning/evening, diurnal and inter-day variation) [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
Change in pre and post bronchodilator FEV1 at week 12 from baseline [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
Number of asthma symptom-free days [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
Change from baseline in daily asthma symptoms during week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
Safety endpoints: number of asthma exacerbations, antibodies, adverse events, and change in ECG, labs and vital signs [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
Change in AQLQ score at week 12 from baseline [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

Males or females 18 to 65 years of age at the time of screening
Baseline percent of predicted FEV1 ≥ 50% to ≤ 80% at screening
At least 12% reversibility over baseline FEV1 with beta agonist inhalation, which can be demonstrated in the office or documented by medical record within the past 12 months
Inhaled corticosteroid (ICS) ≥ 200 and ≤ 1000 µg/day fluticasone or equivalent. Stable ICS dose for ≥ 30 days before screening and dose expected to remain stable during treatment with investigational agent. Must have used ICS for at least the last 3 consecutive months before screening
If receiving allergen immunotherapy, a stable dose for > 3 months before screening and anticipated to remain stable for the duration of the study
Positive to skin prick or RAST
Ongoing asthma symptoms with ACQ score at screening and baseline ≥ 1.5 points
Nonsmoker or ex-smoker with < 10 pack-years (eg, 1 pack per day for 10 years) who stopped ≥ 1 year ago

Exclusion Criteria:

Acute asthma exacerbation requiring emergency room (ER) treatment or hospitalization within 3 months
History of endotracheal intubation for asthma-related exacerbation within 3 years of screening
Respiratory illness within 4 weeks of screening
History of chronic obstructive pulmonary disease (COPD) or other chronic pulmonary condition other than asthma
Received long-acting beta agonist, theophylline, inhaled anticholinergics, oral beta 2 agonists, or cromolyn therapeutics within 1 week of first run-in visit.
Leukotriene antagonists within 2 weeks before first run-in visit
Oral or parenteral corticosteroids within 6 weeks before first run-in visit
Live/attenuated vaccinations within 4 weeks of screening or during the study
Any uncontrolled, clinically significant systemic disease (eg, chronic renal failure, uncontrolled hypertension, liver disease)
