Phase II Study to Evaluate the Efficacy of AMG 317
February 23, 2016 updated by: Amgen
A Randomized, Double-blind, Placebo-controlled, Multiple Dose Phase 2 Study to Determine the Safety and Efficacy of AMG 317 in Subjects With Moderate to Severe Asthma
A Multi-center, Randomized, Placebo, Multi-Dose study 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.

Description
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)
