What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)	An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between administration of study drug and up to Day 85 that were absent before treatment or that worsened relative to pre-treatment state.	Day 1 to 85

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Observed Serum Concentration	Serum concentration of omalizumab and MEDI4212 were measured for participants who received omalizumab and MEDI4212, respectively.	Pre-dose and post-dose on Day 1; Day 2, 3, 5, 8, 15, 22, 29, 43, 57 and 85
Number of Participants Exhibiting Anti-Drug Antibodies for MEDI4212 at Any Visit	Anti-drug antibodies for MEDI4212 were analyzed for participants who received placebo or MEDI4212 as per planned analysis.	Days 1 (pre-dose), 15, 43, and 85
Free Immunoglobulin E (IgE) Serum Concentration		Day -28 (Screening), -1, 1 (pre-dose), 2, 3, 5, 8, 15, 22, 29, 43, 57, and 85 for all groups; 2 hours post-dose on Day 1 for MEDI4212 300 mg Intravenous group only
