Total NPS ranges from 0 to 8 (sum of 0-4 for left and right nasal passage scores per the following criteria), with a lower score indicating smaller-sized nasal polyps: 0 = No polyps; 1 = Small polyps in the middle meatus not reaching below the inferior border of the middle turbinate; 2 = Polyps reaching below the lower border of the middle turbinate (modified to accommodate those with a middle turbinectomy, such that polyp must have reached the top of the inferior turbinate.); 3 = Large polyps reaching the lower border of the inferior turbinate or polyps medial to the middle turbinate; and 4 = Large polyps causing complete obstruction of the inferior nasal cavity. Two blinded primary independent expert readers reviewed every post-screening recorded video endoscopy for a given participant to determine total NPS. A third reader chose one of the two scores to be used for analysis in cases where there was any discrepancy in total NPS assigned between the two primary readers.
The Nasal Congestion Score (NCS) was assessed daily by the participant via an electronic diary as the response to the following question: Is your nose blocked? The four available response options were scored from 0 (no symptoms) to 3 (severe symptoms): 0 = Not at all; 1 = Mild; 2 = Moderate; and 3 = Severe. For each study day, a score was calculated using an average of the prior 7 days among the available days within the pre-specified window (For Week 24: Study Days 155 to 186), excluding the study day itself, if a value had been recorded by the participant on at least 4 of the prior 7 days; otherwise, the 7-day prior average for that study day was to be considered missing. One calculated (non-missing) 7-day prior average was selected for analysis according to the study day with nearest proximity to Week 24 (Study Day 168), with the earlier selected in the case of a tie. Baseline was defined as the (non-missing) 7-day interval ending on the latest day prior to randomization.
A serious adverse event was defined as any adverse event that met any of the following criteria: was fatal; was life-threatening; required or prolonged inpatient hospitalization; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to the study drug; or, was a significant medical event in the investigator's judgment. Multiple occurrences of the same serious adverse event in one individual were counted once.

The weekly itch severity score is the sum of the daily itch severity scores over 7 days and ranges from 0 to 21. The daily itch severity score is the average of the morning and evening scores on a scale of 0 (none) to 3 (severe). The Baseline weekly itch severity score is the sum of the daily itch severity scores over the 7 days prior to the first treatment. A higher itch severity score indicates more severe itching. A negative change score indicates improvement.
The percentage of participants with serious adverse events and other adverse events is summarized by MedDRA preferred terms and organ classes in the Reported Adverse Events section below.

A protocol-defined asthma exacerbation was defined as worsening of asthma symptoms requiring treatment with systemic corticosteroids for 3 or more days; for patients receiving long-term oral corticosteroids, an exacerbation was a 20 mg or more increase in average daily dose of oral prednisone (or a similar dose of another systemic corticosteroid). The rate of protocol-defined asthma exacerbations, normalized by subject-time at risk and computed over the 48 week treatment period in each treatment group.
To determine the efficacy of omalizumab injection in reducing the annualized rate of moderate or severe exacerbations (primary outcome) over the course of 12 months among individuals with COPD having sensitization and exposure to any of a panel of common indoor aeroallergens.
The UAS is a composite diary-recorded score, which is the sum of the numeric severity intensity ratings (0 = none to 3 = intense) for 1) the number of wheals (hives) and 2) the intensity of the pruritus (itch). The UAS7 is the sum of the daily average UAS (morning and evening values) for 7 days. The maximum UAS7 score is 42.
The primary analysis included two tests: a test for superiority of the lyophilized formulation of omalizumab compared with placebo in the change of allergen concentration and a test for the superiority of the aged liquid omalizumab compared with placebo. The difference for the change in the allergen concentration between the lyophilized formulation of omalizumab and placebo, and between the aged liquid omalizumab and placebo were assessed by the exact Wilcoxon-Mann-Whitney test.
All grades according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), v3.0. An SAE is defined as an adverse event that results in death, is life threatening, requires hospitalization, results in significant disability, results in birth defect, or is considered a significant medical event by the investigator

Omalizumab is studied in allergic asthma, chronic idiopathic urticaria, chronic obstructive pulmonary disease (COPD), nasal polyps, and peanut hypersensitivity. It is a monoclonal antibody developed by Roche Holding AG under the ticker RHHBY. The program is in Phase 2 development, and the clinical trials listed focus on COPD and chronic rhinosinusitis with nasal polyps.
Omalizumab targets IGHE, immunoglobulin E, and acts as an inhibitor of that target. By binding immunoglobulin E, the monoclonal antibody is designed to interfere with the IgE pathway that drives allergic responses. This mechanism underlies its study across allergic asthma, chronic idiopathic urticaria, nasal polyps, COPD, and peanut hypersensitivity.
Omalizumab is developed by Roche Holding AG, which trades under the ticker RHHBY. Roche is the company associated with the omalizumab program across its studied indications, including allergic asthma, chronic idiopathic urticaria, COPD, nasal polyps, and peanut hypersensitivity.
Omalizumab is in Phase 2 development. It is an investigational monoclonal antibody and is not described as approved. The program has four completed trials and one active trial, with a total enrollment of 2,749 participants across randomized, double-blind, placebo-controlled studies.
The active study is NCT07059091, a Phase 2 trial of omalizumab in allergen sensitized and exposed individuals with COPD, recruiting 334 participants in the United States. Completed trials include NCT03478930, NCT03280550, and NCT03280537, all Phase 3 studies in chronic rhinosinusitis with nasal polyps.
Yes, omalizumab is also known as Xolair. The names Xolair, Xolair (omalizumab), omalizumab (Xolair), and Omalizumab (Xolair) all refer to the same monoclonal antibody developed by Roche Holding AG. Searches for any of these names point to the same Phase 2 program.
