According to the results reported on ClinicalTrials.gov, this trial (NCT01066104) enrolled 27 people in total — 14 in the placebo group and 13 in the Xolair (omalizumab) group. Of those, 12 people in each group finished the study. The trial was looking at whether Xolair had any effect on nasal polyps and thickened tissue in the sinuses, measured in two ways: CT scans of the sinuses and a visual examination of the nose using a small camera (rhinoscopy). The reported data shows the following numbers for the CT scan measurement (the primary outcome), expressed as percentage change in the amount of thickened tissue in the sinuses: the placebo group showed an average change of −8.9% (a decrease), while the Xolair group showed an average change of +4.2% (an increase). For the secondary outcome — a visual scoring of nasal polyp size on a scale from 0 (no polyps) to 8 (most severe) — the reported average change in score was +0.05 in the placebo group (roughly no change) and −0.33 in the Xolair group (a small decrease). These numbers describe the average shifts across each group over the course of the study. It is worth noting that this was a relatively small trial with just over a dozen participants in each group, so the reported figures reflect a limited number of people. No data was reported for any other outcome measures beyond these two. These are the results as reported to ClinicalTrials.gov.

- You must have been diagnosed with chronic rhinosinusitis (long-term sinus disease), meaning you have had at least two major symptoms — such as facial pain/pressure, headaches, nasal congestion, nasal drainage, or reduced/lost sense of smell — for at least 3 months in a row.
- You must have an abnormal sinus scan or camera examination showing sinus disease in at least two sinus areas, documented within 3 months of joining.
- You must have nasal polyps (small growths in the nose) or swollen nasal tissue on both sides of your nose, visible in specific sinus areas, with a minimum polyp score of 4 on a nasal examination.
- You must have a confirmed or past history of allergy to a year-round airborne allergen (such as dust mites or pet dander), shown by a skin test or blood test.
- Your blood IgE level (an allergy-related protein) must be between 30 and 1500 IU/mL, and your body weight must be between 30 and 150 kg (about 66–330 lbs), to match the study medication dosing requirements.
- Your symptom score at the start of the study must be at least 5 out of 15.
Who may not be able to join:
- Women who are pregnant, breastfeeding, or of childbearing age and not using an approved form of birth control.
- People who do not meet the medical requirements for the study drug, Xolair (omalizumab) (confirm with trial site).
- People who are currently taking a beta-blocker medication (a type of heart or blood pressure medicine).
- People who have a known allergy or sensitivity to Xolair (omalizumab).
- People who currently have an active bacterial sinus infection with visible pus on examination or an untreated fluid/air pocket seen on a sinus scan.
- People who have taken antibiotics within 3 weeks before the screening visit.
- People with poorly controlled moderate-to-severe asthma who needed a course of steroid tablets within 6 weeks of joining the study (those on a very low daily maintenance dose of Prednisone of 5 mg or less may still be eligible, as long as the dose stays the same during the study).
- People who have had repeated, uncontrolled nosebleeds within the past 6 weeks.
- People with a history of certain conditions, including low antibody levels in the blood, cystic fibrosis, bronchiectasis, immotile cilia syndrome, a systemic granulomatous disease, cancer or a strong family history of cancer, or recent cocaine use.
- People who have smoked cigarettes within the past 3 years.
- People with serious heart problems, uncontrolled diabetes, chronic kidney or liver disease, HIV, or other active uncontrolled infections, or who have had major surgery within 3 months of the screening visit.
- People who have a significant history of not following medical treatment plans, or who are unable to give informed consent.
- People with alcohol or drug abuse or dependence within the past 3 months.
- People with significantly abnormal liver, kidney, or blood test results (confirm with trial site for specific values).
- People who have taken an oral or systemic steroid burst (a short high-dose course of steroids) within 6 weeks of joining the study.
- People who have taken part in another clinical trial or used any other experimental medication within the 30 days before enrolling.
