Clinical and Biological Effects of Anti-IgE (Omalizumab) in Patients With Bilateral Nasal Polyposis and Asthma
Belgium23 participantsStarted 2006-12
Plain-language summary
This pilot study is a double-blinded, randomized controlled, two-centre trial in which subjects will receive 4 to 8 (subcutaneous administered) doses of medication (Omalizumab or placebo) (dose and dosing interval calculated on body weight and baseline total serum IgE). During the treatment period and follow-up, the clinical efficacy of the treatment will be assessed by evaluation of symptoms, Quality of Life questionnaire, morning Peak Expiratory Flow measurement, smell test, nasal endoscopy, CT-scan, peak nasal inspiratory flow and spirometry. Biological activity will be evaluated by measuring peripheral and local (in serum, in nasal secretions, biopsies) markers of inflammation.
Study hypothesis
1. Evaluation of the efficacy and safety of anti-IgE (Omalizumab) in patients with nasal polyposis and comorbid asthma.
2. Exploration of anti-IgE effects on local and systemic metabolism of IgE in nasal polyposis
3. Clinical assessment of the IgE theory in the pathogenesis of nasal polyps

Inclusion Criteria:
* Subjects must be at least 18 years of age, of either gender and any race.
* Subjects must have a diagnosis of bilateral nasal polyps at screening and baseline that have recurred after surgical resection or nasal polyps that are grades 3 or 4 in both nares using the scoring system described in table 5. Bilateral nasal polyposis is defined as sinus symptoms for more than 3 months, bilateral opacity on CT-scan imaging and visible nasal polyps at endoscopy.
Subjects must have a diagnosis of asthma for more than 2 years. Subjects must be in good health, free of any clinically significant disease that would interfere with the study schedule or procedures or compromise his/her safety.
* Subjects must be willing to give informed consent and adhere to visit schedules, medication restrictions, and agree to perform daily diary entries.
* Subjects must be free of any upper respiratory tract infection within two weeks prior to inclusion.
* Clinical laboratory tests must be within normal limits or clinically acceptable for the investigator.
* Non-pregnant women of childbearing potential must use a medically acceptable, adequate form of birth control. This includes: a) hormonal contraceptive as prescribed by a physician (eg, oral combined, hormonal implant, depot injectable); b) medically prescribed Intra-Uterine Device (IUD); c) condom in combination with a spermicide; d) monogamous relationship with a male partner who has had a vasectomy or is using a condom plus …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
