Omalizumab Before Onset of Exacerbations
(OBOE)
What this study is about
OBOE is a forward-looking, pilot, parallel group RCT with the overall aim of examining the effect of a single dose of anti-IgE (omalizumab) vs. placebo administered at the onset of URIs in the fall season among highly exacerbation-prone, urban, and atopic youth aged 6-17 years with persistent asthma. OBOE will recruit and randomize participants over 3 years (3 annual cohorts of participants).
View original scientific description
OBOE is a prospective, pilot, parallel group RCT with the overall aim of examining the effect of a single dose of anti-IgE (omalizumab) vs. placebo administered at the onset of URIs in the fall season among highly exacerbation-prone, urban, and atopic youth aged 6-17 years with persistent asthma. OBOE will recruit and randomize participants over 3 years (3 annual cohorts of participants). Recruitment for each of the yearly cohorts of OBOE will begin in February. Each cohort will be followed for a 2-6-month run-in period with the objective to gain control of each participant's asthma and to stabilize the required controller medication step level. Participants will receive routine asthma care every 1-2 months (a total of 2-4 times) during run-in using a previously described algorithm developed by the Inner-city Asthma Consortium and successfully employed in the PROSE study. The primary outcome is the change in the amount of nasal IFN-α recovered by nasal fluid absorption between two time points, within 72 hours of onset of a URI as defined by onset of (or substantial worsening of) rhinorrhea, nasal congestion or sneezing (single or multiple symptoms) and 3-6 days after study drug injection.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

- Have a negative rapid nasal swab antigen test for SARS-CoV-2
- Be more than 14 days from the onset of any previous asthma exacerbation requiring systemic steroids
- Have no current lower respiratory symptoms that, in the opinion of the study physician, require systemic corticosteroid treatment
- Complete collection of nasal absorption sample within 72 hours of onset URI \[defined by onset of (or substantial worsening of) rhinorrhea, nasal congestion or sneezing (single or multiple symptoms)\] as determined by the study physician's assessment at the SVa visit
Exclusion criteria
- Inability or unwillingness of a participant's parent or guardian to give written informed consent or comply with study protocol or inability or unwillingness of a participant ≥7 to provide assent
- Contraindication to receipt of omalizumab
- Presence of a second chronic medical condition (including but not limited to serious cardiorespiratory disorders, cancer, sickle cell disease, uncontrolled seizure disorder, auto-immune disorders, or type 1 diabetes)
- Pregnancy or active lactation
- History of latex allergy
- Treatment with omalizumab or other monoclonal antibody, or aeroallergen immunotherapy in the prior six months

- History of life-threatening asthma defined by requirement for intubation or cardiorespiratory arrest
- Inability of primary caregiver and child to speak English
- In the opinion of the investigator, participant will not be able to wean from nasal steroids or to avoid nasal vaccinations during the 90-day fall outcome period
- Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
