What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
OmalizumabDrug
Omalizumab were administered by subcutaneous injection. Dose (75 to 600 mg) and dosing frequency (every 2 or 4 weeks) were determined by serum total IgE level (IU/mL) and body weight (kg) measured at the screening epoch according the dosing table.
PlaceboDrug
Placebo were administered by subcutaneous injection. Dose (75 to 600 mg) and dosing frequency (every 2 or 4 weeks) were determined by serum total IgE level (IU/mL) and body weight (kg) measured at the screening epoch according the dosing table.
| Study group | Role | What they receive |
|---|---|---|
| Omalizumab | Experimental | Eligible patients randomized to this arm received omalizumab subcutaneously for 12 weeks Receives: Drug: Omalizumab |
| Placebo | Placebo comparator | Eligible patients randomized to this arm received placebo subcutaneously for 12 weeks Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Nasal Symptom Score
Nasal symptoms (sneezing, rhinorrhea and nasal congestion) were recorded by the patient everyday in their e-Diary, on a scale of 0 (none) to 4 (intense/severe). Nasal symptom score (0-12 point) consisted of score for severity of sneezing (0-4 point), rhinorrhea (0-4 point) and nasal congestion (0-4 point).
Severe symptom period: The three weeks where the cumulative value of the mean daily nasal symptom score is the maximum. The three weeks must also meet one of the following criteria: 2) ≥ 70% of the period with concomitant use of fluticasone propionate is included in this three weeks. 2) ≥ 70% of this three weeks includes the period with concomitant use of fluticasone propionate. If not, severe symptom period was extended at a minimum to meet one of the criteria above. The severe symptom period will be defined as: the three weeks where the cumulative value of the mean daily nasal symptom score will be the maximum.
Measured: Severe symptom period (from 23Feb2018 to 24March2018)
Secondary outcomes (14)
Mean Ocular Symptom Score and Mean Nasal Ocular Symptom Score

Nasal ocular symptom score consisted of nasal symptom score and ocular symptom score.
Nasal ocular symptom score is the sum of nasal symptom score (0-12) and ocular symptom score (0-8) 0 presents no nasal ocular symptom and 20 presents worse outcome.
Measured: Severe symptom period (from 23Feb2018 to 24Mar2018)

Nasal symptom medication score is the sum of nasal symptom score and medication score (fexofenadine hydrochloride, fluticasone propionate, tramazoline hydrochloride) Ocular symptom medication score is the sum of ocular symptom score and medication score (fexofenadine hydrochloride, levocabastine hydrochloride) Nasal ocular symptom medication score is the sum of nasal symptom score, ocular symptom score and medication score (fexofenadine hydrochloride, fluticasone propionate, tramazoline hydrochloride, levocabastine hydrochloride).
Measured: Severe symptom period (from 23Feb2018 to 24Mar2018)
Mean Score for Severity of Sneezing, Rhinorrhea and Nasal Congestion
Symptoms of sneezing, rhinorrhea and nasal congestion were evaluated on a scale of 0 (none) to 4 (intense/severe).
Measured: Severe symptom period (from 23Feb2018 to 24Mar2018)
Mean Score for Severity of Itchy and Watery Eye
Symptoms of itchy and watery eye were evaluated on a scale of 0 (none) to 4 (intense/severe).
Measured: Severe symptom period (from 23Feb2018 to 24Mar2018)
Mean Score for Impairment of Daily Activities
Impairment of daily activities were evaluated on a scale of 0 (none) to 4 (intense/severe).
Measured: Severe symptom period (from 23Feb2018 to 24Mar2018)
Number of Symptom Free Days
Nasal symptom free days (days with all nasal symptoms are not more than mild in severity) during the severe symptom period. Ocular symptom free days (days with all ocular symptoms are not more than mild in severity) during the severe symptom period.
Measured: Severe symptom period (from 23Feb2018 to 24March2018)
Completely Nasal Symptom Free Patients
Completely nasal symptom free patients is the number of patients who were nasal symptom free (all nasal symptoms were not more than mild in severity) on all non-missing days and had nasal symptom scores for at least 26 days during the 30 days of severe symptom period.
Measured: Severe symptom period (from 23Feb2018 to 24Mar2018)
Rescue Medication Score
Rescue medication scores were given for tramazoline hydrochloride (nasal, 1 point) and levocabastine hydrochloride (ocular, 1 point).
Rescue medication score for nasal is medication score for Tramazoline hydrochloride, Rescue medication score for ocular is medication score for Levocabastine hydrochloride and Rescue medication score for nasal and ocular is the sum of medication score for Tramazoline hydrochloride and Levocabastine hydrochlorid
Measured: Severe symptom period (from 23Feb2018 to 24Mar2018)
Rescue Medication Free Days
Number of days with no rescue medication (tramazoline hydrochloride, levocabastine hydrochloride).

Japanese Rhinoconjunctivitis Quality of Life Questionnaire (JRQLQ, No1) Score
Nasal and eye symptoms (JRQLQ I) included 6 categories: Runny nose, Sneezing, Nasal congestion, Itchy nose, itchy eyes and watery eyes, on a 5-point scale of 0 to 4 (no symptoms to very severe symptoms). JRQLQ I score was a mean of these 6 categories. JRQLQ II included 17 items on a 5-point scale, 0 to 4 (no significant problem to very greatly). JRQLQ II scores was a mean of these 17 items. Overall face scale (JRQLQ III) evaluated overall symptoms, condition and feelings on a 5-point scale from 0 to 4 (fine to crying). Evaluation visit was defined as follows independently for each evaluation item and for each patient: 1) If there was a single visit during the severe symptom period, the visit was the evaluation visit. 2) If there were ≥ 2 visits during the severe symptom period and a) if Visit 105 was one of them, Visit 105 was the evaluation visit; b) if Visit 105 was outside the period, the closest visit to Visit 105 during the period was the evaluation visit.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Omalizumab in people with Seasonal Allergic Rhinitis, run by Novartis Pharmaceuticals at 22 sites in Japan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 22 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 Nov 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean Nasal Symptom Score (time frame: Severe symptom period (from 23Feb2018 to 24March2018)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2026.
