Study summary

A single-center, double-blind, placebo-controlled study of FDC olopatadine hydrochloride and mometasone furoate nasal spray (Molo; also referred as GSP 301) was conducted in subjects with seasonal allergic rhinitis. In this study, the efficacy and safety of two regimens (BID and QD) of the FDC (i.e. Molo 1 and Molo 2) were evaluated compared to placebo nasal spray, DYMISTA® and PATANASE®.

Inclusion criteria

  • Male and female patients aged 18 to 65 years (inclusive) with a clinical history of seasonal allergic rhinitis (SAR) (for at least 2 years) and exhibiting a positive skin prick test

Exclusion criteria

Exclusion Criteria:

  • Pregnant or lactating women
  • Patients with known to any of the components of the formulation
  • Patients with a history of seasonal asthma during ragweed season.
  • Patient requiring chronic use of inhaled or systemic
  • Patients with perennial rhinitis; non-allergic rhinitis; or ocular infection within 3 weeks before the screening
  • Patients with history of acute or significant chronic sinusitis or chronic purulent post-nasal drip or Rhinitis Medicamentosa as determined by the Investigator.
  • Patients with history of narrow-angle glaucoma, increased intraocular pressure, posterior subcapsular cataract, urinary retention, uncontrolled hypertension, severe Coronary Artery Disease, Ischemic Heart Disease, uncontrolled Diabetes Mellitus, Hyperthyroidism, Renal Impairment or Prostatic Hypertrophy, and those receiving MAO inhibitor therapy.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Change in mean post-treatment instantaneous Total Nasal Symptoms Score (iTNSS) for Molo 1 and Molo 2 compared with placebo from baseline to end of treatment

    Instantaneous Total Nasal Symptom Score (iTNSS) is calculated as the sum of instantaneous scoring of the severity of four individual nasal symptoms (nasal congestion, rhinorrhea, nasal itching, sneezing). Subject responds on a 4-point severity scale with scores ranging from 0 (no signs/absent) to 3 (severe signs).

    Time frame: 15 days

Secondary outcomes

  1. Change in mean post-treatment iTNSS for Molo 1 and Molo 2 compared with reference products Dymista and Patanase

    Instantaneous Total Nasal Symptom Score (iTNSS) is calculated as the sum of instantaneous scoring of the severity of four individual nasal symptoms (nasal congestion, rhinorrhea, nasal itching, sneezing). Subject responds on a 4-point severity scale with scores ranging from 0 (no signs/absent) to 3 (severe signs).

    Time frame: 15 days

  2. Change in mean post-treatment iTNSS for reference products Dymista and Patanase compared with placebo

    Instantaneous Total Nasal Symptom Score (iTNSS) is calculated as the sum of instantaneous scoring of the severity of four individual nasal symptoms (nasal congestion, rhinorrhea, nasal itching, sneezing). Subject responds on a 4-point severity scale with scores ranging from 0 (no signs/absent) to 3 (severe signs).

    Time frame: 15 days

  3. Onset of action assessed by comparing change in iTNSS after the first dose

    Time frame: 15 days

  4. Change from baseline in post-treatment instantaneous Total Symptoms Score (iTSS) (Molo 1 and Molo 2 versus Active Comparator)

    Instantaneous Total Symptom Score (iTSS) is calculated as the sum of the four individual nasal symptom (nasal congestion, rhinorrhea, nasal itching, sneezing) scores and the three individual ocular symptom (ocular itching, tearing/watering eyes, and ocular redness) scores. Subject responds on a 4-point severity scale with scores ranging from 0 (no signs/absent) to 3 (severe signs).

    Time frame: 15 days

  5. Change from baseline in individual instantaneous Nasal Symptoms Scores (iNSS) (Molo 1 and Molo 2 versus Active Comparator)

    Individual Instantaneous Nasal Symptoms Scores (iNSS) is calculated as the score of individual nasal symptoms (nasal congestion, rhinorrhea, nasal itching, sneezing). Subject responds on a 4-point severity scale with scores ranging from 0 (no signs/absent) to 3 (severe signs).

    Time frame: 15 days

  6. Change from baseline in instantaneous Total Ocular Symptom Score (iTOSS) (Molo 1 and Molo 2 versus Active Comparator)

    Instantaneous Total Ocular Symptom Score (iTOSS) is calculated as the sum of the three individual ocular symptoms (ocular itching, tearing/watering eyes, and ocular redness). Subject responds on a 4-point severity scale with scores ranging from 0 (no signs/absent) to 3 (severe signs).

    Time frame: 15 days

  7. Change in mean post-treatment Environmental Exposure Chamber - Rhinoconjunctivitis Quality-of-Life Questionnaire (EEC-QoLQ) scores

    The EEC-QoLQ has questions in three domains (non-nose/eye symptoms, practical problems and emotional) related to how much a subject was bothered with symptoms. Subject responds on a 7-point scale with score ranging from 0 (better outcome) to 6 (worse outcome).

    Time frame: 15 days

  8. Responses to a reflective Global Assessment of Tolerability and Acceptance Questionnaire (GATAQ)

    Scale of 0 (very much acceptable) - 6 (not acceptable)

    Time frame: 15 days

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2014 to primary completion in Feb 2014, 1 month.

Of 24 phase 2 interventional studies under Rhinitis, Allergic, Seasonal, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 23. This study's 1 month is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 20, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
