Participants will:

  • Take DEP114 or desloratadine once daily for 5 days (up to a maximum of 7 days).
  • Keep a diary of their symptoms.

Terms in these criteria, in plain language(5)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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.

What researchers measure

Primary outcomes

  1. Absolute change in the Total Nasal Symptom Score (TNSS) for nasal congestion, rhinorrhea, nasal itching, and sneezing, measured 5 days after treatment initiation (TNSS₀-₅).

    The Total Nasal Symptom Score (TNSS) is the sum of the severity scores for each nasal symptom assessed (nasal congestion, rhinorrhea, nasal itching, and sneezing) over the previous 24 hours. The severity of each symptom is evaluated using a 4-point categorical scale (0 = absent, 1 = mild, 2 = moderate, and 3 = severe). The total score ranges from 0 to 12 points, with higher scores indicating more severe nasal symptoms and a worse clinical condition. Negative changes from baseline indicate improvement in symptoms.

    Time frame: Day 5 after treatment initiation

Secondary outcomes

  1. Overall improvement of nasal symptoms throughout the treatment period.

    Absolute change in the Total Nasal Symptom Score (TNSS) on treatment Days 1, 2, 3, 4, and 5 (TNSS₀-₁, TNSS₀-₂, ..., TNSS₀-₅).

    Time frame: Day 5 after treatment initiation

  2. Overall improvement of nasal symptoms 3 days after treatment initiation.

    Proportion of participants with improvement in the Total Nasal Symptom Score (TNSS) at Day 3 after treatment initiation, where improvement is defined as a reduction of at least 4 points from baseline. TNSS ranges from 0 to 12 points, with higher scores indicating more severe nasal symptoms and a worse clinical condition; therefore, a decrease in TNSS represents clinical improvement.

    Time frame: Day 3 after treatment initiation

  3. Change From Baseline in Nasal Congestion Severity Assessed by the Nasal Congestion Severity Score (NCSS) Throughout the Treatment Period

    Absolute change from baseline in the Nasal Congestion Severity Score (NCSS) on treatment Days 1, 2, 3, 4, and 5. NCSS ranges from 0 to 3 points, where higher scores indicate more severe nasal congestion and a worse clinical condition. Negative changes from baseline indicate improvement.

    Time frame: From treatment initiation through Day 5 of treatment

  4. Distribution of Participants by Rhinorrhea Severity Category Using the TNSS Rhinorrhea Item at Days 3 and 5

    Distribution of participants according to rhinorrhea severity categories based on the rhinorrhea item of the Total Nasal Symptom Score (TNSS), assessed at Days 3 and 5 after treatment initiation.

    Time frame: 3 and 5 days after treatment initiation

  5. Improvement in Nasal Itching Severity Assessed by the Total Nasal Symptom Score (TNSS) at Days 3 and 5 After Treatment Initiation

    Distribution of participants according to nasal itching severity assessed using the nasal itching item of the Total Nasal Symptom Score (TNSS) at Days 3 and 5 after treatment initiation.

    Time frame: Day 3 and Day 5 after treatment initiation

  6. Improvement in Sneezing Severity Assessed by the Total Nasal Symptom Score (TNSS) at Days 3 and 5 After Treatment Initiation

    Distribution of participants according to sneezing severity assessed using the sneezing item of the Total Nasal Symptom Score (TNSS) at Days 3 and 5 after treatment initiation.

    Time frame: Day 3 and Day 5 after treatment initiation

  7. Global Assessment of Treatment by the Participant's Caregiver at Day 5 After Treatment Initiation

    Distribution of participants according to the categories of the caregiver's global assessment of treatment scale: 0 = very poor, 1 = poor, 2 = neither good nor poor, 3 = good, and 4 = very good.

    Time frame: Day 5 after treatment initiation

  8. Investigator Global Assessment of Treatment at Day 5

    Distribution of participants according to the investigator's global assessment of treatment score categories (0 = very poor, 1 = poor, 2 = neither good nor poor, 3 = good, and 4 = very good).

    Time frame: Day 5 after treatment initiation

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

Start is estimated for Jun 2027; primary completion for Dec 2028, 18 months later.

Of 31 industry-sponsored phase 3 interventional studies under Rhinitis, Allergic, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 41. This study's planned 18 months is above that.

Counting every sponsor, half of 41 studies reached it within 13 months; a quarter within 6 and three quarters within 35.

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 Sep 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
