NCT02320396

Brief Summary

This is an efficacy and safety study of desloratadine (MK-4117) in Japanese participants with seasonal allergic rhinitis (SAR). The primary hypothesis of this study is that the change from Baseline in Total Nasal Symptom Score (TNSS) is improved by desloratadine compared to placebo.

Outcome Measures

Primary Outcomes (3)

  • Change From Baseline in Total Nasal Symptom Score (TNSS) During 2 Weeks of Therapy

    The TNSS was used to evaluate participant nasal symptoms of: sneezing (daily frequency of attacks scored from 0 \[\<1 time or "none"\] to 4 \[≥21 times\]), rhinorrhea (daily frequency of blowing nose scored from 0 \[\<1 time or "none"\] to 4 \[≥21 times\]), nasal congestion (scored from 0 \[no nasal blockage\] to 4 \[completely obstructed all day\]), and nasal itching (scored from 0 \[none\] to 4 \[nose is itchy, requiring frequent rubbing or blowing nose) as rated in the participant's diary. The TNSS was the sum of the 4 nasal symptom sub-scores. TNSS scores ranged from 0 to 16, with a higher score indicating more frequent/severe nasal symptoms. Baseline (BL) measurement was an average of scores for 3 days prior to treatment (during Confirmation of Symptom Period). Post-BL measurement was an average from Day 1 to Day 13 (2 week average). Change from BL = Post BL measurement - BL measurement.

    Baseline, Day 1 to Day 13 (Weeks 1 through 2 average) of double-blind treatment

  • Number of Participants Who Experience at Least One Adverse Event (AE)

    An AE was defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that was temporally associated with the use of the Sponsor's product, was also an AE.

    Up to 4 weeks (Up to 2 weeks after last dose of study drug)

  • Number of Participants Who Discontinue Study Drug Due to an AE

    An AE was defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that was temporally associated with the use of the Sponsor's product, was also an AE.

    Up to 2 weeks

Secondary Outcomes (10)

  • Change From Baseline in TNSS for Week 1 and Week 2 of Double-blind Treatment

    Baseline, Day 1 to 7 (Week 1 average), Day 8 to 13 (Week 2 average) of double-blind treatment

  • Change From Baseline to Week 1 in Each Nasal Symptom Sub-Score (Sneezing, Rhinorrhea, Nasal Congestion and Nasal Itching)

    Baseline, Day 1 to 7 (Week 1 average) of double-blind treatment

  • Change From Baseline to Week 2 in Each Nasal Symptom Sub-Score (Sneezing, Rhinorrhea, Nasal Congestion and Nasal Itching)

    Baseline, Day 8 to 13 (Week 2 average) of double-blind treatment

  • Change From Baseline in Each Nasal Symptom Sub-Score (Sneezing, Rhinorrhea, Nasal Congestion and Nasal Itching) During 2 Weeks of Therapy

    Baseline, Day 1 to Day 13 (Weeks 1 through 2 average)

  • Change From Baseline to Week 1 in Eye Symptoms (Pruritus, Watering Eyes and the Worse One of Either Pruritus or Watering Eyes)

    Baseline, Day 1 to 7 (Week 1 average) of double-blind treatment

  • +5 more secondary outcomes

Study Arms (2)

Desloratadine

EXPERIMENTAL

After a 1-week single-blinded placebo run-in during which SAR symptoms are confirmed (Confirmation of Symptom Period), participants receive double-blinded desloratadine (one 5 mg tablet) orally (PO) once daily (QD) in the morning for 2 weeks during the Treatment Period.

Drug: Desloratadine 5 mg

Placebo

PLACEBO COMPARATOR

After a 1-week single-blinded placebo run-in during which SAR symptoms are confirmed (Confirmation of Symptom Period), participants receive double-blinded placebo (one tablet) PO QD in the morning for 2 weeks during the Treatment Period.

Drug: Placebo

Interventions

Desloratadine 5 mg tablets

Desloratadine

Placebo tablets
