Group Intervention Description SCH 39641 12 Amb a 1-U SCH 39641 12 Units short ragweed (Ambrosia artemisiifolia) Major Allergen 1 (Amb a 1-U) extract in an AIT, sublingual, once daily. Placebo Placebo for SCH 39641 Matching placebo tablet, sublingual, once daily.
- Primary Outcome Measures
Name Time Method Number of Participants With Treatment-emergent Adverse Events (AEs) Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with treatment-emergent AEs were recorded. An AE is any unfavorable and unintended sign, symptom or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product. Treatment-emergent AEs are new AEs that occur after participants have been randomized into the trial, or existing AEs that occurred during Screening that increase in severity after randomization.
- Secondary Outcome Measures
Name Time Method Number of Participants Reporting Oral Pruritus. Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with oral pruritus were recorded. All AEs, combining non-treatment-emergent AEs with treatment-emergent AEs, were reported.
Number of Participants Reporting Mouth Oedema Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with mouth oedema were recorded. All AEs, combining non-treatment-emergent AEs with treatment-emergent AEs, were reported.
Number of Participants Reporting Nasal Passage Irritation Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with nasal passage irritation were recorded. All AEs, combining non-treatment-emergent AEs with treatment-emergent AEs, were reported.
Number of Participants Reporting Skin Pruritus Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with skin pruritus were recorded. All AEs, combining non-treatment-emergent AEs with treatment-emergent AEs, were reported.
Number of Participants Reporting Throat Irritation Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with throat irritation were recorded. All AEs, combining non-treatment-emergent AEs with treatment-emergent AEs, were reported.
Number of Participants Reporting Eye Pruritus Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with eye pruritus were recorded. All AEs, combining non-treatment-emergent AEs with treatment-emergent AEs, were reported.
Number of Participants Reporting Ear Pruritus Up to Day 35 Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with ear pruritus were recorded. All AEs, combining non-treatment-emergent AEs with treatment-emergent AEs, were reported.
Number of Participants Who Discontinued Due to Treatment-emergent AEs Up to Day 28 Participants were treated with either SCH 39641 12 Amb a 1-U or placebo for 28 days, and the number who discontinued due to treatment emergent-AEs were recorded. An AE is any unfavorable and unintended sign, symptom or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product. Treatment-emergent AEs are new AEs that occur after participants have been randomized into the trial, or existing AEs that occurred during Screening that increase in severity after randomization.
