A 28-Day Study Evaluating the Safety of Ragweed (Ambrosia Artemisiifolia) Allergy Immunotherapy Tablet (SCH 39641/MK-3641) Treatment in Ragweed Allergic Adults (Phase 3, Protocol No.P05751)

This study assessed the safety profile of short ragweed (Ambrosia artemisiifolia) in participants with ragweed-induced rhinoconjunctivitis with or without asthma.

Åtgärdsbeskrivning
Tidsram
Number of Participants With Treatment-emergent Adverse Events (AEs)
Tidsram: 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.
Up to Day 35
