Trial Outcomes & Findings for Safety Study of Ragweed Allergy Immunotherapy Tablet in Subjects 50 Years of Age and Older (Study P06081) (NCT NCT00978029)

NCT ID: NCT00978029

Last Updated: 2017-03-03

Results Overview

Participants were treated for 28 days with either 6 or 12 Units of SCH 39641 or placebo, and the proportion 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.

PRIMARY outcome

Timeframe: Up to Day 42

Population: All subjects as treated (ASAT) consisting of all randomized participants who received at least one dose of study treatment. Due to non-compliance with GCP 7 participants were excluded from this analysis.
