Trial Outcomes & Findings for A Study of the Safety and Immune Response to RotaTeq™ Vaccine in the Elderly (V260-027) (NCT NCT00836498)

NCT ID: NCT00836498

Last Updated: 2015-05-01

Results Overview

All randomized participants were contacted via telephone or in-center visit on Days 7, 14, 28, and 42 after each dose. Participants received a Vaccination Report Card (VRC) at each vaccination visit as well as instructions for recording AEs. Participants were also instructed to record potential acute gastroenteritis episodes (AGEs) that occurred within 42 days after any dose on the report card.

PRIMARY outcome

Timeframe: Up to 42 days following any dose of RotaTeq™ or placebo

Population: All randomized participants who received at least one dose of RotaTeq™ or placebo are included in the summaries. Number of participants with one or more adverse experience.

All randomized participants were contacted via telephone or in-center visit on Days 7, 14, 28, and 42 after each dose. Participants received a Vaccination Report Card (VRC) at each vaccination visit as well as instructions for recording AEs. Participants were also instructed to record potential acute gastroenteritis episodes (AGEs) that occurred within 42 days after any dose on the report card.

PRIMARY outcome

Timeframe: Up to 180 days following the third dose of RotaTeq™ or placebo

Population: All randomized participants who received at least one dose of RotaTeq™ or placebo are included in the summaries. Number of participants with one or more adverse experience.

All randomized participants were contacted via telephone or in-center visit on Days 7, 14, 28, and 42 after each dose. Participants received a Vaccination Report Card (VRC) at each vaccination visit as well as instructions for recording AEs. Participants were also instructed to record potential acute gastroenteritis episodes (AGEs) that occurred within 42 days after any dose on the report card. SAEs were followed by passive surveillance (in which either participants self reported or information was collected at participants' last visit) for 180 days following the final dose.
