Efficacy of GSK Biologicals' Candidate Malaria Vaccine 257049 Against Malaria Disease in Infants and Children in Africa

NCT ID: NCT00866619

Last Updated: 2019-10-09

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 15459 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2009-03-27
• Study Completion Date: 2014-01-31

Brief Summary

The purpose of this observer-blind study is to gather key efficacy, safety, and immunogenicity information on GSK's candidate malaria vaccine in infants and children.

Detailed Description

The protocol posting document has been updated due to a protocol amendment dated 23 January 2012. An analysis time point has been added at Month 20. No changes have been made to the protocol endpoints or statistical methods but protocol endpoints will be analysed on data collected up to Month 20 once these data are available. The rationale is to have the full scope of protocol defined efficacy and safety endpoints related to a primary schedule without booster in both age categories followed up for 20 months earlier than at the initially planned study end time point (Visit 34 or Month 32 time point).

The protocol posting document was updated due to a protocol amendment dated 10 December 2010 to extend the study until December 2013 for all enrolled subjects (interval: Nov 2013-Jan 2014). Including the extension, the mean follow-up time for subjects from 5-17 months will be during 49 months post dose 1 (range: 41-55), while for subjects from 6-12 weeks, it will be during 41 months post dose 1 (range: 32-48). This study is double-blind during the first part and single-blind during the extension part. An analysis will be conducted at the end of the extension including an evaluation of safety and efficacy against clinical malaria, severe malaria and prevalent parasitemia.

The protocol posting document has been updated following the posting of results of the study (January 2015): The study remained double-blind until the end of the extension phase, and the analyses of Month 32 (initial end of study now becoming end of the first part of the study or primary study phase) and of the extension phase were conducted together.
