All Clinical Trials for INFANRIX

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00370318 ↗	Prophylactic Antipyretic Treatment in Children Receiving Pneumococcal Conjugate and Standard Infant Vaccines	Completed	GlaxoSmithKline	Phase 3	2006-09-01	The purpose of this trial is to assess if the rate of febrile reactions following the co-administration of pneumococcal conjugate vaccines with standard infant vaccines is lowered when paracetamol is given prophylactically.
NCT00496015 ↗	Prophylactic Antipyretic Treatment in Children Receiving Booster Dose of Pneumococcal Conjugate Vaccine GSK1024850A	Completed	GlaxoSmithKline	Phase 3	2007-07-02	The purpose of this trial is to assess if the rate of febrile reactions following the co-administration of a booster dose of pneumococcal conjugate vaccines with standard infant vaccines is lowered when paracetamol is given prophylactically and to assess the impact of pneumococcal conjugate vaccine on pneumococcal and H. influenzae nasopharyngeal carriage compared to control group receiving meningococcal conjugate vaccine (GSK134612). This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00370318).
NCT01392378 ↗	Study Assessing the Effect of Medications to Prevent Fever on Prevenar 13®	Completed	Pfizer	Phase 4	2011-08-01	The purposes of this study are assess the immunological response (measure the amount of antibodies, i.e. proteins that fight off germs) produced by children after they have been given the 13-valent pneumococcal vaccine (13vPnC) and INFANRIX hexa at 2, 3, 4 and 12 months of age when medications to prevent fever are given on the same day as the vaccination. Also to evaluate the safety of 13-valent pneumococcal conjugate vaccine (13vPnC) in children who receive medications to prevent fever on the day of vaccination.
NCT02422264 ↗	Immunogenicity and Safety Study of Infanrix Hexa in Healthy Infants Born to Mothers Vaccinated With Boostrix™ During Pregnancy or Immediately Post-delivery	Completed	GlaxoSmithKline	Phase 4	2016-01-22	The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' Infanrix hexa, given in the primary vaccination schedule to infants born to pregnant women who participated in study 116945 [DTPA (BOOSTRIX)-047]. This study will help us evaluate if the presence of transplacentally transferred maternal antibodies interfere with the immune response to primary vaccination with Infanrix hexa and a co-administered pneumococcal conjugate vaccine given as a part of this study in infants.
NCT05073003 ↗	A Study on the Safety and Immune Responses to the GVGH altSonflex1-2-3 Vaccine Against Shigellosis in Adults, Children, and Infants	Recruiting	GlaxoSmithKline	Phase 1/Phase 2	2021-10-06	The aim of the current clinical study is to evaluate, for the first time in humans (FTIH), the safety and immunogenicity of the altSonflex1-2-3 candidate vaccine against S. sonnei and S. flexneri serotypes 1b, 2a, and 3a. The vaccine will be first administered in adults 18 to 50 years of age in Europe. Subsequently, the vaccine will be administered to a shigellosis-endemic population in Africa, first in adults 18 to 50 years of age, then in children 24 to 59 months of age, and finally in infants 9 months of age. Infants will also receive a third vaccination. Three different doses of the vaccine [low (Dose A), medium (Dose B), and high (Dose C) amounts of antigen] will be evaluated using an age de-escalation approach (from least vulnerable adult population to most vulnerable paediatric population). The results of this study will allow the selection of the most appropriate dose for further vaccine development in infants 9 months of age, which is the main target age group for this vaccine.
