Respiratory Tract Infections Clinical Trial
Official title:
Oral Bacterial Lysate to Prevent Persistent Wheeze in Infants After Severe Bronchiolitis; a Randomised Placebo-controlled Trial
Bronchiolitis is a common viral infection of the small airways of infants and some affected infants will require hospital admission. Severe bronchiolitis is a marker for greatly increased risk of developing both preschool wheeze and subsequent school age asthma. Since epidemiological studies suggest that exposure to microbial products protects against preschool wheeze, lysates of bacteria may prevent the development of wheeze after bronchiolitis, with long-term beneficial consequences. BLIPA is a phase 2b, randomised, double blind, placebo-controlled study, investigating the efficacy superiority of bacterial lysate (Broncho Vaxom) capsules over placebo, in reducing wheeze in infants after severe bronchiolitis. The primary end point of the study is parent-reported, healthcare-professional confirmed wheeze at 19-24 months. The study aims to test bacterial lysate capsules (3.5mg over 24 months) for safety, efficacy, and to advance mechanistic understanding of its action.
The BLIPA study aims to investigate the following research questions: 1. In children hospitalised with bronchiolitis, does oral Broncho Vaxom (BV) given for 10 days per month for a total of 24 months, prevent parent-reported, healthcare professional-confirmed, wheeze between 19 and 24 months post initiation of IMP/placebo. 2. Does oral BV reduces the risk of wheeze after bronchiolitis by modulating T cell and Dendritic cells (DC) maturation and altering the gut and airway microbiota. (mechanistic hypothesis) The BLIPA study will combine the results of two multi-centre, randomised trials with similar but separate protocols: BLIPA-United Kingdom (UK), with recruitment in London, Southampton, Edinburgh, and Aberdeen and BLIPA-Australia, with recruitment in Brisbane, Gold Coast, Melbourne, Darwin and Sydney. BLIPA-UK is funded in the UK by the NIHR (National Institute for Health and Care Research). BLIPA-Australia is funded in Australia by the International Clinical Trial Collaboration (ICTC). ICTC supports Australian researchers to conduct clinical trial research in collaboration with international researchers. The total study duration is 54 months. The primary clinical objective is to recruit a population of eligible participants, to randomise them to oral Broncho Vaxom (3.5mg) or placebo, to be taken daily for 10 days a month over 24 months, follow up for 24 months and compare primary and secondary outcomes between trial arms. Parents or guardians of children, clinicians involved in their care and trial staff will be blinded to the treatment arm. Recruitment will be for 18 months and children's outcomes will be assessed for 24 months following initiation of Investigational Medicinal Product (IMP) or placebo. Within six weeks of hospital discharge following admission for bronchiolitis, parents or guardians can consent to their child partaking in the study, baseline data is collected, the child is randomised, and the IMP or placebo is initiated (12 months' supply). From the point of treatment initiation, children are followed up for 24 months, the same length as the treatment period. There will be at least one scheduled face to face visit at 12 months to dispense a further year's supply of IMP or placebo. ;
