Could early markers unlock treatments for a rare childhood disease?
NCT ID NCT07709728
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study follows babies and young children (up to age 5) who have a genetic diagnosis of ataxia telangiectasia (A-T), a rare disease that affects movement and immunity. Researchers use brain and lung scans, blood tests, and movement analysis to spot early signs of disease progression. The goal is to find reliable markers that could be used in future trials of early-life treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could identify early signs of disease progression in young children with ataxia telangiectasia, paving the way for future treatments that start before symptoms appear.
- What could go wrong
- This is an observational study, not a treatment trial. It may not find clear markers, and results might not apply to all children with A-T.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Participants with A-T will be recruited principally via the National Paediatric A-T Clinic based at Nottingham University Hospitals NHS Trust. A second route for recruitment is the A-T Society, a UK charity that provides support and advocacy for people with A-T and their families. Participants without A-T or other conditions described in the exclusion criteria, will be infants and young children undergoing general anaesthesia at Nottingham University Hospitals NHS Trust for minor surgical procedures (e.g. circumcision, orchidopexy) or diagnostic MRI.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
1. Participants with A-T * Inclusion criteria * Genetic diagnosis of Ataxia Telangiectasia * Aged under two years old at the time of first recruitment * Parents/ guardians able to give informed consent * Exclusion criteria * Contraindication to MRI * Diagnosis of any other neurogenetic disease * On approved treatment targeting neurodegeneration in A-T at the time of first recruitment * Participating in the trial of novel therapy targeting neurodegeneration in A-T at the time of first recruitment NB - co-recruitment to other observational studies or trials is permitted. If a family chooses to enrol their child in an interventional study targeting neurodegeneration, provided that the intervention trial allows co-recruitment, we would like to retain the participant in the BOBCAT study until its conclusion. In this circumstance, the child's data would not be considered as part of the natural history dataset but would instead be used to demonstrate the feasibility of collecting longitudinal quantitative imaging and other biomarker data in people with A-T during infancy and early childhood. 2. Participants without A-T * Inclusion criteria * Child undergoing general anaesthesia at Nottingham University Hospitals NHS Trust for minor surgical procedures or diagnostic MRI. * Aged 0-5 years (to match the age range of participants with A-T throughout the longitudinal study). * Parents/ guardians able to give informed consent * Exclusion criteria * Diagnosis of any neurological or neurodevelopmental disease * Diagnosis of any other significant chronic childhood illness * On any long-term prescribed treatments
