New Update: GOSH Approved to Join the BLT CPA Consortium Study!

As of 15 January 2026, Great Ormond Street Hospital has been officially approved to join the BLT Consortium Study focused on pediatric cerebral proliferative angiopathy (CPA)—an exciting step forward in global collaboration.

This approval means GOSH can now consent patients and share anonymized imaging and clinical data with Boston Children’s Hospital and The Hospital for Sick Children (SickKids) in Toronto. Together, the three centers will review cases, compare findings, and work as a team to better understand CPA.

Families who are interested in taking part can speak with their GOSH clinician or care team, or reach out to the CPA Research Foundation for connection. Participation involves sharing imaging and clinical information already collected during regular care. All data will be fully anonymized before being shared.

Because CPA is so rare, every case matters. The more information the consortium can gather, the more researchers and clinicians can learn about how CPA develops, how it behaves, and how treatments can be improved in the future. Families who choose to participate will be making a meaningful contribution to research that may help children with CPA worldwide. Please contact us with any questions!
