The EBMT Registry 2020

New Registrations for HSCT in 2020

By the end of 2020, the entire Registry included at least 740,000 transplant registrations in total. New registrations during 2020 were around 10% lower than the previous year. We include the charts below. A probable reason for this is the impact of Covid 19.

16105 allografts and 20758 autografts were registered during 2020. Note that these numbers also include some transplants performed during earlier years.

New Registrations for Cellular Therapy in 2020

Through the network of our EBMT newsletter the Registy has actively encouraged centres to report on all cases involved in the treatment of patients using a CAR-T product whether commercial or investigational.  The 1st graph below illustrates the steady growth of new reported cases into the EBMT Registry during 2020 and the reflected number of centres.

All centres should continue to complete the current Cell Therapy Form outlined in ProMISe on a timely basis to create an accurate patient representation.

The 2nd graph represents a geographical approach in blue of all our reporting countries who are continually submitting data to the EBMT Registry. We look forward to welcoming more countries in 2021 as the number of CAR-T products on the market steadily increase.

Registry Upgrade

The Registry upgrade project has faced several challenges during the course of 2020, and these caused a complete halt of the data migration mid-year. Due to the high priority of this project, a thorough analysis on behalf of the EBMT was carried out. Looking at several technical as well as functional issues, this has resulted in a comprehensive Test plan created by the vendor. Together with the vendor, an approach was defined in order to address all the identified issues, find solutions and build towards a strong foundation to continue the project as a whole.

Outcomes of these tests are expected in the Q1 of 2021, whereafter new Validation and Test plans will be developed by the Registry in order to complete the data migration.

Registry Resource

In 2020 the Registry has transitioned form the previous Head, Debra Gordon, to the new Registry Director, Bas Middelkoop, who joined the EBMT Registry in December 2020.

Due to the loss of two members of staff in 2020 the Registry has been looking to replace the two vacancies and succeeded. Two experienced Data Analysts will join the Registry IT department in Q1 of 2021. Also the Registry is looking to expand the team further in 2021, giving the Registry team more hands and expertise to face the challenges for the coming year.
