CAR-T Data Collection Initiative

Reporting is learning. By reporting data on patients treated with CAR T-cell therapies, one of the Immune Effector Cell (IEC) therapies, you contribute to academic research and regulatory decision making by health authorities. Ultimately, this supports EBMT’s mission to advance cellular and stem-cell based therapies and improve the lives of patients with blood-related disorders.

Data quality is fundamental to doing meaningful analyses. To ensure that we have complete and accurate data, EBMT invites centres that treat patients with commercial CAR T-cell therapies to participate in a Data Collection Initiative to support Post Authorisation Safety (PAS) studies mandated by the European Medicines Agency (EMA). Centres that participate will be financially compensated.

Reporting data

Background information

With the approval of the first CAR-T therapies, the EMA required MAHs to monitor their products in the long-term. The cellular therapy module of the EBMT Registry received a positive qualification opinion from the EMA, supporting the use of Real-World Data captured in the EBMT Registry to inform regulatory decision making by health authorities.

Frequently Asked Questions (FAQs)

What are the requirements for participation in the Data Collection Initiative?

  • To participate in the Data Collection Initiative on CAR-T therapies, a centre must, first and foremost, report data on all patients treated with (commercial) CAR-T therapies in the EBMT Registry database as per the standard data collection forms and processes (the Cellular Therapy form). This does not require any additional contracts and/or regulatory approvals. Consequently, this data collection is already ongoing and should continue. 
  • Secondly, if needed, help the EBMT Clinical Study Unit with obtaining regulatory approval for the updated informed consent form which allows patients to also consent to share the data collected in the Registry with EBMT’s collaboration partners including MAHs and health authorities. 
  • Thirdly, (re-)consent patients on the updated informed consent form. 
  • Finally, help set up contracts between your centre and EBMT which allows EBMT to reimburse your site for the data management efforts. (See the question “What contracts should my centre sign?” below).

What does my centre have to do when participating in the Data Collection Initiative?

  • You will need to complete the standard patient data in ProMISe and the cellular therapy data in the Castor EDC. In addition, we ask you to comply with data requests to ensure completeness and quality of the data.  
  • Data on patients treated with CAR-T therapies needs to be reported at the following time points:  baseline, 100 days, 6 months and then yearly up until 15 years have passed and at that time a 15-year follow-up will be conducted.
  • Also, we ask you to consent patients with the updated patient informed consent form, which asks patients to indicate whether they allow sharing of their data with EBMT collaboration partners and source data verification of their data. Only patients who explicitly consent to share their data with collaboration partners will be included in the dataset that is shared with these parties.

Why should my centre participate? What is in it for me?

  • Participation in the Data Collection Iinitiative is important because ‘reporting is learning’. The PAS studies are mandated by EMA because we lack information on the long-term safety and efficacy profiles of CAR-T therapies. As a prominent European medical community, we want to be in the lead of evidence generation of these promising treatments. Collectively we can generate robust real-world evidence to support regulatory decision making as well as scientific studies. 
  • The current protocols for the PAS studies are based on secondary use of Registry data. With this approach we prevent the creation of additional databases owned by marketing authorisation holders. The EBMT Registry makes data available to the scientific community and it avoids the need for centres to report data to multiple registries. By using a harmonised data collection form for cellular therapies, it will be easier to enter and compare data on different products. 
  • Centres will receive a generous reimbursement for their data management efforts. This money will be given for all patients treated with commercial CAR-T therapies who (re-)consent to sharing their pseudonymised data with MAHs for the sole purpose of the PAS studies. 
  • If you have a good study proposal for a CAR-T-related study, you can submit it to the relevant EBMT Working Parties or the GoCART Work Package on Scientific Excellence. When your proposal is selected/accepted, you will not only have access to the data from your centre but (indirectly) also to data from other centres in your country or the Registry as a whole. Working Parties have dedicated statisticians, data managers and study coordinators to support the conduct of the selected proposals.

What contracts should my centre sign?

  • The contracts for the Data Collection Initiative for the PAS studies are split in two parts; the Data Collection Master Agreement and the Product- Specific Agreement. The Data Collection Master Agreement governs the general data collection requirements that are identical for all CAR-T therapies. Whereas the shorter Product Specific Agreement specifies additional requirements for the individual CAR-T therapies. For each new PAS study you will only need to sign a new Product-Specific Agreement. 
  • By using this set-up, in which the Product-Specific Agreements are incorporated in the Data Collection Master agreement, we aim to reduce the time needed for contract negotiations and thus reduce the start-up timelines and burden for new cellular therapy products/PAS studies.
  • We also remind your centre to sign the Joint Controllership Agreement (JCA). This document governs all data processing activities between EBMT and the centre and is thus a prerequisite but not specific for the PAS studies. The JCA should be signed by all centres, including those who do not participate in the Data Collection Initiative for PAS studies.

Will my centre be reimbursed?

  • If your centre has agreed to particiapte in the Data Collection Initiative and has signed the relevant contracts, your centre will be reimbursed for all patients treated with commercial CAR-T therapy products that (re-)consent to allow sharing of their data with the marketing authorisation holders and health authorities for the purpose of the PAS study. You will be reimbursed when good quality data is entered and can be used in the PAS studies. The specific details of the recruitment period and payment schedule is provided in each Product-Specific Agreement.
  • For Kymriah® this means until the recruitment target of 2500 patients globally has been reached (competitive enrollment).
  • For Yescarta® this means all patients treated till 23 May 2025, unless the recruitment period is closed earlier per EBMT notification.
  • For Abecma® this means until the recruitment target of 300 patients in Europe has been reached (competitive enrollment).
  • More products are expected to follow in the near future.
