A Modular, Phase I/II Study to Evaluate CT204V-CD19 x CD20 in Participants With Relapsed or Refractory B-Cell Malignancies. (CT204V)

6 novembre 2026 mis à jour par: AstraZeneca

A Modular, Phase I/II, Open-label, Single-arm, Multicenter, Dose Escalation and Dose Expansion Study to Evaluate the Safety, Tolerability, Cellular Kinetics, Pharmacodynamics, and Efficacy of CT204V-CD19 × CD20, an In Vivo Lentiviral Vector Gene Therapy Generating Dual Targeting Anti-CD19/CD20 Chimeric Antigen Receptor (CAR)-T Cells in Participants With Relapsed or Refractory B-Cell Malignancies

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of CT204V-CD19 × CD20, a dual targeting in vivo gene therapy generating anti-CD19/CD20 CAR-T cells in participants with R/R B-cell malignancies.

Description du régime IPD

Qualified researchers can request access to anonymized individual patient-level data from AstraZeneca group of companies sponsored clinical trials via the request portal Vivli.org. All requests will be evaluated as per the AZ disclosure commitment: https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.

Yes, indicates that AZ are accepting requests for IPD, but this does not mean all requests will be shared.

Délai de partage IPD

AstraZeneca will meet or exceed data availability as per the commitments made to the EFPIA PhRMA Data Sharing Principles. For details of our timelines, please rerefer to our disclosure commitment at https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.

Critères d'accès au partage IPD

When a request has been approved AstraZeneca will provide access to the anonymized individual patient-level data via secure research environment Vivli.org. Signed Data Usage Agreement (non-negotiable contract for data accessors) must be in place before accessing requested information.
