- Drug:
- Tabelecleucel (tab-cel)
- Announced Date:
- January 21, 2025
- Indication:
- Post-Transplant Lymphoproliferative Disease (PTLD)
Announcement
Atara Biotherapeutics, Inc announced that the U.S. Food and Drug Administration (FDA) has placed a clinical hold on Atara's active Investigational New Drug (IND) applications.
AI Summary
Atara Biotherapeutics, Inc. announced that the FDA has placed a clinical hold on its active Investigational New Drug (IND) applications for EBVALLO (tabelecleucel) and ATA3219 studies. The clinical hold affects the EBVALLO program, which treats adult and pediatric patients with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD), as well as ATA3219, a CD19-targeted CAR-T therapy for non-Hodgkin’s lymphoma and systemic lupus erythematosus.
This decision comes after the FDA identified GMP compliance issues during an inspection of a third-party manufacturing facility mentioned in a Complete Response Letter. The hold means that while patients already enrolled and likely to benefit may continue receiving treatment under current protocols, the enrollment of new patients has been paused. Atara is now working closely with the FDA to resolve these issues so that the clinical holds can be lifted as soon as possible.

AI Summary
Atara Biotherapeutics recently received a Complete Response Letter (CRL) from the FDA regarding its EBVALLO Biologics License Application (BLA). The CRL is for use of EBVALLO as a monotherapy to treat adult and pediatric patients two years and older who have Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD) and who have already received at least one prior therapy, including an anti-CD20 regimen. The FDA’s feedback was solely based on observations made during a routine inspection of a third-party manufacturing facility. It did not find any issues with the clinical efficacy or safety data, nor did it require any new clinical studies. Atara is working closely with the FDA, Pierre Fabre Laboratories, and the manufacturer to address these observations. The company is hopeful that once the manufacturing issues are resolved, the resubmitted application may be approved within six months.
