Atara Biotherapeutics Provides a Clinical Update on EBVALLO and ATA3219
Atara Biotherapeutics, Inc. (NASDAQ: ATRA), a pioneering leader in T-cell immunotherapy, is making significant strides in its efforts to develop transformative therapies for cancer and autoimmune diseases. The company has recently announced that the U.S. Food and Drug Administration (FDA) has placed a clinical hold on its ongoing Investigational New Drug (IND) applications. These include the EBVALLO™ (tabelecleucel) program aimed at treating adult and pediatric patients two years and older with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD). Additionally, the hold also applies to ATA3219, which focuses on non-Hodgkin’s lymphoma and systemic lupus erythematosus treatment.
Clinical Holds and Their Impact
The FDA's decision to impose this clinical hold is primarily linked to unresolved Good Manufacturing Practice (GMP) compliance concerns at a third-party manufacturing facility, which were noted during a pre-licensure inspection referenced in the Complete Response Letter (CRL) issued earlier. It is important to note that while ATA3219 is produced at a fully compliant GMP-certified facility, it still relies on starting materials from the non-compliant site that was flagged during inspections. Thankfully, Atara's other manufacturing partner, FUJIFILM Diosynth Biotechnologies (FDB), located in Thousand Oaks, California, remains compliant and plays a pivotal role in Atara's manufacturing strategy moving forward.
Collaboration with the FDA
In light of these challenges, Atara and FDA officials have engaged in constructive dialogue to outline the necessary steps to lift the clinical holds on both drug candidates. Atara is committed to complying with all requirements and resolving these compliance issues swiftly to ensure patient safety and expedite progress in their clinical studies.
Leadership's Commitment to Resolution
“We intend to work closely with the FDA to address these issues as expeditiously as possible,” stated Dr. Cokey Nguyen, President and Chief Executive Officer of Atara. “Ongoing communication with the Agency is encouraging, and we are optimistic about our path toward resubmission that could lead to the lifting of the clinical hold. Keeping patient safety at the forefront is our utmost priority.”
