AbelZeta regains global rights to C‑CAR039 (Prizlon‑cel) and secures FDA IND clearance for large B‑cell lymphoma therapy
Executive summary: AbelZeta Pharma announced on August 16 2026 that it has reacquired worldwide rights to its C‑CAR039 CAR‑T construct (Prizlon‑cel) and received FDA IND clearance to evaluate the therapy in large B‑cell lymphoma. The IND clearance removes a major regulatory hurdle, enabling the company to move into clinical testing and potentially unlocking value through future partnership or commercialization.
Who is involved: AbelZeta Pharma, the U.S. Food and Drug Administration (FDA), and investors/partners interested in cell‑therapy oncology.
Likely next: AbelZeta expects to open a Phase 1 trial in late 2026, with first patient dosing projected for December 2026 and initial safety read‑outs anticipated by mid‑2027.
On August 16, 2026 AbelZeta Pharma announced that it has reacquired worldwide rights to its C‑CAR039 construct, branded Prizlon‑cel, and that the U.S. Food and Drug Administration has cleared its Investigational New Drug application for the treatment of large B‑cell lymphoma. The IND clearance permits the company to proceed with a Phase 1 clinical trial, marking a key regulatory milestone for the autologous CAR‑T program. Analysts note that regaining full global rights eliminates potential royalty or licensing encumbrances, streamlining future partnership or commercialization discussions.
