FDA Grants Full Approval to Lilly’s Jaypirca

Share

FDA has granted Eli Lilly traditional approval for Jaypirca (pirtobrutinib) and its use in adults with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who were previously treated with a covalent BTK inhibitor. The action is based on confirmatory trial data and converts a 2023 accelerated approval, which covered patients who had received at least two prior lines of therapy including both a BTK inhibitor and a BCL-2 inhibitor.

Full approval was based on the randomized, open-label BRUIN-CLL-321 trial, which enrolled 238 previously treated CLL/SLL patients, according to an FDA release. Patients were randomized 1:1 to receive either pirtobrutinib, or investigator’s choice of idelalisib + rituximab (IR) or bendamustine + rituximab (BR).

The primary efficacy outcome measure was progression-free survival (PFS), as assessed by an independent review committee, FDA says. Median PFS was 11.2 months in the pirtobrutinib arm and 8.7 months in the investigator’s choice of IR/BR arm.

Jaypirca’s prescribing information carries Warnings for:

  • Serious infections
  • Hemorrhage
  • Cytopenias
  • Cardiac arrhythmias
  • Secondary malignancies
  • Hepatotoxicity
