ASH 2024: Eli Lilly to highlight Jaypirca® data and promising BAFF-RxCD3 antibody research for B-Cell malignancies

Eli Lilly and Company (NYSE: LLY) today announced that data from studies of Jaypirca® (pirtobrutinib), a non-covalent (reversible) Bruton’s tyrosine kinase (BTK) inhibitor, will be presented at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition taking place Dec. 7-10 in San Diego.

In an oral presentation, Lilly will report results from the Phase 3 BRUIN CLL-321 study, which is evaluating pirtobrutinib versus idelalisib plus rituximab (IdelaR) or bendamustine plus rituximab (BR) in BTK inhibitor pretreated patients with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL). BRUIN CLL-321, which previously met its primary endpoint, is the first randomized Phase 3 study to evaluate an exclusively BTK inhibitor pretreated CLL population. The submitted abstract utilized a February 2024 data cut-off date, and the presentation will utilize an August 2024 data cut-off date.

Additionally, Lilly will have poster presentations that share analyses of real-world data, including looking at overall survival associated with treatment sequences in patients with CLL/SLL, and pre-clinical data for a first-in-class B-cell activating factor receptor (BAFF)-RxCD3 bispecific antibody for the treatment of certain B-cell malignancies.
