Pirtobrutinib Gains First-Line Nod for CLL/SLL
The FDA approved Eli Lilly's pirtobrutinib (Jaypirca) for first-line treatment of CLL/SLL without 17p deletion. The approval, based on the BRUIN CLL-313 trial, shows improved progression-free survival over bendamustine plus rituximab. Lilly highlights pirtobrutinib's advantage over covalent BTK inhibitors due to its reversible binding.
