FDA granted traditional approval to pirtobrutinib, marketed as Jaypirca, for adults with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma previously treated with a covalent BTK inhibitor.

What to Watch
Watch sequencing after covalent BTK inhibitors and uptake in relapsed CLL/SLL care.
