PLK1 inhibition enhances Brentuximab vedotin efficacy in CD30-positive T-cell lymphoma via spindle assembly checkpoint activation.
Blocking a cell-cycle protein enhances an existing lymphoma drug in the lab, providing preclinical rationale to test this combination clinically.
This preclinical study demonstrates that PLK1 (polo-like kinase 1) inhibition acts synergistically with brentuximab vedotin (an antibody-drug conjugate targeting CD30) in CD30-positive peripheral T-cell lymphomas by exploiting the spindle assembly checkpoint, potentially overcoming resistance to BV monotherapy. The mechanistic combination strategy addresses an unmet need in PTCLs, where BV-incomplete responses and relapse remain frequent, and provides rationale for clinical investigation.
