Scientists at the Wistar Institute have discovered that a class of FDA-approved cancer drugs known as PARP1 inhibitors can effectively combat Epstein-Barr virus-driven lymphomas. The findings, published in the Journal of Medical Virology, demonstrate that these drugs, which work by blocking the activity of the PARP1 enzyme, can halt tumor growth by interfering with the EBV’s ability to activate key cancer-promoting genes.

Jaypirca (pirtobrutinib), a non-covalent Bruton tyrosine kinase inhibitor, plus a two-year venetoclax and rituximab regimen versus venetoclax and rituximab in patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma reduced the risk of disease progression or death by 45% (HR=0.55 [95% CI, 0.40-0.75]; p=0.0001), according to the results of the phase III BRUIN CLL-322 trial. The study met its primary endpoint of independent review committee-assessed progression-free survival.
The phase III frontMIND trial evaluating the efficacy and safety of tafasitamab (Monjuvi/Minjuvi), a humanized Fc-modified cytolytic CD19-targeting monoclonal antibody, and lenalidomide added to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone; Tafa-Len-R-CHOP) versus R-CHOP alone as a first-line treatment for adults with previously untreated diffuse large B-cell lymphoma or high-grade B-cell lymphoma, has produced positive results.
